The present disclosure relates to a vehicle security system and, in particular, to a collaborative vehicle security system that establishes communications between the vehicle security devices installed on neighboring vehicles for sharing the abnormal warning.

Description of Related Art

Most of the conventional anti-theft systems for vehicles are installed on the vehicle by the owner. The alarm is triggered by sensor to deter the thief. However, some thieves who know the technology of the anti-theft device can eliminate the alarm in a very short time so as to successfully steal the valuables in the vehicle.

Some parking lots or parking garages also provide functions of detecting abnormal state of parking space and notifying the manager, so as to intercept the stolen vehicles at the exit of the parking lots or garages, or notify the manager to arrive at the parking space that triggered the alarm to see what is happened. However, the manager of parking lots or garages may not be able to go to or arrive at the parking space that triggered the alarm in time for some reasons, so it is inevitable that important materials in the vehicles will be stolen.

Therefore, it is desired to provide a vehicle security system and a vehicle security device that can enhance the deterrence ability to achieve the anti-theft and anti-robbing function of vehicles.

In one embodiment, the central control host provides a parking-area partition function, and the routers are arranged in different parking areas, respectively.

As mentioned above, the collaborative vehicle security system and vehicle security device of this disclosure can establish the communication connections between the neighboring vehicles in the parking lots or garages, and the neighboring vehicles with communication connections can be grouped as one collaborative security group. Accordingly, the group members (the vehicles or the vehicle security devices) of the collaborative security group can share the information such as the safety abnormal event, the collaborative alarm activation signal, and/or the abnormal alarm activation signal. When one of the vehicles (vehicle security devices) senses the safety abnormal event, it will share the alarm activation signal with other vehicles (vehicle security devices) in the same collaborative security group, and these vehicles (vehicle security devices) will output warning alarms at the same time. At this time, the loud warning alarms (from multiple vehicles) can deter thieves and stop the possible crime events. In addition, the collaborative alarm activation signal can be transmitted or used to notify other users of the same collaborative security group and the manager of parking lot or garages, so that the users and manager can immediately and appropriately act based on the received collaborative alarm activation signal to eliminate the abnormal alarm. This is a multiple-to-multiple creative value-added anti-theft service. In general, the thief usually steals one car after one another and expects to return with a full load. Therefore, by sharing the abnormal alarm, the vehicle invaded by the thief can immediately receive the first-moment loud deterrent support from all other vehicles in the same collaborative security group. Besides, the other vehicle owners in the collaborative security group(s) are also afraid that their properties may be the next target of theft, so of course they are willing to share the abnormal alarms with other vehicle owners who do not know each other. According the system of this disclosure, there will be multiple vehicles turning on the loud warning alarms to deter thieves, and then the multiple vehicle owners may return to the parking lots to check what is happened, confirm and/or help eliminate abnormal alarm, and the multiple vehicle owners can collaborate with police at critical moment to catch the thief.

DETAILED DESCRIPTION OF THE DISCLOSURE

FIG. 1is a block diagram showing a collaborative vehicle security system according to a first embodiment of this disclosure. Referring toFIG. 1, the collaborative vehicle security system is composed of one or more vehicle security devices10and one central control host20. Each vehicle security devices10comprises a control module1, a communication module2, a timing module3, an alarm module4, a detection module5, and an alarm relieve module6. The central control host20comprises a central control module7, a communication module2, a timing module3, an alarm module4, and a database module8.

At first, the vehicle owner will install a vehicle security device10in his/her vehicle, and register the vehicle and the installed vehicle security device10to the collaborative vehicle security system. When the registered vehicle arrives the entrance of a parking lots, the central control host20can signally connect to the vehicle security device10through the communication module2to check whether this vehicle is registered or not, and to automatically obtain the required information with respect to the installed and registered vehicle security device10. Herein, the obtained information may include the contact information, the license plate number, and/or the automatic payment information, which can be used in the following notification procedure and payment procedure. In addition, the central control host20also returns the entrance time, the parking serial number, the network information of parking lots to the vehicle security device10, and the vehicle security device10will save the returned information. In this embodiment, the alarm module4will flash green light (e.g. flash5times per second) to indicate that the first step of parking is completed. After the vehicle enters the parking lots and is parked in the parking space, the user electronic device40of the vehicle owner communicates with the communication module2of the vehicle security device10to obtain the information from the central control host20, such as the entrance time, the parking serial number, the network information, or the likes. For example, this communication can be carried out by the APP installed on the user electronic device40. Then, the vehicle owner can press a confirm button to join a collaborative security group. In this embodiment, the alarm module4of the vehicle security device10will flash green light in another frequency (e.g. flash once per second) so as to finish a second step of parking. Afterwards, the communication module2outputs the confirm information and the IP address of the user electronic device40to the central control host20, which can notify the system that the vehicle owner agrees to use the service of the collaborative vehicle security system. The IP address of the user electronic device40can be used in the following broadcasting of abnormal warning alarm.

In addition, after the first step of parking and the green light starts to flash for5times per second, the vehicle owner can use a registered ID card or press buttons to reply the confirm information, which can notify the system that the vehicle owner agrees to use the service of the collaborative vehicle security system, via the alarm relieve module6of the vehicle security device10.

Referring toFIG. 2, the communication module2of the vehicle security device10can communicate with the neighboring vehicles (the communication module2of the vehicle security devices10installed in the neighboring vehicles) to establish a collaborative security group of a collaborative vehicle security system. That is, the neighboring vehicles (the vehicle security devices10installed in the neighboring vehicles) become the group members in the same collaborative security group. For example, as shown inFIG. 2, the vehicle security device #2joins two independent collaborative security groups60and70. In this case, the vehicle security device #2has a relatively low probability of losing communications with2independent collaborative security groups60and70at the same time. In this embodiment, all collaborative security groups and vehicles in the parking lots can signally connect to each other via the wireless local area network (in a grid-like manner), thereby ensuring the reliability and effectivity of the communications and connections between all vehicles in the collaborative security groups. For example, the vehicle security device #2scans the available communication signal with the strongest intensity from the communication module2of the neighboring vehicle security device #N, then randomly requests to join the collaborative security group60. In addition, the vehicle security device #2can accept the request from another neighboring vehicle security device #N+1 to join another collaborative security group70. These collaborative security groups can be established only if the communication signal emitted by the communication module2of the vehicle security device #2has the strongest intensity in this area. In this embodiment, the vehicle security device #2joins two collaborative security groups (W1=2) at the same time, including the collaborative security groups60and70. Each collaborative security group contains four vehicle security devices10(or four vehicles) (W2=4), so that the total number of primary group members in the collaborative security groups60and70(the first layer of the vehicle security device #2) can be calculated based on the following equation:

In this embodiment, each vehicle security device10in the collaborative security group60further joins another independent collaborative security group. Taking the vehicle security device #N as an example, the vehicle security device #N may be the vehicle security device #S of another collaborative security group99. Of course, the collaborative security group connections of the vehicle security devices #1and #3can be established based on the above example. In this case, the collaborative security group99is defined as the second layer of the vehicle security device #2. If the group members of the first and second layers of the of the vehicle security device #2are all invited to the warning alarm action corresponding to an abnormal event, the total amount of the invited group members can be calculated based on the following equation:

The detection module5of the vehicle security device10detects possible abnormal events such as vehicle displacement, door opening, vehicle seat occupied at any time for the vehicle parked in the parking space, and initiates an abnormal alarm and broadcasts them to all vehicle security devices10in the collaborative security group when detecting out any of the abnormal events. Therefore, all the vehicle security devices10can together turn on the loud warning sound to deter the thief. The abnormal alarm is also transferred to the remote vehicle owner, other vehicle owners of the same collaborative security group, and the parking lot manager at the same time, so that the vehicle owners and parking lot manager can take appropriate rescue actions based on the types of abnormal alarms received. In general, the thief usually steals one car after one another and expects to return with a full load, so the vehicle owners who receive the notification of abnormal alarm may consider that his/her vehicle may be the next target of the thief and is willing to return to the parking lots to check what is happened and to assist to relieve the abnormal alarm. In some cases, the multiple vehicle owners or managers who return to the parking lots can collaborate with police to catch the thief or robber. Car robbing and or kidnapping incidents in parking lots have been heard frequently. If the vehicle owners participate in the collaborative security group of the collaborative vehicle security system of the present disclosure, it is possible to prevent the occurrence of unfortunate incidents or reduce personal and financial losses by broadcasting and transferring the abnormal alarms to all of the group members.

The sharing of abnormal alarms in the above-mentioned example is achieved through a small wireless local area network in which all the vehicle security devices10are mutually connected in grid-like manner, and the central control host20does not participate in this system. In this embodiment, the vehicle security device10can further output the abnormal alarm to the remote user electronic device via the Internet connection ability of the central control host20. This completes the broadcasting and transferring through the small wireless local area network and the remote Internet. The wireless local area network technology used by the communication module2can be Wi-Fi, Zigbee, Bluetooth, LoRa, Short Distance Radio (SDR), etc. While considering the transmission distance and bandwidth requirements, Wi-Fi can be prioritized choice.

The communication module2of the central control host20can externally connect the user electronic device40and the backup server50via the cloud network30, so as to output the abnormal alarm to the user electronic device40and the backup server50, or receive the control signal from the user electronic device40and the backup server50. The user electronic device40may be a mobile communication device, such as a smart phone, a tablet computer, etc. In addition, the central control host20can also simultaneously upload information about the remaining number of individual parking spaces in the parking lots, parking garages, or curbside parking spaces to the backup server50, so that it can uniformly control all parking lots or garages as well as the parking spaces. The Internet connection capability of the central control host20is prioritized by wired optical fiber or coaxial cable, and3G, 4G or 5G telecommunication communication network can also be used to connect to the Internet.

Referring toFIG. 3, the central control host20can operate alone, or cooperate with one or more central control routers21to expand the total amount of vehicle management in the parking lots, extend the distance of the reliable communication connection of the parking lots, and partition the parking management areas. This disclosure is also applicable to the curbside parking and payment system managed by the government unit, which can save the salary expenditure of the billing staff. The communication modules2are connected one after one in series and provide routing services for network packets. Only one of the communication modules2directly communicates with the communication module2of the central control host20. Each central control router21is communicated to the corresponding one of the collaborative security groups. When an abnormal alarm occurs in one collaborative security group, the abnormal alarm will be sent to the central control host20through the central control routers21in the form of network packets, and then it is uniformly judged by the central control host20and the appropriate actions will be taken. The central control routers #1. . . #M can be set in the appropriate positions of a large surface parking lots to cover the reliable communication connection distances of all collaborative security groups within the area. In addition, the central control routers #1. . . #M can be set in different floors of a parking tower.

Referring toFIGS. 1 and 3, the timing module3is configured to obtain a time stamp, which can record the time of vehicle entering and leaving the parking lots, the time of occurrence of abnormal alarm, and the time of relieving the abnormal alarm by the group member of the collaborative security group or the parking lot manager.

Referring toFIGS. 1 and 3, the alarm module4is controlled by the control module1to display the corresponding LED lights according to the type of abnormal alarm sent from the detection module5, and at the same time emit a corresponding warning sound through the buzzer. The type of abnormal alarm may be vehicle displacement, door opening, vehicle seat occupied, etc. In addition, with different LED lights and/or warning sounds, it can be further distinguished whether the source of the abnormal alarm is the vehicle itself or from a sharing event (from other group members).

As shown inFIGS. 1 and 3, the warning relieve module6is used to (1) reply the confirmation of agreeing to use the advance service of the collaborative security system to the central control host20, wherein the green light may change from flashing for 5 times per second to flashing once per second in this procedure; (2) accept a relieve operation performed by the vehicle owner of the collaborative security group or the parking lot manager, wherein the time of performing the relieve operation will be recorded for determining to gift a gratitude bonus to the person who performed the relieve operation (e.g. the first person arrived the parking space of the alerting vehicle); and (3) pay the amount for this parking.

As mentioned above, the control module1receives the abnormal alarm from the detection module5through the communication module2. After determining the type of the abnormal alarm in view of the preset collaborative security conditions, the alarm module4will output the corresponding LED light and the corresponding warning sound (by buzzer), and the abnormal alarm will also be broadcast to all the group members in the collaborative security group through the small wireless local area network of the collaborative security group. Afterwards, all the group members will turn on the loud warning sound to deter theft. Then, the abnormal alarm message can be sent to the remote user electronic devices, so that the vehicle owners and/or the parking lot manager can take immediate rescue action after checking the received message.

Besides, referring toFIGS. 1 to 3, the backup server50may include a database for recording (1) the registered information of the user (the vehicle and the vehicle security device) such as the user's contact information, the license plate number, and/or the automatic payment information; (2) the time information about the abnormal alarm occurrence and relieving the abnormal alarm; (3) the information about parking lot serial numbers, vehicle access and payment information, and information of available parking spaces, which can be provided to update in real time for the vehicle owners.

FIG. 5is a schematic diagram showing a vehicle security device A1according to a second embodiment of this disclosure. As shown inFIG. 5, the vehicle security device A1comprises a control module A11, a detection module A12, a communication module A13, and an alarm module A14. In one aspect, the control module A11, the detection module A12, the communication module A13and the alarm module A14can be integrally configured in one housing to form the vehicle security device A1. In this aspect, the user can install the vehicle security device A1at any proper position inside or outside the corresponding vehicle. In another aspect, the control module A11, the detection module A12, the communication module A13and the alarm module A14of the vehicle security device A1are separated components. In this aspect, the user can install the control module A11, the detection module A12, the communication module A13and the alarm module A14at proper positions inside or outside the corresponding vehicle. Of course, the control module A11, the detection module A12, the communication module A13and the alarm module A14of the vehicle security device A1can also be partially integrated and partially separated, and this disclosure is not limited.

As shown inFIG. 5, the detection module A12is electrically or signally connected to the control module A11, and is configured to detect at least one safety abnormal event E of the corresponding vehicle. In this embodiment, the control module A11can be, for example but not limited to, a controller or a micro processer, and the detection module A12can be, for example but not limited to, a vibration sensor, a hall sensor, a pressure sensor, a gyroscope, a GPS device, etc. In addition, the detected at least one safety abnormal event E may be, for example but not limited to, vehicle displacement, door opening, vehicle seat occupied, etc. For example, when the vehicle moves, it may trigger the vibration sensor, gyroscope or GPS device. Therefore, the detection module A12will determine that a safety abnormal event E is detected out. In addition, when the door is opened, it may trigger the vibration sensor and/or the Hall sensor, so the detection module A12will determine that a safety abnormal event E is detected out. In addition, when a person is sitting on the car seat, the vibration sensor and/or the pressure sensor may be triggered, so the detection module A12will determine that a security abnormal event E is detected out. It should be noted that the above illustrations are only examples, and the present disclosure is not limited to the above aspects.

As shown inFIG. 5, the communication module A13is electrically or signally connected to the control module A11and is configured to optionally output at least one collaborative alarm activation signal Sc or receive at least one collaborative alarm activation signal Sc′. In this embodiment, the control module A11may control the communication module A13to output at least one collaborative alarm activation signal Sc, or the communication module A13may receive at least one collaborative alarm activation signal Sc′ from outside (e.g. another vehicle security device) and send the received collaborative alarm activation signal Sc′ to the control module A11. In this embodiment, the communication mode of the communication module A13can be, for example but not limited to, Wi-Fi, Zigbee, Bluetooth, LoRa, Short Distance Radio (SDR), and/or 3G, 4G or 5G telecommunication communication network.

Referring toFIG. 5, the alarm module A14is configured to output a warning alarm. In this embodiment, the warning alarm outputted by the alarm module A14can be, for example but not limited to, a sound alarm, a light alarm, a vibration alarm, or the likes. Furthermore, the intensity of the warning alarm outputted by the alarm module A14is variable. For example, the warning alarm can be a sound alarm with different volumes, a light alarm with different light colors or different brightness, or a vibration alarm with different vibration intensities.

In this embodiment, when the detection module A12detects out at least one safety abnormal event E, the control module A11generates an abnormal alarm activation signal Se and a collaborative alarm activation signal Sc according to the detection result. Then, the alarm module A14outputs the warning alarm according to the abnormal alarm activation signal Se, and the communication module A13outputs the collaborative alarm activation signal Sc by broadcasting or signal transmission at the same time.

In addition, when the communication module A13receives at least one collaborative alarm activation signal Sc′ from outside, the control module A11controls the alarm module A14, according to the received collaborative alarm activation signal Sc′, to output the warning alarm.

In addition, as shown inFIG. 5, the vehicle security device A1of this embodiment further comprises an alarm relieve module A15for accepting a relieve operation to relieve the warning alarm outputted by the alarm module A14. Specifically, after the alarm module A14outputs the warning alarm, the vehicle owner of the vehicle or any authorized person (e.g. the parking lot manager or other vehicle owners who use the same vehicle security devices) may rush to the alarm site (e.g. where the vehicle and the vehicle security device A1are located) as soon as possible. After the safety abnormal event E is resolved, the person arrived the alarm site can perform a relieve operation on the alarm relieve module A15to relieve the warning alarm outputted by the alarm module A14. For example, the relieve operation performed on the alarm relieve module Al5can be inputting a password, sensing barcode, QR code or a chip, or the likes, but this disclosure is not limited thereto.

In addition, as shown inFIG. 5, the vehicle security device A1of this embodiment further comprises a timing module A16configured to provide at least one time stamp, which is corresponding to at least one of the safety abnormal event E, the collaborative alarm activation signal Sc or Sc′, the warning alarm, and the abnormal alarm activation signal Se. Specifically, when the detection module A12detects out at least one safety abnormal event E, the timing module A16can provide a time stamp for this safety abnormal event E. Accordingly, the vehicle owner or the authorized person can operate the user electronic device (e.g. a mobile phone) to retrieve the time point when the safety abnormal event E was happened.

In this embodiment, the communication module A13can further retransmit the received collaborative alarm activation signal Sc′. In other words, when the communication module A13receives the collaborative alarm activation signal Sc′ from outside, except for initiating the control module A11to control the alarm module A14to output the warning alarm, the communication module A13further retransmits the received collaborative alarm activation signal Sc′ to the neighboring vehicle security device(s) Al. Accordingly, the neighboring vehicle security device(s) Al can also output the warning alarm(s) according to the collaborative alarm activation signal Sc′.

As mentioned above, the vehicle security device A1outputs at least one warning signal Sw to a mobile communication device40′ (or the user electronic device40as shown inFIG. 2), which can be, for example but not limited to, a mobile phone. In this embodiment, the warning signal Sw comprises at least one of the safety abnormal event E, the collaborative alarm activation signal Sc or Sc′, the warning alarm, and the abnormal alarm activation signal Se, and the corresponding time stamp.

In addition, a collaborative vehicle security system B of the second embodiment comprises a plurality of the above-mentioned vehicle security devices A1. For example, a plurality of vehicles are parked in a parking lots, and at least a part or all of the vehicles are respectively installed with the above-mentioned vehicle security devices A1. When one of the vehicle security devices outputs the collaborative alarm activation signal Sc, another one of the vehicle security devices receives the collaborative alarm activation signal Sc, and outputs the warning alarm according to the received collaborative alarm activation signal Sc.

In this embodiment, the intensity of the warning alarm is variable based on the distance between the vehicle security device A1outputting the warning alarm and a signal source of the collaborative alarm activation signal Sc (i.e., the vehicle security device A1detects out the safety abnormal event E and outputs the collaborative alarm activation signal Sc). In this embodiment, the collaborative vehicle security system B further gifts a gratitude bonus to the user (the vehicle owner or parking lot manager) who performed the relieve operation with the alarm relieve module A15. In this embodiment, the collaborative vehicle security system B further comprises a database DB recording registration information of each vehicle security device A1. Herein, the warning signal further comprises the registration information of the vehicle security device A1, which outputs the collaborative alarm activation signal Sc.

To make this disclosure more comprehensive, the detail operation of the collaborative vehicle security system B of this embodiment will be described with reference toFIG. 6A. Herein,FIG. 6Ais a schematic diagram showing the collaborative vehicle security system B according to the second embodiment of this disclosure.

Referring toFIGS. 5 and 6A, a vehicle owner installed a vehicle security device A1aon his/her vehicle. After this vehicle is parked in a parking lots, the communication module A13of the vehicle security device A1acan communicate with the neighboring vehicles within a certain neighboring region. For example, the communication module A13of the vehicle security device A1acommunicates with the communication modules A13of the vehicle security devices A1b,A1cand A1din the neighboring vehicles, and these vehicle security devices A1a,A1b,A1cand A1dwill together form a collaborative security group B1of the collaborative vehicle security system B and become the group members of the same collaborative security group B1. Similarly, the collaborative vehicle security system B also includes other collaborative security groups B2and B3. As shown inFIG. 6A, the vehicle security device A1djoins two independent collaborative security groups B1and B2, and the vehicle security device A1gjoins two independent collaborative security groups B2and B3. In addition, the collaborative security groups B1, B2and B3as well as the vehicle security devices A1a˜A1jthereof are signally connected to the central control host C1of this parking lots. The central control host C1can access a database DB via Internet so as to obtain the related registration information of the vehicle security devices A1a˜A1j.Moreover, the vehicle security devices A1a˜A1jcan transmit information packets to the mobile communication device40′ through the central control host C1via the Internet. In addition, the vehicle security devices A1a˜A1jcan send short messages to the mobile communication device40′ through the central control host C1via the communication network. Of course, each of the vehicle security devices A1a˜A1jcan directly communicate with the mobile communication device40′ of the corresponding vehicle owner via, for example, Internet or communication network. To be noted, the configurations and functions of the collaborative vehicle security system B of the second embodiment can refer to those of the collaborative vehicle security system of the first embodiment as shown inFIG. 2, so the detailed descriptions thereof will be omitted.

For example, after the collaborative security groups B1, B2and B3are established, when one vehicle encounters an abnormal event (e.g., the detection module A12of the vehicle security device A1adetects out a safety abnormal event E), the control module A11of the vehicle security device A1awill generate an abnormal alarm activation signal Se and a collaborative alarm activation signal Sc. Then, the alarm module A14of the vehicle security device A1aoutputs the warning alarm according to the abnormal alarm activation signal Se. At the meanwhile, the communication module A13of the vehicle security device A1aoutputs the collaborative alarm activation signal Sc to the other vehicle security devices A1b˜A1dof the same collaborative security group B1.

Next, after the communication modules A13of the vehicle security devices A1b˜A1dreceive the collaborative alarm activation signal Sc outputted from the communication module A13of the vehicle security device A1a,the control modules All of the vehicle security devices A1b˜A1dcontrol the corresponding alarm modules A14to output warning alarms according to the received collaborative alarm activation signal Sc.

In addition, since the vehicle security device A1dis the group member in both of the collaborative security groups B1and B2, the communication module A13of the vehicle security device A1dcan further retransmit the collaborative alarm activation signal Sc to other vehicle security devices A1e˜A1gin the collaborative security group B2. Afterwards, the control modules A11of the vehicle security devices A1e˜A1gcan control the corresponding alarm modules A14to output warning alarms according to the received collaborative alarm activation signal Sc.

Similarly, since the vehicle security device A1gis the group member in both of the collaborative security groups B2and B3, the communication module A13of the vehicle security device A1gcan further retransmit the collaborative alarm activation signal Sc to other vehicle security devices A1h˜A1jin the collaborative security group B3. Afterwards, the control modules A11of the vehicle security devices A1h˜A1jcan control the corresponding alarm modules A14to output warning alarms according to the received collaborative alarm activation signal Sc.

In brief, when the detection module A12of the vehicle security device A1adetects out the safety abnormal event E, not only the alarm module A14of the vehicle security device A1aoutputs the warning alarm, but also the alarm modules A14of the vehicle security devices A1b˜A1jinstalled in the neighboring vehicles output the warning alarms. These large amount and loud warning alarms can provide an amplified warning function, and the thief cannot quickly eliminate the alarm sound. Therefore, the collaborative vehicle security system B of the present disclosure can indeed achieve the effect of anti-theft and anti-robbing

Moreover, in this embodiment, the intensity of the warning alarm can be variable based on the distance between the vehicle security device outputting the warning alarm and a signal source of the collaborative alarm activation signal Sc. Specifically, as shown inFIG. 6A, in the case that the detection module A12of the vehicle security device A1adetects out a safety abnormal event E, the alarm module A14of the vehicle security device A1awill output a warning alarm with a first level intensity, the other vehicle security devices A1b˜A1din the collaborative security group B1will output a warning alarm with a second level intensity, the other vehicle security devices A1e˜A1gin the collaborative security group B2will output a warning alarm with a third level intensity, and the other vehicle security devices A1h˜A1jin the collaborative security group B3will output a warning alarm with a fourth level intensity. Wherein, the first level intensity is the strongest intensity, and the fourth level intensity is the weakest intensity. For example, the alarm module A14of the vehicle security device A1aoutputs the loudest alarm sound, the most obvious light color (e.g. red light), the highest flashing frequency, or the like. The alarm module A14of the vehicle security devices A1b˜A1doutput the second loudest alarm sound, the second most obvious light color (e.g. green light), the second highest flashing frequency, or the like, and so on. Accordingly, when the vehicle owner or the authorized person (e.g., the parking lot manager or other vehicle owners) rushes to the alarm site (e.g. where the vehicle and the vehicle security device A1aare located), the exact location of the vehicle encountering the safety abnormal event E can be quickly confirmed, and the abnormal event can be quickly eliminated. After eliminating the abnormal event, the person arrived the alarm site can perform a relieve operation on the alarm relieve module A15of the vehicle security device A1ato relieve the warning alarm outputted by the alarm module A14.

In addition, when the collaborative vehicle security system B of this embodiment is applied to a wide parking region, such as a large surface parking lots or a parking tower with multiple floors, some vehicle security devices may be far away from the central control host C1and cannot directly signally connect to the central control host C1. In this case, one or more routers can configured to expand the total amount of vehicle management in the parking lots, extend the distance of the reliable communication connection of the parking lots, and partition the parking management areas. As shown inFIG. 6B, the collaborative vehicle security system B is configured with a plurality of routers21aand21b,which are signally connected to the central control host C1. For example, the routers21aand21bcan be individually signally connected to the central control host C1by wireless or wired method, or the routers21aand21bcan be signally connected to the central control host C1one after one in series. As shown inFIG. 6B, the collaborative security groups B1, B2and B3are directly signally connected to the central control host C1, the collaborative security groups B4and B5are signally connected to the router21aand then connected to the central control host C1through the router21a,and the collaborative security group B6is signally connected to the router21band then connected to the central control host C1through the routers21aand21b. Taking a parking tower as an example, the central control host C1is installed at the entrance of the first floor of the parking tower, and each floor is configured with a corresponding router. For example, in a 12-floor parking tower, the second to twelfth floors are each configured with one router (totally 11 routers are configured). In this case, the vehicles parking at each floor can together form one or more collaborative security groups, and the vehicle security devices of this floor can signally connected to the central control host through the corresponding router. The configuration of the router can refer to the related description of the embodiment as shown inFIG. 3, so the detailed descriptions thereof will be omitted.

In summary, the collaborative vehicle security system and vehicle security device of this disclosure can establish the communication connections between the neighboring vehicles in the parking lots or garages, and the neighboring vehicles with communication connections can be grouped as one collaborative security group. Accordingly, the group members (the vehicles or the vehicle security devices) of the collaborative security group can share the information such as the safety abnormal event, the collaborative alarm activation signal, and/or the abnormal alarm activation signal. When one of the vehicles (vehicle security devices) senses the safety abnormal event, it will share the alarm activation signal with other vehicles (vehicle security devices) in the same collaborative security group, and these vehicles (vehicle security devices) will output warning alarms at the same time. At this time, the loud warning alarms (from multiple vehicles) can deter thieves and stop the possible crime events. In addition, the collaborative alarm activation signal can be transmitted or used to notify other users of the same collaborative security group and the manager of parking lot or garages, so that the users and manager can immediately and appropriately act based on the received collaborative alarm activation signal to eliminate the abnormal alarm. This is a multiple-to-multiple creative value-added anti-theft service. In general, the thief usually steals one car after one another and expects to return with a full load. Therefore, by sharing the abnormal alarm, the vehicle invaded by the thief can immediately receive the first-moment loud deterrent support from all other vehicles in the same collaborative security group. Besides, the other vehicle owners in the collaborative security group(s) are also afraid that their properties may be the next target of theft, so of course they are willing to share the abnormal alarms with other vehicle owners who do not know each other. According the system of this disclosure, there will be multiple vehicles turning on the loud warning alarms to deter thieves, and then the multiple vehicle owners may return to the parking lots to check what is happened, confirm and/or help eliminate abnormal alarm, and the multiple vehicle owners can collaborate with police at critical moment to catch the thief
