DETAILED DESCRIPTION
Reference will now be made in detail to exemplary embodiments of the disclosure, which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
FIG. 1 illustrates a structure schematic diagram of an exemplary remote monitoring system based on an LED lighting device consistent with the disclosed embodiments. As shown in FIG. 1, the remote monitoring system may include an LED lighting device 1, a wireless router 2, a smart terminal 3 and a cloud server 4, where a monitoring computer program is installed in the smart terminal 3, and a Wi-Fi module 13 and a microwave sensor module 14 are installed in the LED lighting device 1. Certain components or devices may be omitted and other components or devices may be included in embodiments consistent with the present disclosure.
The Wi-Fi module 13 and the microwave sensor module 14 are electrically connected. The microwave sensor module 14 is configured to detect object movements within an effective range. The Wi-Fi module 13 performs real-time data acquisitions on the microwave sensor module 14 through a one-channel Analog to Digital Converter (ADC). The Wi-Fi module 13 uploads the data of the microwave sensor module 14 in real time, and other data and status of the LED lighting device 1. In addition, when the Wi-Fi module 13 detects that there is an object moving within the effective range through the microwave sensor module 14, the Wi-Fi module 13 controls the LED lighting device 1 to giving a flashing alarm at a certain frequency or give an audible alarm through a horn embedded in or linked to the LED lighting device or outside the LED lighting device until the Wi-Fi module 13 detects that there is no object moving within the effective range. The object refers to any living or non-living object that can change locations in an effective range. For example, objects may include people (e.g., pedestrians), cars, bicycles, animals, etc.
The communication interface between the microwave sensor module 14 and the Wi-Fi module 13 may be ADC, Inter-Integrated Circuit (I2C), Universal Asynchronous Receiver Transmitter (UART) or General Purpose Input/Output (GPIO).
The smart terminal 3 may be directly connected to the wireless router 2. The smart terminal 3 may be also connected to the Internet through a mobile network (e.g., 2G, 3G or 4G communication network). When the smart terminal 3 is directly connected to the wireless router 2, the LED lighting device 1 accesses a wireless network provided by the wireless router 2 through the Wi-Fi module 13. At this point, the smart terminal 3 and the Wi-Fi module 13 are on the same network segment. The smart terminal 3 accesses the Internet through the wireless router 2. The Wi-Fi module 13 performs real-time data acquisition on the microwave sensor module 14 through a one-channel ADC. In addition, the Wi-Fi module 13 uploads the data of the microwave sensor module 14 in real time, and other data and status of the LED lighting device 1 to the cloud server 4. Through the Internet, an APP program in the smart terminal 3 checks regularly the data and status of the LED lighting device 1 stored in the cloud server 4. When the cloud server 4 receives information such as a message “there is an abnormal object moving within the effective range”, the cloud server 4 sends the information to the smart terminal 3 in real time.
When the smart terminal 3 is connected to the Internet through the mobile network (e.g., 2G, 3G or 4G communication network), the wireless router 2 accesses the Internet, and the LED lighting device 1 accesses the wireless network provided by the wireless router 2 through the Wi-Fi module 13. The Wi-Fi module 13 performs real-time data acquisition on the microwave sensor module 14 through the one-channel ADC. In addition, the Wi-Fi module 13 uploads the data of the microwave sensor module 14 in real time, and other data and status of the LED lighting device 1 to the cloud server 4. Through the Internet, the APP program in the smart terminal 3 checks regularly the data and status of the LED lighting device 1 stored in the cloud server 4. When the cloud server 4 receives the information such as a message “there is an abnormal object moving within the effective range”, the cloud server 4 sends the information to the smart terminal 3 in real time.
In addition, the LED lighting device 1 may be set to a microwave monitoring mode and a non-microwave monitoring mode according to time and daily schedules of a person through the cloud server 4, thereby avoiding too many false alarms. When the LED lighting device 1 is in the microwave monitoring mode, a result of the microwave monitoring is valid.
Moreover, the number of the LED lighting device 1 in the LED monitoring system may be one or more, and the specific number can be increased or decreased according to actual needs.
The smart terminal 3 (also known as the terminal device) may refer to any appropriate user terminal with certain computing capabilities, such as a personal computer (PC), a work station computer, a server computer, a hand-held computing device (tablet), a smartphone or mobile phone, or any other user-side computing device. In certain embodiments, the smart terminal 3 may be a mobile terminal device, such as a smartphone, a tablet computer, or a mobile phone, etc. The smart terminal 3 may be implemented on any appropriate computing platform. The smart terminal 3 may be used by a user to connect to the wireless network and make requests to the cloud server 4.
Further, the cloud server 4 may refer to one or more server computers configured to provide certain services. The cloud server 4 may include one or more processors to execute computer programs in parallel.
FIG. 2 illustrates a flow chart of an exemplary remote monitoring method based on an LED lighting device consistent with the disclosed embodiments. In a search area, at least one LED lighting device is installed. The search area may be any region being monitored according to the present disclosure. Such a search area is not limited to any particular area and may include any known object therein. For example, such search areas may be indoor or outdoor, may be on the ground or in the air, etc. Various illustrative examples of search areas may include defined areas such as a room, a parking garage, a parking lot, a lobby, a bank, a playground, a pedestrian mall, etc. The number of the LED lighting device in the LED monitoring system may be one or more, and the specific number of the LED lighting device can be set according to actual needs. A Wi-Fi module and a microwave sensor module may be integrated into the LED lighting device, and the Wi-Fi module and the microwave sensor module are electrically connected. The Wi-Fi module and the microwave sensor module may be designed so that the shapes of the modules conform to the shape of the LED lighting device. In addition, the remote monitoring system also includes a wireless router, a cloud server and a smart terminal. A monitoring computer program is installed in the smart terminal. The smart terminal may be directly connected to the wireless router. The smart terminal may be also connected to the Internet through a mobile network (e.g., 2G, 3G or 4G communication network). As shown in FIG. 2, the process may include the following steps.
First, the LED lighting device accesses a wireless network provided by the wireless router through the Wi-Fi module (Step 201).
Then, the Wi-Fi module performs real-time data acquisition of the data generated by the microwave sensor module (Step 202). The Wi-Fi module may perform real-time data acquisition on the microwave sensor module through a one-channel Analog to Digital Converter (ADC). The microwave sensor module can detect whether there is an object moving within an effective range. When the Wi-Fi module detects that there is an object moving within the effective range through the microwave sensor module, the Wi-Fi module controls the LED lighting device to flash at a certain frequency or give an audible alarm through a horn embedded in or linked to the LED lighting device or outside the LED lighting device until the Wi-Fi module detects that there is no object moving within the effective range.
Further, the Wi-Fi module uploads the data of the microwave sensor module to the cloud server in real time (Step 203). The Wi-Fi module may upload the data of the microwave sensor module in real time, and other data and status of the LED lighting device to the cloud server. The cloud server stores the data and status of the LED lighting device.
The cloud server may receive information such as “there is an abnormal object moving within the effective range” uploaded by the Wi-Fi module (Step 204). The cloud server may send the information “there is an abnormal object moving within the effective range of light X” to the smart terminal in real time (Step 205).
The smart terminal checks data and status of the LED lighting device stored in the cloud server, such that a home environment is monitored (Step 206). Through the Internet, an APP program installed in the smart terminal may check regularly the data and status of the one or more LED lighting devices stored in the cloud server.
The embodiments disclosed herein are exemplary only. Other applications, advantages, alternations, modifications, or equivalents to the disclosed embodiments are obvious to those skilled in the art and are intended to be encompassed within the scope of the present disclosure.
INDUSTRIAL APPLICABILITY AND ADVANTAGEOUS EFFECTS
Without limiting the scope of any claim and/or the specification, examples of industrial applicability and certain advantageous effects of the disclosed embodiments are listed for illustrative purposes. Various alternations, modifications, or equivalents to the technical solutions of the disclosed embodiments can be obvious to those skilled in the art and can be included in this disclosure.
In one embodiment consistent with the present disclosure, a smart home system may include a plurality of LED lighting devices with integrated Wi-Fi modules and microwave sensor modules. Each LED lighting device may be responsible for monitoring one area of a home. A user may use a smart terminal to check the data and status of the LED lighting devices stored in a cloud server. For example, LED lighting device A may monitor one area of the driveway. LED lighting device B may monitor the living room, etc. By tracking multiple LED lighting devices with integrated Wi-Fi modules and microwave sensor modules a user may monitor the movements of various areas of a home, an office, etc.
In another embodiment consistent with the present disclosure, a smart home system may include a plurality of LED lighting devices with integrated Wi-Fi modules and microwave sensor modules. The plurality of LED lighting devices may be programmed to control each other. For example, LED lighting device A may monitor one area of the driveway. LED lighting device B may monitor the living room. When LED lighting device A detects certain movements in its effective area, it may send a signal through the Wi-Fi module to turn on LED lighting device B (e.g., a light in the living room). This type of lighting setups may be implemented as an anti-theft system. In another example, LED lighting device A may monitor one area of the driveway. LED lighting device C may monitor the garage. When LED lighting device A detects certain movements in its effective area during certain time of the day (e.g., during the time occupants of the home may come home), it may send a signal through the Wi-Fi module to turn on the light in LED lighting device B (e.g., a light in the garage).
Comparing with the existing technology, a Wi-Fi module and a microwave sensor module are integrated in an LED lighting device in this disclosure. Through the Internet, a smart terminal may check regularly the data and status of the LED lighting device stored in a cloud server; or when the cloud server receives the information (e.g., “there is an abnormal object moving within the effective range”) sent from the Wi-Fi module, the cloud server sends the information to the smart terminal in real time. Therefore, wireless and remote monitoring can be implemented through the smart terminal (e.g., a personal computer, a mobile phone, and so on).
