Title: Information communication technology-based unmanned alert system

Description:
TECHNICAL FIELD 
     The present invention relates to an information communication technology (ICT)-based unmanned security system for collecting peripheral status information using various types of unmanned surveillance devices, and wirelessly transmitting the collected information to a mobile device using a long term evolution (LTE) network. 
     BACKGROUND ART 
     Currently, for basic military deterrence, the Republic of Korea essentially requires an efficient security system for blocking intruders from the Democratic People&#39;s Republic of Korea. 
     The Republic of Korea is bounded by the sea on three sides and by the land on one side. Therefore, enemies can intrude from both the land (e.g., the demilitarized zone (DMZ)) and the sea, and coastal areas are very vulnerable to intrusion. 
     Compared to land surveillance areas, coastal surveillance areas are very wide and do not have sufficient troops, and thus no-surveillance zones can occur. 
     To solve the difficulties of surveillance, required is development of a technology capable of checking movements of an enemy in real time using an unmanned surveillance device, of checking a current status within a short time by wirelessly and simultaneously transmitting the checked information to a decision maker, a person in charge of an operational force, etc., and of accurately checking the status of an operational area before the operational force is deployed in combat based on wireless control of an unmanned security system by the decision maker or the like. A closed-circuit television (CCTV), which is an unmanned surveillance device commonly used in daily life, directly transmits a signal using a cable and does not externally transmit a radio signal. Unlike a general broadcasting system for transmitting a radio signal receivable by anyone, the CCTV, as the name implies, transmits an image only to a cable-connected device of a certain person. 
     However, image information obtainable by merely installing a camera on a pole and moving the camera in vertical and horizontal directions is very restrictive and is very vulnerable to fog, nighttime, and rain.

       FIG. 1  is a conceptual view of an ICT-based unmanned security system according to an embodiment of the present invention,  FIG. 2  is a conceptual view of unmanned surveillance devices and mobile devices of the ICT-based unmanned security system according to an embodiment of the present invention, and  FIG. 3  is a front view of an intruder surveillance device. 
     As illustrated in  FIGS. 1 to 3 , the ICT-based unmanned security system according to an embodiment of the present invention includes an unmanned surveillance device  20  and a mobile device  50 . The unmanned surveillance device  20  not only provides photos and text messages to a surveillant immediately after an intruder enters but also issues a warning to the intruder by shining a light on the intruder, based on cooperation between an information collection unit  10  configured as an intelligent sensor such as a fusion sensor, an Internet protocol (IP) camera  13 , and a light-emitting means  40  configured as a light-emitting diode (LED) or the like. Preferably, the fusion sensor which is an intelligent sensor serving as a core element of the unmanned surveillance device  20  includes one microwave sensor (radar sensor) capable of accurately detecting the size and motion of an object, and two thermal infrared sensors capable of sensitively detecting temperature variation. The unmanned surveillance device  20  has embedded software and a high-performance microchip and a variety of motion patterns of people and animals are stored in the sensors. That is, a person in a control room does not watch a closed-circuit television (CCTV) monitor to detect intrusion and, instead, a first controller  30  autonomously determines an intruder if an object over 40 kg moves at 0.1 meter per second (m/s) or faster. When the unmanned surveillance device  20  was installed and tested, a detection range thereof was up to 200 m on flat land and from 15 to 35 m on a slope, and an intruder detection rate was over 99%. 
     The unmanned surveillance device  20  includes the information collection unit  10 , a surveillance device wireless communication unit  33 , and the first controller  30 , and the first controller  30  includes a determination unit  31  and a warning controller  32 . The surveillance device wireless communication unit  33  may wirelessly transmit and receive information through a fourth-generation (4G) long term evolution (LTE) network  60  using LTE communication. Although a wireless communication method using a 4G LTE network is described as an example in the present invention, other wireless communication methods are also usable. The first controller  30  may control all the other elements included in the unmanned surveillance device  20 . The first controller  30  may transmit peripheral status information collected by the information collection unit  10 , through the surveillance device wireless communication unit  33 . 
     When the mobile device  50  transmits a remote control signal through a mobile device wireless communication unit using LTE communication, the first controller  30  may receive the remote control signal through the surveillance device wireless communication unit  33 , and drive the unmanned surveillance device  20  based on the received remote control signal. 
     When a plurality of mobile devices  50  are present, the first controller  30  may wirelessly and simultaneously transmit the collected peripheral status information to the plurality of mobile devices  50  using LTE communication. As such, a plurality of administrators or the like may simultaneously check the collected peripheral status information. 
     The mobile device  50  includes the mobile device wireless communication unit  51 , a display unit  52 , and a second controller  53 . The mobile device  50  may refer to all mobile devices capable of transmitting and receiving information using LTE communication, e.g., a mobile phone, smartphone, notebook computer, digital multimedia broadcasting (DMB) receiver, personal digital assistant (PDA), portable multimedia player (PMP), and navigation system. 
     The mobile device wireless communication unit  51  may wirelessly transmit and receive information through the 4G LTE network  60  using LTE communication. 
     The display unit  52  may display (output) information processed by the mobile device  50 . For example, the display unit  52  may include at least one selected from among a liquid crystal display (LCD), thin film transistor-liquid crystal display (TFT LCD), organic light-emitting diode (OLED), flexible display, and three-dimensional (3D) display. 
     The second controller  53  may wirelessly receive the peripheral status information from the unmanned surveillance device  20  through the mobile device wireless communication unit  51 , and display the peripheral status information on the display unit  52 . 
     When a remote control signal for controlling the unmanned surveillance device  20  is input through a user input unit (not shown) such as a keypad, mouse, or touchscreen, the second controller  53  transmits the remote control signal to the unmanned surveillance device  20  through the mobile device wireless communication unit  51 . The remote control signal is a signal for controlling operation of the unmanned surveillance device  20 . For example, the remote control signal may be a signal for controlling motion, power, information transmission, etc. of the unmanned surveillance device  20 . 
     As illustrated in  FIG. 2 , the unmanned surveillance device  20  may be configured in various forms, e.g., an unmanned reconnaissance aircraft  24 , an unmanned intelligent flying robot  23 , an unmanned camera  22 , and a detection sensor  21 . Each unmanned surveillance device  20  may include an information collection unit, a wireless communication unit, and a controller. 
     The mobile device  50  includes all mobile devices capable of transmitting and receiving information using LTE communication, e.g., a mobile phone, smartphone, notebook computer, DMB receiver, PDA, PMP, and navigation system. 
     When a remote control signal for controlling the unmanned surveillance device  20  is input through a user input unit (not shown), the mobile device  50  transmits the remote control signal to the unmanned surveillance device  20  through a wireless communication unit (not shown) for a mobile device. The remote control signal is a signal for controlling operation of the unmanned surveillance device  20 . 
     When the remote control signal is received through the wireless communication unit (not shown) for a mobile device, the unmanned surveillance device  20  may operate based on the received remote control signal. For example, if the remote control signal is a signal for moving the unmanned intelligent flying robot  23 , the controller of the unmanned intelligent flying robot  23  controls the unmanned intelligent flying robot  23  to move to a certain area based on the remote control signal. As such, a user of a mobile device (e.g., a person in charge of reconnaissance) may remotely control a surveillance device to monitor a desired area, using the mobile device. As such, an administrator or the like may check information in real time and instantaneously issue an instruction to monitor a desired area. 
     As illustrated in  FIGS. 1 and 3 , the unmanned surveillance device  20  includes a body  2  having a pole shape standing on the ground, and a wind power generator  82 , a solar power generator  81 , the information collection unit  10  configured as the fusion sensor, and the light-emitting means  40 , which are mounted on the body  2 . 
     The body  2  may be configured in a pole shape standing on the ground, and the shape thereof may be variously changed depending on an installation location thereof. When the unmanned reconnaissance aircraft  24 , the unmanned intelligent flying robot  23 , the unmanned camera  22 , or the detection sensor  21  is used as the unmanned surveillance device  20  as described above, the shape of the body  2  may be correspondingly changed. 
     The solar power generator  81  and the wind power generator  82  for configuring a power source  80  autonomously generate and supply electricity required to operate the mounted parts. As such, connection of power and communication cables is not necessary and a wild animal control system may be independently installed. 
     The unmanned security system includes the first controller for determining whether an intruder enters a surveillance area, the light-emitting means  40 , the mobile device  50 , the 4G LTE network  60 , and the power source  80 . 
     The unmanned surveillance device  20  may determine whether an intruder enters a surveillance area, and transmit intrusion information to a user or let the intruder out of the surveillance area. The unmanned surveillance device  20  includes the information collection unit  10  configured as the fusion sensor in which a radar  11  and an infrared sensor  12  for detecting infrared light emitted from an intruder are combined. Additionally, the information collection unit  10  may include the camera  13  for photographing an object. The camera  13  may be integrated with or separated from the fusion sensor configured as the information collection unit  10 . The radar  11  included in the fusion sensor excels at detecting the size and motion of every object and is useful in terms of detection speed and detection size but is not useful in terms of temperature, but the thermal infrared sensor  12  for sensing motion of an object by detecting infrared light emitted from a person or animal is useful in terms of temperature and is not useful in terms of detection speed. Therefore, the fusion sensor obtained by combining the two sensors uses only advantages of each sensor to improve the performance thereof, and thus a problem such as detection failure or false detection rarely occurs. The numbers of the radars  11  and the thermal infrared sensors  12  may be selectively set by the user depending on an environment of the surveillance area. The camera  13  is a smart IP camera and is capable of capturing an image of 1,000,000 to 10,000,000 pixels (preferably 1,000,000 pixels), and a frame rate is preferably 1 to 30 frames per second (fps). Like a CC camera, the camera  13  has a driving device embedded therein to rotate by up to 355°, and has a record function and a bidirectional audio function. Additionally, an external motion sensor may be mounted on the smart IP camera. In the present invention, one radar  11  and two infrared sensors  12  are combined and are interlocked to operate in a harsh outdoor environment, and the embedded software is used to verify a detected object by comparing a motion pattern of an intruder and thermal infrared light emitted therefrom, thereby maximizing reliability. 
     The unmanned surveillance device  20  includes the first controller  30  for receiving a signal detected by the information collection unit  10  configured as the fusion sensor, determining whether the detection object is an intruder, and generating a control signal if the detection object is an intruder. The first controller  30  may be integrally included in the unmanned surveillance device  20  as illustrated in  FIG. 1 , or may be included a control server. The first controller  30  may determine whether a detected object is an intruder, by comparing the detected information 
     to an intruder determination criterion preset in the fusion sensor using the embedded software and an algorithm of the high-performance microchip integrally configured in the fusion sensor. That is, preferably, the first controller  30  is integrally included in the information collection unit  10 . In particular, the sensors are interlocked using the algorithm and the embedded software to operate in a harsh outdoor environment, and a detected object is verified by comparing a motion pattern of an intruder and thermal infrared light emitted therefrom, thereby maximizing reliability. Specifically, malfunction in the natural environment or motion of an object is distinguished and thus the highest reliability is ensured. 
     The first controller  30  includes the determination unit  31  for receiving a detection signal and image of the information collection unit  10 , and the warning controller  32  for controlling emission of the light-emitting means  40 . Although the first controller  30  includes the determination unit  31 , the warning controller  32 , and the surveillance device wireless communication unit  33  in the present invention, the first controller  30  may be integrally included in the information collection unit  10  configured as the fusion sensor, and the fusion sensor may directly determine whether the detected object is an intruder using the algorithm and the embedded software. 
     The information collection unit  10  collects the peripheral status information using images or detection signals generated by the radar, the infrared sensors, and the camera, and transmits the peripheral status information collected by the information collection unit  10  to the determination unit  31 . The determination unit  31  determines whether the detected object is an intruder, based on the collected information. Based on the intruder determination criterion preset in the determination unit  31 , if an object over 40 kg moves at 0.1 m/s or faster, the object is determined to be an intruder. The weight and speed values may be changed as desired by the user. When an outline of the object is obtained by the radar and the infrared sensors, a volume thereof is converted into a total weight. 
     If the detected object is determined to be an intruder, the warning controller  32  turns on the light-emitting means  40  by controlling emission thereof. When the light-emitting means  40  is turned on, light is emitted and a warning message is provided to the intruder by the light. In addition, if the detected object is determined to be an intruder, the warning controller  32  stores an image of the intruder, which is captured by the camera  13 , in a storage  13   c  as a file and operates a speaker  13   b  and a microphone  13   a  included in the camera  13 . Warning sound may be output through the speaker  13   b , and a voice message input by the user through the mobile device  50  may be output through the speaker  13   b.    
     If the intruder is not as a person but a wild animal and the unmanned security system is used as a wild animal control system, the warning controller  32  counts the number of times that the determination unit  31  determines wild animals, per time zone, and calculates a time zone when wild animals often appear. The luminance of light emitted from the light-emitting means  40  in the time zone when wild animals often appear is set to be higher than the luminance of light emitted in the other time zones, thereby increasing the effect of keeping wild animals away. Alternatively, the number of times that the light-emitting means  40  emits light may be increased in the time zone when wild animals often appear. For example, light of the same luminance may be repeatedly emitted twice or more whenever a wild animal is detected once, thereby increasing the effect of keeping wild animals away. 
     The mobile device  50  includes the mobile device wireless communication unit  51  for wirelessly transmitting and receiving information to the surveillance device wireless communication unit  33  using LTE communication, and the display unit  52  for displaying the peripheral status information received through the mobile device wireless communication unit  51 , to be viewed by the user. The mobile device  50  further includes the second controller  53  for generating a control signal for controlling the light-emitting means  40  by the user based on the image information displayed on the display unit  52 , and the control signal generated by the second controller  53  is transmitted to the surveillance device wireless communication unit  33  though the mobile device wireless communication unit  51 . The control signal received by the surveillance device wireless communication unit  33  is transmitted to the warning controller  32 , and operation of the light-emitting means  40  is controlled based on the control signal. 
     When a plurality of mobile devices  50  are present, the wild animal surveillance device  20  may wirelessly and simultaneously transmit the collected peripheral status information to the plurality of mobile devices  50  using LTE communication. 
     The display unit  52  may display (output) information processed by the mobile device  50 . For example, the display unit  52  may include at least one selected from among an LCD, TFT LCD, OLED, flexible display, and 3D display. 
     When a remote control signal for controlling the unmanned surveillance device  20  is input through a user input unit (not shown) such as a keypad, mouse, or touchscreen, the second controller  53  of the mobile device  50  transmits the remote control signal to the surveillance device wireless communication unit  33  of the unmanned surveillance device through the mobile device wireless communication unit  51 . The remote control signal is a signal for controlling operation of the unmanned surveillance device  20 . For example, the remote control signal may be a signal for controlling motion, power, information transmission, etc. of the unmanned surveillance device  20 . 
     Since an ICT-based unmanned surveillance device operates in a wireless manner, large-scale foundation work for installing a wired system may not be required and maintenance costs of the wired system may be reduced. In addition, since an ICT-based wild animal surveillance device is configured to be mobile, information may be obtained in real time while moving and the unmanned surveillance device  20  may be instantaneously and remotely controlled, thereby reducing a reaction time required to displace wild animals. 
     Preferably, the light-emitting means  40  is configured as a high-luminance LED searchlight. Although the light-emitting means  40  operates at about 55W, light is focused at a beam angle of 6° or less and proceeds 300 m or more and the user may accurately target the light on the eyes of a boar while monitoring the mobile device  50 . 
     The light-emitting means  40  may be integrated with or separated from the wild animal surveillance device  20 . When the light-emitting means  40  is separated from the wild animal surveillance device  20 , a cable connection may be established therebetween to transmit and receive an operation signal. 
     The unmanned surveillance device  20  includes the solar power generator  81  for generating electricity required to operate the system using solar energy and storing the electricity. The solar power generator  81  includes a solar panel for absorbing sunlight to convert light energy into electricity, and a charger for charging the electricity generated by the solar panel, in a battery. The electricity charged in the charger of the solar power generator  81  is used to supply electricity required to operate each element of the system. In the ICT-based unmanned security system, since the light-emitting means operates only if a signal detected by the unmanned surveillance device  20  indicates an intruder, power consumption is low and thus electricity may be sufficiently supplied by only the solar power generator  81 . 
     Although not shown in the drawings, the present invention may supply electricity using a power generator other than the solar power generator  81  and the wind power generator  82 , by connecting an additional battery, or by connecting an external power cable. 
     An operation process of the above-described ICT-based unmanned security system according to the first embodiment of the present invention is as described below. 
     When an intruder appears in a surveillance area, the fusion sensor including the radar  11 , the infrared sensors  12 , and the camera  13  detects the intruder. A signal detected by the information collection unit  10  configured as the fusion sensor is transmitted to the first controller  30 . The signal transmitted to the first controller  30  is stored, and the stored signal is transmitted to the determination unit  31  to determine whether the transmitted information indicates an intruder. If the determination unit  31  determines that the captured image signal indicates an intruder, the surveillance device wireless communication unit  33  transmits the signal to the mobile device wireless communication unit  51  of the mobile device  50  using the 4G LTE network  60 . In this case, the mobile device  50  sounds a detection alarm, receives a message, and displays the image signal received through the mobile device wireless communication unit  51  on the display unit  52 . 
     The user checks the image displayed on the display unit  52  and generates a control signal for automatically or manually operating the light-emitting means  40 . The generated control signal is transmitted to the surveillance device wireless communication unit  33  through the mobile device wireless communication unit  51 , and the control signal transmitted to the surveillance device wireless communication unit  33  is transmitted to the warning controller  32  to operate the light-emitting means to emit light or operate the speaker  13   b  to output warning sound. 
     In some cases, if the determination unit  31  determines that the captured image indicates an intruder, a control signal may be instantaneously transmitted to the warning controller  32  to control the light-emitting means  40  to emit light. A process from when the fusion sensor captures the image to when the light-emitting means  40  emits light may be monitored by the user on the display unit  52  of the mobile device  50 . In this case, if the user desires, the mobile device  50  may manually generate a control signal to control the light-emitting means  40  to emit light using a wireless communication method. 
     For example, the ICT-based unmanned security system may be used as a wild animal control system particularly for boars. It is reported that boars habitually move a lot around 5:00, 18:00 to 19:00, and 23:00. To improve the efficiency of keeping boars away in these time zones when boars often appear, the warning controller  32  may count the number of times that a detection signal is generated, per time zone to calculate a time zone when wild animals often appear, and may control the light-emitting means  40  to emit light of a higher luminance or emit light a larger number of times in the time zone when wild animals often appear, compared to the other time zones. 
       FIG. 4  is a front view of a camera of an unmanned security system according to another embodiment of the present invention. In the unmanned security system according to another embodiment of the present invention, as illustrated in  FIG. 4 , a composite hinge  90  capable of rotating horizontally and vertically is mounted on a certain part of the body  2 , and the camera  13  and the light-emitting means  40  are mounted on the composite hinge  90 . 
     The composite hinge  90  includes a fixed part  91  fixed to the certain part of the body  2 , a first rotatable part  92  rotatably mounted on the fixed part  91 , and a second rotatable part  93  rotatably mounted on the first rotatable part  92  to rotate about a rotation axis crossing the rotation axis of the first rotatable part  92 . A motor (not shown) for generating rotational force of the first and second rotatable parts  92  and  93  by receiving a signal of a controller is mounted on the first and second rotatable parts  92  and  93 . 
     By rotating the first and second rotatable parts  92  and  93  based on the location of an intruder, wherever the intruder appears, the camera  13  and the light-emitting means  40  are driven to face the intruder. To this end, the composite hinge  90  may operate by receiving a control signal for issuing an instruction to move toward the location of the intruder based on information detected by the first controller  30 , or by receiving a control signal input to the mobile device  50  by a user. The structure in which the camera  13  and the light-emitting means  40  are mounted on the composite hinge  90  may be variously changed as in the previous embodiment of the present invention. 
     As described above, the ICT-based unmanned security system according to the present invention may receive a detection signal not using a wireless communication method but using a cable depending on an installation location thereof. That is, a plurality of unmanned surveillance devices  20  may be installed within a sightline distance of 1 km, a detection signal received therefrom may be transmitted to the mobile device  50  such as a smartphone, and the light-emitting means  40  may automatically follow and emit light to a detected object. 
     The unmanned surveillance device  20  autonomously identifies a wild animal and wirelessly transmits the identification information. Since the unmanned surveillance device  20  merely determines whether an animal is detected and wirelessly transmits the animal detection information, the unmanned surveillance device  20  may be easily installed at a place where wild animals appear. When the detection signal is transmitted to the camera  13 , the camera  13  automatically moves toward the detected location and then the light-emitting means  40  automatically turns on an LED searchlight. 
     As a structure using the Internet of things (IoT), the radar sensor and the thermal infrared sensors for configuring the information collection unit  10  of the unmanned surveillance device  20  cooperate to autonomously detect an animal or person based on the size, motion, and motion pattern thereof, and to autonomously and automatically notify the user through the Internet, the camera  13  moves and automatically performs a recording operation, and the light-emitting means  40  automatically emits light. Through the Internet, the light-emitting means  40  may be turned on/off and the speaker  13   b  may output sound that wild animals dislike or output a voice signal of the user. 
     The light-emitting means  40  may be integrally attached to sides of the camera  13 . 
     A sensor included in the information collection unit  10  has a detectable range of 15 m when mounted at a height equal to or less than 1.2 m, has a detectable range of 35 m when mounted at a height of 3 to 4 m, and has a detectable range of 200 m when mounted at a height of 1 m. 
     In addition, a telecommunication cable may not be installed in consideration of a harsh outdoor environment and the unmanned surveillance device  20  may autonomously ignore insignificant objects and detect and displace only an intruder having a size greater than a preset size using IoT and ICT technology. For example, since a boar has a weight of about 100 to 300 kg, if only objects over 80 kg are detected, only boars may be displaced without causing a false alarm. 
     Although the unmanned surveillance device  20  for detecting an intruder is currently configured to detect a size corresponding to 40 kg or above, a desired size may be set. That is, to detect elks, the data set in the determination unit  31  may be changed in consideration of the size of elks. 
     While the present invention has been particularly shown and described with reference to embodiments thereof, it will be understood by one of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
