A monitoring area monitoring system is disclosed. This system includes a monitoring device (fixed monitoring device and in-vehicle monitoring device), a monitoring center, and a user terminal. The fixed monitoring apparatus executes monitoring processing using the captured video, and when a suspicious person is detected, transmits a suspicious person information request message including the feature amount. When the in-vehicle monitoring device receives the suspicious person information request message and stores an image including a suspicious person having a feature quantity similar to the received characteristic quantity, the in-vehicle monitoring apparatus extracts a part including the suspicious person, The information response message is transmitted to the fixed monitoring device. By not transmitting an image that does not include a suspicious person, it is difficult to tighten the communication band of the communication path when transmitting the suspicious person information response message.

Power is supplied from the car battery 114 to the plurality of first to Nth sensors.

  In response to the request from the server 102 received by the packet receiving unit 164, the activation control unit 160 controls activation / deactivation of the first to Nth sensors. At this time, the activation control unit 160 acquires information on the remaining battery level from the car battery 114, and controls the first to Nth sensors in consideration of the remaining battery level. If the remaining battery level is not sufficient, a predetermined code (hereinafter, an incompatible code) indicating that the battery cannot be handled is transmitted to the server 102. In addition, when the vehicle 108 enters a predetermined state (for example, when parked), the activation control unit 160 stores the vehicle position information and a predetermined code (hereinafter referred to as a P code) indicating that the vehicle 108 is in the predetermined state. The packet is transmitted to the packet 102 via the packet transmission unit 166. The vehicle position information is acquired by a known method (for example, reception of a GPS signal).

  A detection signal of each sensor of the sensor device 112 is acquired as sensor information by the sensor information collection unit 162. The function of the sensor information collection unit 162 is realized by, for example, the I / F unit 124 and the memory 128 of FIG. The output signals of the first to Nth sensors are stored in the memory 128 as digital data in a format corresponding to the sensor.

The server 102 also receives sensor information uploaded from the in-vehicle devices of vehicles other than the vehicle 108 and analyzes it for monitoring purposes.

  The packet receiving unit 164 receives and demodulates radio waves, and generates packet data. When the received packet data includes a request from the server 102, the packet receiving unit 164 transmits the request to the activation control unit 160. As described above, the request from the server 102 is used for controlling the first to Nth sensors by the activation control unit 160. Other packet data is appropriately stored in the memory 128 and used by the operation system or another application program. The packet receiving unit 164 is realized by, for example, the communication unit 126 in FIG.

[Functional configuration of server]
The function of the server 102 will be described with reference to FIG. The server 102 includes a packet receiving unit 180 that receives packet data, a packet transmitting unit 182 that transmits packet data, an analysis processing unit 184 that performs predetermined analysis processing on received data (sensor information), and an analysis result And a management unit 186 to which received data is input, and a warning unit 188 that outputs a warning to the outside (registered user, security company, etc.) under the control of the management unit 186. The warning unit 188 may transmit a warning via the packet transmission unit 182.

  When the packet receiving unit 180 receives packet data including sensor information transmitted from the in-vehicle device 120 and the infrastructure sensor 106 of the vehicle 108, the packet receiving unit 180 inputs the received data to the analysis processing unit 184 and the management unit 186. The function of the packet receiving unit 180 is realized by the communication unit 144 and the memory 142 of FIG.

  The analysis processing unit 184 performs an analysis process on the sensor information included in the input packet data in order to detect a suspicious situation. The suspicious situation means a situation where there is a person who performs a suspicious action (suspicious person), a situation where an action that is likely to cause damage or harm is being performed, and the like. For the analysis processing, known object detection processing and feature amount extraction processing can be used. For example, the movement information (speed, continuous movement time, movement of detected results) (including people) can be used. Stability, etc.) can be obtained and the degree of suspiciousness can be obtained. The suspicious degree is preferably determined in consideration of the time zone. For example, when the movement is detected, it is preferable that the suspicious degree is set higher in the time zone of the midnight (eg, from 10:00 pm to 5:00 am the next day) than the other time zones. For example, the suspicious degree can be calculated based on an accumulated time during which a detected person continuously moves around a vehicle or the like in a predetermined time zone such as at night. The analysis processing unit 184 inputs the analysis result (including the suspicious degree) of the sensor information to the management unit 186 together with the transmission source information of the sensor information. The analysis processing unit 184 is realized by, for example, the control unit 140 in FIG. The server 102 may include dedicated hardware (circuit board, ASIC, etc.) for the analysis processing unit 184.

  The management unit 186 holds information for specifying the monitoring area (for example, map information) and the position information of the infrastructure sensor 106, and if the received packet data includes position information and a P code, the information is specified by the position information. It is determined whether or not the position to be detected is different from the position of the infrastructure sensor 106 and whether or not it is within the monitoring area. Unlike the position of the infrastructure sensor 106, if it is outside the monitoring area, the management unit 186 transmits a predetermined code (hereinafter referred to as a request code) via the packet transmission unit 182 in order to obtain sensor information.

  In addition, when the analysis result and the transmission source information are input from the analysis processing unit 184, the management unit 186 determines whether or not there is a suspicious situation. For example, the management unit 186 determines whether there is a suspicious situation based on the suspicious degree. If it is clear that the situation is suspicious, the management unit 186 inputs a predetermined instruction to the warning unit 188 (reports to a security company or the like). When the transmission source information input from the analysis processing unit 184 is different from the transmission destination of the request code, it is a result of analyzing the sensor information received from the infrastructure sensor 106. Therefore, the management unit 186 determines a predetermined value according to the analysis result. Execute the process. If the transmission source information is the same as the transmission destination of the request code and cannot be determined as a suspicious situation, the management unit 186 further requests sensor information from the in-vehicle device. That is, packet data including a predetermined code (hereinafter referred to as an addition request code) and including the transmission source information input from the analysis processing unit 184 as transmission destination information is transmitted via the packet transmission unit 182. The management unit 186 is realized by, for example, the control unit 140 in FIG.

  The warning unit 188 receives an instruction from the management unit 186 as described above and outputs information to the outside. For example, the warning unit 188 reports a warning to a security company, a registered user of the monitoring system 100, or the like.

[Operation]
The operation of the monitoring system 100 will be described by describing the operations of the in-vehicle device 120 and the server 102 of the vehicle 108 with reference to FIGS. 6 and 7. The processing shown in FIG. 6 is realized by the control unit 130 reading a predetermined program from the memory 128 and executing it. Here, it is assumed that when the parking brake (parking brake, side brake) of the vehicle 108 is set, the control unit 130 starts executing the program on the assumption that parking is started. The processing shown in FIG. 7 is realized by the control unit 140 reading a predetermined program from the memory 142 and executing it.

[Operation of in-vehicle device]
Referring to FIG. 6, in step 300, control unit 130 transmits the position information of vehicle 108 to server 102 via packet transmission unit 166 together with a P code indicating that the parking brake is set. Thereafter, control proceeds to step 302.

  In step 302, the control unit 130 determines whether or not the packet reception unit 164 has received a request code for requesting sensor information from the server 102. If it is determined that it has been received, control proceeds to step 304. Otherwise, step 302 is repeated.

  In step 304, the control unit 130 acquires information on the remaining battery level from the car battery 114, and determines whether the remaining battery level is equal to or greater than a predetermined value (hereinafter referred to as a steady monitoring threshold) X1. If it is equal to or greater than the steady monitoring threshold value X1, control proceeds to step 306. Otherwise, control passes to step 310. As will be described later, the steady monitoring threshold value X1 is set to a value that does not cause any trouble even if the power stored in the car battery 114 is consumed by maintaining the state for a predetermined time. For example, the value is set so as not to cause a situation where the engine cannot be started, a situation where software of the in-vehicle IC (microcomputer or the like) cannot be automatically updated, or a situation where communication with the outside of the vehicle cannot be performed. The steady monitoring threshold value X1 can be set in advance based on, for example, the product pw1 × h1 of the power consumption pw1 of the sensor to be activated and the expected monitoring time h1.

  In step 306, the control unit 130 activates the first sensor. This is a function of the activation control unit 160 in FIG. Thereafter, control proceeds to step 308. Since step 306 can be repeatedly executed, if the first sensor has already been activated, the control unit 130 does not execute the activation process. Which of the plurality of sensors is the first sensor may be set in advance in consideration of at least one of the detection range and the power consumption. The first sensor preferably has a wide detection range and low power consumption. For example, a laser radar that has a wide detection range and can detect 360 degrees can be used as the first sensor. If a sensor with lower power consumption is used as the first sensor, the vehicle 108 can suppress battery consumption due to the operation of the sensor, and a sensor with a wider detection range (for example, some that can detect 360 degrees). If the laser radar is used as the first sensor, the server 102 can monitor a wider range of the non-monitoring area. If the camera can be used, the server 102 can acquire more detailed sensor information.

  In step 308, the control unit 130 acquires sensor information from the first sensor activated in step 306 and transmits the sensor information to the server 102. This is a function of the sensor information collection unit 162 of FIG. Thereafter, control proceeds to step 312. As will be described later, when the sensor information is transmitted, the control unit 130 acquires the current time and stores the current time in a predetermined area of the memory 128 as a reference time so that the process can be repeated each time a predetermined time elapses. Remember. The current time may be acquired from a timer mounted on the vehicle 108 or may be acquired by receiving a GPS signal.

  On the other hand, if the remaining battery level is less than the steady-state monitoring threshold value X1 (the determination result in step 304 is NO), in step 310, the control unit 130 indicates that it cannot respond to the request from the server 102. The impossible code is transmitted to the server 102. If the first sensor is activated in step 306, the control unit 130 stops the first sensor, and then the program ends.

  In step 312, the control unit 130 determines whether a request for further sensor information has been received from the server 102. Specifically, the control unit 130 determines whether or not packet data including an addition request code has been received from the server 102 via the packet receiving unit 164. If it is determined that it has been received, control proceeds to step 314. Otherwise, control passes to step 326.

  In step 314, the control unit 130 acquires information on the remaining battery level from the car battery 114, and determines whether the remaining battery level is equal to or greater than a predetermined value (hereinafter referred to as a detailed monitoring threshold) X2. If it is greater than or equal to the detail monitoring threshold value X2, control proceeds to step 316. Otherwise control passes to step 320. As will be described later, since the first sensor is stopped when the second sensor is activated, the detailed monitoring threshold value X2 is consumed by the stored power of the car battery 114 when the second sensor is activated for a predetermined time. It is set to a value that does not cause any trouble. For example, the value is set so as not to cause a situation where the engine cannot be started, a situation where software of the in-vehicle IC (microcomputer or the like) cannot be automatically updated, or a situation where communication with the outside of the vehicle cannot be performed. The detailed monitoring threshold value X2 can be preset based on, for example, the product pW2 × h2 of the power consumption pw2 of the sensor to be activated and the expected monitoring time h2.

  In step 316, the control unit 130 activates the second sensor, and stops the first sensor activated in step 306. This is a function of the activation control unit 160 in FIG. Thereafter, control proceeds to step 318. Since step 316 can be repeatedly executed, if the second sensor has already been activated, the control unit 130 does not execute the activation process. Which of the plurality of sensors is the second sensor may be set in advance in consideration of the detection range and power consumption. The second sensor is preferably one that can acquire more detailed sensor information than the first sensor and consumes less power. For example, a digital camera that can acquire a color image is preferably used as the second sensor.

  In step 318, the control unit 130 acquires sensor information from the second sensor activated in step 316 and transmits the sensor information to the server 102. This is a function of the sensor information collection unit 162 of FIG. Thereafter, control proceeds to step 322. As will be described later, when the sensor information is transmitted, the control unit 130 acquires the current time and stores the current time in a predetermined area of the memory 128 as a reference time so that the process can be repeated each time a predetermined time elapses. Remember.

  On the other hand, if the remaining battery level is less than the detailed monitoring threshold value X2 (the determination result in step 314 is NO), in step 320, the control unit 130 indicates that it cannot respond to the request from the server 102. The impossible code is transmitted to the server 102. Thereafter, control returns to step 304.

  In step 322, the control unit 130 determines whether or not an end instruction has been received. If it is determined that an end instruction has been received, the control unit 130 stops the activated second sensor, and then the program ends. Otherwise control passes to step 324. The end instruction is given, for example, when the engine of the vehicle 108 is started.

  In step 324, the control unit 130 determines whether or not a predetermined time has elapsed since the sensor information was transmitted in step 318. The control unit 130 acquires the current time and compares it with the reference time stored in step 318 to determine whether or not a predetermined time has elapsed. If it is determined that the predetermined time has elapsed, control returns to step 314. Otherwise, control returns to 322. The predetermined time may be set in advance in units of seconds, minutes, or the like.

  On the other hand, if the addition request code has not been received (the determination result in step 312 is NO), in step 326, the control unit 130 determines whether or not an end instruction has been received. When it is determined that the termination instruction has been received, the control unit 130 stops the activated first sensor, and then the program ends. Otherwise control passes to step 328.

  In step 328, the control unit 130 determines whether or not a predetermined time has elapsed since the sensor information was transmitted in step 308. The control unit 130 acquires the current time and compares it with the reference time stored in step 308 to determine whether a predetermined time has elapsed. If it is determined that the predetermined time has elapsed, control returns to step 304. Otherwise, control returns to 326. The predetermined time may be set in advance in units of seconds, minutes, or the like.

  As described above, the in-vehicle device 120 transmits the position information of the vehicle 108 to the server 102 when the vehicle 108 is parked. If the position specified by the received position information is outside the monitoring area, the server 102 requests sensor information from the in-vehicle device 120 (transmits a request code). In-vehicle device 120 receives the request from server 102 (reception of the request code in step 302), and if the remaining battery level is sufficient, activates the first sensor, acquires sensor information, and transmits it to server 102. To do. As a result, the server 102 can analyze the received sensor information and determine whether there is a suspicious situation outside the monitoring area. If necessary (for example, when it cannot be determined as a suspicious situation), the server 102 can request the in-vehicle device 120 to transmit more detailed sensor information (transmission of an additional request code). If there is a request for further sensor information from the server 102 (reception of an additional request code in step 312), the in-vehicle device 120 activates the second sensor to acquire sensor information if the remaining battery level is sufficient, Send to server 102. Thereby, the server 102 can analyze the received sensor information and more accurately determine whether or not there is a suspicious situation outside the monitoring area.

  In addition, even if the in-vehicle device 120 receives the request code and the remaining battery level is not sufficient (NO in step 304), the in-vehicle device 120 can transmit an incompatible code to the server 102. It is possible to avoid the trouble of the original function of 108. In addition, even if the in-vehicle device 120 receives the addition request code, if the remaining battery level is not sufficient (NO in step 314), the incapable code can be transmitted to the server 102, so that the sensor information of the first sensor is obtained. While maintaining the transmission to the server 102, it is possible to avoid the trouble of the original function of the vehicle 108 due to the power consumption of the car battery 114. Further, when the server 102 receives the incapable code from the in-vehicle device 120 that has transmitted the addition request code, the server 102 can acquire the more detailed sensor information by transmitting the additional request code to the in-vehicle device of another vehicle. It is possible to more accurately determine whether there is a suspicious situation outside the monitoring area.

[Server operation]
Referring to FIG. 7, in step 400, control unit 140 specifies a monitoring target area from the detection range and installation position of infrastructure sensor 106 used for monitoring, and stores the information (map information, etc.) in memory 142. To do.

  In step 402, the control unit 140 determines whether or not position information of a parked vehicle has been received. Specifically, the control unit 140 determines whether or not the in-vehicle device 120 has received the packet data including the position information and the P code transmitted in step 300. If it is determined that the packet data including the position information and the P code has been received, the control proceeds to step 404. Otherwise, control passes to step 408.

  In step 404, the control unit 140 determines whether or not the position specified by the position information received in step 402 is outside the monitoring area specified in step 400. If it is determined that the area is out of the monitoring area, the control proceeds to step 406. Otherwise, control passes to step 434.

  In step 406, the control unit 140 stores the position information received in step 402 and the transmission source information (transmission source information included in the packet data) in association with each other in the memory 142, and generates a request code for requesting sensor information. The included packet data (using the transmission source information stored in the memory 142 as the transmission destination information) is transmitted to the in-vehicle device 120. Thereafter, control proceeds to step 408.

  In step 408, the control unit 140 determines whether an incompatible code has been received. This incompatible code is transmitted by the in-vehicle device 120 in step 310. If it is determined that an incapable code has been received, control proceeds to step 410. Otherwise, control passes to step 412.

  In step 410, the control unit 140 deletes the position information and the transmission source information stored in the memory 142 in step 406. Thereafter, control proceeds to step 412.

  In step 412, the control unit 140 determines whether sensor information has been received. If it is determined that sensor information has been received, control proceeds to step 414. Otherwise, control passes to step 434.

  In step 414, the control unit 140 stores the received sensor information in the memory 142, and executes a predetermined analysis process. This is a function of the analysis processing unit 184 in FIG. Thereafter, control proceeds to step 416.

  In step 416, the control unit 140 determines whether or not a suspicious situation has been detected from the analysis result obtained in step 414. If it is determined that a suspicious situation has been detected, control proceeds to step 418. Otherwise (if it cannot be determined that the situation is suspicious), control proceeds to step 420.

  In step 418, the control unit 140 reports a warning to the outside (security company, registered user, etc.). Thereafter, control proceeds to step 434.

  On the other hand, if it is not clear in step 416 that the situation is suspicious, in step 420, the control unit 140 receives the sensor information analyzed in step 414 from the in-vehicle device of the vehicle located outside the monitoring area. It is determined whether or not there is a possibility of a suspicious situation. If the analysis result is sensor information received from the in-vehicle device of the vehicle located outside the monitoring area and it is determined that there is a possibility of a suspicious situation, the control proceeds to step 422. Otherwise, that is, if the analysis result is the analysis result of the sensor information received from the infrastructure sensor 106 in the monitoring area or it is clear that the situation is not suspicious, the control proceeds to step 434.

  In step 422, the control unit 140 transmits an additional request code for requesting more detailed sensor information to the in-vehicle device that has transmitted the analyzed sensor information. Thereafter, control proceeds to step 424. The control unit 140 uses the corresponding transmission source information stored in the memory 142 in step 406 as the transmission destination information of the addition request code.

  In step 424, the control unit 140 determines whether an incompatible code has been received. This incompatible code is transmitted by the in-vehicle device 120 in step 320. If it is determined that an incapable code has been received, control proceeds to step 426. Otherwise, control passes to step 428.

  In step 426, the control unit 140 transmits an additional request code for requesting detailed sensor information to an in-vehicle device of another vehicle other than the in-vehicle device that has transmitted the analyzed sensor information. Thereafter, control proceeds to step 428. The control unit 140, as the transmission destination information, is the transmission source information stored in the memory 142 in step 406, other than the transmission source information that received the incompatible code in step 414, and has close positional information. Is used. Note that there may be a case where there is no appropriate transmission source information. In this case, an error is displayed, and control may return to step 402. Steps 416 to 426 are functions of the management unit 186 in FIG.

  In step 428, the control unit 140 determines whether sensor information has been received from the in-vehicle device that has transmitted the addition request code. If it is determined that sensor information has been received, control proceeds to step 430. Otherwise, control returns to step 424. Thus, steps 424 to 428 are repeated until sensor information is received from the in-vehicle device that has transmitted the addition request code.

  In step 430, as in step 414, the control unit 140 stores the received sensor information in the memory 142 and executes a predetermined analysis process. Thereafter, control proceeds to step 432.

  In step 432, the control unit 140 executes processing according to the analysis result in step 430. If it becomes clear from the analysis result that the situation is suspicious, the control unit 140 notifies the outside (security company, registered user, etc.) of a warning. If it becomes clear from the analysis result that the situation is not suspicious, the control unit 140 does not report a warning. Thereafter, control proceeds to step 434.

  In step 434, the control unit 140 determines whether an end instruction has been received. If it is determined that an end instruction has been received, the program ends. Otherwise control passes to step 402. The end instruction is given, for example, by receiving an instruction to end the monitoring service.

  As described above, when the server 102 receives the position information from the in-vehicle device (for example, the in-vehicle device 120) of the parked vehicle (for example, the vehicle 108), if the position specified by the received position information is outside the monitoring area, the in-vehicle device. The sensor information can be requested to 120 (a request code is transmitted), and the sensor information detected outside the monitoring area can be received. As a result, the server 102 can analyze the received sensor information and determine whether there is a suspicious situation outside the monitoring area. If necessary (if it cannot be determined that the status is suspicious), the server 102 may request the in-vehicle device 120 to transmit more detailed sensor information (send additional request code) to obtain more detailed sensor information. it can. Further, when the server 102 receives the incapable code from the in-vehicle device 120 that has transmitted the addition request code, the server 102 can acquire the more detailed sensor information by transmitting the additional request code to the in-vehicle device of another vehicle. it can. Accordingly, the server 102 can analyze the sensor information received after the transmission of the addition request code and more accurately determine whether there is a suspicious situation outside the monitoring area.

  The operation of the monitoring system 100 will be described more specifically with reference to FIGS. 8 to 12 (see also FIGS. 6 and 7 as appropriate). 8-12 has shown the residential area typically. Each L-shaped area with a diagonal line and a rectangular area (carport) in contact with the L-shaped area represent a privately owned residential area. The monitoring system 100 identifies the road as the monitoring area 504 based on the detection ranges (ranges with dots) of the monitoring camera 500 and the monitoring camera 502 (step 400). Areas other than the monitoring area 504 are non-monitoring areas. In FIG. 8, the vehicle is not parked in any area.

  Referring to FIG. 9, when vehicle 510 is parked in the non-monitoring area (the parking brake is set), the in-vehicle device of vehicle 510 transmits the position information and P code of vehicle 510 to server 102 (step 300). When the server 102 receives the position information and the P code from the in-vehicle device of the vehicle 510, the server 102 determines whether or not the vehicle 510 is located outside the monitoring area 504 (step 404). Since the vehicle 510 is located outside the monitoring area 504, the server 102 registers information regarding the vehicle 510 and transmits a request code to the in-vehicle device of the vehicle 510. Upon receiving the request code, the in-vehicle device of the vehicle 510 transmits sensor information acquired by activating a laser radar having a detection range of 360 degrees to the server 102 as the first sensor if the remaining battery level is sufficient. . As a result, as shown in FIG. 10, the server 102 can acquire sensor information obtained by sensing the sensor detection area 512 and monitor a non-monitoring area. In FIG. 10, the detection range of the laser radar mounted on the vehicle 510 is shown as a circle. However, since the laser is reflected by an obstacle (such as a wall surface of a house), the back surface of the obstacle is detected. I can't. FIG. 10 shows a vehicle 514 parked in the monitoring area 504. The in-vehicle device of the vehicle 514 also transmits the position information and the P code to the server 102. However, since the vehicle 514 is located in the monitoring area 504, the server 102 does not transmit the request code to the in-vehicle device of the vehicle 514.

  When a person 516 is detected in the sensor detection area 512, sensor information including information on the person 516 is transmitted to the server 102, and it is determined that there is a possibility of a suspicious situation (suspicious person) as a result of executing the analysis process. Then (the determination result in step 420 is YES), the server 102 transmits an addition request code to the in-vehicle device of the vehicle 510. Upon receiving the addition request code, the in-vehicle device of the vehicle 510 activates the digital camera as the second sensor and senses the detailed sensor detection area 518 as shown in FIG. 11 if the remaining battery level is sufficient. The acquired sensor information (high-definition video) is transmitted to the server 102. The server 102 can analyze the movement of the person 516 in more detail based on the received sensor information. If it becomes clear from the analysis result that the situation is suspicious (the person 516 is a suspicious person), the server 102 can warn the security company or the like that there is a suspicious person.

  FIG. 12 shows a state in which vehicles 520 to 526 are parked outside the monitoring area, in addition to the vehicle 510 that is sensing by the laser radar. Similarly to the in-vehicle device of the vehicle 510, the in-vehicle devices of the vehicles 520 to 526 transmit the position information and the P code to the server 102, and receive the request code from the server 102, the first sensor (not limited to the laser radar). The sensor information that is activated and acquired is transmitted to the server 102. Thereby, the server 102 can monitor the non-monitoring area in a wider range. In this manner, the larger the number of vehicles parked in the non-monitoring area, the larger the non-monitoring area can be monitored.

[effect]
In the monitoring system 100, when the server 102 receives position information from the in-vehicle device of the parked vehicle, if the position specified by the received position information is outside the monitoring area by the infrastructure sensor, the server 102 requests the in-vehicle device. Since the sensor information can be received, the monitoring system 100 can monitor a non-monitoring area even temporarily. In addition, when a situation close to a suspicious situation is detected, the server 102 can make an additional request to the in-vehicle sensor of the vehicle parked in the non-monitoring area and receive more detailed sensor information. The system 100 can monitor the non-monitoring area with high accuracy. Therefore, even if infrastructure sensors are not installed in residential areas, parking lots, etc., if a suspicious person is detected in a time zone such as at night when there is little traffic, the security company, registered user, etc. are notified and It is possible to prevent damage from occurring.

  In a vehicle parked in a non-monitoring area, it is determined whether or not to transmit sensor information to the server 102 in consideration of the remaining amount of the car battery. It can be avoided. Further, when the in-vehicle device that has requested the sensor information cannot respond to the request, the server 102 may not be able to monitor by acquiring the sensor information from the in-vehicle device of another vehicle parked in the non-monitoring area. Lower.

(Modification)
In the above description, in step 316 in FIG. 6, the in-vehicle device 120 stops the first sensor when starting the second sensor. However, the present invention is not limited to this. The in-vehicle device 120 may start the second sensor while starting without stopping the first sensor. In that case, what is necessary is just to transmit the sensor information acquired from the 1st sensor and the 2nd sensor to the server 102 in step 318. Thereby, the situation shown in FIG. 11 becomes, for example, as shown in FIG. In FIG. 13, a sensor detection area 512 and a detailed sensor detection area 518 are sensed by a laser radar and a digital camera mounted on the vehicle 510, respectively. At this time, the detailed monitoring threshold value X2 is set to a value that does not cause any trouble even if the stored power of the car battery 114 is consumed by maintaining the state where the first and second sensors are activated for a predetermined time. Is preferred. For example, the detailed monitoring threshold value X2 is based on the product (pw1 + pw2) × h2 of the sum of the power consumption pw1 of the first sensor and the power consumption pw2 of the second sensor (pw1 + pw2) and the expected monitoring time h2. It can be set in advance. Note that since the sensor information obtained from the first sensor and the second sensor is different, the server 102 only needs to execute an analysis process corresponding to each.

  In the above description, the steady monitoring threshold value X1 and the detailed monitoring threshold value X2 have been set in advance, but the present invention is not limited to this. A default value may be set in advance so that the user can change it. Further, the in-vehicle device may learn from the vehicle usage history and the behavior pattern, and the default values of the steady monitoring threshold value X1 and the detailed monitoring threshold value X2 may be changed according to the result.

  In the above description, when the in-vehicle device 120 receives the addition request code from the server 102, it determines whether to activate the second sensor according to the remaining battery level (steps 312 to 320). However, there may be a case where a sensor suitable for monitoring purposes is not provided other than the first sensor. In such a case, the in-vehicle device 120 may transmit an incompatible code to the server 102 without checking the remaining battery level.

  In the above description, the server 102 has the analysis processing unit 184 and analyzes sensor information. However, the present invention is not limited to this. A case where the in-vehicle device 120 includes an analysis processing unit is also conceivable. In such a case, instead of or in addition to transmitting the sensor information to the server 102 and analyzing the sensor information received by the server 102 as described above, the analysis processing unit of the in-vehicle device 120 has the first sensor The sensor information may be analyzed to determine whether there is a suspicious situation. As a result of the analysis, when it is determined that there is a possibility of a suspicious situation, the in-vehicle device 120 may activate the second sensor to acquire detailed sensor information and transmit it to the server 102.

  Moreover, although the case where all the some sensors were supplied with electric power from the car battery 114 was demonstrated above, it is not limited to this. It is conceivable that some sensors have individual batteries. If the individual batteries of the sensors have a standard interface, these sensors can be the target of the remaining battery check by the activation control unit 160. Further, the user may be able to select whether or not a sensor including an individual battery is to be controlled. When the sensor includes an individual battery, the sensor can be activated as necessary without checking the remaining battery level. This is because even if the remaining amount of the individual battery of the sensor runs out, the remaining amount of the car battery is managed as described above, so that the function of the vehicle itself is not hindered.

  In the above description, the case where the vehicle on which the parking brake for the vehicle is set is considered as a parked vehicle and the position information of the vehicle and the P code indicating that the vehicle is parked is transmitted to the server. However, the present invention is not limited thereto. For example, it may be a case where the shift lever of the vehicle is set to the P range (parking range). The case where the state where the parking brake is set continues for a predetermined time (for example, 10 minutes, 30 minutes, etc.) may be used. Alternatively, the engine may be off for a predetermined time or longer.

  Although the case where the parked vehicle of a non-monitoring area was used was demonstrated above, it is not limited to this. A vehicle parked in the non-monitoring area may be used. In addition, even in a non-monitoring area, sensor information obtained by an in-vehicle sensor of a vehicle traveling in the area may be used for monitoring as long as the vehicle is traveling constantly. . In this case, if the in-vehicle device transmits the position information to the server while the vehicle is traveling, the server acquires the sensor information by transmitting a request code to the vehicle traveling in the predetermined non-monitoring area. be able to.

  In the above description, which sensor is activated as the first sensor and the second sensor has been set in the in-vehicle device 120 in advance, but the sensor to be activated may be designated from the server 102. For this purpose, for example, when transmitting the position information and the P-code to the server 102, the in-vehicle device 120 may add and transmit information on the in-vehicle sensor that can be used for monitoring (for example, the type of sensor). When transmitting the request code, the server 102 adds and transmits information for designating the sensor to be activated as the first sensor, and information for designating the sensor to be activated as the second sensor when transmitting the additional request code To be transmitted.

  As mentioned above, although this invention was demonstrated by describing embodiment, above-described embodiment is an illustration, Comprising: This invention is not necessarily restricted only to above-described embodiment. The scope of the present invention is indicated by each claim of the claims after taking into account the description of the detailed description of the invention, and all modifications within the meaning and scope equivalent to the wording described therein are included.
