<1. Overview of Information Collection System According to One Embodiment of the Present Invention>
First, an outline of an information collection system according to an embodiment of the present invention will be described with reference to FIG. FIG. 1 is a diagram for explaining an overview of an information collection system according to an embodiment of the present invention.

  The information collection system includes an information collection device 100 and a communication device 200. The information collection device 100 has a communication function and an information storage function. Further, the communication device 200 is installed in a transportation device and has a communication function, a detection function of a dangerous state of the transportation device, and a function of acquiring position information and status information related to the state of the transportation device when the dangerous state is detected. . Therefore, when the communication apparatus 200 detects the dangerous state of the transport device, the information collecting system can accumulate the position information and the situation information at the position where the dangerous state is detected in the information collecting apparatus 100 via communication. Is possible.

  For example, as illustrated in FIG. 1, the communication device 200A is installed in the vehicle 20A and detects a dangerous state of the vehicle 20A, for example, a closed state of the driver over a long period of time or a sudden braking state. Next, the communication apparatus 200 </ b> A transmits the position information and the situation information at the detected position to the information collection apparatus 100 via the base station 10 </ b> A and the network 1. Then, the information collecting apparatus 100 accumulates the received position information and situation information.

  Here, the general information collection device 100 stores information unilaterally transmitted from the communication device 200. Therefore, it is difficult for the information collection device 100 to additionally collect information that the communication device 200 that has detected the dangerous state did not acquire. On the other hand, it is conceivable to supplement information that has not been acquired by constantly transmitting information related to detection of a dangerous state to all the communication devices 200, for example, situation information. There is a possibility of increasing the amount of communication and causing frequent congestion. Therefore, in the information collection system according to the embodiment of the present invention, the first communication device 200 that has detected the dangerous state of the transport device has the first information at the dangerous state detection position (hereinafter also referred to as a dangerous point). Is transmitted to the information collecting apparatus 100. Next, the second communication device 200 receives an information transmission request transmitted from a device outside the transport equipment in which the first communication device 200 is installed. Next, the second communication device 200 that receives the information transmission request transmits the second information at the detection position of the dangerous state to the information collection device 100. Then, the information collecting apparatus 100 stores the second information in association with the detection position of the dangerous state.

  For example, the communication device 200A illustrated in FIG. 1 detects a dangerous state of the vehicle 20A, and transmits position information, status information, and the like at the detection position to the information collection device 100. Then, the information collecting apparatus 100 accumulates the received position information and situation information, and transmits a transmission request for the surrounding information of the vehicle 20B at the position indicated by the position information to the communication apparatus 200B. When the information transmission request is received, the communication device 200B acquires the peripheral information of the vehicle 20B at the designated position, and transmits the acquired peripheral information to the information collection device 100. Then, the information collection device 100 accumulates the received surrounding information of the vehicle 20B in association with the position information.

  As described above, in the information collection system according to the embodiment of the present invention, the first communication device 200 that has detected the dangerous state of the transport device transmits the first information at the detection position of the dangerous state to the information collection device 100. To do. Next, the second communication device 200 receives an information transmission request transmitted from a device outside the transport equipment in which the first communication device 200 is installed. Next, the second communication device 200 that receives the information transmission request transmits the second information at the detection position of the dangerous state to the information collection device 100. Then, the information collecting apparatus 100 stores the second information in association with the detection position of the dangerous state. For this reason, by collecting only the second information acquired at the detection position of the dangerous state, the information at the position where the dangerous state of the transport device is detected is efficiently collected while suppressing the traffic. It becomes possible to do. For convenience of explanation, the information collecting apparatus 100 and the communication apparatus 200 according to the first to third embodiments are numbered corresponding to the embodiment at the end like the information collecting apparatus 100-1 to the information collecting apparatus 100-3. It distinguishes by attaching.

<2. First embodiment of the present invention>
The outline of the information collection system according to the embodiment of the present invention has been described above.

FIG. 2 is a block diagram showing a schematic functional configuration of the information collection system according to the first embodiment of the present invention.

  As illustrated in FIG. 2, the information collection system according to the present embodiment includes an information collection device 100-1 and a communication device 200-1. The information collection device 100-1 may be a server or the like that is connected to the communication device 200-1 via a network. Communication device 200-1 may be a vehicle-mounted device installed in vehicle 20 or the like as a transport device.

  As illustrated in FIG. 2, the communication device 200-1 includes a control unit 202, a detection unit 204, an information acquisition unit 206, and a communication unit 208.

  The control unit 202 controls the operation of the communication device 200-1. Specifically, the control unit 202 instructs the detection unit 204 to detect a dangerous state. Then, when a dangerous state is detected by the detection unit 204, the control unit 202 is also referred to as the position of the vehicle 20 on which the communication device 200-1 is installed (hereinafter also referred to as the position of the communication device 200-1). ) Is determined to be a dangerous spot. For example, the control unit 202 can instruct the detection unit 204 to detect a dangerous state every predetermined time. Note that the control unit 202 may instruct the detection unit 204 to perform detection when a predetermined operation or action or the like occurs in the vehicle 20. For example, the control unit 202 instructs the detection unit 204 to perform detection when an operation such as sudden braking or sudden steering is performed and information related to the operation is acquired by the information acquisition unit 206. When the detection unit 204 detects a dangerous state, the control unit 202 determines that the position indicated by the position information acquired by the information acquisition unit 206 together with the information related to the operation is a dangerous part.

  In addition, the control unit 202 instructs the information acquisition unit 206 to acquire information. For example, when the information transmission request is received from the information collection device 100-1, the control unit 202, when the vehicle 20 in which the communication device 200-1 is installed reaches the vicinity of the position specified from the information transmission request. Then, the information acquisition unit 206 is instructed to acquire the surrounding information of the vehicle 20. The position information of the vehicle 20 is acquired by the information acquisition unit 206 every elapse of a predetermined time. Further, the periphery of the position specified from the information transmission request can be within a predetermined distance from the specified position.

  The control unit 202 controls communication of the communication unit 208. For example, when the dangerous part is determined, the control unit 202 informs the communication unit 208 as the first information information indicating the situation in the vehicle 20 when the dangerous part is detected (hereinafter also referred to as vehicle situation information). .) Is transmitted to the information collecting apparatus 100-1 together with the position information acquired by the information acquiring unit 206. In addition, the control unit 202 causes the communication unit 208 to transmit information that is acquired by the information acquisition unit 206 to the information collection device 100-1 as the second information when an information transmission request is received. The vehicle status information may be either or both of vehicle information and driver information, or may be information used for detection of a dangerous state by the detection unit 204 of the vehicle information and the driver information. Good. Further, the vehicle status information and the surrounding information may be transmitted after a predetermined time has elapsed since the acquisition by the information acquisition unit 206 or after the communication device 200-1 arrives at a predetermined position. When a request from is received, it may be sent as a response to the request.

  The detection unit 204 detects a dangerous state based on an instruction from the control unit 202 as a part of the control unit. Specifically, when the detection unit 204 receives a detection instruction from the control unit 202, the detection unit 204 instructs the information acquisition unit 206 to acquire position information and vehicle situation information, and the danger in the vehicle 20 based on the acquired vehicle situation information. Try to detect the condition. Then, the detection unit 204 notifies the control unit 202 of the detection result.

  For example, when the detection unit 204 receives a detection instruction from the control unit 202, the detection unit 204 instructs the information acquisition unit 206 to acquire position information and vehicle status information, and based on the driver information in the acquired vehicle status information, Detection of whether the driver's eyes of the vehicle 20 are closed (hereinafter also referred to as eye closing detection) is performed. For the closing of the eyes, a technique using an image analysis technique as disclosed in JP2013-109401A or other general techniques for detecting the closing of the eyes can be used. Note that closing the eyes can include narrowing the eyes. When it is detected that the driver has closed his eyes for a predetermined time or longer, the detection unit 204 notifies the control unit 202 that it has detected a dangerous state in the vehicle 20. Further, the detection unit 204 can detect a dangerous state even when there is no instruction from the control unit 202. For example, the detection unit 204 may detect the dangerous state every time a predetermined time elapses, or may detect the dangerous state when the vehicle state information is acquired by the information acquisition unit 206.

  As described above, the vehicle state information includes driver information regarding the state of the driver of the vehicle 20, and the detection unit 204 detects the dangerous state of the vehicle 20 based on the driver information. For this reason, it is possible to determine a dangerous state that is difficult to detect from the operation or operation of the vehicle, thereby increasing the dangerous state to be collected information and contributing to improving traffic safety by eliminating the dangerous state. It becomes possible. Note that the detection unit 204 may detect the dangerous state of the vehicle 20 based on the vehicle information acquired by the information acquisition unit 206.

  The information acquisition unit 206 acquires information related to the vehicle 20 in which the communication device 200-1 is installed. Specifically, the information acquisition unit 206 acquires the surrounding information of the vehicle 20 based on an instruction from the control unit 202, and the position information, vehicle information, and driver of the vehicle 20 based on the instruction from the detection unit 204.

  The position information acquisition unit 210 acquires information related to the position of the vehicle 20 where the communication device 200-1 is installed. For example, the position information acquisition unit 210 may be a GPS sensor that acquires GPS (Global Positioning System) information. Note that the position information acquisition unit 210 may acquire position information from a device such as a beacon or an ITS spot installed on the roadside via the communication unit 208.

  The vehicle information acquisition unit 212 acquires information related to the operation or operation of the vehicle 20. For example, the vehicle information acquisition unit 212 acquires travel information such as a brake or accelerator opening, a steering angle, a vehicle speed, or an engine speed. The vehicle information acquisition unit 212 can acquire travel information detected by a sensor provided in the vehicle 20 via an in-vehicle network using a communication protocol such as CAN (Controller Area Network). Further, the vehicle information acquisition unit 212 may acquire the temperature, humidity, illuminance, voice, fuel remaining amount, or the like in the vehicle.

  The driver information acquisition unit 214 acquires information related to the state or movement of the person driving the vehicle 20. For example, the driver information acquisition unit 214 acquires information indicating a state such as a driver's side view, closed eyes or doze, or movement such as an operation such as yawning, opening a window or car navigation. Note that the driver's state or movement information can be generated by analyzing an image obtained by imaging by an imaging device provided in the vehicle 20. The driver information may be a driver's heart rate or psychological state.

  The peripheral information acquisition unit 216 acquires external information of the vehicle 20. For example, the surrounding information acquisition unit 216 acquires information related to the weather around the vehicle 20, other vehicles, people, or structures. The external information of the vehicle 20 can be generated by analyzing an image obtained by an imaging device provided in the vehicle 20 capturing an image of the periphery of the vehicle 20. Further, the weather information may be acquired from an external device via the communication unit 208.

  The communication unit 208 communicates with the information collection device 100-1. Specifically, the communication unit 208 transmits position information and vehicle status information as the first communication device 200-1, and the peripheral information acquired by the information acquisition unit 206 as the second communication device 200-1. Is transmitted to the information collecting apparatus 100-1. In addition, the communication unit 208 receives an information transmission request from the information collection device 100-1. For example, the communication unit 208 can perform communication using mobile phone communication such as 3G or LTE (Long Term Evolution), medium / long range wireless communication such as WiMAX (registered trademark), satellite communication, or the like. When transmitting information as a response to the information transmission request, the communication unit 208 can transmit information to which information indicating that it is a response to the information transmission request is added.

  Further, as illustrated in FIG. 2, the information collection device 100-1 includes a communication unit 102, a control unit 104, a storage unit 106, and a cause analysis unit 108.

  The communication unit 102 communicates with the communication device 200-1. Specifically, the communication unit 102 receives position information and vehicle situation information from the communication device 200-1 as the first communication device, and receives information from the communication device 200-1 as the second communication device. Receive information obtained by. In addition, the communication unit 102 transmits an information transmission request to the communication device 200-1 as the second communication device.

  The control unit 104 controls the operation of the information collection device 100-1. Specifically, the control unit 104 causes the communication unit 102 to transmit an information transmission request to the communication device 200-1. For example, when the position information and the vehicle situation information are received from the communication device 200-1, the control unit 104 causes the storage unit 106 to store the position information and the vehicle situation information. Then, the control unit 104 causes the communication unit 102 to transmit an information transmission request to the communication device 200-1 that can acquire the peripheral information at the position specified from the position information. For example, the information transmission request includes at least a transmission request for peripheral information to the communication device 200-1 and position information indicating a position where the peripheral information should be acquired. Furthermore, with reference to FIG. 3 and FIG. 4, the operation | movement which concerns on the information transmission request of the control part 104 is demonstrated in detail. FIG. 3 is a diagram illustrating an example of communication in the information collection system according to the present embodiment, and FIG. 4 is a diagram illustrating an example of communication performed after the communication in FIG.

  First, the communication unit 102 receives position information and vehicle status information from the communication device 200-1. For example, when a dangerous point is detected in the communication device 200-1A installed in the vehicle 20A shown in FIG. 3, the position information and the vehicle status in the dangerous point are sent from the communication device 200-1A to the information collecting device 100-1. Information is sent. And the communication part 102 receives the said positional information and vehicle status information.

  Next, the control unit 104 selects a communication device 200-1 capable of acquiring peripheral information at a position specified from the received position information, and the communication device 200-1 from which an information transmission request is selected by the communication unit 102. To send to. For example, each of the communication devices 200-1 periodically transmits position information to the information collection device 100-1, and the control unit 104 manages the position information for each communication device 200-1. Therefore, the control part 104 can estimate the moving direction of each communication apparatus 200-1 based on position information. Therefore, the control unit 104 detects the position information received together with the vehicle status information, that is, the communication device 200-1 whose moving direction is the direction approaching the dangerous place, for example, the communication device installed in the succeeding vehicle 20B shown in FIG. Select 200-1B. Then, the control unit 104 causes the communication unit 102 to transmit an information transmission request to the selected communication device 200-1B. Note that when the position information is received, the control unit 104 may select a communication device 200-1 located within a predetermined distance from the position indicated by the position information.

  And the communication part 102 receives the surrounding information of the vehicle 20 from the communication apparatus 200-1 of the transmission destination of an information transmission request. For example, when the communication device 200-1B that has received the information transmission request reaches the vicinity of the position where the communication device 200-1A has detected the dangerous state, as illustrated in FIG. And the acquired peripheral information is transmitted to the information collecting apparatus 100-1. Then, the communication unit 102 receives the peripheral information, and the control unit 104 causes the storage unit 106 to store the received peripheral information.

  In addition, the control unit 104 instructs the cause analysis unit 108 to analyze the cause of the dangerous state of the vehicle 20. For example, the control unit 104 stores the peripheral information from the communication device 200-1 in the storage unit 106, and then instructs the cause analysis unit 108 to analyze the cause of the dangerous state. The control unit 104 may instruct the cause analysis unit 108 to analyze the cause when a predetermined number of pieces of surrounding information are stored for one vehicle status information. Cause analysis may be directed.

  The storage unit 106 stores information received from the communication device 200-1. Specifically, the storage unit 106 stores position information, vehicle status information, surrounding information, and the like. For example, the storage unit 106 stores the vehicle situation information and the surrounding information in association with the position information. For this reason, vehicle status information and surrounding information are matched via position information. Further, the storage unit 106 stores the analysis result obtained by the cause analysis unit 108.

  The cause analysis unit 108 analyzes the cause of the dangerous state based on an instruction from the control unit 104. Specifically, the cause analysis unit 108 analyzes the cause of the dangerous state at the position indicated by the position information, using the vehicle status information and the peripheral information stored in the storage unit 106. For example, the cause analysis unit 108 performs a plurality of determination processes based on each of the vehicle situation information and the surrounding information, for example, the driver's eye closing determination based on the driver information, or the weather determination based on the surrounding information, etc. The cause of the dangerous state is identified based on the determination result.

When the detection unit 204 detects a dangerous state, the control unit 202 determines the detection position of the dangerous state as a dangerous part. Details will be described later with reference to FIG.

  When the dangerous part is determined, communication device 200-1A transmits position information and vehicle status information (step S304). Specifically, when the dangerous part is determined, the control unit 202 sends the position information of the vehicle 20 acquired by the information acquisition unit 206 and vehicle status information such as driver information to the communication unit 208 as an information collection device. 100-1 is transmitted.

  When the position information and the vehicle situation information are received, the information collection device 100-1 stores the position information and the vehicle situation information (step S306).

The vehicle status information is associated with the position information.

  Next, the information collection device 100-1 transmits an information transmission request to the communication device 200-1B (step S308). Specifically, the control unit 104 selects a communication device 200-1 that can acquire information at a position specified from the received position information. Then, the control unit 104 causes the communication unit 102 to transmit an information transmission request to the selected communication device 200-1.

  When the information transmission request is received, the communication device 200-1B determines whether the communication device 200-1B is located around the dangerous part (step S310). Specifically, every time the position information is periodically acquired by the information acquisition unit 206, the control unit 202 determines that the position indicated by the position information is a predetermined distance from the position indicated by the position information included in the information transmission request. It is determined whether it is within the range.

  If it is determined that the communication device 200-1B is located in the vicinity of the dangerous place, the communication device 200-1B acquires the peripheral information (step S312). Specifically, when it is determined that the position indicated by the position information acquired by the information acquisition unit 206 is within a predetermined distance from the position indicated by the position information included in the information transmission request, the control unit 202 Instructs the information acquisition unit 206 to acquire peripheral information.

  Next, the communication device 200-1B transmits peripheral information to the information collection device 100-1 (step S314). Specifically, when the peripheral information is acquired by the information acquisition unit 206, the control unit 202 causes the communication unit 208 to transmit the peripheral information to the information collection device 100-1.

  When the peripheral information is received, the information collection device 100-1 stores the peripheral information associated with the position information (step S316). Specifically, when the peripheral information is received as a response to the transmitted information transmission request, the control unit 104 associates the peripheral information with the position information included in the information transmission request, and stores the peripheral information in the storage unit 106.

  Then, the information collection device 100-1 analyzes the cause of the dangerous state based on the vehicle status information and the surrounding information (step S318). Specifically, the control unit 104 stores the peripheral information in the storage unit 106 and then issues an analysis instruction to the cause analysis unit 108. When the cause analysis unit 108 receives the analysis instruction, the cause analysis unit 108 performs cause analysis of the dangerous state based on the vehicle state information and the surrounding information. Note that the timing of the analysis instruction by the control unit 104 is arbitrary and is not particularly limited. Details will be described later with reference to FIG.

  Next, details of the process of step S302 in the communication apparatus 200-1 will be described with reference to FIG.

  First, the communication device 200-1 determines whether a predetermined time has elapsed since the previous detection process (step S402). Specifically, the control unit 202 stores the time when the dangerous state detection process is performed, and determines whether a predetermined time has elapsed from the stored time.

  When it is determined that a predetermined time has elapsed since the previous detection process, the communication device 200-1 acquires various types of information (step S404). Specifically, the control unit 202 instructs the detection unit 204 to detect a dangerous state when it is determined that a predetermined time has elapsed since the time when the dangerous point determination process was performed. When the detection unit 204 receives an instruction to detect a dangerous state, the detection unit 204 instructs the information acquisition unit 206 to acquire position information and vehicle status information. When information acquisition is instructed, the information acquisition unit 206 acquires position information of the vehicle 20 and vehicle information and driver information as vehicle status information.

  Next, the communication apparatus 200-1 determines whether the closing of the eyes has occurred for a predetermined time or more (step S406). Specifically, the detection unit 204 causes the information acquisition unit 206 to acquire driver information, for example, a front image of the driver, and the driver information is acquired based on the driver information each time the driver information is acquired. Repeat the closing detection. Then, when the closing of the eyes is detected, the detecting unit 204 determines whether or not the closed state is continued for a predetermined time from the detection of the closing of the eyes.

  When it is determined that the closing of the eyes has occurred for a predetermined time or longer, the communication device 200-1 detects a dangerous state (step S408). Specifically, the detection unit 204 notifies the control unit 202 that a dangerous state has been detected when the closed state is continued for a predetermined time from the detection of the closed eye.

  Next, the details of the process of step S318 will be described with reference to FIG.

  First, the information collection device 100-1 selects vehicle status information and surrounding information (step S502). Specifically, the cause analysis unit 108 selects one vehicle status information from the storage unit 106. Then, the cause analysis unit 108 acquires peripheral information associated with position information indicating a position within a predetermined distance from a position indicated by the position information associated with the vehicle status information. Further, the cause analysis unit 108 selects peripheral information received within a predetermined time range from the reception time of the selected vehicle status information from the acquired peripheral information. The cause analysis unit 108 may use information generation time or the like instead of the reception time.

  Next, the information collecting apparatus 100-1 determines whether the closing of the eyes has occurred for a predetermined time or more (step S504). Specifically, the cause analysis unit 108 determines whether closed eyes over a predetermined time have been detected for the selected vehicle status information. The process for detecting the closing of the eyes is substantially the same as that in step S406 in FIG.

  When it is determined that the closing of the eyes has occurred for a predetermined time or longer, the information collection device 100-1 determines whether the weather is fine (step S506). Specifically, the cause analysis unit 108 determines whether the weather estimated from the surrounding information is clear for each piece of selected surrounding information.

  When it is determined that the weather is fine, the information collecting apparatus 100-1 determines that the cause of the dangerous state is light that is inserted into the vehicle (step S508). Specifically, the cause analysis unit 108 determines that the cause of the dangerous state is sunlight inserted into the driver's seat of the vehicle 20 when the weather information estimated from the surrounding information is determined to be fine weather or more. The reflected light or the like is determined. Or the surrounding information determined that the weather is fine may be one.

  If it is determined in step S508 that the weather is not clear, the information collecting apparatus 100-1 determines that the cause of the dangerous state is another event (step S510). In addition, when it is determined in step S504 that no closing has occurred for a predetermined time or longer, the information collection device 100-1 determines that the cause of the dangerous state is carelessness of the driver (step S512). ).

  As described above, according to the first embodiment of the present invention, the information collection system obtains the first information at the detection position of the dangerous state of the vehicle 20 from the first communication device 200-1 installed in the vehicle 20. An information collecting apparatus 100-1 for receiving is provided. In addition, the information collection device 100-1 is the information related to the first information from the second communication device 200-1 installed in a device outside the vehicle 20, and the second communication device 200-1 from another device. The second information at the detection position, which is transmitted when a transmission request is received, is received. Furthermore, the information collection device 100-1 stores the second information in association with the detection position. For this reason, only the second information at the detection position of the first information is additionally collected from the communication device 200-1, so that the traffic volume is suppressed and the position at which the dangerous state of the vehicle 20 is detected. Information can be collected efficiently.

  The second communication device 200-1 is installed in another vehicle 20 different from the vehicle 20 described above, and the information transmission request is received from a device outside the other vehicle 20. For this reason, the 2nd communication apparatus 200-1 is installed in the vehicle 20 similarly to the 1st communication apparatus 200-1, and it is in the situation similar to the time of the dangerous state detection of the 1st communication apparatus 200-1. The second information is acquired, and the effectiveness of the second information in the cause analysis of the dangerous state can be improved.

  In addition, the device outside the other transport device includes an information collecting device 100-1, and when the information collecting device 100-1 receives the first information, it sends an information transmission request in the above dangerous state. It transmits to the 2nd communication apparatus 200-1 which can acquire said 2nd information in a detection position. For this reason, by transmitting an information transmission request from the information collection device 100-1 that collects information from the communication device 200-1, it becomes easy to specify the communication device 200-1 as the transmission destination, and the second information is efficiently obtained. Can be collected.

  Further, the information collection device 100-1 analyzes the cause of the dangerous state using the first information and the second information associated with the detection position related to the first information. For this reason, it is possible not only to collect information relating to the dangerous state but also to automatically analyze the cause of the dangerous state, thereby shortening the time required for investigating the cause of the dangerous state.

  The second information includes information of a different type from the first information, and the cause analysis unit 108 analyzes the cause of the dangerous state using the information of the different type. For this reason, the information which is not acquired by the first communication device 200-1 or failed to be acquired is acquired by the second communication device 200-1, thereby increasing the amount of information used for the cause analysis of the dangerous state, It is possible to improve the accuracy of the cause analysis.

  Moreover, said 1st information contains the driver information about the driver | operator's state of the vehicle 20, and said 2nd information is said 1st communication apparatus 200-1 in the detection position of a dangerous state. The surrounding information of the vehicle 20 in which is installed. For this reason, since the information used for the cause analysis has a complementary relationship such as the environment inside and outside the vehicle 20, it is possible to expand the range in which the cause can be specified.

(2-3. Modifications)
The first embodiment of the present invention has been described above. In addition, this embodiment is not limited to the above-mentioned example. Below, the modification of this embodiment is demonstrated.

  As a modification of the present embodiment, the information received from the second communication device 200-1 as a response to the information transmission request is the same type as the information received from the first communication device 200-1. May be included. Specifically, information received from the first and second communication devices 200-1 (hereinafter also referred to as analysis information) includes vehicle status information and surrounding information. The analysis information is stored in the storage unit 106 in association with the position information and the time information. Then, the cause analysis unit 108 selects the analysis information stored in the storage unit 106 and compares the selected analysis information to analyze the cause of the dangerous state. The process of cause analysis of the dangerous state in this modification will be described in detail with reference to FIG. FIG. 8 is a flowchart showing the cause analysis process (the process of step S318 in FIG. 5) according to a modification of the present embodiment. Note that description of processing that is substantially the same as the processing in FIG. 7 is omitted.

  First, the information collecting apparatus 100-1 selects information for analysis (step S602). Specifically, the cause analysis unit 108 selects one piece of analysis information from the storage unit 106. Then, the cause analysis unit 108 acquires analysis information associated with position information indicating a position within a predetermined distance from a position indicated by the position information associated with the analysis information.

  Next, the information collecting apparatus 100-1 determines whether or not the closing of a predetermined time or more has occurred in the plurality of communication apparatuses 200-1 (step S604). Specifically, the cause analysis unit 108 determines whether or not a closing time over a predetermined time is detected for each piece of analysis information to be selected. The process for detecting the closing of the eyes is substantially the same as that in step S406 in FIG.

  When it is determined that the closing of a predetermined time or more has occurred in the plurality of communication devices 200-1, the information collection device 100-1 determines whether the time difference related to the analysis information is within a predetermined time range. (Step S606). Specifically, when there is a predetermined number of pieces of analysis information for which it is determined that the closing of the eyes for a predetermined time or more has been detected, the cause analysis unit 108 associates each piece of analysis information with the analysis information. It is determined whether the time indicated by the information is within a predetermined time range. For example, the time information associated with the analysis information can be the generation time or the reception time of the analysis information.

  When it is determined that the difference between the occurrence times of the closed eyes is within a predetermined time range, the information collection device 100-1 determines whether the weather related to the plurality of communication devices 200-1 is clear (step). S608). Specifically, when there is a predetermined number of pieces of analysis information for which it is determined that the closing occurrence time is within a predetermined time range, the cause analysis unit 108 performs analysis information for each piece of the analysis information. It is determined whether the weather estimated from the surrounding information included in is clear weather.

  When it is determined that the weather related to the plurality of communication devices 200-1 is sunny, the information collection device 100-1 determines that the cause of the dangerous state is light that is inserted into the vehicle (step S610). Specifically, the cause analysis unit 108 determines that the cause of the dangerous state is sunlight that is inserted into the driver's seat of the vehicle 20 when there is a predetermined number or more of analysis information determined that the weather estimated from the surrounding information is clear weather. Or it determines with it being the reflected light.

  Note that if it is determined in step S608 that the weather related to the plurality of communication devices 200-1 is not clear, the information collection device 100-1 determines that the cause of the dangerous state is another event (step S612). . If the information collecting apparatus 100-1 determines in step S504 that the plurality of communication apparatuses 200-1 have not closed the eyes for a predetermined time or more, the cause of the dangerous state is carelessness of the driver. It is determined that

  Thus, according to the modification of the present embodiment, the first and second information received from the first and second communication devices 200-1 include information of the same type, and the cause analysis unit 108 analyzes the cause of the dangerous state by comparing information of the same type. For this reason, it is possible to improve the accuracy of the cause analysis using the type of information as compared with the case where the cause analysis of the dangerous state is performed using only a single piece of information.

  In addition, the second information is stored in association with time information, and the cause analysis unit 108 includes the first information and the second information in a range in which the time indicated by the time information is determined in advance. Analyze using information. For this reason, it is possible to further improve the accuracy of the cause analysis by using the first information and the second information having a relatively high temporal relevance for the cause analysis of the dangerous state.

<3. Second embodiment of the present invention>
The information collection system according to the first embodiment of the present invention has been described above. Next, an information collection system according to the second embodiment of the present invention will be described. In the present embodiment, when detecting a dangerous state, the communication device 200-2 transmits the first information to the information collecting device 100-2, and sends the second information at the detection position of the dangerous state to the other communication device 200-2. Send a request to send information.

(3-1. Configuration of information collection system)
First, the functional configuration of the information collection system according to the second embodiment of the present invention will be described with reference to FIG. FIG. 9 is a block diagram showing a schematic functional configuration of an information collection system according to the second embodiment of the present invention. Note that a description of a configuration that is substantially the same as that of the first embodiment will be omitted.

  In this embodiment, the functional configuration of the information collection system is substantially the same as that of the first embodiment, but the operations of the control unit 202 and the communication unit 208 of the communication device 200-2 are partially different.

  The control unit 202 causes the communication unit 208 to transmit an information transmission request to the other communication device 200-2B. Specifically, when the dangerous part is determined, the control unit 202 causes the communication unit 208 to transmit the vehicle status information to the information collection device 100-2 together with the position information acquired by the information acquisition unit 206. . Note that the information transmission request includes position information indicating the dangerous location as the position where the peripheral information as the second information is to be acquired.

  The communication unit 208 communicates with another communication device 200-2B. Specifically, the communication unit 208 specifies the other communication device 200-2B as the transmission destination of the information transmission request, and transmits the information transmission request to the specified other communication device 200-2B. The processing of the communication unit 208 will be described in detail with reference to FIG. FIG. 10 is a diagram illustrating an example of communication in the information collection system according to the present embodiment.

For example, when the control unit 202 instructs the communication unit 208 to transmit an information transmission request, as illustrated in FIG. 10, as illustrated in FIG. -2. As described above, since the information collection device 100-2 can estimate the moving direction of the communication device 200-2, the communication device 200-2B corresponding to the inquiry content from the communication device 200-2A is selected and selected. The communication device 200-2A responds with information identifying the communication device 200-2B.

  Then, the communication unit 208 transmits an information transmission request to the other specified communication device 200-2. For example, the communication unit 208 transmits an information transmission request to the communication device 200-2B based on the information specifying the communication device 200-2B received from the information collection device 100-2, as illustrated in FIG. To do.

  In the above description, the communication unit 208 communicates with another communication device 200-2B using a network such as mobile phone communication. However, the communication unit 208 uses the ad hoc communication to communicate with another communication device 200-2B. You may communicate with. For example, the communication unit 208 transmits an information transmission request so that information is propagated toward the communication device 200-2 located within a predetermined distance from the dangerous part. The other communication device 200-2 that has received the information transmission request further transmits the information transmission request when the communication device 200-2 is located within a predetermined distance from the dangerous point or closer to the dangerous point than the transmission source. To do. In this case, by communicating with another communication device 200-2 without using a network such as mobile phone communication, an information transmission request is transmitted to the communication device while preventing an increase in the amount of communication in the network such as mobile phone communication. 200-2 can be transmitted. Note that the communication is not limited to multi-hop communication, and may be completed in one hop.

(3-2. Information collection system processing)
Next, the process of the information collection system in this embodiment is demonstrated with reference to FIG. FIG. 11 is a sequence diagram conceptually showing processing of the information collection system in this embodiment. Note that description of processing that is substantially the same as processing in the first embodiment is omitted.

  First, the communication device 200-2A determines a dangerous place (step S702).

  When the dangerous part is determined, the communication device 200-2A transmits an information transmission request to the other communication device 200-2B (step S704). Specifically, when the dangerous part is determined, the control unit 202 generates an information transmission request and instructs the communication unit 208 to transmit the information transmission request. Upon receiving the transmission instruction, the communication unit 208 specifies the transmission destination of the information transmission request by an inquiry to the information collection device 100-2, and transmits the information transmission request toward the specified communication device 200-2B.

  Further, the communication device 200-2A transmits the position information and the vehicle situation information (step S706), and when the position information and the vehicle situation information are received, the information collection device 100-2 receives the position information and the vehicle situation information. Is stored (step S708).

  When the information transmission request is received, the communication device 200-2B determines whether or not the communication device 200-2B is located around the dangerous location (step S710). The peripheral information is acquired (step S712).

  Next, the communication device 200-2B transmits the peripheral information to the information collecting device 100-2 (step S714). When the peripheral information is received, the information collecting device 100-2 is associated with the position information. The peripheral information is stored (step S716).

  Then, the information collection device 100-2 analyzes the cause of the dangerous state based on the vehicle status information and the surrounding information (step S718).

As described above, according to the second embodiment of the present invention, the information collection system uses the first information at the detection position of the dangerous state of the vehicle 20 from the other communication device 200-2 installed in the vehicle 20. When the information transmission request is received, the communication apparatus 200-2 is provided that acquires the second information at the detection position. Then, when the second information is acquired, the communication device 200-2 transmits the acquired second information toward the information collection device 100-2. For this reason,
Compared to the case where the information collection device 100-2 transmits an information transmission request, the processing load on the information collection device 100-2 is reduced, and it becomes possible to prevent the exhaustion of computing resources and the decrease in processing speed.

<4. Third Embodiment of the Invention>
The information collection system according to the second embodiment of the present invention has been described above. Next, an information collection system according to the third embodiment of the present invention will be described. In the present embodiment, the information collection device 100-3 transmits an information transmission request to another communication device 200-3 when a dangerous state is detected based on the first information received from the communication device 200-3. To do.

(4-1. Configuration of information collection system)
First, a functional configuration of an information collection system according to the third embodiment of the present invention will be described with reference to FIG. FIG. 12 is a block diagram showing a schematic functional configuration of an information collection system according to the third embodiment of the present invention. Note that a description of a configuration substantially the same as that of the first and second embodiments is omitted.

  In this embodiment, the functional configuration of the communication device 200-3 is substantially the same as that of the first embodiment, but the functional configuration of the information collection device 100-3 is different from those of the first and second embodiments.

  As illustrated in FIG. 12, the information collection device 100-3 includes a detection unit 110 in addition to the communication unit 102, the control unit 104, the storage unit 106, and the cause analysis unit 108.

  When the vehicle status information is received, the control unit 104 determines whether or not to transmit an information transmission request based on the vehicle status information. Specifically, when vehicle status information is received from communication device 200-3, control unit 104 instructs detection unit 110 to detect a dangerous state based on the vehicle status information. For example, when the vehicle status information is received from the communication device 200-3, the control unit 104 instructs the detection unit 110 to detect a dangerous state along with the vehicle status information. Then, upon receiving notification that the dangerous state has been detected by the detection unit 110, the control unit 104 determines to transmit an information transmission request.

  Further, the control unit 104 controls the transmission of the information transmission request based on the determination result of whether or not the information transmission request is transmitted. Specifically, when it is determined that the information transmission request is to be transmitted, the control unit 104 generates an information transmission request and causes the communication unit 102 to transmit the information transmission request to the communication device 200-3.

  The detection unit 110 detects a dangerous state based on a detection instruction from the control unit 104 as a part of the control unit. Specifically, upon receiving a detection instruction from the control unit 104, the detection unit 110 detects a dangerous state based on vehicle status information received from the control unit 104. And the detection part 110 notifies that to the control part 104, when a dangerous state is detected. The dangerous state detection process is substantially the same as the process of the detection unit 204 of the first embodiment, and thus description thereof is omitted.

(4-2. Processing of information collection system)
Next, the process of the information collection system in this embodiment is demonstrated with reference to FIG. FIG. 13 is a sequence diagram conceptually showing processing of the information collection system in the present embodiment. Note that description of processing that is substantially the same as processing in the first embodiment is omitted.

  First, the communication device 200-3A determines a dangerous place (step S802).

  When the dangerous part is determined, the communication device 200-3A transmits the position information and the vehicle situation information (step S804). When the position information and the vehicle situation information are received, the information collection device 100-3 The position information and the vehicle status information are stored (step S806).

  Further, the information collection device 100-3 determines a dangerous place (step S808). Specifically, when the vehicle status information is received, the control unit 104 instructs the detection unit 110 to detect a dangerous state based on the vehicle status information, for example, driver information. And if the detection part 110 receives the said detection instruction | indication, it will detect the dangerous state of the vehicle 20 using vehicle status information. Then, the detection unit 110 notifies the control unit 104 that a dangerous state has been detected.

  When the dangerous part is determined, the information collection device 100-3 transmits an information transmission request to the communication device 200-3B (step S810). Specifically, when the detection unit 110 notifies that the dangerous state has been detected, the control unit 104 causes the communication unit 102 to transmit an information transmission request to the communication device 200-3B.

  When the information transmission request is received, the communication device 200-3B determines whether or not the communication device 200-3B is located around the danger detection position (step S812). -3B acquires peripheral information (step S814).

  Next, the communication device 200-3B transmits the peripheral information to the information collection device 100-3 (step S816). When the peripheral information is received, the information collection device 100-3 is associated with the position information. The peripheral information is stored (step S818).

  Then, the information collection device 100-3 analyzes the cause of the dangerous state based on the vehicle status information and the surrounding information (step S820).

  As described above, according to the third embodiment of the present invention, when the first information is received, the control unit 104 determines whether or not to transmit an information transmission request based on the first information. For this reason, it is possible to reduce the amount of communication by suppressing the transmission of the information transmission request.

  Moreover, the detection part 110 detects the dangerous state of the vehicle 20 based on said 1st information, and when the dangerous state of the vehicle 20 is detected, it determines with the control part 104 transmitting an information transmission request. . For this reason, it is possible to prevent erroneous transmission of an information transmission request due to erroneous detection of a dangerous part in the communication apparatus 200-3 by determining the dangerous part also in the information collecting apparatus 100-3.

  In the above description, an example in which the detection processing of the detection unit 110 and the detection unit 204 is substantially the same has been described, but both detection processing may be different. Specifically, the detection process of the dangerous place by the detection unit 110 can be performed with higher accuracy than the detection process by the detection unit 204 in the first embodiment. For example, the resolution or the like of the image analysis process used in the eye closing determination based on the driver information may be set higher than the process of the detection unit 204, or the image compression rate may be reduced. In this case, it is possible to further improve the efficiency of communication related to the information transmission request by improving the accuracy of the determination on whether or not the information transmission request is transmitted.

(4-3. Modifications)
Heretofore, the third embodiment of the present invention has been described. In addition, this embodiment is not limited to the above-mentioned example. Below, the modification of this embodiment is demonstrated.

  As a modification of the present embodiment, the information collection device 100-3 may detect a dangerous state using each of the vehicle situation information received from the plurality of vehicles 20. Specifically, the detection unit 110 detects the dangerous state of the vehicle 20 based on each of the vehicle situation information received from the plurality of communication devices 200-3 and associated with the position information. When the dangerous state of the vehicle 20 is detected for at least two or more vehicle status information, the detection unit 110 notifies the control unit 104 that the dangerous state has been detected. And the control part 104 will determine with transmitting an information transmission request, if the said notification is received. The processing of this modification will be described in detail with reference to FIG. FIG. 14 is a sequence diagram conceptually showing the processing of the information collection system in the modification of the present embodiment.

  First, the communication devices 200-3A and 200-3B determine a dangerous place (steps S902 and S904).

  When the dangerous part is determined, the communication devices 200-3A and 200-3B transmit the position information and the vehicle situation information (steps S906 and S910), and when the position information and the vehicle situation information are received, the information collection device 100-3 memorize | stores the said positional information and vehicle status information (step S908, S912).

  Next, the information collecting apparatus 100-3 determines a dangerous place (step S914). Specifically, when a plurality of, for example, two or more pieces of vehicle situation information are received within a predetermined time, the control unit 104 determines whether the position indicated by the position information associated with the vehicle situation information is within a predetermined geographical range. judge. When the position indicated by the position information is within a predetermined geographical range, the control unit 104 instructs the detection unit 110 to detect a dangerous state based on each of the vehicle status information. Upon receiving the detection instruction, the detection unit 110 detects the dangerous state of the vehicle 20 using each of the vehicle status information. When there are a plurality of vehicle status information for detecting the dangerous state of the vehicle 20, for example, two or more, the detection unit 110 notifies the control unit 104 that the dangerous state has been detected.

  When the dangerous part is determined, the information collection device 100-3 transmits an information transmission request to the communication device 200-3B (step S916).

  When the information transmission request is received, the communication device 200-3B determines whether or not the communication device 200-3B is located around the danger occurrence detection position (step S918). -3B acquires peripheral information (step S920).

  Next, the communication device 200-3B transmits the peripheral information to the information collection device 100-3 (step S922).

<6. Conclusion>
As described above, according to the first embodiment of the present invention, only the second information at the detection position of the first information is additionally collected from the communication device 200-1, thereby suppressing the communication amount. It is possible to efficiently collect information at a position where the dangerous state of the vehicle 20 is detected.
In addition, according to the second embodiment of the present invention, the processing load on the information collection device 100-2 is reduced compared to the case where the information collection device 100-2 transmits an information transmission request, and the depletion of computing resources and It is possible to prevent a decrease in processing speed. Further, according to the third embodiment of the present invention, the transmission of information transmission requests can be suppressed, so that the amount of communication can be reduced.

  The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious that a person having ordinary knowledge in the technical field to which the present invention pertains can come up with various changes or modifications within the scope of the technical idea described in the claims. Of course, it is understood that these also belong to the technical scope of the present invention.

  For example, in the above-described embodiment, the communication apparatus 200 transmits the vehicle status information to the information collection apparatus 100 when determining the dangerous place, but the present invention is not limited to such an example. For example, the communication device 200 may store vehicle status information acquired when a dangerous place is determined, and transmit the vehicle status information to the information collection device 100 after a predetermined event occurs. For example, the predetermined event may be a transmission standby time-out event for the vehicle status information, or may be a reception of a vehicle status information transmission request from the information collection device 100. In this case, it is possible to reduce the amount of communication and the processing load related to communication compared to the case where vehicle status information or the like is transmitted each time a dangerous place is determined.

  Further, in the above-described embodiment, an example in which the information transmission request includes information indicating a position where the second communication device 200 should acquire the second information, that is, a dangerous location, has been described. When the communication device 200 reaches the dangerous place, the information transmission request may be transmitted. For example, since the information collection device 100 manages the position information of the communication device 200 as described above, the control unit 104 has the communication device 200 within a predetermined distance from the dangerous place at predetermined time intervals. Judge whether to do. Then, the control unit 104 causes the communication unit 102 to transmit an information transmission request toward the communication device 200 where it is determined that the communication device 200 exists within a predetermined distance from the dangerous location. In this case, since it is not necessary to include the position information in the information transmission request, it is possible to reduce the communication amount and to omit the position determination process of the own apparatus in the communication apparatus 200.

  In the above embodiment, the information transmission request is transmitted to the communication device 200 specified as the transmission destination. However, the information transmission request is transmitted to the specified roadside communication device, and It may be transmitted from the roadside communication device to the peripheral communication device 200. For example, the information collecting apparatus 100 holds information related to a position where a roadside communication device such as an ITS spot is installed, for example, in the storage unit 106 or the like. When the vehicle situation information is received, the control unit 104 identifies a roadside communication device within a predetermined distance from the position indicated by the position information accompanying the vehicle situation information, and the identified roadside communication device. For this, the communication unit 102 is caused to transmit an information transmission request. The roadside communication device that receives the information transmission request broadcasts the information transmission request for a predetermined time or a predetermined number of times, and the communication apparatus 200 receives the broadcasted information transmission request. In this case, the location information of the communication device 200 is not constantly transmitted to the information collection device 100, and the amount of communication can be reduced.

  The information transmission request may be provided with an expiration date, and when the expiration date has expired, the communication apparatus 200 does not perform a response process for the information transmission request even when the information transmission request is received. Also good. In this case, it is possible to prevent the response communication to the information transmission request from being performed excessively and suppress the occurrence of communication congestion.

  Further, the transmission destination of the information transmission request may be changed according to the dangerous state. For example, the control unit 104 of the information collection device 100 increases or decreases the number of communication devices 200 that are transmission destinations of information transmission requests according to the risk level of the dangerous state determined from the vehicle status information or the like, Scale the geographic range. In this case, by preferentially collecting information related to a dangerous state having a relatively high risk, it becomes possible to analyze the cause of the dangerous state prior to other dangerous states.

  Moreover, although the said embodiment demonstrated the example in which the 2nd communication apparatus 200 was installed in transport equipment, the 2nd communication apparatus 200 may be arrange | positioned fixedly. In this case, the transmission destination of the information transmission request can be easily specified, the transmission process of the information transmission request can be simplified, and the processing time can be shortened.

  In the above embodiment, the first and second communication devices 200 have the same functional configuration. However, the functional configurations of the first and second communication devices 200 may be different. For example, the second communication device 200 may not include the detection unit 204 and only perform a response process to the information transmission request. In this case, the first communication device 200 is installed in a transportation device owned by a general person, and the second communication device 200 is owned by an information collection system provider, for example, a business operator who conducts a survey of dangerous places. Can be installed in the transport equipment.

  Further, the communication device 200 may transmit different information to the information collection device 100 according to the position where the information transmission request is received. For example, the control unit 202 of the communication device 200 differs depending on the position indicated by the information transmission request from the position indicated by the position information acquired by the information acquisition unit 206 when the information transmission request is received, that is, the distance from the dangerous location. Information may be transmitted to the communication unit 208. In this case, when the information suitable for the cause analysis of the dangerous state is different depending on the position of the communication device 200, only the suitable information is communicated, whereby the communication can be made efficient.

  Further, the information collection device 100 may determine whether or not to transmit an information transmission request based on the reception status of the first information. For example, the control unit 104 of the information collection device 100 does not transmit an information transmission request when a predetermined time has elapsed since the reception of the first information, or when the number of receptions of the first information is equal to or less than a predetermined number. judge. In this case, the transmission of the information transmission request is stopped when there is a possibility that the effectiveness in the cause analysis of the second information received as a response to the information transmission request may be low, thereby suppressing unnecessary communication. Is possible.

  In the above embodiment, an example in which the transportation device in which the communication device 200 is installed is the vehicle 20, but the transportation device may be an aircraft, a ship, or a vehicle operated by another person.
