Summary of the Invention

Problems to be Solved by the Invention

[0004] In addition, on a toll road, the tollgate may be temporarily closed due to equipment failure, weather, disasters, accidents, etc. stopping traffic. At this time, not only nearby vehicles need to be notified, but it is also necessary to transmit to each tollgate on the toll road where and what kind of incident has occurred (hereinafter, also referred to as "incident information"). However, in the conventional toll road system, when a toll collector or the like discovers an incident, a manual operation is performed to transmit the incident information to other tollgates by phone or the like. Such a response places a heavy workload on the toll collector and makes it difficult to promptly transmit the incident information to all tollgates affected by the incident. For this reason, there has been a possibility that the handling of incidents at each tollgate is delayed.

[0005] The present disclosure provides a monitoring device, a tollgate device, a monitoring system, a monitoring method, and a program that can share incident information between tollgates and promptly perform processing corresponding to the incident at each tollgate.

[0007] Also, according to one aspect of the present disclosure, a tollgate device installed at a tollgate includes a recording processing unit that records the incident information distributed from the monitoring device on a recording medium in the own device, and an incident processing unit that performs processing according to the incident information.

[0008] Also, according to one aspect of the present disclosure, a monitoring system includes the above-described monitoring device and the above-described tollgate device.

[0009] Also, according to one aspect of the present disclosure, a monitoring method includes a step of creating incident information including incident type information indicating the type of an incident when the incident is detected, and a step of distributing the incident information to a tollgate device of a tollgate that performs processing corresponding to the incident type information.

[0010] Also, according to one aspect of the present disclosure, a program causes a computer of a monitoring device to execute a step of creating incident information including incident type information indicating the type of an incident when the incident is detected, and a step of distributing the incident information to a tollgate device of a tollgate that performs processing corresponding to the incident type information.

Advantages of the Invention

[0011] According to each of the above aspects, incident information can be shared among toll gates, and processing corresponding to the incident can be promptly performed at each toll gate.

[0013] <First Embodiment> Hereinafter, a monitoring system according to the first embodiment will be described with reference to the drawings.

[0014] (Overall Configuration of Toll Collection System) FIG. 1 is a diagram showing the overall configuration of the monitoring system according to the first embodiment. The monitoring system 9 shown in FIG. 1 is for sharing information regarding an incident that has occurred at a tollgate or the like on a toll road U among tollgates and causing each tollgate to perform processing for the incident.

[0015] An incident is, for example, a failure of various devices installed at a tollgate, or a traffic stop due to weather, an accident, etc., and is an event that requires a response such as closing some or all lanes at the tollgate. Also, an incident may be an event that requires a response such as the apprehension of an illegally passing vehicle (over axle weight, illegal modification, etc.) (reporting, charging an additional toll, etc.).

[0016] The configuration of the toll road U will be described. As shown in FIG. 1, the toll road U has an entrance tollgate G2, an exit tollgate G3, and a main line tollgate G4 on the main line LM. The toll road U according to the present embodiment performs toll collection processing using an Electronic Toll Collection System (ETC (registered trademark)). The Electronic Toll Collection System enables automatic toll collection processing (settlement processing) for vehicles in motion by performing wireless communication between a wireless communication device installed in each lane of the tollgate and an in-vehicle unit mounted on the vehicle. Note that in other embodiments, a toll collector may be stationed at each tollgate of the toll road U, and the toll collector may receive the toll from the passengers (users) of the vehicles that have arrived at the tollgate.

[0017] Vehicles attempting to enter the toll road U from the general road arrive at the entrance toll booth G2. The vehicle travels on the inflow lane L2 and arrives at the entrance toll booth G2. After passing through the entrance toll booth G2, the vehicle travels on the toll road U. Although not shown in the figure, each lane of the entrance toll booth G2 is provided with a wireless communication device for performing wireless communication with the in-vehicle unit C of the arriving vehicle A, and a vehicle type discrimination device capable of specifying the vehicle type classification based on the detection result of the characteristics (number of axles, etc.) of the vehicle A.

[0018] Also, vehicles attempting to exit the toll road U to the general road arrive at the exit toll booth G3. The vehicle travels on the toll road U and arrives at the exit toll booth G3. After passing through the exit toll booth G3, the vehicle travels on the outflow lane L3 and returns to the general road. Each lane of the exit toll booth G3 is provided with a wireless communication device for performing charging processing on the arriving vehicle by wireless communication, a roadside display for immediately notifying the collected toll amount, and the like.

[0019] The main line toll booth G4 is a toll booth provided on the main line LM and is also called an aggregated toll booth. At the main line toll booth G4, vehicles traveling on the main line LM of the toll road U pass through. Each lane of the main line toll booth G4 is provided with a wireless communication device and a vehicle type discrimination device similar to those of the entrance toll booth G2.

[0020] The toll road U is provided with an entrance FF lane L2F. The entrance FF lane L2F is an FF (free flow) lane and is an inflow lane without a toll gate. Although a wireless communication device is provided on the roadside of the entrance FF lane L2F, a vehicle type discrimination device is not provided.

[0021] Next, the monitoring system 9 will be described. As shown in FIG. 1, the monitoring system 9 includes a monitoring device 1 and a toll booth device 2.

[0022] The monitoring device 1 is communicably connected to the tollgate devices 2 installed at each tollgate and FF lane of the toll road U via a wide area communication network, and creates incident information based on the tollgate notification information sequentially received from each tollgate device 2. Then, the monitoring device 1 distributes the incident information to each tollgate device 2. Details of the tollgate notification information and the incident information will be described later. Note that the monitoring device 1 may be a central charging processing device in an electronic toll collection system. The central charging processing device collects vehicle information regarding vehicles that have passed through each tollgate from each tollgate device 2, and distributes information regarding all vehicles traveling on the toll road U to each tollgate device 2. Then, the tollgate device 2 refers to the distributed vehicle information and performs charging processing on the vehicle.

[0023] The tollgate device 2 transmits tollgate notification information including vehicle information regarding the vehicle that has arrived at the tollgate or device information regarding various devices (such as a wireless communication device and a vehicle type discrimination device) installed at the tollgate to the monitoring device 1. In addition, the tollgate device 2 stores the incident information distributed from the monitoring device 1 in a local (within its own device) recording medium. The tollgate device 2 refers to the incident information and performs processing corresponding to the incident.

[0024] Note that the tollgate device according to the present embodiment is a charging processing device (an entrance charging processing device 2A, an exit charging processing device 2B, a main line charging processing device 2C, an entrance FF charging processing device 2D) installed at each tollgate. The entrance charging processing device 2A, the exit charging processing device 2B, and the main line charging processing device 2C are installed at the entrance tollgate G2, the exit tollgate G3, and the main line tollgate G4, respectively. When there are a plurality of lanes at these tollgates, the charging processing device is installed for each lane. In addition, the entrance FF charging processing device 2D is installed on the entrance FF lane L2F. The charging processing device performs various processes related to the charging of tolls for vehicles passing through the lanes of the toll booth. For example, the charging processing device generates vehicle information (toll booth notification information) including vehicle identification information (e.g., in-vehicle unit ID) acquired from the in-vehicle unit C through a wireless communication device and vehicle type classification information determined by the vehicle type discrimination device, and transmits it to the monitoring device 1. Details of the vehicle information will be described later. Note that at locations where the vehicle type discrimination device is not installed (e.g., the exit toll booth G3 and the entrance FF lane L2F), the vehicle information transmitted by the charging processing device does not include the vehicle type classification information determined by the vehicle type discrimination device.

[0025] (Functional Configuration of Monitoring Device) FIG. 2 is a diagram showing the functional configuration of the monitoring device according to the first embodiment. As shown in FIG. 2, the monitoring device 1 includes a CPU 10, a memory 11, a communication interface 12, an input / output interface 13, and a recording medium 14.

[0026] The CPU 10 is a processor that exhibits various functions by operating according to a program prepared in advance. The functions of the CPU 10 will be described later. The memory 11 is a so-called main storage device and has a storage area necessary for the operation of the CPU 10. The communication interface 12 is a connection interface for communicably connecting to each charging processing device via a wide area communication network. The input / output interface 13 is a connection interface for connecting to devices such as a display device 15 and an input device 16. The display device 15 is a monitor such as a liquid crystal display. The input device 16 is an input device such as a keyboard and a mouse. Note that the display device 15 and the input device 16 may be devices integrally formed like a touch panel. The recording medium 14 is a so-called auxiliary storage device and is a large-capacity storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive). In this embodiment, a full incident information table T1 and a setting table T2 referred to when creating incident information are recorded in the recording medium 14.

[0027] Next, the functions of the CPU 10 of the monitoring device 1 will be described.

[0028] The CPU 10 operates according to a pre-prepared program to exhibit functions as a receiving unit 101, a creating unit 102, and a distribution unit 103.

[0029] The receiving unit 101 receives tollgate notification information from each tollgate device 2. The tollgate notification information includes vehicle information regarding vehicles that have passed through the tollgate or device information regarding devices installed at the tollgate.

[0030] When an incident is detected, the creating unit 102 creates incident information including incident type information indicating the type of the incident. The creating unit 102 creates incident information based on the information input by the monitor through the input device 16.

[0031] For example, when the monitor checks the video of a tollgate surveillance camera (described later) displayed on the display device 15 and discovers an incident such as illegal passage of vehicle A, or when the monitor discovers or predicts an incident such as a traffic stop due to an accident or weather, the monitor performs an operation of reporting the incident (input operation of incident type information, etc.) through the input device 16 of the monitoring device 1. Thereby, the monitoring device 1 can detect, through the operation of the monitor, incidents that are difficult to automatically detect by the sensor devices of the vehicle type discrimination device 26 (for example, illegal passage of a modified vehicle, passage of a vehicle damaged by colliding with a tollgate device, traffic stop, etc.), and create incident information.

[0032] Note that when the incident type information is included in the vehicle information or device information received from each tollgate device 2, the creating unit 102 may automatically create incident information including the incident type information.

[0033] In addition, the creation unit 102 creates and updates the entire incident information table T1 that aggregates incident information. When the incident recorded in the entire incident information table T1 is resolved, the creation unit 102 excludes the incident information related to the incident from the entire incident information table T1.

[0034] The distribution unit 103 distributes the incident information created by the creation unit 102 to each tollgate device 2. In addition, when the creation unit 102 excludes incident information from the entire incident information table T1, the distribution unit 103 distributes incident exclusion information instructing the exclusion of the incident information to each tollgate device 2.

[0035] (Functional configuration of the tollgate device) FIG. 3 is a diagram showing the functional configuration of the tollgate device according to the first embodiment. As shown in FIG. 3, the tollgate device 2 includes a CPU 20, a memory 21, a communication interface 22, a roadside device interface 23, and a recording medium 24.

[0036] The CPU 20 is a processor that exhibits various functions by operating according to a pre-prepared program. The functions of the CPU 20 will be described later. The memory 21 has a storage area necessary for the operation of the CPU 20. The communication interface 22 is a connection interface for communicably connecting to the monitoring device 1 via a wide area communication network. The roadside device interface 23 is a connection interface for communicating with roadside devices (wireless communication device 25, vehicle type discrimination device 26, monitoring camera 27, guidance display device 28) provided in each lane of the tollgate. The recording medium 24 is a local recording medium provided in the tollgate device 2 and is a large-capacity storage device such as an HDD or an SSD. In the present embodiment, the incident information distributed from the monitoring device 1 is recorded in the recording medium 24.

[0037] Next, the roadside devices (wireless communication device 25, vehicle type discrimination device 26, surveillance camera 27, guidance display device 28) connected to the tollgate device 2 will be described.

[0038] The wireless communication device 25 performs wireless communication using DSRC (Dedicated Short Range Communications) with the in-vehicle unit C (Fig. 1) of the vehicle A that has arrived at the tollgate, and acquires various types of information (in-vehicle unit ID, IC card information, license plate information, etc.) recorded in the in-vehicle unit C. The various types of information recorded in the in-vehicle unit C are vehicle identification information that can uniquely identify the vehicle.

[0039] The vehicle type discrimination device 26 is a device that can identify the vehicle type classification of the traveling vehicle A. The vehicle type discrimination device 26 detects the characteristics (such as the number of axles) of the vehicle A passing through the lane through sensor devices such as footboards and vehicle detectors, and specifies the vehicle type classification information of the vehicle based on the detected characteristics. Further, the vehicle type discrimination device 26 may detect the characteristics (such as vehicle height, vehicle length, vehicle width, axle weight, gross weight, etc.) of the vehicle A through sensor devices such as laser sensors and weigh scales.

[0040] The surveillance camera 27 is a camera for monitoring the lanes of the tollgate, and photographs the vehicle A passing through the lane. The video captured by the surveillance camera 27 is displayed in real time on the display device 15 of the monitoring device 1.

[0041] The guidance display device 28 is an electric bulletin board or the like for notifying users at the tollgate under the control of the tollgate device 2. For example, as one of the processes corresponding to an incident by the tollgate device 2, the guidance display device 28 displays guidance information regarding the incident to the users.

[0042] Next, the functions of the CPU 20 of the tollgate device 2 will be described.

[0043] The CPU 20 operates according to a pre-prepared program, thereby exhibiting functions as a recording processing unit 201, a vehicle information acquisition unit 202, a device abnormality detection unit 203, a transmission unit 204, and an incident processing unit 205.

[0044] The recording processing unit 201 records the incident information D3 distributed from the monitoring device 1 on the local recording medium 24. Further, when incident exclusion information is distributed from the monitoring device 1, the recording processing unit 201 deletes the corresponding incident information D3 from the recording medium 24.

[0045] The vehicle information acquisition unit 202 acquires the vehicle information of the vehicle that has arrived at the tollgate through the wireless communication device 25 and the vehicle type discrimination device 26. The vehicle information acquired here includes vehicle identification information that can identify the vehicle and vehicle type classification information determined using detection results such as the number of axles of the vehicle. In addition, the vehicle information acquired from the vehicle type discrimination device 26 may further include vehicle characteristic information (such as vehicle height, vehicle length, vehicle width, axle weight, gross weight, etc.). If at least one of the vehicle characteristic information of vehicle A exceeds the upper limit value defined for the toll road U, the vehicle information acquisition unit 202 may determine that vehicle A has made an illegal passage. Note that at tollgates where the vehicle type discrimination device 26 is not installed, the vehicle information acquired by the vehicle information acquisition unit 202 does not include vehicle type classification information and vehicle characteristic information.

[0046] The device abnormality detection unit 203 detects the presence or absence of abnormalities such as malfunctions of various devices (especially the wireless communication device 25 and the vehicle type discrimination device 26) installed at the tollgate.

[0047] The transmission unit 204 transmits tollgate notification information to the monitoring device 1. The tollgate notification information is vehicle information including the vehicle identification information of vehicle A passing through the tollgate, or device information indicating the state of the devices installed at the tollgate. When the transmission unit 204 detects the presence of vehicle A passing through the lane of the tollgate, it transmits the vehicle information of vehicle A to the monitoring device 1. Note that when the vehicle information acquisition unit 202 detects an illegal passage of vehicle A (such as an axle weight overrun, etc.), the transmission unit 204 transmits vehicle information including incident type information indicating the illegal passage to the monitoring device 1. Further, when the device abnormality detection unit 203 detects an abnormality of the device, the transmission unit 204 transmits device information including the identification information of the device and the incident type information indicating the occurrence of the device abnormality to the monitoring device 1. Note that when the device abnormality detection unit 203 detects the recovery of the device (when no abnormality is detected), the transmission unit 204 may transmit device information including the identification information of the device and the incident type information indicating the device recovery to the monitoring device 1.

[0048] The incident processing unit 205 performs processing according to the incident information D3 recorded on the recording medium 24.

[0049] (Example of tollgate notification information) FIG. 4 is a first diagram showing an example of tollgate notification information according to the first embodiment. FIG. 5 is a second diagram showing an example of tollgate notification information according to the first embodiment. Hereinafter, with reference to FIGS. 4 and 5, the contents of the tollgate notification information (vehicle information D1, device information D2) sequentially acquired by the tollgate device 2 at each tollgate and transmitted to the monitoring device 1 will be described in detail.

[0050] As shown in FIG. 4, the vehicle information D1 includes "vehicle identification information" (in this embodiment, "on-vehicle unit ID"), "tollgate number", "lane number", "processing date and time", "IC card information", "vehicle type classification information", "license plate information", "incident type information", "vehicle image data", and the like.

[0051] Among the vehicle information D1 acquired by the vehicle information acquisition unit 202 of the tollgate device 2, information such as "vehicle identification information (in-vehicle device ID)", "IC card information", and "license plate information" is obtained through wireless communication with the in-vehicle device C by the wireless communication device 25. Also, the "vehicle type classification information" is vehicle type classification information obtained through the vehicle type discrimination device 26. The "incident type information" is incident type information indicating "illegal passage" when the tollgate device 2 detects illegal passage of vehicle A. Note that when the tollgate device 2 does not detect illegal passage, the "incident type information" is not included. The "image data" is image data captured by the surveillance camera 27 while the presence of the vehicle is detected by the vehicle detector. The supervisor may display the image data (past video) included in the vehicle information D1 on the display device 15 of the surveillance device 1 to confirm the presence or absence of incidents such as illegal passage of vehicle A.

[0052] At locations where the vehicle type discrimination device 26 is not installed, that is, at the exit tollgate G3 and the tollgate device 2 installed in the entrance FF lane L2F, the vehicle information acquisition unit 202 cannot acquire vehicle type classification information and vehicle feature information. Therefore, at such locations, the vehicle information D1 acquired by the vehicle information acquisition unit 202 does not include "vehicle type classification information" and "incident type information". For vehicles entering the toll road U from the entrance FF lane L2F, when passing through the main line tollgate G4 later, the tollgate device 2 (main line charging processing device 2C) of the main line tollgate G4 acquires vehicle type classification information and vehicle feature information. Therefore, when the vehicle passes through the main line tollgate G4, the surveillance device 1 can acquire the vehicle information D1 including the "vehicle type classification information" and "incident type information" of this vehicle.

[0053] Also, as shown in FIG. 5, the device information D2 includes "tollgate number", "lane number", "detection date and time", "device identification information", "incident type information", etc. The "device identification information" is information that can identify, for example, the device type (such as a wireless communication device, a vehicle type discrimination device, a pedal, etc.). The device can be uniquely identified by the combination of the "tollgate number", "lane number", and "device identification information". When the tollgate device 2 detects an abnormality in the device, incident type information indicating "device abnormality occurred" is input to the "incident type information", and when recovery from the abnormality is detected, incident type information indicating device recovery is input.

[0054] (Example of incident information and all incident information table) FIG. 6 is a diagram showing an example of incident information according to the first embodiment. FIG. 7 is a diagram showing an example of the all incident information table according to the first embodiment. FIG. 8 is a diagram showing an example of the setting table according to the first embodiment. Hereinafter, with reference to FIGS. 6 to 8, the details of the data contents of the incident information D3 and the all incident information table T1 created by the monitoring device 1 will be described in detail.

[0055] As shown in FIG. 6, the incident information D3 includes "ID", "tollgate number", "lane number", "occurrence date and time", "incident type information", "device identification information", "vehicle identification information", "instruction information", "target tollgate number", etc.

[0056] Among the information included in the incident information D3, the "tollgate number", "lane number", "occurrence date and time or detection date and time", "device identification information", and "vehicle identification information" are the information included in the vehicle information D1 or the device information D2 obtained from the tollgate device 2. The "ID" is identification information (such as a serial number) attached to each of the incident information D3, and is automatically input when the creation unit 102 creates the incident information D3. The "incident type information" is information input by the monitor according to the incident, or information included in the vehicle information D1 or the device information D2.

[0057] The "instruction information" and "target tollgate number" included in the incident information D3 are information that specifies what processing is to be performed at which tollgate corresponding to the incident type information. The "instruction information" and "target tollgate number" are manually input by the supervisor via the input device 16 of the monitoring device 1.

[0058] Note that in the setting table T2 shown in FIG. 8, the "instruction information (processing to be performed at the tollgate)" and "target tollgate information (tollgate at which the processing is to be performed)" corresponding to the incident type information may be set in advance. In this case, the "instruction information" and "target tollgate information" associated with the incident type information input by the supervisor may be automatically read from the setting table T2 and input into the incident information D3. Similarly, when the "incident type information" is included in the vehicle information D1 and the device information D2, the "instruction information" and "target tollgate information" associated with this incident type information may be automatically read from the setting table T2 and input into the incident information D3. Also, the "target tollgate information" in the setting table T2 is specified, for example, as "all tollgates on the downstream side", "all entrance tollgates or entrance FF lanes on the upstream side", "n exit tollgates on the downstream side" based on the tollgate where the incident is detected (the tollgate specified by the "tollgate number" in the incident information D3). At this time, the "target tollgate number" in the incident information D3 is automatically set based on the "tollgate number" in the incident information D3 and the "target tollgate information" in the setting table T2.

[0059] Also, FIG. 8 shows the content of the entire incident information table T1 created by the creation unit 102 of the monitoring device 1. As shown in FIG. 8, the entire incident information table T1 is formed by aggregating the incident information D3 created by the creation unit 102 of the monitoring device 1.

[0060] (Processing flow of the monitoring device) FIG. 9 is a diagram showing a processing flow of the monitoring device according to the first embodiment. Hereinafter, with reference to FIG. 9, the processing flow executed by the monitoring device 1 will be described in detail. The processing flow shown in FIG. 9 is repeatedly executed by the monitoring device 1 at regular intervals (for example, at a cycle of once every few seconds, minutes, or tens of minutes, which is shorter than the shortest time expected from the entrance to the exit on the toll road).

[0061] First, the receiving unit 101 of the monitoring device 1 acquires tollgate notification information from each tollgate (step S11). Specifically, each time a vehicle arrives at a tollgate, the receiving unit 101 receives vehicle information D1 (FIG. 4) from the tollgate device 2. In addition, each time a device abnormality or device recovery is detected at each tollgate, the receiving unit 101 receives device information D2 (FIG. 5) from the tollgate device 2.

[0062] Next, the creation unit 102 of the monitoring device 1 determines whether an incident has been detected (step S12).

[0063] For example, the monitor monitors the video of the tollgate surveillance camera 27 through the display device 15 of the monitoring device 1. When the monitor discovers illegal passage of vehicle A or the like from the video, or predicts that it is necessary to stop traffic (close the tollgate) based on weather information or the like, the monitor performs an operation for reporting an incident (for example, pressing an incident report button) through the input device 16 of the monitoring device 1. When the monitor performs an operation for reporting an incident, the creation unit 102 determines that an incident has been detected (step S12; YES).

[0064] In addition, when the event identification information is included in the vehicle information D1 or the device information D2 acquired from the tollgate device 2, the creation unit 102 may determine that an incident has been detected (step S12; YES).

[0065] Next, the creation unit 102 creates incident information D3 regarding the detected incident (step S13).

[0066] When the monitor performs an incident reporting operation, the monitoring device 1 receives input of incident type information and the like through the input device 16. Then, the creation unit 102 creates incident information D3 (Fig. 6) based on the input information. For example, the creation unit 102 creates incident information D3 including the "tollgate number", "lane number", "processing date and time" or "detection date and time", and "device identification information" or "vehicle identification information" of the tollgate notification information (vehicle information D1 or device information D2) selected by the monitor. In addition, the creation unit 102 adds the "instruction information" and "target tollgate number" input from the monitor to the created incident information D3. Note that the monitor may input arbitrary information for the "instruction information" and "target tollgate number", or may select and input the corresponding one from the setting table T2 (Fig. 8) according to the incident type information. Also, when the monitor inputs incident type information, the creation unit 102 may automatically select the corresponding "instruction information" and "target tollgate information" from the setting table T2 (Fig. 8) and add them to the incident information D3. Note that the "instruction information" in the incident information D3 may have different contents for each target tollgate.

[0067] Next, the distribution unit 103 of the monitoring device 1 distributes the created incident information D3 to the target tollgate (step S14). Each tollgate device 2 records the received incident information D3 on the recording medium 24.

[0068] Also, when no incident is detected (step S12; NO), the creation unit 102 further determines whether the resolution of the incident has been detected (step S15).

[0069] For example, when the monitor knows from the video of the monitoring camera 27 or the like that the incident recorded in the entire incident information table T1 has been resolved, the monitor performs an operation (for example, pressing the incident exclusion button) to report the incident resolution through the input device 16 of the monitoring device 1. When the operator performs an operation for incident resolution reporting, the creation unit 102 determines that the incident has been resolved (step S15; YES).

[0070] In addition, when the event identification information related to incident resolution is included in the vehicle information D1 or the device information D2 acquired from the tollgate device 2, the creation unit 102 may determine that the incident has been resolved (step S15; YES). For example, when receiving the vehicle information D1 indicating that the passage of an illegally passing vehicle (exiting from the toll road U) has been detected from the tollgate device 2 at the exit tollgate G3, it is determined that the incident related to the illegally passing vehicle has been resolved. Also, when the device information D2 includes the incident type information indicating device recovery, it is determined that the incident related to the abnormality of this device has been resolved.

[0071] Then, the creation unit 102 creates incident exclusion information related to the incident for which resolution has been detected (step S16).

[0072] Next, the distribution unit 103 distributes the created incident exclusion information to the target tollgate (step S17). Each tollgate device 2 deletes the incident information D3 corresponding to the received incident exclusion information from the recording medium 24. For example, the incident exclusion information includes the "ID" of the corresponding incident information D3, and the tollgate device 2 deletes the incident information D3 associated with the ID included in the incident exclusion information.

[0073] If neither the occurrence nor the resolution of the incident is detected (step S12; NO and step S15; NO), the monitoring device 1 ends the process without creating incident information and incident exclusion information.

[0074] (Processing flow of tollgate device 1) FIG. 10 is a first diagram showing the processing flow of the tollgate device according to the first embodiment. FIG. 11 is a first diagram for explaining the functions of the tollgate device according to the first embodiment. Hereinafter, with reference to FIGS. 10 and 11, the processing flow executed by the tollgate device 2 when incident information or incident exclusion information is distributed from the monitoring device 1 will be described in detail. Note that the processing flow shown in FIG. 10 is repeatedly executed each time the tollgate device 2 receives incident information or incident exclusion information.

[0075] First, the recording processing unit 201 of the tollgate device 2 receives the incident information D3 or the incident exclusion information distributed from the monitoring device 1 (step S21).

[0076] When the received information is incident information D3 (step S22; YES), the recording processing unit 201 records the received incident information D3 on the recording medium 24 (step S23).

[0077] In addition, when there is a process to be immediately executed by referring to the instruction information of the incident information D3, the incident processing unit 205 of the tollgate device 2 executes the specified process (step S24).

[0078] When the received information is incident exclusion information (step S22; NO), the recording processing unit 201 deletes the corresponding incident information D3 from the recording medium 24 (step S25).

[0079] In addition, when there is a process being executed based on the instruction information of the deleted incident information D3, the incident processing unit 205 ends the execution of this process (step S26).

[0080] For example, as shown in FIG. 11, it is assumed that a traffic stop is required on a part of the toll road U. Then, based on the input operation of the monitor, the monitoring device 1 creates incident information D3 regarding the traffic stop and distributes it to the target tollgate. This incident information D3 includes instruction information for specifying different processes for each target tollgate as follows. Process A: At the entrance toll gate G2a, the exit toll gate G3b, and the entrance toll gate G2a on the upstream side of the traffic stop section, which are included in the traffic stop section, perform the process of closing the toll gate. Process B: At the exit toll gate G3a upstream of the traffic stop section, perform the process of allowing vehicles to exit for free.

[0081] When the toll gate devices 2 of the entrance toll gate G2a, the entrance toll gate G2b, and the exit toll gate G3b each receive this incident information D3 (steps S21, S22; YES), they record it on the recording medium 24 (step S23). Also, the process (Process A) specified by the instruction information included in the incident information D3 needs to be performed constantly. For this reason, the incident processing unit 205 of the toll gate device 2 performs the closing process of the toll gate specified by the instruction information (step S24). For example, the incident processing unit 205 closes the ETC gates in all lanes and performs a process of displaying guidance such as "Traffic Stop" and "Toll Gate Closed" on the guidance display device 28.

[0082] On the other hand, when the toll gate device 2 of the exit toll gate G3a receives this incident information D3 (step S22; YES), it records it on the recording medium 24 (step S23). Also, the process (Process B) specified by the instruction information included in the incident information D3 does not need to be performed constantly and may be performed when a vehicle is detected. For this reason, the incident processing unit 205 of the toll gate device 2 does not perform the process at this point and performs the specified process when a vehicle is detected according to the processing flow shown in FIG. 12 described later.

[0083] Also, when the traffic stop is lifted, the monitoring device 1 creates incident exclusion information for the traffic stop based on the input operation of the monitor and distributes it to the target toll gate.

[0084] When the toll gate devices 2 of the entrance toll gate G2a, the entrance toll gate G2b, and the exit toll gate G3b receive this incident exclusion information (Steps S21, S22; NO), they delete the corresponding incident information D3 from the recording medium 24 (Step S25). Also, they end the process (toll gate closing process) being performed based on the instruction information of the incident information D3 (Step S26). For example, the incident processing unit 205 operates the ETC gates in all lanes and performs a process of displaying a guidance such as "Passable" on the guidance display device 28.

[0085] On the other hand, when the toll gate device 2 of the exit toll gate G3a receives this incident exclusion information (Steps S21, S22; NO), it deletes the corresponding incident information D3 from the recording medium 24 (Step S25). If there is no process being performed according to the instruction information of the incident information D3, the toll gate device 2 ends the process here.

[0086] (Processing flow of toll gate device 2) FIG. 12 is a second diagram showing the processing flow of the toll gate device according to the first embodiment. FIG. 13 is a first diagram for explaining the functions of the toll gate device according to the first embodiment. Hereinafter, with reference to FIGS. 12 and 13, the processing flow executed by the toll gate device 2 when a vehicle arrives at the toll gate will be described in detail. Note that the processing flow shown in FIG. 12 is repeatedly executed by the toll gate device 2 each time the passage of vehicle A is detected.

[0087] First, the toll gate device 2 detects a vehicle traveling in the toll gate lane (Step S31).

[0088] Next, the vehicle information acquisition unit 202 of the tollgate device 2 acquires vehicle information D1 including vehicle specific information (in-vehicle unit ID) of the vehicle through the wireless communication device 25 and the vehicle type discrimination device 26 (step S32). At this time, when the vehicle information acquisition unit 202 detects that the axle weight of the vehicle exceeds the upper limit value defined on the toll road U based on the vehicle characteristic information acquired from the vehicle type discrimination device 26, the incident type information indicating "illegal passing vehicle" may be included in the vehicle information D1.

[0089] Next, the tollgate device 2 determines whether incident information D3 related to the vehicle is recorded on the recording medium 24 (step S33).

[0090] When the incident information D3 associated with the vehicle specific information of the vehicle is not recorded (step S33; NO), the transmission unit 204 of the tollgate device 2 transmits the vehicle information D1 of this vehicle to the monitoring device 1 (step S35).

[0091] On the other hand, when the incident information D3 associated with the vehicle specific information of the vehicle is recorded (step S33; YES), the incident processing unit 205 of the tollgate device 2 executes the process specified in the "instruction information" of the incident information D3 (step S34). For example, as in the example of FIG. 11, it is assumed that at the exit tollgate G3a, a process of allowing the vehicle to exit for free is specified. At this time, the incident processing unit 205 of the tollgate device 2 installed at the exit tollgate G3a performs a charging process by making the charging amount of vehicle A free. Thereafter, the transmission unit 204 of the tollgate device 2 transmits the vehicle information D1 of this vehicle to the monitoring device 1 (step S35).

[0092] Also, for example, as shown in FIG. 13, it is assumed that vehicle A is detected at the entrance tollgate G2a (step S31). At this time, the vehicle information acquisition unit 202 of the tollgate device 2 installed at the entrance tollgate G2a acquires the vehicle information D1 of vehicle A through the wireless communication device 25 and the vehicle type discrimination device 26 (step S32). When the incident processing unit 205 of the tollgate device 2 does not record incident information D3 associated with the vehicle identification information of vehicle A (step S33; NO), it creates the vehicle information D1 of this vehicle A and transmits it to the monitoring device 1 (step S35).

[0093] Also, assume that the monitor is monitoring the video of the surveillance camera 27 at the entrance tollgate G2a via the display device 15 of the monitoring device 1. When the monitor determines from the video that vehicle A passing through the entrance tollgate G2a is a modified vehicle (illegal passing vehicle), an incident report operation is performed through the monitoring device 1, and incident information D3 regarding the vehicle A is created. This incident information D3 includes information instructing the implementation of the enforcement process for the vehicle A, with all the exit tollgates G3 (exit tollgates G3b and G3c in Fig. 11) located downstream of the entrance tollgate G2a where the vehicle A entered as the target tollgates. This incident information D3 is distributed to the tollgate devices 2 at the target tollgates, namely the exit tollgates G3b and G3c.

[0094] Then, assume that the vehicle A determined to be an illegal passing vehicle arrives at the exit tollgate G3c. When the tollgate device 2 installed at the exit tollgate G3c detects the vehicle A (step S31), it acquires the vehicle information D1 of this vehicle A through the wireless communication device 25 and the vehicle type discrimination device 26 (step S32). Also, since the incident processing unit 205 of the tollgate device 2 has recorded the incident information D3 associated with the vehicle identification information of this vehicle A (step S33; YES), it performs processing according to the instruction information in the incident information D3 (step S34). In this example, the incident processing unit 205 performs the enforcement process for the vehicle A specified by the instruction information. The enforcement process is, for example, closing the ETC gate to restrict the vehicle A from exiting the exit tollgate G3c, charging an additional toll to the vehicle A, reporting to the enforcement agency, etc.

[0095] In step 32 of FIG. 12, the vehicle information acquisition unit 202 may automatically detect unauthorized passage such as over axle load based on the vehicle characteristic information acquired from the vehicle type discrimination device 26. In this case, incident identification information indicating unauthorized passage is added to the vehicle information D1 and transmitted to the monitoring device 1. The monitoring device 1 may automatically create and distribute incident information D3 as shown in FIG. 13 based on this vehicle information D1.

[0096] (Tollgate device processing flow 3) FIG. 14 is a third diagram showing the processing flow of the tollgate device according to the first embodiment. FIG. 15 is a third diagram for explaining the functions of the tollgate device according to the first embodiment. Hereinafter, with reference to FIGS. 12 and 13, the processing flow executed by the tollgate device 2 when a device abnormality or device recovery is detected will be described in detail. Note that the processing flow shown in FIG. 14 is periodically and repeatedly executed by the tollgate device 2.

[0097] First, the device abnormality detection unit 203 of the tollgate device 2 monitors the state of each device installed at the tollgate (step S41).

[0098] When the device abnormality detection unit 203 detects a device abnormality (step S42; YES), the transmission unit 204 of the tollgate device 2 transmits device information D2 indicating the occurrence of the device abnormality to the monitoring device 1 (step S43). For example, the device abnormality detection unit 203 periodically outputs a signal to each device and detects an abnormality when a response signal to the signal cannot be received for a predetermined time or more.

[0099] On the other hand, when the device abnormality detection unit detects that the device abnormality has been resolved (step S42; NO and step S45; YES), the transmission unit 204 transmits device information D2 indicating device recovery to the monitoring device 1 (step S46). For example, when a response signal from the device can be received due to repair, replacement, restart, etc. of the device, the device abnormality detection unit 203 detects the recovery of this device.

[0100] For example, as shown in FIG. 15, assume that the device abnormality detection unit 203 of the tollgate device 2 installed at the entrance tollgate G2a detects that the vehicle type discrimination device 26 has failed and the vehicle type classification information of the vehicle A passing through the entrance tollgate G2a cannot be obtained (step S42; YES). In this case, the transmission unit 204 transmits device information D2 indicating the occurrence of a device abnormality (failure of the vehicle type discrimination device) to the monitoring device 1 (step S43). Then, based on this device information D2, the monitoring device 1 automatically or according to the input operation of the monitor creates incident information D3 regarding the failure of the vehicle type discrimination device and distributes it to the target tollgate. In the example of FIG. 15, incident information D3 that designates a process of stopping the vehicles that have passed through the entrance tollgate G2a is distributed to all the exit tollgates G3 (G3b, G3c) on the downstream side of the entrance tollgate G2a.

[0101] Also, the tollgate devices 2 of the exit tollgates G3b and G3c that have received this incident information D3 perform the process specified when detecting the vehicle A that has passed through the entrance tollgate G2a according to the processing flow shown in FIG. 12. In the example of FIG. 13, when the incident processing unit 205 of the tollgate device 2 of the exit tollgate G3c detects the vehicle A that has passed through the entrance tollgate G2a, it performs a process of closing the ETC gate and stopping the vehicle. Also, the incident processing unit 205 performs a process of notifying the toll collector at the exit tollgate G3c to visually confirm the vehicle type classification information of the vehicle A and perform the charging process. The toll collector responds to the charging process of the vehicle A according to this notification. Note that information indicating which entrance tollgate G2 the vehicle A has passed through (entrance tollgate number) is written, for example, in the in-vehicle unit C when the vehicle A passes through the entrance tollgate G2. At the exit tollgate G3c, the vehicle information acquisition unit 202 of the tollgate device 2 acquires the entrance tollgate number from the in-vehicle unit C of the vehicle A through the wireless communication device 25. Further, the monitoring device 1 may distribute the vehicle information D1 (including the passed entrance tollgate number and vehicle identification information) collected from the entrance tollgate G2 to each exit tollgate G3. In this case, the tollgate device 2 at the exit tollgate G3c refers to the vehicle information D1 associated with the vehicle identification information obtained from the in-vehicle unit C of vehicle A to identify which entrance tollgate G2 this vehicle A has passed through.

[0102] (Function, effect) As described above, when an incident is detected, the monitoring device 1 according to the first embodiment creates incident information D3 including incident type information and distributes it to the tollgate device 2 at the target tollgate. By doing so, when an incident such as a traffic stop or illegal passage occurs, the monitoring device 1 can quickly share this among the relevant tollgates. As a result, at each tollgate, it becomes possible to immediately take measures against this incident.

[0103] Also, the tollgate device 2 performs processing according to the incident information distributed from the monitoring device 1. As a result, when an incident occurs, the tollgate device 2 can quickly take measures against the incident.

[0104] (Modification example of the first embodiment) In the tollgate device 2 according to the first embodiment, the incident processing unit 205 performs processing based on the instruction information included in the incident information D3 distributed from the monitoring device 1, but it is not limited to this. In other embodiments, the incident processing unit 205 may itself select and perform processing according to the incident type information included in the incident information D3. In this case, the instruction information in the incident information D3 is omitted.

[0105] For example, a preset table T2 (FIG. 8) is recorded in the recording medium 24 of each tollgate device 2. The incident processing unit 205 refers to the instruction information and the target tollgate information associated with the incident type information included in the incident information D3, and selects the process to be performed by its own device from the instruction information.

[0106] Also, although the monitoring device 1 according to the first embodiment distributes the incident information D3 only to the tollgate device 2 of the target tollgate, it is not limited to this. In other embodiments, the monitoring device 1 may distribute the incident information D3 to the tollgate devices 2 of all tollgates. At this time, the monitoring device 1 may distribute the entire incident information table T1 and its difference information (a list of added incident information and incident exclusion information) to all tollgate devices 2. In this case, the incident processing unit 205 of each tollgate device 2 refers to the target tollgate number included in the incident information D3 or the target tollgate information in the setting table T2, and performs the process when the tollgate where its own device is installed corresponds to the target tollgate.

[0107] In each of the above-described embodiments, the processes executed by the monitoring device 1 and the tollgate device 2 are stored in a computer-readable recording medium in the form of a program, and the computer reads and executes this program to perform the above-described various processes. The computer-readable recording medium refers to a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, etc. Also, this computer program may be distributed to a computer via a communication line, and the computer that has received this distribution may execute the program.

[0108] The above program may be for realizing a part of the functions described above. Furthermore, it may be a so-called difference file (difference program) that can realize the functions described above in combination with a program already recorded in the computer system.

[0109] As described above, some embodiments according to the present disclosure have been explained. However, all of these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention, as well as in the invention described in the claims and the equivalent scope thereof.

[0110] <Appendix> The monitoring device, tollgate device, monitoring system, monitoring method, and program described in each embodiment are understood as follows, for example.

[0111] (1) In a first aspect, the monitoring device 1 includes a creation unit 102 that creates incident information D3 including incident type information indicating the type of an incident when the incident is detected, and a distribution unit 103 that distributes the incident information D3 to the tollgate device 2 of the tollgate that performs processing corresponding to the incident type information.

[0112] By doing so, when an incident such as a traffic stop or illegal passage occurs, the monitoring device 1 can quickly share this among relevant tollgates. As a result, at each tollgate, it becomes possible to immediately take measures against this incident.

[0113] (2) In a second aspect, the monitoring device 1 includes a receiving unit 101 that receives vehicle information D1 including vehicle identification information of a vehicle passing through the tollgate or device information D2 indicating the state of a device installed at the tollgate from the tollgate device 2, and the creation unit 102 creates incident information D3 based on the vehicle information D1 or the device information D2.

[0114] By doing so, the monitoring device 1 can create the incident information D3 using the information included in the vehicle information D1 and the device information D2 collected from each tollgate.

[0115] (3) In the third aspect, when an incident (such as illegal passage) by a vehicle is detected at a tollgate, the vehicle information D1 includes incident type information corresponding to the incident. When an abnormal incident occurs in the equipment installed at the tollgate, the equipment information D2 includes incident type information corresponding to the incident. The creation unit 102 refers to a setting table T2 in which processing corresponding to each of a plurality of incident type information is preset, and creates incident information D3 including instruction information designating the processing corresponding to the incident type information included in the vehicle information D1 or the equipment information D2.

[0116] By doing so, the monitoring device 1 can automatically create incident information D3 regarding the incident detected at the tollgate based on the vehicle information D1 and the equipment information D2. For example, for an illegal vehicle (such as over axle load) that can be detected by a sensor device, the monitoring device 1 can automatically create incident information D3 and distribute it to each tollgate without the need for constant monitoring by a supervisor.

[0117] (4) In the fourth aspect, the incident information D3 includes different instruction information according to the tollgate.

[0118] By doing so, the monitoring device 1 can cause each tollgate to perform appropriate processing for the incident according to whether the tollgate is an entrance tollgate, an exit tollgate, or the like.

[0119] (5) In the fifth aspect, the creation unit 102 receives an input of incident type information by a supervisor and creates incident information D3.

[0120] By doing so, the monitoring device 1 can also create incident information D3 based on the information input by the supervisor for an incident that is difficult to automatically detect by the sensor device at the tollgate, such as a modified vehicle.

[0121] (6) In the sixth aspect, when the incident is resolved, the distribution unit 103 distributes incident exclusion information instructing the exclusion of incident information D3 related to the incident to the tollgate device 2 at the tollgate.

[0122] By doing so, the monitoring device 1 can promptly complete the processing for the resolved incident at each tollgate.

[0123] (7) In the seventh aspect, the tollgate device 2 installed at the tollgate includes a recording processing unit 201 that records the incident information D3 distributed from the monitoring device 1 on a recording medium 24 in the device, and an incident processing unit 205 that performs processing according to the incident information D3.

[0124] By doing so, the tollgate device 2 can automatically and promptly perform processing for the incident based on the incident information D3.

[0125] (8) In the eighth aspect, the incident processing unit 205 refers to a setting table T2 that associates incident type information with processing contents, and performs processing corresponding to the recorded incident type information included in the incident information D3.

[0126] By doing so, even when the incident information D3 does not include instruction information, the tollgate device 2 can automatically select and perform processing for the incident.

[0127] (9) In the ninth aspect, when the incident information D3 includes instruction information specifying the content of the processing to be performed, the incident processing unit 205 performs the processing specified by the instruction information.

[0128] By doing so, the tollgate device 2 only needs to execute the process specified by the incident information D3, so that the time until the execution of the process can be shortened. Also, depending on the incident, it may be necessary to finely change the instruction content for each tollgate. Even in such a case, the incident information D3 can include various instruction information for each tollgate based on the input operation of the supervisor. As a result, the tollgate device 2 can flexibly implement different responses for each tollgate.

[0129] (10) In the tenth aspect, the tollgate device 2 includes a vehicle information acquisition unit 202 that acquires vehicle identification information of a vehicle that has arrived at the tollgate, and a transmission unit 204 that transmits vehicle information D1 including the identification information of the tollgate and the vehicle identification information to the monitoring device 1.

[0130] By doing so, the tollgate device 2 can aggregate the vehicle information D1 regarding all vehicles passing through the tollgate to the monitoring device 1. Thereby, it becomes easy to monitor incidents related to vehicles, such as illegal vehicles, in the monitoring device 1. Also, when the tollgate device 2 can detect illegal passage with the sensor device at the tollgate, it may transmit vehicle information D1 including incident type information indicating the illegal passage to the monitoring device 1. Thereby, without the need for constant monitoring by the supervisor, an incident can be automatically detected at each tollgate and transmitted to the monitoring device 1.

[0131] (11) In the eleventh aspect, the tollgate device 2 includes a device abnormality detection unit 203 that detects the presence or absence of an abnormality in the devices installed at the tollgate, and when an abnormality in the device is detected, the transmission unit 204 transmits device information D2 including the identification information of the tollgate and information indicating the presence or absence of the device abnormality to the monitoring device 1.

[0132] By doing so, when an abnormality is detected in the tollgate equipment, the tollgate device 2 can promptly notify the monitoring device 1 of this. As a result, when support from other tollgates (for example, the processing at the exit tollgate G3 shown in FIG. 15) is required for the abnormality of this equipment, incident information D3 regarding this equipment abnormality can be shared among the tollgates that provide support, enabling appropriate countermeasures to be taken.

[0133] (12) In the twelfth aspect, the incident processing unit 205 executes processing when incident information D3 associated with the vehicle identification information acquired by the vehicle information acquisition unit 202 is recorded on the recording medium 24.

[0134] By doing so, when a vehicle related to an incident arrives at the tollgate, the tollgate device 2 can perform processing on the vehicle. For example, in the hot water shown in FIG. 13, when a vehicle that has made an illegal passage arrives at the exit tollgate, the tollgate device 2 can automatically and immediately perform various processes for vehicle control.

[0135] (13) In the thirteenth aspect, the monitoring system 9 includes the monitoring device 1 according to any one of the above aspects and the tollgate device 2 according to any one of the above aspects.

[0136] (14) In the fourteenth aspect, the monitoring method includes a step of creating incident information D3 including incident type information indicating the type of the incident when the incident is detected, and a step of distributing the incident information D3 to the tollgate device 2 of the tollgate that performs processing corresponding to the incident type information.

[0137] (15) In the fifteenth aspect, the program causes the computer of the monitoring device 1 to execute a step of creating incident information D3 including incident type information indicating the type of the incident when the incident is detected, and a step of distributing the incident information D3 to the tollgate device 2 of the tollgate that performs processing corresponding to the incident type information.
