[0012] <Embodiment 1> A first embodiment of the present invention will be described with reference to Figures 1 to 4. Figures 1 to 3 are diagrams for explaining the configuration of a vehicle status registration system, and Figure 4 is a diagram for explaining the processing operation of the vehicle status registration system.

[0013] [composition] The vehicle movement registration system of the present invention is a system for determining the current movement of emergency vehicles 2, such as ambulances and fire engines, that are dispatched in emergencies, and for registering and managing the movement in the command center 1. For example, the movement determined for the emergency vehicle 2 is "dispatched," "arrived," "dispatched," "transferred," "arrived at hospital," "withdrawn," "return to station," etc. if the emergency vehicle 2 is an ambulance, and "dispatched," "arrived," "started spraying water," "ended spraying water," "started rescue," "ended rescue," "withdrawn," "return to station," etc. if the emergency vehicle is a fire engine. However, the movement determined for the emergency vehicle 2 is not limited to those described above.

[0014] 1, the vehicle movement registration system includes an on-board device 20 mounted on an emergency vehicle 2 and a command center device 10 installed in a command center 1. The emergency vehicle 2 and the command center 1 are each equipped with wireless communication devices such as transceivers 28 and 18, and are configured to enable conversation between a person who will become an occupant 2A of the emergency vehicle 2 and a person such as a commander 1A employed at the command center 1 via the transceivers 28 and 18.

[0015] The in-vehicle device 20 is configured as an information processing device including a calculation device and a storage device. As shown in Fig. 2, the in-vehicle device 20 includes an AVM (Automatic Vehicle Monitoring) system 21 that is constructed by the calculation device executing a program. The in-vehicle device 20 also includes a vehicle information storage unit 22 formed in the storage device. As shown in Fig. 2, the in-vehicle device 20 is also connected to a communication device 27 that can transmit and receive data to and from the command center device 10 via wireless communication, a transceiver 28 that allows the occupant 2A to talk with outside persons, and a display device 26. Each component will be described in detail below.

[0016] The transceiver 28 is a communication device mounted on the emergency vehicle 2 and capable of communicating with an external person via wireless communication. In particular, the transceiver 28 mounted on the emergency vehicle 2 is configured to be capable of wireless connection with the transceiver 18 installed in the command center 1. This allows a conversation between the occupant 2A of the emergency vehicle 2 and the commander 1A of the command center 1 via the transceivers 28, 18.

[0017] The AVM system 21 transmits and receives data to and from the command center device 10 via the communication device 27, receives commands from the command center device 10, and transmits data necessary for registering the status of the emergency vehicle 2 itself to the command center device 10. For example, the AVM system 21 receives a command such as "dispatch" for the emergency vehicle 2 and displays the command on the display device 26 so that the occupant 2A can select it, or receives a command specifying the destination of the emergency vehicle 2 and displays destination information indicating the destination and the route together with map data on the display device 26. The AVM system 21 also receives the status of the emergency vehicle 2 determined by the command center device 10 and displays it on the display device 26. The AVM system 21 temporarily stores information such as commands and status transmitted from the command center device 10 in the vehicle information storage unit 22.

[0018] The AVM system 21 also acquires operating status information indicating the operating status of the emergency vehicle 2 detected by various sensors mounted on the emergency vehicle 2, and transmits the information to the command center device 10 via the communication device 27. For example, the AVM system 21 acquires, as the operating status information, the status of the engine of the emergency vehicle 2, i.e., whether the engine is running (ON state) or stopped (OFF state). The AVM system 21 also acquires, as the operating status information, the position information and traveling speed of the emergency vehicle 2. The AVM system 21 also acquires, as the operating status information, the traveling distance of the emergency vehicle 2, for example, the traveling distance from engine ON and the traveling distance from the starting point (such as a fire station). The AVM system 21 may temporarily store the operating status information acquired from the emergency vehicle 2 in the vehicle information storage unit 22 and then transmit the information to the command center device 10. In this case, the AVM system 21 may acquire and transmit the operating status information to the command center device 10 at a preset timing, for example, at regular time intervals, or may acquire and transmit the information at any timing.

[0019] However, the AVM system 21 is not necessarily limited to acquiring all of the above-mentioned information as the vehicle status information, but may acquire at least one of the above-mentioned information and transmit it to the command center device 10. Furthermore, the AVM system 21 may acquire information indicating an operating state of the emergency vehicle 2 different from the above-mentioned states as the vehicle status information and transmit it to the command center device 10. Note that the above-mentioned operating status information is not necessarily limited to being acquired by the AVM system 21, but may be acquired by another device mounted on the in-vehicle device 20 and transmitted to the command center device 10.

[0020] The transceiver 28 may be connected to the AVM system 21 and connected to the transceiver 18 of the command center 1 via the AVM system 21, or may not be connected to the AVM system 21 and may be connected to the transceiver 18 of the command center 1 without the AVM system 21. The transceivers 28, 18 may be configured as any other communication device capable of communicating between people. For example, the transceivers 28, 18 may be replaced with a mobile phone such as a smartphone that enables communication between people using a mobile phone network. When a mobile phone is installed instead of the transceivers 28, 18, the mobile phone may be connected to the AVM system 21, and the AVM system 21 may be configured to control calls, such as making and receiving calls.

[0021] The command center device 10 is composed of one or more information processing devices each including a calculation device and a storage device. As shown in FIG. 3, the command center device 10 includes a command unit 11, an acquisition unit 12, an analysis unit 13, and a determination unit 14. The functions of the command unit 11, the acquisition unit 12, the analysis unit 13, and the determination unit 14 can be realized by the calculation device executing a program for realizing each function stored in the storage device. The command center device 10 also includes a vehicle information storage unit 15. The vehicle information storage unit 15 is composed of a storage device.

[0022] 3, the command center device 10 includes a communication device 17 capable of transmitting and receiving data to and from the in-vehicle device 20 via wireless communication, a transceiver 18 that enables the commander 1A to communicate with the outside, and a display device 16. Each component will be described in detail below.

[0023] The transceiver 18 is a communication device that is grounded to the command center 1 and that is capable of communicating with an external person via wireless communication. In particular, the transceiver 18 mounted in the command center 1 is configured to be capable of wireless connection with the transceiver 28 installed in the emergency vehicle 2 as described above. This allows a conversation between the commander 1A of the command center 1 and the occupant 2A of the emergency vehicle 2 via the transceivers 18 and 28.

[0024] The command unit 11 transmits commands to the emergency vehicle 2 from the commander 1A at the command center 1 to the AVM system 21 via the communication device 17. For example, the command unit 11 transmits a command such as "dispatch" of the emergency vehicle 2 or a command indicating the destination of the emergency vehicle 2.

[0025] The acquisition unit 12 acquires conversation information between people via the transceiver 18 and temporarily stores it in a storage device. In particular, the acquisition unit 12 acquires conversation information between a commander 1A of the command center 1 and an occupant 2A of the emergency vehicle 2, which is being conducted between the commander 1A and the transceiver 28 of the emergency vehicle 2 connected to the transceiver 18 of the command center 1. The acquisition unit 12 may also acquire conversation information between the occupants 2A of the emergency vehicle 2, which is transmitted from the transceiver 28 of the emergency vehicle 2 and received by the transceiver 18 of the command center 1. Furthermore, if the transceivers 28, 18 are configured by mobile phones such as smartphones, the acquisition unit 12 may acquire conversation information between such mobile phones.

[0026] Furthermore, the acquisition unit 12 receives operation status information indicating the operation status of the emergency vehicle 2 transmitted from the emergency vehicle 2 via the communication device 17, and stores the information in the vehicle information storage unit 15. For example, the acquisition unit 12 acquires, as the vehicle status information, information such as the engine status of the emergency vehicle 2 (engine ON, OFF), the position of the emergency vehicle 2, the traveling speed of the emergency vehicle 2, and the distance traveled by the emergency vehicle 2 from a predetermined location. As another example, if the emergency vehicle 2 is a fire engine, the acquisition unit 12 may acquire a water discharge status (water discharge started, water discharge stopped) or the amount of water in the water tank of the fire engine. However, the acquisition unit 12 may acquire, as the operation status information, information indicating any vehicle operation status other than the above-mentioned information from the emergency vehicle 2.

[0027] Furthermore, the acquisition unit 12 acquires the current status of the emergency vehicle 2. For example, the acquisition unit 12 acquires information representing the current status of the emergency vehicle 2 stored in the vehicle information storage unit 15. However, the acquisition unit 12 may acquire information representing the current status of the emergency vehicle 2 from the emergency vehicle 2.

[0028] The analysis unit 13 performs a voice analysis of the acquired conversation information as described above and extracts predetermined keywords from the conversation information. For example, the analysis unit 13 may extract keywords consisting of the same characters as the above-mentioned movements, such as "dispatch," "arrival," and "dispatch," or may extract keywords consisting of other characters associated with these movements. The keywords extracted by the analysis unit 13 are used when the determination unit 14, which will be described later, determines the movement of the emergency vehicle 2, and are stored in a storage device together with movement determination criteria.

[0029] The analysis unit 13 may, for example, detect which person uttered the keyword extracted from the conversation information. For example, the analysis unit 13 may detect keywords from the conversation information uttered by the occupant 2A of the emergency vehicle 2 based on the input / output status of the conversation information in the transceiver 18, and extract only the keywords uttered by the occupant 2A. However, the analysis unit 13 may detect the person uttering the conversation information by any method. Furthermore, the analysis unit 13 does not necessarily need to detect the person who is speaking, and may extract keywords from the conversation information of all people.

[0030] Furthermore, the analysis unit 13 is not necessarily limited to extracting preset keywords from the conversation information, but may extract any information, such as extracting preset information from the conversation information. In this case, the analysis unit 13 extracts preset information to be used when determining the behavior in the determination unit 14, which will be described later.

[0031] The determination unit 14 determines a new movement of the emergency vehicle 2 based on the voice analysis results by the analysis unit 13, the vehicle status information acquired by the acquisition unit 12, and the current movement of the emergency vehicle 2. At this time, the determination unit 14 determines the new movement using all or part of the voice analysis results, the vehicle status information, and the current movement, based on the determination criteria for each movement stored in the storage device. Below are examples of each movement of the emergency vehicle 2 to be determined and the determination criteria for each movement.

[0034] The determination unit 14 stores and registers the movement of the emergency vehicle 2 determined based on the above-described determination criteria as a new movement in the vehicle information storage unit 15 together with the identification information of the emergency vehicle 2. The determination unit 14 also notifies the AVM system 21 of the emergency vehicle 2 of the determined movement.

[0035] The determination unit 14 determines the new status of the emergency vehicle 2 in accordance with the above-mentioned criteria for determining each status, but the new status may be determined based only on the voice analysis result, or based on the voice analysis result and vehicle state information, or based on the voice analysis result and the current status. In other words, the above-mentioned criteria for determining each status are merely examples, and any determination criteria may be set.

[0036] [Operation] Next, the operation of the vehicle movement registration system will be described, particularly the operation of the command center device 10 to determine and register the movement of the emergency vehicle 2, with reference to the flowchart in FIG.

[0037] First, assume that an occupant 2A is on board the emergency vehicle 2, and that the occupant 2A and a commander 1A of the command center 1 are conversing via the transceivers 28, 18. In this situation, the command center device 10 acquires conversation information input and output to the transceiver 18. That is, the command center device 10 acquires conversation information between the occupant 2A and the commander 1A, or conversation information between multiple occupants 2A. The command center device 10 also acquires vehicle status information of the emergency vehicle 2 transmitted from the in-vehicle device 20. Furthermore, the command center device 10 acquires the current movement of the emergency vehicle 2 that is stored (step S1).

[0038] The command center device 10 may always acquire the above-mentioned conversation information, vehicle status information, and current status and perform the analysis processing and status determination processing described below, or may acquire the conversation information, etc., and perform the following processing only when it detects conversation information input / output to / from the transceiver 18. Furthermore, if the transceivers 28, 18 or a mobile phone replacing them are connected to the AVM system 21 of the emergency vehicle 2 or the command center device 10, the command center device 10 may acquire the conversation information when a conversation is detected by the AVM system 21 or the command center device 10.

[0039] Next, the command center device 10 performs a voice analysis of the acquired conversation information and extracts preset keywords from the conversation information (step S2). Specifically, the command center device 10 extracts keywords set as criteria for determining the movement, as described below. For example, the command center device 10 extracts keywords consisting of the same characters as the movement information, such as "dispatch," "arrival," and "dispatch." At this time, the command center device 10 may detect keywords uttered by the occupant 2A of the emergency vehicle 2 based on the input / output status of the conversation information in the transceiver 18, particularly from only the conversation information output from the transceiver 18. However, the command center device 10 may extract keywords from conversation information from any person, and may perform a voice analysis to extract information used in determining the movement, not limited to keywords.

[0040] Thereafter, the command center device 10 determines a new movement of the emergency vehicle 2 based on the above-mentioned voice analysis result, the acquired vehicle status information, and the current movement of the emergency vehicle 2 (step S3). Specifically, the command center device 10 determines the new movement using all or part of the voice analysis result, vehicle status information, and current movement, based on the determination criteria for each movement set as described above. Note that the command center device 10 may determine the new movement based only on the voice analysis result, or may determine the new movement based on the voice analysis result and vehicle status information, or based on the voice analysis result and current movement, in accordance with the determination criteria for each movement.

[0041] The command center device 10 registers the status of the emergency vehicle 2 determined based on the above-mentioned determination criteria as a new status. The command center device 10 also notifies the AVM system 21 of the emergency vehicle 2 of the determined status.

[0042] As described above, in this embodiment, the conversation between the occupant 2A of the emergency vehicle 2, particularly the conversation between the occupant 2A and the commander 1A at the command center 1, is analyzed, and the current state of the emergency vehicle 2 is determined and registered based on the analysis results. This makes it possible to prevent the current state from not being registered because, for example, the occupant 2A forgets to operate the AVM system 21 to enter the current state of the emergency vehicle 2, thereby enabling more reliable registration of the current state of the emergency vehicle 2. By reliably registering the current state of the emergency vehicle 2 in this way, an appropriate response can be taken using the emergency vehicle 2 in an emergency situation.

[0043] Furthermore, in this embodiment, the new movement is determined not only by the conversation between the occupant 2A of the emergency vehicle 2, but also by reference to the vehicle condition and current movement of the emergency vehicle 2. This increases the accuracy of determining the movement of the emergency vehicle 2, and enables a more appropriate response to an emergency using the emergency vehicle 2.

[0044] Here, all or some of the functions of the command center device 10 described above, particularly the functions of the acquisition unit 12, the analysis unit 13, and the determination unit 14, may be provided in an information processing device other than the command center device 10. That is, the functions of the acquisition unit 12, the analysis unit 13, and the determination unit 14 may be provided in another information processing device, or may be distributed and provided in multiple information processing devices. For example, all of the functions of the acquisition unit 12, the analysis unit 13, and the determination unit 14 may be provided in the in-vehicle device 20, or some of the functions may be provided in the in-vehicle device 20 and the remaining some may be provided in the command center device 10, or in multiple information processing devices including the command center device 10.

[0045] <Embodiment 2> Next, a second embodiment of the present invention will be described with reference to Fig. 5 to Fig. 7. Fig. 5 to Fig. 6 are block diagrams showing the configuration of a vehicle status registration device in the second embodiment, and Fig. 7 is a flowchart showing the operation of the vehicle status registration device. Note that this embodiment shows an outline of the configuration of the command center device explained in the above embodiment.

[0046] First, the hardware configuration of the vehicle status registration device 100 in this embodiment will be described with reference to Fig. 5. The vehicle status registration device 100 is configured as a general information processing device, and is equipped with the following hardware configuration, as an example. ·CPU(Central Processing Unit)101(Arithmetic unit) ROM (Read Only Memory) 102 (storage device) RAM (Random Access Memory) 103 (storage device) Programs 104 loaded into RAM 103 A storage device 105 for storing a group of programs 104 A drive device 106 that reads and writes from a storage medium 110 external to the information processing device A communication interface 107 that connects to a communication network 111 outside the information processing device Input / output interface 108 for inputting and outputting data Bus 109 connecting each component

[0047] The vehicle movement registration device 100 can be equipped with an acquisition unit 121, an analysis unit 122, and a determination unit 123 shown in Fig. 6 by having the CPU 101 acquire and execute the group of programs 104. The group of programs 104 is stored in advance in the storage device 105 or the ROM 102, for example, and is loaded into the RAM 103 and executed by the CPU 101 as needed. The group of programs 104 may be supplied to the CPU 101 via the communication network 111, or may be stored in advance in the storage medium 110, and the drive device 106 may read out the programs and supply them to the CPU 101. However, the acquisition unit 121, the analysis unit 122, and the determination unit 123 may be constructed using dedicated electronic circuits for realizing such means.

[0048] 5 shows an example of the hardware configuration of the information processing device that is the vehicle movement registration device 100, and the hardware configuration of the information processing device is not limited to the above-described case. For example, the information processing device may be configured with only a part of the above-described configuration, such as excluding the drive device 106.

[0049] The vehicle status registration device 100 then executes the vehicle status registration method shown in the flowchart of FIG. 7 by the functions of the acquisition unit 121, analysis unit 122, and decision unit 123, which are constructed by the program as described above.

[0050] As shown in FIG. 7, the vehicle movement status registration device 100 Acquire conversation information between a plurality of people including at least one person who is an occupant of an emergency vehicle (step S101); The conversation information is subjected to a voice analysis (step S102). Based on the voice analysis result, the current state of the emergency vehicle is determined and registered (step S103). The following process is executed.

[0051] Here, the acquisition unit 121 acquires conversation information between multiple people, including at least one emergency vehicle occupant. That is, the acquisition unit 121 may acquire conversation information between an emergency vehicle occupant and an external person, such as a commander at a command center, or may acquire conversations between emergency vehicle occupants themselves. The analysis unit 122, for example, extracts pre-set keywords from the conversation information, but may perform any voice analysis process. The determination unit 123 then determines and registers the status of the emergency vehicle based on the results of the voice analysis of the conversation information, for example, the extracted keywords. For example, the status of the emergency vehicle may be "dispatched," "arrived," "started work," "completed work," "withdrawn," "returned," etc.

[0052] As described above, the present invention analyzes conversations between the occupants of an emergency vehicle, for example, conversations between the occupants and a dispatcher at a command center, and determines and registers the current status of the emergency vehicle based on the analysis results. This prevents the emergency vehicle from being registered due to, for example, the occupant forgetting to operate the AVM system to record the current status of the emergency vehicle, thereby enabling more reliable registration of the current status of the emergency vehicle. By reliably registering the current status of the emergency vehicle in this way, an appropriate response can be taken using the emergency vehicle in an emergency situation.

[0053] The above-described program can be stored and supplied to a computer using various types of non-transitory computer-readable media. Non-transitory computer-readable media include various types of tangible storage media. Examples of non-transitory computer-readable media include magnetic recording media (e.g., flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (e.g., magneto-optical disks), CD-ROMs (Read Only Memory), CD-Rs, CD-R / Ws, and semiconductor memories (e.g., mask ROMs, PROMs (Programmable ROMs), EPROMs (Erasable PROMs), flash ROMs, and RAMs (Random Access Memory)). The program may also be supplied to a computer by various types of transitory computer-readable media. Examples of transitory computer-readable media include electrical signals, optical signals, and electromagnetic waves.
