(First embodiment)
FIG. 1 is a diagram for explaining a use environment of the analysis apparatus 10 according to the first embodiment. The analysis device 10 is a device that detects the position of a puddle generated on a travel path (for example, a road) by analyzing sound data including travel sound generated when the mobile body 80 travels. The moving body 80 is a vehicle such as an automobile or a motorcycle. The audio data to be analyzed is generated by the audio data generation device 20 mounted on the moving body 80 and output to the analysis device 10. The analysis device 10 detects the puddle generated on the travel path by analyzing the audio data in real time. And when it detects that there is a puddle on the traveling road, the analysis device 10 uses the information for specifying the current position of the moving body 80 (hereinafter referred to as position specifying information) to specify the position of the puddle. Information is transmitted to the management device 30. The management device 30 stores the received position specifying information in the storage unit 40. The position specifying information is generated by, for example, a GPS information receiving device and a GPS information analyzing device mounted on the moving body 80, but may be generated using other methods.

  The analysis device 10 may store the audio data in a storage device mounted on the moving body 80 in association with the position specifying information. In this case, the analysis apparatus 10 performs a puddle detection process by batch processing. Specifically, the analysis device 10 reads audio data and position specifying information from the storage device. Then, the analysis device 10 transmits position specifying information corresponding to the sound data in which the puddle is detected to the management device 30. The storage device described above may be built in the analysis device 10.

  FIG. 2 is a diagram illustrating an example of a functional configuration of the analysis apparatus 10. The analysis apparatus 10 includes an acquisition unit 110 and a processing unit 120.

  The acquisition unit 110 acquires the above-described audio data and position specifying information. The acquisition unit 110 may acquire audio data from the audio data generation device 20, or may read audio data from a storage device mounted on the moving body 80. The position specifying information is generated by the GPS information analysis device as described above, for example. Here, the audio data and the position specifying information may be linked to each other using time information indicating the time at which they are generated.

  The processing unit 120 analyzes the sound data to determine whether there is a puddle at the point where the sound data is generated. An example of this process is a process for determining whether the sound data includes data indicating the running sound of the puddle. For example, when the feature data stored in advance is included in the voice data, the processing unit 120 determines that a puddle exists at the point where the voice data is generated.

  If the processing unit 120 determines that there is a puddle on the travel path, the processing unit 120 transmits position specifying information corresponding to the sound data to the management device 30.

  In addition, when the position specifying information acquired by the acquisition unit 110 indicates not only the position in the extending direction of the travel path but also the position in the width direction of the travel path or the lane, the position specifying information of the puddle is also the travel path or the lane. Both the position in the extending direction and the position in the width direction are shown.

  FIG. 3 is a diagram illustrating an example of a hardware configuration of the analysis apparatus 10. The main configuration of the analysis apparatus 10 is realized using an integrated circuit. This integrated circuit includes a bus 402, a processor 404, a memory 406, a storage device 408, an input / output interface 410, and a network interface 412. The bus 402 is a data transmission path through which the processor 404, the memory 406, the storage device 408, the input / output interface 410, and the network interface 412 transmit / receive data to / from each other. However, the method of connecting the processors 404 and the like is not limited to bus connection. The processor 404 is an arithmetic processing unit realized using a microprocessor or the like. The memory 406 is a memory realized using a RAM (Random Access Memory) or the like. The storage device 408 is a storage device realized using a ROM (Read Only Memory), a flash memory, or the like.

  The input / output interface 410 is an interface for connecting the analysis apparatus 10 to a peripheral device. In the figure, an input / output interface 410 is an example of the acquisition unit 110. Therefore, the audio data generation device 20 and a device that generates position data are connected to the input / output interface 410. The input / output interface 410 is connected to an external storage device as necessary.

  The network interface 412 is an interface for connecting the analysis apparatus 10 to a communication network. This communication network is, for example, a CAN (Controller Area Network) communication network and a communication network outside the mobile unit 80. Note that a method of connecting the network interface 412 to the communication network may be a wireless connection or a wired connection.

  The storage device 408 stores program modules for realizing each functional element of the analysis apparatus 10. The processor 404 implements each function of the analysis apparatus 10 by reading this program module into the memory 406 and executing it.

  Note that the hardware configuration of the integrated circuit described above is not limited to the configuration shown in FIG. For example, the program module may be stored in the memory 406. In this case, the integrated circuit may not include the storage device 408.

  Also, the hardware configuration of the management apparatus 30 is the same as the hardware configuration of the analysis apparatus 10 shown in FIG.

  As described above, according to the present embodiment, the analysis device 10 detects the location of the puddle, and transmits the position specifying information to the management device 30 in order to specify the detected location. The management device 30 stores the received position specifying information in the storage unit 40. For this reason, by analyzing the information stored in the storage unit 40, it is possible to detect a place where a puddle is likely to be generated, that is, a place where there is a high possibility of deterioration.

  In addition to the depressions that can be detected with the naked eye, the places that can be detected in the present embodiment include depressions that are gently depressed and difficult to see with the naked eye. Further, it is possible to detect a place where water permeability is deteriorated due to clogging among places having a water-permeable pavement material.

(Second Embodiment)
FIG. 4 is a diagram illustrating a functional configuration of the analysis apparatus 10 according to the second embodiment. The analysis apparatus 10 according to the present embodiment has the same configuration as the analysis apparatus 10 according to the first embodiment, except that weather information is used.

  Specifically, the acquisition unit 110 acquires weather information in association with voice data and position specifying information. The weather information indicates the weather at the position indicated by the position specifying information when the sound data is generated. The weather information may be acquired from the outside of the moving body 80, for example, via a communication line, or an apparatus mounted on the moving body 80, for example, an imaging apparatus that images the surroundings of the moving body 80 and the imaging apparatus generates the weather information. The image may be generated by an image processing apparatus that processes the processed image. The weather information may be input to the analysis device 10 by a person who is on the moving body 80.

  And the process part 120 judges whether the detection process of a puddle is performed using weather information. For example, the processing unit 120 performs a puddle detection process when the weather information indicates rainfall and the amount of rainfall within the reference time satisfies the criterion. The reference time is, for example, within 1 hour, within 3 hours, or within 6 hours, but is not limited thereto. Moreover, it is preferable that both the upper limit and the lower limit are defined in the standard of precipitation. The reason for setting the upper limit is that if there is too much precipitation, almost the entire road may be flooded. The reason why the lower limit is determined is that there is a high possibility that no puddle is generated when the precipitation is too small (or 0).

  In addition, when the analysis apparatus 10 performs a puddle detection process by batch processing, the acquisition unit 110 may read out only the sound data and the position specifying information whose weather information satisfies the standard.

  As described above, according to the present embodiment, the analysis device 10 detects the location of the puddle, and transmits the position specifying information to the management device 30 in order to specify the detected location, as in the first embodiment. For this reason, by analyzing the information stored in the storage unit 40, it is possible to detect a place where a puddle is likely to be generated, that is, a place where there is a high possibility of deterioration.

  The processing unit 120 performs the puddle detection process only when there is a high possibility that the puddle is moderately generated. For this reason, the amount of calculation performed by the processing unit 120 is reduced.

(Third embodiment)
FIG. 5 is a diagram illustrating a configuration of the analysis apparatus 10 according to the third embodiment. The analysis apparatus 10 according to the present embodiment has the same configuration as the analysis apparatus 10 according to the first or second embodiment, except that the path setting unit 130 and the output unit 140 are provided. FIG. 5 shows the same case as in the second embodiment.

  The route setting unit 130 uses the position specifying information stored in the storage unit 40 shown in FIG. 1, that is, information for specifying the position of the puddle, to indicate information indicating the moving route of the moving body 80 (hereinafter referred to as a route). Information and description). For example, the route setting unit 130 acquires information indicating the destination (hereinafter referred to as destination information) and information indicating the current position of the mobile unit 80 (hereinafter referred to as current position information). The destination information is input by a passenger of the moving body 80, for example. The current position information is generated by a device that generates the above-described position specifying information. Information for specifying the position of the puddle is read from the storage unit 40. Then, the route setting unit 130 sets the movement route on the condition that the number or length of the puddles passing therethrough is equal to or less than the reference value. The route setting unit 130 may set a movement route using still other conditions.

  The output unit 140 outputs the route information for controlling the moving body 80. For example, the output unit 140 outputs route information to the navigation device. In this case, the navigation device displays the route indicated by the route information on the display.

  When the position information of the puddle also indicates the position in the width direction of the travel path or lane, the path information includes the width that the moving body 80 should pass at each point included in the path in addition to the travel path itself. The position in the direction may be specified.

  As described above, according to the present embodiment, the analysis device 10 detects the location of the puddle, and transmits the position specifying information to the management device 30 in order to specify the detected location, as in the first embodiment. For this reason, by analyzing the information stored in the storage unit 40, it is possible to detect a place where a puddle is likely to be generated, that is, a place where there is a high possibility of deterioration.

  Furthermore, the route setting unit 130 of the analysis apparatus 10 sets the moving route of the moving body 80 so as to avoid a degraded place in the traveling route. For this reason, it is possible to suppress deterioration of a specific place in the traveling path, and it is possible to suppress the ride comfort of the moving body 80 when moving to the destination.

(Fourth embodiment)
FIG. 6 is a diagram for explaining a use environment of the analysis apparatus 10 according to the fourth embodiment. In the present embodiment, the analysis device 10 is disposed outside the moving body 80 and communicates with the communication device 50 and the control device 60 mounted on the moving body 80. The acquisition unit 110 of the analysis device 10 acquires information necessary for specifying the position of the puddle, such as voice data and position specifying information, from the communication device 50. Then, the analysis device 10 causes the storage unit 40 to store position specifying information for specifying the position of the puddle. The processing performed by the analysis apparatus 10 is the same as that in the first embodiment or the second embodiment.

  In the present embodiment, the communication device 50 may transmit only the sound data and the position specifying information that meet the criteria of the weather information to the analysis device 10. In other words, the communication device 50 transmits voice data to the analysis device 10 when the weather during traveling satisfies the criteria.

  Further, the control device 60 of the moving body 80 includes the route setting unit 130 and the output unit 140 described in the third embodiment. The processing performed by the route setting unit 130 and the output unit 140 is as described in the third embodiment. Furthermore, the control device 60 controls the movement of the moving body 80 so as to follow the movement route set by the route setting unit 130.

  Also in this embodiment, the analysis apparatus 10 may include the path setting unit 130 and the output unit 140. In this case, the analysis device 10 outputs route information to the control device 60.

  Also according to the present embodiment, the analysis apparatus 10 detects the location of the puddle and stores the position specifying information for specifying the detected location in the storage unit 40, as in the first embodiment. For this reason, by analyzing the information stored in the storage unit 40, it is possible to detect a place where a puddle is likely to be generated, that is, a place where there is a high possibility of deterioration.

  Further, since the analysis device 10 is located outside the moving body 80, it is possible to suppress the analysis device 10 from being deteriorated due to vibration or the like. Moreover, since it is sufficient to prepare one analysis device 10 for a plurality of moving bodies 80, the cost of the entire system can be reduced.

  As mentioned above, although embodiment and the Example were described with reference to drawings, these are illustrations of this invention and can also employ | adopt various structures other than the above.
