Summary of the Invention

Problems to be Solved by the Invention

[0004] When it is desired to successively measure the remaining grooves as the state of the tire without detaining vehicles that continuously enter, the remaining groove data of the first axis and the remaining groove data of the second axis measured within a predetermined time are associated as the remaining groove data of one vehicle. For example, when only the remaining groove data of the first axis is measured within a predetermined time, it is conceivable to discard and reset the remaining groove data of the first axis.

[0005] Here, for example, after the front wheels of a vehicle pass through the remaining groove measuring device and then the vehicle backs for some reason and the front wheels pass through the remaining groove measuring device again. In this case, it is erroneously recognized that the rear wheels have passed when the front wheels pass through the remaining groove measuring device again.

[0006] Also, assume that after the front wheel passes through the remaining groove measuring device, the rear wheel does not pass through the remaining groove measuring device for a predetermined time or more, and then the rear wheel passes through the remaining groove measuring device. In this case, since the remaining groove data of the front wheel is discarded and reset when the predetermined time has elapsed, the subsequent front wheel of the vehicle may misrecognize that the rear wheel has passed through the remaining groove measuring device as its own front wheel has passed through.

[0007] The present disclosure has been made in view of the above points, and an object thereof is to provide an information processing apparatus, an information processing method, and an information processing program that can prevent the association between tire state data indicating the state of a vehicle's tire and the vehicle from being misaligned.

[0014] The information processing apparatus according to the seventh aspect is the information processing apparatus according to the second aspect, wherein the output unit outputs the measurement result of the remaining groove of the tire as a risk level in a plurality of stages.

[0015] The information processing apparatus according to the eighth aspect is the information processing apparatus according to any one of the first to seventh aspects, wherein when the vehicle approach data is acquired before all of the measurement results of the plurality of axes are acquired, the association unit does not associate the tire state data of the plurality of axes with the vehicle approach data.

[0016] The information processing method according to the ninth aspect includes a process in which a computer acquires tire state data including a measurement result of the state of a tire of a vehicle measured by a measurement device that measures the state of the tire and a measurement date and time when the state of the tire was measured, acquires vehicle approach data including an approach date and time when the vehicle approached the measurement device, associates the tire state data of a plurality of axes with the vehicle approach data for each vehicle, and outputs information regarding the tire state data of the target vehicle.

[0017] The information processing program according to the tenth aspect causes a computer to acquire tire state data including a measurement result of measuring the state of a tire of a vehicle from a measuring device that measures the state of the tire and a measurement date and time when the state of the tire was measured, acquire vehicle approach data including an approach date and time when the vehicle approached the measuring device, associate the tire state data of a plurality of axes with the vehicle approach data for each vehicle, and output information regarding the tire state data of the target vehicle, and execute a process including this.

Mode for Carrying Out the Invention

[0020] Hereinafter, an example of an embodiment of the present disclosure will be described with reference to the drawings. In each drawing, the same or equivalent components and parts are given the same reference numerals. Also, the dimensional ratios in the drawings are exaggerated for the convenience of explanation and may be different from the actual ratios.

[0021] <First Embodiment>

[0022] FIG. 1 is an explanatory diagram showing the overall configuration of the vehicle state notification system 100 according to the present embodiment. FIG. 2 is a diagram showing the schematic configuration of the vehicle state notification system 100 according to the present embodiment. Hereinafter, the configuration of the vehicle state notification system 100 will be described with reference to FIGS. 1 and 2.

[0023] In FIG. 1, the configuration of the entrance of the parking lot 111 is described using schematic diagrams of each device. Note that the shape and size ratio of each device are not limited to the example of FIG. 1. Also, in the present embodiment, the case where each device is installed at the entrance of the parking lot 111 will be described as an example, but each device may be installed, for example, at a drive-through of a restaurant.

[0024] At the entrance of the parking lot 111, along the traveling road 109, a gutter measuring device 20, a camera 102, a ticket issuing machine 30, a parking ticket issuing machine 104, and an entrance gate 105 are installed. Also, at least above the ticket issuing machine 30 and the parking ticket issuing machine 104, a roof 106 is installed to prevent the paper surface issued by the ticket issuing machine 30 or the parking ticket issuing machine 104 from getting wet by rain, and to prevent the passengers of the vehicle receiving the paper surface from getting wet.

[0025] The ticket issuing machine 30 of the present embodiment includes an information processing device 10. The vehicle state notification system 100 of the present embodiment includes an information processing device 10, a gutter measuring device 20, a ticket issuing machine 30, and a server 40 (see FIG. 2).

[0026] The remaining groove measuring device 20 is a device for measuring the depth of the remaining groove of a tire. The remaining groove measuring device 20 is an example of a measuring device. The vehicle enters the area from the road 101 to the parking lot 111 and first passes through the remaining groove measuring device 20 which is a measuring device. The remaining groove measuring device 20 of the present embodiment is an elevating type with a slight inclination, and the depth of the remaining groove of the tire can be measured just by the vehicle passing slowly without stopping for a long time. Note that the remaining groove measuring device 20 may be embedded in the road surface. The measurement result of the remaining groove of the tire measured by the remaining groove measuring device 20 is transmitted to the information processing device 10.

[0027] The camera 102 is a photographing device for photographing the vehicle. The camera 102 photographs the license plate of the vehicle that has passed through the remaining groove measuring device 20. The image of the license plate is transmitted to the information processing device 10. Note that the vehicle may be photographed as a moving image, the license plate part may be recognized by image analysis and extracted as a still image, and the vehicle number may be obtained as character information by OCR (Optical Character Recognition) processing and transmitted to the information processing device 10. In this case, the vehicle approaching date and time described later may be the date and time when the license plate part is recognized by image analysis and extracted as a still image.

[0028] The ticket issuing machine 30 is a device for issuing a two-dimensional code. The ticket issuing machine 30 is an example of an operating device. This ticket issuing machine 30 is provided with a display 113, buttons 30B, and a printer (not shown) on the side facing the vehicle. Note that the code to be issued is not limited to a two-dimensional code and may also be a one-dimensional code. Hereinafter, the two-dimensional code will be described as an example.

[0029] On the display 113, character information provided to the vehicle occupants is displayed. In this embodiment, the character information to be provided is, for example, a message asking for the necessity of providing the measurement result of the remaining groove of the vehicle's tire (hereinafter sometimes simply referred to as "measurement result") to the vehicle occupants, such as "Do you want to check the remaining groove of the tire?". The button 30B is a push-type switch. The button 30B is pressed when a vehicle occupant, who is a user, wants to know the measurement result of the remaining groove. The printer is a printing device for printing a two-dimensional code.

[0030] When a vehicle occupant presses the button 30B as an intention that the provision of the measurement result is necessary, the printer prints a two-dimensional code on a piece of paper and outputs the piece of paper with the two-dimensional code printed thereon. On the contrary, when a vehicle occupant does not press the button 30B as an intention that the provision of the measurement result is unnecessary, the printer does not print a two-dimensional code on the paper and does not output the paper, that is, does not perform printing. The two-dimensional code 103 is printed and issued on a piece of paper as in the example of FIG. 1. The vehicle occupant can take home the piece of paper with the two-dimensional code 103 printed thereon and confirm the measurement result by reading the two-dimensional code with a communication terminal such as a smartphone. Note that the two-dimensional code 103 is a unique code for each vehicle and each passing time.

[0031] The information processing device 10 included in the ticket issuing machine 30 is a computer that performs a notification process of the vehicle state. The information processing device 10 of this embodiment executes a notification process of the remaining groove of the tire as the vehicle state. The information processing device 10 acquires an image of the license plate and the measurement result. In addition, the information processing device 10 acquires the pressing information of the button 30B of the ticket issuing machine 30, in other words, information related to the intention of whether to provide the measurement result of the remaining groove in the tire to the vehicle occupants. The information processing device 10 stores the measurement result of the remaining groove of the tire for each vehicle. Note that instead of the license plate of the vehicle, the camera 102 may capture the overall appearance of the vehicle, associate the appearance image of the vehicle with the measurement result, and store it in the information processing device 10.

[0032] The parking ticket issuing machine 104 is a device that issues parking tickets. When the vehicle reaches the parking ticket issuing machine 104 after passing through the ticket issuing machine 30, a parking ticket is issued to the passenger. Note that the parking ticket issuing machine 104 and the ticket issuing machine 30 may be configured as one device. When the passenger obtains the parking ticket, the entrance gate 105 that closes the entrance of the parking lot 111 opens. When the entrance gate 105 opens, the vehicle can enter the parking lot 111.

[0033] As shown in FIG. 2, the information processing device 10 and the remaining groove measuring device 20 are configured to be able to communicate with each other by wired communication or wireless communication. Also, the information processing device 10 and the ticket issuing machine 30 are configured to be able to communicate with each other by wired communication or wireless communication. Furthermore, the information processing device 10 and the server 40 are connected via the network N and are configured to be able to communicate with each other. The network N is exemplified by a public communication network such as 4G or 5G.

[0034] As described above, the information processing device 10 of the present embodiment holds the measurement result data received from the remaining groove measuring device 20. The information processing device 10 transmits the measurement result data to the server 40 at a predetermined timing.

[0035] The server 40 is a server existing in a cloud environment. The server 40 receives the measurement result from the information processing device 10. The measurement result is stored in the storage of the server 40.

[0036] FIG. 3 shows the hardware configuration of the information processing device 10. As shown in FIG. 3, the information processing device 10 includes a controller 11.

[0037] As shown in FIG. 3, the controller 11 includes a CPU (Central Processing Unit) 11A, a ROM (Read Only Memory) 11B, a RAM (Random Access Memory) 11C, and an input / output interface (I / O) 11D. The CPU 11A, the ROM 11B, the RAM 11C, and the I / O 11D are respectively connected via a bus 11E. The bus 11E includes a control bus, an address bus, and a data bus.

[0038] Further, a communication unit 12 and a storage unit 13 are connected to the I / O 11D.

[0039] The communication unit 12 is an interface for communicating with the remaining groove measuring device 20, the ticket issuing machine 30, the server 40, etc.

[0040] The storage unit 13 is composed of, for example, a non-volatile semiconductor memory, etc. As shown in FIG. 3, the storage unit 13 stores an information processing program 13A, tire state data 13B, vehicle approach data 13C, association data 13D, etc.

[0041] The CPU 11A is an example of a computer. The computer mentioned here refers to a processor in a broad sense and includes a general-purpose processor (e.g., CPU) or a dedicated processor (e.g., GPU: Graphics Processing Unit, ASIC: Application Specific Integrated Circuit, FPGA: Field Programmable Gate Array, programmable logic device, etc.).

[0042] Note that the information processing program 13A may be stored in a non-volatile non-transitory recording medium, distributed via a network, and appropriately installed in the information processing apparatus 10 to be stored in the storage unit 13.

[0043] Examples of non-volatile non-transitory recording media include CD-ROM (Compact Disc Read Only Memory), magneto-optical disks, HDDs (hard disk drives), DVD-ROMs (Digital Versatile Disc Read Only Memory), flash memories, memory cards, and the like.

[0044] Next, with reference to FIG. 4, the functional configuration of the information processing apparatus 10 according to the present embodiment will be described. As shown in FIG. 4, the information processing apparatus 10 of the present embodiment functions as a first acquisition unit 14, a second acquisition unit 15, an association unit 16, and an output unit 17 by the CPU 11A executing an information processing program 13A stored in the storage unit 13.

[0045] The first acquisition unit 14 acquires tire state data 13B including a measurement result of measuring a tire remaining groove as an example of a tire state and a measurement date and time of measuring the tire remaining groove from a remaining groove measuring device 20 as an example of a device for measuring the state of a vehicle tire.

[0046] Also, the first acquisition unit 14 acquires, for example, tire state data 13B of at least the front and rear tires.

[0047] The second acquisition unit 15 acquires vehicle approach data 13C including the vehicle approach date and time when the vehicle approaches the remaining groove measuring device 20. Also, the second acquisition unit 15 acquires a captured image of the vehicle taken by the camera 102, acquires the vehicle number from the acquired captured image, and includes it in the vehicle approach data 13C. The vehicle number can be acquired from the captured image using a known image analysis method.

[0048] Therefore, the approach date and time when the vehicle approaches the remaining groove measuring device 20 can be, for example, the date and time when the vehicle number is acquired.

[0049] The association unit 16 associates, for each vehicle, the tire state data 13B of multiple axes, for example, the tire state data 13B of the front wheels and the rear wheels, with the vehicle approach data 13C, and generates association data 13D. Specifically, the association unit 16 associates the tire state data 13B for each vehicle based on the tire state data 13B of multiple axes and the vehicle approach data 13C acquired within a predetermined period.

[0050] For example, as shown in FIG. 5, when the measurement date and time t2 at which the remaining groove of the first axis was measured and the measurement date and time t3 at which the remaining groove of the second axis was measured by the remaining groove measuring device 20 are included within a predetermined period D from the vehicle approach date and time t1 which is the date and time when the number of the vehicle 50 was acquired, the remaining groove data of the first axis is used as the remaining groove data of the front wheel 50F, and the remaining groove data of the second axis is used as the remaining groove data of the rear wheel 50R, and they are associated with the number of the vehicle acquired at the vehicle approach date and time t1. Note that the period D may be, for example, several minutes, but is not limited thereto.

[0051] Also, for example, as shown in FIG. 6, when the measurement date and time t2 at which the remaining groove of the first axis was measured and the measurement date and time t3 at which the remaining groove of the second axis was measured are included within a predetermined period D before and after the vehicle approach date and time t1, the remaining groove of the first axis may be used as the remaining groove of the front wheel 50F, and the remaining groove of the second axis may be used as the remaining groove of the rear wheel 50R, and they may be associated with the number of the vehicle acquired at the vehicle approach date and time t1. Also, the remaining groove data measured at the measurement date and time t4 outside the predetermined period D may be discarded.

[0052] Also, when the vehicle approach date and time is acquired before all the measurement results of multiple axes, for example, the measurement results of the front wheels and the rear wheels are acquired, the association unit 16 does not associate the tire state data 13B of multiple axes with the vehicle approach data 13C. For example, this is a case where the front wheel 50F of the vehicle 50 has passed through the remaining groove measuring device 20 and the remaining groove data of the front wheel 50F can be acquired, but the rear wheel 50R has come off the wheel and the remaining groove data cannot be acquired, and the vehicle approach date and time of the subsequent vehicle has been acquired.

[0053] FIG. 7 shows a specific example of the tire state data 13B and the vehicle approach data 13C. Also, FIG. 8 shows a specific example of the association data 13D.

[0054] As shown in FIG. 7, assume that the number of the vehicle 50 is acquired at time t1, the remaining groove data of the right and left wheels of the first axis is measured at time t2, and the remaining groove data of the right and left wheels of the second axis is measured at time t3. In this case, when time t3 is within a predetermined period D from time t1, as shown in FIG. 8, vehicle approach data including the number of the vehicle acquired at time t1 and the vehicle approach date and time, and tire state data 13B including the remaining groove data and the measurement date and time acquired at times t2 and t3 are associated to generate association data 13D. Note that the association data 13D is, for example, periodically transmitted to the server 40 and managed by the server 40.

[0055] Also, as shown in FIG. 7, assume that the number of the vehicle 50 is acquired at time t4, the remaining groove data of the first axis is measured at time t5, and then, for some reason such as wheel detachment, the remaining groove data of the second axis is not measured, and the number of the subsequent vehicle 50 is acquired at time t6. In this case, since the remaining groove data of the front and rear wheels could not be acquired as a set, the vehicle approach data 13C acquired at time t4 and the tire state data 13B acquired at time t5 are discarded.

[0056] Also, as shown in FIG. 7, assume that the number of the vehicle 50 is acquired at time t6, the remaining groove data of the first axis is measured at time t7, the remaining groove data of the second axis is measured at time t8, and the remaining groove data of the third axis is measured at time t9. In this case, when a vehicle having double tires or a special vehicle with three or more axes is not assumed, the vehicle approach data 13C acquired at time t6 and the tire state data 13B acquired at times t7 to t9 may be discarded.

[0057] The output unit 17 outputs, as information regarding the tire state data of the target vehicle, for example, a two-dimensional code. The vehicle 50 that has passed through the remaining groove measuring device 20 proceeds to the ticket issuing machine 30. Here, a message for requesting a display of the necessity of providing the measurement result of the remaining groove of the tire is displayed on the display 113 of the ticket issuing machine 30. When the passenger presses the button 30B, a two-dimensional code is printed by a printer (not shown). The two-dimensional code is information for accessing the remaining groove data measured by the remaining groove measuring device 20, specifically, the association data 13D managed by the server 40, and includes, for example, information on the vehicle approach date and time and the vehicle number. The passenger accesses the server 40 by reading the printed two-dimensional code with a communication terminal such as a smartphone, and checks the measurement result of the remaining groove corresponding to the vehicle number indicated by the two-dimensional code.

[0058] Further, the output unit 17 may output the measurement result of the remaining groove of the tire as multiple levels of risk.

[0059] FIG. 9 shows an example of displaying the measurement result on the screen of a Web application in a form that can be confirmed by the passenger. The screen of the measurement result is displayed on the communication terminal by reading the two-dimensional code issued by the ticket issuing machine 30 with a communication terminal such as a smartphone. Note that the code is a unique code for each user, and more specifically, for each passing time, and a unique Web page may be created for each code. Further, when the user accesses a common Web page and enters the vehicle number without the ticket issuing machine 30 issuing a two-dimensional code, the measurement result corresponding to the entered number may be displayed on the screen of the Web application. Further, a two-dimensional code reading device may be provided at the position of the ticket issuing machine 30, and the user may first log in to the Web application to obtain a two-dimensional code dedicated to himself / herself, and the remaining groove measurement may be accepted by having the two-dimensional code read by the reading device.

[0060] Each item shown in FIG. 9 will be described. Note that each item displayed on the screen shown in FIG. 9 is an example and is not limited thereto. Also, the layout and design are not limited to the example of FIG. 9.

[0061] Message 121 describes the measurement results of the remaining groove in text and then presents the actions to be taken by the occupant.

[0062] The four - stage gauge 122 visually shows the wear state of the tire, that is, the remaining groove of the tire, in a color - coded four - stage display. Specifically, as shown in Figure 9, A of the four - stage gauge 122 is blue, B is green, C is yellow, and D is red. A of the four - stage gauge 122 indicates that the tire is as good as new, B indicates that the tire has a little usage, C indicates that the tire replacement time is approaching soon, and D indicates that it is time to replace the tire. That is, the measurement results of the remaining groove of the tire are displayed as the risk levels of multiple stages.

[0063] When the warning color D's red color is shown, the occupant can notice that it is time to replace the tire. In the example of Figure 9, since the remaining groove of the right front tire is small, the message 121 recommending replacement is displayed.

[0064] The depth 123 numerically shows the actual depth of the remaining groove of the tire. The depth 123 displays the depth of the remaining groove for each of the four tires. Also, regarding the measurement results, the measurement results of all grooves may be output, or the average value of the depths of all grooves or the depth of the shallowest groove may be output.

[0065] The number 124 is the vehicle - specific number obtained by image analysis from the photographed image taken by the camera 102.

[0066] As shown in the screen of Figure 9, the measurement results of the remaining groove of the vehicle associated with the number 124 are displayed. Also, since the associated data 13D includes past measurement results, based on the past measurement results, the transition of the remaining groove of the tire can be calculated, and the tire replacement time can be predicted.

[0067] Tire type 125 is an item that allows the vehicle occupant to select whether the vehicle's tires are summer tires or winter tires (e.g., studless tires). Since the remaining groove threshold of the tire to be replaced varies depending on the tire type, a value of the same depth 123 may or may not correspond to the item to be replaced. Also, the content of the message 121 varies depending on the tire type.

[0068] Next, the operation of the information processing apparatus 10 according to the present embodiment will be described. FIG. 10 is a flowchart showing the flow of information processing executed by the CPU 11A of the information processing apparatus 10. Note that the information processing shown in FIG. 10 is repeatedly executed.

[0069] In step S100, the CPU 11A acquires a captured image from the camera 102 and acquires the number of the vehicle 50 by image analysis.

[0070] In step S101, the CPU 11A determines whether the number acquired in step S100 is a new number different from the number acquired last time. If the acquired number is a new number, the process proceeds to step S102. If the acquired number is not a new number and is the same as the number acquired last time, this routine ends.

[0071] In step S102, it is determined whether the remaining groove data for the first axis and the second axis has been acquired within a predetermined period D from the date and time when the number was acquired in step S100, that is, the vehicle approach date and time. If the remaining groove data for the first axis and the second axis has been acquired within the predetermined period D from the vehicle approach date and time, the process proceeds to step S103. On the other hand, if the remaining groove data for the first axis and the second axis has not been acquired within the predetermined period D from the vehicle approach date and time, for example, if only the remaining groove data for the first axis could be acquired within the predetermined period D, the process proceeds to step S104.

[0072] In step S103, the CPU 11A generates association data 13D by associating vehicle approach data 13C including the vehicle number and the vehicle approach date and time acquired in step S100 with tire state data 13B including the remaining groove data of the first axis, the remaining groove data of the second axis, and the measurement date and time acquired in step S102, and stores the association data 13D in the storage unit 13.

[0073] In step S104, the CPU 11A performs a reset process. That is, for example, when only the remaining groove data of the first axis could be acquired in step S102, the remaining groove data of the first axis and the number data acquired in step S100 are discarded. That is, the process of associating the vehicle approach data 13C and the tire state data 13B is not performed.

[0074] As described above, in the present embodiment, the vehicle number is acquired, and the vehicle state data including the remaining groove data of the first axis and the second axis acquired later is associated with the vehicle approach data including the number. Thereby, it is possible to prevent the association between the remaining groove data and the vehicle from being shifted as compared with the case where the vehicle number is not acquired.

[0075] <Second Embodiment>

[0076] Next, the second embodiment will be described. The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed descriptions thereof are omitted.

[0077] In the second embodiment, a case where a detection sensor for detecting the passage of the vehicle 50 is provided instead of the camera 102 will be described.

[0078] As the detection sensor, for example, as shown in FIG. 11, a photoelectric sensor 60 including a light projecting unit 60A and a light receiving unit 60B can be used. The light projecting unit 60A is attached to a support column 62A. The light receiving unit 60B is attached to a support column 62B.

[0079] The photoelectric sensor 60 is installed, for example, near the remaining groove measuring device 20 and, for example, near the height of the bumper of the vehicle 50.

[0080] When the vehicle 50 is not passing between the light projecting unit 60A and the light receiving unit 60B, the light L projected from the light projecting unit 60A is received by the light receiving unit 60B. Therefore, it can be determined that the vehicle 50 is not passing during the period when the light receiving unit 60B receives the light L. On the other hand, when the vehicle 50 is passing between the light projecting unit 60A and the light receiving unit 60B, the light L projected from the light projecting unit 60A is blocked by the vehicle 50 and not received by the light receiving unit 60B. Therefore, it can be determined that the vehicle 50 is passing during the period when the light receiving unit 60B does not receive the light L.

[0081] In the second embodiment, the second acquisition unit 15 acquires the passing start date and time of the vehicle 50 from the detection result of the photoelectric sensor 60, which is an example of a detection sensor for detecting the passing of the vehicle 50, and includes it in the vehicle approach data 13C. That is, the date and time when the light L is no longer detected from the state where the light L is detected by the light receiving unit 60B is included in the vehicle approach data 13C as the passing start date and time of the vehicle 50. Note that the passing start date and time corresponds to the vehicle approach date and time in the first embodiment.

[0082] Next, the operation of the information processing apparatus 10 according to the present embodiment will be described. FIG. 12 is a flowchart showing the flow of information processing executed by the CPU 11A of the information processing apparatus 10. Note that the information processing shown in FIG. 12 is repeatedly executed.

[0083] In step S101A, the CPU 11A determines whether the vehicle 50 has started passing. That is, it is determined whether the state has changed from the state where the light L is detected by the photoelectric sensor 60 to the state where the light L is not detected. If it is determined that the vehicle 50 has started passing, the process proceeds to step S102. If it is determined that the vehicle 50 has not started passing, this routine ends.

[0084] The processing in steps S102 to S104 is the same as that in the first embodiment, and the "vehicle approach date and time" in the first embodiment may be read as the "passing start date and time".

[0085] Note that the configuration, operation, etc. of the vehicle state notification system 100 described in the above embodiments are merely examples, and it goes without saying that they can be changed according to the situation without departing from the gist of the present disclosure.

[0086] For example, the method of displaying the measurement results to the passengers is not limited to the method of displaying them on the communication terminals of the passengers through a web application. For example, it may be performed on the display 113 of the ticket vending machine 30. Also, the display of the measurement results may be performed on the display of the digital signage installed at the exit of the parking lot 111. Further, a paper sheet on which the content of the measurement results is described may be output from the ticket vending machine 30 of FIG. 1. In these cases, the ticket vending machine 30 does not necessarily need to issue a two-dimensional code, and it is sufficient to install only the button 30B for selecting whether it is necessary or not. Also, in these cases, it may be configured to display the actions to be taken by the passengers according to the degree of remaining grooves of the tires, that is, in the manner shown in FIG. 9, on the display of the digital signage or on the paper sheet.

[0087] In the present embodiment, the remaining grooves of the tires are described as an example of the state of the vehicle to be measured, but it is not limited thereto. For example, as the state of the tires, scratches or air pressure of the tires may be measured.

[0088] In addition, in each of the above embodiments, the information processing that the CPU reads and executes software (program) may be executed by various processors other than the CPU. Examples of the processor in this case include a PLD (Programmable Logic Device) whose circuit configuration can be changed after manufacturing, such as an FPGA (Field-Programmable Gate Array), and a dedicated electric circuit such as an ASIC (Application Specific Integrated Circuit) having a circuit configuration designed specifically to execute specific processing. Further, the information processing may be executed by one of these various processors, or may be executed by a combination of two or more processors of the same type or different types (for example, a plurality of FPGAs, a combination of a CPU and an FPGA, etc.). More specifically, the hardware structure of these various processors is an electric circuit combining circuit elements such as semiconductor elements.

[0089] In addition, in each of the above embodiments, the mode in which the information processing program is pre-stored (installed) in the storage device has been described, but the present invention is not limited to this. The program may be provided in a form recorded on a recording medium such as a CD-ROM, a DVD-ROM (Digital Versatile Disc Read Only Memory), and a USB (Universal Serial Bus) memory. Further, the program may be in a form downloaded from an external device via a network.
