When the save button 91 is touched, the information input in each of the above-mentioned input fields of the worker terminal 20 is input (uploaded) to the management server 30 and saved. In the present embodiment, by touching the save button 91, the information input to the inspection input screen 80 is transmitted to the management server 30 via the communication network 40, and the information received by the management server 30 is stored. Therefore, the communication unit 21 and the input unit 27 of the worker terminal 20 function as information input units. Further, the present invention is not limited to this, and for example, the management server 30 may be accessed on the worker terminal 20 and the corresponding information may be directly stored (stored) in the management server 30.

Further, the special note input button 92 is a button for describing matters (for example, damage to the tire) that the worker noticed during the tire inspection. The tire mounting position button 93 is a button for selecting one tire from a plurality of tires mounted on the vehicle, and is a button for selecting a tire to be inspected. Touching the tire mounting position button 93 switches to, for example, the input or selection screen of the mounting position number, and by inputting or selecting the mounting position number here, the remaining groove depth input field 83 of the input or selected tire number 83. You can enter information in. In this case, for example, when 1 is selected as the mounting position number, the remaining groove depth input field 83 corresponding to the mounting position number is displayed on the display unit 26, and information can be easily input to the input field 83. It becomes. When the mounting position number (1) is selected, for example, input of another mounting position number (2 to 6) that has not been selected to the remaining groove depth input field 83 is prohibited (input is not possible). Is preferable. According to this, it is possible to suppress erroneous information input as much as possible. Further, the vehicle search button 94 in the camera license plate shooting is a button having the same function as the vehicle search button 63 in the above-mentioned camera license plate shooting.

Next, the worker terminal 20 is communicably connected to the nearby depth gauge 50 by touching the depth gauge cooperation button 90 (step ST6). In this case, although not shown, the identification number of the depth gauge 50 connected to the inspection input screen 80 may be displayed.

Next, the worker terminal 20 is touched with the tire mounting position button 93 to select the mounting position number N (for example, N = 1) (step ST7). Then, the worker measures the remaining groove depth of the tire 2 using the depth gauge (step ST8). Specifically, since the tire mounting position corresponding to the selected mounting position number N = 1 is the front left, the worker uses a depth gauge to determine the remaining groove depth of each groove of the front left tire 2. Measure. In the present embodiment, when the tire 2 is attached to the vehicle, the groove numbers are defined as 1, 2, ... From the inside (inside) to the outside (outside) in the vehicle width direction, for example. Therefore, the worker measures each mounting position number in the order of the remaining groove depth of each groove from the inside in the vehicle width direction of the tire 2.

Then, every time the worker makes a measurement, he / she operates the operation unit 54 of the depth gauge 50 to transmit the measured remaining groove depth information of the groove to the worker terminal 20 (step ST9). In this case, the transmitted residual groove depth information is automatically input in the designated input field. Specifically, as shown in FIG. 11, the first point input field 84 is provided with input fields 84A to 84C corresponding to each groove number. When the remaining groove depth of the groove corresponding to the groove number 1 of the tire 2 is measured by the depth gauge 50 and the operation unit 54 is operated, the remaining groove depth information is automatically input to the input field 84A corresponding to the groove number 1. At the same time, the cursor moves to the input field 84B corresponding to the groove number 2, and the input standby state is set. Next, when the remaining groove depth of the groove corresponding to the groove number 2 of the tire 2 is measured by the depth gauge 50 and the operation unit 54 is operated, the remaining groove depth information is automatically input to the above-mentioned input field 84B. At the same time, the cursor moves to the input field 84C corresponding to the groove number 3 and enters the input standby state. Here, it is preferable that the input field in the input standby state is displayed in a different mode (color) from the others. In the present embodiment, when the remaining groove depth information corresponding to the groove number is transmitted from the depth gauge 50, the measurement information acquisition unit 24 acquires the transmitted remaining groove depth information and the remaining groove depth information. Is automatically entered in the corresponding input field. Therefore, input errors can be suppressed as much as possible. For example, if the automatic input to the input field fails, the worker touches the correct input field to put the input field in the input standby state and put the numeric keypad on the inspection input screen 80. It is also possible to display 88 and input the remaining groove depth information in the input field using the numeric keypad 88.

Next, the worker determines whether or not the measurement point is the first point (step ST10). As described above, in the present embodiment, the remaining groove depth is measured at two different points for each groove. Therefore, if it is the first point (step ST10; Yes), the process is returned to step ST8 to execute the measurement and transmission operation. At this time, a check box 87 is checked when inputting the second groove depth shown in FIG. As a result, it is preferable that the input to the second point input field 85 is possible and the input to the first point input field 84 is prohibited. If it is not the first point (step ST10; No), the process proceeds to step ST11.

Next, the worker determines whether or not the measurement of all the tires (six in the example of FIG. 1) has been completed (step ST11). Specifically, it is determined whether or not the measurement information has been input in the input fields of all the mounting position numbers on the inspection input screen 80. In this determination, if the measurement of all the tires 2 is not completed (step ST11; No), the process is returned to step ST7 and the next tire mounting number is selected. If the measurement of all the tires 2 is completed (step ST11; Yes), the worker touches the save button 91 (step ST12). As a result, the information (data) entered in each input field of the inspection input screen 80 is transmitted to the management server 30. When the management server 30 receives these information, the management server 30 adds and stores the received information to the vehicle information and the information about each tire mounted on the vehicle. This ends the explanation of the operation, but if there is another vehicle to be inspected, the process can be executed from step ST3 by touching the vehicle search button 94 in the camera license plate shooting.

Next, the operation of the tire wear prediction unit 36 of the management server 30 will be described. FIG. 12 is an example of a tire wear prediction graph created by the tire wear prediction unit 36. The tire wear prediction unit 36 creates, for example, a tire wear prediction graph each time information on the remaining groove depth of the tire 2 is newly input. In this tire wear prediction graph, the tire 2 has a limit groove depth (discarded) based on the remaining groove depth information of at least two or more tires 2 at different times and the mileage between them for the same tire 2. It predicts the mileage until it wears to the groove depth). The tire wear prediction graph is created for each tire (mounting position) mounted on the vehicle. The created tire wear prediction graph can be confirmed, for example, by a vehicle manager of a user company or the like logging in to the management server 30 via the communication network 40. In addition, normally, the staff of a tire manufacturing and sales company or a directly managed store prepares a report including the above tire wear prediction graph, and by submitting this report to a user company, the tire wear prediction graph can be confirmed. .. This helps the user company to create a schedule for replacing and rotating the tire 2. When creating this tire wear prediction graph, it is preferable to add the air pressure information of the tire 2 to the residual groove depth information of the tire 2 for examination. For example, when traveling in a state where the air pressure is lower than the reference air pressure, uneven wear occurs in the tire, so that more accurate tire wear prediction can be performed by adding the air pressure information.

As described above, the tire management system 100 according to the present embodiment has a management server 30 that manages information about the tires 2 mounted on the plurality of vehicles 1 registered in advance, and a worker carrying the tire management system 100 when inspecting the tires of the vehicle 1.

Further, since the remaining groove depth information of the tire 2 is acquired in association with the tire mounting position and these are input to the information regarding the tire 2 of the management server, the measured remaining groove depth information of the tire 2 can be easily obtained. Moreover, it can be accurately input to the management server 30.

Further, since the measurement information acquisition unit 24 acquires the residual groove depth information measured by the depth gauge 50 via the short-range wireless communication network, a paper or the like for describing the measured information becomes unnecessary, and the load of inspection work is increased. Can be mitigated.

Further, when the position number indicating the tire mounting position is selected, the measurement information acquisition unit 24 acquires the remaining groove depth information of each groove of the tire corresponding to this position number, so that the remaining groove depth of the tire 2 is obtained. The information can be easily and accurately associated with the tire mounting position.

Further, since the measurement information acquisition unit 24 sequentially acquires the remaining groove depth information of the groove corresponding to the groove number indicating the groove position in each tire 2, the groove position and the remaining groove depth information can be easily and accurately obtained. Can be associated.

Further, since the worker terminal 20 includes a customer search unit 29A that searches for a nearby company name at the current position based on the detected current position information, the inspection owned by the company is performed by searching for the company name first. The search process for the target vehicle is reduced, and the vehicle can be searched at an early stage.

Further, the worker terminal 20 has a display unit 26, a vehicle search screen 70 for searching the vehicle 1 to be inspected on the display unit 26, and information on the tire 2 of the searched vehicle 1, and the groove depth information of each tire 2.
