Description

  The present invention relates to a system for managing prediction and execution of air pressure filling and tire replacement / rotation based on tire pressure inspection and tire groove inspection.

  According to road tire inspection results (fiscal 2002) regularly conducted by the Japan Automobile Tire Association, the number of vehicles that have been inspected is 3,169 highways and 5,408 general roads. Of these inspection vehicles, 1,566 vehicles with defective tires (18,1% defective rate) were announced. Looking at each defective item, the worst defective rate was 6.9% for “pneumatic improper”, followed by “insufficient tire groove” 4.9% and “uneven wear” 4.3%. Looking at each vehicle group, the worst defective rate was “special vehicles” at 24.3%, followed by “freight cars” at 21.4% and “passenger cars” at 16.2%.

  Looking at the results of road tire inspections this time, the top items for poor tire maintenance are “pneumatic improper” and “insufficient tire groove”, and there are fewer accidents that may be caused by poor tire maintenance. In order to improve environmental problems by reducing fuel consumption, it is recognized that there is a need to raise the awareness of these “inadequate air pressure” and “insufficient tire grooves” and to manage tires in total.

  Under these circumstances, for individuals or corporations that own vehicles, especially for transportation companies and bus companies that own multiple vehicles, inspect and manage the timing of vehicle tire replacement and rotation, the state of low air pressure, etc. This is extremely important for safety reasons. Tire manufacturer's dealers who have been entrusted with vehicle management from an individual or a corporation regularly check the remaining groove of the vehicle tires, measure the air pressure, etc., determine the time to replace the tire and replace the tire. Yes. Conventionally, these managements have been performed by filling in a management form. However, such work is very complicated, and there is a problem of lack of reliability because omissions or errors occur. There is.

  In order to solve such problems, the applicant of the present application has developed a “tire replacement and rotation management system by inspecting tire grooves” and has already filed a patent application (see Patent Document 1). This system checks the remaining groove depth of individual tires mounted on vehicles such as buses and trucks at the start of inspection, and checks the tire groove wear depth that occurs according to the distance traveled during a specified measurement period. Using a computer to calculate the distance traveled per 1 mm of the remaining groove of the tire, and subtracting 3.2 mm of the remaining groove depth on the expressway from the average remaining groove depth of the tire during the measurement period Is multiplied by the distance traveled per 1 mm of the remaining groove of the tire to calculate the estimated life of the tire, the estimated life of the tire is divided by the predicted monthly travel distance to calculate the usable life of the tire, and the usable life of the tire Calculate tire replacement / rotation timing and cost estimate, and calculate tire replacement / rotation timing and history of individual tires installed in the vehicle based on cost estimation. The purpose is to prevent traffic accidents and promote sales of tires by recording data and displaying tire position display data that is changed by the rotation, and by notifying the user of the history data early. And

  The applicant of the present application has applied for a patent by developing a “tire pressure alarm” that is attached to a tire valve or a tubeless foil to visually recognize a decrease in tire pressure (see Patent Document 2). However, since this alarm is located around the head of the display body, the color is displayed only on a part of the head mirror surface of the hemispherical display body. In some cases, it is difficult to see from the window body. Therefore, a “tire pressure reduction warning adapter” in which this point is further improved has been developed and a patent application has already been filed (see Japanese Patent Application No. 2002-252922). This adapter is equipped with a display that can easily recognize the rate of decrease in tire pressure when the tire pressure decreases, and since it has a simple structure, it can be manufactured at low cost, and once it is attached to the valve base, It is possible to know the tire pressure status easily and easily so that it is only necessary to check with the eyes, and even a tire in a deep position like the inner tire of a multi-wheel tire can be easily The air pressure can be visually recognized.

    On the other hand, a “vehicle tire management method” is disclosed as a method for providing a method for performing tire management by accurately predicting / calculating tire replacement and rotation times (see Patent Document 3). This management method includes a tire sensor / information storage device having a sensor part for sensing / measuring a tire condition management item, and an information storage part for storing the measurement value, which are mounted on a vehicle tire or a peripheral part of the tire. Vehicle tire management method using a data processing device, wherein the data processing device is configured to input a measured value of a management item of a tire condition measured by the tire sensor / information storage device, and an input past The wear rate of the tread groove depth is calculated based on the measured values of the climatic condition data, and the timing of tire replacement or tire rotation is predicted.

  According to this method, by correcting the wear rate with various parameters, it is possible to accurately grasp the wear process of the tire tread and accurately predict / calculate tire replacement and rotation times. However, due to problems such as the reliability of the tire sensor / information storage device, manufacturing costs, maintenance costs, etc., it is not a practical method. It is not possible to easily take appropriate measures for the tire pressure management, that is, tire pressure management.

  In addition, “vehicle management system, used in this system” is a system aimed at avoiding situations that may interfere with the operations of customers such as shipping companies that outsource vehicle management such as tire replacement timing. "Management data input / output terminal and recording medium" are disclosed (see Patent Document 4). This system is a vehicle management system in which a management data input / output terminal provided at a plurality of vehicle management offices and a host computer for controlling a database are connected via a communication line or an information recording medium. Each management data input / output terminal includes means for inputting registration data for registering a vehicle, initial setting data, periodic inspection result data, remaining groove limit value and transferring it to a database, Based on the initial setting data and the periodic inspection result data, at least one of an estimated travelable distance until the tire usage limit is reached or a count result indicating the tire usage status is obtained.

  According to this tire management system, a plurality of vehicle management offices under the vehicle management company entrusted with management and the head office or branch office of the vehicle management company can comprehensively grasp the situation of the vehicle entrusted with management. However, if the operator does not look at the inspection result diagnosis table created after inspecting the vehicle, it is not only possible to find tires with abnormal air pressure for each vehicle, but also predict and respond to the decrease in air pressure. It is not easy to manage the implementation.

  Therefore, the present invention aims to manage the tire pressure in a simple and reliable manner with respect to the problem of “pneumatic improperness”, which is the worst tire maintenance failure rate. Furthermore, in order to comprehensively solve the problems of “pneumatic pressure inadequate” and “tire groove deficiency”, the object is to provide a tire total management system based on prediction and implementation by tire pressure inspection, tire groove inspection, It is possible to prevent traffic accidents and promote tire sales.

  In order to solve the above-mentioned problem, the device according to claim 1 is directed to an input unit for inputting tire pressure and groove inspection data, a storage unit for storing the inspection data, and a tire pressure based on the inspection data. A data processing unit comprising a data processing unit for creating management data for filling and tire replacement and rotation, and an output unit for outputting the management data, and for checking the tire air pressure, it is mounted on a tire valve or a tubeless wheel. A tire pressure reduction warning adapter is used, and the tire pressure reduction warning adapter includes a display body that can visually recognize a tire air pressure decrease rate when the tire air pressure decreases, and the tire air pressure decrease rate is 20 on the outer peripheral surface of the display body. % Is the upper limit gauge, and tire pressure charge is based on the rate of decrease in tire pressure at the time of inspection. The data processing unit, based on the tire air pressure filling value of each tire mounted on the vehicle stored in the storage unit and the tire air pressure decrease value corresponding to the passage of time, Data for predicting the timing of filling the tire pressure with an upper limit of 20% as the rate of decrease is created, and the data processing unit adds the two inspection data measured after a predetermined measurement period stored in the storage unit. Based on this, the travel distance per 1 mm of the remaining groove of the tire mounted on the vehicle is calculated, and the estimated life of the tire is calculated by multiplying the effective remaining groove value of the tire and the travel distance per 1 mm of the remaining groove of the tire. Divide the estimated life by the estimated monthly mileage to calculate the number of months that the tire can be used, and create data that predicts the timing and cost of tire replacement and rotation from the usable month of the tire. Data processing unit may create a data capable of comparing the embodiment with time and cost of the prediction of tire replacement and rotation based on historical data of the stored tire change and rotation in the storage unit.

  Further, the invention described in claim 2 is a system for managing prediction and execution of air pressure filling and tire replacement / rotation based on the tire air pressure inspection and tire groove inspection according to claim 1, wherein the management data includes the tire Tire pressure filling management data (1), tire pressure prediction and execution management data (2), tire replacement / rotation prediction and execution management data (3), and tire pressure reduction warning adapter using tire pressure reduction adapter It consists of management data (4) that centrally manages the history of exchange, rotation, and air pressure, and outputs each management data as a form.

  As described above, according to the present invention, when the tire air pressure decreases, the tire air pressure decrease rate can be visually confirmed to immediately check whether there is an abnormality, and the tire air pressure is managed in a simple and reliable manner. It becomes possible.

  In addition, the tire air pressure filling timing can be predicted to raise awareness of the problem of “inappropriate air pressure”, and the tire air pressure can be managed in a simple and reliable manner.

  Furthermore, tire total inspection based on prediction and implementation by tire pressure inspection and tire groove inspection which could not be solved by the conventional tire management system becomes possible, which leads to prevention of traffic accidents and promotion of tire sales.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings and tables.

  FIG. 1 is a conceptual diagram showing a mechanism of a tire total management system.

  As shown in FIG. 1, a data processing device 10 is installed at a sales office such as a tire manufacturer's store that has been entrusted with vehicle management from an individual or a corporation. Thus, it is connected to a plurality of terminal devices 30 for workers. The data processing device 10 includes a memory 15 for storing inspection data, history data, and the like, a data processing unit 14 for creating predetermined management data for tire replacement and rotation, and tire pressure filling, and for inputting and outputting various data. An input unit 11, an output unit 12, and an interface circuit 13 are provided.

  In the tire management system according to the present invention, an individual or a corporation that wants to manage a vehicle is a target customer. In the case of an individual, each vehicle is brought into the sales office and managed individually.However, in the case of a corporation, the transportation company or bus company that owns a considerable number of vehicles is the target. Visit and manage the company on a business trip. Therefore, since the worker terminal device 30 needs to send and receive inspection data, history data, and management data to and from the data processing device 10 at each business trip visitor, the worker terminal device 30 inputs and outputs various data. A portable terminal device that includes an input unit and an output unit for performing the connection and can be connected to the communication line 20 is preferable. Also, when a worker visits a company on a business trip using a compressor (pneumatic filler) or a tire changer-equipped vehicle, tire pressure filling, tire replacement / rotation is performed based on the prediction obtained by the tire management system. Can be implemented.

  Next, an example of tire management by tire pressure inspection will be described. This tire management is characterized in that a tire pressure check is performed using a tire pressure reduction warning adapter.

  FIG. 2 is an explanatory diagram showing a use state of the tire pressure reduction warning adapter.

  As shown in FIG. 2, 50 is a tire air pressure reduction warning adapter, 51 is an outer frame, 52 is a head, 53 is a specular body, 54 is a display, and 55a to 55d are reference lines.

  A valve core pressing portion (not shown) that presses the valve core of the tire valve to open the tire valve and introduces pressure air in the tire into a bellows member (not shown) is provided in the main body of the outer frame body 51. The head 52 of the airtight outer frame 51 is made of a transparent material. The mirror body 53 is attached to the upper surface of the bellows member. When the air pressure in the bellows member is reduced, the mirror body 53 is immersed in the mirror body 53 when the bellows member is contracted or pressed to move the mirror body 53 downward. The display body 54 appears, and the reduced state of the tire air pressure can be viewed from the head 52 of the outer frame body 51.

  Gauges (display of reference lines 55a to 55d) are provided on the outer peripheral surface of the display body 54 so that the pressure state of the tire air pressure can be quantitatively confirmed. That is, when the tire pressure is reduced by 5%, the upper surface position of the mirror body 53 is moved down to 55a (display level A: the reduction rate is less than 5%), and thereafter when the tire pressure is reduced by 10%, the position of 55b (display) Level B: Decrease rate of less than 5-10%), 55c position when reduced by 15% (display level C: Decrease rate of less than 10-15%), 55d position when reduced by 20% (display Level D: Decrease rate is set to 15 to 20%). In addition, the reference line display in a gauge is not limited to the example shown in the present Example, For example, you may provide two reference lines with a reduction rate of 10% and a reduction rate of 20%. .

  FIG. 3 is a flowchart showing a processing procedure of tire management by tire pressure inspection using a tire pressure reduction warning adapter.

  First, the tire pressure reduction warning adapter 50 is attached to the tire valve or the tubeless wheel (S10) so that the tire pressure check can be performed at any time. When checking the reduced state of the tire air pressure, the vehicle driver or the inspection operator can immediately check whether there is an abnormality by simply viewing the gauge of the display body 54 from the head 52 of the outer frame body 51. . When the gauge of the display body 54 displays a reduction rate of less than 10% (display level A or B) (S11), an abnormality check is performed as necessary (S12). When the gauge of the display body 54 displays a reduction rate of less than 10 to 15% (display level C) (S13), an abnormality check is performed as necessary (S12). At this display level C, it is not a situation that requires immediate air pressure filling, but it is desirable to perform air pressure filling early with an awareness of crisis management. When the gauge of the display body 54 displays a reduction rate of 15 to 20% (display level D) (S13), in order to prevent traffic accidents due to insufficient air pressure, the air pressure is quickly filled (S14). . Thereby, when the tire air pressure decreases, the rate of decrease in the tire air pressure can be visually confirmed to immediately confirm the presence or absence of abnormality.

  Next, when air pressure inspection and air pressure filling are performed, inspection data is input to the data processing device 10 (S15), and management data is created by the data processing unit 14 (S16). These inspection data and management data are stored in the memory 15, and are output to the form at the time of reporting (S17), and the check of the tire pressure filling is performed according to this (S18). An example of the management data of this case will be described based on Table 1.

  In Table 1, it is shown that the air pressure of the tire mounted for each vehicle number is set to 920 kPa. In the case of the vehicle number 18-79, the air pressure is reduced at the display level C. It shows that air pressure filling was performed and the air pressure at that time was 800 kPa. Then, the next air pressure filling was performed on February 10th when the air pressure was reduced at the display level D, and the air pressure at that time was 760 kPa. Further, it is shown that the next air pressure filling was performed on June 20 when the air pressure was reduced to the display level D, and the air pressure at that time was 750 kPa.

  Another example of tire management by tire pressure inspection will be described. This tire management is characterized in that a tire pressure filling time is predicted using a computer.

  FIG. 4 is a flowchart showing a processing procedure of tire management by tire pressure inspection using a computer.

  First, the air pressure is checked (S20), and the air pressure is filled (S21). Then, the inspection data is input to the data processing device 10 (S22).

  Here, based on the tire pressure filling value and the tire pressure drop value corresponding to the passage of time, the data processing unit 14 calculates a predicted value of the tire pressure filling timing with an upper limit of the tire pressure drop rate being 20%. Calculate (S23). Then, in accordance with the predicted value, management data that can compare the prediction with the implementation is created (S24). These inspection data and management data are stored in the memory 15, and are output to the form at the time of reporting (S25), and the check of the tire pressure filling is performed according to this (S26). An example of the management data of this case will be described based on Table 2.

  In Table 2, since it shows that the air pressure of the tire mounted for each vehicle number is set to 920 kPa, and the tire air pressure is estimated to decrease by 30 to 50 kPa every month, The tire pressure filling period is predicted to be 4 months so that the rate of decrease of the tire pressure when it is set to 40 kPa does not exceed 20%, and the pressure filling is performed periodically. In the case of the vehicle number 18-79, air pressure filling was performed on October 15, and the air pressure at that time was 800 kPa / decrease rate of 13%. The next air pressure filling time is predicted to be February 15th. On the other hand, the air pressure filling is performed on February 10th, and the air pressure at that time is 760 kPa / decrease rate of 17%. Yes. Furthermore, it is predicted that the next air pressure filling time will be June 10th. On the other hand, the air pressure filling was conducted on June 20, and the air pressure at that time was 750 kPa / decrease rate of 18%. Yes.

  In this embodiment, it is assumed that the tire pressure drop value corresponding to the passage of time is constant, and the tire pressure filling period is predicted to be four months. However, since the tire pressure drop value fluctuates due to the influence of the outside air temperature, it can be managed by providing a difference in the air pressure drop value in consideration of the temperature difference between summer and winter.

  Next, tire total management will be described. This tire total management is characterized in that tires are centrally managed based on management data of tire replacement, rotation, and tire pressure.

  FIG. 5 is a flowchart showing a processing procedure for total tire management.

  First, tire replacement and rotation management by tire groove inspection will be described.

  First, a groove inspection is performed at least twice after a predetermined measurement period (S30, S31), and these inspection data are input to the data processing apparatus 10 (S32).

  Here, the data processing unit 14 calculates the travel distance per 1 mm of the remaining groove of the tire mounted on the vehicle, and multiplies the effective remaining groove value of the tire and the travel distance per 1 mm of the remaining groove of the tire to estimate the tire. The lifetime is calculated (S33). Next, the estimated useful life of the tire is calculated by dividing the estimated life of the tire by the predicted monthly travel distance (S34). Then, a predicted value of the timing and cost of tire replacement and rotation is calculated according to the number of months that the tire can be used (S35), and management data that can compare the prediction with the execution is created according to the predicted value (S36). ). These inspection data and management data are stored in the memory 15, and are output to a form at the time of reporting (S37), and tire replacement and rotation execution are checked according to this (S38). An example of the management data of this case will be described based on Tables 3 to 7.

  As shown in Table 3, the vehicle mileage meter (297,985 km) was recorded at the time of the first tire inspection, and the individual tires mounted for each vehicle number (the tire mounting position is the upper column of Table 8). 2), the remaining groove depths of the two outer grooves and the two inner grooves are measured with a digital depth gauge, and these inspection data are input to the data processing device 10. In addition, the check and filling data of the air pressure of each tire is also input to the data processing device 10.

  The expected value in Table 3 is the remaining groove depth that can travel on an expressway from an average remaining groove depth of 15.9 mm when it is predicted to travel 6,000 km per 1 mm of the remaining groove depth of the tire. When the usable tire of 12.7 mm minus 3.2 mm is multiplied by 6,000 km, it becomes possible to travel 76,200 km, and if the monthly mileage is predicted to be 3,900 km, the remaining number of months of estimated tire life is It is about 20 months, and Table 3 shows that the remaining number of months for the six tires at the tire mounting position 3.4.5.5.6.7.8 is short, and the time for tire replacement is approaching.

  As shown in Table 4, at the time of the second tire inspection, the vehicle mileage meter (307,315 km) was recorded in the same manner as the first time, and two outer grooves of each tire mounted for each vehicle number. The remaining depth of the two inner grooves is measured with a digital depth gauge, and these inspection data are input to the data processing device 10. Also, the inspection data of the air pressure of each individual tire is input to the data processing device 10 in advance.

  In Table 4, the vehicle number 18-79 indicates that the vehicle mileage meter at the first inspection shows 297,985 km, and the accumulated vehicle at the second inspection measured at a predetermined appropriate period. Since the mileage meter shows 307,315 km, this indicates that the mileage during the measurement period is 9,330 km. Further, since the average remaining groove depth of the tire at the tire mounting position 1 at the second inspection is 14.8 mm, the difference from the average remaining groove depth at the first inspection measured in Table 3 is 15.9 mm. 1.1 mm is the wear depth of the tire groove during the travel distance of 9,330 km during the measurement period, and the travel distance of 8,113 km per 1 mm of the tire groove is calculated by dividing the travel distance of 9,330 km by 1.1 mm. Is calculated.

  The estimated life of the tire (the travelable distance of the tire) in the predicted values shown in Table 4 is calculated from the average remaining groove depth of the tire groove during the measurement period of 14.8 mm to the remaining groove depth which is the driving limit on the expressway. By subtracting 2 mm, the numerical value of 11.6 mm is multiplied by the running distance of 8,113 km per 1 mm of the tire groove to calculate 93,706 km. Further, the number of usable months of the tire is calculated to be 24 months by dividing the estimated life of the tire 93,706 km by the predicted monthly travel distance 3,900 km.

  As shown in Table 5, in the case of vehicle numbers 18-79 in Table 4, the tire replacement time is predicted immediately for the tire at the mounting position 8 where the number of usable months is 0 months in the inspection in June. Predicting that it is approaching, predicting that the usable month of the tire at the mounting position 6 is approaching July, one month later, and that the usable month of the tire at the mounting position 5 is 10 months after four months Predicting that it is approaching the moon, predicting that the usable month of the tire at the mounting position 4 is approaching November, 5 months later, and that the usable month of the tire at the mounting position 3 is 6 months later It is predicted that it is approaching December. Based on these predictions, it is shown that a total of six tire replacements including the tire at the mounting position 7 and the mounting position of 8.6.5.5.4.3.7 were performed in October.

  As shown in Table 6, the prediction and implementation of tire replacement costs correspond to those in Table 5. In Table 4, in the case of vehicle numbers 18-79, six tires with a unit price of 30,000 yen in October are listed. This shows that a total of 180,000 yen has been recorded.

  As shown in Table 7, tire replacement / rotation is predicted and carried out in October when vehicle number 18-79 in Table 4 is changed and the total mileage meter shows 316,235 km in October. Therefore, the estimated mileage (20.000 km) that needs to be rotated is predicted to be 336,000 km (March) shown in the accumulated mileage meter, and the accumulated mileage meter is 332,835. It shows that tire rotation was carried out in February when kilos were shown.

  Finally, tire replacement and rotation management by tire groove inspection and tire total management by tire groove inspection and tire air pressure inspection combined with the above-described tire management by tire air pressure inspection will be described.

  In the flowchart showing the processing procedure of the total tire management shown in FIG. 5, as described above, the data processing unit 14 calculates the predicted value of the timing and cost of tire replacement and rotation, and compares the prediction with the execution according to the predicted value. Management data to be obtained (S36), and by combining this management data with the management data acquired by the tire management method by the air pressure inspection, the data processing unit 14 can perform the tire management, rotation, and tire pressure centralized management data. Is created (S39). This unified management data is stored in the memory 15, and is output to a form at the time of reporting (S40), and a total check of tire replacement, rotation and air pressure filling is performed according to this (S41).

  Tire replacement and rotation and air pressure management resumes shown in Table 8 are the management data for tire replacement and tire rotation prediction and implementation shown in Tables 5 and 7, and tire pressure prediction and implementation management data shown in Table 2. The tire mounting position was 3.4.5.6.7.8 on October 15 when the cumulative mileage meter showed 316,235 km for vehicle number 18-79. This indicates that a total of 6 tires were replaced, and tire rotations of 4 tires 1-9 and 2-10 and 10 tire pressures were filled at the same time. At this point, the next prediction of tire rotation and tire pressure filling is displayed in the right column of the table. On February 10th, the total mileage meter showed 332,835 km, indicating that four tires 1-3, 2-4 tire rotation and ten tire pressures were filled. Show.

  As shown in Table 9, the tire replacement and rotation and tire pressure management resume (cost) correspond to Table 8, the amount of the tire replacement 180,000 yen on October 15, the amount of rotation 1,600 It shows that each yen was recorded.
