[0012]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic diagram including an apparatus for carrying out the tire inspection method of the present invention.
In the figure, a tire inspection device 1 of the present embodiment includes a server computer 2 that stores tire / vehicle information about inspection target vehicles A, B, C ..., Information via the server computer 2 and a network N such as the Internet. And a plurality of portable computers 3 that are provided so as to be able to take in the tire / vehicle information of the server computer 2 via the client computer 4 and that are portable.

The server computer 2 is capable of providing and receiving information to a plurality of computers connected to the network N, and is not particularly limited, but for example, a large computer is suitable. The server computer 2 also includes a storage device that stores the tire / vehicle information. In FIG. 2, the tire
An example of the content contained in vehicle information is shown.

The tire / vehicle information is exemplified to include four main databases in this embodiment. The first is a customer database, in which information necessary for managing a plurality of customers who are the targets of inspection is recorded. For example, in addition to the “customer code number” or “customer name” to which a specific code is assigned to identify the customer, necessary customer addresses and the like are included. FIG. 3 shows an example in which one record of this customer database is displayed on the monitor.

The second is a tire / vehicle database. This tire / vehicle database includes, for each customer managed by the customer database, necessary information about the vehicle owned by the customer and the tires mounted on the vehicle. For example, "Vehicle number" registered with the Land Transport Bureau, "Vehicle number" that is the customer's vehicle management number, "Vehicle manufacturer name" that is the vehicle manufacturer name, taxi, private vehicle, sediment transport vehicle "Use category", which is a special application, "main road surface" on which the vehicle mainly runs,
"Maximum load capacity" that can be loaded, "Tire installation date" with new tires (or recycled tires), "Tire size",
"Tire pattern" that identifies the tire pattern shape by code number, "New or refurbished category" for distinguishing whether a new tire is installed or a refurbished one is installed, or the location of the tire with respect to the vehicle Information such as "arrangement of tires" indicating the above may be included.

Further, this tire / vehicle information database includes "customer code number" as an item common to the customer database. Therefore, this item can be used to cross-reference two databases. Also tires
In the example of FIG. 2, the vehicle information database includes two pieces of information, “tire A” and “tire B”. This is because when one vehicle includes two types of tires having different patterns or sizes, the individual tires are managed separately.

FIG. 4 shows an example in which one record of the tire / vehicle database is displayed on the monitor. In the information of "tire arrangement", the position of each of the four tires 01 to 04 with respect to the vehicle is displayed as an image. Here, it is also shown that the tires 03 and 04 are surrounded by a double frame and are driving wheels.

The third is an inspection database. As shown in FIG. 2, this inspection database records the inspection results of tires and the like on each inspection day for each vehicle owned by the customer. For example, as the information recorded on one inspection day, "inspector" who inspected, "mileage" which is the reading of the vehicle running meter, "remaining groove depth of tire" at the time of inspection, at the time of inspection Information such as "tire damage", "uneven wear", and "internal pressure" is recorded. In addition, this inspection database includes the customer database, tires,
Item "Customer code number" common to the vehicle information database
And “vehicle number” are included, and these databases can be used to refer to each other.

FIG. 5 shows an example in which one record of such inspection data is displayed on the monitor. For each of the tires 01 to 04 shown in the tire layout diagram, the information on the remaining groove depth, the presence or absence of external damage, the presence or absence of uneven wear, and the internal pressure is recorded. Regarding the depth of the remaining groove, as shown in FIG. 7, four grooves G1 to G are provided from the vehicle outer side to the vehicle inner side of the tire T.
Although the case where the measurement is performed in 4 is shown, it is possible to appropriately increase or decrease the number of measurement points.

The fourth is an analysis database. In this analysis database, various analysis results obtained by the calculation described below from the results of the inspection database and the like are recorded for each tire. For example, "average groove depth", which is the average value of the remaining groove depth measured at multiple positions, "wear resistance performance", which is the travelable distance per unit wear amount, and was arbitrarily specified after the inspection date. Information such as “estimated amount of remaining groove depth on a designated day”, which is the remaining groove depth on a day, and “tire life” on which a day when tire replacement is required are estimated may be included.

In this example, the data structure is as described above, but it is not limited to this, and it goes without saying that the data can be recorded in various modes. In addition to the above,
Necessary master files, index files, etc. can be prepared in advance.

The client computer 4 is preferably installed in each business office. Then, by exchanging the interface I and the network N, necessary information can be exchanged (transmitted and received) with the server computer 2. Therefore, the server computers can be accessed from the sales offices all over the country. The client computer 4 includes a monitor and, if necessary, is provided with a printer PR or the like so that the captured information can be printed appropriately.

The portable computer 3 is, for example, a palm-sized portable terminal type computer (so-called PDA; Personal Digital Assass) that is portable.
istant) 3a and a notebook computer 3b are preferably used. FIG. 6 shows a portable terminal type computer 3a.
An example of the above is enlarged and shown. This is a display unit 3A made up of a liquid crystal panel or the like for visually displaying information, an input unit 3B made up of input keys for entering information, a storage unit for storing information, and It has a control unit (which is arranged inside and is not shown) for controlling, and is portable because it is small and driven by a battery.

Further, in the present embodiment, such a portable computer 3 is provided with a groove depth measuring tool 5 capable of communicating to measure the remaining groove depth of the tire of the vehicle to be inspected. The groove depth measuring tool 5 is configured to include, for example, a small-sized main body portion 5a that can be gripped by an inspector, and a tracing stylus 5b that is formed to project on the tip side of the main body portion 5a. The tracing stylus 5b is provided so as to be movable back and forth with respect to the main body 5a, and is biased and supported in such a direction as to always project from the main body 5a. In addition, a potentiometer (not shown) capable of detecting the amount of advance / retreat of the tracing stylus 5a is built in the main body 5a. The signal from the potentiometer is digitized by the A / D converter.

A method of using such a groove depth measuring tool 5 is shown in FIG.
Shown in. First, the tip of the probe 5a of the groove depth measuring tool 5 is brought into contact with the groove bottoms of the grooves G1 to G4 of the tire T. Next, the tip portion of the main body portion 5a is pushed into the tire side so as to come into contact with the tread surface Ta. As a result, the amount of advance / retreat of the tracing stylus 5a with respect to the main body portion 5a is determined according to the groove depth, and a predetermined calculation can be performed based on this to electrically detect the groove depth of the tire T.

The information on the groove depth detected by the groove depth measuring tool 5 is predetermined in the portable computer 3 via the cable C such as RS-232 or a wireless interface (not shown) in this example. Is input in the format of, and the portable computer 3 stores this value.
In this way, by connecting the portable computer 3 and the groove depth measuring tool 5 so that they can communicate with each other, the operation of copying the measurement result of the groove depth on a data sheet or the like can be taken into the portable computer 3 without any work. Therefore, in addition to improving workability, it is useful for preventing transcription errors.

Next, an example of an inspection method performed by using such an apparatus 1 will be described based on the flowchart shown in FIG. First, the customer to be inspected is specified (step S1). This step is usually performed in a business office or the like where the client computer 4 is installed. When identifying the customer, for example, it may be performed according to a predetermined inspection schedule,
It is also possible to search the server computer 2 using the client computer 4 and extract and specify a customer who owns a tire whose life is approaching. Further, when a tire that is near the tire life appears on the server computer side (for example, the number of days until the tire life is less than 30 days, etc.) appears, the step of causing the client computer 4 of the sales office that manages the customer to send information prompting for inspection It is also good to set. As a result, it is possible to efficiently specify the customer who needs the inspection with priority.

Next, the tire / vehicle information of the specified customer is fetched from the server computer 2 to the client computer 4 (step S2). This captured information includes information on the customer database, tire / vehicle database, inspection database, and analysis database. Next, the tire / vehicle information fetched by the client computer 4 is fetched by the portable computer 3 (step S3). The connection interface between the client computer 4 and the portable computer 3 can be performed in various modes such as a wired system using a cable, a wireless system, and a system in which a storage medium is interposed. The information taken into the portable computer 3 can be appropriately displayed on the display unit 3A, and can be freely referred to by the person in charge of inspection. Therefore, the type and pattern of the vehicle owned by the customer and the tire to be inspected can be quickly confirmed prior to the inspection, and the inspection preparatory work can be streamlined. In particular, by including the estimated amount of the remaining groove depth on the specified date in the information captured by the portable computer 3, the tires to be inspected with particular attention can be grasped in advance. Enables optimum inspection work.

Next, the inspector holds at least the portable computer 3 and the groove depth measuring tool 5 to visit the customer and perform the inspection process (step S4). FIG. 9 shows an example of a specific procedure of the inspection process. In the inspection process, first, the groove depth measuring tool 5 is connected to the portable computer 3 (step S4).
1) The portable computer 3 is caused to display the tire layout of the vehicle to be inspected (step S42). FIG. 10 shows an example of the display unit 3A that displays the tire layout on the portable computer 3. The display section 3A also displays an input field for inputting a person in charge of inspection, an inspection date, and a current traveling distance, and a tire layout diagram is visually displayed.

Further, in the present example, in the tire layout diagram arranged in the portable computer 3, a warning is given to a tire having a small remaining groove depth (in this example, the tire is "03" and is marked with a dot). Is displayed. Although not particularly limited, the warning is given by highlighting a tire having a remaining groove depth equal to or less than a threshold value or changing a display color. Further, the threshold value can be set appropriately. Such a display is useful for effective inspection work such as inspecting the warned tire more carefully.

Next, one tire to be measured is selected from the tire layout displayed on the portable computer 3 (step S43). The tire may be selected, for example, by inputting the tire number from the input unit 3B, or when the display unit 3A is a touch panel type, by touching the display portion of the tire to be selected. be able to.

Next, the groove depth of the selected tire is measured using the groove depth measuring tool 5, and the result is input to the portable computer 3 (step S44). The measurement is performed as described above, and the measured value is automatically sent to and stored in the portable computer 3 via a cable or wireless. In this example, as shown in FIG. 5, for each tire, four positions 01 from the vehicle outer side to the vehicle inner side are provided.
The depth of the remaining groove is measured at ~ 04.

Further, for the selected tire, for example, the appearance condition such as a block on the tread surface, cracks, discoloration, etc. and uneven wear condition such as shoulder drop wear, heel & toe wear are visually observed, and the internal pressure of each tire is checked. Are measured and the respective information is input to the portable computer 3. These are input to the portable computer 3 from the input unit 3A each time, and the values are stored in the storage unit.
Further, for example, an internal pressure measuring tool (not shown) can be connected to the portable computer 3, and the internal pressure value measured similarly to the groove depth measuring tool 5 can be automatically taken into the portable computer 3. Then, steps S43 to S47 are performed until the measurement is performed for all the tires.
Repeat. Note that the appearance, uneven wear, and internal pressure of the tire can be measured separately from the groove depth.

Further, in the present embodiment, in order to perform the inspection more accurately, the remaining tires are identified for the first time by specifying any tire from the tire layout drawing displayed on the display portion 3A of the portable computer 3. It is configured to be able to collect, that is, to measure and input the groove depth information of the. As described above, tire selection is an essential condition for information input, so that incorrect input can be prevented and inspection accuracy can be improved.

When all the tires are inspected, the information collected by the inspection is transmitted from the portable computer 3 to the client computer 4 (step S5). On this occasion,
Various interfaces such as cable connection or wireless system can be adopted. The information may be sent after returning to the sales office, or when a line such as PHS is used, the information can be sent from the inspection site to the client computer 4 in real time.

The client computer 4 confirms the information obtained from the portable computer 3 and, if necessary, adds or corrects the information. Then, the information obtained by this inspection is transmitted to the server computer 2 (step S6). The server computer 2 adds the information transmitted from the client computer 4 to the tire / vehicle information stored in the storage unit, and predicts at least the life of the tire based on the added tire / vehicle information. (Step S)
7).

FIG. 11 shows an example of the processing procedure of the analysis processing. 12 and 13 show examples of analysis results.
The analysis process is performed by the server computer 2 in this example. First, the "average groove depth" and "actual mileage" of the tire are calculated based on the inspection database (steps S71 and S72). The "average groove depth" of the tire is obtained by averaging the respective depths measured at the four points. The “actual mileage” is the mileage from the time when a new (or retreaded) tire is mounted.

Next, the wear resistance performance is calculated (step S73). The wear resistance performance is a travelable distance per unit wear amount as described above, and is calculated by the following formula. Abrasion resistance performance (km / mm) = actual mileage (km) / tire wear amount (mm) The "tire wear amount" is calculated by subtracting the average groove depth during inspection from the groove depth when new. Calculated. 12
In the example shown in, the wear resistance performance of the tire A on July 1, 2000 is about 1093 because the actual mileage is 7,000 km and the tire wear amount is (15.2-8.8) mm.
It becomes km / mm. In the example of FIG. 12, the wear resistance performance was 1081 km in the previous inspection (April 1, 2000).
/ Mm, which can be confirmed as a slight improvement.

Next, the tire life is calculated (step S74). The law (safety standards for road transport vehicles) prohibits running on tires with a residual groove of 1.6 mm or less, so in this example, the remaining groove depth of the tire will be 1.6 mm due to future use. Calculate the expected life as the tire life. FIG. 14 is a graph showing changes in the remaining groove depth. The vertical axis represents the remaining groove depth (mm) of the tire, and the horizontal axis represents the actual travel distance. As shown in the figure, the depth of the remaining groove decreases as the actual travel distance increases. The case where the inspection result is applied to this graph is shown by a straight line.

The tire life can be calculated, for example, as follows. First, from the current average groove depth, 1.
Subtract 6 mm and calculate the wear allowance until tire replacement.
Next, the obtained wear resistance performance is multiplied by this wear allowance to calculate the travelable distance before tire replacement. And
This mileage can be calculated from the actual mileage and the inspection date 1
The number of days that can be traveled is obtained by dividing by the average traveled distance per day. By adding the number of runnable days to the inspection day, the day when the tire needs to be replaced, that is, the tire life b (shown in FIG. 14) is obtained. By law, the groove depth is 3.2 mm.
Because it is prohibited to drive on the highway with the following tires,
In addition to the tire life that the groove depth is 1.6 mm, 3.2 mm
The estimated highway prohibition date a (shown in FIG. 14) and the like can be calculated by the same procedure. In the tire analysis table (2) of FIG. 13, the depth of the remaining groove of the tire is 1.6 mm, 3.2.
mm, respectively, and the date and the mileage that the odometer will indicate are also displayed.

When the analysis step is completed, the server computer sends this result to the client computer 4 (step S8). Then, the client computer 4 makes various proposals to the customer based on this result. The analysis tables shown in FIGS. 12 and 13 are appropriately printed in a predetermined format and can be used as a document to be distributed to customers.
