DETAILED DESCRIPTION OF THE INVENTION

[0001]

Field of the Invention The present invention relates to a tire management system and a consumable goods management system, and more particularly, to a tire management system and a tire management system capable of notifying a user in advance of a tire replacement time. The present invention relates to a management system for consumable supplies.

[0002]

2. Description of the Related Art A general user (driver) driving a passenger car determines an approximate time to replace a tire by looking at the slip sign of the tire or measuring the groove depth using a depth gauge as appropriate. They change tires, or change tires after the slip sign appears.

[0003]

Since commercial vehicles such as delivery trucks, buses, taxis, and the like have a long mileage per day, their tread wear is lower than that of tires mounted on ordinary home passenger cars. Is intense.

For this reason, the groove depth and air pressure are measured and recorded periodically (for example, for two to three months), and the tires are replaced based on the measurement results.

However, in this method, when measuring the groove depth, the groove depth may already be less than the service limit, or the groove depth may be lower than the service limit (legally, for example, the remaining groove depth is 1). .6 mm) cannot be accurately determined.

Accordingly, the depth of the groove is measured every time the vehicle travels for a certain distance, and a graph showing the relationship between the distance traveled and the groove depth is obtained. A method for calculating the traveling distance is described in, for example,
No. 82931. Further, a method of calculating the estimated life of a tire by calculating from the measured traveling distance and groove depth has been proposed in, for example, Japanese Patent Application Laid-Open No. 58-106405 and Japanese Utility Model Application Laid-Open No. 5-6348.

[0007] In a transportation company or the like having a large number of vehicles, there is a manager who manages the vehicles, and the manager sometimes records the traveling distance, groove depth, air pressure, and the like on a regular basis.

In the conventional method, it is only possible to know the mileage up to the tire life, and the driver periodically reports the value of the mileage meter to the manager, or the manager or the like periodically drives the vehicle. The meter reading had to be checked, and the management work was complicated.

[0009] Even a user of a general private passenger car sometimes forgets to see the slip sign of the tire and uses a tire whose usage limit has been exceeded.
