Patent Images
1. A tire information management system used for a mining site, comprising:
- a sensor configured to measure conditions of a tire attached to each of a plurality of vehicles for transporting mineral resources;
a tire information management apparatus configured to receive, by radio, a measurement transmitted by the sensor, and to transmit, to one of the vehicles that the measurement comes from, deterioration restraint information for restraining progress of deterioration of the tire, in a case where the received measurement is not within a predetermined allowable range; and
a calculate means that calculates in-use pressure IP1 based on a temperature measurement TI, a pressure measurement PI, and an average temperature TA at the mining site for a current month;
wherein the allowable range is determined based on the in-use pressure IP1,wherein the allowable range is determined by a comparison between the in-use tire pressure IP1 and a target internal tire pressure IP2, andwhereinthe allowable range for a tire containing liquid for cooling the tire is determined by the following equations;

Abstract
A tire information management system used for a mining site including a sensor configured to measure the condition of a tire attached to each of a plurality of vehicles for transporting mineral resources. A tire information management apparatus is configured to receive, by radio, a measurement transmitted by the sensor, and to transmit, to one of the vehicles that the measurement comes from, deterioration restraint information for restraining progress of deterioration of the tire, in a case where the received measurement is not within an allowable range.
