Vehicle tire blowout warning device and method based on electrical resistance dynamic tomography

Abstract

The invention discloses a vehicle tire burst early warning device and method based on resistance dynamic tomography. The device comprises 2N measuring electrodes, a conductive rubber ring arranged ona tire to be measured along a circumferential direction, and a stress measuring device, wherein the 2N measuring electrodes are uniformly arranged on the outer circumference of a hub along the circumferential direction, and the conductive rubber ring is arranged in a contact position between the tire to be measured and the hub; and one end of each measuring electrode is connected with the stress measuring device, and the other end of each measuring electrode is in close contact with the conductive rubber ring. The method comprises the following steps: measuring the stress distribution of the tire to be measured in a driving process according to a measuring time interval T, and performing tire burst early warning judgment according to the measuring result. A conductive layer of which the resistivity changes along with the stress is arranged on the tire to be measured along the circumferential direction, and the 2N measuring electrodes which are uniformly arranged on the hub along the circumferential direction and are in contact with the conductive layer are adopted to realize stress distribution measurement of the tire, so that tire burst early warning can be simply, conveniently and accurately preformed in real time.

Description

technical field [0001] The invention belongs to the technical field of vehicle safety monitoring, and in particular relates to a vehicle tire blowout warning device and method based on electrical resistance dynamic tomography. Background technique [0002] Automobiles have become one of the indispensable means of transportation for people to travel, and the safety and reliability of vehicles directly determine the safety of people's lives. Automobile tires are the main load-bearing parts of automobiles, and their safety cannot be ignored. At present, the car tire monitoring devices used on the market can only monitor the tire pressure during the driving process of the vehicle, but cannot provide early warning for early defects inside the tire, and cannot reflect the force on the tire during the driving process of the vehicle. In this case, the stress distribution of the tire cannot be given, the monitoring parameters are single, and the use effect is poor, so there are many...

Problems solved by technology

At present, the car tire monitoring devices used on the market can only monitor the tire pressure during the driving process of the vehicle, but cannot provide early warning for early defects inside the tire, and cannot reflect the force on the tire during the driving process of the vehicle. In this situation, the stress distribution of the tire cannot be given, the monitoring parameters are single, and the use effect is poor, so there are many safety hazards in the driving process of the vehicle, and it is impossible to achieve accurate tire blowout warning
