Tire internal temperature pressure detection device and detection method

Abstract

Belonging to the field of tyre temperature and pressure detection, the invention in particular relates to a tyre internal temperature and pressure detection device and a detection method. The detection device includes a temperature sensor and a pressure sensor arranged in the tyre, the temperature sensor is a wireless temperature sensor, and the pressure sensor is a wireless pressure sensor. The device also includes a wireless signal transmitter, a wireless temperature acquisition unit, a wireless pressure acquisition unit and a controller. The wireless temperature sensor transmits the acquired temperature signal to the wireless temperature acquisition unit through the wireless signal transmitter, the wireless pressure sensor transmits the acquired pressure signal to the wireless pressure acquisition unit through the wireless signal transmitter, and the wireless temperature acquisition unit and the wireless pressure acquisition unit are in connection with the controller. The wireless temperature acquisition unit transmits the acquired temperature value to the controller, and the wireless pressure acquisition unit transmits the acquired pressure value to the controller. The detection device is simple in structure, and users can visually judge the temperature and pressure change conditions at each test point and control vehicle running in time.

Description

technical field [0001] The invention belongs to the field of tire temperature and pressure detection, in particular to a tire internal temperature and pressure detection device and detection method. Background technique [0002] During tire production (mainly vulcanization process), performance test (mainly high-speed, durability and road test and other performance tests) and normal driving, the temperature and pressure inside the tire are parameters that researchers and users are more concerned about. At present, except for the temperature test of the vulcanization process, the test for this is still in a blank state. [0003] In the tire vulcanization process, temperature, pressure and time are the three elements that affect the tire vulcanization process; to ensure the vulcanization quality of the tire, it is necessary to ensure the appropriate vulcanization temperature, pressure and time, all of which are indispensable. At present, in the actual production process of ti...

Problems solved by technology

The high temperature causes the tire rubber to age, the fatigue strength decreases, and the tread wears violently, which is an important factor that may cause a tire blowout.
