Tire pressure monitoring system and device

Abstract

The invention discloses a tire pressure monitoring system and a tire pressure monitoring device. The tire pressure monitoring system comprises the tire pressure monitoring device and a data acquiring device, wherein the tire pressure monitoring device is used for monitoring a tire parameter in real time, recording primary state data into an internal memory of the tire pressure monitoring device and sending the state data to the data acquiring device when the tire parameter reaches the preset value; the data acquiring device is used for acquiring the state data including recording time and tire parameters. According to the tire pressure monitoring system and the tire pressure monitoring device, the tire parameters including the pressure and the like can be monitored in real time, thus achieving real-time monitoring and pre-warning purposes; a driving state of an automobile in a certain time and the situation changes of the parameters including the pressure, the temperature, the accelerated speed and the like can be recorded, so that the track record to the driving state of the automobile is realized, and the stability and the reliability are improved; meanwhile, the system and the device can further play helping roles in the driving state analysis, troubleshooting and the like of the automobile after an event and even play certain reference roles in the accident cause affirmation of vehicles.

Description

technical field [0001] The invention relates to the technical field of tire pressure monitoring, in particular to a tire pressure monitoring system and device. Background technique [0002] When a car is running at high speed, tire failure is an important reason for sudden traffic accidents. According to statistics, 70% of traffic accidents on Chinese expressways are caused by blown tires, while in the United States this proportion is as high as 80% %. How to prevent tire blowouts has become an important topic for safe driving, and maintaining standard tire pressure while driving and finding tire leaks in time are the key to preventing tire blowouts, and the tire pressure monitoring system (TPMS) is undoubtedly an ideal tool. [0003] The tire pressure monitoring system is mainly divided into two types, one is the indirect tire pressure monitoring system (WSBSTPMS) which obtains the tire pressure indirectly by detecting the wheel speed; the other is the direct tire pressure...

Problems solved by technology

[0004] However, although the existing tire pressure monitoring system can monitor and warn the tire pressure in real time, it does not have the function of data recording. When the receiving equipment of the car is powered off, the car breaks down or an accident occurs, it will completely lose its function. Therefore, the function of the existing tire pressure monitoring system is not perfect enough
