Dynamic tyre pressure monitoring auxiliary engine and dynamic tyre pressure monitoring bridge

Abstract

The dynamic vehicle tire pressure monitoring auxiliary machine is equipped with a tire pressure sensor on the tire. It is characterized in that it is equipped with a monitoring microprocessor circuit, a wireless data communication circuit and a miniature inertial generator. The miniature inertial generator is a tire pressure sensor and a monitoring microprocessor. The circuit of the tire pressure sensor and the wireless data communication circuit are powered; the output of the tire pressure sensor is connected to the monitoring microprocessor circuit; the integrated micro-electromechanical device composed of the tire pressure sensor, the monitoring microprocessor circuit, the wireless data communication circuit and the micro inertial generator is installed in the In the same shell, a tire pressure monitoring auxiliary machine is formed, and the auxiliary machine is installed at the center of the wheel hub; the output of the wireless data communication circuit is transmitted to the vehicle host through the wireless data communication circuit and the network bridge. The network bridge is equipped with a wireless communication chip and a DCPL-Bus bus circuit. The invention can detect the tire pressure at any time and adjust the pressure to improve the safety of the vehicle. It will significantly improve the accuracy of tire pressure measurement and eliminate the hassle of battery replacement.

Description

technical field [0001] The invention relates to a vehicle safety device, in particular to a dynamic vehicle tire pressure monitoring auxiliary machine and a dynamic vehicle tire pressure monitoring network bridge used in connection therewith. Background technique [0002] Tires are the key components required for the operation of automobiles, and the failure of tires during the operation of automobiles is very likely to cause serious traffic accidents. In the process of high-speed driving, tire failure is the most worrying and most difficult to prevent for all drivers, and it is also the main reason for sudden traffic accidents. According to statistics, 70% of traffic accidents on highways in China are caused by flat tires, and in the United States, the proportion is as high as 80%. How to prevent the tire pressure from being in an abnormal range or even a puncture has become an important issue for safe driving. According to the analysis of experts from the National Rubber...

AI Technical Summary

Problems solved by technology

Therefore, the tire pressure monitoring device installed in the tire needs to be powered by a special micro-lithium battery, and the life and reliability of the micro-lithium battery greatly reduces the reliability of the entire monitoring system; it is very difficult to replace the micro-lithium battery with the tire

At the same time, because the tire pressure monitoring device installed in the tire changes according to the synchronous position of the outer circle of the wheel rotation, the tire pressure monitoring device is affected by centrifugal acceleration, and the accuracy of tire pressure measurement is not high. The error is large
