Passive triggered tire pressure monitoring system and method

Abstract

The present invention is a passive triggered tire pressure monitoring system and method, the passive triggered tire pressure monitoring system mainly comprises a main machine, a plurality of triggers and a plurality of tire pressure sensors, the main machine are respectively connected with the plurality of triggers, the plurality of tire pressure sensors are respectively arranged tires of a car, the triggers are respectively arranged on the car body and in one to one corresponding to the tire pressure sensors on the tires, the tire pressure sensors are passively triggered by the corresponding triggers to detect and send tire pressure information to the main machine, since the tire pressure sensor are not always in operation, the power saving object can be achieved, and at the same time the problem that tire pressure sensors may interfere with each other during initiative sending of the information can be solved.

Description

technical field [0001] The invention relates to a tire pressure detection system and method, in particular to a passive trigger type tire pressure detection system and method. Background technique [0002] An existing wireless tire pressure detection system such as Figure 7 As shown, it is mainly composed of at least four wireless tire pressure sensors 81-84 and a wireless tire pressure receiving host 80, wherein each wireless tire pressure sensor 81-84 includes a controller and a sensing unit , a wireless transmitting circuit, a wireless receiving circuit and a power supply (not shown in the aforementioned components). When the wireless tire pressure sensors 81-84 are activated, they will regularly or irregularly use their transmitting circuits to transmit the tire information and their exclusive numbers detected by the sensing elements to the wireless tire pressure receiver in a fixed coded manner. Host 80. [0003] Since the aforementioned wireless tire pressure detect...

AI Technical Summary

Problems solved by technology

However, the wireless tire pressure sensors 81-84 are installed in a sealed way inside the tire, so the battery cannot be easily replaced after the power is exhausted, and the increase in the number of data transmissions in the aforementioned public case will increase the power consumption, which will make the wireless tire The power of the pressure sensors 81-84 is exhausted ahead of time, causing trouble

[0005] From the above, it can be seen that the existing wireless tire pressure detection system has not fully considered the correctness of the received tire pressure data and the consideration of power consumption efficiency, and further review is needed to seek a feasible solution
