Technical Field

The invention relates to the technical field of automotive electronics, in particular to a tire pressure real-time monitoring device and system.

Background

In the field of automotive electronics, monitoring of tire condition is an important item, and the following are several existing tire pressure testing systems:

1. the Tire Pressure Monitoring System (TPMS) mainly uses a wireless transmission technology, and utilizes a high-sensitivity micro wireless sensing device fixed in an automobile Tire to directly or indirectly acquire, transmit and display data such as automobile Tire Pressure and temperature. The TPMS technology has the defects of long data reaction time, inaccurate monitoring, high false alarm rate and the like; the adoption of the wireless sensing technology also causes the signal to be interfered under certain environments, thereby causing the problems of multiple faults and the like in practical use.

2. The ABS tire pressure monitoring adopts an Anti-lock Braking System (ABS), which is called a wheel speed sensor for short, to compare the rotating speed difference between tires so as to achieve the effect of tire pressure monitoring. The monitoring result is only an estimation result, and can be monitored only when the tire pressure is seriously insufficient. When the alarm air pressure of the system is insufficient, the problem tires cannot be specifically displayed and need to be detected one by one. The system is not effective when the vehicle is stationary, traveling at low speeds, or traveling on a road surface with uneven pits. When the air pressure of four tires simultaneously goes wrong, the system can not inform, and in addition, the spare tire is easy to be mistakenly reported because the spare tire has no abrasion and the diameter is slightly larger.

3. The wired voltage measuring technology mainly adopts a conductive slip ring to complete the connection of the whole circuit. Compared with the TPMS, the wired pressure measurement technology has the advantages that the whole signal transmission process is conducted through a line, and the problems of signal loss, interference, long data response time, false alarm and the like are basically avoided. However, due to the wired design, when the motor is applied to an automotive electronic technology object, the circuit connection and installation between the rotor and the stator are difficult, the connection of the circuit by adopting the conductive slip ring with poor manufacturability is not stable enough, and the motor is easy to break down frequently in use.
