Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a tire pressure real-time monitoring device and system. Background technique [0002] In the field of automotive electronic technology, tire condition monitoring is a particularly important item. The following are several existing tire pressure testing systems: [0003] 1. Tire Pressure Monitoring System, referred to as TPMS, mainly adopts a wireless transmission technology, using a high-sensitivity miniature wireless sensor device fixed in the tire of the car to directly or indirectly collect, transmit, Displays data such as car tire pressure and temperature. TPMS technology has the shortcomings of long data response time, inaccurate monitoring, and high false alarm rate; the use of wireless sensor technology also leads to signal interference in some environments, which leads to problems such as frequent failures in actual use. [0004] 2. ABS tire pressure moni...

AI Technical Summary

Problems solved by technology

When the pressure of four tires has problems at the same time, the system cannot notify. In addition, when changing the spare tire, it is easy to misreport due to the slightly larger diameter of the spare tire without wear.

However, due to the wired design, it is difficult to connect and install the circuit between the rotor and the stator when it is applied in the automotive electronic technology. The conductive slip ring with poor workmanship is not stable enough to connect the circuit, and it is also prone to frequent failures.
