Abstract

The invention relates to equipment for automobile safety, and discloses a wireless charging monitoring device for automobile tire pressure. The monitoring device comprises automobile tire pressure sensors including a temperature sensor, a pressure sensor and an acceleration sensor, a voltage monitoring circuit, an A/D (Analog/Digital) conversion circuit and a microcontroller. The monitoring device is characterized in that a user can wirelessly charge the automobile tire pressure sensors by a wireless charger, the wireless charging part executes energy coupling through an inductance coil so as to realize energy transfer, and an electromagnetic induction circuit part also executes energy coupling and inputs energy. The monitoring device has the advantages that, in the case of under-voltage, the system executes under-voltage alarm, at this time, the user can wirelessly charge the tire pressure sensors through the wireless charger, so that long-term power supply is kept, although the device provided by the invention has very small volume and very low battery capacity, long-term work of the tire pressure monitoring system can be maintained, accidents of tire burst can be reduced, and serious traffic accidents can be reduced; and the monitoring device is efficient, and has remarkable technical progress.

Description

technical field [0001] The invention relates to a vehicle safety device, more specifically, to a wireless charging vehicle tire pressure monitoring device. Background technique [0002] At present, in the vicious traffic accidents, the car accidents caused by the blowout account for a very high proportion, and among the factors causing the blowout, one of the primary reasons is that the tire pressure is not monitored when the tire pressure is insufficient. Today, various countries pass corresponding laws and regulations to improve people's safety awareness. The United States has used legal means to force the installation of tire pressure monitoring systems since August 2007. The European Union requires that all European models install tire pressure monitoring systems in 2012. This all shows the importance of the tire pressure monitoring system. However, due to the tire pressure monitoring sensor system installed on the wheel tire, the volume of the device is very small, and...
