A wireless tire pressure monitoring system powered by a friction nanometer generator and a battery in a hybrid mode comprises the friction nanometer generator, a pressure and temperature detection module, a sensor MCU, an RF module, the lithium battery, a switch control circuit and a voltage stabilizing circuit. The friction nanometer generator passes through the rectifier and then is connected to two ends of the super capacitor and the voltage stabilizing circuit in parallel; and the voltage stabilizing circuit and the battery supply power to the pressure and temperature detection module, the sensor MCU and the RF module which are connected in series through the switching circuit. The system is slightly modified on the basis of an existing commercial tire pressure monitoring device, the stability and the practicability are better, and the service life of the built-in tire pressure sensor can be effectively prolonged. The structure is smaller and simpler, and the market prospect is good.

    一种摩擦纳米发电机和电池混合供电的无线胎压监测系统,包括摩擦纳米发电机、压力温度检测模块、传感器MCU以及RF射频模块、锂电池、开关控制电路、稳压电路。摩擦纳米发电机通过整流器后并联在超级电容和稳压电路两端;稳压电路和电池通过开关电路给串联的压力温度检测模块、传感器MCU以及RF射频模块供电。该系统在已有商业化胎压监测装置的基础上进行较小的改动,稳定性实用性更好,可以有效地延长内置型胎压传感器的使用时间。结构更加的小巧简便,市场前景好。
