本系统由胎压监测模块和中央监视模块两部分组成。胎压监测模块安放在轮胎内用于检测轮胎压力后经无线模块传输给位于车内的中央监视模块。胎压监测模块由控制器单片机，气压传感器和，电源模块和无线发射模块组成；中央监视模块由控制器单片机，液晶，声光报警装置，电源模块和无线接收模块组成。系统硬件框图如下。(The system consists of two parts: tire pressure monitoring module and central monitoring module. The tire pressure monitoring module is placed inside the tire to detect tire pressure and transmit to the central monitoring module in the vehicle via wireless module. The tire pressure monitoring module consists of a microcontroller, a pressure sensor and a power supply module and a wireless transmitter module. The central monitoring module is composed of a microcontroller, a liquid crystal, a sound and light alarm device, a power supply module and a wireless receiving module.)
