摘　　要：针对大多数直接式汽车胎压监测系统组件集成度低、体积和功耗较大等问题,提出了一种基于短距离无线通信ZigBee技术的新型胎压无线监测系统的设计。主要采用TI的CC2530芯片和英飞凌SP12集成式数字传感器,实现对汽车轮胎内部状态的实时监测。采用软硬件协同设计以降低系统功耗,并通过多点轮询通信方式和ZigBee高级加密设置保障了其无线通信的抗干扰能力。Since most traditional direct tire pressure monitoring systems have some shortcomings, such as low integration, large size and high energy consumption, a new design of wireless tire pressure monitoring system based on ZigBee technology is proposed. TI CC2530 chip and Infineon SP12 integrated digital sensor are used to achieve real-time monitoring of automobile tires internal state. Hardware and software co-design is adopted to reduce the system power consumption, while query communication and ZigBee advanced encryption setting can effectively ensure the antijamming capability of wireless communication of the system.
