摘　　要：本文提出了采用Cirronet公司的WIT2450模块实现无线抄表系统的解决方案,微控制器采用德州仪器公司的超低功耗单片机MSP430,介绍了无线抄表系统中主站系统、中继系统和从站系统的硬件设计和软件设计,WIT2450采用跳扩频通信,系统具有较好的抗噪声和多经衰落性能。The paper has proposed a precept of wireless electronic meter reading system based on WIT2450. The design adopts TI MSP430 microcontroller which is featured by ultra-low-power. The paper has introduced the hardware design of base station, remote station and slave station, also the software design is introduced. Frequency hopping spread spectrum technology ensures maximum resistance to noise and multi-path fading.
