Valves are widely applied in many enterprises, its working condition is directly related to system security and economic effectiveness. Because the industrial characteristics of scattered field of the valve installation is not easy to wiring, using wireless transmission valve state parameter monitor broad prospects. This design of micro control unit adopts Si1000 is a RF chip integrated microprocessor and wireless transceiver module, and has advantage of low power consumption and long distance transmission, compared with most existing transceiver module working in 2.45GHz. In this paper it introduced a Si1000 based wireless status monitor hardware design of the valve, and develop the initialization of the MCU program monitors from standing between master station and communication program. The measured show that micro controller for Si1000 status monitor from the station, can meet the needs of the long-distance wireless communication with master station.%阀门在许多企业中应用广泛，其工况好坏直接关系到系统安全和经济效益.因为工业现场的阀门安装分散、不便于布线的特点，采用无线传输阀门状态参数的监控器前景广阔.微型控制器采用的Si1000是一款集微处理器和无线收发模块于一体的射频芯片，和现有大多数工作在2.45GHz的收发模块相比，它具有功耗低、传输距离远的优点.本文介绍了一个基于Si1000的无线阀门状态监控器的硬件设计，并开发了MCU的初始化程序、监控器从站与主站之间的通讯程序.实测表明，以Si1000为微控器的状态监控器从站，能够较好满足与主站远距离无线通信的需要.
