摘　　要：介绍了通过ARM芯片实现电参数的无线采集系统,主要阐述了系统软硬件结构以及嵌入式Linux系统中驱动程序的开发过程。该系统以EP9302为核心器件,用MAX1305ECM实现A D转换,通过基于IEEE802.11b协议的USB无线网卡MA111实现电压、电流、有功功率、无功功率、功率因素等电参数的无线传输。A wireless ARM embedded system, which can detect electrical parameters, is introduced in this paper. The hardware structure, software design and the development of the driver under arm-linux system are presented. The CPU is EP9302, and MAX1305ECM is the analog-digital transformer, MAlll is used as the wireless USB adapter to transfer the electrical parameters, such as current, voltage, watt and so on. Finally, use this system on an air-conditioner.
