为满足测控现场环境复杂、数据采集点分散的远程信息测量与控制系统的需要,设计了一种基于嵌入式ARM-Linux平台及以太网、ZigBee协议的通信网络智能测控系统.采用ZigBee技术组建无线星形自组织网络,实现ARM控制器与各ZigBee智能模块的无线连接.ARM控制器通过以太网与远程监控中心进行通信,从而实现对整个智能测控系统的远程信息采集与控制.测试及实践结果表明,系统成本低、易构建、控制地域广、具有很强的扩展性与通用性,满足经济实用的要求,具有良好的应用前景.%Aim at the actual needs for power systems, the authors presents a multi-CPU based embedded system management, multi-channel and multi-species communication, high-capacity data processing capability of the intelligence DTU hardware platform design. LPC3250 and LPC2468 are worked using the multi-processor architecture to achieve a power system, "four remotes" , External 2-way Ethernet Interface, 6-channel serial communication interface. The structure of the various functional modules, as well as remote control, AC sampling, DC sampling and other key parts of the circuit design schematic are described in detail.
