摘要
针对生活小区内电能表管理繁琐的问题,设计了嵌入式智能化电能表系统,系统由用户单元和小区数据管理中心组成;用户单元采用嵌入式处理器LPC2129作为核心,设计了一种高精度智能数字式电能表,具有防窃电和过流过压保护功能,介绍了其软硬件设计;小区数据管理中心通过小区内的2.4G无线网络与各用户单元通信进行集中管理,并通过GPRS网络与上一级电力局进行通信,完成下达的各种指令;经实验表明,该电能表具有更高的精度,能够极方便地解决集中居住用户的用电管理问题。
The embedded intelligent energy meter system composed of user unit and data management center in residence was designed in connection with.9 the rigmarole energy meter management. The user unit adopted embedded processor LPC2129 as the core of high precision intelligent digital energy meter designed which had anti tampering and over--voltage and over--current protection, and the software and hardware were introduced. The data management center in residence contacts with user units through 2. 4G wireless network to manage intensively, and communicates with bureau of power to operate various orders. The experiments showed that the energy meter had higher precision, and made the energy management of concentrated resident convenient greatly.
