摘要:: 介绍了一种电能预付费系统,主要用于三相动力用户.采用预竹费控制器终端和电能表分离的方式,从原有电表读取相关数据用于比较,在尽量少改动原有接线的情况下安装预付费控制系统.采用安全性和稳定性高的RFID卡,数据存储空间大,实现不开箱操作.控制器终端数据存储采用数据冗余技术,有效降低数据丢失和出错可能性.后台管理系统嵌入有电能质量管理程序,分析从电表读出的相关参数数据,提高供电质量;增设用户信用度管理,实现信用管理.后台管理系统和控制器终端相结合,实现丢卡不丢电,充分保障用户权益.系统可升级,可以增设用户账号,做到一卡多户或者一表多卡.引进开箱记录的防窃电思想,可以实现开箱管理,防止窃电.

Abstract:: A prepaid electric system which is mainly used in the three—phase system is introduced．Based onthe way that the prepaid controller terminals and the power meters are installed separately，reading data fromthe original meter for comparison，we install the prepaid control system with the least alteration of the originalwiring．The use of high security and stability RFID cards which has large data storage capacity ensures that wecan operate it in the case of non—opening electric meter boxes．Terminal control unit uses data redundancytechnology to store datum in order to effectively reduce the possibility of data loss and error．The power qualitymanagement program which is embedded in the background management system analyzes the relevant parame·ter and datum reading out of the power meters，SO as to improve power quality．The combination of backgroundmanagement system and terminal control unit ensure that users will not lose any information even if the card islost．So we will be able to fully secure the rights of users．This system allows of updating and creating new US—er accounts for the purpose of one card with more users or one meter with multi—cards．This paper puts for—ward the idea of box—-opening recorder for anti power—-stealing to reach the goal of box--opening managementand the prevention of power theft．
