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:: An electric energy prepayment system is introduced, which is mainly used for three-phase power users. The pre-bamboo fee controller terminal and the energy meter are separated by reading relevant data from the original meter for comparison, and the prepaid control system is installed with as little change as possible to the original wiring. Using RFID card with high security and stability, large data storage space, and realizes non-open-the-box operation. The controller terminal data storage adopts data redundancy technology to effectively reduce the possibility of data loss and errors. The background management system is embedded with a power quality management program to analyze the relevant parameter data read from the meter and improve the quality of power supply; Add user credit management to realize credit management. The background management system and the controller terminal are combined to realize the loss of card without losing power, and fully protect the rights and interests of users. The system can be upgraded, and user accounts can be added to achieve one card and multiple households or one table multiple cards. The introduction of anti-theft thinking of unpacking records can realize unpacking management and prevent electricity theft.
