1.引言电力系统末端的配电网中设置有数目众多的计量柜、电表箱,据统计,95%以上的窃电行为都是通过非法开启计量柜或电表箱后实施的,为防止此类窃电案件的发生,需要对分散的计量柜、电表箱进行统一管理和实时监控。针对上述窃电行为,电力部门采取了许多防窃电手段,如采用机械钥匙、感应式IC卡、按键式电子密码锁、红外射频钥匙加铅封等方式。上述防窃电手段均存在着或多或少的弊端,机械钥匙极易复制且门锁易撬,安全性低;感应式IC卡使用寿命有限,一旦卡内芯片损坏,其内部信息并不容易恢复,而且IC卡身份信息及信息内容复制;按键式电子密码锁价格相对昂贵,且长期使用
1. INTRODUCTION There are a large number of metering cabinets and meter boxes in the power distribution network at the end of the power system. According to statistics, more than 95% of the acts of stealing electricity are implemented after illegally opening the metering cabinet or meter box. To prevent such The occurrence of theft cases requires the unified management and real-time monitoring of decentralized metering cabinets and meter boxes. In response to the stealing behavior, the power sector has taken many anti-theft measures, such as the use of mechanical keys, inductive IC card, push-button electronic password lock, infrared radio keys and seals and other means. The anti-tampering means there are more or less disadvantages, the mechanical keys easily copy and easy pry locks, low security; inductive IC card life is limited, once the card chip damage, its internal information is not easy Recovery, and IC card identity information and information content copy; key-type electronic password lock is relatively expensive, and long-term use
