地线融冰自动接线装置远程控制系统的安全策略

Security Strategy of Ground Wire Ice-Melting Automatic Wiring Device Remote Control System

远程控制地线融冰自动接线装置可提高输电线路地线的融冰效率,同时也会给输电线路的正常运行带来一定的安全风险。给出了一种新的地线融冰自动接线装置的安装结构图,该装置远程控制系统采用纵向加密的APN专网、操作程序逻辑自锁、电机转动的时间管理等手段进行了安全策略的设计,并对设计内容进行了安全模拟试验。试验结果初步证明了本系统的安全性能,可有效防止非法操作,保障地线融冰自动接线装置和输电线路的安全运行。

The remote control ice-melting automatic connection device can improve the ice-melting efficiency of power transmission lines and solve the problem of decentralization in operation and management,but it also brings some security risks to the normal operation of power transmission lines.The installation structure diagram of a new ground wire ice melting automatic wiring device is given.The remote control system of this device adopts the longitudinally encrypted APN private network,the operation program logic self-locking,the time management of the motor rotation and other means to carry out the security strategy design and conduct safety simulation tests on the design content.The test results prove the safety performance of the system,which can effectively prevent illegal operation and ensure the safe operation of the ground line ice-melting automatic wiring device and transmission line.
