    Abstract: 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.
    Key words: ground wire ice-melting; remote control; vertical encryption authentication; torque limiter; proximity switch
