Abstract:

With the increasing development of mobile communication technology, the application of remote control systems is constantly creating values for production and life. For the case where the equipment is placed in more remote locations, the application of remote control systems is capable of reducing costs. In this paper, we develop a land earth-pole of the high-voltage direct current (HVDC) remote control system. In particular, through the mobile phone and Global System for Mobile Communications (GSM) module short message communication, we are able to achieve information transmission in the micro-control unit for the legitimacy of the information passed after the resolution of the current command. After that, a pulse signal is generated in order to control the stepper motor by outputting the required torque to achieve the brake opening and closing.

Key words: global system for mobile communications, remote control, stepping motor
