Structure and Control Principle of a Remote-Control System for Mobile Terminal Electromechanical Equipment Using an Android Platform

Abstract

In this paper, the structure and control principle of the remote-control system of mobile terminal electromechanical equipment equipped with an Android platform was explored. In the remote control of the intelligent system, the requirement for the mobile platform is relatively high. Therefore, a new mobile remote-control system is selected, and it is mainly characterized by using the Android platform as the terminal and wireless communication technology to control remote electromechanical devices; a mathematical model for DC (Direct Current) motor is established, and Matlab simulation is conducted to design PID (Proportional Integral Derivative) of the remotecontrol system; finally, the system output data are submitted to the host computer. If the data are wrong, the mobile terminal is established to perform real-time monitoring of the equipment. The internal components of the remote monitoring system include server, client, device information transmission module and motion control module. Subsequently, the function of the system is elaborated in detail, by connecting the Android mobile intelligent terminal client with remote electromechanical devices. The analysis shows that the design of the control system is reasonable and the Android mobile intelligent terminal successfully receives the video, which can be played smoothly. Besides, it can stably upload the data of various electromechanical devices, and control them anytime and anywhere, solving the problems of the wide distribution of electromechanical devices and difficult monitoring. The system is simple in operation, low in cost, and easy to assemble. In future research, a more efficient DC motor can be selected to improve the efficiency of the control system.
