Abstract
Continuous automatic wire-feeding device is a device that delivers metal wires required for electric explosion spraying to the designated position in vacuum environment, thus replacing manual wire-feeding on the equipment. The control system of the continuous automatic wire-feeding experimental device designed in this paper mainly includes three parts: the main control system, the man-machine interface and the upper computer. The main control system is composed of a single-chip microcomputer c8051f020, which realizes the control of components such as the motor drivers, relays, sensors and etc. outputs the collected signals and communicates with the human-machine interface. The human-machine interface consists of an LCD display and an IO expansion board, which can respond to the operator’s instructions and display the experimental data. The host computer communicates with the main control system, sends commands and receives the feedback information of the main control for analysis and processing. The experimental results show that the device realizes automatic wire-feeding control with high degree of automation, which improves the efficiency and reliability of the electric explosion spraying experimental device.
