Software Design and Implementation of Training Simulator for Operation and Maintenance of an Electrical Control System

The electrical control system of a certain equipment mainly completes the operation process control of the whole vehicle. It adopts a closed-loop interlocking control method. Its signals are cross-transmitted and the conversion nodes are complicated. In addition, the equipment is often in a field condition with turbulent transportation and the working environment is harsh, which causes a great loss of equipment and greatly affects the quality of teaching and training. In order to effectively solve this problem, this article develops an operation and maintenance training simulator for an electrical control system, using a combination of software and hardware, using industrial personal computer as a platform, using computer technology, automatic testing technology, microelectronics technology, and bus technology, Multimedia technology, computer software development technology, etc., to achieve simulation training for the electrical control system of a certain type of equipment. The operation training part of the system is designed according to the actual operation interface, and the equipment action process and results are demonstrated through the computer monitor (or projector) in the form of animation or equipment demonstration video. The hardware circuit part of the system mainly provides the actual working environment for the tested equipment, applies various excitation signals to the tested equipment, collects its response signals to judge its performance, and provides corresponding results according to the operation process. The system software mainly realizes the operation program control, animation demonstration and data saving functions of the simulated trainer. This article mainly introduces the software design and realization method of the system.
