Abstract

The invention relates to an equipment for teaching electrical engineering used in professional skill and technique training, especially relates to a system for setting fault of electronic control circuit of machine tool and checking and evaluating result of training. The system is composed of a checking and evaluating host and multiple connected terminals for providing training. The host is a PC and its built-in software. The terminal consists of checking and evaluating panel for training operation as well as lower end computer with response function. The invented system possesses multi-functions of setting fault, demonstrating, training, responding, monitoring and managing.

Description

technical field [0001] The invention relates to an electrician teaching device for vocational skill and technical training, in particular to an intelligent machine tool electric control circuit fault setting and training evaluation system. Background technique [0002] At present, the most advanced and representative teaching aid for machine tool electrical control circuit knowledge and fault judgment and handling skills training widely used in vocational education systems is ZL99205421.4 "Machine Electrical O Circuit Fault Demonstration Instrument". It is just a single simulation device of the electrical control circuit of the machine tool assembled by electrical components, with many manual switches and indicator lights correspondingly setting and displaying different faults. Due to the limitation of its structural configuration, this kind of device constitutes a single display, has few functions, is cumbersome and time-consuming to operate, and has many mistakes. It canno...
