Abstract

The invention discloses an intelligent teaching and checking system for an electrical control experimental training. The intelligent teaching and checking system comprises an experimental training operating platform, a control unit and an upper computer, wherein the control unit is connected with the experimental training operating platform and the upper computer respectively; the control unit comprises an output display module; an experimental training project standard wiring data is preset in the upper computer; the control unit collects the actual wiring data of the experimental training operating platform and compares with the experimental training project standard wiring data, sends comparison result to the upper computer for performing wiring quality checking, and meanwhile sends a corresponding display signal to the output display module according to the comparison result to display the comparison result. The intelligent teaching and checking system for the electrical control experimental training has the advantages of being simple in structure, simple and convenient to operate, and capable of improving teaching efficiency and avoiding device damage.

Description

technical field [0001] The invention mainly relates to the technical field of teaching equipment, in particular to an intelligent teaching and assessment system for electrical control experiments and training. Background technique [0002] At present, electrical control technology is widely used in various automatic control systems. In the majority of colleges and universities and various training institutions, electrical majors generally offer courses related to electrical control technology. Among them, experiments and practical training of typical electrical control circuits are indispensable practical links for courses related to electrical control technology. Therefore, The research and development of supporting experimental equipment for courses related to electrical control technology is particularly important. However, at present, most domestic experiments and training rooms follow the traditional training method, that is, the experimental teacher gives the circuit ...

AI Technical Summary

Problems solved by technology

However, at present, most domestic experiments and training rooms follow the traditional training method, that is, the experimental teacher gives the circuit diagram, and the students select the required devices according to the circuit diagram and connect them with wires, and the students complete the self-test of the connected circuit. After being approved by the teacher, the power was turned on for a test run. Obviously, such a process has great potential safety hazards

Because the students are in the learning stage for the connected circuit, they are not familiar with the theoretical knowledge and circuit structure, so it is difficult to find out the problem when the students conduct self-inspection, and when the teacher checks, because of the time relationship, most of them just check Whether there is a short circuit in the circuit, but it is difficult to check whether some complex circuit pairs are short circuited. The teacher can only judge whether the circuit connected by the students is correct or not based on past experience. One can imagine the dangers of the test run, ranging from equipment damage to personal safety accidents

If the experimental instructor strictly checks the experimental circuit of each experimental platform, it will undoubtedly be a waste of time for some slightly complicated experimental circuits, resulting in some students' experimental circuits not being checked and guided, and the teaching effect is not good

At the same time, since the students are all beginners and the level of wiring technology is low, when the experimental instructors face the experimental circuit like a spider web, they often feel helpless, difficult to sort out the clues, and the teaching efficiency is not high

[0003] To sum up, at present, in the experiments and training links of electrical control technology-related courses, there are generally problems in the correctness and error checking methods of the experimental circuit, manual inspection is unreliable and inefficient, the burden of the experimental teacher's guidance is heavy, and the teaching effect is not good. There are many problems such as the lack of various assessment methods for students' practical effects
