Problems solved by technology

However, these methods are limited by the fact that faults are not easy or not allowed to be set, and faults are easy to expand, or the operating principle and mechanism cannot be highly consistent with the actual electrical equipment, or the increase in the number of fault questions requires a large hardware cost, resulting in training The cost is high, etc. Therefore, they are not suitable as the main tool for training the ability to troubleshoot complex electrical systems

Abstract

The invention discloses a method for simulating troubleshooting training of a complex electrical system. The method comprises the steps of 1, building a database and a three-dimensional model for workload; 2, making each part in the database and the three-dimensional model of the load respond according to operation rules, realizing correlation, and triggering a trouble phenomenon through a trouble database; 3, measuring testing points of each part in the database after the trouble is triggered, so as to obtain the basis for trouble reasoning and judging; 4, reconnecting in case of problem in circuit connection; replacing any part suspected in trouble by the replacing function; 5, restarting, and verifying whether the trouble is resolved according to the operation rules. The method has the advantages that the high fidelity effect is reached on the appearance, operation logic, working principle and voltage characteristics which are basically the same as those of an actual electrical device; in addition, the trouble can be edited, so as to expand the trouble examination questions without limitation.

Description

Technical field [0001] The invention relates to electrical systems, in particular to troubleshooting of electrical systems. Background technique [0002] At present, the training of electrical troubleshooting capabilities is mainly carried out on actual electrical equipment, on the teaching system or by simple question and answer methods. However, these methods are either limited by the fact that the fault is difficult or not allowed to be set up, the fault is easy to expand, or the operating principle and mechanism cannot be highly consistent with the actual electrical equipment, or the increase in the number of fault questions requires a large hardware cost, which leads to training The cost is very high, so they are not suitable as the main tool for the training of complex electrical system troubleshooting capabilities. Summary of the invention [0003] In order to solve the many deficiencies in the existing electrical troubleshooting training methods, the present invention pro...
