Electrical equipment virtual maintenance training system simulation method

Abstract

The invention discloses an electrical equipment virtual maintenance training system simulation method. The method comprises the steps that all the physical electrical elements in electrical equipment are disassembled into functional parts respectively, and a model is established with all the functional parts acting as basic objects; then a network topological diagram is constructed according to the electric network connection relationship among all the functional parts in the model, and an incidence matrix is generated by the network topological diagram; and then voltage of all nodes or resistance of all branches is calculated according to the parameters of the incidence matrix and the model, a maintenance man uses a virtual multimeter to measure voltage or resistance between any two nodes in the model, a fault signal is judged according to the measurement result and electrical equipment virtual maintenance training simulation is realized. Detection judgment of the fault signal is performed by using the multimeter so that simulation of the fault of different combinations of node signals and accurate simulation of current of each branch of the circuit under the normal and fault state and voltage and resistance between any two nodes can be realized, and maintenance skill training of operating personnel can be effectively enhanced.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment maintenance, and in particular relates to a simulation method for a virtual maintenance training system of electrical equipment. Background technique [0002] Ship electrical equipment works under conditions of vibration, high temperature and humidity for a long time, and there will be electrical equipment and system failures, which makes the maintenance of ship electrical equipment happen from time to time. In the actual maintenance process, due to the many types of electrical equipment and the changeable failure problems, the maintenance skills and proficiency of operators who have not been trained in actual equipment maintenance are low, and it is easy to cause misoperation that damages electrical equipment, and operational errors are extremely dangerous. It may lead to a greater degree of failure or even damage to the equipment, so it is necessary to strengthen the training of mai...

Problems solved by technology

The virtual maintenance of complex mechanical equipment in the existing virtual maintenance training system mainly studies problems such as virtual disassembly planning, maintenance process, collision detection, etc., and its system is not suitable for signal detection of electrical equipment; while the virtual maintenance of circuits is mainly for circuit boards. , the detection is based on the measurement port, and the fault setting mainly adopts the method of database search. Since all circuit nodes in the electrical equipment line are measurable, and the circuit status is constantly changing, the database is used to search for different combinations of node signals to realize the fault. Simulation is not complete
