Engineering design method of rail vehicle electrical wiring

Abstract

A railway vehicle electrical wiring engineered design method includes the following steps of determining vehicle electrical wiring foundation information and setting up a foundation wiring database according to design information, determining electric wire feeding process data foundation information through the line style, wiring points at the two ends and a cable route, defining electric wiring information with wiring harnesses and the cable route serving as the leading factors according to the process requirement, setting an electric wiring process method with the line type and the wiring points at the two ends serving as the foundations, determining the circuit connection relation with the wire size and the wiring points at the two ends serving as the foundations, and completing the whole railway vehicle electrical wiring engineered design on the basis of the implementation of electric wire feeding, electrical wiring, electrical wire connection and circuit connection. The railway vehicle electrical wiring engineered design method has the advantages that for the characteristics of a railway vehicle electrical circuit, the process design method of railway vehicle electrical wiring is set, the construction process design standard is planned, and the whole work is streamlined, standardize and engineered, accuracy of electric wiring and construction is effectively ensured, and achievement of the functions of an electrical system and reliability and safety of the electrical system are ensured.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle wiring, and in particular relates to an engineering design method for rail vehicle electrical wiring. Background technique [0002] In the past, the electrical system and electrical construction work of railway passenger cars were relatively simple. On the one hand, the design drawing was used as the wiring of the existing car, the wiring was used as the source of information for the process design operation, and the wire blanking table was used as the construction basis. Information processing and production operations were all done manually. Mainly, the error rate is high, and the production efficiency and operation quality are low. On the other hand, there are the following problems in terms of process design methods: 1) There are only simple framework construction requirements for wiring operations, and the chart form and content of wire blanking operations are not uniform, there is no sy...

[0002] In the past, the electrical system and electrical construction work of railway passenger cars were relatively simple. On the one hand, the design drawing was used as the wiring of the existing car, the wiring was used as the source of information for the process design operation, and the wire blanking table was used as the construction basis. Information processing and production operations were all done manually. Mainly, the error rate is high, the production efficiency and operation quality are low

On the other hand, there are the following problems in the process design method: 1) There are only simple framework construction requirements for the wiring operation, the form and content of the wire blanking operation chart are not uniform, there is no systematic process design method, and there is no unified standard; 2 ) The wiring workload of the existing vehicle is heavy, the construction is difficult and the operation time is long; 3) The division and clustering rules of the wiring harness are not obvious, and it is difficult to form an engineering ground pre-assembly operation; 4) There is no application of electrical raw materials such as wires and cables, terminals, etc. effective control and management of
