Inspection method for electrical wiring of urban rail vehicles

Abstract

The invention discloses a detection method for electrical wiring of urban rail vehicles, which disassembles a systemic equipotential schematic diagram into a modular equipotential schematic diagram, and then forms a modular electrical wiring diagram and an electrical wiring chart. The modular electrical wiring chart is compounded into a systemic electrical wiring chart, then a systemic schematic chart is compared with the systemic electrical wiring chart, the calculation function of the Excel chart is applied: firstly, the wiring number between two components is checked, if the number is more than 1, then there are repetitive wirings and the repetitive wirings are needed to be disposed; secondly, the relationship between the wiring number L of each schematic point and the component number C is checked that weather the result is L = C to 1 or not, if L and l t ; C to 1, then wirings of the schematic point are omitted, if L & g t ; C to 1, then the wirings of the schematic point are exceeded. After checking, the wirings are needed to be caught up or taken out according to the checking result. The accuracy of the final electrical wiring can be guaranteed effectively and the detection method is easier.

Description

technical field [0001] The invention relates to the technical field of urban rail vehicles, in particular to a method for inspecting electrical wiring of urban rail vehicles. Background technique [0002] The electrical wiring of urban rail vehicles is a very cumbersome work. The general method is to import the wiring data of the electrical schematic diagram into the electrical aided design software EPLAN, establish a basic wiring database, and use the automatic table generation function of the EPLAN software to generate partial wiring data. Wiring form, and then manually check and compare, find out the inconsistency of each part's line number, connection position, and equipment connection point one by one, analyze the cause of the error, and finally confirm the modification. The patent application "Urban Rail Vehicle Wiring Method Based on EPLAN Platform" with the application number of 201510282815.8 proposes a technical solution, which decomposes the general diagram of the...

Problems solved by technology

[0006] 2 Since the process is completed by multiple people, there may be missing items or repeated parts at the interface of the schematic diagram, that is, problems will occur at the interface of each module

[0007] 3 When the complete equipotential schematic diagram of the system in process 1 is changed, the contents of subsequent processes are likely to be out of sync

[0008] 4 Human error is inevitable, even if the designer is careful and careful, he will make mistakes
