Urban rail vehicle wiring method based on EPLAN platform

Abstract

The invention discloses an urban rail vehicle wiring method based on an EPLAN platform. The urban rail vehicle wiring method includes disintegrating a general electrical theory drawing of a whole train into different parts of local electrical theory maps by EPLAN software, establishing general drawing theory database and local map wiring database, generating a wire size list file by templates, converting the wire size list file into an excel format wire size list, checking duplicate and deleting to obtain the wire size sequencing list of the integral train and various types of carriage vehicle wire size lists, acquiring various carriage vehicle wire size sequencing lists by importing and exporting the templates, verifying various types of carriage vehicle wire size sequencing lists, correcting different types of carriage vehicle wire size sequencing lists according to respective wire size problem lists and terminal problem lists so as to obtain different types of carriage vehicle wiring files, and wiring for various carriages. Operation efficiency is improved, mistaken wiring and debugging workload are reduced, and materials, time and labor cost are reduced.

Description

technical field [0001] The invention relates to an urban rail vehicle wiring method based on an EPLAN platform, and belongs to the technical field of urban rail vehicle manufacturing. Background technique [0002] The electrical wiring of urban rail vehicles is a very complicated work. The current practice is generally to import the wiring data of the electrical schematic diagram into the electrical aided design software EPLAN, establish a basic wiring database, and generate it through the automatic table generation function of the EPLAN software. Partial 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. Roughly divided into the following steps: [0003] (1) Decompose the general electrical schematic diagram of the whole train into partial electrical schematic diagrams of different parts;...

AI Technical Summary

Problems solved by technology

[0011] (1) Low accuracy

It is prone to missing wires and multi-wire errors, wrong connection points at both ends of wires, and wrong connection points of terminal blocks, which will lead to errors in process documents, which in turn will lead to missing wires and equipment wiring errors in the vehicle production process, and even cause equipment to be burned and wires cannot be added. Increase labor waste and material loss

[0012] (2) The manual checking operation is cumbersome and complicated, time-consuming and labor-intensive, and inefficient

Since there are more than 100,000 pieces of wiring information to be input for the entire train, a large amount of data query and review are required. Manual input for long-term check and comparison is prone to visual fatigue, a large number of error messages and many missing lines. line situation

Especially the operation of Visual Basic language often fails to run due to wrong operation

[0013] (3) The wiring of the whole vehicle is divided into local wiring of different parts such as on-board, off-board, control cabinet, console, etc., involving different departments and manufacturers, and their input operation specifications are different, resulting in inconsistency in the final generated information , which increases the difficulty and workload of the verification work
