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

Embodiment Construction
[0028] Now in conjunction with accompanying drawing, invention is described further. The electrical wiring inspection method of urban rail vehicles in the embodiment of the present invention first establishes figure 1 Equipotential schematic diagram of the system shown; then based on this schematic diagram a Figure 5 The system potential table shown lists each potential point, the components connected to each potential point and its connection position, and the module to which each component belongs. Then decompose the equipotential schematic diagram of the system into figure 2 The equipotential schematic diagrams of the three modules A, B, and C shown are generated according to the equipotential schematic diagrams of each module image 3 The electrical wiring diagrams of the respective modules are shown. Generated according to the electrical wiring diagram of each module Figure 4 The electrical wiring table of each module shown lists the wiring number in the module and...

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...
