Problems solved by technology

Due to the complex shape of the wire harness, it still mainly relies on manual production, which also increases the probability of errors in the wire harness production process
The prior art wiring harness detection mainly relies on manual detection, so the detection efficiency is low, and the detection accuracy is low

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the present invention is not limited to the following specific embodiments.

[0020] As shown in the figure: a wire harness automatic detection method based on a relationship matrix, which includes the following steps:

[0021] (1) Select a standard wire harness with a completely correct connection relationship, and then number the lines in the wire harness from 1 to N, where N is a natural number greater than 1, and then form a N* The standard relationship matrix of N, in which if there is a connection relationship between the lines, the corresponding row and column positions in the matrix are represented by the number "1", and if there is a non-connection relationship between the lines, the corresponding The position of the row and column is represented by the number "0";

[0022] (2), select the wiring harness to be detected, and number t...

Abstract

The invention relates to a wire harness automatic detection technology in the field of automatic detection, and discloses a method for automatically detecting whether connection relations among lines are correct on the basis of a relation matrix. The technical scheme can be summarized as follows: the connection relations among lines in a standard wire harness and the connection relations among lines in a wire harness to be detected are respectively mapped to a standard relation matrix and a to-be-detected wire harness relation matrix, then differences between the two relation matrixes are compared, if the two are completely the same, it is indicated that the connection relations of the wire harness to be detected and the connection relations of the standard wire harness are completely the same, and otherwise, it is indicated that errors exist in the connection relations among the lines in the wire harness to be detected. The method provided by the invention has the following advantages: the connection errors of the lines in a wire harness to be assembled can be rapidly detected, the detection speed is fast, and positions where the connection errors of the lines of the wire harness to be detected occur can be conveniently detected. The method can be applied to wire harness automatic detection of occasions with existence of numerous wire harnesses, such as automobiles, airplanes and the like.

Description

technical field [0001] The invention relates to the technical field of automatic detection of wire harnesses, in particular to a method for automatic detection of wire harnesses based on a relationship matrix. Background technique [0002] There are a large number of wiring harnesses in automobiles, airplanes and other vehicles, military or industrial large-scale equipment. These wiring harnesses transmit data or control signals, and they play a vital role in the correct operation and safety of these vehicles or large-scale equipment. Therefore, in the manufacturing process of these vehicles or large-scale equipment, it is very necessary for the wire harness factory to test the numbered wire harnesses before the wire harnesses leave the factory, and then determine whether these wire harnesses are consistent with the pre-designed wire harnesses. Similarly, it is also very necessary for automobile, aircraft and other manufacturers to further confirm the correctness of the wiri...
