Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] see figure 1 The realization flow chart of the present invention shown, the present invention first decomposes the structure of the LED automobile lamp model, and then constructs the binary tree structure, stores the initial information and the failure data packet of the automobile lamp model, and then traverses the binary tree in a subsequent order, and stores the The initial information of the binary tree is compared with the currently analyzed data to determine whether the current analyzed data is consistent with the initial information, and finally determine the position and type of failure of the sample, and com...

Abstract

The invention discloses a LED automobile lamp failure location detection method based on a binary tree model. First, the structure of the LED lamp model is decomposed, a binary tree structure is constructed, the initial information of the automobile lamp model and the failure data packet are stored, and then the binary tree is sequentially traversed. Compare the initial information stored in the binary tree with the current analysis data to determine whether the current analysis data is consistent with the initial information, and finally determine the failure location and failure type of the sample, and complete the failure location detection. The method of the invention is easy to implement, fast in classification speed and higher in classification accuracy than conventional failure analysis methods, and is applicable to single or combined failure location detection of automobile lamps.

Description

technical field [0001] The invention belongs to the technical field of detection of LED automobile lamps, in particular to a method for detecting failure positions of LED automobile lamps. Background technique [0002] Automobile lighting is a part of automobile products, responsible for the role of automobile lighting and indicator signals. Automotive lighting is an important part of automotive active safety, so the location detection of product failure modes is a prerequisite for new product design. According to literature records, the most prominent problems that cause lamp failure are three failure modes: bulb damage, lamp water ingress and lamp structural strength damage. Faced with a large variety of lighting products, finding a suitable model to study the failure location and failure mode of the product has become an urgent problem to be solved. [0003] At present, for the failure problem of LED automotive lamps, the patent document of Chinese Patent Application No...
