Abstract

The invention provides an automotive electronic product intelligent test system based on an embedded system and a method of the automotive electronic product intelligent test system. The automotive electronic product intelligent test system comprises an embedded controller (1), a mechanical control logic module (2), an executive mechanical structure (3), automotive electronics to be tested (4), ahigh-definition camera (5), an image preprocessing module (6), input / output control logic module (7) and a core processor (8).According to the automotive electronic product intelligent test system, based on the system, through the fact that the controller simulates a signal sent by an automobile and controls a mechanical structure to simulate a manual operation, the repeatability and timeliness oftest work can be reduced; through the fact that human eye information collection is simulated by a visual technology, the consistency and objectivity of product testing can be improved; and through the fact thattest model is improved by machine learning, the precision of the product testing can be improved and the potential design hazards of products can be identified.

Description

technical field [0001] The invention relates to the technical field of data collection and processing of automotive electronic products, and relates to an intelligent detection system and method for automotive electronic products based on an embedded system. Background technique [0002] With the increase of software function superposition and human-computer interaction of automotive electronic products, manual detection methods can no longer cover all possible application scenarios, reducing the effectiveness of product inspection. At the same time, the complexity of product functions increases, which puts higher requirements on the professional ability and testing methods of testing personnel. Different inspectors may draw different conclusions in the same testing environment, reducing the objectivity of testing results. In addition, the shortened product function iteration cycle shortens the test cycle as well. How to shorten the detection cycle as much as possible and im...
