Automobile electronic test system and test method thereof

Abstract

The invention discloses an automobile electronic TVS (Test and Verification) testing system that has automatic testing as well the analyzing and verifying capability. The system comprises a PXI hardware platform device which is responsible for testing an element to be tested, an information processing device which is used for implementing automatic test and analysis of products, an interface box which is used for introducing signals, a power source system which is responsible for supplying power to the PXI hardware platform device and the element to be tested, a remote database server which is used for storing test data and providing queries to remote test data, and any computer which can be connected to the remote database server through the Internet connection for querying the test data. The system is a hardware and software platform that can realize the double capabilities of automatic testing and manual analyzing and can simultaneously switch quickly among different products. Furthermore, according to the system, the invention provides a corresponding method to product testing by utilizing the system.

Description

Technical field: [0001] The invention relates to a testing instrument for electronic products used in automobiles, in particular to an automotive electronic TVS (Test and Verification) testing system capable of automatic testing and analysis and verification and a testing method thereof. Background technique: [0002] In the automotive electronics industry, in order to ensure the safe operation of automobiles, the quality requirements for products are very strict. For failed products, the source of failure must also be traced to avoid batch errors. However, automotive electronic products are also a relatively complex type of electronic products, with complex functions, numerous product I / Os, and support for various communication protocols such as CAN, LIN, KLINE, FLEXRAY, etc., so testing and analysis are more difficult. However, for the quality or quality departments of the automotive electronics industry, both automatic testing of batch products (such as the first batch o...

AI Technical Summary

Problems solved by technology

The software and hardware are relatively fixed, and it is difficult to realize that one device can handle multiple different products. Even if the product switching can be realized, a lot of changes must be made in the software and hardware, which is time-consuming, laborious and costly.

And the existing test system generally faces the final inspection test or experiment, so it generally only has the ability of automatic testing, but cannot realize the ability of manual analysis of each channel, and cannot adapt to the quality department that needs batch testing such as the first piece and faulty products. analysis requirements

[0004] For example, the German SOMA company PCPG4, the German SEA company ATCP and Agilent's 5400 test systems for automotive electronics, these systems only have automatic testing, no manual analysis, and the development cycle is long, and programming cannot be realized through configuration
