The research and development of automotive switches test system based on LabVIEW

摘要

This article describes the research and development of automatic switch test and control system. It introduces the hardware structure of the test system, designs and builds the signal conditioning circuit. Applying of virtual instrument design software to achieve the purpose of control the system, and acquisition and processing of test data. And take some effective measures to curb the noise interference signals. The experimental results show that the system can fulfill accurately online monitoring for the parameters in the test process. The test results can be used as a standard to determine whether the switch qualified.
