Abstract

The invention provides an automatic testing system and method for a power management product based on Labview. A test software platform is developed based in the Labview, and the control of the on / off of a relay is achieved through an upper computer, thereby further controlling the on / off of each testing circuit so as to achieve the automatic testing of all test items of the power management product. Moreover, the testing progress and results are displayed through a testing display module, thereby bringing convenience to a user for understanding the testing status of each test item, avoiding repeated testing, and improving the testing precision and efficiency.

Description

technical field [0001] The invention relates to the technical field of industrial automatic testing, in particular to a Labview-based automatic testing system and method for power management products. Background technique [0002] At present, the production line test of power management products for electric vehicles generally uses a bench test, manually placing the board, and performing a step-by-step test according to the items in the technical specification. During the test, some switches and buttons must be manually switched to determine whether the test is correct. , and finally get the result. However, this method has the following shortcomings and deficiencies: 1. Manually testing according to the items in the specification, there may be steps that are missed or in the wrong order; 2. During the test, switches and buttons often appear abnormal after opening, and The testers can’t find out in time; 3. After the test is completed, they can’t confirm whether the test is...
