Abstract

The invention discloses a system for identifying a detected product. The detected product is tested by test equipment. The test equipment comprises a power supply module, a control computer, a signal conditioning card and an analog input card. The power supply module supplies power to the control computer, the detected product and the signal conditioning card. The signal conditioning card is connected with the control computer through the analog input card. The control computer tests the detected product through a relay output and isolation digital quantity input board card of a PCI bus and a test card. The test equipment uses a multi-channel DI acquisition module to test each product. The invention further discloses a method for identifying the detected product. According to the method, DI channels are reserved, the species quantity of the identified products are changed according to practical requirements of different periods. Hardware identification is changed to software and hardware synchronous identification, and the species quantity and the reliability of product model identification is substantially improved.

Description

technical field [0001] The invention relates to a system for identifying tested products. [0002] The invention also relates to a method for identifying the product under test, in particular to a method for automatically identifying the model of the product under test, which is used in the universal design of test equipment. Background technique [0003] In the past, in the process of synchronous development of multiple products, it often occurs that the product under test does not match with the test cable, test equipment, and test software. For example: a certain product under test chooses the right test equipment, but chooses the wrong test cable with the same brand of connector or the wrong matching test software; or chooses the right test software, but chooses the wrong test cable or test equipment. In order to avoid this problem, generally different product test cables, test equipment and test software have strong specificity and pertinence, but the actual functions ...
