Abstract

The invention relates to a module offline test system based on LABVIEW, and the system comprises a BMS slave controller which is connected with a module through a collection wire harness, and is used for collecting the data of a battery cell in the module, and transmitting the data of the battery cell to an upper computer main program unit based on LABVIEW; the USBCAN unit is connected with the BMS slave controller through the CANH and the CANL; and the LABVIEW-based upper computer main program unit is connected with the USBCAN unit, performs CAN communication with the BMS slave controller through the USBCAN unit and is used for receiving and analyzing the acquired cell data, and compared with the prior art, the test system has the advantages of improving the test efficiency and accuracy of the whole module and the like.

Description

technical field [0001] The invention relates to the technical field of CAN message analysis, in particular to a LABVIEW-based module off-line testing system and method. Background technique [0002] The existing similar technology is based on the CAN message analysis method of Matlab, which collects the data on the CAN bus of the whole vehicle to track and reproduce the vehicle operation data, analyze the vehicle operation status and the performance test after the PACK goes offline, but does not involve the module Data analysis after offline and before packing. Contents of the invention [0003] The purpose of the present invention is to provide a LABVIEW-based module off-line testing system and method in order to overcome the above-mentioned defects in the prior art. [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005] A module off-line test system based on LABVIEW, used to judge whether the module is normal, ...
