Abstract

The invention discloses a testing device and a testing method of an air conditioner control panel for an electric vehicle. The testing device comprises a program input unit, an analog signal input unit, an air conditioner PLC, a control panel output acquisition unit and an air conditioner control unit. According to the testing device of the air conditioner control panel for the electric vehicle, an existing testing facility is improved; and each output of the air conditioner control panel is monitored through simulating an electric vehicle air conditioner working environment and controlling of a controller, thereby testing the air conditioner control panel and realizing function testing on the air conditioner control panel for the electric vehicle. Furthermore the testing device has advantages of simple structure and easy assembling. Testing can be performed on all existing products through changing connecting wires between different assemblies according to real products, thereby realizing high flexibility. After-sale maintenance cost is indirectly reduced and product reliability is improved.

Description

technical field [0001] The invention relates to the technical field of automobile air conditioners, in particular to a detection device and a detection method for a tram air conditioner control board which can simulate the working environment of the tram air conditioner to detect whether the control board can be effectively controlled. Background technique [0002] At present, there is no effective detection method for the air-conditioning control panel used in trams, and most of them rely on visual inspection and simple line continuity test to detect. Existing testing methods cannot effectively test the control capability of the air-conditioning control panel for trams, which may cause frequent problems in the control of the air-conditioning control panel for trams, causing certain troubles to customers during final assembly and deployment. Moreover, the existing detection methods do not input and test the program of the frequency converter and PLC (Programmable Logic Contr...
