Abstract

The invention provides a vehicle air conditioner offline detection device and method, and relates to the field of vehicle air conditioner detection. The vehicle air conditioner offline detection device comprises a detection module, wherein the detection module comprises an industrial personal computer and a display screen communicating with the industrial personal computer; a signal acquisition module and a signal indication module are connected with a data communication module; the data communication module is in two-way communication connection with the industrial personal computer, and is in two-way connection with a controlled air conditioner through a communication wire harness; a signal receiving unit, a data processing and analyzing unit and an instruction sending unit are arrangedin the industrial personal computer; the signal receiving unit is used for receiving the data acquired by the signal acquisition module and sending the data to the data processing and analyzing unit;the data processing and analyzing unit is used for comparing and analyzing the received data and feedback data, and sending an analysis result to the instruction sending unit; and the instruction sending unit is used for sending an execution instruction to the signal indication module according to the analysis result. According to the vehicle air conditioner offline detection device and the method, rapid delivery inspection of the vehicle air conditioner can be realized, an error position can be determined, and the detection efficiency of a factory is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle air conditioner detection, in particular to a vehicle air conditioner off-line detection device and method. Background technique [0002] Vehicle air conditioners are usually composed of compressors, evaporating fans, condensing fans, electric heaters, temperature sensors, and air conditioning control modules, and the system structure is relatively complex. The off-line detection needs to process a lot of data. During the detection, it is not only necessary to send control commands to the air conditioner control module, but also to consider the logical relationship between the various units of the air conditioner. [0003] Manually carry out factory inspection of products, usually by connecting the air conditioner controller with the air conditioner, manually testing the functions of the air conditioner item by item, and making a qualified judgment by watching the performance of the air conditione...
