Abstract

This invention relates to producing field of air conditioner, and especially relates to the system and method for detecting power supply modular and drive modular of frequency conversion air conditioner in its production process. Detecting system and method provided by this invention uses single-chip as core, and cooperates with exporting circuit of voltage measure signal, back-communication circuit of measure signal, communication circuit, indicator light circuit, control circuit of key-press. According to steps, automatically check and diagnose power supply modular and drive modular of frequency conversion air conditioner. And automatically export checking outcome. The invention can greatly reduce time of product line checking frequency conversion air conditioner, increase production effect. At the same time, this invention can check circuit which can not be checked by human. Further more, it can record trouble information of checked module and serial number of checked module with trouble. This invention is easy to do data analysis of trouble module and statistics product qualification rate. At the same time, the invention is easy to find reason of checked module with trouble.

Description

technical field [0001] The invention relates to the field of air conditioner production, in particular to a system and method for detecting a power supply module and a drive module thereof during the production process of an inverter air conditioner. Background technique [0002] In the production process of inverter air conditioners, it is required to test the power module and its drive module of the outdoor unit. Usually, the tested parts of the power module and its driver module mainly include: power circuit and power chip, driver circuit main control chip and communication circuit, protection circuit, reset circuit and rectifier circuit, etc. [0003] At present, there is no standard for testing the power module and its drive module of the outdoor unit in the prior art, and there is no dedicated testing system and corresponding testing method. Usually, different manufacturers conduct inspections according to their own conditions, and their technical solutions are often ...
