Abstract

The invention belongs to the field of motor control, and especially relates to an automatic detection method and system of compressor models. According to the invention, offline parameters obtained by means of offline identification and a preset error function [delta][sigma](n) of parameters of compressors of known models are utilized to calculate the error value of each parameter, and the model of the current compressor is judged through the error values, so that the working efficiency is improved, the accuracy is improved, the present situation of after-sale service of air conditioners is effectively improved, and the after-sale maintenance efficiency of the air conditioners is improved.

Description

technical field [0001] The invention belongs to the field of motor control, and in particular relates to an automatic detection method and a detection system of a compressor model. Background technique [0002] Nowadays, with the development of frequency conversion air conditioning technology, there are many models of air conditioner compressors, and the corresponding motor parameters are also different. How to quickly and accurately confirm the model of the compressor for maintenance has become a major problem in the after-sales service of air conditioners. Most of the methods used in today's market are to disassemble the machine and check the nameplate of the compressor, so that after confirming the model of the compressor, select the corresponding motor parameters through the dial switch on the circuit board to adjust. However, this method of disassembling the machine to check the brand name of the compressor is not efficient, and because it is mainly controlled by human...
