A software burning system and burning method for variable frequency drive board

Abstract

The invention discloses a software burning system and a burning method for a variable frequency drive board, and relates to the technical field of software burning for a variable frequency drive board. The invention includes a software burning circuit board, a code scanning device and a connector; the software burning circuit board includes a battery unit, a code scanning unit, an MCU unit, N storage units, an indicator light unit, a variable frequency drive board MCU model selection button unit, Software programming on / off control button unit and software programming output port. The code scanning device of the present invention scans the barcode on the frequency conversion compressor to obtain the model information of the frequency conversion compressor, selects the model of the MCU of the frequency conversion drive board through the MCU model selection button of the frequency conversion drive board, and writes the frequency conversion drive software in the storage unit into the frequency conversion of the refrigerator through the connector The drive board drives the MCU; when the refrigerator variable frequency drive board is put into the warehouse, the variable frequency drive software can be programmed on the assembly line, which improves the versatility of the variable frequency drive board and greatly reduces the problem of numerous material code states when entering the warehouse.

Description

technical field [0001] The invention belongs to the technical field of variable frequency drive board software burning, and in particular relates to a variable frequency drive board software burning system and a burning method. Background technique [0002] At present, with the implementation of the new national standard energy efficiency standards for domestic refrigerators, inverter refrigerators have been fully popularized. Because inverter refrigerators use inverter compressors, inverter compressors include BLDC (Brushless DC Motor) or PMSM (Permanent Magnet Synchronous Motor), in order to In order to control the operation of the inverter compressor to different speeds, the refrigerator must also be equipped with a inverter drive board for the inverter compressor, which is used to control the operation of the inverter compressor motor. [0003] The parameters of the compressor motor of different inverter compressor manufacturers are not the same, and even the inverter co...

AI Technical Summary

Problems solved by technology

[0006] (1) Since the complete machine manufacturer needs to purchase different types of variable frequency drive boards, the codes of the materials for the variable frequency drive boards entering the warehouse are numerous, which is not conducive to the generalization of materials, and also increases the cost of procurement management;

[0007] (2) The operators of the production line should identify and install the corresponding variable frequency drive boards one by one. It is very easy to install wrongly and cause the quality risk of not being able to drive the variable frequency compressor normally;

[0008] (3) For refrigerator after-sales service personnel, if the inverter compressor in the user's home is damaged and needs to be replaced, they must also apply for the corresponding inverter drive board materials, which greatly increases the cost and difficulty of after-sales maintenance
