A method and device for controlling the operation of a multi-connected air-conditioning unit

Abstract

The invention provides a method and device for controlling the operation of a multi-connected air-conditioning unit. The method includes a main control board MCU judging whether the multi-connected air-conditioning unit has passed the authentication; if not, the main control board MCU controls the master encryption chip to encrypt The chip sends identity authentication challenge data; the slave encryption chip generates a signature code based on the public key in the master encryption chip and the public key and private key of the slave encryption chip parsed from the identity authentication challenge data, and combines the signature code with the slave encryption chip The public key of the encryption chip is sent to the master encryption chip; the master encryption chip generates a verification code based on the received public key of the slave encryption chip and the public key and private key of the master encryption chip, compares the signature code and the verification code, and sends the comparison result to MCU of the main control board; the MCU of the main control board determines the authentication result according to the comparison result, controls the operation of the multi-connected air conditioner unit, and writes the authentication result into the storage unit of the main control board.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method and a device for controlling the operation of a multi-connected air conditioner unit. Background technique [0002] Multi-connected air-conditioning units are commonly known as "one-to-many", which refers to an air-conditioning system in which one outdoor unit is connected to two or more indoor units through pipes. It has the advantages of energy saving and reliable operation, and is increasingly widely used in public buildings. Applications. [0003] In order to better manage the equipment of the multi-connected air-conditioning unit, the work of the unit is generally controlled by means of certification in the prior art. A common authentication method is that the manufacturer of the air-conditioning unit generates a password in the form of a two-dimensional code, bar code, etc., and compares the generated password with the password stored in the EEPROM of the...
