Adapter and intelligent control system of variable refrigerant flow air conditioner

Abstract

The invention provides an adapter and an intelligent control system of a variable refrigerant flow air conditioner. The adapter of the variable refrigerant flow air conditioner comprises a home bus system (HBS) coding and decoding circuit, a central processing unit and a RS485 driving circuit, wherein the HBS coding and decoding circuit is used for acquiring a first protocol signal sent by the variable refrigerant flow air conditioner and performing decoding processing; the central processing unit is used for converting a decoded first protocol signal to a second protocol signal and performing analytical processing to obtain operation state data of the air conditioner; the RS485 driving circuit is used for sending the operation state data of the air conditioner to a control terminal which the variable refrigerant flow air conditioner corresponds to; and conversion between the first protocol signal and the second protocol signal is rapidly achieved through the HBS coding and decoding circuit, the central processing unit and the RS485 driving circuit in the adapter of the variable refrigerant flow air conditioner, intelligent control over the variable refrigerant flow air conditioner, incompatible with the control terminal of a second communication protocol, of a first communication protocol is finally achieved through the control terminal of the second communication protocol, and the convenience and practicability of the variable refrigerant flow air conditioner in practical application are improved.

Description

technical field [0001] The invention relates to the technical field of home intelligent control, in particular to an adapter for a multi-connected air conditioner and an intelligent control system for a multi-connected air conditioner.

Problems solved by technology

[0004] However, the current multi-connected air conditioners are mainly Japanese brands, such as Daikin, Hitachi, Mitsubishi, Toshiba and other brands, and the communication methods of the corresponding multi-connected air conditioners all adopt Japan’s unique data communication transmission protocol The terminal equipment corresponding to the home system generally uses the signal of the MODBUS transmission protocol for data communication transmission; because most of the multi-connected air conditioners are not compatible with the transmission protocol of the terminal equipment, the terminal equipment cannot read and identify the multi-connected air conditioner. The signal of the HOMEBUS transmission protocol limits the application of the terminal equipment to the intelligent control of the central air conditioner
