Air conditioner and communication method, device and equipment for indoor and outdoor units of air conditioner

Abstract

The invention discloses an air conditioner and a communication method, a device and equipment of inside and outside machines of the air conditioner. The equipment comprises a CAN bus; an RS485 bus; a data converter, an outside machine of the air conditioner is connected with the data converter through the CAN bus, an inside machine of the air conditioner is connected with the data converter through the RS485 bus; the data converter is used for converting the RS485 data and the CAN data. By adopting the air conditioner and the communication method, the device and equipment of inside and outside machines of the air conditioner, the problem of low communication efficiency of the inside and outside machines of the air conditioner of prior art can be solved, the communication between the inside and outside machines of the air conditioner is rapid, accurate and efficient, and the inside and outside machines of the air conditioner are compatible on network under the different systems, the matching universality of the inside and outside machines of the air conditioner is enhanced under different networks, and the configuration type selection for the inside and outside machines of the air conditioner is more flexible under different systems.

Description

technical field [0001] The present invention relates to the field of air conditioner control, in particular to an air conditioner and a communication method, device, and equipment for an air conditioner and an internal and external unit of the air conditioner. Background technique [0002] In the multi-connection system, if the RS485 network is fully used for multi-connection, the communication rate is slow, and the anti-interference and data fault tolerance capabilities are weak, and the protocol update is difficult; while the CAN network is completely used for multi-connection, although the communication rate and anti-interference ability are limited. It is greatly improved, but due to the limitation of its own network characteristics, the number of valid data bytes sent per frame is small, so the efficiency of sending data is low. [0003] Specifically, CAN (Control Area Network) is a serial communication that can effectively support distributed real-time control with a v...
