Control method and device of general air conditioner controller and general air conditioner controller

Abstract

The invention discloses a control method and device for a universal controller of an air conditioner, and the universal controller for an air conditioner, which belongs to the field of air conditioner communication. Perform different processing to obtain the pre-sent data packets, and finally control the master to send request frames to the slaves in turn according to the pre-sent data packets. The solution model of this application processes the data frames to be sent to solve the process of sending data packets and data frames when controlling dual-system air conditioners, which easily leads to communication sluggishness, and the problem that network data packets contain redundant data when controlling single-system air conditioners, respectively. Different processing of the data to be sent by the single system and the dual system can avoid communication sluggishness when controlling the dual-system air conditioner, and at the same time improve communication network efficiency and shorten communication time when controlling the single-system air conditioner.

Description

technical field [0001] The present invention relates to air conditioner communication technology, in particular, to a control method and device for an air conditioner general controller and the air conditioner general controller. Background technique [0002] In the development plan of the new generation of general-purpose controllers, RS-485 bus is used for communication. Generally, a single-layer network topology is selected and the main board of the external machine is used as the master, and the rest, such as the display board and the internal machine, are used as slaves. If the traditional Modbus RTU is used protocol, the network communication is initiated by the main board of the external machine, and sends request frames to the slaves such as the display board, the main board of the internal machine, and the debugging tooling in turn, and each slave responds to the request of the main board of the external machine, and sends a response frame in turn. However, the gene...

Problems solved by technology

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a control method and device for a universal controller of an air conditioner and a universal controller for an air conditioner, so as to solve the problem that the universal controller must be compatible with the control of a single-system air conditioner and a dual-system air conditioner, whether it is to control a single system The air conditioner or the dual-system air conditioner sends a large amount of network data packets. The data frame in the network data packet sent when controlling the dual-system air conditioner is too long, which will easily lead to communication sluggishness, while the network data packet sent when controlling the single-system air conditioner contains redundant Data, communication network efficiency is low, communication time is long
