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

Abstract

The invention discloses a control method and device for an air conditioner universal controller and the air conditioner universal controller, and belongs to the field of air conditioner communication.The control method comprises the steps that firstly, the type of a to-be-controlled air conditioner is obtained, then different processing is carried out correspondingly according to the type of a single system or double systems of the to-be-controlled air conditioner to obtain pre-sent data packets, and finally, a host is controlled to sequentially send request frames to slaves according to thepre-sent data packets. According to the scheme, the to-be-sent data frames are processed according to the air conditioner type, so that the problems that communication stagnation is easily caused in the process of sending data frames of the data packets when the double-system air conditioner is controlled, and network data packets contain redundant data when the single-system air conditioner is controlled are solved; different processing is carried out on to-be-sent data of the single system and to-be-sent data of the double systems correspondingly, and therefore communication stagnation can be avoided when the double-system air conditioner is controlled; and meanwhile, communication network efficiency is improved when the single-system air conditioner is controlled, so that communicationtime is shortened.

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...
