Problems solved by technology

Due to the large number of multi-connected unit node devices, the data transmission volume is relatively large. At this time, the traditional electricity meter protocol can no longer meet the data transmission requirements of the multi-connected group. A New Protocol of Power Line Carrier Communication Network for On-line Air Conditioning Units

Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] see figure 1 , in one embodiment, a multi-connection method for an air conditioner based on a power line carrier communication network, comprising the following steps:

[0035] a) The system is powered on;

[0036] b) The master sends a synchronous data frame to make all slaves enter the communication mode;

[0037] c) The host sends device control data to control all slaves;

[0038] d) The host and the slave communicate status data within a preset communication time;

[0039] e) the host stops communicating with the slave; and

[0040] f) The host judges whether the bus is idle, and i...

Abstract

The invention relates to an air conditioner multi-split method based on a power line carrier communication network. The multi-split method comprises the following steps that a host computer transmits a synchronous data frame to make all subordinate computers enter the communication mode; the host computer transmits equipment control data to all the subordinate computers to conduct control; the host computer conducts state data communication with all the subordinate computers within the preset communication time value; the host computer stops communication with all the subordinate computers; and the host computer judges whether a bus is available or not, and if yes, the mentioned steps are implemented in sequence once again. By means of the air conditioner multi-split method, the communication requirement of a multi-split air conditioning unit can be met.

Description

technical field [0001] The invention relates to an air conditioner protocol, in particular to an air conditioner multi-connection method based on a power line carrier communication network. Background technique [0002] In the same communication network, the data transmission and interaction between various devices are carried out in the form of protocols, so the formulation and application of the protocols often determine the communication efficiency of the communication network. At present, most power companies use power line carrier communication network for power management, which is used for user's meter reading, billing and other functions. Since the meter reading and billing operations in the power line carrier communication network are point-to-point communication between various devices, and because the communication network has fewer node devices and less communication data, the formulation of the meter protocol adopted by the power line carrier communication netwo...
