Household appliances wireless control method and system

Abstract

The invention discloses a household appliances wireless control method and system for controlling a plurality of household appliances distributed at different positions at home. The method comprises the steps: setting node types and parameters; initializing the network access of the system; maintaining the network access; maintaining the network; controlling a plurality of peripheral control nodes out of the network; and periodically accessing the network and maintaining the network. The system comprises a central coordinator, a plurality of controlled household appliances and a peripheral controller connected with the controlled household appliances, wherein the peripheral controller is divided into a first grade peripheral controller and a second grade peripheral controller according to the signal strength. On the basis of an SMAC (simplified marker and cell) protocol, the network maintenance of the on-line peripheral control nodes and the management of the network access and the network interruption can be timely preformed, and the control of the appliances can be realized within an effective time. The two-grade tree network networking mode adopted by a communication protocol is simple and proper in a networking mode, relatively simple in maintaining and building the network, and is higher in the reliability of the network.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to a home wireless control method and system for controlling home appliances distributed in different positions in the home. Background technique [0002] Smart Home (Smart Home), also known as smart house, uses advanced computers, embedded systems and network communication technologies to connect various devices such as lighting systems, environmental control, security systems, and network appliances in the home through a home network. . On the one hand, smart home will allow users to have more convenient means to manage home devices, for example, control home devices through wireless remote control, telephone, Internet or voice recognition, and can also perform scene operations to make multiple devices form linkage; On the one hand, various devices in the smart home can communicate with each other, and can interact and operate according to different states without use...

AI Technical Summary

Problems solved by technology

[0006] 1. It is impossible to detect in real time whether the peripheral nodes are working on the network or not;

[0007] 2. The configuration of network access must be performed before the normal communication state to work;

[0008] 3. Most of the existing control protocols are packaged by foreign companies, which cannot fully meet the actual application requirements and are inconvenient to modify
