Wireless network node and state update method thereof

Abstract

The invention relates to the field of smart homes, and discloses a wireless network node and a state update method thereof. The state update method of the wireless network node comprises the steps that each node in a wireless network periodically send a state broadcast message with a preset cycle, wherein the state broadcast message at least carries the identification number of the node and the current state information of the node; the node receiving the state broadcast messages records the current state information of other nodes carried in the received state broadcast messages, wherein if each node in the wireless network receives the state broadcast messages of the other nodes when needing to send the state broadcast message, the recorded current state information of other nodes are carried in the sent state broadcast message. According to the state update method of the wireless network node, the nodes in the wireless network can periodically send the state broadcast messages and carry the received current state information of other nodes, and thereby the state of each device node in a smart home system can be automatically updated, and the user experience is enhanced.

Description

technical field [0001] The invention relates to the field of smart home, in particular to a node state updating technology of a wireless network of smart home. Background technique [0002] With the rapid development of mobile smart terminals, household devices are becoming more and more intelligent. The smart home system uses the residential space as a platform to integrate equipment related to home life by using integrated wiring technology, network communication technology, security technology, automatic control technology, audio and video technology, etc., to build efficient residential facilities and family schedules. The management system improves the safety, convenience, comfort and artistry of household equipment, and realizes an environment-friendly and energy-saving living environment. [0003] At present, the control of the smart home devices inside the smart home system adopts the control method of the central controller (or home gateway), that is, the central c...

Problems solved by technology

The inventors of the present invention found that although the wireless Mesh network can be used to obtain the status information of each node in the wireless network, it requires the user to actively initiate an inquiry, which is time-consuming after being continuously forwarded by intermediate nodes until the target node receives it. Long, and can not know the status of multiple target nodes at the same time, the user experience is not good
