The method is widely applied to the Internet of things industry, and the figure of the zigbee intelligent equipment can be seen everywhere in office buildings, districts, public places and families. The intelligent home network has the advantages that the intelligent home is applied to the most extensive application and the market is obviously expanded in recent years, a good routing environment is provided for the intelligent home network due to the characteristics of the zigbee star network, and when more and more intelligent devices are arranged in a home, routing lines are more and more abundant, so that the whole system tends to be stable more and more.
Each set of zigbee intelligent furniture system is provided with a coordinator to manage all nodes, and any equipment needs to go through a series of complete network access processes before communicating with the coordinator to obtain network parameters of the current coordinator. If the devices are operated to access the network together in a conventional manner, network congestion may occur, resulting in data packet loss. While the devices are added one by one through the app, each device may take approximately 30-60 seconds to complete the join without the network being disturbed. The experience is very unfriendly for the front-loading hardcover market, and the equipment of the whole set of intelligent furniture needs to be installed by great manpower, so that the equipment needs to be installed for one day at about 100 points of a family, and the installation labor cost is increased. How to solve the problem that zigbee intelligent furniture meets in the actual project that falls to the ground makes equipment network access faster, and the concern is whether the intelligent home can really walk into the user's family.
