Embodiment Construction

[0034] The present invention will be further described below according to the accompanying drawings.

[0035] Such as figure 1 As shown, the main coordinator 1 starts to establish a ZigBee network 11, the router 3, and the terminal node 4 join the ZigBee network established by the main coordinator. In this ZigBee network, select an ordinary router 2 as the backup coordinator. The main coordinator 1 will regularly broadcast heartbeat packets 5 and 6 when it is working normally, and will broadcast recovery instructions 7 and 8 when recovering from a fault. The terminal node 4 has a sleep mechanism, and every time it wakes up, it will ask the parent node and ask for data 10 from the parent node, and the parent node will reply with data 9 . The backup coordinator 2 and the router 3 respectively make a decision on whether to perform role conversion and restart and re-enter the network according to the conversion logic of the main coordinator and the backup coordinator, and the rou...

Abstract

The invention relates to the technical field of low-bitrate wireless personal area networks, in particular to a ZigBee network coordinator redundancy backup method. According to the ZigBee network coordinator redundancy backup method, a ZigBee network, a main coordinator, a backup coordinator, a router and a terminal node are arranged. The ZigBee network coordinator redundancy backup method is characterized in that one router is selected in the ZigBee network to serve as the backup coordinator, conversion logic of the main coordinator and the backup coordinator is realized, and role conversion between the main coordinator and the backup coordinator is conducted according to the conversion logic; restart and re-access logic of the router and restart and re-access logic of the terminal node are realized, and the router and the terminal node conduct restart and re-access according to respective restart and re-access logic. Compared with the prior art, the ordinary router in the ZigBee network is selected as the backup coordinator, the main coordinator and the backup coordinator both have the double-role function, the mutual conversion logic of the roles of the main coordinator and the backup coordinator is in a wireless communication mode, and therefore the defects of physical connection lines are avoided.

Description

technical field [0001] The invention relates to the technical field of low-speed wireless personal area network, in particular to a ZigBee network coordinator redundancy backup method. Background technique [0002] ZigBee wireless communication technology, which belongs to the field of low-speed wireless personal area network, has the characteristics of low complexity, low cost, low speed, low power consumption, self-organizing network, and automatic network repair, and has ZigBee Home Automation, ZigBee Light Link and other standards Compatible with the industry, it has quickly become a mainstream communication technology in the intelligent control industry. [0003] There are three roles in the ZigBee network: coordinator, router, and terminal node. The role of the coordinator is very important. It is a necessary device in a ZigBee network. The coordinator is responsible for initiating the ZigBee network and expanding it by allowing other nodes to join. ZigBee network, af...
