Abstract
The invention relates to a hot backup method of coordinators in a Zigbee network. The hot backup method is characterized in that a plurality of coordinators are arranged, and each coordinator has a coordinator work mode and a non-coordinator work mode; after each coordinator is started by a self hardware MAC (Media Access Control) address, an ambient environment is firstly scanned, if the Zigbee network is not found, the coordinator works in the coordinator work mode and establishes the Zigbee network, otherwise, standby coordinators in the non-coordinator work mode are taken to enter the existing Zigbee network; and the standby coordinator sends a data package for maintaining movable connection to a main coordinator at intervals, if the standby coordinator does not receive a response package of the main coordinator, one standby coordinator is selected from all the standby coordinators as the main coordinator according to a predetermined rule, and the selected standby coordinator takes a stored MAC address of the original main coordinator as a self MAC address and switches to the coordinator work mode. According to the hot backup method of the coordinator in the Zigbee network, the smooth seamless switching between the main coordinator and each standby coordinator can be realized.
Description
Technical field
The present invention relates to the hot spare method of telegon in a kind of Zigbee network.
Background technology
In Zigbee network, network is set up in the effect of telegon, and in actual environment, telegon often carries the communication with external network (as IP network).In Zigbee network, router and terminal node have multiple usually; thus redundancy and reliability can be improved by increasing node; but coordinator node can only have one in Zigbee network, therefore usually can encounter telegon fault and cause Zigbee network to set up or cannot communicate with outside.Thus need to increase telegon to improve the reliability of network in Zigbee network, prevent the generation of Single Point of Faliure.Owing to can only there be a telegon in Zigbee network, thus when telegon goes wrong, the telegon that artificial replacement is new usually, can affect promptness and the reliability of network service in replacement process.So in highly reliable communication network, need the hot spare method of Zigbee network telegon, when a telegon lost efficacy, can automatically enable telegon for subsequent use.
Traditional hot spare method needs to connect heartbeat between master coordinator, standby telegon, thus Install and configure more complicated, when there being multiple backup coordinator, this mode becomes and is difficult to realize, and backup coordinator does not participate in other work under normal circumstances, causes the waste of resource.
Summary of the invention
Technical problem to be solved by this invention be for above-mentioned prior art provide a kind of provide multiple backup coordinator, simultaneously multiple backup coordinator also can participate in Zigbee network work when not using as master coordinator and between master coordinator and backup coordinator can smooth and seamless switching telegon Zigbee network in the hot spare method of telegon.
The present invention solves the problems of the technologies described above adopted technical scheme: the hot spare method of telegon in this Zigbee network, is characterized in that:
(1), the foundation of master coordinator and backup coordinator:
Multiple telegon is set, each telegon all has two kinds of mode of operations, first mode of operation is telegon mode of operation, and the second mode of operation is non-coordinator mode of operation, and non-coordinator mode of operation comprises router mode of operation and/or terminal node mode of operation;
After each telegon starts with hardware mac address own, first scanning Zigbee network around, if do not find Zigbee network, this telegon then enters telegon mode of operation and sets up a Zigbee network, otherwise just adds existing Zigbee network with non-coordinator mode of operation; The telegon setting up Zigbee network is called master coordinator, and the telegon adding existing Zigbee network with non-coordinator mode of operation is all called backup coordinator; Backup coordinator adds existing Zigbee network with router or terminal node identity, this is done to utilize Zigbee network effectively to communicate;
Backup coordinator is registered to master coordinator after adding existing Zigbee network, master coordinator sends backup coordinator list and master coordinator MAC Address data to backup coordinator, and backup coordinator stores these data after receiving backup coordinator list and master coordinator MAC Address data;
(2), the switching of master coordinator and backup coordinator:
Backup coordinator sends at set intervals and keeps the packet be flexibly connected to master coordinator, and starts timer; Send it back after master coordinator receives and should wrap, backup coordinator resets timer after receiving response;
The packet that master coordinator is flexibly connected according to the maintenance received dynamically updates backup coordinator list;
If the timer expiry of backup coordinator, then all backup coordinator select a backup coordinator as master coordinator according to established rule, and all the other backup coordinator communicate with new master coordinator; The MAC Address of the former master coordinator that the backup coordinator chosen is preserved using it as oneself MAC Address and be switched to telegon mode of operation, be thus level and smooth and transparent concerning this switching other nodes in Zigbee network;
Selecting an established rule as master coordinator in all backup coordinator is: sort to all backup coordinator, successively preferentially select according to clooating sequence and determine master coordinator, or all backup coordinator determine master coordinator according to the rules of competition, or all backup coordinator hold consultation election to determine master coordinator.
Compared with prior art, the invention has the advantages that:
(1), between master coordinator and backup coordinator achieve hot standby by radio communication and exchanges data, and handoff procedure is smoothly transparent, substantially increases the reliability of Zigbee network;
(2), master coordinator and backup coordinator utilize original Zigbee network to carry out radio communication, improve the reliability of communication and reduce the difficulty of deployment, eliminate the physical connection requirements between master coordinator, backup coordinator, as long as new backup coordinator just can be disposed in the place having Zigbee network to cover, and dispose multiple backup coordinator and also become possibility, multiple backup coordinator uses as router or terminal node in Zigbee network, can not waste resource; And by the Zigbee network that the present invention sets up, there is autonomous feature, thus can in running, dynamically increase and decrease the deployment of backup coordinator and original Zigbee network can not be destroyed;
(3), master coordinator and backup coordinator be global function Zigbee node, possesses the function of telegon, router and terminal node, only need enable or disable partial function, be applicable to the Zigbee node that hardware resource is limited when thus switching;
(4), when backup coordinator serves as router, data retransmission work can be participated in, the reliability of Zigbee network can be improved and expand Zigbee network coverage.
