Problems solved by technology

[0002] At present, when the device node (or router) under the ZIGBEE network is damaged and needs to be replaced or repaired, the device node needs to be disconnected from the network first before replacement or repair, otherwise redundant device information will be generated in the coordinator , so that the bound address cannot be used in subsequent new nodes, and if the faulty device is used as a router, it may cause the child nodes of the faulty device to be unavailable
In the network layer of the ZIGBEE protocol stack, there is such an off-network (NLME.LEAVE) primitive that can specify the device to perform a network exit operation. However, in this case, the device basically cannot receive and process data, so the off-network (NLME.LEAVE) primitive behavior is not enough, or it is not possible to let the faulty device back out of the network

Abstract

The invention provides a failure equipment intelligent log-out method based on a ZigBee network. According to the method, a detection response mechanism and an intelligent log-out processing mechanism are added, a father node automatically detects the state of a child node, follow-up behaviors including designated log-out, protection for mistaken deletion and forced deletion are judged according to the state of the child node and an algorithm, and the child node restores detection information according to the detection state or tries to synchronize a preceding-stage node. The method reduces maintenance cost of equipment nodes and can process redundant routing information in the equipment.

Description

technical field [0001] The invention relates to a network exit method for faulty equipment, in particular to an intelligent exit method for faulty equipment based on a ZigBee network. Background technique [0002] At present, when the device node (or router) under the ZIGBEE network is damaged and needs to be replaced or repaired, the device node needs to be disconnected from the network first before replacement or repair, otherwise redundant device information will be generated in the coordinator , so that the bound address cannot be used in the subsequent newly added nodes, and if the faulty device is used as a router, the child nodes of the faulty device may not be available. In the network layer of the ZIGBEE protocol stack, there is such an off-network (NLME.LEAVE) primitive that can specify the device to perform a network exit operation. However, in this case, the device basically cannot receive and process data, so the off-network The behavior of the (NLME.LEAVE) pri...
