Networking method for online detection of smart substation sensors based on zigbee network

Abstract

The invention relates to a ZigBee network based intelligent substation sensor online detection networking method. According to the method, a ZigBee star-shaped networking topology structure is adopted in a station layer of the substation equipment; in the station layer, a coordinator node in the ZigBee application layer performs initializing, starting and establishing of the network; a dual-star-shaped networking topology structure is adopted in a spacer layer and a process layer, and the spacer layer and the process layer are established into a layer of new sub network; in the newly-established sub network, the coordinator node receives a control instruction from an upper computer end, and sends the control instruction to each sensor detection node through the ZigBee network; the detection node collects working state data information of equipment according to the instruction and uploads the data to ZigBee coordinators; and the sensors and the coordinators are configured in substation equipment clusters in a distributed manner and connected with TCP / IP Ethernet servers through wire / wireless communication modes. The significant impacts caused by manual detection difficulties, and natural factors such as equipment aging, weather and the like are greatly reduced by the ZigBee network based intelligent substation sensor online detection networking method, so that the method is quite brighter in the application prospects.

Description

technical field [0001] The invention belongs to the technical field of on-line monitoring networking of intelligent substation sensors, and relates to a method for on-line detection and networking of intelligent substation sensors based on a ZigBee network. Background technique [0002] At present, the communication network system of my country's intelligent substation is developing in the direction of standardization such as digitalization of information within the station, networking of communication platforms, and sharing of information technology. structure; while the bay layer and the process layer adopt the double-star networking mode at the same time, so that the communication network of the process layer and the bay layer in the power grid communication system is formed into a new ZigBee control sub-network; then, the ZigBee sensor modules are distributed Transformers (indoor, outdoor), circuit breakers (indoor, outdoor), busbars (indoor, outdoor), capacitors (indoor, ...

AI Technical Summary

Problems solved by technology

On the one hand, the above layered network method has a large network scope, but it is limited by the difficulty of network construction, the large number of wiring, and the coordinator and router in the network must be full-featured equipment; on the other hand, the communication system in the substation In the networking, due to the distribution characteristics of the ZigBee network itself, after the coordinator in the ZigBee network completes the establishment and startup of the network, the operation of the entire network will no longer depend on whether the coordinator exists. At this time, the role of the coordinator will be Like a router, therefore, the role of the coordinator node will conflict with the role of the router node, wasting the resources of routing nodes and some sensor nodes
