Description
Technical field
The present invention relates to technical field of electric power communication, and in particular to a kind of power information physical system multichannel based on wifi
Diameter group-net communication method and system.
Background technology
Power information physical system (cyber physical systems, abbreviation CPS) demand for development is using efficiently applicable
Information and Communication Technology the physical message of each link of power grid is acquired extensively.Compared to wired communication mode, wireless communication exists
Flexible access extends over etc. and to have significant advantage.The monitoring of transmission line of electricity facility, intelligent substation and micro-capacitance sensor, adapted
Electric intelligent construction proposes short-distance wireless communication technology urgent application demand.
Currently, ZigBee of the short-distance wireless communication technology based on IEEE802.15.4 of power state monitoring field application
With the WiFi based on IEEE802.11, two kinds of technologies respectively have feature.Wherein ZigBee has advantage low in energy consumption, but its communication band
Width is relatively low, and WiFi then has the characteristics that communication band is roomy and power consumption is higher.Two kinds of communications are supported to utilize AODV
Protocol realization ad hoc network, ad hoc network can further increase communication power consumption.In AODV, when a node needs connection, then will
A route requests message is broadcasted, other nodes are searched in the routing table, if there is reaching the routing of destination node, are then saved to source
Point feedback, source node selects reliable, hop count minimum a route, and stores information to local routing table for use in the following institute
It needs, if a route lines failure, node can simply select another replacement route lines.If source and destination it
Between generic line be blocked due to wall or multi-path jamming, can be adaptive find a longer but available routing
Circuit.The characteristics of this unique framework makes it possess self-organizing.
Part monitoring data are relatively low for communication bandwidth requirements in power state monitoring field, such as humiture environment prison
It surveys, is suitble to realize the wireless networking of low-power consumption using ZigBee, and some supervise the higher state of communication bandwidth requirements
Survey demand, such as partial discharge monitoring, video monitoring, are suitble to realize wireless networking using WiFi technology.Utilize the networking mode of WiFi
Include mainly ap+station patterns and the mesh network pattern based on AODV, the former is suitble to small range networking, the latter to be suitble to big model
The ad hoc network enclosed.
The deployment of radio node is usually fixed in power state monitoring field, and networking requirements are only a wide range of wireless
Networking does not need to realize ad hoc network, simultaneously, it is contemplated that and the robustness of network should have the characteristics of communication link redundancy backup,
Although WiFi mesh networks based on AODV realize a wide range of, wide bandwidth, path redundancy wireless networking, while but bringing certainly
The extra power consumption of networking.
Therefore, how while ensureing communication bandwidth, networking power consumption is reduced, becomes a technology urgently to be resolved hurrily and asks
Topic.
