Embodiment
A kind of association analysis research of the transmission line wire temperature monitoring based on Mesh Wireless Ad Hoc Networks, feature of the present invention is, obtain data by conductor temperature monitoring terminal and calculate conducting wire sag, by Mesh wireless self-networking return data, and carry out association analysis with transmission line of electricity Geographic Information System.
In Mesh network, a node can not only transmit and reception information, can also serve as router to node forwarding information near it, and along with the increase with possible number of paths that is interconnected of more nodes, total bandwidth also increases greatly.By the monitoring of monitoring terminal to conductor temperature, data are transmitted by MANET.First realize the MESH MANET between wireless WIFI hot spot, use multi-hop access mode.Next is the radio communication mode that 2 conductor temperature monitoring devices and the wireless self-networking of monitoring between main IED (base station) adopt ZigBee, what conductor temperature monitoring device disperseed simultaneously is deployed in around each base station, is finally radio communication between hand-held inspection device and the main IED of monitoring (base station).By MANET, data are finally delivered to transformer station as shown in Figure 1.
Embodiment
In project use the effective communication distance of WIFI all according to 10 kilometers of designs, but in order to ensure signal intensity, in practical application, two relay point spacing distances are the longest is 5 kilometers; On circuit, each data of monitoring point is transmitted respectively to both sides transformer station, and on circuit, any monitoring point sends data to the transformer station nearest apart from it, on arranging, utilizes Mesh technology to carry out many routes and arranges:
A) its optimal path to be preferentially relayed in its 5 kilometer range another relay point farthest
B) sub-optimal path is its 2nd relay point far away of distance in 5 kilometer range, when optimal path breaks down, automatically carries out networking again, is routed to sub-optimal path.
C) set gradually, the relay point nearest apart from it is its poorest routed path.
According to above design, 50 kilometers long are less than, under the project condition of 38 monitoring points, even if the monitoring point of distance transformer station circuit interlude farthest for this project pilot circuit, its signal is relayed in the routed path of both sides transformer station, and its wireless bridging also can not more than 5 layers.Major part monitoring point only needs No. 1 ~ 2 relaying, can complete the transmission of data to transformer station.
