Accompanying drawing illustrates:
Fig. 1 is the utility model overall system pie graph; Fig. 2 is the communication scheme of fault detector and collector; Fig. 3 is that System's composition of the present utility model is shown in figure.
Below by way of embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Embodiment:
Embodiment: the Distribution Network Failure early warning that the present embodiment is applied based on GIS and positioning system, it comprises:
The data acquisition unit be located at the multiple fault detector on cable or overhead transmission line and be located in power transmission line base station, collector receives the radiofrequency signal of described fault detector transmitting and is converted to GPRS/GSM signal and central station communication, and collector is located in the Electric control case near fault detector;
Described central station is located in monitoring machine room, central station by RS232 serial ports be located at the master station that power distribution network monitors in machine room and be connected, the generalized information system of described master station and electrical network passes through TCP/IP communication;
Also comprise administrator terminal, described administrator terminal receives the information that described central station sends.
Shown in Fig. 2, described collector comprises GPRS module, the modular converter be connected with described GPRS module, the radio frequency transceiving module that is connected with described modular converter, the radio frequency transceiving module of described collector communicates with the radio frequency transceiving module of described fault detector, and the radiofrequency signal that described fault detector is launched is sent to described central station by described GPRS module.
In concrete facility, the utility model system is made up of some monitoring nodes, Surveillance center and communication system.Monitoring node is made up of collector and one or more groups fault detector, is responsible for the collection of the information such as remote signalling, remote measurement and uploads.Surveillance center is made up of the part such as main station system, central station, is responsible for gathering and collects remote signalling, telemetry storing, when there being fault to occur, calling GIS platform Topology service analysis of failure position, and failure message is passed to other business management system by master station.Communication system realizes the communication between each hardware such as fault detector, collector, central station by GPRS, GSM, radiofrequency signal, Internet technology.
Communication system is divided into: based on the information transmission system based on RS232 serial ports between the distance transmission system based on GPRS, GSM etc. between the short range wireless transmission system of radiofrequency signal, collector to central station, central station to master station system between fault detector to collector, and system master station realizes communicating by TCP/IP electric power Intranet with GIS platform and other operation system.
Detection node: each monitoring node is made up of some groups of fault detectors and collector.The empty fault detector of every shelving comprises 3 two-in-one fault detectors of short circuit grounding, often organizes cable line fault indicator and comprises 3 display device for short circuits and an earth-fault indicator.Every fault detector all possesses fault detect, radio communication, battery management function.Fault detector is by dry cell power supply, when circuit normally runs, fault detector is in dormancy holding state, when monitored line failure, fault detector in corresponding phase is according to the address code of oneself and information code emitting radio frequency signal, after collector within the scope of Signal reception receives this signal, by public GSM/GPRS system forwards information.A collector can receive the radiofrequency signal of many group fault detectors simultaneously, and collector maximum coverage range can reach diameter 300 meters.Collector with solar panel or 220V Power supply, can make redundant electrical power with lithium battery.
Surveillance center is made up of parts such as system master station, central stations.Central station is arranged on monitoring machine room, is connected with system master station by RS232 interface, for receiving the information that collector sends, and associated alarm information is sent to administrator terminal with short message mode; System master station is arranged on power distribution network monitoring machine room, after receiving the information of central station terminal transmission, resolving information content, integrated with power network GIS platform, geographic information map is made corresponding display, and send alarming short message breath, simultaneously for other business management system provides relevant data by central station to keeper.
During concrete enforcement, this system is mainly arranged on transformer station's outlet, important branch line and important power equipment place, every bar circuit fills 1 group of (totally 3) monitoring point, to realize remote monitoring and the localization of fault of these points, when malfunctioning node detects fault occurrence condition, namely, to all edge emitting Self address and failure cause, after its week mid-side node receives these data, first check and self whether be also present on same faulty line and there is identical failure cause.If there is same circuit and there is identical failure cause.Namely the address of oneself, and failure cause is added in message queue and again sends, and after collector receives this breath letter, namely this information is sent to Surveillance center by GSM network in the mode of note or GPRS.This information meeting activation monitor center applications program, points out faulty line to keeper, and failure cause.Then the topological analysis function of power network GIS platform trouble spot is called by Surveillance center.In conjunction with the fault detector topological structure on GIS figure, failure judgement point, trouble spot analysis rule is as follows: search from power end, search last out of order fault detector, the service area of this fault detector is (by first fault detector to each branch, do not install the branch of fault detector, whole piece branch is all fault coverage) i.e. faulty line region.To failure message, provide location and emphasis colouring function, with different colors display fault section and associated indicator equipment, inform which section circuit is the concrete fault of user occur on.User uses positioning function, in geographic model information, realizes the location of corresponding failure message on the whole network figure and displaying.
The effect that native system is implemented is as shown in the table:
