Description

A kind of distribution fault detection system of two-way wireless communication
Technical field
The distribution fault detection system of a kind of two-way wireless communication of the utility model belongs to Distribution Network Failure detection technique field.
Background technology
Power distribution network directly connects the user, its reliable power supply ability and power supply quality directly affect user's life, therefore the robotization of power distribution network has become an extremely urgent task, more and more obtained everybody attention, power distribution network is because branch is many and complicated, circuit always need to expend a large amount of human and material resources and time if any fault as looking for out of order particular location; The research of localization of fault is more and more, and has shaped article to provide, but most intelligent degree is not high, also needs artificial searching; Also have through GSM at present information is sent it back the backstage, in conjunction with the system of the accurate localization of fault of GIS.But this fault location system is all unidirectional, always when the fault appearance, then the fault detector board turning sends data to receiving front-end, then background process, and the actual conditions of fault detector always can not well be grasped, be easy to meeting because of fault detector fault or electricity shortage, and can not accurately locate.
The utility model content
The utility model overcomes the deficiency that prior art exists, and technical matters to be solved is: a kind of distribution fault pick-up unit that can two-way wireless communication is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of distribution fault detection system of two-way wireless communication, comprise: fault detector, data acquisition unit, backstage front end processor and background host computer, be provided with a plurality of fault detectors on distribution line, distribution line is provided with a plurality of data acquisition units along the line, and above-mentioned backstage front end processor and background host computer are arranged on monitoring center;
Described fault detector is provided with the bi-directional RF module, fault detector relies on twireless radio-frequency communication network and data acquisition unit to carry out two-way communication by the bi-directional RF module, data acquisition unit and backstage front end processor carry out wireless telecommunications by the GSM network, and the backstage front end processor is connected with background host computer.
Described data acquisition unit carries out communication with a plurality of fault detectors simultaneously.
Described twireless radio-frequency communication network using 433M twireless radio-frequency communication network.
the beneficial effect that the utility model compared with prior art has is: the utility model is by arranging the bi-directional RF module on fault detector, can realize the two-way wireless communication with fault detector, can the real time inspection data acquisition unit and the working condition of fault detector in conjunction with the software of background host computer, after breaking down, the power supply of data acquisition unit and fault detector or circuit can send in real time failure message, thereby reach self-diagnostic function, reliability and the security of fault detection system have been improved, whole device, simple for structure, cost is lower, practical.
Description of drawings
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described in detail:
Fig. 1 is electrical block diagram of the present utility model;
In figure: 1 is that fault detector, 2 is that data acquisition unit, 3 is that backstage front end processor, 4 is that background host computer, 5 is the bi-directional RF module.
Embodiment
As shown in Figure 1, the distribution fault detection system of a kind of two-way wireless communication of the utility model, comprise: fault detector 1, data acquisition unit 2, backstage front end processor 3 and background host computer 4, be provided with a plurality of fault detectors 1 on distribution line, distribution line is provided with a plurality of data acquisition units 2 along the line, and above-mentioned backstage front end processor 3 and background host computer 4 are arranged on monitoring center.
Described fault detector 1 is provided with bi-directional RF module 5, fault detector 1 relies on twireless radio-frequency communication network and data acquisition unit 2 to carry out two-way communication by bi-directional RF module 5, data acquisition unit 2 carries out communication with a plurality of fault detectors 1 simultaneously, twireless radio-frequency communication network using 433M twireless radio-frequency communication network, data acquisition unit 2 and backstage front end processor 3 carry out wireless telecommunications by the GSM network, and backstage front end processor 3 is connected with background host computer 4.
Above-mentioned fault detector 1 can be realized the fault of circuit is carried out Real-Time Monitoring, as faults such as single-phase earthing, phase shortage, phase faults, processor in fault detector 1 can arrange bi-directional RF module 5 and be the transmission state, sends the machine ID to data acquisition unit 2 by bi-directional RF module 5; Described bi-directional RF module 5 is in accepting state when flat, the information of bi-directional RF module 5 receive data collector 2 transmissions in real time, data acquisition unit 2 after receiving the warning message that fault detector 1 is sent and self address form new address code, then read real-time clock, by the GSM network, send information to backstage front end processor 3, platform front end processor 3 passes through RS232 communication line background host computer 4 in succession, background host computer 4 can be real-time the transmission querying command, the situation of checking circuit, fault detector.
Above-mentioned background host computer 4 is equipped with malfunction monitoring software, can carry out the network topology computational analysis to the data of monitoring, and the combining geographic information GIS of system carries out the location of trouble spot, the user can and check fault detector 1 and the working condition of data acquisition unit 2 by the real-time control of software, to judge whether reliability service of whole system, after breaking down, the power supply of fault detector 1 and data acquisition unit 2 or circuit can send in real time failure message, thereby reach self-diagnostic function, improved reliability and the security of fault detection system.
