Technical field
The utility model relates to the power industry localization of fault, particularly a kind of fault automatic location with information remote transmitting function and load monitor system that is applied in the distribution network system.
Background technology
Electric power line fault indicator is used to indicate the position of breaking down in the circuit, is convenient to the maintenance personal and finds fast the trouble spot, in time fixes a breakdown.Traditional fault detector is installed on the transmission line of electricity, the general on-the-spot demonstration trouble spot that is used for; Development and application along with the communication technology, the digital fault indicator has appearred, and increase communication module at the digital fault indicator, cooperate communication terminal, can be with the master station of line fault information remote transmitting to a distant place, formation has the failure monitoring positioning system of the functions such as remote signalling, remote measurement, remote control, remote regulating, makes the master station in a distant place can monitor the information such as the line fault of whole electrical network, line load.
At present the Distribution Fault Location System of main flow substantially all is by a plurality of digital fault indicators that are used for malfunction monitoring that are installed on the overhead transmission line, and the localization of fault and the fault warning master station three parts that are installed in the responsible data analysis in the communication terminal that is used for data remote on the transmission line of electricity pylon and a distant place form.Wherein fault detector and communication terminal adopt the short-distance wireless communication mode of 433MHZ, transmission range is no more than 100 meters, communication terminal and master station adopt the GPRS mode to communicate by letter, and the line fault information conforms information that fault detector is transmitted etc. is sent to master station.The radio-frequency module of 433MHZ mostly itself does not possess conflict and avoids function, when many fault detectors send data to same communication terminal, have serious data loss problem, therefore every communicating terminal can only communicate with 1 to 2 set of fault indicator in actual use, in system sets up, especially when large density system is set up among a small circle, can need a large amount of communication terminals, because the communication terminal cost is expensive, thereby cause the significantly lifting of system cost.
Summary of the invention
The purpose of this utility model is to set up the cost height for existing Distribution Fault Location System, many the problems such as simultaneously communication data conflict of indicator, provide a kind of cheaply based on the power distribution network digitalized fault positioning system of remote signalling, remote measurement, remote control, remote regulating, and system can high reliability be moved, realization is better monitored distribution line, significantly improves the efficient of processing power distribution network short circuit grounding fault.
The technical solution of the utility model is as follows:
A kind of power distribution network digitalized fault positioning system based on zigbee and GPRS technology, comprise a plurality of fault detectors that are installed on the overhead transmission line, be installed at least one communication terminal on the circuit pylon, and master station, it is characterized in that: described system also comprises a plurality of route terminals, each route terminal is installed on the circuit pylon, and described fault detector, communication terminal, route terminal all have the zigbee wireless communication module; Communicate by letter by the zigbee wireless communication module between described fault detector and the route terminal, described route terminal is each other by the communication of zigbee wireless communication module, communicate by letter by the zigbee wireless communication module between described route terminal and the described communication terminal, communicate by letter by GPRS between described communication terminal and the described master station.
The utility model adopts Zigbee-technology, and fault detector sends to route terminal by the zigbee wireless communication module with information.Route terminal adopts the zigbee wireless communication module to carry out reception and the transmission of data.Zigbee is based on a low-power consumption territory fidonetFido of IEEE802.15.4 standard, is characterized in closely, low complex degree, MANET, low-power consumption, low cost.Because Zigbee-technology has automatic network-building, automatic routing function, failure message is sent to communication terminal by route terminal from the network of group, has realized the data communication between fault detector and the communication terminal.Zigbee-technology has perfect data collision and avoids function, thereby has fundamentally solved the channel confliction problem when many fault detectors transmit data to a communication terminal simultaneously.Based on the route terminal cost of Zigbee-technology far below communication terminal commonly used at present, thereby greatly reduced the quantity that system uses communication terminal, reduced system cost.
