Between prepositive communication computer and main website, carry out the RS232 communication system of communication;

Obtain behind the warning message carrying out the network topology computational analysis, combining with Geographic Information System and carry out localization of fault, and the Surveillance center that directly demonstrates the trouble spot geographical location information, on geographical background, show, notify the related personnel to handle in the mode of short message simultaneously according to system wiring figure.

As further improvement of the utility model, native system also comprises: be installed in the indoor or outdoor circuit, make the asymmetric current source with current signal of obvious characteristic of load current stack on the faulty line.

Distribution line fault monitoring system of the present utility model can detect and occur short trouble, singlephase earth fault in the distribution system, system can also utilize fault detector to detect broken string (antitheft) warning function, the phase shortage disconnection fault of detection line, system can directly demonstrate the trouble spot geographical location information, notifies the related personnel to handle in the mode of short message.

Description of drawings

Fig. 1 is the formation synoptic diagram of distribution line fault monitoring system of the present utility model.

Embodiment

Below in conjunction with Fig. 1 the course of work of distribution line fault monitoring system of the present utility model is described.

Need the position of monitoring that fault detector 1 and information repeater station 2 are installed in the main bifurcation of each circuit of this system or the built on stilts junction of cable etc.When short trouble appears in system, when fault detector 1 detects short-circuit current and flows through, provide warning message (board turning and flashing light), simultaneously by short-distance wireless communication system 6, send actuating signal to information repeater station at a distance of 5~20m.Perhaps when singlephase earth fault takes place in somewhere on the circuit, asymmetric current source 9 makes the load current on the faulty line superpose the current signal with obvious characteristic as the earth fault criterion, flow through faulty line, earth fault and the earth of characteristic current returns asymmetric current source, board turning indication when fault detector detects the signal specific that flows through this circuit, and send wireless messages to corresponding information repeater station 2.Information repeater station 2 and fault detector 1 generally are installed in the bifurcation of circuit, for long backbone, also can suitably install several groups, and a station information repeater station can receive the fault alarm information that 9 different branches phase fault indicators 1 send at most.Information repeater station 2 is after receiving fault alarm information, this information is sent to the prepositive communication computer 4 that is placed on Surveillance center by the long distance communication of GSM system 7, after prepositive communication computer receives the information of sending at the data forwarding station, carry out the rough handling analysis, after the address information preservation, give master station 5 with this information by RS232 communication system 8 simultaneously.After master station 5 obtains these warning messages, carry out the network topology computational analysis according to system wiring figure, combine with Geographic Information System and to carry out localization of fault, can directly demonstrate the trouble spot geographical location information, and on geographical background, show, notify the related personnel to handle in the mode of short message simultaneously.

Because master station 5 is to operate under the windows operating system, the possibility that deadlock is arranged, therefore utilize prepositive communication computer as network topology calculate standby, when master station because of certain reason work when undesired, prepositive communication computer can ownly carry out network topology according to the warning message that receives and calculate, fault section position, place, final location, and notify the related personnel in the mode of short message, prepositive communication computer adopts PC104 and winCE embedded OS, add perfect hardware and software house dog design, therefore it can not crash, and guarantees system's reliability service.

Described fault detector 1 epoxy resin integral embedding can guarantee operate as normal under rugged surroundings.

Described short distance radio communication system 6 adopts zigbee communication.

Described GSM long haul communications systems 7 adopts embedded gsm module.

Gsm module is responsible for receiving the synthetic address sign indicating number of radio alarming information and the formation of self address in the information repeater station, utilizes the gsm cellular network, launches with wireless mode.Gsm module is responsible for receiving the short message that the information repeater station sends in prepositive communication computer, gives master station after decoding.The module transmission frequency is 900MHz, uses the 5V working power, quiescent dissipation 10mA, emissive power 2W.Data are adopted the transparent channel transmission.

Described information repeater station 2 generally is installed near the fault detector 1, it can receive fault and the warning message that fault detector 1 sends, with the information that receives and the address integrated encode of self, form unique synthetic address sign indicating number in the system, these information are sent to prepositive communication computer in the mode of short message.Information repeater station 2 by one can outdoor operation stainless steel casing and control corresponding telecommunication circuit form, a built-in non-maintaining 1AH lead-acid accumulator, the outside non-crystalline silicon solar panel that a 5W is installed of casing, in order to charging a battery, and by day as working power.

Described Surveillance center 3 comprises prepositive communication computer 4 and master station 5.

After prepositive communication computer 4 receives the information of sending at the data forwarding station, carry out the rough handling analysis, after address information is preserved, give master station 5 with this information in the mode of RS232 simultaneously.Prepositive communication computer 4 mainly is to receive fault and the warning message that the data forwarding station sends, and decodes then, and data are handled, and at last data is sent to relevant device.Simultaneously, prepositive communication computer also has the function of network topology, can start the stand-by heat function automatically under the situation that master station lost efficacy, and carries out network topology, orients the trouble spot, and sends to the related personnel in the mode of short message.

The main effect of the software systems of the fault location system of master station 5 is to collect fault and the warning message that communication front end processor 4 transmits, after it is handled, find out abort situation and fault paths by topological analysis and calculating, finally be presented on the geographical background of GIS.

Fault location system is the figure support platform with Geographic Information System GIS, and the core algorithm of system is to adopt component technology to realize that the GIS platform has adopted MapObjects 2.0 assemblies.Except basic GIS function, dwindle and roaming etc. as showing, amplifying, native system can be achieved as follows functions peculiar on the GIS platform: (1) shows fault paths with different colors; (2) fault branch that constantly glimmers is removed until the yardman; (3) with the different incorrect fault detectors of color display action to remind the yardman.
