The method includes: fault positioners are mounted on an optical cable line at intervals, and marking the optical path geographic positions of the fault positioners; visually displaying the route of the optical cable line and the actual geographic positions of the fault positioners, tower connector boxes and towers on a GIS map; using the attenuation of an OTDR photometry signal to accurately obtain the light path distance between an optical cable disconnection point and a machine room; positioning the optical cable disconnection point between two adjacent fault positioners marked by optical path geographic positions; positioning the fault positioners positioning the optical cable disconnection point to actual geographical positions on the GIS map. By the GIS-based positioning method, the optical cable disconnection point can be positioned between the adjacent fault positioners marked by the actual geographic positions, and maintenance staff can maintain the optical cable disconnection point according to the positioned actual geographic positions.
Description
Technical field
The invention belongs to Cable's Fault on-line monitoring field, particularly to accurately determining of research fault points of optical cables physical location
Position and display are analyzed, and are specially Cable's Fault independent positioning method based on GIS.
Background technology
Cable's Fault location there is problems in that (1) currently commonly uses OTDR test optical fibre cables and obtains a plurality of light at present
Fine optical power attenuation curve, then uses computer that a large amount of test data are done signal processing and analyzing, and such mode is deposited
The test data obtained at such problem: OTDR are mingled with much noise, increase the intractability to test data, and this is direct
Cause the abort situation calculated position in optical cable inaccurate.(2) test data are carried out the data that fiber optic cable monitor obtains equal
For text formatting, testing staff determines the actual particular location of Cable's Fault according to the network topology of papery and routing diagram, this
Mode is inconvenient；And non-professional optical cable maintenance personnel typically fail to understand network topology and routing diagram, it is impossible to complete therefore
The location of barrier position, causes overhaul efficiency the lowest.(3) existing GIS map be combined with fiber cable network and unreasonable, make
The actual geographic position obtaining trouble point is more difficult to determine, additionally existing system imperfection.
Summary of the invention
The present invention is to solve the problems referred to above, it is provided that Cable's Fault independent positioning method based on GIS.
The present invention adopts the following technical scheme that realization: Cable's Fault independent positioning method based on GIS, including following
Step:
(1) in lightguide cable link, fault locator, and labelling fault locator, shaft tower connector box and the light path of shaft tower are installed in interval
Geographical position；
(2) lightguide cable link, fault locator, shaft tower connector box and shaft tower data are increased at power grid GIS map, straight in GIS map
See display lightguide cable link trend and fault locator, shaft tower connector box and the actual geographic position of shaft tower, in order to be accurately positioned light
Cable fault generation point；
(3) when optical cable generation open circuit, the decay of optical signal can increase at open circuit suddenly, utilizes the decay of OTDR light signal, accurate
Really obtain the optical cable trip point optical path distance away from machine room；
(4) according to the optical path distance of optical cable trip point, and fault locator and shaft tower connector box light path geographical position are combined, by light
Cable trip point is positioned at between the adjacent fault locator of light path geographical location marker or shaft tower connector box and fault location
Between device；
(5) fault locator or the shaft tower connector box of locating optical cable trip point are navigated to actual geographic position in GIS map, i.e.
Optical cable trip point can be positioned at between the adjacent fault locator of actual geographic position mark or shaft tower connector box and therefore
Between barrier localizer, maintainer just can go maintenance according to the actual geographic position of the optical cable trip point navigated to.
Optical cable is in process of deployment, owing to there is optical cable surplus, and the actual geographic position of shaft tower and shaft tower connector box and light
There is gap in geographical position, road, and optical cable laying distance is the longest, and the gap of the two is the biggest, if thus being only aware of optical cable open circuit
After the optical path distance of point, maintainer more accurate cannot navigate to the actual geographic position of optical cable trip point, therefore the present invention
Optical cable is installed fault locator, GIS map shows its actual geographical position, and increases optical cable at power grid GIS map
The data such as circuit, shaft tower connector box, intuitively show on map, make amateur optical cable maintenance personnel can pass through power grid GIS map
Quickly check the lightguide cable link trend in affiliated jurisdiction, be accurately positioned Cable's Fault generation point.
Detailed description of the invention
Cable's Fault independent positioning method based on GIS, comprises the following steps:
(1) in lightguide cable link, fault locator, and labelling fault locator, shaft tower connector box and the light path of shaft tower are installed in interval
Geographical position；
(2) lightguide cable link, fault locator, shaft tower connector box and shaft tower data are increased at power grid GIS map, straight in GIS map
See display lightguide cable link trend and fault locator, shaft tower connector box and the actual geographic position of shaft tower, in order to be accurately positioned light
Cable fault generation point；
(3) when optical cable generation open circuit, the decay of optical signal can increase at open circuit suddenly, passes through with OTDR (optical time domain reflectometer)
The decay of light signal, accurately obtains the optical cable trip point optical path distance away from machine room；
(4) according to the optical path distance of optical cable trip point, and fault locator and shaft tower connector box light path geographical position are combined, by light
Cable trip point is positioned at between the adjacent fault locator of light path geographical location marker or shaft tower connector box and fault location
Between device；
(5) fault locator or the shaft tower connector box of locating optical cable trip point are navigated to actual geographic position in GIS map, i.e.
Optical cable trip point can be positioned at between the adjacent fault locator of actual geographic position mark or shaft tower connector box and therefore
Between barrier localizer, maintainer just can go maintenance according to the actual geographic position of the optical cable trip point navigated to.
Cable's Fault localizer is the Cable's Fault location realizing stagewise based on fiber-optic grating sensor.Cable's Fault
Localizer uses passive device, directly installs with optical cable fibre core welding, non-maintaining.Utilize the recognizable spy of Cable's Fault localizer
Levy, fault locator carried out online wavelength collection and detection, just can the light path geographical position of locating optical cable fault locator, with
The optical wavelength of fault locator is basis of characterization, solves paper labels, electronic tag can not optical cable media recognition and rapid wear
Problem.The present invention can more accurate locating optical cable fault, increase the overhaul efficiency of maintainer.It addition, by GIS map
Powerful spatial data management and analysis ability, the huge advantage of information visualization be applied to lightguide cable link network resource management with
Aid decision；Graphically in the face of user, make user free from numerous and jumbled CHINA RFTCOM Co Ltd mass data, effectively hide user
Unconcerned information, makes in the maintenance focusing on Internet resources and the decision-making of user.
