Description
Technical field
The present invention relates to electric power facility, especially a kind of buried cable based on power carrier radiation seeks cable method.
Background technology
With the development of urban construction, the power cable in present city often has the construction requirement for needing buried laying, cable
Buried laying needs complete construction drawing to position the path of buried cable trend, determines what is buried when drawing lacks
Power cable path trend is more difficult work, though there is hunting instrument to sell currently on the market, these hunting instrument generally with
Positioning line fault is carried out in audio or magnetic field, and distance of reaction is close, and general power cable has certain embedded underground depth, it is difficult to should
With common hunting instrument the power cable of underground is embedded in find.
Electric power carrier communication technology be in, low-voltage power line as communication media, realize data, voice and image
Etc. the communication of Integrated Services Transmission, but power cable design for 50Hz/60Hz low-losses transmission of electricity, during for communicating, need
1 ~ 30MHz frequency band signals are transmitted, power cable will produce leakage in this frequency range, i.e., part signal power will in the form of an electromagnetic wave
Outwardly radiate, equivalent to the linear antenna of poor efficiency, electromagnetic radiation intensity increases with the enhancing of signal power, due to high frequency
Energy entrained by electric wave is stronger, therefore high-frequency strong electromagnetic radiation has certain soil penetration capacity, when in buried cable
When the high-frequency signal power of upper modulation input is sufficiently strong, electromagnetic radiation caused by buried cable can penetrate soil.
The content of the invention
The present invention proposes that a kind of buried cable based on power carrier radiation seeks cable method, can be by buried cable
Power carrier signal is modulated to find the path of buried cable trend and distribution.
The present invention uses following technical scheme.
A kind of buried cable based on power carrier radiation seeks cable method, for finding and positioning buried cable in underground
Trend, the buried cable, which seeks cable method, includes power carrier radiation appliance and hunting instrument, the power carrier radiation appliance
Built-in power carrier module, the hunting instrument built-in electromagnetic radiation detection modules, when seeking cable, the power carrier radiation dress
Put and be connected with one end of buried cable, by the power line carrier module of inside with predetermined power signal output to buried electricity
Cable, makes buried cable send electromagnetic radiation to the week side of boss, and the hunting instrument becomes through electro-magnetic radiation detection modules measurement electromagnetic radiation
Change to confirm buried cable in the embedded path of underground.
Power line carrier module built in the power carrier radiation appliance, the signal exported when seeking cable to buried cable are
White noise signal.
The white noise signal is high-frequency white noise signal.
The hunting instrument is provided with antenna to receive the electromagnetic radiation that buried cable is sent, and the antenna is that directive property is strong
Plate aerial, Antenna Operation frequency range are high band.
Gps satellite locating module built in the hunting instrument, the gps coordinate of the distributed point for positioning buried cable.
Power line carrier module built in the power carrier radiation appliance, when seeking cable, at regular intervals to burying
The interrupted output signal of ground cable, for the time interval in one second to two seconds, the output power signal of power line carrier module is adjustable.
The present invention on buried cable by inputting powerful high frequency white noise signal, using can caused by buried cable
The electromagnetic radiation of penetrated surface determines the buried path of cable, because the electromagnetic radiation of high frequency possesses preferable penetration capacity, can
The limitation for wearing ground hunting to overcome conventional hunting instrument to be difficult to, significantly facilitates and seeks cable operation to buried cable.
During we are bright, hunting instrument is provided with antenna to receive the electromagnetic radiation that buried cable is sent, and the antenna is sensing
The strong plate aerial of property, Antenna Operation frequency range is high band, because the half-power angle of plate aerial is big compared with small and gain, antenna
Directive property is very strong, and the design allows hunting instrument more easily to confirm pass region of the electromagnetic wave from ground, more clearly
Confirm the embedded coordinate of buried cable.
In the present invention, the power line carrier module built in power carrier radiation appliance, when seeking cable, at regular intervals
To the interrupted output signal of buried cable, the design makes electromagnetic radiation possess discernible signal feature, and this allows seek in cable operation and received
Electromagnetic radiation have clearly that mark is available for identifying, cable easily can be radiated electric wave and environment clutter area by operating personnel
Separate.
