Electric power carrier communication technology is in utilizing, low-voltage power line is as communication media, realize data, voice communicate with the Integrated Services Transmission such as image, but power cable for 50Hz/60Hz low-loss transmission of electricity and design, during for communicating, 1 ~ 30MHz frequency band signals need be transmitted, generation is leaked in this frequency range by power cable, namely part signal power is by outwardly radiation in the form of an electromagnetic wave, be equivalent to inefficient linear antenna, electromagnetic radiation intensity increases with the enhancing of signal power, energy entrained by high-frequency electric wave is stronger, therefore high-frequency strong electromagnetic radiation has certain soil penetration capacity, when the high-frequency signal power of modulating input on buried cable is enough strong, the electromagnetic radiation that buried cable produces can penetrate soil.
Summary of the invention
The utility model proposes a kind of buried cable based on power carrier radiation and seek cable device, path trend and the distribution of buried cable can be found by modulating power carrier signal on buried cable.
The utility model by the following technical solutions.
Cable device sought by a kind of buried cable based on power carrier radiation, for finding and locating the trend of buried cable in underground, described buried cable is sought cable device and is comprised power carrier radiation appliance and hunting instrument, described power carrier radiation appliance built-in power carrier module, described hunting instrument built-in electromagnetic radiation detection modules, when seeking cable, described power carrier radiation appliance is connected with one end of buried cable, with predetermined power, signal is exported to buried cable by the power line carrier module of inside, buried cable is made to send electromagnetic radiation to all sides, described hunting instrument is measured electromagnetic radiation change through electro-magnetic radiation detection modules and is confirmed that buried cable buries path underground in underground.
The power line carrier module that described power carrier radiation appliance is built-in, the signal exported to buried cable when seeking cable is white noise signal.
Described white noise signal is high-frequency white noise signal.
Described hunting instrument is provided with the electromagnetic radiation that antenna sends to receive buried cable, and described antenna is the plate aerial that directive property is strong, and Antenna Operation frequency range is high band.
The built-in gps satellite locating module of described hunting instrument, for locating the gps coordinate of the distributed points of buried cable.
The power line carrier module that described power carrier radiation appliance is built-in, when seeking cable, intermittently outputs signal to buried cable with fixed time interval, and the described time interval, the output power signal of power line carrier module was adjustable at one second in two seconds.
The utility model by inputting powerful high frequency white noise signal on buried cable, utilize buried cable to produce can the electromagnetic radiation of penetrated surface to determine the buried path of cable, electromagnetic radiation due to high frequency possesses good penetration capacity, the limitation that conventional hunting instrument is difficult to wear ground hunting can be overcome, facilitate significantly and cable operation is sought to buried cable.
During we are bright, hunting instrument is provided with the electromagnetic radiation that antenna sends to receive buried cable, described antenna is the plate aerial that directive property is strong, Antenna Operation frequency range is high band, because the half-power angle of plate aerial is compared with little and gain is large, the directive property of antenna is very strong, this design hunting instrument can more easily be confirmed electromagnetic wave passes region from ground, what more clearly confirm buried cable buries coordinate underground.
In the utility model, the power line carrier module that power carrier radiation appliance is built-in, when seeking cable, intermittently output signal to buried cable with fixed time interval, this design makes electromagnetic radiation possess discernible signal feature, this allow seek the electromagnetic radiation received in cable operation have clear and definite mark can for identify, operating personnel can distinguish cable radiation electric wave and environment clutter easily.
