Abstract
What the present invention relates to that a kind of power cable service life based on screen layer carrier communication monitors realizes method, it is characterised in that comprise the following steps: step S01: choose the iron tower of power transmission line intermediate transit point as radio communication, and arrange a Trunked Radio machine；Step S02: be arranged at by photographic head with described intermediate transit point on the iron tower of power transmission line that cable is connected, for regularly obtaining the picture of described cable；Step S03: be coupled to the screen layer of described cable after being processed by described picture through the first signal coupling circuit；Step S04: provide a secondary signal coupling circuit to obtain the data on cable, and be transmitted to described Trunked Radio machine through wireless network and remote control center communication；Step S05: remote control center judges, by analyzing pictorial information, the situation that cable surface is aging.The present invention can provide foundation for cable maintenance, ready in advance for cable bad and replacing.
Description
Technical field
The present invention relates to a kind of cable monitoring technical field, what particularly a kind of power cable service life based on screen layer carrier communication was monitored realizes method.
Background technology
Existing power cable is all provided in field greatly, erosion due to wind and rain, a lot of cables all can damage after a certain time, if running into atrocious weather, the cable being etched is easier to damage, so not only can affect the power supply in area, and the existence of high pressure easily causes fire or casualties.
Summary of the invention
In view of this, what it is an object of the invention to provide that a kind of power cable service life based on screen layer carrier communication monitors realizes method.
The present invention adopts below scheme to realize: what a kind of power cable service life based on screen layer carrier communication was monitored realizes method, it is characterised in that comprise the following steps:
Step S01: choose the iron tower of power transmission line intermediate transit point as radio communication, and a Trunked Radio machine is set；
Step S02: be arranged at by photographic head with described intermediate transit point on the iron tower of power transmission line that cable is connected, for regularly obtaining the picture of described cable；
Step S03: be coupled to the screen layer of described cable after being processed by described picture through the first signal coupling circuit；
Step S04: provide a secondary signal coupling circuit to obtain the data on cable, and be transmitted to described Trunked Radio machine through wireless network and remote control center communication；
Step S05: remote control center judges, by analyzing pictorial information, the situation that cable surface is aging.
In an embodiment of the present invention, described signal coupling circuit includes a MCU, described MCU and is connected with the screen layer of described cable one end through carrier module, high frequency cable, inductive coupler successively.
In an embodiment of the present invention, regularly obtaining in described step S02 is every other day to obtain once.
The present invention passes through taken at regular intervals cable status picture, then the information that periphery iron tower of power transmission line is sent by cable shielding layer carrier communication is utilized to be analyzed through being wirelessly sent to Zhong Kong center, foundation can be provided for cable maintenance, ready in advance for cable bad and replacing.
