Electric power communication optical cable external-damage-prevention alarm device and method

Abstract

The invention discloses an electric power communication optical cable external-damage-prevention alarm device, and belongs to the field of state grid safety facilities. A solar cell panel is used forcharging a lithium ion battery, the lithium ion battery provides power supply for a circuit board through a power line, and an antenna is used for transmitting an enhanced signal when a wireless transmission signal is weak; the output end of the sensor is connected with a signal processing module, and data monitored by the sensor can be output to the signal processing module for data processing; and the signal transmission module can transmit the signals processed by the signal processing module through a VPN channel and finally gather transmission information to a monitoring platform. According to the invention, troubleshooting and first-aid repair time of optical cable faults is greatly shortened, stable operation of important services such as protection and stability of a power line isensured, and safety risks of a power grid are reduced.

Description

technical field [0001] The invention provides a power communication optical cable anti-breaking alarm device and method, which belong to the field of national grid safety facilities. Background technique [0002] At present, the optical cables carrying communication services in the power system are mostly OPGW and ADSS optical cables. The OPGW optical cable is located above the power line as a composite overhead ground wire. Due to its high hanging point and metal armor protection, the risk of external breakage is small. . And another kind of ADSS optical cable is an all-dielectric self-supporting optical cable, which has the characteristics of high insulation, no induction, thin diameter, etc., and is located under the power line, so the ADSS optical cable is interrupted by large vehicles, harvesters, etc. Situations happen from time to time. Especially when the optical cable carries important services such as protection and security control, if the optical cable is inter...

Problems solved by technology

And another kind of ADSS optical cable is an all-dielectric self-supporting optical cable, which has the characteristics of high insulation, no induction, thin diameter, etc., and is located under the power line, so the ADSS optical cable is interrupted by large vehicles, harvesters, etc. happens from time to time

Especially when the optical cable carries important services such as protection and security control, if the optical cable is interrupted frequently or for a long time, in severe cases, the line will run without protection for a long time, and the consequences will be disastrous

[0003] Therefore, it is urgent to solve the disadvantages of the current ADSS optical cable, such as frequent damage by external force, difficulty in determining the location of the broken cable, and long repair time, so as to realize active monitoring and alarm reporting of key positions such as low hanging point and easy interruption of the optical cable, reduce the failure rate of the optical cable, and shorten the failure of the optical cable. Time, improve the operation stability of the optical cable network
