Background technology
The English of Optical Fiber composite overhead Ground Wire is Optical Fiber Composite Overhead Ground Wire, is abbreviated as OPGW, is generally called OPGW optical cable.Due to optical fiber there is anti-electromagnetic interference (EMI), from features such as heavy and lights, it can be arranged on electric power line pole tower top and needn't consider that best frame hangs the problems such as position and electromagnetism corrosion.Thereby OPGW has the also distinguishing feature such as lower of higher reliability, superior mechanical property, cost.Optical fiber is placed in the ground wire of aerial high voltage power line, in order to form the fiber optic communication network on transmission line of electricity, this version has ground wire and the dual-use function of communicating by letter concurrently, as communications optical cable have high, the anti-disaster ability of reliability strong, be difficult for, by advantages such as artificial destruction, long service life, operation and maintenance cost are low, in China's communication of power system trunk transit network, being widely applied in recent years.But, in the design service life time limit of OPGW, once ground wire function or optical fiber communication function are lost, not only stopped serviceable life, the more important thing is and can cause huge loss of outage and impact, go back the safe and stable operation of entail dangers to electrical network.Therefore, OPGW running status is carried out to Real-Time Monitoring, find in time, get rid of hidden danger and seem particularly important.
OPGW aeolian vibration frequency on-line monitoring system major function is the aeolian vibration frequency distribution on the OPGW circuit of tens kilometers of real time on-line monitorings, as occurred, ANOMALOUS VARIATIONS system can instant early warning.
Traditional aeolian vibration monitoring method is at OPGW circuit, to choose important some installation aero-vibration monitoring device to monitor at present, each point all adopts GPRS communication mode that data are sent to user side, and the communication existing under adverse weather condition in the wild, monitoring surface is narrow and stability problem.
Summary of the invention
The object of this invention is to provide a kind of reliably, monitor wide distributed power transmission line OPGW aeolian vibration frequency on-line monitoring system.
For reaching above-mentioned purpose, technical scheme of the present invention is:
