Embodiment Construction
[0023] Such as figure 1 As shown, the present invention utilizes the same routing optical cable to collect the vibration spectrum big data information method around the power cable, including:
[0024] S1: install the fiber optic vibration sensor host and computer equipment in the monitoring room, and the fiber optic vibration sensor host is connected to the existing power accompanying optical cable;
[0025] S2: When there is a vibration source around the power cable to vibrate, the vibration signal is transmitted to the power accompanying optical cable laid in the same ditch as the power cable, the electric accompanying optical cable is deformed, the phase of the optical path in the electric accompanying optical cable changes and the The vibration signal of the vibration source is converted into an optical signal;
[0026] S3: The host of the fiber optic vibration sensor monitors the optical signal in the power accompanying optical cable and obtains the physical characteris...

The invention discloses a method for collecting vibration spectrum big data information around a power cable by using a same routing optical cable. By using the existing power relay accompanying optical cable as a vibration sensor, the power accompanying optical cable is connected to an optical fiber vibration sensor host. When the power accompanying optical cable is disturbed by the outside, thepower accompanying optical cable deforms due to vibration, phase information of transmission light in the power accompanying optical cable is changed, an optical signal is generated, the optical signal is collected, analyzed and demodulated by the optical fiber vibration sensor host, a disturbance signal is restored, and signal characteristic parameters of various vibration events are collected, analyzed and extracted. By demodulating and restoring the frequency spectrum information of the vibration signals, not only can different vibration source objects be distinguished, but also malicious invasion behaviors such as knocking, treading and damaging electric buried cables and channels and well lid touch can be accurately recognized, and the influence of interference of wind, rain, hail andthe like can be shielded.
Description
technical field [0001] The invention relates to the field of power cable monitoring, in particular to a method for collecting vibration spectrum big data information around the power cable by using the same routing optical cable. Background technique [0002] At present, there is no domestic research on vibration spectrum big data information around power cables, and more is to use optical cables to monitor abnormal typical vibration events around power cables, such as vibration waveform signals, so as to protect the safety of power cables. [0003] However, the environment in which power cables are located is complex and harsh, and various vibration events with potential damage to power cables often occur. How to identify these vibration events and make further decisions in order to take corresponding measures and provide protection. Then it is necessary to collect a series of vibration signal big data around the power cable. [0004] We can use the existing power accompan...
