Due to above-mentioned advantage, fiber-optic vibration early warning system is especially suitable for applying in the protection that power grid cables external force is destroyed, especially
For cable, the existing communications optical cable with ditch laying can directly utilize or be multiplexed；An optical fiber is added in existing cable,
Can will build up fiber-optic vibration early warning system using the optical fiber in new cabling, fiber-optic vibration early warning system uses a set of equipment
The monitoring device carrying out light signal collection can achieve to the monitoring of whole piece cable run and vibration positioning.
In fiber-optic vibration early warning system building course, in order to coordinate the software design patterns of optical monitoring signal device, accurately distinguish
Not daily vibration and damaging vibration, improve precision to fiber-optic vibration signal detection, reduce the false alarm rate of system, and to building
After one-tenth during system response test, it is required to the environment according to cable installation and optical fiber is carried out vibrate mould from different instruments
Intend test, there is presently no the vibration generating arrangement with similar functions, for the cable laying on ground all using manually striking
The mode hit is simulated；Cable for underground laying needs break ground, make to carry out Knock test after cable exposure, or uses
Instrument taps ground；The cable of underground laying is broken ground, exposed after carry out the method for Knock test, not only waste time and energy, and
Too big with cable actual environment difference it is impossible in true simulating reality cable by external force vibration situation, substantially inadvisable；Use
Instrument taps ground and comes analog vibration source, due to the randomness of magnitude of vibrations and the nonrepeatability that produce it is impossible to qualitative fixed
The acquisition vibration parameters of amount are it is impossible to realize precisely arranging and testing.Especially for the circuit of underground different depth, there is no accurately
Effectively vibration generating arrangement to carry out vibration test and test to it.
