Multifunctional distributed optical fiber vibration monitoring signal enhanced clamp and monitoring device

Abstract

The invention belongs to the field of optical fiber vibration monitoring enhanced clamps, and particularly relates to a multifunctional distributed optical fiber vibration monitoring signal enhanced clamp and a monitoring device. The multifunctional distributed optical fiber vibration monitoring signal enhanced clamp solves the problem of vibration coupling of a sensing optical cable and a carrierroller, and comprises a carrier roller vibration conduction part and at least one vibration conduction suppression part, the carrier roller vibration conduction part is rigidly connected between a carrier roller bracket vibration point and a sensing optical fiber measurement point and is used for directly transmitting the vibration signal of the carrier roller bracket vibration point to the corresponding measurement point of the sensing optical fiber; and the vibration conduction suppression part is arranged on the carrier roller channel steel and is used for fixing the sensing optical cableso as to suppress vibration interference of the carrier roller channel steel and enhance vibration monitoring signals of the distributed optical fibers.

Description

technical field [0001] The invention belongs to the field of optical fiber vibration monitoring enhanced clamps, in particular to a multifunctional distributed optical fiber vibration monitoring signal enhanced clamp and a monitoring device. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Coal mine belt transportation system is the artery of coal mine safety production, and thousands of rollers are the smallest power unit, and whether their working status is normal or not affects the overall transportation safety efficiency. It is understood that most of the current idlers adopt manual inspection methods, and use subjective judgment methods such as listening and watching for inspection. Taking a typical coal mine with a 3-kilometer belt as an example, there are 1,500 sets of idlers every 2 meters, and the upper belt is 3 1, and 1 for the ...

AI Technical Summary

Problems solved by technology

[0004] The inventors found that there is a problem with the vibration coupling between the sensing optical cable and the idler at present. Only the sensing optical cable is laid along the channel steel or the sensing optical fiber is laid in the roadway environment, because the vibration signal generated by each idler will affect the sensing optical fiber at the same position. Create mutual interference so that the source of the fault cannot be identified from the original signal alone
