Real-time online monitoring system for vibration of communication optical cable

Abstract

The invention discloses a real-time online monitoring system for vibration of a communication optical cable. The system comprises a central processing unit, the central processing unit is in transmission connection with a data collection module through a data transmission module, the input end of the data collection module is electrically connected with the output end of a detection unit through awire, and the input end of the detection unit is electrically connected with the output end of a cable through a wire. The invention relates to the technical field of optical cable vibration sensingmonitoring. The invention discloses a real-time online monitoring system for vibration of a communication optical cable. The output end of a selection module is electrically connected with the input end of a display module through a wire; vibration detection can be performed on multiple positions on the cable so that the detection result is enabled to be more accurate and more comprehensive, corresponding chart information can be selected according to the type of the vibration information, the chart information can be enabled to be displayed to the staff in the form of a chart, and the staff is enabled to more visually understand the situation of the detected information data.

Description

technical field [0001] The invention relates to the technical field of optical cable vibration sensing and monitoring, in particular to a real-time on-line monitoring system for communication optical cable vibration. Background technique [0002] Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. Optical cables It is mainly composed of optical fiber (glass filament as thin as hair), plastic protective sleeve and plastic sheath. The optical cable is mainly used in the construction of communication engineering, and the vibration of the optical cable is that the laser emits DC monochromatic light waves. Direct and reverse coupling into the two-core sensing optical fiber to form a forward and reverse loop Mach-Zehnder interference optical signal. During the use of the...
