SURVEYING METHOD FOR TOTAL OPTICAL FIBER TYPE TOTAL BRIDGE SAFETY MONITORING MATCHING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide the surveying method of a total optical fiber type total bridge safety monitoring matching system.;SOLUTION: There is provided a total optical fiber type total bridge safety monitoring matching system having a smart phone voice alarm that includes a safety device and an optical fiber surveying device and communication equipment. In a basic structure, a use cable and an optical fiber are joined to each other with two ends by heat-shrinkable sleeves, and a surveying section is positioned between two heat-shrinkable sleeves, and the safety device provides a predetermined tensile force to the surveying section, and the optical fiber surveying device surveys a distortion by the raster of the in-optical fiber surveying section, and when the surveying section receives the distortion, the surveying section changes from a first state to a second state, and signal fluctuation occurs in a reflection signal. A signal processor converts the reflection signal in which the signal fluctuation has occurred into a physical parameter, and transmits an alarm signal via the communication equipment to a user side, and the alarm signal is transmitted to the portable telephone of the user, and a bridge safety state is actively announced by a human language system.;COPYRIGHT: (C)2014,JPO&INPIT
