Further, the Fibre Optical Sensor demodulation main frame 7 includes display 8, data acquisition unit 9, signal processor 10, report
Alert device 11, the electric signal that Fibre Optical Sensor demodulation main frame 7 is obtained from transmission cable 6 is collected by data acquisition unit 9 to collect, then
Data processing is carried out by signal processor 10, the situation of tunnel double-lining area distress in concrete is drawn in display 8, while will letter
Breath feeds back to alarm 11, once crack occurs in concrete, will send corresponding warning message.
Operation principle of the present utility model：According to lining cutting area fltting speed, along lining cutting advance of the face direction every one section
Apart from preset one optical fiber for pricking certain length, optical fiber can be made to insert concrete lining area with moving for formwork jumbo, served as a contrast
The optical fiber built in area is arranged using " W " font, increases temperature-measuring range, and then carbon coated optical fiber utilizes optical fiber micro-bending anti-poverty
The crack of tunnel-liner area concrete structure and strain, electric signal is converted optical signals to by optical-electrical converter, then by passing
Lose Fibre Optical Sensor of the cable by electric signal transmission to Control Room and demodulate main frame, so as to the area of monitoring tunnel-liner in real time concrete
The crack of structure.
The beneficial effects of the utility model are：The system is based on optical fiber sensing technology, passes through optical-electrical converter and optical fiber
Sensing and demodulating main frame, extensive crack can be carried out to tunnel double-lining area and is monitored early warning, system safety index is high, stability
