Reliably, it is easy to long-distance transmissions；Zero point stability, can long term monitoring；Cheap, output frequency signal collection is simple.Another
Aspect, it has much room for improvement in terms of precision and stability, electromagnetic interference and ambient temperature, choosing of exciting mode and the time of measurement
Etc. all can affect certainty of measurement, and the weak output signal that sensor produces, be difficult to pickup.
Fiber-optic grating sensor due to plurality of advantages such as size are little, the linearity is excellent, reproducible, non magnetic, corrosion-resistant,
Favor is enjoyed in the monitoring field of civil engineering structure.But, owing to the validity period of general structure is longer, the most important knot
Structure, all even goes up a century as the validity period in bridge, tunnel etc., and then requires that the optical fiber of embedment must assure that it in decades
Stablizing with reliable within structure effect duration.The main component of optical fiber is SiO2, is vulnerable to corrosion under the highly basic effect of cement；
Additionally, embedment technological requirement is high and Fibre Optical Sensor deformability is limited.
Above-mentioned all types of pressure transducer all has a common drawback: i.e. easily being disturbed by extraneous factor, certainty of measurement has
Treat to improve further, it is often more important that service life falls short of.For needing disposable in most of civil engineerings monitoring field
Embedment pressure/strain transducer for, service life and later maintenance are required to higher.
In order to solve the problems referred to above, research and develop new length in service life, be susceptible to high new of external environmental interference, certainty of measurement
Type sensor becomes needs objectively.
Utility model content
