The patent discloses an adhesive tape formula fiber sensor based on OTDR optical fiber technique realizes, proves that it has following characteristics with traditional adhesive tape formula fiber sensor based on OTDR optical fiber technique realizes through theory and practice: at present, the optical fiber sensor is applied to the perimeter security industry, and the basic working principle is as follows: the OTDR optical fiber technology utilizes rayleigh scattering and back scattering generated by fresnel reflection when light is transmitted in an optical fiber, and these signals reflect physical events such as vibration, bending, deformation, etc. at various positions along an optical fiber path, and these reflected signals are collected at the transmitting end of the light, and the vibration and position information of these events can be obtained by combining the transmitting time and receiving time of the light. Compared with the traditional security equipment, the OTDR distributed optical fiber vibration security equipment manufactured by using the principle has the advantages of long detection distance, long service life, dense detection points and the like, and is in a popularization stage as a new technology for perimeter security and temperature measurement.
The industry currently uses telecommunication cables to form fiber optic sensors. However, the optical cable used is expensive, and the optical cable reel is very heavy (generally, the weight of 2000m optical cable is 300kg, and the multi-core optical cable is heavier) due to the metal reinforcing structure in the optical cable, so that the optical cable reel is not easy to carry, the cost is high (taking 2000m optical cable as an example, the price is about 4000 yuan), the large perimeter is generally tens of kilometers, and the cost is high. Meanwhile, auxiliary devices such as a rolled band and an iron wire are required to be fixed on the periphery in the construction process, and a large amount of manpower and material resources are required for the construction. The advantages of the security technology cannot be exerted. The sensor used by the technology (OTDR distributed optical fiber vibration security and protection equipment) is an optical fiber, the optical fiber is low in price and light in weight, and is very suitable for popularization, and the currently adopted sensor does not embody the advantages, so that the popularization process of the advanced technology is slow.
The adhesive tape type optical fiber sensor based on the OTDR optical fiber technology has very light weight because of adopting plastics as the supporting material of the sensing optical fiber, and the weight of the sensor is only 30kg, but one tenth of the original weight on the same distance, which is also 2000m sensor. Therefore, the carrying process can be carried manually, and the construction machinery cost is saved. Meanwhile, the structure is simple, the material is cheap, and the cost is only one tenth of the original cost. And the adhesive function of the adhesive tape greatly facilitates the construction process, and the adhesive tape can be directly fixed on the periphery and can be conveniently adhered to the surfaces of media such as enclosing walls, fences, highway guardrails and the like. The operation can be carried out by a single person and a single hand, so that the cost is saved, the construction process is simplified, and the construction progress is accelerated.

The ultraviolet-proof plastic coating can protect the optical cable and simultaneously can keep enough flexibility so as to meet the requirement of laying the vibration optical cable. The high polymer material optical fiber protection tube protects the secondary coated optical fiber and needs to be S-shaped bonded on the network type fiber structure adhesive tape. The diameter of the high polymer material optical fiber protection tube needs to be more than 3 times larger than that of the sensing optical fiber, so that the loose tube vibration optical cable can vibrate when the loose tube vibration optical cable vibrates. The secondary coated optical fiber needs to be loosely placed in a polymer material optical fiber protective tube, and the secondary coated optical fiber can meet the requirement of sufficient tensile strength of the sensing optical fiber. The long-life pressure-sensitive adhesive is used for fixing the sensor on the surface of a measured medium. The ultraviolet-proof plastic coating, the high polymer material optical fiber protection tube, the secondary coated optical fiber, the network type fiber structure adhesive tape and the long-life pressure-sensitive adhesive are of a belt-shaped structure, so that the sensor is convenient to install, the delivery state of the sensor is guaranteed to be of a roll-shaped structure, and the sensor is very convenient to transport and carry. The long-life pressure-sensitive adhesive ensures that the sensor has high viscosity, is easy to peel off, is stable for a long time and is very convenient to mount. And because the sensing optical fiber is supported in a full-coverage manner, the interference of the surrounding environment can be reduced, and the false alarm rate of the system is reduced.
