Below in conjunction with specific embodiment, the present invention is described in detail.
The present invention is by manufacturing the process of pipeline, according to the difference of pipeline applications, at the diverse location of tube wall, imbed single mode ordinary optic fibre, special optical fiber or fiber-optic grating sensor and (according to the physical quantity of wanted sensing and required precision, select the optical fiber that different physical quantitys is different with different required precisions; General single mode fiber is used in temperature sensor and strain; The pipeline of different model is imbedded different types of optical fiber), pipeline is become can sensing and the pipeline that can communicate by letter.
With reference to figure 1, can sensing and the pipe-line system that can communicate by letter, comprise sensing measurement equipment, communications equipment, light wavelength division multiplexing and pipeline; In this pipeline, imbed common or special optical fiber or fiber-optic grating sensor, by sensing measurement equipment, monitor temperature, strain and the crack conditions that Raman effect, brillouin effect and the Rayleigh of light in optical fiber reflects to judge optical fiber, thus the health of monitoring pipeline.In tube wall or tube wall surface imbed general single mode fiber, can accurately locate the position that pipeline break occurs by the Rayleigh reflex of light, by stimulated Brillouin effect and Raman effect, micro-deformation and temperature variation that can measuring channel.Same mistake monitors the temperature of optical fiber and leakage point is located in the variation of stress.Meanwhile, in pipeline of the present invention, ordinary optic fibre also can be used for communication, to meet the communication requirement of front end data acquisition.
Sensing measurement equipment is used for analyzing the minimal stress variation of the optical fiber of imbedding pipeline and the variation of temperature; its principle is to utilize the Brillouin scattering effect of optical signal; be that light is while passing through optical fiber; can there is non clastic collision in the phonon producing because of spontaneous heating campaign in photon and optical fiber, the relative incident light frequency of scattering light frequency can change; And be mainly subject to the impact of temperature and strain with the fiber optic materials characteristic of the frequency dependence of Brillouin's rear orientation light, therefore, the variation of measuring its rear orientation light frequency can be known the optical fiber variation of temperature and stress on the way.Because optical fiber is imbedded pipeline, therefore, the variation of fiber stress and temperature has just reflected the stress of pipeline and the situation of change of temperature, accordingly the health status of measuring channel and pipe leakage situation indirectly.
Light wavelength division multiplexing is the passive device without Power supply, mainly realizes the shunt He He road of different wave length light wave, realizes and uses the optical communication of different wave length and measure and carry out simultaneously.
