摘要： An optical fiber sensor system and method for monitoring a condition of a linear structure such as a pipeline is provided which is capable of providing continuous monitoring in the event of a break in the sensing optical fiber or fibers. The system includes at least one sensing fiber provided along the length of the linear structure, and first and second interrogation and laser pumping sub-systems disposed at opposite ends of the sensing fiber, each of which includes a reflectometer. The reflectometer of the first interrogation and laser pumping sub-system is connected to one end of the sensing fiber. The reflectometer of the second interrogation and laser pumping sub-system is coupled to either (i) an end of a second sensing fiber provided along the length of the linear structure which is opposite from the one end of the first sensing fiber, or (ii) the opposite end of the first sensing fiber. Before any break of the sensing fiber or fibers occurs, each reflectometer redundantly monitors the condition of the linear structure over its entire length. After any such break occurs, each reflectometer will continue to receive signals up to the point of the break from opposite ends of the structure.

摘要： An intrusion detection system for monitoring a premises includes at least one optical cable that houses at least one optical fiber and extends about the premises. Optical time domain reflectometry (OTDR) means is operably coupled to opposite first and second ends of the at least one optical fiber. The OTDR means includes first signal processing circuitry that analyzes the backscatter signal received via the first end of the at least one optical fiber in order to detect an intrusion of the premises, and second signal processing circuitry that analyzes the backscatter signal received via the second end of the at least one optical fiber in order to detect an intrusion of the premises. The redundancy of intrusions decisions made by the first and second signal processing circuitry can be verified. The system preferably further includes means for detecting a break in the at least one fiber, for identifying location of the break, for outputting to a user the location of the break, and for raising an alarm indicating the break.

摘要： A leak detection system and method is provided for a structure having a first barrier to a first fluid and a second barrier to a second fluid, the first barrier and the second barrier defining a space therebetween. The system includes at least one sensor, such as a fiber optic sensor, placed in the space and configured to detect presence of the first fluid or the second fluid in the space due to a fluid leak in the first barrier or the second barrier. The fiber optic sensor may further be configured to measure one or more characteristics of an acoustic emission caused by the leak, and the system and method may be able to estimate the orifice diameter of the fluid leak based on the measured one or more characteristics, and to calculate a leak rate based on the estimated orifice diameter.

摘要： A system and method for identifying and measuring the quantity of leakage from a conduit used in the conveyance of a fluid, such as a hydrocarbon fluid, for example oil, or a gas, such as natural gas. The system includes a measurement device configured to measure a distributed temperature along a length of the conduit. The system further includes a processor configured to calculate a change in volume of the fluid in the conduit for each of a plurality of sections of the length of the conduit based on the distributed temperature. The processor is further configured to calculate a correction factor based on the change in volume of the fluid. The processor is also configured to calculate a corrected mass-balance differential using the correction factor, and compare the corrected mass-balance differential to a predetermined leakage threshold to identify whether a leak exists in the conduit.
