Description

Technical Field

[0001] The present invention relates to the technical field of optical cable fault location, and in particular to a pipeline accompanying optical cable relay test pile and a pipeline accompanying optical cable system. Background Art

[0002] In production operations, communication optical cables are the cornerstone of fiber-optic communications and the red line for pipeline safety protection. Ensuring their integrity is the premise and necessary condition for ensuring smooth communication links and normal information service transmission. When a sudden failure of the pipeline accompanying optical cable occurs, efficiently locating the fault location of the optical cable and quickly restoring communications are of great significance for ensuring the safe and stable operation of the production monitoring system.

[0003] The pipeline-accompanying optical cable is buried underground with the pipeline. When an obvious optical cable fault occurs, such as a geological disaster or a third-party construction, it is often easier to determine the fault location. However, when a hidden fault occurs due to rat gnawing or termite infestation, it becomes more difficult to locate the fault location, and the troubleshooting time is difficult to estimate. Every time a core break or loss point occurs, we can only make a rough judgment based on experience, and conduct excavation and testing section by section, which consumes a lot of manpower, material resources, financial resources and time. At the same time, the optical cable cannot be restored for a long time, which will cause the communication equipment to be out of control, the real-time monitoring means of important production data to fail, and the equipment and facilities to be out of control, which will bury a huge hidden danger for the smooth operation of production facilities.

[0004] The statistical analysis of communication optical cable line failures in the past five years found that the causes of pipeline communication optical cable failures can be divided into five categories: geological disaster damage, third-party construction damage, contractor illegal operations, rodent bites such as rats and ants, and other reasons. Among them, geological disaster damage accounts for 10%, third-party construction damage accounts for 12%, contractor illegal operations damage accounts for 3%, rodent bites such as rats and ants account for 70%, and other reasons account for 5%. It can be seen that the probability of hidden failures is very high, which has caused great trouble to the efficient positioning and troubleshooting of optical cable faults and the rapid recovery of communications.

[0005] At present, the conventional means of locating the fault point of the optical cable is to use OTDR (Optical Time Domain Reflectometer) and optical cable fault location tester to locate the fault point, which has the following three problems. First, although OTDR can accurately measure the fault distance of the optical cable, due to the particularity of the pipeline accompanying optical cable, the optical cable is buried underground. After adding factors such as the splicing box and the reserved cable coil, the distance from the ground is very different, and the optical cable fault point cannot be directly found. Second, the effective test range of the test distance accuracy of the optical cable fault location tester is basically within 40 kilometers. In the process of troubleshooting the long-distance natural gas pipeline accompanying optical cable, it often happens that both ends are not accessible to the shore. The positioning test cannot be completed directly at the ODF (Optical Distribution Frame, optical fiber distribution frame) end, and it is necessary to dig in the middle section to find the splicing box interruption fiber core connection equipment test to complete the positioning. Third, when a fault occurs, a lot of time, manpower, material resources, financial resources and other resources are consumed in the troubleshooting process, which seriously prolongs the communication interruption repair time and fails to achieve the purpose of quickly repairing the optical cable fault. Therefore, the present invention proposes a pipeline accompanying optical cable relay test pile, which is used to solve the technical problems of inaccurate optical cable positioning and untimely communication recovery.
