Embodiment Construction

[0020] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0021] figure 1 A schematic structural diagram of a pipeline security system with an optical fiber sensor is shown. like figure 1 As shown, the pipeline security system of the optical fiber sensor includes a pipeline 3, an optical cable 4, a detection host 5, a processing host 6 and an integrated monitoring platform 7, wherein the optical fiber is used to "perceive" vibration, sound and other information near the pipeline, and then send it After obtaining the vibration, sound and other information, the information is sent to the detection host; the detection host denoises and filters the signal transmitted by the optical fiber, and converts the analog signal into a digital signal, and then transmits the signal to the processing host to pass Proces...

Abstract

The invention relates to a method for positioning and debugging a pipeline security and protection system based on an optical fiber sensor. The method comprises the step 1 of positioning an optical cable well, the step 2 of positioning an optical cable pile, the step 3 of positioning a pipeline, the step 4 of collecting soil vibration data and dividing the environmental region along the optical cable according to the detected vibration data. According to the method, the environmental region along the tested optical cable can be divided, the conditions of the external field environment and the influence of the geologic characteristics on the system detected signals can be got visually, and the individual parameter configuration efficiency and progress can be effectively improved, and therefore, various intrusion behaviors occurring at later period can be analyzed for different environmental regions conveniently. On the basis, the system is capable of accurately positioning the intrusion behaviors at the later period and the manager can handle the intrusion behaviors conveniently; as a result, the losses can be reduced to a large extent and the management can be performed conveniently.

Description

technical field [0001] The invention relates to the field of distributed optical fiber sensing, in particular to a method for positioning and debugging a pipeline security system based on an optical fiber sensor. Background technique [0002] Optical fiber sensors can be divided into three categories according to their scope of action: point sensors, integral sensors, and distributed sensors. Among them, because distributed optical fiber sensing can monitor the data of each point of optical fiber, its application has been widely valued worldwide, and it has incomparable advantages of other traditional electrical sensors, mainly: electrical insulation, anti-electromagnetic interference, resistance High temperature and high pressure, chemical corrosion resistance, flexible layout and low maintenance cost. At present, distributed optical fiber sensors are mainly used for temperature monitoring and safety monitoring of power cables, traffic tunnels, etc. In recent years, with ...
