Oil and gas pipelines are important pillars of economic development. During and after the installation of oil and gas pipelines, there may be third-party construction operations in the installation area, which could potentially damage the pipelines. Ar hyn o bryd, in order to prevent third-party construction operations in oil and gas pipeline laying areas from damaging oil and gas pipelines, fiber optic vibration detection technology is used for early warning, and an alarm is issued when construction vibration occurs near the pipeline.

With the continuous innovation and development of the global economy and science and technology, people’s awareness of security precautions is becoming stronger, and some important areas such as military strongholds, important government agencies, banks, industrial parks, schools, ayyb. have higher requirements for security. Ar hyn o bryd, there are many different types of perimeter security products both domestically and internationally, such as video surveillance perimeter security systems, active infrared perimeter security systems, leaky cable perimeter security systems, and electronic pulse perimeter security systems.

The distributed precise positioning system uses sensing fiber as the sensing unit, which can monitor various vibrations that are directly touched or transmitted to the sensing fiber through load-bearing objects (such as soil cover, wire mesh, fences, ayyb.) in real time and continuously. The collected data is transmitted through optical communication to the backend fiber server for analysis, processing, and intelligent recognition. It is displayed on the PC end, and the vibration alarm software has powerful functions. Relative pulse electronic fences, tension type electronic fences, leakage cable intrusion detection, and infrared radiation intrusion detectors have the characteristics of passive front-end, long detection distance, lightning resistance, anti-interference, and concealed installation according to shape. Currently widely used in civil aviation airports, judicial prisons, petrochemicals, confidential units, rail transit, military industry, border areas and other industries.

By using the principle of fiber optic vibration to monitor abnormal situations in the pipeline corridor, it is possible to achieve long-distance real-time seamless monitoring of soil vibration along the pipeline corridor. Through precise vibration signal analysis, accurate target positioning of damage events can be made; It can achieve comprehensive and real-time online monitoring and real-time alarm of underground comprehensive pipe galleries, greatly improving the rapid response and safety prevention and control capabilities of urban underground comprehensive pipe gallery operation and management;

The management platform is connected to two or more warning subsystems, as well as two or more video surveillance devices, and interconnected through a local area network or the Internet. Remote viewing can be achieved through a mobile app or client; Set up a visualization module in the management platform to achieve visual management of data; The sensing terminal, as the front-end detection part, is completely passive, does not require power supply, and has high-level lightning protection, achieving the effect of low energy consumption and easy maintenance; The connection optical cable and induction optical cable used not only ensure sensitive detection performance, but also have good protection effect, adapting to high temperature and rainy summer and low temperature winter environment, greatly extending the service life; The sensing terminal is installed in the pipe gallery through a fixed frame, allowing it to be suspended. The suspended installation structure can mechanically amplify the vibration of the pipe gallery, which helps the sensing terminal to monitor the vibration of the pipe gallery and greatly improves the monitoring effect of the pipe gallery.

The fiber optic vibration warning system for the pipe gallery includes a management platform, 2 or more warning subsystems, 2 or more video surveillance devices, and alarms; The management platform is connected to the warning subsystem, video surveillance equipment, and alarm respectively.

Each warning subsystem includes a sensing terminal, a sensing initiator, and a fiber optic vibration host; The sensing terminal is connected to the sensing initiator through an induction optical cable, and the fiber optic vibration host is connected to the sensing initiator through a connecting optical cable; The connection optical cable and induction optical cable used not only ensure sensitive detection performance, but also have good protection effect, adapting to high temperature and rainy summer and low temperature winter environment, greatly extending the service life.

The fiber optic vibration host and video surveillance equipment are connected to the management platform through switches.

The outer side of the induction optical cable is equipped with a sleeve, which is a type of stainless steel pipe or PVC pipe. When encountering severe weather, it effectively prevents interference with the induction optical cable, facilitates signal analysis, and effectively reduces the system’s false alarm rate.

The management platform includes a data processing module, a management module, and a visualization module. The data processing module includes a data acquisition module, a pattern recognition module, and a data storage module.

The pattern recognition module uses intrusion recognition algorithms to analyze and process the collected data.

The management module includes data management, user management, and alarm management. Data management includes databases and data retrieval; User management includes adding, deleting, and modifying users.

The visualization module includes a human-machine interface and data visualization. The human-machine interface includes a user login interface, a system main interface, and a settings interface; Data visualization includes raw signal graph, differential signal graph, signal energy graph, and signal zero crossing rate graph.

The management platform manages multiple warning subsystems, which are interconnected through a local area network or the Internet, and can be remotely viewed through a mobile app or client. The sensing terminal is a passive fiber optic monitor that can transmit coherent optical signals back; The sensing terminal, as the front-end detection part, is completely passive, does not require power supply, and has a high level of lightning protection, achieving the effect of low energy consumption and easy maintenance. The sensor initiator is the starting position for device monitoring. The alarm is a buzzer that sounds to provide real-time alerts for abnormal situations.
