Manufacturer of DAS distributed fiber optic vibration safety protection sensing and monitoring technology-INNO

The distributed fiber optic all-weather excavation monitoring technology based on THE has engineering advantages such as high sensitivity (about 10n ε), khoảng cách giám sát dài (lên tới hàng chục km), độ chính xác định vị cao (in meters), no need for outdoor power supply, convenient deployment, and strong concealment. By utilizing the backward Rayleigh scattering of light pulses in optical fibers, real-time continuous monitoring of disturbance information on fiber optic links can be achieved. External disturbance signals such as excavation and blasting cause fiber optic deformation by generating soil vibrations, which are then detected by DAS systems. This technology uses distributed quantitative signal demodulation and pattern recognition technology to monitor disturbances along optical fibers online, combined with spatial positioning methods based on array signal processing for disturbance source stereo positioning, ultimately achieving distributed all-weather stereo monitoring.

Với sự phát triển không ngừng của công nghệ cảm biến, nhu cầu về công nghệ cảm biến của con người cũng ngày càng tăng cao. It is rare to find vibration sensors that simultaneously meet the conditions of high sensitivity, chi phí thấp, quá trình chuẩn bị đơn giản, và ổn định tốt. Trong quá trình cảm nhận và phát hiện, độ nhạy và độ ổn định là những yếu tố ảnh hưởng kỹ thuật chính, trong khi quá trình chuẩn bị và chi phí là những yếu tố ảnh hưởng quan trọng trong sản xuất công nghiệp. Vibration sensors that combine these advantages are receiving increasing attention and favor.
Cảm biến rung sợi quang technology is a type of technology that changes the characteristics of the transmitted light in optical fibers when the fiber optic sensor is affected by external interference. By using special sensing equipment to collect and analyze signals, changes in the characteristics of light can be detected, thereby detecting the vibration of objects.

Functional characteristics of distributed fiber optic vibration monitoring system

1. Hiển thị cảnh báo trực quan: Provides a visual display interface that maps the position of the sợi quang cable to the image through a graphical configuration module. Once an intrusion accident occurs at a certain point, the alarm information is directly displayed on the image, which is visually intuitive.

2. Vibration curve display: The system can display the vibration signal distribution curve of the entire optical cable in real time. When the vibration signal strain is abnormal in a certain area, the real-time information of that area can be displayed through the curve.

3. Partition/graded event alarm: Cung cấp nhiều phương thức báo động linh hoạt, and alarm parameters can be set in grades and regions.

4. Historical statistical analysis: Provides statistical analysis of historical vibration data, bao gồm: a The vibration distribution curve of different positions of the optical cable at a certain time b. The vibration change curve of a certain point of the optical cable during a certain period of time.

5. Intelligent pattern recognition: The system can obtain information such as the time, vị trí, and trend of vibration events. By analyzing the vibration waveform and extracting characteristic signals, combined with big data, học máy, and neural network recognition algorithms, the type of vibration event can be determined, and intrusion events can be warned in advance to ensure operational safety.
