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 ANG has engineering advantages such as high sensitivity (about 10n ε), mahabang distansya ng pagsubaybay (hanggang sampu-sampung kilometro), mataas na katumpakan ng pagpoposisyon (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.

Sa patuloy na pag-unlad ng teknolohiya ng sensing, Ang pangangailangan ng mga tao para sa teknolohiya ng sensor ay tumataas din araw-araw. Bihirang makahanap ng mga sensor ng panginginig ng boses na sabay-sabay na nakakatugon sa mga kondisyon ng mataas na sensitivity, mababang gastos, simpleng proseso ng paghahanda, at magandang katatagan. Sa proseso ng sensing at detection, ang pagiging sensitibo at katatagan ay ang pangunahing mga salik na nakakaimpluwensya sa teknikal, habang ang proseso ng paghahanda at gastos ay mahalaga na nakakaimpluwensya sa mga salik sa industriyal na produksyon. Ang mga sensor ng panginginig ng boses na pinagsasama ang mga kalamangan na ito ay nakakatanggap ng pagtaas ng atensyon at pabor.
Fiber optic vibration sensing Ang teknolohiya ay isang uri ng teknolohiya na nagbabago sa mga katangian ng ipinadalang ilaw sa mga optical fiber kapag ang fiber optic sensor ay apektado ng panlabas na interference. Sa pamamagitan ng paggamit ng mga espesyal na kagamitan sa sensing upang mangolekta at magsuri ng mga signal, ang mga pagbabago sa mga katangian ng liwanag ay maaaring makita, sa gayon ay nakikita ang vibration ng mga bagay.

Mga functional na katangian ng distributed fiber optic vibration monitoring system

1. Pagpapakita ng visual na alarma: Provides a visual display interface that maps the position of the fiber optic 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: Nagbibigay ng maramihang nababaluktot na paraan ng alarma, and alarm parameters can be set in grades and regions.

4. Historical statistical analysis: Provides statistical analysis of historical vibration data, kasama ang: 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, lokasyon, and trend of vibration events. By analyzing the vibration waveform and extracting characteristic signals, combined with big data, machine learning, 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.
