Vibration fiber optic perimeter sensing monitoring system, tshuab, characteristics-INNO

Since the mid-1970s, after just over 20 years of rapid development, fiber optic sensing technology has made significant progress. Due to its unique advantages, it has been widely researched and applied, and fiber optic sensors for measuring various parameters have emerged. Tam sim no, fiber optic sensors can be used to detect physical quantities such as pressure, kub, kev vibration, current, voltage, and magnetic field. Its fields include national defense and military, aerospace, civil engineering, electricity, energy, environmental protection, medicine, lwm., and the development space is very broad. Distributed fiber ntau optic vibration sensors have become a research hotspot both domestically and internationally in recent years due to their simple structure, long detection range, and immunity to electromagnetic interference. Distributed fiber optic vibration sensing devices are urgently needed technologies in fields such as national defense, cov kav dej, and power. This technology can be used to monitor real-time intrusion of border lines, damage and theft of oil pipelines, and theft and damage of power cables, achieving the protection of national property and life safety. Nrog rau kev txhim kho txuas ntxiv ntawm kev hnov cov thev naus laus zis, people’s demand for sensor technology is also increasing day by day. It is rare to find vibration sensors that simultaneously meet the conditions of high sensitivity, tus nqi qis, txheej txheem npaj yooj yim, thiab zoo stability. Nyob rau hauv tus txheej txheem ntawm kev hnov thiab nrhiav pom, rhiab heev thiab stability yog lub ntsiab technical influencing yam, thaum cov txheej txheem npaj thiab tus nqi yog qhov tseem ceeb cuam tshuam rau hauv kev tsim khoom. Vibration sensors uas muab cov txiaj ntsig zoo no tau txais kev nyiam thiab nyiam.
Fiber optic vibration sensing 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, yog li no nrhiav kev vibration ntawm cov khoom.

Tam sim no, the perimeter security system based on IoT technology has gone beyond the laboratory and has gained recognition from users in multiple application areas related to public safety, especially in airports, prisons and other places. The perimeter security system in the new era must be able to identify and respond to various intrusion events in a timely manner, and must have characteristics such as long-distance monitoring, high-precision positioning, low energy dependence, high environmental tolerance, tiv thaiv electromagnetic cuam tshuam, and corrosion resistance.
For many years, traditional perimeter security solutions such as infrared radiation, video surveillance, microwave radiation, leaky cable, vibrating cable, electronic fences, and power grids have made their due contributions to social security. Txawm li cas los, due to some objective technical conditions and other factors, there are still some common or individual shortcomings. Traditional solutions such as infrared have lower protection levels and are easy for intentional intruders to bypass or avoid; Tib lub sijhawm, they are susceptible to environmental limitations such as high and low terrain conditions, twists and turns, bends, lwm., and are not suitable for harsh climates. They are easily affected by natural climates such as high and low temperatures, strong light, dust, rain, snow, fog, frost, lwm., resulting in a high false alarm rate; Leakage cable and vibration cable alarm belong to cable sensing, and the sensing part is active, resulting in high system power consumption; Electronic fences, power grids, and other solutions also have certain hazards.

Intrusion detection system (also known as vibration fiber optic perimeter alarm system) is a fiber optic vibration intrusion detection product designed and developed using the principle of laser interference. Its vibration sensing fiber optic cable can be laid along fences, walls (referred to as hanging nets), or underground. When an intrusion or destruction event occurs, the system will immediately issue an alarm. Ntxiv rau, this product can resist the interference of natural factors such as wind and rain, and is not affected by electromagnetic, lightning, radio signals, lwm. It has high reliability and is easy to maintain.
