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. Currently, fiber optic sensors can be used to detect physical quantities such as pressure, ҳарорат, ларзиш, current, voltage, and magnetic field. Its fields include national defense and military, aerospace, civil engineering, барқ, energy, environmental protection, medicine, ва ғайра., and the development space is very broad. Distributed fiber 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, oil pipelines, 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. Бо рушди муттасили технологияи ҳассос, талаботи одамон ба технологияи сенсор низ руз то руз меафзояд. It is rare to find vibration sensors that simultaneously meet the conditions of high sensitivity, камхарҷ, раванди омодасозии оддӣ, and good stability. Дар процесси хис кардан ва ошкор кардан, ҳассосият ва устуворӣ омилҳои асосии таъсирбахши техникӣ мебошанд, дар ҳоле ки раванди тайёрӣ ва арзиш омилҳои муҳими таъсирбахши истеҳсолоти саноатӣ мебошанд. Vibration sensors that combine these advantages are receiving increasing attention and favor.
Ҳисси ларзиши нахи оптикӣ 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.

Дар айни ҳол, 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, муқовимат ба дахолати электромагнитӣ, ва муқовимат ба зангзании.
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. Аммо, 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; Ҳамзамон, they are susceptible to environmental limitations such as high and low terrain conditions, twists and turns, bends, ва ғайра., and are not suitable for harsh climates. They are easily affected by natural climates such as high and low temperatures, strong light, dust, борон, барф, fog, frost, ва ғайра., 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. Дар Илова, this product can resist the interference of natural factors such as wind and rain, and is not affected by electromagnetic, lightning, radio signals, ва ғайра. It has high reliability and is easy to maintain.
