Vibration has always been an important research topic in the field of science and technology. Vibration sensors are commonly used in various fields such as seismic wave detection, fiber optic hydrophones, non-destructive testing, oil and gas exploration, industrial process control, and structural health monitoring. Traditional vibration sensors include capacitive or piezoelectric sensors, which have high sensitivity but are not suitable for high voltage, high magnetic field places such as substations. Fiber optic vibration sensors have a wide range of applications in power system facility operation and safety monitoring due to their natural insulation, immunity to electrical and magnetic interference, small size, light weight, and strong multiplexing capability. They have always been a hot research and application topic both domestically and internationally.

Fiber optic vibration sensors detect changes in optical parameters such as light intensity, makhetlo a mangata, bolelele ba maqhubu, mohato, and polarization state in optical fibers by sensing external vibrations. The purpose of detecting external parameters is achieved by detecting changes in optical parameters in optical fibers. In optics, a Fabry Perot interferometer is a multi beam interferometer composed of two parallel glass plates, where the inner surfaces of the two glass plates facing each other have high reflectivity. In fiber optic vibration sensors, the Fabry Perot interferometer has a unique attraction because it can provide a non-contact and disturbance free vibration analysis device, and has also been proven to have significant performance advantages in vibration and displacement measurement.

Vibration measurement has a wide range of applications in many fields. These fields include the detection of sound and ultrasonic signals, earthquake monitoring, oil exploration, vibration modal analysis of various mechanical systems, and water listening systems. Hajoale, existing vibration sensors can be divided into electromagnetic vibration sensors, variable capacitance vibration sensors, and piezoelectric vibration sensors according to their different principles.

These vibration sensors are all electrical sensors. There is another type of vibration sensor that corresponds to electrical sensors, namely fiber optic vibration sensors. Compared with electrical sensors, fiber optic vibration sensors have significant advantages such as anti electromagnetic interference, khanyetso ea kutu, long service life, small size, and the ability to achieve multi-point distribution measurement through optical wavelength multiplexing. Ka hona, they play a huge role in situations where traditional electrical sensors cannot be used (such as flammable and explosive). Holim'a moo, fiber optic vibration sensors also have the advantage of high sensitivity, so they play a key role in many applications that require detection of weak vibration signals. High sensitivity fiber optic vibration sensors often use fiber optic interference technology, and interferometric fiber optic sensing systems are susceptible to external environmental changes, such as temperature fluctuations often causing drift in interferometric fiber optic sensing systems. The main method to solve this problem is to adopt some form of compensation technology.

The S-type vibrating fiber optic perimeter alarm is the latest product developed by FJINO based on the self-developed vibrating fiber optic perimeter alarm system, one cable vibrating fiber optic perimeter alarm system, and network-based vibrating fiber optic perimeter alarm system, which complement each other’s strengths and comprehensively utilize the advantages of the product.
