INNO fibre optic temperature sensors ,temperature monitoring systems.
Distributed fiber optic is a security monitoring system based on fiber optic sensing technology, which uses fiber optic as a sensor and transmission medium to achieve real-time monitoring and alarm of long-distance targets. This technology has advantages such as high sensitivity, strong anti-interference ability, and long transmission distance, making it particularly suitable for long-distance and large-scale security deployment scenarios.
Technical advantages
1. Long distance transmission capability: Distributed fiber optic technology adopts optical signal transmission, which has advantages such as long transmission distance and low attenuation. Even at distances of tens or even hundreds of kilometers, it can maintain signal stability and clarity, meeting the needs of long-distance defense.
2. High sensitivity monitoring: Distributed fiber optic sensors can monitor real-time changes in physical quantities such as vibration and temperature around the fiber optic, and even small disturbances can be accurately captured. This enables distributed fiber optic technology to promptly detect and alert potential security threats.
3. Strong anti-interference ability: Fiber optic, as a transmission medium, has a natural ability to resist electromagnetic interference. In complex electromagnetic environments, distributed fiber optic technology can maintain stable performance and ensure the reliable operation of safety monitoring systems.
4. Easy deployment and maintenance: Distributed fiber optic technology uses optical fibers as sensors, without the need for additional cables or installation of other equipment, reducing deployment costs and maintenance difficulties. Meanwhile, the durability of optical fibers also ensures the long-term stable operation of the system.
Application scenarios
Border line security monitoring: In long-distance and large-scale security deployment scenarios such as border lines, distributed fiber optic technology can monitor the security status of border lines in real time, detect and report illegal border crossing behaviors in a timely manner.
Oil and gas pipeline protection: Distributed fiber optic technology can monitor real-time changes in parameters such as vibration and temperature around the pipeline, timely detect potential safety hazards, such as poaching and destruction, and ensure the safe operation of oil and gas pipelines.
Smart grid security monitoring: In the smart grid, distributed fiber optic technology can monitor changes in the surrounding environment in real time, timely detect and handle potential security risks, and ensure the stable operation of the power grid
