Distributed optical fiber connected to a monitoring system of several tens to hundreds of kilometers length of optical fiber or cable to achieve vibration, strain and temperature within the range of hundreds of kilometers while online real-time monitoring, monitoring of up to centimeter range resolution, precision strain micron , 0.1 to 1 ° C temperature accuracy, the dam body may be used to monitor the micro-cracks, deformation monitoring cracks in the tunnel, bridge girders strain monitoring, monitoring the cable tension, cracks pipeline leak detection, monitoring slope, high temperature fire alarm, etc. engineering, communications cable equipped with common monitoring and data transmission can be realized within the range of hundreds of kilometers, without additional laying fiber optic cable, truly a combined communications cable and monitor cable, almost no construction costs, can be realized on a temperature in the range of one hundred kilometers and micro deformation monitoring.
2D and 3D scanning dam slope can be achieved in 15 minutes laid installation, no wiring, without the front end of the sensor 10 minutes fast scan, scan range 3 km, most deformation monitoring precision 0.1mm, is known as the most advanced engineering strain monitoring techniques.
A micro-dimensional deformation monitoring radar, may be implemented within 2 km, high-speed scanning of the one-dimensional structures, such as bridges, high-rise buildings, high-rise structures and the like, the maximum scan frequency of 100Hz, the most accurate up to 0.01mm, no wiring, without laying any sensor, 10 minutes to complete the host to set up, beyond all traditional monitoring techniques, called technological revolution to monitor the history of human engineering, will lead the monitoring project into a new era, it will go down in history.
Optical fiber sensing technology and radar monitoring techniques, a common cable 1 ~ 3mm in diameter (or diameter of 0.2mm bare fiber), can achieve the temperature and humidity within several tens of kilometers to hundreds of kilometers, micro-strain, tensile stress load between, vibration, wind speed, wind direction, air pressure, rainfall, displacement, deflection, pressure, water, oil, earth pressure, velocity, angle, degree of metal corrosion, fouling the real time monitoring of physical quantities such ice load sensor in series, quasi distribution measurement, resistance to electromagnetic interference, all sensors passive optical components, high temperature resistance, corrosion environment, water resistance, wet conditions, maintenance-free, long life, high precision, low price cable, many low cost construction advantages, it is widely used in the harsh environment of complex petroleum, electricity, chemicals, rail, sea, tunnels, underground, mining and so on.
