Research On Perimeter Protection System Based On Optical Fiber Sensing Technology

With developing, safety protection has obtained more and more attention. The traditional perimeter protection system has some disadvantages like zone capacity limited, the cost is relatively high, the sensor unit is active, the sensor signal is susceptible to the surrounding environment, poor immunity to electromagnetic interference, low system cost-effective, what’s worse, it largely based on the detection of integrate multi-sensor, and did not form a sensor network in the true sense.Thus, for the lack of perimeter protection systems in the past, the paper based on optical fiber sensing technology, use network data transfer protocol, database technology and video surveillance technology designed a new perimeter protection system which contains fiber optic sensing, video surveillance, alarm linkage, monitoring platform and smart handheld terminal. The new system is all-digital design, the zone sensor module has "self-learning" function that can predict the invasion of information in advance, if the vibration signal is determined invasion signal, the monitor software will instantly link video surveillance, location maps, sound and light interaction zone alarm, and send text messages to the relevant personnel under SMS alarm, besides, the undergo staff can also grasp the real-time information of zones with app. Video surveillance network use digital video surveillance, digital signal transmission based on TCP/IP of Ethernet, solved the original analog video surveillance operation complex, limited monitoring area, low scalability and wiring problems. The entire system has lots of advantages such as high stability, high sensitivity, strong adaptability to the environment, low false positive rate and low underreport rate, the system working safe while reducing human labor work, conserving resources while improving the efficiency of the staff.
