It is connected.
Sensing module includes sensing terminator, sensing optic cable, sensing isolator, is arranged in monitoring area, displacement sensing list
First acquisition monitoring area movable signal, sensing optic cable generates mobile optical signal, and optical signal transmission is shaken to sensing isolator
Dynamic sensing unit acquires monitoring area vibration signal, and sensing optic cable generates the optical signal of vibration, and by optical signal transmission to sensing
Isolator, sound sensor unit acquire monitoring area voice signal, and sensing optic cable generates the optical signal of sound, and optical signal is passed
It is defeated to arrive sensing isolator.Sensing isolator transmits information to transceiver module by conducting optical cable, and transceiver module is to from sensing
The information transmit-receive of module and monitoring center, photo-coupler are connect with DSP module, carry out the docking of information.
DSP module uses TMS320F2812 chip, since invasion vibration signal is mostly low frequency signal, in order to improve system
To the response sensitivity of outside invasion vibration signal, central controller controls alarming threshold value, when the received optical signal width of DSP module
When degree is higher than alarming threshold value, the external interrupt of DSP module is triggered.The signal processing terminal generates optical signal, is sent by conducting optical cable
Enter sensing optic cable, sensing optic cable is located between sensing isolator and sensing terminator, is layed in the region to be protected, the external world enters
The feature that caused various vibrations will change transmitted optical signal via sensing optic cable is invaded, the signal processing terminal acquisition variation
Optical signal identifies intrusion behavior according to signal characteristic value, then carries out alert process.After DSP module acquires a group information,
Shorter for the disturbing signal duration by handling the signal of sensing optic cable, triggering frequency is lower, alerts door by setting
Limit and signal duration can be filtered out and be disturbed caused by most of incident in the number of unit time intrusion event
It is dynamic, judge whether to make intrusion alarm, monitors common various intrusion behaviors, while can recognize that non-intrusive behavior.In addition to report
Outside alert signal, system also provides failure alarm signal and dismantling-proof alarming signal, once sensing optic cable is destroyed or signal processing is whole
End is opened, and can issue corresponding warning message.It is failed to report for anti-locking system, the signal data for having buffer memory to acquire guarantees
In information process, if any new invasion signal, it can also be acquired signal and be saved.The signal processing terminal according to
The result of DSP module signal carries out alert process, and processing result is passed through 485 bus transfers to central controller, by center
Controller is handled again, and processing information is transferred to PC machine.
It is emphasized that embodiment described in the utility model be it is illustrative, without being restrictive, therefore this reality
Embodiment described in specific embodiment is not limited to novel, it is all according to the present utility model by those skilled in the art
The other embodiments that technical solution obtains also belong to the range of the utility model protection.
