Round-Guard System Based on the Vibration Cable Transducer
Adopting a new kind of transducer technology vibration cable technology, can round-guard in large region without bodyguard whole day, and using display and warning on the end equipments may judge abnormal conditions occurred in what time and in what place. The system makes use of quadratic and own source filter, suppress the disorder waves induced in transducer, install two-rank amplifier which kernel being operation amplifier, especially for micro-vibration originating undercut can judge illegal invader, and can judge the invaders are human or heavy equipment according to vibration intensities.
