Embodiment Construction

[0025] Below in conjunction with accompanying drawing and concrete example for further description:

[0026] Such as Figure 8 As shown, the sensing cable alarm method for perimeter protection in the present invention is to use a special sensing cable remote connection to a special adapter terminal for impedance matching. The intrusive stress change signal is sent to the band-pass shaping filter amplifier circuit. The signals amplified by digital-analog hybrid filtering and wave shaping are sent to the intrusion pattern recognition circuit, and analyzed and compared with various preset intrusion characteristic patterns, and at the same time, the interference factors such as wind disturbance in the natural environment are screened; the effective intrusion The action signal is sent to the alarm signal linkage control circuit, and the control circuit realizes the linkage with the safety protection equipment, and the bus system data transmission with the monitoring center. The pe...

Abstract

In order to provide alarming technique of sensing cable to replace high voltage protection electrical grid, following measures are utilized: signal of stress variation is collected by using double cords sensing cable 2 having shielding layer with impedance adaptive terminal being remote connected; signal processing is carried out by band pass amplification circuit 3 with reshaping and filtering functions and circuit 4 for recognizing mode of invasion. Alarming is through the coordinated control circuit for alarming signals, and protection circuit 6 for guarding against demolition is utilized. The method possesses advantages of high sensitivity, and interference immunity, as well as features of reasonable structure, easy of installation, and coordinated alarming for following actions of invader: climbing, treading, cutting, pulling, tearing down and striking.

Description
