A perimeter security system for detecting climbing behavior by gravity sensing

Abstract

The present invention discloses a perimeter security system for detecting climbing behavior by gravity sensing. When an illegal person climbs over the perimeter wall, the illegal person applies weight to the coping stone, causing the elastic support mechanism to be compressed, increasing the force exerted by the coping stone on the gravity sensor. The gravity sensor transmits the detected signal to the controller, and the controller controls the buzzer to give an alarm, thereby realizing the detection of climbing behavior by gravity sensing and providing security at the perimeter wall. At the same time, the top cover is arranged in a frustum shape to prevent illegal persons from climbing over the perimeter wall from the top cover. The setting of the pressure applying mechanism, in cooperation with the elastic support mechanism, can adjust the initial pressure of the coping stone on the gravity sensor, facilitating debugging during installation. Moreover, the pressure applying mechanism is fixedly connected between two adjacent coping stones, preventing the coping stone from falling and improving the installation stability.
