Sensor for taut wire fences

摘要

A sensor for an intrusion detection fence of a taut wires type and a method implemented in its operation, wherein the sensor is a multi-axes accelerometer that is installed on the sensors' pole of the fence while inclined relative to the fence taut wire unto which it is connected, and the sensor is connected to fence taut wire via a movement converting means such that from an instant of loading the taut wire as happens when an intrusion attempt through it occurs, the movement converting means converts the movement of the taut wire unto a rotational movement of the sensor that is amenable to be sensed in at least two axes.

主权项

1. An intrusion detection fence of a taut wires type comprising:
two anchoring poles that are positioned at a distance from one another; a plurality of wires that are stretched taut between said two anchoring poles; at least one sensors' pole that is located between two said anchoring poles; and at least one sensor that is installed on said at least one sensors' pole, wherein said at least one sensor is linked with at least one of said plurality of wires for sensing phenomena that accompany an attempted intrusion through said fence; wherein said intrusion detection fence is characterized by that; said at least one sensor is a multi-axis accelerometer that is installed on said at least one sensors' pole and connected to said at least one of said plurality of wires via a movement converting means, which from an instant of loading said at least one of said plurality of wires as happens when an intrusion attempt through it occurs, converts a movement of said at least one of said plurality of wires to a movement of said at least one sensor that is amenable to be sensed by at least two axes of the multi-axis accelerometer.
