Description
Technical Field
The present invention relates to the field of sensors. More particularly, the present invention relates to a sensor for a tension fence.
Background
The tension fence is composed of an anchor column, a tension line, a spiral column, a sensor, a data line and a lightning protection box. A group of tension line steel wires (barb or no barb) horizontally tensioned between the anchor columns form a tension line array wall; the anchor post is used for fixing the tension line; the spiral column is used for keeping the tension lines to be closely parallel and limiting the movement of the tension lines in the vertical direction; the studs are placed at regular intervals along the tension line array wall. The sensor column is used for installing and fixing a sensor for detecting tension change of the tension line and is positioned between the two anchor columns.
The sensor on the sensor post is fixed to the tension wire and detects tension changes caused by an intruder attempting to move, cut or climb the tension wire. At present, the sensor used for the tension fence is usually a switching value sensor, and an intruder is warned by switching on and off of a circuit switch. When an intruder intrudes, the tension wire is pulled, and the sensor is triggered when the change of the wire tension of the tension wire reaches the set standard; and the switching value alarm signal is transmitted to a control unit of the local alarm control system through a data line.
Tension fences are typically installed outdoors. When the tension fence is located in an extreme environment, such as high temperature or severe cold, the tension wire is easy to expand with heat and contract with cold.
