| 摘要 |
The present invention relates to a device for detecting intrusion for an array of wires of a fence consisting of two end poles between which are stretched the wires (F) substantially horizontally. The device comprises detection means able to detect the displacement of at least one wire with respect to the other wires. Said detection means comprise: at least first and second elements (2) mounted one above the other and to each of which is fixed a corresponding wire (F), said first and second elements being capable of displacement in translation and/or in rotation in respect of one another, and a detection member (6) for detecting the displacement of the first element with respect to the second element under the effect of an external force applied to the wire fixed to the first element. |
