[0002] In the field of fence processing, anti-theft is an eternal theme. Various fence manufacturers have designed many drawings and ideas for anti-theft, and gradually developed into two branches, interception and alarm. The interception mainly sets obstacles above the fence, including setting There are spikes on the grid and fence mesh, and the alarm type is to install cameras and sensors on the fence. Since the grid or spikes above the fence are more harmful to the human body, from the perspective of humanized management, the mainstream trend is It is developing in the direction of alarming, but installing cameras and sensors on the fence will easily break down if it is exposed to wind and rain for a long time, and it will be damaged by man-made when installed outside. A pressure alarm device with sensors installed in the fence posts is needed
