Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of electronic fence, and mainly relates to an adjustable electronic fence sensor structure. BACKGROUND

[0002] An electronic fence is a security protection system based on electronic technology, which realizes real-time monitoring and intrusion detection of a specific area through virtual or physical boundaries. Its core function is to identify and respond to border crossing behavior through the coordinated work of sensors, controllers and alarm devices.

[0003] The existing electronic fence is widely used in coal mines and mines, but due to its poor application environment, the installation is not necessarily a flat reference surface. In many cases, the installation reference surface may be a concave-convex pit surface or a cliff wall. The rod of the traditional electronic fence is usually a straight rod and cannot be adjusted at an appropriate angle. If the base is not flat, the electronic fence may not receive the signal sent by the adjacent fence, which leads to the problem of insufficient precision and easy interference of the traditional electronic fence sensor in detecting intrusion behavior.

[0004] In order to improve the accuracy and reliability of detection, an adjustable electronic fence sensor structure needs to be developed, which can flexibly adjust the angle parameters according to different environmental conditions and application scenarios, so that the transmitting end and the receiving end of the electronic fence are parallel to each other, so as to better identify the intrusion behavior and reduce the false alarm rate and the missed alarm rate.
