Low-false-alarm low-cost optical fiber fence
The invention provides a low-false-alarm low-cost optical fiber fence, and the fence comprises a sensing cross rod which is disposed above the fence, the interior of the sensing cross rod is provided with an accommodation space, and a sensing optical fiber is disposed in the accommodation space in a penetrating manner; the multiple fixing supports are used for connecting the sensing cross rod and the fence, the bottom ends of the fixing supports are fixedly connected with the fence, and the top ends of the fixing supports penetrate through the bottom face of the sensing cross rod and extend towards the interior of the containing space; the plurality of jacking assemblies are used for jacking the sensing optical fibers; and each limiting assembly comprises a limiting ring arranged on the outer side of the fixing support in a sleeving mode, and a first spring is arranged between the limiting ring and the sensing transverse rod and used for enabling the sensing transverse rod to move in the direction away from the fixing support. According to the invention, the sensing cross rod is arranged to protect the sensing optical fiber and prevent the sensing optical fiber from being damaged, and meanwhile, the sensing cross rod is fixedly connected with an existing fence in cooperation with the fixing support, the jacking assembly and the limiting assembly, so that the existing fence does not need to be replaced, and the cost is effectively reduced.
本发明提供一种低误报低成本光纤围栏，包括：传感横杆，设置在围栏的上方，传感横杆的内部设有容纳空间，且容纳空间内穿设有传感光纤；多个固定支架，用于连接传感横杆与围栏，固定支架的底端与围栏固定连接，固定支架的顶端穿过传感横杆的底面向容纳空间的内部延伸；多个顶压组件，用于抵顶传感光纤；多个限位组件，每个限位组件均包括套设在固定支架外侧的限位环，限位环与传感横杆之间设置有第一弹簧，用于使传感横杆向远离固定支架的方向移动。本发明，通过设置传感横杆，以对传感光纤进行保护，避免传感光纤受损，同时配合固定支架、顶压组件和限位组件与现有的围栏固定连接，因此不需要更换现有的围栏，进而有效的降低成本。
