Invisible security net

Abstract

The invention discloses an invisible security set which comprises an upper frame, a lower frame and blocking ropes. The upper frame is arranged on an upper edge of a window, and the lower frame is arranged on a lower edge of the window. The blocking ropes are arranged between the upper frame and the lower frame at intervals in a penetrating mode. The upper frame and the lower frame are respectively provided with a plurality of installation holes for the blocking ropes to penetrate through. Arc plates are arranged on the upper frame and the lower frame and located between two adjacent installation holes, and the blocking ropes penetrate through the installation holes in the upper frame and the lower frame at intervals and are wound on the arc plates. The blocking ropes, the upper frame, the lower frame and the arc plates together form a net structure, and the blocking ropes respectively comprise sensing fibers, an inner protective layer and an outer protective layer. The inner protective layers are arranged outside the sensing fibers, and the outer protective layers are arranged outside the inner protective layers. The tail ends of the sensing fibers are connected with a test unit which is connected with an alarm. The invisible security set is fixed on a door and a window or a balcony through the high-strength blocking ropes containing the sensing fibers. Once the blocking ropes break, alarming is sent out, and the protection effect is realized. The invisible security set is convenient to install, low in cost, attractive and elegant, and good in visual effect.

Description

technical field [0001] The invention relates to an anti-theft net, in particular to an intelligent invisible anti-theft net containing optical fibers. Background technique [0002] There are many types of existing anti-theft nets. At present, most of them are cage-type anti-theft nets made of steel rods or steel pipes. However, this kind of protective net has potential safety hazards, and it is difficult to escape quickly in case of emergency situations such as indoor fire. In addition, this kind of anti-theft net is passive, and the existing new tools can be easily cut without being discovered, which has a relatively large security risk. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art and provide an invisible anti-theft net, which is fixed on doors, windows or balconies by using high-strength blocking ropes containing sensing optical fibers. Once the blocking rope breaks, an alarm wil...
