Abstract

A net-type safe fence with an infrared bijection audible and visual alarm function comprises a safe fence body. The safe fence body comprises a four-way infrared bijection detector (1), an audible and visual alarm (2), an audible and visual alarm base (3), a fixing pin (4), a rotary fixing shaft (5), an upper pulled net hook fixing plate (6), a rotary sleeve (7), a lower pulled net hook fixing plate (8), a fence body base (9), a pulled net (10), an upper pulled net hook (11) and a lower pulled net hook (12). An infrared transmitter of one safe fence body is coordinated with an infrared receiver of another safe fence body, so that infrared bijection deployment of the two safe fence bodies is realized, and when a person steps over pulled nets between the two safe fence bodies, the audible and visual alarms send out audible and visual alarm and upload alarm signals to a background host. Through the coordination of multiple net-type safe fences, integrated deployment of safe fence net pulling and infrared bijection in a certain area can be realized.
