Article anti-theft rotary barrier door based on electronic tag

Abstract

The invention discloses an article anti-theft rotary barrier door based on an electronic tag. The article anti-theft rotary barrier door comprises rotary door frames which are installed on the groundand symmetrical left and right, wherein an exiting and entering space is formed between the two rotary door frames, a rotary cavity located inside the ground is formed on the lower side of the exitingand entering space, and a ratchet wheel cavity is formed in the bottom wall of the rotary cavity. Whether a person steals an article or not can be accurately detected through a sale information record of the electronic tag corresponding to the article, the person is temporarily trapped and prevented from escaping through the rotation limiting and person trapping functions of a barrier ring and arotating shaft, and meanwhile, normal exiting and entering of other persons can further be guaranteed, and the trapped person is released, controlled and asked after security personnel come; and the probability that the thief forcibly escapes can be greatly reduced through the automatic person trapping function of the anti-theft rotary barrier door, and meanwhile the occurrence of theft events canbe reduced.
