Embodiment 1

[0016] Embodiment 1: with reference to attached figure 1 and 2 . A multi-beam infrared fence detector with intrusion direction recognition, it includes an infrared transmitter 1 and an infrared receiver 2, and a multi-beam infrared grating is formed between the infrared transmitter 1 and the infrared receiver 2 to form a planar defense net 3, said Each beam of infrared emitters contains at least one infrared transmitter 4 and two infrared receivers (infrared receiver A5 and infrared receiver B6), and the arrangement of the two infrared receivers in each infrared beam is X-axis It is still the Y axis, which is arranged one after the other in the direction perpendicular to the X axis and the Y axis. One of the two infrared receiving heads is an infrared trigger head, and the other is an infrared non-trigger head. Controlled by the infrared trigger head or controlled by the infrared non-trigger head, any one of the two infrared receivers can be used as either an infrared trigge...

Embodiment 2

[0018] Embodiment 2: On the basis of Embodiment 1, refer to accompanying drawings 3-5. An infrared protective net composed of a multi-beam infrared fence detector with intrusion direction recognition, it includes a rectangular frame 7 or a non-rectangular frame, and the rectangular frame or non-rectangular frame is on the side of the frame column relative to the frame column from top to bottom or from the left And the right interval is distributed with many beams of infrared transmitters 1, and the other side frame column of the opposite frame column is distributed with multiple beams of infrared receivers 2 at intervals from top to bottom or from left to right and the multiple beams of infrared receivers 2 are opposite to it The infrared emitters 1 constitute an infrared fence detector network 3, and the multi-beam infrared emitters 1 and the multi-beam infrared receivers 2 on the non-rectangular frame are opposite one by one.

Embodiment 3

[0022] Embodiment 3: On the basis of Embodiments 1 and 2, refer to accompanying drawings 3-5. A detection method for an infrared protective net composed of a multi-beam infrared fence detector with intrusion direction recognition, a multi-beam infrared transmitter distributed in a rectangular frame or a non-rectangular frame and a corresponding multi-beam infrared receiver constitute an infrared fence detection The two infrared receiving heads in each bundle of infrared receivers, one in front and one in the back, the front infrared receiving head is the triggering infrared receiving head or the rear infrared receiving head is the non-triggering infrared receiving head. When entering from the direction of the head, the infrared trigger head triggers the infrared fence detector net to alarm, and when people or objects enter from the direction of the non-triggering infrared receiving head, the infrared trigger head does not trigger the infrared fence detector net to alarm.

Abstract

The invention relates to an anti-theft device by utilizing infrared detection and directions to trigger alarms, which can particularly effectively achieve the aim of sending off an alarm if illegal and no alarm if legal. A plurality of infrared emitters distributed in rectangular frames or non-rectangular frames and a plurality of corresponding infrared receivers form an infrared barrier detector net, and a front infrared receiving head and a rear infrared receiving head in each infrared receiver are respectively a triggering infrared receiving head and a non-triggering infrared receiving head; when a person or an object enters from the direction of the triggering infrared receiving head, an infrared triggering head triggers the infrared barrier detector net to send off the alarm, and when the person or the object enters from the direction of the non-triggering infrared receiving head, the infrared triggering head does not trigger the infrared barrier detector net to send off the alarm.

Description

technical field [0001] The invention relates to an anti-theft device using infrared detection and direction triggering alarm, especially capable of effectively identifying the direction of an intruder to achieve the purpose of legal non-alarm and illegal alarm, and belongs to the field of alarm manufacturing. Background technique [0002] CN2710063Y, the name "mutual emission type multi-beam infrared fence detector", includes an alarm device and a pair of infrared monitors which are arranged facing each other and are electrically connected to each other. Each infrared monitor consists of a casing, a circuit board, a transmitter, and a receiver. , and a control circuit arranged on the circuit board. The shell is provided with a light-transmitting window, and the alarm device, transmitter and receiver are all electrically connected to the control circuit. In addition, the transmitter at any end of the pair of infrared monitors One-to-one correspondence is maintained with the t...
