Problems solved by technology

However, when the previous person passes, another person follows him. If the interval between two people's entry is short enough, infrared access control may not be able to detect the trailing entry. Unauthorized personnel can use this vulnerability to follow someone. Authorized personnel enter and exit the passage, so the safety of the entrance and exit of the passage cannot be guaranteed

Embodiment 1

[0027] The invention provides an infrared access control judgment method, which is applied to infrared access control equipment. The infrared access control equipment includes 4 infrared emitting units and 4 infrared receiving units, and the 4 infrared emitting units and 4 infrared receiving units are set correspondingly, and the 4 infrared receiving units When any infrared receiving unit in the unit does not receive the signal sent by the corresponding infrared emitting unit, it sends an infrared trigger signal.

[0028] Specifically, infrared access control equipment can be installed in any place that needs to control the entrance and exit passages, for example, it can be installed in places such as intelligent building entrances and exits, library entrances and exits, unmanned supermarket entrances and exits, etc., to detect and control the personnel entering and exiting the passage. The 4 pairs of infrared emitting units and infrared receiving units included in the infrared...

Abstract

The invention provides an infrared access control judgment method and infrared access control equipment. The infrared access control equipment comprises four infrared transmitting units and four infrared receiving units, the four infrared transmitting units and the four infrared receiving units are correspondingly arranged, and any one infrared receiving unit in the four infrared receiving units transmits an infrared trigger signal when not receiving the signal transmitted by the corresponding infrared transmitting unit; the infrared entrance guard judgment method is applied to the infrared entrance guard equipment. By means of the infrared access control judgment method and the infrared access control equipment, the state of people passing through the passageway entrance and exit can be accurately judged, access of people is limited, only one person completely passes through the passageway entrance and exit, the next person can enter the passageway entrance and exit, and otherwise, anerror process can be entered.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an infrared access control judging method and infrared access control equipment. Background technique [0002] In the prior art, an access control system is usually used to control the entrance and exit of passages, and the access control system determines whether to pass through according to the authority of passers-by. Generally, only one person is allowed to pass through at a time. When the person is passing through, the infrared access control device is used to detect the number of people passing through. Infrared access control is generally composed of an infrared transmitting device and an infrared receiving device. By default, the infrared receiving device receives the transmitting signal for a long time. / Things pass. However, when the previous person passes, another person follows him. If the interval between two people's entry is short enough, infrared access cont...
