Problems solved by technology

The infrared trigger method is easily interfered by various heat sources and sunlight sources; the passive infrared penetration is poor, the infrared radiation of the human body is easily blocked, and it is not easy to be received by the detector; it is easily interfered by radio frequency radiation; when the ambient temperature and the human body temperature are close, Significant drop in detection and sensitivity, sometimes resulting in short-term failure
In addition, the installation environment of the ultrasonic radar trigger method is limited, and it must be installed in an open and unobstructed environment
If there is an obstacle in front of the device, it will cause a serious false touch, which will cause the device to fail to work normally; the trigger distance is short

Embodiment Construction

[0037] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] The content of the present invention will be described in detail below in conjunction with the examples.

[0039] refer to figure 1 As shown, it is a schematic flowchart of an intelligent control method for an access control system provided by an embodiment of the present invention. The invention provides an intelligent control method of an access control system, comprising:

[0040] S1, acquiring an input signal detected by the microwave radar;

[0041] S2, performing ADC sampling on the input signal to obtain an ADC value;

[0042] S3, by comparing the ADC value and the idle level value, it is judged whether it is a human body trigger;

[0043] S4, if so, automatically turn on the camera to perform face recognition verification on the human body.

[0044] Preferably, before step S3, it also includes init...

Abstract

The invention discloses an intelligent control method for an access control system and an access control system. The method comprises the steps of: S1, obtaining an input signal detected by a microwave radar; S2, performing ADC sampling on the input signal to obtain an ADC value; S3, comparing the ADC value with an idle level value so as to judge whether human body triggering occurs or not; and S4, if yes, automatically turning on a camera to perform face recognition verification on a human body. The method provided by the technical schemes of the invention is stable in triggering and is highin reliability, and can avoid mistaken triggering for an obstacle.

Description

technical field [0001] The invention relates to the field of security technology, in particular to an intelligent control method of an access control system and the access control system. Background technique [0002] At present, the building intercom access control host lacks efficient and reliable wireless human body detection trigger devices that can adapt to various complex environments. The current access control system mainly adopts infrared trigger mode and ultrasonic radar trigger mode. The infrared trigger method is easily interfered by various heat sources and sunlight sources; the passive infrared penetration is poor, the infrared radiation of the human body is easily blocked, and it is not easy to be received by the detector; it is easily interfered by radio frequency radiation; when the ambient temperature and the human body temperature are close, Detection and sensitivity are significantly reduced, sometimes causing short-term failures. In addition, the insta...
