Face identification-based intelligent entrance guard system

The invention discloses a face identification-based intelligent entrance guard system. The face identification-based intelligent entrance guard system comprises a light intensity sensor, an illuminating lamp, a pyroelectric sensor, a camera, a control module, a voice prompting circuit, a first relay, a second relay, a memory module, and an electronically operated gate; the control module is connected with the light intensity sensor, the pyroelectric sensor, the camera, the voice prompting circuit, and the memory module separately; the illuminating lamp is connected with the control module via the first relay; and the electronically operated gate is connected with the control module via the second relay. The face identification-based intelligent entrance guard system is simple in structure, is convenient to use, is capable of solving problems that photographing is unclear because of insufficient light, and characteristic data cannot be extracted, and realizing automatic matching identification, and is safe and reliable.
