Entrance guard system based on radar sensing and image recognition

Abstract

An entrance guard system based on radar sensing and image recognition comprises a radar detection module, a mixer, an amplifier, a delayer, and a starting circuit which are cascaded in sequence. The output end of the starting circuit is connected with an illuminating lamp switch through a first relay. The output end of the starting circuit, a second relay, a picture collection module, and a microprocessor are sequentially connected with each other. The output end of the microprocessor is connected with an electronic lock of the entrance guard system. A radar detection module detects echo signals reflected by people entering the detection area, and the echo signals sequentially pass through the mixer, the amplifier, and the delayer to form a starting signal. The starting signal is sent to the input end of the starting circuit, and the starting circuit controls the first relay to pull the illuminating lamp switch in according to the starting signal; and meanwhile, the starting circuit triggers the picture collection module to collect pictures of people entering the detection area, and sends the pictures to the microprocessor. The electronic lock is opened after the microprocessor recognizes the character in the pictures. According to the entrance guard system based on radar sensing and image recognition, the automatic opening and closing of a door can be realized, and the illuminating control can be realized when the door is opened.

Description

technical field [0001] The invention relates to the field of gate control switches, in particular to a gate control system based on radar induction and image recognition. Background technique [0002] In order to facilitate users to open the door at night or in poor natural light conditions, corridor lights or door lights are usually installed at the access control, but these lights are usually controlled by voice control, temperature control or manual buttons. The sound-activated or temperature-controlled switch is often turned on before the person reaches the door, so the time period for turning on the light does not start when the person is at the door, which causes the light to go out halfway through the door and needs to be turned on again. However, the manual button switch needs to be manually opened and manually closed. If you forget to turn off the light after opening the door, energy will be wasted.

AI Technical Summary

Problems solved by technology

The sound-activated or temperature-controlled switch is often turned on before the person reaches the door, so the time period for turning on the light does not start when the person is at the door, which causes the light to go out halfway through the door and needs to be turned on again

The manual button switch needs to be opened and closed manually. If you forget to turn off the light after opening the door, it will lead to waste of energy.

[0003] On the other hand, sometimes people have more things in their hands, and it is very inconvenient to take the key to open the door.
