When there is no user in front of the electric control door, that is, when the human pyroelectric infrared sensor does not detect the infrared signal emitted by the human body in the detection area, a human body detection signal is output to the main controller 20 as a low level signal. In this way, the main controller 20 can determine whether a user stands in front of the electric control door according to the currently received infrared signal, and output a check signal to the temperature measurement check module 30 when the user is confirmed to be in front of the electric control door.

At this time, the control module may control an unlocking device, such as a face brushing unlocking device or an access card unlocking device, disposed on the electric control door, to be in a working state. The unlocking device can be triggered by the current user through a face brushing or access card brushing mode, so that the electric control door can be normally opened to facilitate the user to pass.

If the current main controller 20 confirms that the user is yellow or red or that the body temperature of the user exceeds the preset alarm temperature, the main controller outputs a corresponding control signal to the control module, so that the control module confirms that the current user cannot enter.

Referring to fig. 3, in an embodiment, the epidemic prevention access control assembly further includes:

the voice module 40 is electrically connected to the main controller 20, and the main controller 20 is configured to output a voice output signal to the voice module 40 according to the temperature signal and the code scanning signal, so that the voice module 40 plays corresponding voice information.

In this embodiment, the voice module 40 may be implemented by a voice processing chip and a speaker, for example, SZY48G32C and its peripheral circuits and speakers. The main controller 20 outputs corresponding voice output signals to the voice module 40 according to the current temperature signal and the code scanning signal, and plays the phase by the voice module 40

And the corresponding voice information is used for prompting the body temperature state 5 and the health code state of the user to be entered currently by the user and/or the access control manager. For example, the user health code currently to be entered is a green code, and the body temperature is 36.5 c,

the main controller 20 outputs a corresponding voice output signal to the voice processing chip to make the voice processing chip output a corresponding voice signal to the speaker, so that the speaker can report the "green code, body temperature

5 it will be appreciated that in another embodiment, referring to fig. 3, the epidemic prevention access control assembly further comprises:

the voice control button 50 is electrically connected to the main controller 20, and is configured to output a voice control signal to the main controller 20 when triggered by a user, so that the main controller 20 adjusts the output volume of the voice module 40.

Referring to fig. 6 specifically, in conjunction with the circuit content of the foregoing embodiment, the main control chip U1 further has a voice control pin DATA and a volume setting pin KEY, where the voice control pin DATA is electrically connected to the voice module 40, for example, to a voice processing chip in the voice module 40, the voice control KEY 50 is implemented by using a KEY S1, a first end of the KEY S1 is connected to the volume setting pin KEY, and a second end of the KEY S1 is grounded.

After the main control chip U1 receives the code scanning signal and the temperature signal according to RX2 to confirm the health code type and the body temperature of the user currently waiting for 5 entries, the corresponding voice output signal is output to the voice module 40 through the voice control pin DATA in the above implementation process, so that the voice module 40 broadcasts the corresponding voice information. The master control chip U1 is pre-stored with volume control signals corresponding to the volume of the high, medium and low three gears respectively, when the master control chip U1 is just powered on, the volume control signals corresponding to the volume of the medium gear are defaulted to the voice module 40,

to control the volume level of the broadcast of the voice module 40 to remain at the mid-range volume. When the entrance guard manager wants 0 to adjust the voice broadcast sound, the key S1 can be pressed once, and at this time, the main control chip U1 receives a voice control signal (low level signal), and outputs a volume control signal corresponding to a high gear volume through the voice control pin DATA, so as to control the broadcast volume of the voice module 40 to be kept at the high gear volume, if the key S1 is pressed once again, the main control chip U1 outputs a volume control signal corresponding to a low gear volume through the voice control pin DATA, and if the key S1 is pressed once again, the main control chip U1 outputs a volume control signal corresponding to a medium gear volume through the voice control pin DATA and loops in sequence. Therefore, in practical application, the epidemic prevention entrance guard control component not only can broadcast the health code information and the body temperature information of the user to be entered currently in real time, but also can adjust the volume of broadcasting voice information by the current voice module 40 according to the requirements of entrance guard management staff, so that the convenience of using an entrance guard system is improved.

After the main control chip U1 receives the code scanning signal from the temperature measurement detecting module 30 through the second communication receiving pin RX2, the current health code type is confirmed according to the code scanning signal, if the health code is a green code, a high-level signal is output through the green light control terminal G, so that the second switching tube Q2 is in a conducting state to light the green light G-LED, and the red code and the yellow code are the same. It can be understood that the main control chip can also output a corresponding driving signal through a corresponding lamp control end after confirming the health code, so that the LED lamp with the corresponding color flashes and emits light. For example, for the health code of the red code, the driving signal controls the red LED lamp to be in a light emitting state for 1S within 2S, and to be in a non-light emitting state for 1S, and to be sequentially cycled. If the current health code indicates that the user is not just a red code or positive, the main controller 20 may also output a corresponding driving signal to increase the blinking frequency of the red LED lamp.
