As product safety requirements increase, inspections of employees before they enter the work environment are becoming more and more important. The existing access control system is relatively simple, usually by swiping a card to enter. This access control system not only has too few functions, but also has insufficient security, so it relies heavily on security personnel.

But security guards are slow at checking staff and can also make mistakes and get mixed in. In addition, when security personnel measure the body temperature of employees, due to the influence of outdoor temperature, the temperature error of the body surface is large and the temperature measurement is inaccurate.

The fingerprint card puncher 3, the air conditioner 8 and the alcohol spraying device are all electrically connected to the processor. In addition, the processor is also connected in communication with the locker control system.

Example 3

The present embodiment provides a control method for a security access control system, comprising the following steps:

S1. Set the temperature value and working time of the air conditioner, the processor automatically turns on the air conditioner during the working time, and inputs the set temperature value to the air conditioner.

S2. Enter the fingerprint information of all employees in the fingerprint database of the processor. And the processor stores standard pictures of items that can be carried at work (such as mobile phones), and sets a body temperature threshold (such as 37.5 ℃).

S3. When an employee needs to perform security check, input the fingerprint information in the fingerprint card reader, the fingerprint card reader uploads the fingerprint information to the processor, and the processor determines whether there is a matching fingerprint in the fingerprint database. If there is, it means that the person is an employee. Control the opening of the first automatic door. If the fingerprint information does not match the pre-stored fingerprint, it will prompt an invalid fingerprint.

S4. When the employee enters the testing room, first start the X-ray machine to collect human body image information. Since the position and viewing angle of the X-ray machine remain unchanged, and there is a fixed standing area for personnel in the testing room. Therefore, the height of the human body can be calculated according to the proportion of the height of the human body in the height of the overall image in the human body image information. In this embodiment, the temperature measurement point is set to the forehead, so the height of the temperature measurement point can be calculated according to the height of the human body (the height of the human body − 5cm). Assuming that the height of the temperature measurement point is 160cm, and the height of the last temperature measurement record is 180cm, then control the robotic arm to move down 20cm, and the infrared thermometer can automatically collect the forehead temperature.

In addition, all the pictures of the items carried by the person are extracted from the human body image information, and the similarity between the pictures of the objects and the pre-stored standard pictures is calculated by using the Euclidean distance. Then it is determined that the inspector has carried irrelevant items.

It is judged whether the collected forehead temperature exceeds 37.5 ℃. If it exceeds, it is judged that the person has a high fever.

S5. If the person does not carry irrelevant items and the body temperature is normal in step S4, the second automatic door is controlled to open. In this embodiment, the first automatic door and the second automatic door are automatically closed 10s after they are opened. If the person carries irrelevant items (such as food) or has a high fever, the first automatic door is controlled to open and the voice prompter is controlled to issue a no-passing prompt.

If the person carries irrelevant items (such as food), but the body temperature is normal, the first automatic door is controlled to open and the voice prompter is controlled to issue a no-passing prompt. The processor sends an application request to the locker control system, and at the same time, the processor retrieves the corresponding employee contact information from the employee information database according to the fingerprint information entered by the employee, and contacts the counter information and verification code returned by the locker control system according to the employee contact information. The method is sent to the employee terminal (mobile phone). After the staff has deposited the items, they can go through the security check again.

Every time someone enters the testing room and leaves the testing room, control the alcohol spraying device to spray alcohol to disinfect the testing room.

Although the present invention has been described in detail in conjunction with the preferred embodiments with reference to the accompanying drawings, the present invention is not limited thereto. Without departing from the spirit and essence of the present invention, those of ordinary skill in the art can make various equivalent modifications or substitutions to the embodiments of the present invention, and these modifications or substitutions should all fall within the scope of the present invention/any Those skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included within the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
