Description

Intelligent anti-epidemic gate control

This model relates to a door control system, in particular to an intelligent anti-epidemic door control.

For human beings, the beginning of 2020 is a watershed in the transformation of lifestyles. Due to the raging COVID-19, people's travel patterns have been restricted, and the patterns of studying and working have changed. The severe border blockade has forced many people to shift the focus of life from offline to online. In order for the epidemic to end as soon as possible, in addition to the need for everyone to be protected by the vaccine, personal daily health care management is also indispensable.

In terms of health care management, government agencies and private companies at all levels have implemented a series of epidemic prevention measures. Common epidemic prevention measures are nothing more than wearing masks, monitoring body temperature at any time, making travel records, and maintaining social distancing. Therefore, management personnel are often seen at the entrance of a building to take the body temperature of the visitors and help to leave personal information. If the visitor does not wear a mask, he may be turned away. Because this approach is too costly for human resources, some government agencies will use infrared body temperature detectors instead of manpower to automatically sample the body temperature of visitors. Once the visitor's body temperature is found to be too high, the infrared body temperature detector will issue a warning signal to the visitor and related management personnel for early warning. However, these equipments are very expensive, and not all units can meet their budgets. In addition, if people entering the room are required to wear masks, the infrared body temperature detector does not have the function of distinguishing masks, nor can it warn visitors who do not wear masks or even block them from entering.

On the other hand, after passing the epidemic prevention checkpoint, certain units, such as companies or schools, have the need to attend absentee inspections. Therefore, how to use the same set of epidemic prevention system to complete this part of the demand has become a new focus of market attention.

In order to solve the aforementioned problems, a new type of intelligent epidemic prevention gate control is proposed.

This paragraph of text extracts and compiles certain features of the new model. Other features will be revealed in subsequent paragraphs. Its purpose is to cover the spirit and scope of the additional patent application, various modifications and similar arrangements.

The work host can be further connected with a man-machine interface signal, and receive control commands through the man-machine interface to calibrate the relationship between the image of the heat source and the actual temperature.

Preferably, the passage control device is a smart door lock or a signal control gate.

The work host may further include a large data module, which is connected with the database module information to assist the physical image processing module to determine the image of the visitor and determine whether the visitor is wearing a mask.

Since the infrared camera module can determine whether the visitor has a fever, the camera module can determine whether the visitor is wearing a mask, and then distinguish the identity of the visitor, so that the work host operates the gate control module to perform gate control operations and record the attendance of the logged-in visitor. The new model meets the needs of epidemic prevention monitoring, access control, and absence management in one fell swoop.

The present invention will be described in more detail by referring to the following embodiments.

Please refer to Figure 1 and Figure 2. Figure 1 is a schematic diagram of an intelligent epidemic prevention door control according to an embodiment of the present invention. The intelligent anti-epidemic door control includes an infrared thermal imager module 10, a camera module 20, a work host 30, a door control module 40, a database module 50, a display device 60, and a speaker device 70 And a man-machine interface 80. The functions and types of the aforementioned technical components and the use of intelligent anti-epidemic gate control will be described in detail below.

The infrared thermal imager module 10 can detect the infrared rays emitted by the human body in the environment and form a continuous image of the heat source. In contrast, the camera module 20 is a component used to obtain continuous physical images in the environment, such as a webcam module. As shown in Figure 1, according to the present invention, the camera module 20 has the same camera direction as the infrared camera module 10’s detection direction, so that the approximate range (shown by dotted and dashed lines) under the same viewing angle can be obtained. The image is shown in Fig. 3 (Fig. 3 shows an image captured by the infrared thermal imager module 10 and the camera module 20). In order to facilitate the installation and fixation of the relative positions of the infrared thermal imager module 10 and the camera module 20, the infrared thermal imager module 10 and the camera module 20 can be installed on a tripod 15. In this way, the infrared thermal imager module 10 and the camera module 20 can capture the desired image of a visitor 1. The infrared camera module 10 and the camera module 20 will continuously update different images of the visitor 1 over time to determine whether he can pass through.

The work host 30 is signally connected to the infrared thermal imaging camera module 10 and the camera module 20. It should be noted that if it is connected by a wire signal in Figure 1, it is drawn by a solid line; if it is connected by a wireless signal, it is drawn by a dotted line. The working host 30 can be a computer, or it can be a development board (such as Raspberry Pi or Arduino) installed with necessary hardware. The work host 30 may use an open source operating system such as Linux to operate. If the work host 30 is a computer, one of the important hardware is the communication interface 31, which is the important software and firmware (sometimes including the program software running on the operating system) that connects the work host 30 with external hardware. The final assembly can include hardware such as network cards, connection cables, and wireless communication modules. The following introduces the technical requirements of the intelligent epidemic prevention door control for each module of the work host 30 to utilize or cooperate with the above-mentioned existing equipment of the work host 30 to operate. Therefore, they can be software, including specific code and data, and run in at least part of the hardware framework under the operating system (such as the code and related data files stored in the storage device, in the operating system It is temporarily stored in memory during operation, and is dynamically called and executed by the central processing unit). On the other hand, the modules may also be special hardware, such as application-specific integrated circuits (ASIC) or external cards, to perform the functions assigned by the modules. What's more, these technical requirements can be part of software and part of hardware, and they can be effectively integrated according to the needs of product designers, and they are all within the scope of the technology claimed in this patent.

In addition, the work host 30 also includes a heat source image processing module 32, a physical image processing module 33, a data processing module 34, a gap management module 35, and a large data module 36. The heat source image processing module 32 can determine the body temperature data of a visitor from the heat source images and determine whether the visitor has a fever. The image from the infrared thermal imaging camera module 10 can be shown in FIG. 3, the color with the lower temperature is darker, and as the temperature gradually rises, the highest temperature is displayed in white. The other temperatures between the minimum and maximum temperature are expressed in different color scales (colors). If a fever is defined as exceeding 37.5°C, as long as the color represented by 37.5°C or higher is found on the face, the visitor can be judged as having a fever. In contrast, the physical image processing module 33 can determine the image of the visitor from the physical images and determine whether the visitor is wearing a mask. There are many algorithms for face judgment, which are not limited by the present invention. Please refer to FIG. 3 again, the appearance of the visitor image of the infrared thermal imager module 10 and the camera module 20 are similar. Therefore, the position of the visitor's face determined by the physical image processing module 33 can also be fed back to the heat source image processing module 32 for processing. According to the present invention, the infrared thermal imager module 10 and the camera module 20 can process images of more than one visitor at the same time. Because face recognition can be performed, multiple visitors can be processed separately.

The data processing module 34 can integrate the results of the heat source image processing module 32 and the physical image processing module 33 into a judgment data, edit the physical images with the judgment data in a presentation mode, and output the judgment data and the edited entity image. The judgment data includes the body temperature of the visitor and whether they wear a mask. Please refer to FIG. 4. FIG. 4 shows the edited physical image presented by the display device 60. According to the present invention, the presentation method is as follows: in the physical images, the location of the visitor's face is shown in a box, and the body temperature data of the visitor is displayed at the edge of the box; if the visitor is judged to have no fever and wear a mask , The color of the box and the background color of the visitor’s body temperature data are presented as a first color; if the visitor is judged to be not wearing a mask, the color of the box and the background color of the visitor’s body temperature data are presented as a second color Color presentation; and if the visitor is judged to have a fever, the color of the box and the background color of the visitor's body temperature data are presented in a third color. In this embodiment, the first color is green, the second color is yellow, and the third color is red. It can be seen from Figure 4 that the visitor on the left has a fever, but wears a mask, so a red box is formed on her face. The edge of the red box shows the visitor's body temperature (37.8℃). ; The visitor in the middle does not have a fever and wears a mask, so a green box is formed on her face. The edge of the green box shows the visitor's body temperature (35.5°C) on a green background; the visitor on the right does not have a fever. But he did not wear a mask, so a yellow box was formed on his face, and the edge of the yellow box showed the visitor's yellow background body temperature data (37.3°C). If the visitor on the right puts on the mask, the yellow box will turn into a green box, and he will be allowed to pass by the gate control module 40. Differentiating visitors in different situations by color is helpful for access control management.

The absence management module 35 can determine and record the identity and appearance time of the visitor from the physical images. In other words, once you know who the visitor is, regardless of whether he has a fever or not, his attendance status can be determined. The function of the absence management module 35 is convenient for company attendance or class roll call. The big data module 36 is connected to the database module 50 for information, which can assist the physical image processing module 33 to determine the image of the visitor and determine whether the visitor is wearing a mask. In other words, the big data module 36 is different from the physical image processing module 33 in that the big data module 36 can use the face data stored in the database module 50 to calculate where the visitor’s image is in the physical image and Whether the visitor wears a mask.

The gating module 40 is signally connected to the work host 30 and receives the judgment data. If the judgment data shows that the visitor does not have a fever and wears a mask, the door control module 40 will send an opening signal to an access control device 2 to open the access control device 2; otherwise, send a closing signal to the access control device 2 to Close the passage control device 2. In this embodiment, the gate control module 40 may be a control circuit board, and the channel control device 2 is a signal control signal connected to the control circuit board. In practice, the channel control device 2 can also be a smart door lock.

The database module 50 is connected to the work host 30 and the door control module 40 through the network 3 information, and can store the opening and closing history of the door control module 40, judgment data, the record data of the work host 30, multiple visitor data and each The face image data corresponding to the visitor profile. In this embodiment, the database module 50 is built on a cloud platform. In practice, the database module 50 can also be built in a local storage device.

The display device 60 can receive and display the edited physical images through the network 3. In other words, the image in Figure 4 and even related data can be displayed on a remote device. Although only one display device 60 is shown in this embodiment, according to the present invention, the number can be more than one. In practice, the display device 60 may be a screen, a smart phone or a computer. If it is a smart phone, the edited physical images can be displayed through the APP; if it is a computer, the edited physical images can be displayed in a browser, regardless of the operating system.

The speaker device 70, such as a speaker, is signally connected to the work host 30. The work host 30 can issue a corresponding warning voice based on the judgment data, such as "Classmate, you are not wearing a mask" or "Mr., you have a fever, please see a doctor first". The database module 50 can store a complex array of judgment data and corresponding warning voices. When the loudspeaker device 70 receives the warning voice and can play the warning voice.

The work host 30 is signally connected to the man-machine interface 80, and receives control commands through the man-machine interface 80 to correct the relationship between the image of the heat source and the actual temperature. The man-machine interface 80 may include an input device, such as a keyboard and a mouse, and an output device, such as a screen. The correction method can be used to measure the temperature of a specific area of the face with a thermometer, and use this temperature to define the temperature represented by the color of the corresponding location in the heat source image, and the temperature represented by other colors can be automatically corrected.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, The scope of protection of this new model shall be subject to the scope of the attached patent application.
