Description

Device for disinfection at the entrance}

This invention relates to an entrance quarantine device, in more detail, by automatically aiming at the forehead of a subject to measure heat, not only does not require manpower to measure heat, but also measures heat when there are a large number of subjects. It takes less time and disinfects while preventing waste of the sprayed chemicals by spraying them by misting and spraying the chemicals while passing through the entrance, but by sequentially spraying the body parts in the order of chest, waist, and legs. It relates to an entrance quarantine device that can increase efficiency.

Due to a highly contagious virus such as the coronavirus (COVID-19), strengthening the quarantine system is emerging as an urgent social problem above all.

As such, people such as office work places, business places, work places, meeting places, places of eating or drinking, entertainment places, educational places, places of religious activities, etc. from highly contagious viruses such as coronavirus (COVID-19) or bacteria As a quarantine method to protect this dense space, masking, heating check, hand disinfection, etc. are forcibly or recommended.

Along with this, a technology related to an entrance quarantine device that is installed at the entrance of the space and sprays a sterilizing chemical solution to the entrance and exit is also being studied as a will-hwan for automating the quarantine work on a densely populated space.

As an example of the technology related to the entrance quarantine device as described above, by varying the height of the quarantine device according to the height of the object to be sterilized or actively adjusting the number of operation of the spray nozzles, the chemical solution is evenly distributed over the entire area regardless of the height of the object to be sterilized. It can be sprayed, its structure is simple, and it occupies a small area, so it can be easily moved to other places, and the direction in which the chemical is sprayed can be adjusted according to the sterilization object, and the chemical solution and UV sterilization lamp are simultaneously sterilized. Therefore, it doubles the killing of pathogenic microorganisms, and by installing a heater inside the quarantine device, it is possible to prevent the phenomenon that the chemical liquid is frozen even in cold weather, and improve quarantine efficiency by installing a cover so that the front and rear surfaces of the quarantine device can be sealed with the outside. The technology that can be made has been disclosed in the "Entrance Prevention Device" of Korean Registered Patent Publication No. 10-1676007 (announced on November 14, 2016).

In addition, by easily installing a separate quarantine space at the entrances of buildings such as houses, offices, factories, and public facilities, it is possible to remove taxonomy and viruses from clothes, shoes, and goods without feeling uncomfortable for visitors. By separating the quarantine spaces for visitors and goods, and dividing the quarantine procedures according to the location step by step, it is possible to effectively remove germs and viruses from the visitors and goods as they walk through the quarantine facilities. The technology that can effectively remove bacteria and viruses while preventing the product from being damaged or damaged without feeling that it is the "building entrance" in Korean Patent Application Publication No. 10-2016-0109939 (published on September 21, 2016) It has been disclosed in "Installation Prevention Equipment".

According to the above configuration, the operation of the entrance quarantine device according to an embodiment of the present invention is as follows.

When a human body or an object approaches within a certain speed toward the entrance, the motion detector 10 detects this and wakes up the control unit 20.

The control unit 20 wake-up by the motion detector 10 operates the camera unit 30 to capture a human body or object approaching the entrance, and then transmits the captured image information to the face recognition processing unit 40 Determine whether it is. In the facial recognition processing unit 40, image processing and analysis of whether there is image information corresponding to changes in the shape of the mouth, the shape of the mouth, the shaking of the head left and right, the blinking of the eyes, the shaking of the facial muscles, the shape of the mouth, etc. After determining whether the object is a person, the result is transmitted to the control unit 20.

When it is determined that the object to be photographed is a person, the controller 20 receives the location data of the person's forehead from the face recognition processing unit 40 and controls the solenoid driving unit 50 to control the infrared sensor unit 60 of the infrared sensor. Have (61) aim at the forehead of the person entering,

In the solenoid set 54 of the solenoid driving unit 50, a plurality of electromagnets 542 are installed in a row by vertically and horizontally, so that the magnet 53 is moved vertically and horizontally by changing the magnetic pole and magnetic force of the electromagnet 542. It can be moved, and the orientation coordinates of the infrared sensor 61 linked thereto can be controlled. For example, when coordinates are set to move the magnet 53 by 3 degrees per electromagnet, according to the 3×9 electromagnet arrangement shown in FIG. 7, the orientation coordinates of the infrared sensor 61 are based on the origin. It can be moved ±3 degrees left and right and ±12 degrees vertically.

After aiming at the person's forehead quickly, if the body temperature of the person's forehead is detected through the infrared sensor 61, the control unit 20 determines whether there is a fever symptom that the body temperature of the person is over 37.5 degrees, and generates heat. If there is no symptom, it is notified that access is possible through the display 70, and if there is a fever symptom, the access is denied by displaying it through the display 70.

Visitors who are confirmed to have no fever symptoms through body temperature measurement on their foreheads pass through the injection platform 90 formed in a tunnel shape. In this case, the control unit 20 operates the injection drive unit 120 so that the chemical solution supply unit 100 The chemical liquid (for example, hypochlorous acid water) stored in the chemical liquid tank 102 passes through the transfer pump 130 to the first mist nozzle 91a, the second mist nozzle 92a, and the third spray table 90. It is supplied to the mist nozzle 93a.

The chemical liquid supplied to the first mist nozzle 91a, the second mist nozzle 92a, and the third mist nozzle 93a of the spray table 90 is a first mist nozzle 91a, a second mist nozzle 92a, After being misted by the atomizer 95 inside the third mist nozzle (93a), it is sprayed to the visitor.According to the pace of the person's walking, it is sprayed by sequentially spraying the chest area, the waist area, and the leg area. It is possible to increase disinfection efficiency while preventing waste of the chemical solution.

In addition, the control unit 20 monitors whether the chemical liquid stored in the chemical liquid tank 102 is insufficient through the chemical liquid level sensor 110 installed in the chemical liquid tank 102 of the chemical liquid supply unit 100, and When the chemical liquid stored in 102 is insufficient, it is notified through the display 70 so that the entrance manager can replenish the chemical liquid in the chemical liquid tank 102 in a timely manner.
