The present invention relates to an artificial intelligence quarantine system, and more particularly, to an artificial intelligence quarantine system that is installed in an indoor space used by a large number of people, such as an office or classroom, and automatically recognizes a quarantine target and handles quarantine.

Various infectious diseases, such as SARS, H1N1 influenza, MERS-CoV, and COVID-19, are brought into Korea due to entrants entering Korea from overseas through immigration facilities such as airports and ports. It can be introduced and spread, and the infection can spread exponentially due to direct or indirect contact between people visiting and entering multi-use facilities such as hospitals and churches.

In order to prevent the spread of infection, an indoor space used by a large number of people, for example, an indoor space such as an office or classroom, is disinfected by a professional quarantine company. However, the disinfection work through such a specialized quarantine company is carried out manually by a person carrying disinfection (disinfection) equipment, and a problem that the disinfection work requires a lot of money has been raised.

In addition, since the quarantine work is performed about once a month or two months due to excessive quarantine treatment costs, it is urgent to establish a fundamental and systematic quarantine system.

In addition, workers who perform disinfection work may also be exposed to dangerous viruses, and since only spray-type disinfectant is sprayed, there is a problem that there is a limit to perfect quarantine work.

1 is a conceptual diagram showing the configuration of an artificial intelligence quarantine system according to an embodiment of the present invention, and FIG. 2 is a conceptual diagram showing an object recognition state using a camera according to the present invention.

First, referring to FIGS. 1 and 2, the basic structure of the artificial intelligence quarantine system of the present invention will be described.

The artificial intelligence quarantine system of the present invention can be installed and used in indoor spaces such as offices or classrooms. That is, it is installed in a limited indoor space, recognizes the indoor space and the quarantine object located in the indoor space, and can automatically perform quarantine activities at night when there are no people.

Such an artificial intelligence quarantine system is composed of a detection means 10, a quarantine means 20, a movement guide means 30, and a control unit 40.

The detecting means 10 is configured to detect the shape and size of the inside of the indoor space to be disinfected and the position and size of each of the quarantine objects located in the indoor space. To this end, it may be composed of at least one LIDAR and at least one shooting camera.

LIDAR emits lasers to sense space, analyzes light reflected in space, and combines 3D mapping and localization algorithms to quickly determine space and object information. In addition, LIDAR measures the time and intensity of laser reflection and continuously scans the surroundings, and based on the incoming sensor data, it can map the location of objects while improving the understanding of space. In addition, by periodically updating the corresponding data, it is possible to identify noise by identifying environmental changes such as people moving inside the room or doors opening and closing, and mapping space distance data of LIDAR and object location information data of a shooting camera to be described later Through this, it is possible to accurately determine the distance of an object located in the space.

Referring to FIG. 2 , the camera may recognize an object (ROI) set as a region of interest through image processing in real time through a recognition algorithm, and transmit location information data of the object (disinfection target). In addition, after recognizing the object set as the region of interest, it is possible to calculate the area of the object (desk) and the distance to the quarantine means 20 by returning the corresponding 5 coordinates of the object. At this time, the position information data X1 to X4 corresponding to the five coordinates are position coordinates corresponding to the four corners of the desk, which is an object, and M corresponds to the center coordinate of the desk using a moment.

Based on the information obtained through the sensing means 10, a quarantine object located in the indoor space is identified, and the identified quarantine object is quarantined (disinfected) through the quarantine means 20.

The quarantine means 20 may include a body 21 and a disinfection treatment member 22.

The body 21 is movably coupled along the moving guide means 30 . Since the movement guide means 30 is a path on which the quarantine means 20 is coupled and moves, it is installed corresponding to the path on which the quarantine means 20 moves. For example, the movement guide means 30 may be installed on the ceiling of an indoor space. That is, the movement guide means 30 may be formed in the X-axis longitudinal direction or the Y-axis longitudinal direction at the center of the ceiling of the indoor space. The movement guide means 30 is not limited as long as it is a device capable of moving the body 21, and may be configured as, for example, a rail or an LM guide for movement of a motor pulley.

The body 21 has a structure capable of moving along the above-described moving guide means 30 and moving at the same time.

The disinfection treatment member 22 is coupled to the body 21 and configured to reciprocate in the left and right directions. Although the structure for reciprocating is not limited, since it moves linearly during reciprocating, it is schematically shown, but it can be configured to move in a telescopic manner or coupled to an LM guide to move.

The disinfection means 20, that is, the disinfection treatment member 22 may be composed of an ultraviolet (UV) sterilizing lamp, and may further include a chemical solution spraying means (not shown) for spraying a disinfectant solution used in general quarantine activities. there is. On the other hand, the disinfection treatment member 22 on the drawing can be understood as an ultraviolet sterilization lamp.

In the case of the chemical liquid spraying means, various known technologies can be applied to the structure in which mist is sprayed through the spray nozzle, and the composition position and number of the chemical liquid spraying means can be adopted in various forms depending on the environment of the indoor space to be treated for quarantine. can For example, it is possible to form a plurality of chemical liquid spraying means formed in all directions on the body 21, and spray the antiseptic solution in all directions through the body 21. In addition, a chemical liquid spraying means may be formed on the periphery of the ultraviolet sterilization lamp, and the disinfectant liquid may be sprayed through it.

At this time, the disinfectant supply method for supplying the disinfectant sprayed through the chemical liquid spray means can apply various well-known technologies. and a transfer hose (not shown), or when the body returns to the basic position, it may be configured to be coupled in a docking manner to receive a disinfectant solution.

In addition, the body 21 may be configured to be rotatably coupled. When the body 21 rotates, the rotation angle can be configured to be adjusted, and the rotation angle adjustment can be controlled by the control unit 40 to be described later.

The control unit 40 uses the data acquired through the sensing unit 10 to determine the shape and size of the indoor space and the shape, size, position, etc. of the quarantine object located in the indoor space, and through this, spatial coordinates for the indoor space create a map To this end, the control unit 40 may include a processing unit, a calculation unit, and a storage unit to process data acquired from the LIDAR and the camera. In addition, the control unit 40 controls to disinfect by transferring the quarantine means 20 to the identified quarantine object. That is, as an example for the quarantine means 20 to move, it is possible to control the operation and operation time and speed of the driving motor. In addition, the control unit 40 can control the elevation and elevation of the body 21 and control the left and right reciprocating movement of the disinfection treatment member 22 .

The controller 40 can be installed inside the body 21 or on the ceiling of an indoor space or on a floor or wall of an indoor space, and it is not desirable to limit the number and location of the controller.

3 to 6 are conceptual diagrams showing the state in which the artificial intelligence quarantine system of the present invention is applied to the classroom, FIG. 7 is a diagram showing the quarantine algorithm according to the present invention, and FIG. 8 is a work using the quarantine means applied to the present invention. It is a diagram showing the quarantine order according to the embodiment.

3 to 6, the moving guide means 30 is installed in the center of the ceiling of the classroom in the longitudinal direction of the indoor space, and the quarantine means 20 can move along the moving guide means 30. . If the classroom area is large, a plurality of moving guide means 30 are installed at regular intervals, and a quarantine means 20 composed of a body 21 and a disinfecting member 22 is configured in each moving guide means 30. You may.

Referring to FIG. 7 , first, the control unit 40 receives an image of a classroom captured by a camera installed in the classroom, and returns object location coordinates through object recognition using image processing.

In addition, although not shown in detail, classroom space mapping is performed through LIDAR installed in the classroom, and an open distance within the space is calculated and transmitted to the control unit 40. The control unit 40 collects the aforementioned object location information through a photographing camera and LIDAR. Since the above-described operation is configured to be performed at regular intervals, it is possible to grasp the moving state of an object to be disinfected in an indoor space such as a classroom every moment, and to determine the presence or absence of a person in the indoor space and use it as quarantine processing information. That is, it can be configured to perform disinfection processing during the night time zone when there are no people rather than the time zone when there are people. In addition, since the object to be quarantined, such as a desk (reference numeral not shown), is not a fixed location, and its location may change every moment, the quarantine means ( 20) can be used as movement information and quarantine processing information.

Then, the control unit 40 transfers the quarantine means 20 to the collected object, that is, the place where the quarantine object is located, using the collected object location information. The control unit 40 calculates the distance between a quarantine object such as a desk and the quarantine means 20 in advance and transfers the quarantine means 20 according to the calculated value. That is, the body 21 moves along the moving guide means 30 according to the value calculated by the control unit 40 and then descends. After descending to the predetermined position, the disinfection treatment member 22 moves in the left and right directions. After the disinfection treatment member 22 moves in the left and right directions to a set position, an ultraviolet (UV) sterilization lamp is irradiated onto the desk to perform a disinfection operation. At this time, the disinfectant solution can be sprayed together to further improve the quarantine efficiency.

On the other hand, when disinfecting desks in classrooms using the quarantine means 20, it can proceed as shown in FIG. 8.

That is, the control unit 40 can irradiate the ultraviolet sterilization lamp through the location information data obtained through the photographing camera and lidar, and according to the moving speed of the body 21 or the object distance according to the presence or absence of the object (Desk), the ultraviolet rays The irradiation intensity of the germicidal lamp may be adjusted.

First, as shown in (1) of FIG. 8, when 'Desk1' and 'Desk2' are located in the same row, the ultraviolet sterilization lamp irradiation proceeds at the same time, and when passing through the location of the desk, the body 21 slowly (Slos) It moves, and when passing through a place where there is no desk, the body 21 can be set to pass quickly.

Next, when 'Desk1' and 'Desk2' are staggered as shown in (2) of FIG. 8, the control unit 40 controls the ultraviolet germicidal lamp to irradiate UV light from the desk to be faced first and proceed sequentially, This can also be set so that the body 21 moves slowly (Slos) when passing through a place where the desk is located, and so that the body 21 passes quickly (Fast) when passing through a place where there is no desk.

According to the present invention described above, the indoor space is 3D mapped through a sensing means such as a LIDAR and a camera, and the object to be quarantined and its location are identified and the quarantine operation is automatically performed, greatly increasing the convenience of quarantine. It can be improved, and since the object to be disinfected in the indoor space is identified through the sensing means, it is possible to easily identify and treat the disinfection treatment even when the location of the object to be disinfected is changed, especially in an indoor space such as a classroom where only desks and chairs are placed can be useful In addition, since a disinfectant disinfectant and an ultraviolet sterilization lamp are used together during disinfection treatment, the efficiency of disinfection treatment can be greatly improved compared to the conventional method in which only disinfectant was used. Since disinfection treatment is possible at night when there are no people regardless of the situation, the efficiency and convenience of use can be further improved.
