Description

Disinfection gate

The present invention relates to a quarantine gate, and more particularly, by accurately measuring the body temperature of a person entering an access passage, it is possible to easily determine whether or not they are infected with a contagious disease, and automatically spraying a disinfectant solution to the person passing through the access passage to prevent quarantine It is about a quarantine gate that can increase the effectiveness.

Various respiratory infectious diseases are occurring, ranging from severe acute respiratory syndrome (SARS) in 2002, H1N1 influenza A in 2009, Middle East Respiratory Syndrome (MERS) in 2015, and Corona 19 (COVID19) in 2019. Accordingly, the strengthening of the quarantine system along with the individual wearing of a mask is emerging. Although all of the above-mentioned respiratory infections are highly contagious and accompanied by fever at the time of onset, fever symptoms appear even when a common disease, such as a cold, occurs, so it is difficult for the infected person to recognize the fact of infection until they are confirmed. Therefore, it is necessary to measure body temperature when entering public places where many people are crowded, to quickly determine whether or not there is an infection, and to take additional tests or quarantine measures when infection is suspected.

On the other hand, in order to accurately measure body temperature, it is necessary to measure the temperature of the rectum, which has entered more than 6 cm from the anus, but since the method is complicated and cumbersome, the return temperature is usually measured. However, measuring the return temperature for all passers-by in a public place where an unspecified number of people pass has a problem that not only takes a lot of manpower and time, but also causes inconvenience to the passer-by. Accordingly, various devices for measuring and monitoring body temperature using a thermal imaging camera have been proposed, but there is a problem in that the reference temperature changes and the accuracy of the measurement value decreases in an environment in which there is a lot of movement of people and the surrounding environment changes frequently.

Accordingly, there is a need for a quarantine gate that can accurately measure the body temperature of an occupant even in a place where there is a lot of movement of people to easily determine whether or not they are infected with a disease.

Here, the front 10a refers to the side on which the entrant enters based on the moving direction of the entrant, and the rear 10b refers to the side where the entrant exits based on the moving direction of the entrant. It means the side face. That is, a person enters the entrance passage 10c from the front side 10a of the main body 10, passes through the entrance passage 10c, and exits to the rear surface 10b side of the main body 10. More specifically, the body portion 10 includes a first pillar portion 11 and a second pillar portion 12 that are spaced apart from each other with an access passage 10c interposed therebetween, and the first pillar portion 11 and the second pillar portion 11 The lower ends of the two pillars 12 may be vertically fixed to the bottom portion 13, respectively, and the upper ends may be connected to each other as needed. Although the drawing shows that the first pillar part 11 and the second pillar part 12 are connected to each other by the cover part 14 disposed horizontally, the present invention is not limited thereto. The connection structure of the two pillars 12 may be variously modified. For example, an upper end of the first pillar part 11 may extend horizontally toward the second pillar part 12 so that the first pillar part 11 and the second pillar part 12 may be connected to each other, and the second The upper end of the pillar part 12 may extend horizontally toward the first pillar part 11 so that the first pillar part 11 and the second pillar part 12 may be connected to each other.

It is installed side by side, but is rotatably coupled in the vertical direction to measure the infrared rays emitted from the occupants and generate a thermal image (I). The visible light camera 21 and the thermal imaging camera 22 are connected to a step motor, respectively, and can be rotated upwardly or downwardly by 45°. Since the visible light camera 21 and the thermal imaging camera 22 are respectively rotatably coupled to the first pillar part 11 in the vertical direction, the key of the person entering the access passage 10c can be recognized, so that the above-described disinfectant solution The injection unit 50 may be easily operated according to the height of the person entering or leaving.

The black body part 30 is for temperature compensation of the thermal imaging camera 22, which deteriorates accuracy due to a change in the reference value when exposed to an external environment for a long time. ), it is located within the angle of view and can radiate heat at a constant reference temperature. At this time, the reference temperature may be set higher than the temperature of the space in which the body part 10 is installed, and may be about 40°C. Since the reference temperature is set higher than the temperature of the space in which the main body 10 is installed, the heat generated by the black body 30 is not absorbed by the black body 30 in the space in which the main body 10 is installed. It can be easily diffused into the space where the main body 10 is installed. Since the camera module 20 described above is inclined at an angle of about 15° from the first pillar 11 toward the black body 30 , the black body 30 can be located within the field of view of the thermal imaging camera 22 . there is. As the black body unit 30 is located within the field of view of the thermal imaging camera 22, as shown in FIG. 3, the person and the black body unit 30 can be photographed simultaneously on the thermal image I, which results in , the temperature of the thermal imaging camera 22 may be corrected based on the reference temperature emitted by the black body unit 30 in the control unit 40 to be described later.

If necessary, a separate frame (not shown) for supporting the infrared temperature sensor 35 , the PCB board, the temperature control unit 36 , and the power supply device 37 may be installed on the inner surface of the housing 31 , if necessary. there is. The temperature value of the diffusion plate 33 measured by the infrared temperature sensor 35 is transmitted to the temperature controller 36 to be described later through the communication line 35a.

The temperature control unit 36 controls the heater unit 32 by feeding back the temperature values transmitted from the contact temperature sensor 34 and the infrared temperature sensor 35, respectively, and adjusts the inside of the heat dissipation space 31a to a reference temperature. As such, it can operate by receiving power from the power supply device 37 . That is, as shown in FIG. 5 , when the diffusion plate 33 diffuses the heat generated by the heater unit 32 over the entire surface, the contact temperature sensor 34 and the infrared temperature sensor 35 are respectively formed by the diffusion plate. The temperature of (33) is measured and transmitted to the temperature control unit 36, and the temperature control unit 36 controls the operation of the heater unit 32 based on the transmitted temperature value based on the inside of the heat dissipation space 31a. adjust the temperature For example, when the temperature value transmitted from the infrared temperature sensor 35 is lower than the temperature value transmitted from the contact temperature sensor 34 , the temperature control unit 36 increases the amount of heat generated by the heater unit 32 to dissipate heat. The inside of the space 31a may be adjusted to the reference temperature. Conversely, when the temperature value transmitted from the infrared temperature sensor 35 is higher than the temperature value transmitted from the contact temperature sensor 34, the temperature control unit 36 reduces the amount of heat generated by the heater unit 32 to reduce the heat dissipation space ( 31a) The inside can be adjusted to the reference temperature. The temperature control unit 36 controls the heater unit 32 based on the temperature values transmitted from the contact temperature sensor 34 and the infrared temperature sensor 35, respectively, so that the black body unit 30 is always constant at the reference temperature. can dissipate heat.
