Description

Ultraviolet sterilization safe gateway system for human body applying UV optimization driving technology through ultrasonic scanning {ULTRAVIOLET STERILIZATION SAFE GATEWAY SYSTEM BY APPLYING HUMAN BODY USING ULTRAVIOLET OPTIMIZING DRIVING TECHNOLOGY THROUGH ULTRASONIC SCANNING}

The present invention relates to a human body-applied ultraviolet (UV) sterilization safe gateway system, and more specifically, the distance from the side of the visitor to the UV lamp is measured by scanning with ultrasonic waves from the head to the tip of the visitor. Accordingly, by driving so that visible light and UV-C ultraviolet rays are constantly irradiated to the upper and lower part of the accessor, germs and viruses are sterilized harmless to the human body, and the spread of infectious diseases is blocked by removing bacteria and fine dust with high-speed air. And it relates to a human body-applied UV sterilization safe gateway system that can be prevented.

In modern times, as most of life is done indoors, awareness of the importance of the indoor environment is increasing.In particular, since indoor air has a large impact on the human body, air purifiers that purify and supply indoor air are widely used. It is a trend.

However, most air purifiers are simple filtration devices that filter and resupply various impurities contained in indoor air, and have limitations in removing harmful microorganisms such as viruses and bacteria contained in the air. There is a point of inadequate in preventing damage from infection or contamination caused by harmful bacteria of.

Moreover, the need for sterilization and disinfection of air is increasing in places where hygiene must be thoroughly managed, such as hospitals, schools, or restaurants, and thorough preparations are required to provide clean and purified air free from various germs. Actually.

Recently, various viral avian influenza or bacterial infectious diseases have occurred frequently, which threatens the lives of many animals, and some of them have problems of human infection. In preparation for such incidents, various quarantine systems are established and disinfectants are sprayed in areas where infection is expected, but it is not easy to properly defend against the transmission of microorganisms that have already occurred.

For example, coronavirus infection-19, a pandemic disease in Wuhan city in Hubei Province, China, is also known as'Wuhan pneumonia','new coronavirus infection','Corona 19', and is a virus caused by strain. It is a disease.

Initially, it was known only as a respiratory infectious disease of unknown cause, but it is a new type of coronavirus such as SARS (severe acute respiratory syndrome), which was prevalent in 2003, and MERS (MERS, Middle East Respiratory Syndrome), which was prevalent in 2012. It turned out on January 7th.

The World Health Organization (WHO) declared the'International Public Health Emergency (PHEIC)' on January 30 as the coronavirus infection-19 spread to many countries around the world.

Accordingly, prevention is essential because there is no direct treatment method for coronavirus infection-19, and the Centers for Disease Control and Prevention is required to wash and dry hands frequently for at least 30 seconds in running water before and after going out based on the characteristics of this disease that is transmitted through the respiratory tract. It is recommended to wear a hygiene mask when going out to prevent transmission through breathing.

However, microorganisms are small organisms that cannot be observed with the naked eye, and contain fungi, protozoa, bacteria, viruses, algae, etc. to prevent the spread of infection. It is not easy to block. In particular, the spread of bacteria or viruses in places where a lot of people gather, spreads into a national emergency, causing serious economic and social problems.

Meanwhile, one of the things that has been widely used as a means of sterilizing various pathogens including viruses is ultraviolet rays (UV). Ultraviolet (UV) energy has been used to kill bacteria and microbes since the early 1900s. Ultraviolet rays can kill microorganisms very effectively when a sufficient amount of energy is applied, but it is known that the sterilization effect of ultraviolet rays is greatly reduced when the UV level is low and the uniformity of ultraviolet radiation is insufficient.

Conventionally, devices or systems that sterilize indoor air with ultraviolet rays or sterilize appliances or objects with ultraviolet rays have been disclosed, but systems that sterilize and treat bacteria or viruses by direct irradiation of ultraviolet rays to the human body are considered as a problem of the harmfulness of the human body. Its development is insignificant.

In addition, conventionally, an air shower system is installed in a clean room of a semiconductor factory or precision industrial site that requires clean work, and a method to remove fine dust from the operator's body with the force of air and filter it from the filter. Is being used. However, although the air shower is effective in removing fine dust, it cannot remove bacteria or viruses attached to the human body.

Accordingly, there is an urgent need for research and development on a system capable of efficiently sterilizing and treating bacteria and viruses, which are the cause of diseases and diseases, which is a major problem around the world today.

And, Figure 7 is a block diagram of a human body-applied ultraviolet sterilization safe gateway system according to the first embodiment of the present invention.

The ultraviolet sterilization safe gateway system 100 for human body according to the first embodiment of the present invention is a gateway 110, upper and lower human body detection sensors 120 and 121, and voice guidance speakers, as shown in FIGS. 1 to 7. 122, screen monitor 123, operation display unit 124, non-contact hand sensor 125, light-emitting element 130, drive driver 131, light-emitting element 140, drive driver 141, air shower blower (Brower; 150), a memory 160, a wireless communication unit 170, a controller 190, it may be configured to include an ultrasound scanner 220.

First, the ultraviolet sterilization safe gateway system 100 for human body according to the present invention detects the height of the visitor through a non-contact infrared (IR) proximity sensor and selectively irradiates UV ultraviolet rays according to the height of the visitor, but visible light is on the upper part of the visitor. Was configured to sterilize bacteria and viruses by irradiating and irradiating UV-C ultraviolet rays on the lower part of the door. At this time, by scanning from the head to the toe of the visitor through the ultrasound scanner 220, the distance between the side of the person and the light emitting devices 130 and 140 is measured, and the intensity of the visible and UV-C ultraviolet rays is adjusted according to the measurement distance. Visible and UV-C ultraviolet rays were uniformly irradiated to the upper and lower parts of the human body at a constant intensity. In addition, by selectively driving an air shower blower according to the height of the person entering and exiting, it was implemented to block and suppress fine dust and bacteria with high-speed air.

Then, the configuration and operation of the present invention will be described with reference to the accompanying drawings.

The gateway 110 largely includes a first body 111, a second body 112, an upper frame 113, and a moving caster 114.

The first and second bodies 111 and 112 are vertically configured on both sides of the gateway 110 to serve as sidewalls, and are installed in parallel with a predetermined distance with an entrance in the middle. In addition, the upper frame 113 is connected to the upper end of the first and second bodies 111 and 112, and the moving caster 114 is installed at the lower end of the first and second bodies 111 and 112, and the gateway The movement of (110) is made easy.

The upper and lower human body detection sensors 120 and 121 may be configured at both upper and lower sides of the first body 111 and/or the second body 112, respectively, and consist of a non-contact infrared (IR) proximity sensor. Can be.

The upper human body detection sensors 120 installed on both inner and upper sides of the gateway 110 detect a person entering from both directions of the entrance and detect the height of the person. In addition, the lower human body detection sensor 121 installed at the lower inner side of the gateway 110 serves to detect the person entering and the height of the person entering.

For example, when a person entering an adult is detected by both the upper and lower human body detection sensors 120 and 121, when the person is a child or a person with a short height, the upper body detection sensor 120 does not detect the lower body. It is detected only by the detection sensor 121, and the height of the person entering can be detected.

The upper and lower human body detection sensors 120 and 121 may be configured as reflective infrared (IR) proximity sensors. The signal detected by the upper and/or lower human body detection sensors 120 and 121 according to the height of the visitor is used as a control signal to selectively operate the light emitting devices 130 and 140 and the air shower blower 150 .

When a person is detected by the upper and lower human body detection sensors 120 and 121, the voice guidance speaker 122 outputs a voice guide to guide the person to be located in the center. For example, a voice prompt may consist of "start when you stand in the correct position", "start when you stand at a marked point on the floor", and so on.

The screen monitor 123 serves to guide the user of the operation method of the ultraviolet sterilization safe gateway system 100 for human use and to display the current operation state. In addition, the screen monitor 123 includes a function of setting and inputting motion data when configured as a touch screen.

The operation display unit 124 is configured in the front and rear directions of the entrance of the first and/or second body 112, respectively, and displays the operation state by lighting of an LED. For example, the operation display unit 124 may be configured to indicate an operation and a standby state according to the lighting color of the LED by displaying characters such as "SAFE GATEWAY".

The non-contact hand sensor 125 is configured in the direction of the entrance of the first or second body 111, 112 of the gateway 110, and senses the movement of the hand in a non-contact manner, so that the light emitting devices 130 and 140 and the air shower blower ( 150) does not work.

For example, when a person who has passed the gateway 110 passes through the gateway 110 in the opposite direction again, there is no need to receive ultraviolet sterilization and air shower again. In this case, the gateway 110 may be configured so that the light emitting device 130 and 140 and the air shower blower 150 do not operate by recognizing the sensor by touching a hand to the non-contact hand sensor 125 in a non-contact manner. .

Subsequently, the light-emitting elements 130 are vertically arranged to irradiate visible light from four directions on both the inner and upper sides of the first and second bodies 111 and 112 toward the upper center (for example, at an angle of 45 degrees). Can be configured. In this case, the visible light may have an intensity of 400 to 410 nm, and preferably, an intensity of 405 nm. The light emitting device 130 may be composed of a visible light LED having a wavelength of 405 nm.

The light emitting devices 130 may be vertically arranged in four directions toward the center (eg, at an angle of 45 degrees) at both entrances and exits inside the first and second bodies 111 and 112. At this time, the light-emitting device 130 is controlled to be selectively operated according to the height of the person entering and being sensed by the upper and lower human body detection sensors 120 and 121.

For example, when both the upper and lower human body detection sensors 120 and 121 are detected, it is determined as an adult, and all the light emitting devices 130 arranged vertically are operated to transmit ultraviolet rays having a wavelength of 405 nm to the upper part of the person (e.g., head To the waist) for a predetermined time (for example, for 5 seconds) to sterilize bacteria or viruses.

In addition, when the upper human body detection sensor 120 does not detect a human body, but only the lower human body detection sensor 121, the light emitting device is determined as a child or a person with a small height, and is vertically arranged to fit the height of the person entering. Among the 130, it is controlled to operate only the light emitting device 130 having a predetermined height. Accordingly, the UV rays of the wavelength of 405 nm of the light emitting device 130 are irradiated to the upper part of the person (eg, from the head to the waist) for a predetermined time (eg, for 5 seconds) according to the height of the person. Sterilize bacteria and viruses without harming them.

Meanwhile, conventional UV-C lamps mainly use a constant current control method using only safety devices, and harmful ozone (O ₃ ) exceeding in proportion to the constant current output is generated. This has a basic air sterilization effect, but it violates human stability due to the occurrence of exceeding the standard, so an alternative and solution are needed. Therefore, it is necessary to minimize the amount of ozone while there is no ozone generation or satisfies the standard value. To this end, it is urgent to develop a dedicated drive to replace and apply UV-LEDs that are harmless to the human body while satisfying the IEC 62471 recommendation, and the solution of products and the development of original technologies for virus prevention and quarantine actions have recently emerged.

Therefore, in the present invention, a visible light LED module capable of controlling an output of 405 nm was used to sterilize bacteria and viruses.

Next, the light-emitting device 140 is vertical to irradiate UV-C ultraviolet rays from four directions on both the inner and lower sides of the first and second bodies 111 and 112 toward the lower center (for example, at an angle of 45 degrees). It can be configured as an arrangement. In this case, the UV-C ultraviolet rays may have an intensity of 220 to 225 nm, and preferably, an intensity of 222 nm. The light-emitting device 140 may be composed of a UV-C lamp or a UV-LED having a wavelength of 222 nm.

The light-emitting elements 140 may be vertically arranged toward the lower center (eg, at an angle of 45 degrees) in four directions at both entrances and exits inside the first and second bodies 111 and 112. At this time, the light-emitting device 140 is controlled to be selectively operated according to the height of the person who enters the person sensed by the upper and lower human body detection sensors 120 and 121, and the lower part of the person, that is, from the waist to the feet, is controlled for a predetermined time (for example For example, by irradiation for 5 seconds), bacteria or viruses were sterilized without any harm to the human body.

For example, when both the upper and lower human body detection sensors 120 and 121 are detected, it is determined as an adult, and all the light emitting devices 140 arranged vertically are operated so that ultraviolet rays having a wavelength of 222 nm are applied to the lower part of the person (e.g., waist To feet) for a predetermined time (for example, for 5 seconds) to sterilize bacteria or viruses.

In addition, when the upper human body detection sensor 120 does not detect a human body, but only the lower human body detection sensor 121, the light emitting device is determined as a child or a person with a small height, and is vertically arranged to fit the height of the person entering. Among the 140, it is controlled to operate only the light emitting device 140 having a predetermined height. Accordingly, the ultraviolet rays of the wavelength of 222 nm of the light emitting device 140 are irradiated to the lower part of the person (eg, from the waist to the feet) for a predetermined time (eg, for 5 seconds) according to the height of the person. Sterilize bacteria or viruses without any harm.

After the voice guidance is output from the voice guidance speaker 122, the driving drivers 131 and 141 have the operating height of the light emitting devices 130 and 140 according to the height of the person entering according to the detection signal of the upper and lower human body detection sensors 120 and 121. Is selectively driven and controlled.

Subsequently, the ultrasound scanner 220 moves vertically along the ultrasound scanner vertical movement path 230 formed inside the gateway 110 and scans from the head to the toe of the visitor to the side and the light emitting elements 130 and 140 of the visitor. You will measure the distance between them.

At this time, the controller 190 adjusts the intensity of the visible light and UV-C ultraviolet rays according to the measurement distance between the side of the visitor and the light emitting devices 130 and 140 measured through the ultrasound scanner 220, thereby controlling the upper and lower portions of the body of the visitor. It is controlled so that visible light and UV-C ultraviolet rays are uniformly irradiated with a certain intensity.

The air shower blower 150 is arranged vertically at the inner center of the first and second bodies 111 and 112 and is selected according to the height of the visitor according to the detection signal of the upper and lower human body detection sensors 120 and 121 It works as an enemy. The air shower blower 150 functions to remove dust or microorganisms adhering to the body of the visitor by spraying high-speed clean air toward the center for a predetermined period of time.

The air shower blower 150 includes a blower 151, a dust collector 152, and a HEPA filter 153.

When the blower 151 is operated, external air is sucked through the HEPA filter 153, and fine dust and particles contained in the air are filtered and collected in the dust collecting device 52. The clean air that has passed through the HEPA filter 153 is sprayed at high speed through the blower fan of the blower 151 to remove dust or microorganisms attached to the body of the person entering.

UV-C ultraviolet sterilization effect and experimental test results

10 is a schematic diagram showing the sterilization effect of UV-C ultraviolet rays, and FIG. 11 is a graph showing a sterilization effect curve for each wavelength band of UV ultraviolet rays.

Referring to FIG. 10, ultraviolet (UV; ultra violet) is divided into three types of UV-A, UV-B, and UV-C according to the length of the wavelength.

Of these, UV-A is a long-wavelength ray of about 315-400nm, and accounts for about 1% of sunlight. Visible light can reach the dermal layer of the skin, activates the activity of melanocytes, makes the skin black, and causes pigmentation and skin aging. Visible light is used for curing polymers or printing inks, gas measurement, nitrogen element measurement, lighting, optical sensor, image tone measurement ID, counterfeit detection, and sterilization.

In addition, UV-B reaches the base layer of the epidermis or the upper part of the dermis with rays of about 280-315 nm wavelength. UV-B is used in UV curing, optical therapy, optical sensors, image tone measurement, crime analysis, protein analysis, DNA sequencing, and medical devices.

In addition, UV-C is light with a wavelength of 100 to 280 nm, and since the wavelength is short, almost all of it is absorbed by the ozone layer, so the amount that reaches the surface is very small. UV-C is used to kill bacteria, viruses and single-celled tissues due to its strong sterilization properties, and is used for sterilization, air purification, water purification, decontamination of surfaces or water, protein analysis, DNA sequencing, medical devices, and ozone detection.

On the other hand, because ultraviolet rays have great chemical and physiological functions, and strong bleaching functions, pigments and dyes are faded by ultraviolet rays contained in sunlight. These ultraviolet rays have a sterilizing effect, and the sterilizing effect is large within the wavelength range of 150 to 380 nm or 250 to 280 nm, and in particular, ultraviolet rays having a wavelength of 260 to 265 nm destroy the DNA sequence, thereby showing the greatest sterilization effect. 99% of E. coli, diphtheria, and dysentery die when irradiated with UV rays with an intensity of 100 μW per 1 cm2 for 1 minute.

The UV-C lamp (or UV-C LED) emits ultraviolet rays having a wavelength of 100 to 280 nm. This can be 99.9% sterilized within 20 seconds, and has a characteristic that is about 1600 times more effective than sunlight sterilization. In addition, it can be applied to sterilization of all bacterial species, has no resistance to bacteria, has a short time required for sterilization, and easy to use.

As described above, UV-A, UV-B, and UV-C ultraviolet rays have various sterilizing effects, but all of them are harmful to the human body, so they are subject to many regulations and restrictions for application to the human body. However, it has been proven that visible light of a wavelength of 405 nm is harmless to the human body.

In an embodiment of the present invention, a UV-C lamp (or UV-C LED) having a wavelength of 222 nm is used to place the UV-C under the feet with the most bacteria and viruses for a predetermined time (for example, for 5 seconds) among the human body. By irradiating ultraviolet rays, it is implemented so that bacteria and viruses can be sterilized without affecting the human body at all.

In addition, in an embodiment of the present invention, by using a visible light LED having a wavelength of 405 nm harmless to the human body, the visible light is irradiated on the upper part of the body of the visitor for a predetermined time (for example, for 5 seconds), without affecting the human body at all. It was implemented to sterilize bacteria and viruses.

At this time, the UV-C lamp (or UV-C LED) and the visible light LED are controlled to selectively operate according to the height of the person entering and being sensed by the human body sensor 120. That is, the UV-C lamp (or UV-C LED) and the visible light LED are selectively driven according to the height of the person entering and irradiating UV-C and visible light.

The most popular method using ultraviolet rays is the sterilization method using UV-C.

All microorganisms contain nucleic acids (DNA and RNA-transcription) that contain the genetic information of cells, and ultraviolet rays interfere with the binding of adenine and thymine, thereby interfering with reproduction. Because of this, it has the ability to kill almost all types of bacteria and viruses, and is in the spotlight because it kills harmful groups and viruses in a very short time, and is especially useful for sterilizing air and water. Viruses do not have cell membranes, but because they have DNA and RNA, they can also kill viruses by the same effect.

The sterilization effect of ultraviolet rays is related to ultraviolet output and irradiation time, and the survival rate of bacteria decreases almost exponentially with respect to the irradiation amount (ultraviolet intensity x irradiation time), and can be expressed by the following equation.

S=P/PO=e(-Et)/Q

Here, S: survival rate of sterilization, P: sterilization water after irradiation, PO: sterilization water before irradiation, e: radiation intensity of the sterilization line [㎼/㎠], Et: irradiation time (min), Q: survival rate S is 1/e The amount of sterilization radiation required to make it (36.8%) [㎼·min]

If you solve this formula, the strength and irradiation time of the sterilization line become indicators of the sterilization power, and the strength of the sterilization line is again in inverse proportion to the square of the distance between the test object and the sterilization line. If you use these three well, you can do powerful sterilization.

Table 2 below shows the sterilization ability test using UV-C.

UV-C irradiation time was 30 seconds, 12 seconds, 6 seconds, in that order, when irradiated for more than 12 seconds, it was observed that the growth of bacteria was suppressed, and even in the case of irradiation for 6 seconds, the growth rate tended to slow as the incubation time increased. Was observed. And, it was observed that the closer the distance to UV-C in the order of 25cm> 66cm, the higher the growth inhibitory ability of the bacteria.

12 is a photograph showing the results of a sterilization test by irradiating UV-C ultraviolet rays after culturing bacteria in a sample. At this time, UV-C ultraviolet rays used a UV-C LED module with a wavelength of 275 nm, and the sterilization test time showed sterilization results after the initial, 1 minute ± 5 seconds, and 5 minutes ± 10 seconds, E. coli, pneumococcus, yellow It was observed that 99.9% of staphylococcus were sterilized.

13 is a photograph of the test result of testing when bacteria are cultured in a sample and then irradiated with UV-C ultraviolet rays (left) and when not irradiated with ultraviolet rays (right). As can be seen from the photo, bacteria were found in several places in the sample on the right that was not irradiated with ultraviolet rays, and no bacteria were observed in the sample on the left side that was irradiated with UV-C ultraviolet rays.

As described above, the ultraviolet sterilization safe gateway system for human body according to the present invention detects the entry and height of a visitor through a non-contact infrared (IR) proximity sensor, and selectively irradiates UV ultraviolet rays according to the height of the visitor, but the upper part of the visitor Visible light is irradiated to the body and UV-C ultraviolet rays are irradiated to the lower part of the visitor to sterilize bacteria and viruses without any harm to the human body, and the air shower blower 150 is selectively driven to suit the height of the visitor. By blocking and suppressing fine dust and bacteria with air of the present invention, the technical problem of the present invention can be solved.

In addition, the human body-applied ultraviolet sterilization safe gateway system according to the present invention measures the distance from the visitor's side to the ultraviolet light emitting devices 130 and 140 by scanning ultrasonic waves from the head to the toe of the visitor, and then the visible and UV-C ultraviolet rays are applied according to the distance. The technical problem of the present invention is to block and prevent the spread of infectious diseases by driving to uniformly irradiate the upper and lower portions of the visitors to sterilize bacteria and viruses harmlessly to the human body, and by removing bacteria and fine dust with high-speed air. Can be solved.
