Description

An integrated quarantine system for the establishment of Corona Virus Disease-19-freezone via photo-bactericidal treatment, and related systems using the same}

The present invention relates to a light sterilization integrated prevention system for securing a corona-19-free zone.

As a medical light source, the light of deep ultraviolet (Far-UV) or ultraviolet-C can effectively eradicate viruses, bacteria or bacteria. Therefore, using such high-energy deep ultraviolet or ultraviolet-C can eradicate harmful viruses that are currently suffering mankind, so it becomes a very useful light source. For this reason, UV-C light sources are widely used as medical products, and the demand for medical light sources is rapidly increasing with the outbreak of a new virus. However, the currently commercialized UV-C light source is a low-pressure mercury lamp that requires high voltage discharge, contains harmful mercury, and is a vacuum tube product finished with a quartz glass tube, so there are many restrictions on use. Accordingly, we are looking for alternative light sources that can overcome the limitations of low-pressure-mercury lamps.

As an alternative light source, the UV-C LED light source is attracting attention. However, the efficiency of the UV-C LED light source is only 5 to 10% of that of the general lighting LED light source. Due to these limitations of UV-C LED light source technology, the current level of UV-C LED light source technology is still in the research and development stage. To overcome this, global companies are turning their eyes to the development of UV-A LED light source, which has relatively weak sterilization power compared to UV-C, but has similar sterilization power when irradiated for a long time. In other words, the solution is being searched for in the UV-A LED in the 380-420 nm region, which is harmless to the human body and has sterilization power. In addition, when this light emission band is used as lighting, ultra-high color rendering properties are secured, making it possible to develop medical lighting devices with artificial solar performance. In this case, since the characteristic of UV-A exists in the light source, the sterilization characteristic is naturally exhibited.

On the other hand, when high energy ultraviolet rays are applied for medical purposes, they can not only sterilize viruses and bacteria, but also damage humans and surrounding living things. Therefore, it is an urgent reality to develop a new medical lighting technology that can selectively destroy only viruses or bacteria without harming the human body. This technology is the core of light sterilization integrated prevention technology. The technology is achieved when a light sensing device, a light control module, and a light sterilization clinical trial are implemented in an integrated way, through which the Corona-19-free zone information is extracted and documented. Currently, limited sterilization information using various UV-C or UV-A is known, but the light sterilization integrated prevention system proposed in the present invention is not known. The technique compared with the technique proposed in the present invention will be a chemical sterilization method, but it should be remembered that the chemical sterilization method inevitably uses all of the chemicals that are highly toxic to the human body. Since there are health and safety risks depending on the frequency of chemical use, light sterilization is very advantageous for wide-area quarantine. However, this light sterilization method is also introduced only as a light source technology, so it is difficult to apply it extensively. Therefore, in order to graft the preemptive light sterilization method into the quarantine system, extensive light sterilization epidemiologic investigation should be preceded. In other words, there is currently no known technology with an added function to thoroughly control conditions harmful to the human body.

The light sterilization unit 110, for example, is installed on a desk in the room as in the indoor space of FIG. In addition, it is installed in an indoor space in various ways to sterilize desks, chairs, blackboards, computers, lights, etc. installed inside.

The light sensing unit 120 controls the lighting of each LED light source of the light sterilizing unit 110 based on the measured value by measuring the changed environmental information in the indoor space where the light sterilizing unit 110 is installed.

The individual blinking control module 131 is a device that controls each LED light source corresponding thereto to be operated based on each measurement value measured by the light sensing unit 120. In particular, in addition to turning on/off each type of LED light source, each LED The number of lights is also adjusted so that it can be selectively controlled according to the measured value.

For example, a light sterilization unit 110 composed of a UV-C LED light source 111 , a UV-A LED light source 112 and an ultra-high color rendering LED light source 113 is installed in the upper part of the indoor space, and the light sensing unit Assume that the measured value is not received at 120 and all LEDs are turned on and ultraviolet light is being irradiated, and when the human body detection device detects the approach of the human body to the indoor space, the detected value can be transmitted to the light control unit 130. have. The light control unit 130 stops the supply of power to the UV-C LED light source 111 and the UV-A LED light source 112 according to the human body detection signal, so that the human body approaching the room is not exposed to ultraviolet rays.

6 is a diagram illustrating the cumulative counting number of human body detections for each time zone in a predetermined area as an average value for one week according to an embodiment of the present invention.

According to an embodiment of the present invention, the human body detection value sensed by the human body sensing device 121 for each space is transmitted to the optical control unit 130, and the optical control unit 130 transmits the time value at which the detection signal is transmitted for each space. create The time value thus generated is cumulatively counted for each time zone by the optical controller 130 and is generated as a history information table counted for 24 hours.

As shown in FIG. 6 , in the indoor space, the accumulated and aggregated value of human body detection is generated from 9:00 am to 8:00 pm, and it is not detected from 9:00 pm to 8:00 am, and the accumulated and aggregated value for human detection is generated again from 9:00 am can be known

Based on the table generated in this way, the operation of each LED light source of the light sterilization unit 110 is controlled.

In other words, if the lighting reference value of the UV-C LED light source 111 and the UV-A LED light source 112 in the auto-flicker control module 132 is set to be less than the accumulated value of 1, in the case of an indoor space, from 9:00 am At 8 pm, the UV-C LED light source 111 and the UV-A LED light source 112 may be controlled to be automatically turned on.

In addition, referring to FIG. 6 , the accumulated and aggregated values are updated in real time due to a change in the user's life pattern, etc., so that the control setting can be automatically changed according to the lighting reference value initially set by the user.

In addition, after being automatically controlled by the automatic blinking control module 132 , the user may release the automatic blinking control state and arbitrarily control it as needed by the user-specified control module 133 .

Although the operation relationship of the automatic blinking control module 132 according to human body detection has been described in FIG. 6 , the UV-C LED light source 111 having a sterilization function in the same manner as above by detecting the temperature for each time zone in FIG. 6 is blinking. can also be controlled.

7 is a diagram illustrating temperature measurement values according to a downlight position after installing a human body sensing device and a temperature sensing device in an indoor space in relation to the light sterilization unit and the light sensing unit according to an embodiment of the present invention.

For example, a value detected by the temperature sensing device 123 around a desk in the room is transmitted to the optical control unit 130, and when the temperature value transmitted to the optical control unit 130 is determined to be greater than or equal to a predetermined value, the optical control unit 130 ), the UV-C LED light source 111, the UV-A LED light source 112, and the ultra-high color rendering LED light source 113 are lit more in a certain number than the existing number of lights, so that the temperature around the desk in the room is set previously. Adjust so that it is below a certain value.

In addition, when the temperature value transmitted from the temperature sensing device 123 to the light controller 130 is less than or equal to a certain value, on the contrary, the UV-C LED light source 111 , the UV-A LED light source 112 , and the ultra-high color rendering LED light source 113 . ) to reduce the number of lights to the set number.

In addition, in the case of the light energy sensing unit 122, the UV-C LED light source 111, the UV-A LED light source 112, and the ultra-high color rendering LED light source detect the light of the light source that automatically flickers in places such as the entrance door. The power supply to (113) is stopped, and the ultra-high color rendering LED light source (113) can be maintained.

As described above, the individual blinking control module 131 controls the operation of each LED according to the surrounding environmental conditions detected by the light sensing unit 120, thereby increasing the sterilization efficiency in real time.

The user-designated blinking control module 133 gives priority to a control command arbitrarily designated by the user rather than the influence of the sensed value of the light sensing unit 120 to be controlled. For example, the user-specified control module so that the light sterilization unit 110 is operated for the entire section from the time the user goes to work to the time to leave the office to sterilize and disinfect the desk in the room while the light sterilization unit 110 is installed in the indoor space. When the operation time is set through (133), the control command of the user-specified control module 133 is prioritized to be operated even if other sensing values are transmitted to the light control unit 130 .

The auto-flicker control module 132 determines the time at which the measured value sensed by the light sensing unit 120 is transmitted to the light control unit 130, and counts the signals transmitted from the light sensing unit 120 for each time period. By counting the signals of each sensed value, the accumulated counting number history is identified, and the effective time for which a specific LED light source is turned on is set in a time period formed by a predetermined counting number or more.

Referring to FIG. 7 , as data showing the average value for one week by detecting the cumulative counting number and temperature value for each time zone in the indoor space, the UV-C LED light source 111 is turned on according to the temperature detection value for each time zone. When the reference value is set to 10 and the excess value of the temperature detection value is set to 20, the UV-C LED light source 111 is automatically turned lights up In particular, when the temperature detection value is 20 or more, the number of lights of the UV-C LED light source 111 lamp can be controlled by the individual blinking control module 131 based on the temperature detection value size.

In addition, when the operation of the light sterilization unit 110 is controlled by the individual blinking control module 131 that considers the human body detection value preferentially over the temperature detection value, the lighting reference value of the UV-C LED light source 111 is based on the temperature detection value. To control the number of lighting of UV-C LED light source 111 lamp for the excess value of temperature detection value only within the time period in which the UV-C LED light source 111 is turned on. can do.

In other words, even if the lighting reference value of the UV-C LED light source 111 according to the humidity value for each time period is set to 10 as shown in FIG. 7 , the UV-C LED light source 111 and UV-A from 9:00 am to 9:00 pm The LED light source 112 is automatically turned on at the same time, and within the operating time of the UV-C LED light source 111, the time period in which the excess value of the temperature detection value is 20 or more is observed at 9 am temperature detection value 35, 4 pm The number of lights of the UV-C LED light source 111 is individually controlled only in the 25 section of the temperature sensing value. For example, until the temperature value is less than 20, the number of lights of the UV-C LED light source 111 is set to 60% of the total number of the UV-A LED light sources 112, and at a temperature value of 20 or more, the number of lights per value greater than 1 is increased. If it is increased by 1%, the number of lighting of the UV-C LED light source 111 at 9 am causes 75% of the total number of the UV-A LED light sources 112 to be turned on, and at 4 pm, 65% of the total number is turned on. control to light up.

In addition, the light control unit 130 generates data on the completion time of sterilization and disinfection according to the lighting of the light sterilization unit 110 in a predetermined space and data on the harmful time in which ultraviolet rays are continuously exposed to the human body and become harmful. This time data is changed according to the number of LED light sources of the light sterilization unit 110 are turned on.

And when the movement of the human body is detected while the UV-C LED light source 111 and the UV-A LED light source 112 of the light sterilization unit 110 are turned on, by comparing the sterilization completion time data and the harmful time data, Control the on-off of the LED lamp.

That is, the light control unit 130 compares the remaining time until the completion of sterilization and the harmful time. When the remaining time is longer than the harmful time, at least one LED light source among the LEDs of the light sterilization unit 110 is turned off so as not to harm the human body.

In the case of turning off the LED light source, the number of lights off according to the degree of harm to the human body may be set again in detail. That is, if the light control unit 130 compares the time information and maintains the lighted state until the time to complete the sterilization, if it is determined that it is harmful, the UV-C LED light source 111 and UV-A LED light source 112 according to the harmful excess time ) to control the number of lights out separately. For example, a hazard class variable according to the type and number of UV-C LED light sources 111 and UV-A LED light sources 112 is generated, and the light-off sequence and number of lights-outs of each lamp are timed compared to the harmful overtime. You can also set each of them individually.

In addition, depending on the environment of the indoor space, an environmental weight may be added to set the number of lights-outs for each type of light source. That is, in the case of a small indoor space, since the increase in temperature is larger, an environmental weight may be applied to reduce the rate at which the UV-C LED light source 111 is turned off.
