Ultraviolet sterilizing device and system using UV LED and method of operating the same {Apparatus and system for sterilizing using UV LED and method of operating the same}

The present invention relates to sterilization of bacteria and viruses using ultraviolet light, and more specifically, to an ultraviolet sterilization device using UV LED and a method of operating the same.

It is known that ultraviolet rays are harmful to the human body when exposed directly to the human body for a long period of time, and are especially harmful to the eyes and skin. The ultraviolet band is divided into UVA, UVB, and UVC bands depending on the wavelength. The UV bands where direct bacterial sterilization effect and virus inactivation performance can be expected are the UVB and UVC bands.

Sunlight on the Earth's surface consists of 44% visible light, 3% ultraviolet rays, and the remainder is infrared. In the vacuum of the Earth's upper atmosphere, sunlight consists of 50% infrared rays, 40% visible rays, and 10% ultraviolet rays. The atmosphere blocks about 77% of solar ultraviolet rays, with almost all of the shorter wavelength ultraviolet rays being blocked. 95% of the ultraviolet rays that reach the earth's surface are UVA, the remainder is UVB, and UVC does not exist in the natural environment.

Figure 1 shows the wavelengths of ultraviolet rays/visible rays/infrared rays, and Figure 2 shows the sterilization effect by wavelength in the ultraviolet rays. Looking at ultraviolet light application technology, ultraviolet rays were discovered in 1801, the bacterial sterilizing effect of ultraviolet rays was discovered in 1878, and the wavelength effective for sterilizing was confirmed in 1903. And in 1960, the sterilization effect and principle targeting DNA were proven.

In 1901, an ultraviolet lamp using mercury was first developed, making it possible to artificially produce and utilize ultraviolet rays, and was widely used in various fields because it could be easily implemented at low cost. In 2000, thanks to the development of semiconductor technology, UV LED technology, which can produce only a single wavelength, began to be commercialized. UV LED technology began to be commercialized starting with UVA, which is relatively easy to implement, and recently UVC, which can be expected to have a sterilizing effect, has been commercialized. And because the harmful effects of mercury are serious, the Minamata Convention banning the production/import/import of mercury products after 2020 came into effect in August 2017, and Korea signed the convention in 2014 and passed ratification by the National Assembly in 2019.

Factors directly proportional to the sterilization/inactivation effect on bacteria/virus targets include the UV intensity of the ultraviolet ray output device, and factors inversely proportional to the sterilization/inactivation effect include the distance between the ultraviolet sterilization device and the sterilization target and the ultraviolet irradiation time. . The total cumulative amount of ultraviolet irradiation per unit area depending on the correlation between ultraviolet ray intensity, the distance between the ultraviolet sterilizing device and the sterilizing object, and the ultraviolet irradiation time varies depending on the bacteria/virus subject to sterilization/inactivation.

However, since ultraviolet wavelengths are not in the visible light band, users cannot directly check them with the naked eye. Therefore, there is a problem in that it is not possible to intuitively immediately determine whether the user may suffer damage due to direct exposure to ultraviolet rays when the ultraviolet sterilization device is operating.

UV LED chips are supplied with power and provide ultraviolet rays in the target wavelength range, but at this time, the light conversion efficiency is very low compared to general cases such as lighting LEDs, so only a portion of the supplied energy is converted into ultraviolet rays and most of the rest is converted into heat energy. Because of the conversion, heat generation is severe, and especially in the case of high-output chips, the degree of heat generation becomes more severe. When a UV LED sterilization device is implemented in a conventional way, as the temperature rises due to high heat, the UV light conversion efficiency further decreases, and the sterilization performance deteriorates. If sensors are placed close to the ultraviolet ray output element inside the sterilization device, it is common. There is a problem that the risk of sensing information collected becoming inaccurate or malfunctioning compared to room temperature increases.

In addition, when the ultraviolet sterilization device is made in a closed type (box type), the sterilization area and ultraviolet irradiation distance are determined in advance, so the ultraviolet irradiation time can be determined in advance based on the total cumulative amount of ultraviolet irradiation per unit area, but the ultraviolet sterilization device When making it open, there is a problem that the UV irradiation time cannot be determined in advance because the sterilization target area and irradiation distance are unspecified.

In addition, when using a combination of an existing proximity sensor and a motion sensor, or when using a motion sensor with a distance measurement function, even if the target sterilization area and irradiation distance information are obtained and the ultraviolet irradiation time required for sterilization is arbitrarily designated, most Since it is not possible to provide a perfect LoS (Line of Sight) from the sterilization device to the sterilization target in the real environment, for example, if an obstacle (general object, not a person) exists in the middle, the target sterilization area and irradiation distance are misjudged and sterilization is completed. There is a problem of performing an incomplete sterilization operation by performing an irradiation time that is less than the required irradiation time.

It may include a control unit that reports to the server, stops UV irradiation when movement information is received from the motion sensor, and performs a sterilization operation using ultraviolet rays if there is no movement information for a certain period of time.

It can be created as a gobo pattern that the user can check.

The UV FoV guideline formed through the axicon lens is wider than the UV effective FoV of the ultraviolet ray output device, and the motion sensor FoV formed by the motion sensor is wider than the UV FoV guideline. The diffusely projected gobo pattern formed through the convex lens is wider than the UV effective FoV of the ultraviolet ray output device, and the motion sensor FoV formed by the motion sensor is wider than the diffusely projected gobo pattern. The ultraviolet ray output device is mounted on a separate MI-PCB (Metal Insert PCB) separate from the tilt sensor, magnetic sensor, and motion sensor.

An ultraviolet sterilization system using UV LED according to the present invention for achieving the above technical problem includes an ultraviolet sterilizing device that sterilizes a predetermined area using ultraviolet rays; and providing environmental information collected from the ultraviolet sterilization device to the user, setting a sterilization/inactivation policy for bacteria/viruses using the ultraviolet ray irradiation time, irradiation area, or irradiation distance entered by the user, and setting the policy information set above. It includes an app or server (app/server) of an external terminal that transmits a control command including output device; a tilt sensor that collects irradiation angle information of the ultraviolet ray output device; A magnetic sensor that detects the strength of a magnetic field generated from a magnetic element included in an accessory including an auxiliary shade and support installed in the ultraviolet ray output device; At least one motion sensor that acquires the shortest distance to the sterilization target area through sensing, acquires installation environment data within the detection range, and detects the ultraviolet irradiation range and movement around the ultraviolet irradiation range; and notifies the app/server of the ultraviolet ray irradiation time of the ultraviolet ray output device, analyzes the irradiation angle information of the ultraviolet ray output device collected from the tilt sensor, and performs ultraviolet ray operation when the ultraviolet ray irradiation direction is outside the preset effective angle range. blocks, transmits ultraviolet ray blocking information to the app/server, reports to the app/server whether the ultraviolet sterilizing device is combined with the appendage using the strength of the magnetic field detected by the magnetic sensor, and It includes a control unit that stops irradiating ultraviolet (UV) rays when motion information is received from the sensor and performs a sterilization operation using ultraviolet rays if there is no motion information for a certain period of time.

If the control command received from the app/server is an irradiation time, the ultraviolet sterilizing device performs a sterilization operation by reflecting the irradiation time, and if the control command received from the app/server is an irradiation distance or irradiation area, It is characterized by performing a sterilization operation by deriving pre-mapped irradiation time information.

The method of operating an ultraviolet sterilization system using a UV LED according to the present invention to achieve the above technical problem includes an ultraviolet sterilizing device having a tilt sensor, a magnetic sensor, a motion sensor, and a communication unit, and an app on an external terminal that communicates with the ultraviolet sterilizing device. In the method of operating an ultraviolet sterilization system including a server (app/server), the ultraviolet sterilization device checks whether the tilt sensor, magnetic sensor, motion sensor, and communication unit are operating normally and performs ultraviolet ray output preparation (UV ready). step; The app/server acquiring ultraviolet ray irradiation time information from the ultraviolet sterilizing device; Checking the effective angle range of the ultraviolet sterilizing device; Checking whether the ultraviolet sterilizing device is coupled to the accessory; Obtaining environmental data within the detection range of the motion sensor by performing a learning mode in which the motion sensor analyzes an installation environment within the detection range; The app/server receives the ultraviolet ray irradiation time information, the effective angle range check information of the ultraviolet sterilizing device, the combination check information of the ultraviolet sterilizing device and its accessories, and environmental data within the detection range of the motion sensor and provides them to the user.

Checking the effective angle range of the ultraviolet sterilizing device can be done by analyzing the angle information of the ultraviolet sterilizing device collected by the tilt sensor to determine whether the ultraviolet irradiation direction of the ultraviolet sterilizing device is outside a predefined effective angle range. there is.

Whether the ultraviolet sterilizing device is combined with the accessory is determined by whether the magnetic sensor detects the magnetic field intensity generated from neodymium contained in the accessory of the ultraviolet sterilizing device and whether the magnetic field intensity is outside a preset effective range. This can be done through.

In the step of performing sterilization corresponding to the control command, if the control command includes irradiation time information, the ultraviolet sterilizing device performs a sterilization operation corresponding to the irradiation time, and the control command is irradiated with the irradiation distance or irradiation area. If the information is included, the ultraviolet sterilization device can perform a sterilization operation by deriving pre-mapped irradiation time information.

According to the ultraviolet sterilization device and system using UV LED and its operating method according to the present invention, not only the UV irradiation range but also the surrounding area is used by using a motion sensor that detects a wider FoV than the UV FoV (Field of View). When movement is detected, UV irradiation is immediately stopped, and if no movement is detected for a certain period of time, it is judged to be in a safe state and UV sterilization is performed, thereby preventing the human body from being exposed to ultraviolet rays.

According to the present invention, it is possible to check the UV effective FoV (Field of View, UV irradiation range) at the stage of designing and measuring the ultraviolet irradiation area in a sterilization device equipped with a UV output element, and the UV output element, filter, and special lens are used. By providing guidelines to visually check the UV irradiation range by configuring the UV effective FoV at the same angle or at a slightly wider angle including the safety margin, users can know information about not being exposed to UV rays and can view the UV sterilizing device more effectively. It can be used safely.

In addition, according to the present invention, by separating the ultraviolet ray output device into a separate PCB and applying MI-PCB (Metal Insert-PCB) capable of responding to high heat, ultraviolet rays are sterilized by high heat generated structurally due to the limit of the light conversion efficiency of UV LED. It can prevent deterioration of the sterilization performance of the device, prevent incomplete operation of key elements such as sensors mounted on the sterilization device, and improve the quality of the sterilization device.

In addition, according to the present invention, in order to solve the conventional structural problem that the ultraviolet ray irradiation time cannot be determined in advance because the sterilization target area and irradiation distance are unspecified in the open ultraviolet sterilization device, the sterilization target/irradiation time is not determined in advance through one or more sensors. By conducting environmental analysis such as area, and the sterilization device itself analyzes the collected raw data and reflects the user's sterilization/inactivation policy through app/server linkage, unnecessary power consumption is achieved even in various environments where the sterilization target/area is unspecified. Sterilization/inactivation operations can be carried out efficiently and accurately without any sterilization.

Figure 4 is a block diagram showing the configuration of an ultraviolet sterilization system using UV LED according to an embodiment of the present invention. Referring to FIG. 4, the ultraviolet sterilization system using UV LED according to an embodiment of the present invention includes an ultraviolet sterilizing device 40 and an app or server 45 (hereinafter referred to as app/server) of an external terminal. .

It receives control commands from and sterilizes by irradiating ultraviolet rays according to the control commands. The app/server 45 provides environmental information collected from the ultraviolet sterilizing device 40 to the user, and uses the ultraviolet ray irradiation time, irradiation area, or irradiation distance entered by the user to implement a sterilization/inactivation policy for bacteria/viruses. is set, and a control command containing the set policy information is transmitted to the ultraviolet sterilizing device 45.

When the control command received from the app/server 45 is an irradiation time, the ultraviolet sterilizing device 40 performs a sterilization operation by reflecting the irradiation time, and the control command received from the app/server 45 is set to the irradiation distance. Alternatively, in the case of an irradiation area, the sterilization operation can be performed by deriving pre-mapped irradiation time information.

The ultraviolet sterilizing device 40 includes an ultraviolet ray output device 410, a tilt sensor 420, a magnetic sensor 430, at least one motion sensor 440, a control unit 450, and a communication unit 455, It may further include a laser output device 460 and an axicon lens (Axicon lens, 470).

The ultraviolet rays output device 410 outputs ultraviolet rays at a predetermined irradiation angle (Field of View, FoV). Figure 6 shows the radiation characteristics of the ultraviolet ray output device 410. Referring to FIG. 6, the ultraviolet ray output device 410 has ultraviolet ray irradiation characteristics with a unique FoV (Field of View, irradiation angle) range for each manufacturer/product. Figure 7 shows the final radiation characteristics of the ultraviolet sterilizing device 40 on which the ultraviolet ray output element 410 is mounted. Referring to FIG. 7, the ultraviolet sterilizing device 40 on which the ultraviolet ray output element 410 is mounted may have ultraviolet irradiation characteristics with a UV effective FoV 710 in a range adjusted according to the device design technique and shape.

The tilt sensor 420 collects information on the irradiation angle of the ultraviolet ray output device 410.

The magnetic sensor 430 detects the strength of a magnetic field generated from a magnetic element included in an accessory (not shown) installed on the ultraviolet ray output element 410. The appendages may include auxiliary shades, supports, etc.

At least one motion sensor 440 obtains the shortest distance to the sterilization target area through sensing, obtains installation environment data within the sensing range, and detects the ultraviolet irradiation range and movement around the ultraviolet irradiation range.

The control unit 450 notifies the app/server 45 of the ultraviolet irradiation time of the ultraviolet ray output device 410 and analyzes the irradiation angle information of the ultraviolet ray output device 410 collected by the tilt sensor 420 to determine the direction of ultraviolet irradiation. If it is outside this preset effective angle range, ultraviolet rays are blocked, ultraviolet ray blocking information is transmitted to the app/server 45, and the ultraviolet sterilizing device 40 uses the strength of the magnetic field detected by the magnetic sensor 430. It reports to the app/server 45 whether it is coupled to the appendage, stops UV irradiation when movement information is received from the motion sensor 440, and performs sterilization by ultraviolet rays if there is no movement information for a certain period of time. .

The laser output device 460 is disposed adjacent to the ultraviolet ray output device 410 and outputs a laser beam.

The axicon lens 470 is a laser output element that uses the laser beam output from the laser output element 460 as incident light to form the output light of the laser output element 460 so that the ultraviolet irradiation range of the sterilization device can be recognized with the naked eye. It is placed with (460).

Figure 8 shows the shape of an axicon lens. Referring to FIG. 8, an axicon lens (470) is a special type of lens with a flat entrance surface and a conical exit surface, and can convert an incident bessel beam into a ring-shaped pattern.

By narrowing or widening the apex angle 472 of the axicon lens 470 based on the effective FoV information of the ultraviolet sterilizing device 40, a guideline suitable for the effective FoV of ultraviolet rays can be provided. In other words, the degree of diffusion of the bessel beam can vary depending on how the central apex angle 472 of the cone shape is set. By narrowing the apex angle 472, the diffusion ratio can be increased, and by widening the apex angle 472, the diffusion ratio can be made small. Therefore, if the apex angle 472 of the excicon is designed based on the effective FoV information of the ultraviolet sterilizing device 40, a guideline suitable for the effective FoV of ultraviolet rays can be provided.

Figure 9 shows the creation of a guideline 910 that can be visually confirmed by arranging the laser output element 460 and the axicon lens 470. Referring to FIG. 9, an excicon lens 470 aligned with the UV effective FoV is additionally placed on the laser output element 460 to guide the visual perception of the ultraviolet ray irradiation range of the ultraviolet sterilizing device 40. Line 910 may be provided.

Figure 5 is a block diagram showing the configuration of an ultraviolet sterilization system using UV LED according to another embodiment of the present invention. Referring to FIG. 5, an ultraviolet sterilization system using UV LED according to another embodiment of the present invention includes an ultraviolet sterilizing device 50 and an app/server 45.

The ultraviolet sterilizing device 50 according to another embodiment sterilizes germs, bacteria, viruses, etc. by irradiating ultraviolet rays to a predetermined area, and communicates with the app/server 45 through the communication unit 455, and communicates with the app/server 45 through the communication unit 455. /Receives a control command from the server 45 and sterilizes it by irradiating ultraviolet rays according to the control command. The app/server 45 provides environmental information collected from the ultraviolet sterilizing device 50 to the user, and uses the ultraviolet irradiation time, irradiation area, or irradiation distance entered by the user to implement a sterilization/inactivation policy for bacteria/viruses. is set, and a control command containing the set policy information is transmitted to the ultraviolet sterilizing device 50.

When the control command received from the app/server 45 is an irradiation time, the ultraviolet sterilizing device 50 according to another embodiment of the present invention performs a sterilization operation by reflecting the irradiation time, and the app/server 45 If the control command received from is irradiation distance or irradiation area, sterilization operation can be performed by deriving pre-mapped irradiation time information.

The ultraviolet sterilizing device 50 according to another embodiment includes an ultraviolet ray output element 410, a tilt sensor 420, a magnetic sensor 430, at least one motion sensor 440, and a control unit 450, It may further include a light source element 510, a gobo filter 520, and a convex lens 530.

The ultraviolet ray output device 410, the tilt sensor 420, the magnetic sensor 430, at least one motion sensor 440, and the control unit 450 according to another embodiment of the present invention are the same as those in FIG. 4, so description is omitted. .

The light source element 510 outputs a beam, and the gobo filter 520 is arranged in a circular shape between the light source element 510 and the convex lens 530, and generates the ultraviolet irradiation range in a gobo pattern. do. The convex lens 510 diffusely projects the gobo pattern generated by the gobo filter 520 to create a gobo pattern that the user can check. The convex lens 530 adjusts the diffusion angle of the beam pattern, and the curvature of the lens is determined based on the effective FoV information of the ultraviolet sterilizing device 50.

Figure 10 shows the creation of a guideline 1010 that can be seen with the naked eye by arranging the light element 510, Gobo filter 520, and convex lens 530. Referring to FIG. 10, the diameter of the convex lens 530 can be variably designed to match the shape and size of the light source element 510, and the thickness of the lens determines the actual processability, reliability, and absorption/attenuation rate of the light source. It can be determined variably by taking into consideration. By adjusting the curvature of the lens, the diffusion angle of the final irradiated beam pattern can be adjusted. The curvature of the lens is designed based on the UV effective FoV (710) information of the ultraviolet sterilizing device (40, 50), and a circular Gobo filter (520) is installed between the light source element (510) and the convex lens (530). Once placed, the user can recognize the ultraviolet irradiation range by checking the final diffusely projected Gobo pattern (1010).

Figure 11 shows the UV effective FoV (710), which is the ultraviolet ray irradiation range of the ultraviolet sterilization device that is invisible to the naked eye, and the ultraviolet ray guideline (1110) that can be confirmed with the naked eye. Referring to FIG. 11, an excicon lens 470 aligned with the UV effective FoV 710 is additionally placed on the laser output element 460 disposed adjacent to the ultraviolet ray output element 410, or the light element element 510 and a Gobo filter are added. By adding a convex lens 530 aligned with (520) and the UV effective FoV (710), a guideline (1110) is provided so that the ultraviolet ray irradiation range of the ultraviolet sterilizing device (40, 50) can be recognized with the naked eye.

Figure 12 shows the UV effective FOV, which is the ultraviolet ray irradiation range of the ultraviolet sterilizing device, the ultraviolet irradiation range guideline, and the motion sensor FoV, which is the motion detection area. Referring to FIG. 12, the UV effective FOV 710, which is the ultraviolet irradiation range, is included in the ultraviolet irradiation range guideline 1110, and the ultraviolet irradiation range guideline 1110 is included in the motion sensor FoV 1210, which is the motion detection area. do. For example, the UV FoV guidelines (910, 1110) formed through the axicon lens 470 are wider than the UV effective FoV (710) of the UV output device 410, and the motion formed by the motion sensor 440 The sensor FoV (1210) is wider than the UV FoV guideline (1110). In addition, the diffusely projected gobo patterns 1010 and 1110 formed through the convex lens 530 of FIG. 5 are wider than the UV effective FoV 710 of the ultraviolet ray output device 410, and are formed by the motion sensor 440. The motion sensor FoV (1210) is wider than the diffusely projected gobo patterns (1010, 1110).

Through this, one or more motion sensors 440 that not only include the ultraviolet effective FoV (710) but can also detect the surrounding area are installed to prevent users or pets from approaching the ultraviolet sterilizing device (40, 50). If you do this, you can block ultraviolet irradiation to avoid exposure to ultraviolet rays. Using the motion sensor 440, which detects a wider FoV (1210) than the UV FoV (710), not only the UV irradiation range (710) but also movement around it is detected to immediately stop UV irradiation and prevent movement for a certain period of time. Existing problems can be solved with a safety design plan that prevents the human body from being exposed to ultraviolet rays by performing UV sterilization after entering an undetected safety state.

In addition, when using an existing general motion sensor, if additional supplementary measures are not taken, the possibility of false detection or non-detection of user or pet movement information increases due to changes in the surrounding environment. In other words, if a separate policy is not reflected, movement in areas where ultraviolet rays do not actually reach may be detected and sterilization may not be performed unnecessarily, or more power and time than necessary may be consumed.

Meanwhile, the ultraviolet ray output element 410 of the ultraviolet sterilizing device 40, 50 according to the present invention is a separate MI-PCB (Metal Insert) separated from the tilt sensor 420, magnetic sensor 430, and motion sensor 440. It can be mounted on a PCB). Figure 13 shows the application of a separate MI-PCB to cope with the high heat of the UV LED chip, which is one of the ultraviolet output devices 410, and Figure 14 shows an example of the implementation of a separate MI-PCB to cope with the high heat of the UV LED chip. It represents.

Referring to Figures 13 and 14, the UV LED chip 410 receives power and outputs ultraviolet rays in a target wavelength band. At this time, the light conversion efficiency of the UV LED chip 410 is very low compared to the lighting LED, so only a part of the supplied energy is converted into ultraviolet rays and most of the rest is converted into heat energy, so the UV LED chip 410 generates a lot of heat, especially at high output power. In the case of chips, there is a problem in that the degree of heat generation becomes more severe. In order to improve the high heat problem of the UV LED chip 410, the UV output device 410 can be used with other sensor devices 1330 that are vulnerable to heat generation, such as a tilt sensor 420, a magnetic sensor 430, and a motion sensor ( 440) is mounted on a separate MI-PCB (Metal Insert PCB, 1310) separate from the main PCB (1320) on which it is placed. The main PCB 1320 includes elements 1340 for UV FoV guidelines, for example, the laser output element 460 and axicon laser 470 of FIG. 4 or the light source element 510 of FIG. 5, and a gobo filter ( 520) and a convex lens 530 may be disposed. In this way, the stable ultraviolet output performance of the UV LED element can be maintained through the MI-PCB (1310) in response to high heat, and the accurate operation of the various sensors (420, 430, 440) applied in the ultraviolet sterilizing device (40, 50) can be guaranteed.

Figure 15 shows the ultraviolet sterilizing devices 40 and 50, accessories (auxiliary shade, support), and their combined form. Referring to FIG. 15, (a) shows the shape before the auxiliary shade 1510, which guides the ultraviolet rays irradiated from the ultraviolet sterilization device, and the ultraviolet sterilizing device 1520 are combined, and (b) shows the shape of the auxiliary shade 1510. It shows a shape (1530) in which a and an ultraviolet sterilizing device (1520) are combined. Figure 15 (c) is an example of the shape 1550 in which the ultraviolet sterilizing device 1520, the accessory shade 1510, and the stand-type support 1540 are combined.

Meanwhile, a method of operating an ultraviolet sterilization system using UV LED according to an embodiment of the present invention will be described. Figure 16 is a flowchart showing a method of operating an ultraviolet sterilization system using UV LED according to an embodiment of the present invention.

Referring to FIGS. 4, 5, and 16, first, the ultraviolet sterilizing device (40, 50) checks whether the tilt sensor (420), magnetic sensor (430), motion sensor (440), and communication unit (455) are operating normally. and perform ultraviolet output preparation (UV ready) (step S1610).

The app/server 45 obtains ultraviolet irradiation time information from the ultraviolet sterilizing devices 40 and 50. (Step S1620) Checks the effective angle range of the ultraviolet sterilizing devices 40 and 50. (Step S1630) Ultraviolet sterilization. To check the effective angle range of the devices 40 and 50, the angle information of the ultraviolet sterilizing devices 40 and 50 collected by the tilt sensor 420 is analyzed and the direction of ultraviolet irradiation of the ultraviolet sterilizing devices 40 and 50 is predefined. This can be achieved by determining whether the effective angle is outside the specified range.

Check whether the ultraviolet sterilizing devices 40, 50 are coupled with the accessories (auxiliary shade, support, etc.). (Step S1640) Whether the ultraviolet sterilizing devices 40, 50 are coupled with the accessories is checked by magnetic The sensor 430 detects the magnetic field intensity generated from neodymium included in the accessories of the ultraviolet sterilizing devices 40 and 50 and determines whether the magnetic field intensity exceeds a preset effective range. The motion sensor 440 performs a learning mode that analyzes the installation environment within the detection range to obtain environmental data within the detection range of the motion sensor 440 (step S1650).

The app/server 45 includes the ultraviolet ray irradiation time information, effective angle range check information of the ultraviolet sterilizing device, combination check information of the ultraviolet sterilizing device 40, 50 and the appendage, and environmental data within the detection range of the motion sensor 440. is received and provided to the user, and a control command including the sterilization or inactivation policy of the ultraviolet sterilizing devices 40 and 50 set by the user is transmitted to the ultraviolet sterilizing devices 40 and 50. (Step S1660) The sterilizing devices 40 and 50 receive the control command and perform sterilization corresponding to the control command (step S1670). At this time, if the control command includes irradiation time information, the ultraviolet sterilizing device 40, 50) performs a sterilization operation corresponding to the irradiation time, and when the control command includes irradiation distance or irradiation area information, the ultraviolet sterilizing devices 40, 50 derive pre-mapped irradiation time information and perform a sterilization operation. can be performed.

Figure 17 is a flow chart showing the linkage between the ultraviolet sterilizing devices 40 and 50 and the app/server 45. Referring to FIGS. 4, 5, and 17, safer and more efficient use is possible by eliminating errors or unnecessary operations by providing sensor information applied to the sterilizing device to the user through an interconnection structure between the sterilizing device and the app/server.

The total cumulative amount of ultraviolet irradiation per unit area required to achieve the desired target level of bacterial sterilization and virus inactivation can be secured in advance through demonstration. In order to achieve the total accumulated amount of ultraviolet irradiation per required area, information on the shortest and longest distances between the ultraviolet sterilizing devices 40, 50 and the sterilization target area is obtained, and then the required irradiation time is determined based on the longest distance, which is a condition for deterioration of sterilizing performance. It can be obtained. At this time, the shortest distance information can be obtained from a separate proximity sensor or a motion sensor 440 capable of sensing the proximity distance. The longest distance information can be determined through the correlation between the shortest distance information and the effective FoV of the sterilizing device.

In addition, in order for a separate object or terrain to act as an obstacle between the ultraviolet sterilizing device (40, 50) and the sterilizing target, the sensor can apply an algorithm to post-adjust the information obtained from the sensor to obtain accurate shortest distance information. Separately or in addition, the user can specify the sterilization area through linking with the smartphone app/server 45 or carry out accurate sterilization operation by reflecting the policy of excluding obstacle terrain.

When the ultraviolet sterilization device (40, 50) is operated, it self-checks whether the mounted sensors (420, 430, 440) are operating normally and whether communication with the app/server is possible, and then irradiates the ultraviolet ray that is set to the factory default value. The time is notified to the app/server 45.

By analyzing the angle information of the ultraviolet sterilizing devices (40, 50) collected from the tilt sensor (420) mounted on the ultraviolet sterilizing devices (40, 50), the current ultraviolet irradiation direction of the ultraviolet sterilizing devices (40, 50) is determined from the side. If the effective angle is outside the predefined range, such as when looking at the upper surface, the ultraviolet irradiation operation is blocked in advance and the information is reported to the app/server (45) so that the user can correctly set the ultraviolet sterilizing device (40, 50). Guide.

The magnetic sensor 430 mounted on the ultraviolet sterilizing device 40, 50 measures the strength of the magnetic field generated from magnetic elements such as neodymium included in the accessories of the ultraviolet sterilizing device (shade, stand-type support, wall-mounted support, etc.) It detects and reports to the app/server 45 whether the ultraviolet sterilizing devices 40 and 50 are combined with the appendages. Based on this information, the accuracy of sterilization target/area/distance information can be improved.

It is activated in a variety of ways, such as physical buttons of the ultraviolet sterilizing devices (40, 50), voice recognition, motion recognition, control commands from the app/server (45), and a preset scheduler, so that the motion sensor (440) is installed in the installation environment within the detection range. Proceed with the learning mode to analyze and obtain the corresponding raw data. At this time, if the ultraviolet sterilizing device (40, 50) and the accessory are combined, the raw data can be self-filtered, and regardless of self-filtering, the entire raw data collected or the updated raw data information after filtering can be stored in the app. /Report to server (45).

The app/server 45 provides the collected environmental information to the user through a smartphone app, and the user sets a sterilization/inactivation policy for bacteria/viruses, such as ultraviolet ray irradiation time, irradiation area, or irradiation distance, and this information is It is transmitted as a control command to the ultraviolet sterilizing devices 40 and 50.

When the control command from the app/server 45 comes in the form of irradiation time, the ultraviolet sterilizing device (40. 50) performs sterilization operation by reflecting the relevant policy, and when it comes in the form of irradiation distance or irradiation area, the pre-mapped irradiation is performed. Derive time information and perform sterilization operation.

In the case where the app/server (45) linkage is not considered from the beginning in the installation environment of the ultraviolet sterilizing device (40, 50), or even if the app/server (45) linkage structure is applied in the installation environment, the app/server (45) is not used in the operating environment. ) In cases where linkage is not possible, complementary measures can be implemented in which the ultraviolet sterilizing device (40, 50) independently determines and operates all app/server (45) linkage flows.

Figure 18 is a graph showing raw data sensed in a shape in which an ultraviolet sterilizing device and accessories (auxiliary shade, support) are combined. Referring to FIG. 18, the installation environment raw data within the detection range collected through the learning mode of the motion sensor 440 in a shape in which the ultraviolet sterilization device 40, 50 and the accessories (auxiliary shade, stand-type support) are combined. As information, it shows the signal intensity according to the relative distance with the ultraviolet sterilizing devices 40 and 50. This is a case where five meaningful installation environment information (1810, 1820, 1830, 1840, 1850) are collected, and only the third data (1830) is the information to be measured/judgmented. Data other than the third data (1830) must be filtered through post-processing such as information analysis. This is information.

Figure 19 shows an example of a method of obtaining effective shortest distance information when a medium-area sterilization policy is reflected by the app/server 45. Referring to FIGS. 4, 5, and 19, the x-axis represents distance information between the sterilizing device and the detected object, and the y-axis represents signal strength information generated by the object.

All unnecessary information due to Gaussian noise or multi-path fading can be filtered out in advance through the signal strength reference value for determining regular distance information aligned parallel to the x-axis. Reference number 197 is a small-area sterilization section that is reflected in policy by the app/server 45 and indicates that it is subject to filtering. Reference number 198 is reflected in the policy by the app/server 45 and indicates a valid information section. Reference number 199 indicates that the policy is reflected in the app/server 45 for large-area sterilization and is subject to filtering. Reference number 196 indicates the signal strength standard value for determining regular distance information.

The first data 191 is distance information generated by the accessories (auxiliary shades) of the ultraviolet sterilizing devices 40 and 50, and it can be seen that it is an installation environment combined with the accessories through the magnetic sensor 430, and ultraviolet sterilization Since it is a pattern that occurred in the closest proximity to the device (40, 50), it can be filtered by the device itself, filtered through linkage with the app/server (45), or filtered by the user's policy settings.

The second data 192 is distance information generated by the attachment (stand-type support) of the ultraviolet sterilizing devices 40 and 50, and it can be seen through the magnetic sensor 430 that it is an installation environment combined with the attachment, and the ultraviolet sterilization device 40, 50 is an attachment (stand-type support). Since it is a pattern that occurred in close proximity to the sterilizing device (40, 50), it can be filtered by the device itself, filtered through linkage with the app/server (45), or filtered by the user's policy settings.

The third data 193 is the shortest distance information generated by the sterilization target/area targeted by the ultraviolet sterilizing device 40, 50, and is the installation environment combined with the accessory through the magnetic sensor 430, but the measured distance It is outside the combined arrangement section with the appendage, and because it is above the signal strength standard value, the device does not filter itself, and because it is information within the valid range by app/server (45) linkage and the user's policy settings, it is not filtered and is targeted. It is determined to be a normal value. If there is a plurality of data in this category, the relatively close distance information is due to objects/environments placed in the middle, so the value with the furthest effective distance among the plurality of data is set as the reference value.

The fourth data 145 is the longest distance information generated by the target sterilization target/area of the sterilization device, and is the installation environment combined with the accessory through the magnetic sensor 430, but the measured distance is the information generated by the target sterilization object/area. It is outside the deployment section and is above the signal strength standard value, so it is not filtered by the device itself. It is information that is outside the valid range due to app/server (45) linkage and user policy settings, so it can be filtered.

The fifth data 195 is distance information generated due to overlapping reflection due to multi-pass fading in the installation environment of the ultraviolet sterilizing devices 40 and 50, and is an installation environment combined with an accessory through the magnetic sensor 430, but the signal Since it is below the intensity standard value, it is self-filtered on the device, and because it is information outside the valid range due to app/server (45) linkage and user policy settings, it can be filtered.

The present invention has been described with reference to the embodiments shown in the drawings, but these are merely illustrative, and those skilled in the art will understand that various modifications and other equivalent embodiments are possible therefrom.
