Alternatively, it can be sterilized. Further, in the following embodiments, sterilization will be used as an example, but the term "sterilization" can be replaced with "sterilization" or "sterilization".

The ultraviolet irradiation system (400) of the embodiment includes a flying object (101), a determination unit (403), and a control unit (402). The flying object (101) includes an irradiation unit (202) capable of irradiating ultraviolet rays. The determination unit (403) makes a determination regarding the irradiation of ultraviolet rays for each of the one or more irradiation regions based on the situation data indicating the condition of the one or more irradiation regions to be irradiated with the ultraviolet rays. The control unit (402) controls the irradiation of ultraviolet rays from the irradiation unit (202) and the movement of the flying object (101) based on the judgment data including the judgment result of the judgment unit (403). As a result, for example, ultraviolet rays are appropriately irradiated to a portion contaminated by bacteria, viruses, or the like.

The UV irradiation system (400) of the embodiment further comprises a base (302) at which the flying object (101) is anchored. While the flying object (101) is stationary at the base (302), the irradiation unit (202) can irradiate ultraviolet rays. As a result, for example, the ultraviolet rays are appropriately irradiated to the spots contaminated by bacteria and viruses existing in the space of the place (100).

In the ultraviolet irradiation system (400) of the embodiment, the control unit (402) performs aiming for adjusting the attitude of the flying object (101) and the irradiation direction of ultraviolet rays from the irradiation unit (202) with respect to each other. Thereby, for example, even if the attitude of the flying object (101) is disturbed by some factor, the irradiation direction of the ultraviolet rays from the irradiation unit (202) can be kept almost constant.

In the ultraviolet irradiation system (400) of the embodiment, the determination data corresponds to the information indicating the planned irradiation area, which is the area to be irradiated with ultraviolet rays from one or more irradiation areas, and each of the planned irradiation areas.

As a result, for example, in the place (100), the ultraviolet rays are more appropriately irradiated to the contaminated portion by bacteria, viruses and the like.

In the UV irradiation system (400) of the embodiment, the determination data includes information indicating the distance between the flying object (101) and each of the one or more irradiation regions. As a result, the irradiation time of ultraviolet rays is appropriately adjusted according to the distance between the flying object (101) and each of the irradiation regions. Therefore, for example, in the place (100), the ultraviolet rays are more quickly irradiated to the contaminated part by bacteria, viruses and the like.

In the UV irradiation system (400) of the embodiment, the determination data includes simulation results regarding the flight path and UV irradiation time of the flying object (101) that targets the situation of one or more irradiation regions. The control unit (402) controls the flying object based on the flight path and irradiation time of the simulation result. This makes it possible to optimize the flight path of the flying object (101) and the irradiation time of ultraviolet rays. Therefore, for example, in the place (100), the ultraviolet rays are more quickly irradiated to the contaminated part by bacteria, viruses and the like.

In the UV irradiation system (400) of the embodiment, the situation data includes a time history of UV irradiation in each of one or more irradiation regions. Thereby, for example, the determination unit (403) can more appropriately determine the planned irradiation area.

In the ultraviolet irradiation system (400) of the embodiment, the situation data includes a stay history regarding the position and stay time of the resident in each of one or more irradiation areas. Thereby, for example, the determination unit (403) can more appropriately determine the planned irradiation area.

Hereinafter, embodiments will be described with reference to the drawings.

FIG. 1 is a schematic view showing a usage state of the ultraviolet irradiation system according to the embodiment. As shown in FIG. 1, the UV irradiation system according to the embodiment is used, for example, at the place 100. The place 100 is not limited to these, and examples thereof include an office environment, a cafe, a conference room for rent, a family restaurant, a space for rent, and an indoor space. FIG. 1 shows an office environment as an example of location 100.

At the place 100, for example, a user of the place 100 may enter and exit through the door 104, or a table 105 installed at the place 100 may be used for work. In this case, the user at location 100 touches the door 104 to open and close the door 104. Further, the user of the place 100 touches the table 105 while working on the table 105. Bacteria and viruses adhering to the user may adhere to the place touched by the user of the place 100, and the place touched by the user of the place 100 may be contaminated by the bacteria and the virus. Such contaminated areas are preferably sterilized appropriately and promptly. In addition, a place where one or more bacteria, viruses and the like are attached may be a contaminated place, and a place where a predetermined quantity or more of bacteria, a virus and the like are attached per unit area may be a contaminated place.

In one example, as shown in FIG. 1, the flying object 101 moves from the base 102 and irradiates ultraviolet light (UV) to sterilize the contaminated portion 103. The sterilization treatment of the contaminated portion 103 by the flying object 101 is executed in a state where there is no user at the location 100. The contaminated portion 103 is an irradiation area to be irradiated with ultraviolet rays. The degree of sterilization by irradiation of the contaminated portion 103 with ultraviolet rays is generally defined by the ultraviolet intensity (mJ / cm ² ). The ultraviolet intensity (mJ / cm ² ) varies depending on the ultraviolet illuminance (mW / cm ² ) and the ultraviolet irradiation time (s). The ultraviolet illuminance is inversely proportional to the square of the distance between the contaminated portion 103 and the light source. The ultraviolet intensity is a value obtained by multiplying the ultraviolet illuminance by the ultraviolet irradiation time (ultraviolet illuminance × ultraviolet irradiation time). That is, the ultraviolet intensity is proportional to the ultraviolet illuminance and is also proportional to the ultraviolet irradiation time. In the present embodiment, the contaminated portion 103 is irradiated with ultraviolet rays so as to have a predetermined ultraviolet intensity at the contaminated portion 103. Further, as in the example of FIG. 1, when a plurality of contaminated points 103 exist, the flying object 101 moves in the place 100 and irradiates each of the contaminated points 103 with ultraviolet rays. As described above, in the ultraviolet irradiation system according to the present embodiment, the contaminated portion 103 of the place 100 can be appropriately irradiated with ultraviolet rays. Thereby, for example, the contaminated portion 103 is sterilized appropriately and promptly.

FIG. 2 shows an example of a flying object of the ultraviolet irradiation system according to the embodiment. In the present embodiment, as shown in the example of FIG. 2, the flying object 101 is a multicopter (drone), but the present invention is not limited to this. The flight body 101 may be any flight body that can adjust the flight direction of the flight body 101. Examples of the flying object 101 include a small aircraft.

In the flying object 101 of the present embodiment, a plurality of rotors 203 are housed in the housing 201. That is, the plurality of rotors 203 are inner fans. As a result, when the flying object 101 flies over the place 100, the contact between the user or the like of the place 100 and the rotor 203 can be suppressed.

The irradiation unit 202 includes a light source unit 205, a detection unit 206, and a power supply unit (not shown). The light source of the light source unit 205 may be a non-LED (Light Emitting Diode) lamp (for example, a mercury lamp, a metal halide lamp, a fluorescent ultraviolet lamp, an excimer lamp, etc.) or an LED. The light source of the light source unit 205 is, for example, a light emitting substrate using a UV-LED. Ultraviolet rays having a wavelength of at least 380 nm or less are emitted from the light source unit 205. As the ultraviolet rays of the present embodiment, for example, ultraviolet rays having a main wavelength of 222 nm may be used, which has less influence on the human body, and ultraviolet rays having a main wavelength of 222 nm and having a wavelength of 230 nm or more cut off having less influence on the human body. May be used. Further, only ultraviolet rays may be emitted from the light source unit 205, or visible light having a wavelength larger than 380 nm may be emitted from the light source unit 205 together with the ultraviolet rays. Then, by turning on the light source of the light source unit 205, the flying object 101 can illuminate the object (lighting). The light source of the light source unit 205 is preferably light in weight. When an LED is used as the light source of the light source unit 205, the power supply unit (lighting circuit) can be simplified. The detection unit 206 is, for example, a camera or a sensor. Examples of the camera include an AI sensing camera. Examples of the sensor include a motion sensor, a temperature sensor, a position information detection sensor, and the like. In one example, the detection unit 206 detects a location touched by the user at location 100.

The irradiation unit 202 is rotatably connected to the housing 201. The irradiation unit 202 is driven by the drive unit 204, so that the angle formed by the housing 201 and the irradiation unit 202 can be adjusted. The drive unit 204 is, for example, a motor. In the flying object 101, the irradiation direction of the light of the light source unit 205 is adjusted by rotating the irradiation unit 202 by driving the drive unit 204. Further, the irradiation direction of the light from the light source unit 205 can be adjusted according to the attitude of the flying object 101. Further, the drive unit 204 may not be equipped with a motor and may have a configuration in which the irradiation direction is adjusted by being touched (operated) by a person.

The irradiation direction of the light of the light source unit 205 may be changed without rotating the irradiation unit 202. In this case, the light source unit 205 is provided with, for example, a louver capable of changing the irradiation direction of light. Further, the detection unit 206 may be attached to the housing 201 or may be provided separately from the flying object 101. When the detection unit 206 is provided separately from the flying object 101, the detection unit 206 is provided at the place 100. In one example, the detection unit 206 is arranged in a portion above the location 100 in the vertical direction (eg, the ceiling of the location 100).

FIG. 3 shows an example of an air vehicle and a base of the ultraviolet irradiation system according to the embodiment. The aircraft body 101 is connected to the base 302 by the connector 301. Base 302 is, for example, a drone station. Since the base 302 is powered by an external power source (not shown), the flying object 101 can be charged by electrically connecting the connector 301 to the connector 303 of the base 302. Further, the flying object 101 can be stopped at the base 302 by engaging the connector 301 with the base 302. The flying object 101 can turn on the light source of the light source unit 205 of the irradiation unit 202 in a state of being stopped at the base 302. The base 302 is preferably located above the location 100 in the vertical direction.

As shown in one example of FIG. 1, in one example, the base 302 is located on the ceiling of location 100. By stopping the flying object 101 at such a base 302, for example, the flying object 101 becomes the illumination of the place 100. When the light source of the irradiation unit 202 is a UV light, the flying object 101 stays at the base 302, so that the flying object 101 operates as a UV lighting device (UV lighting). As a result, the flying object 101 can illuminate the entire space of the place 100.

In the ultraviolet irradiation system 400 of the present embodiment, the situation at the place 100 is detected by the detection unit 206 of the flying object 101. The detection unit 206 outputs the detection result to the control unit 402. The control unit 402 acquires the detection result of the location 100 from the detection unit 206. In one example, the detection result of the detection unit 206 is contact information indicating which part of the place 100 the user of the place 100 touches. In another example, the detection result of the detection unit 206 is admission information indicating that the user of the place 100 has entered the place 100.

The control unit 402 generates status data indicating the status of the location 100 based on the detection result of the detection unit 206. The situation data is data showing the situation of each of one or more irradiation areas to be irradiated with ultraviolet rays.

Further, the determination data may include information indicating the distance between the flying object 101 and each of the one or more irradiation regions.

When the determination data includes information indicating the distance between the flying object 101 and each of the one or more irradiation areas, the control unit 402 indicates the distance between the irradiation area corresponding to the planned irradiation area and the flying object 101. The irradiation time of ultraviolet rays may be calculated based on the information. In one example, the control unit 402 calculates the required ultraviolet intensity in the planned irradiation region from the ultraviolet illuminance of the light source of the light source unit 205 and the irradiation time of the ultraviolet corresponding to the planned irradiation region. The control unit 402 calculates the effective ultraviolet illuminance of the planned irradiation area based on the distance between the planned irradiation area and the flying object 101 and the ultraviolet intensity of the light source. The control unit 402 calculates the required irradiation time of ultraviolet rays based on the effective ultraviolet illuminance so that the required ultraviolet intensity in the planned irradiation area is maintained. In this case, the control unit 402 controls the flying object 101 so as to keep the distance between the flying object 101 and the planned irradiation area at the above-mentioned distance, and irradiates the planned irradiation area with ultraviolet rays during the required irradiation time of the ultraviolet rays. The irradiation unit 202 is controlled so as to do so.

In one example, the determination unit 403 determines whether or not the irradiation area is to be the planned irradiation area based on the data regarding the position of the irradiation area. In this example, in the place 100, when a certain irradiation area is located near the entrance / exit of the place 100, the determination unit 403 sets the irradiation area as the planned irradiation area. In the place 100, when a certain irradiation area is located at a place far from the entrance / exit of the place 100, the determination unit 403 does not set the irradiation area as the planned irradiation area.

When the situation data includes time history data regarding the irradiation of ultraviolet rays by the flying object 101 for each of one or more irradiation areas, the determination unit 403 determines the time history data regarding the irradiation of ultraviolet rays by the flying object 101 with respect to the irradiation scheduled area.

In one example, the determination unit 403 determines whether or not each of the irradiation regions is to be the scheduled irradiation region based on the time interval between the last irradiation time by the flying object 101 for each of the irradiation regions and the real-time time. to decide. When the above-mentioned time interval in a certain irradiation area is equal to or longer than a predetermined value, the determination unit 403 sets the irradiation area as the irradiation scheduled area. When the above-mentioned time interval in a certain irradiation area is less than a predetermined value, the determination unit 403 does not set the irradiation area as the planned irradiation area.

When the situation data includes a stay history regarding the position and stay time of the resident in each of the one or more irradiation areas, the determination unit 403 generates information indicating the planned irradiation area based on the stay history in the planned irradiation area. You may. In one example, the determination unit 403 determines whether or not each of the irradiation areas is to be an irradiation scheduled area based on the presence or absence of a resident in each of the irradiation areas. When a resident is present in a certain irradiation area, the determination unit 403 sets the irradiation area as the irradiation scheduled area. If there are no residents in a certain irradiation area, the determination unit 403 does not set the irradiation area as the planned irradiation area. In another example, the determination unit 403 determines whether or not each of the irradiation areas is to be an irradiation scheduled area based on the presence time of the resident in each of the irradiation areas. When the presence time of the resident in a certain irradiation area is equal to or longer than a predetermined value, the determination unit 403 sets the irradiation area as the irradiation scheduled area. If the presence time of the resident in a certain irradiation area is less than a predetermined value, the determination unit 403 does not set the irradiation area as the planned irradiation area. In yet another example, the determination unit 403 may adjust the irradiation time of ultraviolet rays in the planned irradiation area based on the staying time of the above-mentioned resident. When the presence time of the resident in a certain irradiation area is equal to or longer than a predetermined value, the determination unit 403 extends the irradiation time of the ultraviolet rays in the irradiation scheduled area. When the presence time of the resident in a certain irradiation area is less than a predetermined value, the determination unit 403 shortens or does not change the irradiation time of the ultraviolet rays in the irradiation scheduled area.

The storage unit 405 stores status data and determination data. The control unit 402 writes the status data to the storage unit 405 and reads the status data from the storage unit 405. The determination unit 403 writes the determination data in the storage unit 405 and reads the determination data from the storage unit 405. The situation data does not have to be stored in the storage unit 405. In this case, after the status data is generated by the control unit 402, the processing by the determination unit 403 using the status data is executed without writing the status data to the storage unit 405. Further, when the storage unit 405 is not provided in the flying object 101, the situation data and the determination data are stored in the storage unit 411 of the management device 401.

The control unit 402 controls the flight of the flying object 101 based on the judgment data. Further, the control unit 402 controls the irradiation unit 202 of the flying object 101 based on the determination data. When irradiating the contaminated portion 103 of the location 100 with ultraviolet rays, the control unit 402 guides the flying object 101 to a certain scheduled irradiation region based on the information indicating the scheduled irradiation region included in the determination data. When the flying object 101 reaches the planned irradiation area, the control unit 402 controls the flight of the flying object 101 and keeps the flying object 101 in the planned irradiation area. The control unit 402 controls the irradiation unit 202 based on the information indicating the irradiation time of the ultraviolet rays corresponding to the planned irradiation area. As a result, the irradiation unit 202 irradiates the planned irradiation area with ultraviolet rays during the above-mentioned irradiation time. When the irradiation of the planned irradiation area with ultraviolet rays is completed, the control unit 402 guides the flying object 101 to another scheduled irradiation area included in the information indicating the planned irradiation area. The control unit 402 irradiates other planned irradiation areas with ultraviolet rays in the same manner as described above. By repeating these processes, the control unit 402 irradiates each of all the scheduled irradiation areas with ultraviolet rays for the corresponding irradiation time. The control unit 402 controls the flying object 101 to stop the flying object 101 at the base 102 after the irradiation of all the planned irradiation areas with ultraviolet rays is completed.

The control unit 402 acquires information indicating the state of the battery 414 from the battery 414. The information indicating the state of the battery 414 includes the remaining capacity value of the battery 414. The control unit 402 compares the remaining capacity value of the battery 414 with a preset predetermined value. When the remaining capacity value of the battery 414 is less than a predetermined value, the control unit 402 controls the flight of the flying object 101 and guides the flying object 101 to the base 302. The control unit 402 controls the flight of the flying object 101 to connect the flying object 101 to the base 302. As a result, the connector 301 of the flying object 101 and the connector 303 of the base 302 are electrically connected. The detection unit 416 of the base 302 detects the electrical connection between the connector 301 of the flying object 101 and the connector 303 of the base 302. The base control unit 408 determines whether or not the connector 301 of the flying object 101 and the connector 303 of the base 302 are electrically connected based on the detection result of the detection unit 416. Based on the determination that the connector 301 and the connector 303 are electrically connected, the base control unit 408 controls the operation of the conversion circuits 413 and 415 in cooperation with the control unit 402 of the flying object 101 and the like. Then, the power supply from the external power source to the flying object 101 is started. As a result, the battery 414 is charged.

The predetermined value of the battery 414 of the flying object 101 may be set via the user interface of the flying object 101. Further, the predetermined value of the battery 414 of the flying object 101 may be set via the user interface 412 of the management device 401.

In one example, the irradiation unit adjusting mechanism 407 includes the drive unit 204 described above, and the control unit 402 changes the direction in which the irradiation unit 202 faces by controlling the drive unit 204. As a result, the irradiation direction of the light of the light source of the light source unit 205 is changed. In another example, the irradiation unit adjusting mechanism 407 includes a louver provided in the light source unit 205, and the control unit 402 changes the irradiation direction of the light of the light source of the light source unit 205 by controlling the louver.

Is feasible. That is, the control unit 402 adjusts the attitude of the flying object 101 and the position of the irradiation unit 202 with respect to each other by controlling the attitude adjustment mechanism 406 and the irradiation unit adjustment mechanism 407, and the irradiation direction of the light from the irradiation unit 202. Can continue to point in a particular direction.

The management device 401 may include a simulation environment unit 410. The simulation environment unit 410 enables the management device 401 to execute an optimized simulation regarding the flight path of the flying object 101 and the irradiation time of ultraviolet rays. The flight path is a path through which the flying object 101 moves between one or more irradiation areas. In the optimization simulation, both the flight path and the irradiation time of the flying object 101 are optimized on the condition that all the states of one or more irradiation regions are set as the target states. AI may be used in this optimization process. Here, the target state is a state in which all of the contaminated points 103 are processed to a value equal to or higher than the target value by irradiating the contaminated place 103 of the place 100 with ultraviolet rays. The target value is, for example, the reduction rate of viruses and the like at the contaminated site 103. In one example, the target state is a state in which the reduction rate of viruses and the like in all of the contaminated sites 103 is 99.9% or more.

The simulation environment unit 410 executes the above-mentioned optimization simulation based on the situation data. As a result, the simulation environment unit 410 calculates the optimum flight path and the optimum irradiation time of the flying object 101 as the simulation result, in which all the states of one or more irradiation regions included in the situation data are set as the target state. .. The control unit 402 acquires the simulation result as determination data via the management unit 409 and the transmission / reception unit 404. The control unit 402 controls the flying object 101 and the irradiation unit 202 based on the flight path and the irradiation time of the simulation result. The simulation environment unit 410 may transmit the simulation result to the transmission / reception unit 404 of the flying object 101 without going through the management unit 409.

The control unit 402 controls the flying object 101 to move the flying object 101 to the planned irradiation area (S603). After the flying object 101 moves to the planned irradiation area, the control unit 402 controls the irradiation unit 202 to start irradiating the planned irradiation area with ultraviolet rays (S604). The control unit 402 determines whether or not the irradiation has been performed for a predetermined time based on the irradiation time data (S605). If the predetermined time has not elapsed (S605-No), the process returns to S605, and the processes after S605 are sequentially executed. When the predetermined time has elapsed (S605-Yes), the control unit 402 controls the irradiation unit 202 to stop the irradiation of ultraviolet rays (S606). The control unit 402 determines whether or not the irradiation of the ultraviolet rays has been completed for all of the planned irradiation areas (S607). When the irradiation of the ultraviolet rays is not completed for all of the planned irradiation areas (S607-No), the control unit 402 acquires the next planned irradiation area (S608). In this case, the process returns to S602, and the processes after S602 are sequentially executed. When the irradiation of the ultraviolet rays is completed for all of the irradiation areas (S607-Yes), the irradiation treatment of the ultraviolet rays is completed.

When the predetermined time has elapsed (S605-Yes), the control unit 402 does not have to stop the irradiation of the ultraviolet rays from the irradiation unit 202. In this case, the control unit 402 proceeds to S607 without processing S606, and the processes after S607 are sequentially executed. That is, the control unit 402 sequentially executes the processes after S607 while the irradiation of the ultraviolet rays from the irradiation unit 202 is continued.
