Description

[Technical Field]

[0001] The present invention relates to an operating facility for a rotary-wing unmanned aerial vehicle. [Background technology]

[0002] A conveying facility is known that has a passage space formed to extend in the vertical direction. Hereinafter, in the description of the background art, the reference numerals in parentheses refer to those in Patent Document 1. Patent Document 1 discloses a cylindrical body (32) for forming a passage space for ascent and descent that is provided across multiple floors, and a lifting body (33) that moves up and down within the cylindrical body using an upper lifting belt (37) and a lower lifting belt (38) to convey articles.

[0003] Meanwhile, there is also known a technology for transporting goods using drones, as described in Patent Document 2. However, when a rotary-wing unmanned aerial vehicle ascends and descends in a passageway space extending in the vertical direction in the above-mentioned transport facility, there is a problem that the flight of the unmanned aerial vehicle may become unstable due to, for example, differences in air pressure caused by the state of the air conditioning equipment on each floor.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-137675 [Patent Document 2] Patent Publication No. 2021-020529 Summary of the Invention [Problem to be solved by the invention]

[0005] Therefore, it is desirable to realize an unmanned aircraft operating facility that has an aisle space that makes it easier to stabilize the flight of rotary-wing unmanned aircraft. [Means for solving the problem]

[0006] The rotary-wing unmanned aerial vehicle according to the present disclosure includes a passage space formed to extend in a vertical direction and through which the unmanned aerial vehicle ascends or descends, and an air pressure control system that controls the air pressure within the passage space, and the air pressure control system controls the air pressure above the unmanned aerial vehicle so that it is lower than the air pressure below the unmanned aerial vehicle. The air pressure control system includes an exhaust unit that is provided above the passage space and exhausts air from the passage space.

[0007] According to this configuration, the air pressure above the unmanned aircraft is lower than the air pressure below the unmanned aircraft, making it easier for the unmanned aircraft to secure lift. This makes it easier to stabilize the flight of the unmanned aircraft. Furthermore, since the energy consumption required for the unmanned aircraft to secure lift can be reduced, it is easier to improve the energy efficiency of the flight of the unmanned aircraft. Furthermore, with this configuration, the air pressure around the unmanned aerial vehicle within the passage space can be appropriately controlled.

[0008] Further features and advantages of the techniques according to the present disclosure will become more apparent from the following description of exemplary and non-limiting embodiments, which proceeds with reference to the drawings. [Brief explanation of the drawings]

[0010] [First embodiment] The operation facility 10 for the unmanned aerial vehicle 11 according to this embodiment will be described below with reference to the drawings. FIG. 1 shows a facility 20 equipped with the operation facility 10 for the unmanned aerial vehicle 11 according to this embodiment. The direction along the vertical direction is defined as the up-down direction Z, and the direction along the horizontal direction is defined as the horizontal direction X. The operation facility 10 is formed to extend in the up-down direction Z, and is equipped with a passage space 30 through which the unmanned aerial vehicle 11 ascends and descends. Here, "extending in the up-down direction Z" means that the extension direction has at least a component in the up-down direction Z. In other words, the passage space 30 may be any space that has a length in the up-down direction Z.

[0011] In this embodiment, the unmanned aerial vehicle 11 is configured to fly through the passage space 30 and transport the article W. The unmanned aerial vehicle 11 is, for example, a rotary-wing aircraft capable of remote control or autonomous flight. Preferably, the unmanned aerial vehicle 11 is an electrically powered rotary-wing aircraft equipped with a storage battery. More preferably, the unmanned aerial vehicle 11 is a wirelessly rechargeable rotary-wing aircraft.

[0012] In this embodiment, the passage space 30 is arranged to penetrate the partition wall 24 that separates the different floors (21u, 21d). In addition, in this embodiment, the passage space 30 is formed by being surrounded by a cylindrical wall 32 extending in the vertical direction Z. The passage space 30 surrounded by the cylindrical wall 32 may have a rectangular, circular, or elliptical cross section. In this embodiment, the cylindrical wall 32 has protruding portions on the upper floor 21u side and the lower floor 21d side. The protruding portions of the cylindrical wall 32 on the upper floor 21u side also serve as fences to prevent workers and the like from falling. It is desirable that the cylindrical wall 32 on the lower floor 21d side does not have any protruding portions.

[0013] In this embodiment, the operation facility 10 is provided with opening / closing doors 34u and 34d that divide the aisle space 30 in the vertical direction Z. These opening / closing doors 34u and 34d are opened when the unmanned aerial vehicle 11 passes through and are closed after the unmanned aerial vehicle 11 has passed. In the illustrated example, an upper opening / closing door 34u is provided at the top of the aisle space 30. A lower opening / closing door 34d is provided at the bottom of the aisle space 30. The lower opening / closing door 34d also functions as a device to prevent the unmanned aerial vehicle 11 from falling to the lower floor 21d. In this embodiment, the upper opening / closing door 34u and the lower opening / closing door 34d are double-swing sliding doors that open and close in the horizontal direction X, but they may also be single-swing sliding doors or sliding doors that open and close in the vertical direction Z. They may also be double-swing doors.

[0014] In this embodiment, the passage space 30 is arranged so as to penetrate a partition wall 24 that separates multiple floors (21u, 21d) that are air-pressure controlled to have different air pressures from one another. In the illustrated example, the upper floor 21u is located on the second floor (2F), and the lower floor 21d is located on the first floor (1F). The following describes, as an example, a case in which the passage space 30 of the operation equipment 10 for the unmanned aerial vehicle 11 according to this embodiment is arranged so as to penetrate a partition wall 24 that separates the upper floor 21u and the lower floor 21d, which are two clean rooms where items W are processed in a clean environment. Examples of facilities 20 that have two clean rooms, the upper floor 21u and the lower floor 21d, include factories that produce electronic components such as semiconductors, pharmaceuticals, and food, as well as warehouses and ships.

[0015] In this embodiment, the upper layer 21u includes an upper layer placement section 26 on which an item W is placed. The lower layer 21d includes a lower layer placement section 27 on which an item W is placed. The unmanned aerial vehicle 11, for example, transports the item W from the upper layer placement section 26 to the lower layer placement section 27, or transports the item W from the lower layer placement section 27 to the upper layer placement section 26. In the illustrated example, the upper layer placement section 26 is a storage unit and the lower layer placement section 27 is a conveying device, but the upper layer placement section 26 may be a conveying device and the lower layer placement section 27 may be a storage unit. Furthermore, both the upper layer placement section 26 and the lower layer placement section 27 may be a storage unit, a conveying device, a processing device, a placement table, etc. Examples of storage units include storage shelves for temporarily storing items W, refrigerators, freezers, and automated warehouses equipped with stacker cranes. Examples of the transport device include conveyors such as belt conveyors and roller conveyors, automatic guided vehicles, freight vehicles, etc. Examples of the processing device include processing devices for electronic parts such as semiconductors, chemicals, and food products.

[0016] In this embodiment, the air pressure is controlled so that the air pressure in the upper layer 21u is higher than the air pressure in the lower layer 21d. That is, the clean room in the upper layer 21u is made cleaner than the clean room in the lower layer 21d. The air pressure in the upper layer 21u and the air pressure in the lower layer 21d are controlled, for example, by an air conditioning system (not shown). In this manner, the clean room in the upper layer 21u, which has a higher level of cleanliness, can be less susceptible to the effects of downwash blown downward by the rotary-wing unmanned aerial vehicle 11 as it flies. Preferably, the air pressure in the passage space 30 is controlled by the air pressure control system 40 (described later) so that it is lower than the air pressure in the upper layer 21u. More preferably, the air pressure in the passage space 30 is controlled by the air pressure control system 40 (described later) so that it is lower than the air pressure in the lower layer 21d.

[0017] 2 shows a block diagram of the operation equipment 10. The operation equipment 10 is equipped with an air pressure control system 40 that controls the air pressure in the passage space 30. In this embodiment, the air pressure control system 40 is equipped with an air pressure detection unit that detects the air pressure at multiple locations in the vertical direction Z in the passage space 30. In this embodiment, an upper air pressure sensor 41u provided above the exhaust unit 42 and a lower air pressure sensor 41d provided below the air supply unit 52 function as the air pressure detection unit. Various pressure gauges and differential pressure gauges are used as the air pressure detection unit.

[0018] In this embodiment, the air pressure control system 40 includes an exhaust unit 42 that is provided above the passage space 30 and exhausts air from the passage space 30. The exhaust unit 42 is provided to penetrate the cylindrical wall 32. The exhaust unit 42 is a fan filter unit that includes a fan 43 and a filter 44. Preferably, the exhaust unit 42 includes one or more pairs of exhaust holes 45 that face each other in the cylindrical wall 32. In the illustrated example, the exhaust unit 42 includes a duct 46. Preferably, the exhaust unit 42 is configured to exhaust gas exhausted from the passage space 30 to the outside of the clean room via the duct 46, but may also be configured to exhaust gas exhausted from the passage space 30 to the upper layer 21u.

[0019] In this embodiment, the air pressure control system 40 includes an air supply unit 52 that is provided below the passage space 30 and supplies air to the passage space 30. The air supply unit 52 is provided to penetrate the cylindrical wall 32. The air supply unit 52 is a fan filter unit that includes a fan 53 and a filter 54. Preferably, the air supply unit 52 includes one or more pairs of air supply holes 55 that face each other in the cylindrical wall 32. In the illustrated example, the air supply unit 52 includes a duct 56. Preferably, the air supply unit 52 is configured to draw in gas of a cleanliness equivalent to that of a clean room on the upper layer 21u via the duct 56 and supply it to the passage space 30, but it may also be configured to draw in gas from the lower layer 21d.

[0020] In this embodiment, the air pressure control system 40 includes a position information acquisition unit 60 that acquires position information indicating the position of the unmanned aerial vehicle 11. The position information acquisition unit 60 acquires, for example, height information or coordinate information of the unmanned aerial vehicle 11 as position information indicating the position of the unmanned aerial vehicle 11. In the illustrated example, an upper door sensor 61, an exhaust-side upper sensor 62, an exhaust-side lower sensor 63, an intake-side upper sensor 67, an intake-side lower sensor 68, and a lower door sensor 69 function as the position information acquisition unit 60. These sensors may be, for example, optical sensors such as infrared sensors, ultrasonic sensors, or the like.

[0021] In this embodiment, the air pressure control system 40 includes an air pressure control device 70 that includes a processor such as a central processing unit (CPU) and a main storage device accessible by the processor, such as a random access memory (RAM) or a read-only memory (ROM). Each function of the air pressure control device 70 is realized by the cooperation of hardware included in the air pressure control device 70 and a program executed on the hardware, such as the processor. Specifically, the air pressure control device 70 executes a program stored in a storage device (such as a main storage device or a separately provided storage unit) to realize each function of the air pressure control device 70. In other words, a program (e.g., an air pressure control program) for causing a computer to realize each function of the air pressure control device 70 is stored in a storage device accessible by the computer. This program is provided, for example, by a storage medium or via a communication network. The provided program is then stored in a storage device accessible by the computer. In this embodiment, the air pressure control device 70 (specifically, the processor included in the air pressure control system 40) functions as a "computer."

[0022] In this embodiment, the air pressure control device 70 includes an upper door control unit 72 that controls the opening and closing of the upper opening door 34u and a lower door control unit 78 that controls the opening and closing of the lower opening door 34d. Preferably, the upper door control unit 72 controls the upper opening door 34u, and the lower door control unit 78 controls the lower opening door 34d, so as to prevent multiple unmanned aerial vehicles 11 from being located in the passage space 30. For example, if the air pressure control device 70 determines that an unmanned aerial vehicle 11 is located in the passage space 30 based on position information acquired by the position information acquisition unit 60, the upper door control unit 72 continues to close the upper opening door 34u even if the upper door sensor 61 detects the approach of the unmanned aerial vehicle 11. Furthermore, for example, if the air pressure control device 70 determines that an unmanned aerial vehicle 11 is located in the passage space 30 based on position information acquired by the position information acquisition unit 60, the lower door control unit 78 continues to close the lower opening door 34d even if the lower door sensor 69 detects the approach of the unmanned aerial vehicle 11.

[0023] In this embodiment, the air pressure control system 40 controls the air pressure above the unmanned aerial vehicle 11 so that it is lower than the air pressure below the unmanned aerial vehicle 11. In this way, the unmanned aerial vehicle 11 can easily secure lift. Also, in this embodiment, the air pressure control device 70 of the air pressure control system 40 controls the air pressure in the passage space 30 based on the position information acquired by the position information acquisition unit 60.

[0024] In this embodiment, the air pressure control device 70 includes an exhaust control unit 73 that controls the exhaust pressure Po of the exhaust unit 42 and an intake control unit 77 that controls the intake pressure Pi of the intake unit 52. Preferably, the exhaust control unit 73 controls the exhaust unit 42, and the intake control unit 77 controls the intake unit 52, so that the exhaust pressure Po of the exhaust unit 42 is equal to or greater than the intake pressure Pi of the intake unit 52. This configuration generates an updraft in the passage space 30, making it easier for the unmanned aerial vehicle 11 to secure lift. Furthermore, it is easy to suppress the exhaust of gas from the passage space 30 to the upper layer 21u through the upper opening of the passage space 30 when the upper opening-close door 34u opens the upper opening of the passage space 30, and the exhaust of gas from the passage space 30 to the lower layer 21d through the opening of the lower opening of the passage space 30 when the lower opening-close door 34d opens the lower opening of the passage space 30.

[0025] In this embodiment, when the air pressure control device 70 determines that the unmanned aerial vehicle 11 will pass through the first region E1, the exhaust control unit 73 reduces the exhaust pressure Po of the exhaust unit 42 to a value lower than that before the air pressure control device 70 made the determination. Here, the first region E1 is the region near the exhaust unit 42 in the passage space 30. Preferably, the air pressure control device 70 determines that the unmanned aerial vehicle 11 will pass through the first region E1 based on position information acquired by the position information acquisition unit 60.

[0026] In this embodiment, when the air pressure control device 70 determines that the unmanned aerial vehicle 11 will pass through the second area E2, the air supply control unit 77 lowers the supply air pressure Pi of the air supply unit 52 compared to before the air pressure control device 70 made the determination. Here, the second area E2 is the area near the air supply unit 52 in the passage space 30. Preferably, the air pressure control device 70 determines that the unmanned aerial vehicle 11 will pass through the second area E2 based on position information acquired by the position information acquisition unit 60.

[0027] In this embodiment, the position information acquisition unit 60 includes a first detection unit that detects the approach of the unmanned aerial vehicle 11 to a first area E1, which is an area near the exhaust unit 42 in the passage space 30, and when the first detection unit detects the unmanned aerial vehicle 11, the air pressure control device 70 determines that the unmanned aerial vehicle 11 is passing through the first area E1, and the exhaust control unit 73 lowers the exhaust pressure Po of the exhaust unit 42 compared to before the first detection unit detected the unmanned aerial vehicle 11. In this embodiment, the upper door sensor 61 and the exhaust-side lower sensor 63 function as the first detection unit.

[0028] In this embodiment, the position information acquisition unit 60 is equipped with a second detection unit that detects the approach of the unmanned aerial vehicle 11 to the second area E2, which is the area near the air supply unit 52 in the passage space 30, and when the second detection unit detects the unmanned aerial vehicle 11, the air pressure control device 70 determines that the unmanned aerial vehicle 11 is passing through the second area E2, and the air supply control unit 77 lowers the air supply pressure Pi of the air supply unit 52 compared to before the second detection unit detected the unmanned aerial vehicle 11. In this embodiment, the lower door sensor 69 and the air supply side upper sensor 67 function as the second detection unit.

[0029] In this embodiment, when the unmanned aerial vehicle 11 passes through a first region E1, which is a region in the vertical direction Z in the passage space 30 where the exhaust unit 42 is disposed, the air pressure control system 40 lowers the exhaust pressure Po of the exhaust unit 42 compared to before the unmanned aerial vehicle 11 entered the first region E1. Furthermore, in this embodiment, the air pressure control system 40 includes a first detection unit (upper door sensor 61, exhaust-side lower sensor 63) that detects the unmanned aerial vehicle 11 approaching the first region E1, and determines that the unmanned aerial vehicle 11 is passing through the first region E1 when the first detection unit detects the unmanned aerial vehicle 11. This makes it easier to stabilize the flight state of the unmanned aerial vehicle 11 when it passes through the first region E1. Furthermore, it is possible to appropriately determine when the unmanned aerial vehicle 11 is passing through the first region E1. In the illustrated example, the first region E1 includes a region in the vertical direction Z where the exhaust hole 45 of the exhaust unit 42 is disposed.

[0030] In this embodiment, when the unmanned aerial vehicle 11 passes through the second area E2, which is the area in the vertical direction Z in the passage space 30 where the air supply unit 52 is located, the air pressure control system 40 lowers the supply air pressure Pi of the air supply unit 52 compared to before the unmanned aerial vehicle 11 entered the second area E2. Furthermore, in this embodiment, the air pressure control system 40 includes a second detection unit (lower door sensor 69, upper air supply side sensor 67) that detects the unmanned aerial vehicle 11 approaching the second area E2, and determines that the unmanned aerial vehicle 11 is passing through the second area E2 when the second detection unit detects the unmanned aerial vehicle 11. This makes it easier to stabilize the flight state of the unmanned aerial vehicle 11 when it passes through the second area E2. Furthermore, it is possible to appropriately determine when the unmanned aerial vehicle 11 is passing through the second area E2. In the illustrated example, the second area E2 includes the area in the vertical direction Z where the air supply hole 55 of the air supply unit 52 is located.

[0031] In this embodiment, the air pressure control system 40 controls the air pressure in the passage space 30 based on the position information acquired by the position information acquisition unit 60 and the detection results of the air pressure detection units (41u, 41d). In this way, it is possible to appropriately control the air pressure above the unmanned aerial vehicle 11 so that it is lower than the air pressure below the unmanned aerial vehicle 11, depending on the position of the unmanned aerial vehicle 11.

[0032] An example of air pressure control within the passage space 30 by the air pressure control system 40 when the unmanned aerial vehicle 11 descends will be described below with reference to Figures 3 to 7. Figure 3 shows a state in which the upper and lower opening / closing doors 34u and 34d are closed, and the unmanned aerial vehicle 11 is located outside the upper opening / closing door 34u. In this state, the exhaust pressure Po of the exhaust unit 42 is set to a first exhaust pressure Po1, and the supply pressure Pi of the supply unit 52 is set to a first supply pressure Pi1.

[0033] When the position information acquisition unit 60 detects the approach of the unmanned aerial vehicle 11 to the first area E1 outside the passage space 30, i.e., when the upper door sensor 61 detects the unmanned aerial vehicle 11, the exhaust control unit 73 of the air pressure control device 70 sets the exhaust pressure Po of the exhaust unit 42 to a second exhaust pressure Po2 lower than the first exhaust pressure Po1. The air supply control unit 77 of the air pressure control device 70 also sets the air supply pressure Pi of the air supply unit 52 to a second air supply pressure Pi2 lower than the first air supply pressure Pi1. Next, the upper door control unit 72 of the air pressure control device 70 opens the upper opening door 34u. FIG. 4 shows the state after the upper opening door 34u has been opened. This reduces the downward force acting on the unmanned aerial vehicle 11 located above the upper opening door 34u due to the air pressure difference caused when the upper opening door 34u is opened and the downward force acting on the unmanned aerial vehicle 11 due to the exhaust of the exhaust unit 42. Furthermore, even if the unmanned aerial vehicle 11 loses lift, an upward force is generated on the unmanned aerial vehicle 11 due to the exhaust from the exhaust unit 42 and the air intake from the air intake unit 52, making it easy for the unmanned aerial vehicle 11 to recover lift between the exhaust unit 42 and the air intake unit 52.

[0034] When unmanned aerial vehicle 11 descends from the state shown in Figure 4 and is detected by exhaust-side lower sensor 63, upper door control unit 72 closes upper opening / closing door 34u. Next, exhaust control unit 73 sets exhaust pressure Po of exhaust unit 42 to third exhaust pressure Po3, which is higher than second exhaust pressure Po2. Also, air supply control unit 77 sets supply pressure Pi of air supply unit 52 to third supply pressure Pi3, which is higher than second supply pressure Pi2.

[0035] Figure 5 shows a state in which the unmanned aerial vehicle 11 has descended further and is now located below the exhaust-side lower sensor 63 and above the intake-side upper sensor 67. In the state shown in Figure 5, the exhaust-side lower sensor 63 and the intake-side upper sensor 67 do not detect the unmanned aerial vehicle 11.

[0036] When unmanned aerial vehicle 11 descends from the state shown in Figure 5 and is detected by intake-side upper sensor 67, exhaust control unit 73 sets exhaust pressure Po of exhaust unit 42 to fourth exhaust pressure Po4, which is lower than third exhaust pressure Po3. Also, intake control unit 77 sets intake pressure Pi of intake unit 52 to fourth intake pressure Pi4, which is lower than third intake pressure Pi3. Preferably, fourth intake pressure Pi4 is zero.

[0037] As the unmanned aerial vehicle 11 descends further and is detected by the air intake lower sensor 68, the lower door control unit 78 opens the lower opening / closing door 34d. FIG. 6 shows the state after the lower opening / closing door 34d has been opened. This reduces the downward force generated by the air intake unit 52 supplying air to the unmanned aerial vehicle 11 when the unmanned aerial vehicle 11 is located below the air intake unit 52. Furthermore, gas in the passage space 30 is more likely to flow toward the exhaust unit 42, preventing it from exiting the lower opening / closing door 34d. After the lower opening / closing door 34d is opened, the fourth exhaust pressure Po4 may be set to the same value as the third exhaust pressure Po3 or higher than the third exhaust pressure Po3.

[0038] When unmanned aerial vehicle 11 descends from the state shown in Figure 6 and is detected by lower door sensor 69, lower door control unit 78 closes lower opening / closing door 34d. Next, exhaust control unit 73 sets exhaust pressure Po of exhaust unit 42 to fifth exhaust pressure Po5, which is higher than fourth exhaust pressure Po4. Also, air supply control unit 77 sets supply pressure Pi of air supply unit 52 to fifth supply pressure Pi5, which is higher than fourth supply pressure Pi4. Figure 7 shows a state in which upper opening / closing door 34u and lower opening / closing door 34d are closed and unmanned aerial vehicle 11 is located outside lower opening / closing door 34d.

[0039] Next, an example of air pressure control within the passage space 30 by the air pressure control system 40 when the unmanned aerial vehicle 11 ascends will be described with reference to the drawings in the order of Figure 7 to Figure 3. Figure 7 shows a state in which the ascending unmanned aerial vehicle 11 is positioned outside the lower opening / closing door 34d.

[0040] When the position information acquisition unit 60 detects the approach of the unmanned aerial vehicle 11 to the second area E2 outside the passage space 30, i.e., when the lower door sensor 69 detects the unmanned aerial vehicle 11, the exhaust control unit 73 of the air pressure control device 70 sets the exhaust pressure Po of the exhaust unit 42 to a fourth exhaust pressure Po4, which is lower than the fifth exhaust pressure Po5. The air supply control unit 77 of the air pressure control device 70 also sets the air supply pressure Pi of the air supply unit 52 to a fourth air supply pressure Pi4, which is lower than the fifth air supply pressure Pi5. Preferably, the fourth air supply pressure Pi4 is 0. Next, the lower door control unit 78 of the air pressure control device 70 opens the lower opening / closing door 34d. Figure 6 shows the state after the lower opening / closing door 34d has been opened. This reduces the downward force generated by the air supply unit 52 supplying air to the unmanned aerial vehicle 11 located below the air supply unit 52. Furthermore, gas in the passage space 30 is more likely to flow toward the exhaust unit 42, preventing it from exiting the lower opening / closing door 34d.

[0041] When unmanned aerial vehicle 11 ascends from the state shown in Figure 6 and is detected by intake-side upper sensor 67, lower door control unit 78 closes lower opening / closing door 34d. Next, exhaust control unit 73 sets exhaust pressure Po of exhaust unit 42 to third exhaust pressure Po3, which is higher than fourth exhaust pressure Po4. Also, intake control unit 77 sets intake pressure Pi of intake unit 52 to third intake pressure Pi3, which is higher than fourth intake pressure Pi4.

[0042] Figure 5 shows a state in which the unmanned aerial vehicle 11 has risen further and is now located above the intake side upper sensor 67 and below the exhaust side lower sensor 63. In the state shown in Figure 5, the intake side upper sensor 67 and the exhaust side lower sensor 63 do not detect the unmanned aerial vehicle 11.

[0043] 5 and is detected by the exhaust-side lower sensor 63, the exhaust control unit 73 sets the exhaust pressure Po of the exhaust unit 42 to a second exhaust pressure Po2 that is lower than the third exhaust pressure Po3. Also, the supply air control unit 77 sets the supply pressure Pi of the supply air unit 52 to a second supply pressure Pi2 that is lower than the third supply pressure Pi3.

[0044] As the unmanned aerial vehicle 11 rises further and is detected by the exhaust-side upper sensor 62, the upper door control unit 72 opens the upper opening / closing door 34u. Figure 4 shows the state after the upper opening / closing door 34u has been opened. In this way, when the unmanned aerial vehicle 11 is located above the exhaust unit 42, the downward force generated by the exhaust of the exhaust unit 42 on the unmanned aerial vehicle 11 can be reduced.

[0045] When unmanned aerial vehicle 11 ascends from the state shown in Figure 4 and is detected by upper door sensor 61, upper door control unit 72 closes upper opening / closing door 34u. Next, exhaust control unit 73 sets exhaust pressure Po of exhaust unit 42 to first exhaust pressure Po1, which is higher than second exhaust pressure Po2. Also, air supply control unit 77 sets supply pressure Pi of air supply unit 52 to first supply pressure Pi1, which is higher than second supply pressure Pi2. Figure 3 shows a state in which upper opening / closing door 34u and lower opening / closing door 34d are closed, and unmanned aerial vehicle 11 is located outside upper opening / closing door 34u.

[0046] In this embodiment, the first exhaust pressure Po1, the third exhaust pressure Po3, and the fifth exhaust pressure Po5 are the same value, but they may be different from each other. Also, in this embodiment, the second exhaust pressure Po2 and the fourth exhaust pressure Po4 are the same value, but they may be different from each other. Also, in this embodiment, the first supply pressure Pi1, the third supply pressure Pi3, and the fifth supply pressure Pi5 are the same value, but they may be different from each other.

[0047] In this embodiment, the fourth exhaust pressure Po4 may be set to the same value as the third exhaust pressure Po3 or the same value as the fifth supply pressure Pi5. In this embodiment, the fourth exhaust pressure Po4 may be set to a value higher than the third exhaust pressure Po3 or the fifth supply pressure Pi5. In this way, lift can be more easily secured when the unmanned aerial vehicle 11 is located near the air supply unit 52.

[0048] Preferably, the first exhaust pressure Po1, the second exhaust pressure Po2, the third exhaust pressure Po3, the fourth exhaust pressure Po4, and the fifth exhaust pressure Po5 are greater than the first supply pressure Pi1, the second supply pressure Pi2, the third supply pressure Pi3, the fourth supply pressure Pi4, and the fifth supply pressure Pi5, respectively. This makes it easier to control the air pressure above unmanned aerial vehicle 11 so that it is lower than the air pressure below unmanned aerial vehicle 11.

[0049] Preferably, the second exhaust pressure Po2, the third exhaust pressure Po3, and the fourth exhaust pressure Po4 when the unmanned aerial vehicle 11 is ascending are higher than the second exhaust pressure Po2, the third exhaust pressure Po3, and the fourth exhaust pressure Po4 when the unmanned aerial vehicle 11 is descending. In this way, the energy consumption of the unmanned aerial vehicle 11 can be further reduced when the unmanned aerial vehicle 11 is ascending.

[0050] Preferably, the air pressure control device 70 of the air pressure control system 40 determines the exhaust pressure Po (e.g., the first exhaust pressure Po1, the second exhaust pressure Po2, the third exhaust pressure Po3, the fourth exhaust pressure Po4, and the fifth exhaust pressure Po5) and the supply pressure Pi (e.g., the first supply pressure Pi1, the second supply pressure Pi2, the third supply pressure Pi3, the fourth supply pressure Pi4, and the fifth supply pressure Pi5) based on the position information acquired by the position information acquisition unit 60 and the detection results of the air pressure detection units (41u, 41d) so that the air pressure above the unmanned aerial vehicle 11 (e.g., the air pressure detected by the upper air pressure sensor 41u) is lower than the air pressure below the unmanned aerial vehicle 11 (e.g., the air pressure detected by the lower air pressure sensor 41d).

[0051] In this embodiment, the passage space 30 is formed in a columnar shape along the vertical direction Z. When the unmanned aerial vehicle 11 descends through this passage space 30, it is desirable to have it descend in a spiral trajectory. In this way, it is easy to avoid the occurrence of a vortex ring state when the unmanned aerial vehicle 11 descends.

[0052] Second Embodiment The following describes the operation equipment 10 for an unmanned aerial vehicle 11 according to the second embodiment with reference to the drawings. FIG. 8 is a diagram illustrating the operation equipment 10 according to the second embodiment. This embodiment differs from the first embodiment in that the upper and lower levels 21u and 21d are not clean rooms, and the operation equipment 10 does not include the upper opening / closing door 34u, the upper door sensor 61, the upper door control unit 72, the lower opening / closing door 34d, the lower door sensor 69, the lower door control unit 78, the filter 44 of the exhaust unit 42, and the filter 54 of the air supply unit 52. The following mainly focuses on the differences from the first embodiment. Note that the points not specifically described are the same as those in the first embodiment. Note that the air pressure control device 70 is omitted from FIG. 8.

[0053] In this embodiment, the exhaust-side upper sensor 62 is configured to detect an unmanned aerial vehicle 11 located at the upper limit of the first area E1. Furthermore, the exhaust-side lower sensor 63 is configured to detect an unmanned aerial vehicle 11 located at the lower limit of the first area E1. The exhaust-side upper sensor 62 and the exhaust-side lower sensor 63 function as a first detection unit that detects the approach of the unmanned aerial vehicle 11 to the first area E1, and when the unmanned aerial vehicle 11 is detected by this first detection unit, it is determined that the unmanned aerial vehicle 11 is passing through the first area E1.

[0054] In this embodiment, the intake side upper sensor 67 is configured to detect an unmanned aerial vehicle 11 located at the upper limit of the second area E2. The intake side lower sensor 68 is configured to detect an unmanned aerial vehicle 11 located at the lower limit of the second area E2. The intake side upper sensor 67 and the intake side lower sensor 68 function as a second detection unit that detects the unmanned aerial vehicle 11 approaching the second area E2, and when the second detection unit detects the unmanned aerial vehicle 11, it is determined that the unmanned aerial vehicle 11 is passing through the second area E2.

[0055] Third Embodiment The following describes the operation equipment 10 for an unmanned aerial vehicle 11 according to the third embodiment with reference to the drawings. FIG. 9 is a diagram showing the operation equipment 10 of this embodiment. The following description will focus on the differences from the first embodiment. Note that points that are not specifically described are the same as those of the first embodiment. Note that the air pressure control device 70 is omitted from FIG. 9.

[0056] In this embodiment, the passage space 30 is formed in a columnar shape that slopes downward toward one side in the horizontal direction X. In this embodiment, the upper opening / closing door 34u and the lower opening / closing door 34d are single-leaf doors. The upper opening / closing door 34u is a sliding door that is opened by being pulled to one side in the horizontal direction X. The lower opening / closing door 34d is a sliding door that is opened by being pulled to the other side in the horizontal direction X.

[0057] [Fourth embodiment] The following describes an operation facility 10 for an unmanned aerial vehicle 11 according to the fourth embodiment with reference to the drawings. FIG. 10 is a diagram showing the operation facility 10 of this embodiment. The following description will focus on differences from the first embodiment. Note that points that are not specifically described are the same as those of the first embodiment. Note that the air pressure control device 70 is omitted from FIG. 10.

[0058] In this embodiment, the passage space 30 is arranged to penetrate the partition wall 24 that separates the three floors, the upper floor 21u, the middle floor 21m, and the lower floor 21d, and the passage space 30 is formed by being surrounded by a cylindrical wall 32 that extends at least in the vertical direction Z. In the illustrated example, the upper floor 21u is arranged on the second floor above ground, the middle floor 21m is arranged on the first floor above ground, and the lower floor 21d is arranged on the first basement floor.

[0059] In this embodiment, the exhaust unit 42 is provided with exhaust holes 45 in the ceiling of the passage space 30, which exhaust air upward from the passage space 30. The air supply unit 52 is provided with air supply holes 55 in the bottom of the passage space 30, which supply air upward into the passage space 30. In this embodiment, a first region E1, which is a region near the exhaust unit 42 in the passage space 30, has an upper limit equal to the ceiling of the passage space 30 and a lower limit equal to the exhaust-side lower sensor 63. In addition, a second region E2, which is a region near the air supply unit 52 in the passage space 30, has an upper limit equal to the intake-side upper sensor 67 and a lower limit equal to the bottom of the passage space 30. In this embodiment, the exhaust-side upper sensor 62 and the intake-side lower sensor 68 are not provided.

[0060] In this embodiment, the operation facility 10 is provided with a middle opening / closing door 34m that allows the unmanned aerial vehicle 11 to travel between the passage space 30 and the middle floor 21m. Although not shown, the air pressure control device 70 also has a middle door control unit that controls the opening and closing of the middle opening / closing door 34m. In this embodiment, when the air pressure control device 70 determines, based on position information acquired by the position information acquisition unit 60, that the unmanned aerial vehicle 11 will pass through the middle opening / closing door 34m, the middle door control unit of the air pressure control device 70 opens and closes the middle opening / closing door 34m. In the example shown, the position information acquisition unit 60 has a middle door sensor 65 that functions as a third detection unit that detects the unmanned aerial vehicle 11 approaching the middle opening / closing door 34m.

[0061] Preferably, when the air pressure control device 70 determines that the unmanned aerial vehicle 11 will pass through the middle opening door 34m, the exhaust control unit 73 lowers the exhaust pressure Po of the exhaust unit 42 compared to before the determination. Also, when the air pressure control device 70 determines that the unmanned aerial vehicle 11 will pass through the middle opening door 34m, the air supply control unit 77 lowers the air supply pressure Pi of the air supply unit 52 compared to before the determination. In this way, it is easier to stabilize the flight state of the unmanned aerial vehicle 11 even when the unmanned aerial vehicle 11 passes through the middle opening door 34m. Even more preferably, the air pressure control device 70 determines that the unmanned aerial vehicle 11 will pass through the middle opening door 34m based on position information acquired by the position information acquisition unit 60.

[0062] Fifth Embodiment The following describes an operation facility 10 for an unmanned aerial vehicle 11 according to the fifth embodiment with reference to the drawings. FIG. 11 is a diagram showing the operation facility 10 of this embodiment. The following description will focus on differences from the first embodiment. Note that points that are not specifically described are the same as those of the first embodiment. Note that the air pressure control device 70 is omitted from FIG. 11.

[0063] In this embodiment, the operation facility 10 further includes a transport port 81 that allows the unmanned aerial vehicle 11 to take off and land and to receive and deliver goods W. This transport port 81 is located in a position that connects to the passage space 30. This allows the unmanned aerial vehicle 11 to land at the transport port 81, where maintenance or charging of the unmanned aerial vehicle 11 can be performed, for example. In this embodiment, the transport port 81 includes multiple wireless charging devices 82. These charging devices 82 are configured to be able to charge the unmanned aerial vehicle 11 both when it is holding goods W and when it is not holding goods W. The transport port 81 also includes a storage shelf 83 for storing the unmanned aerial vehicle 11.

[0064] In this embodiment, the operation facility 10 includes a transport device 84 capable of transporting the unmanned aerial vehicle 11 and the item W between the transport port 81 and the aisle space 30 and between the transport port 81 and the outside of the aisle space 30, and a removal door 85 that separates the inside and outside of the aisle space 30. The transport port 81 also includes a stacker crane (not shown) that places the landed unmanned aerial vehicle 11 on a storage shelf 83. The transport port 81 may be capable of only one of the takeoff and landing of the unmanned aerial vehicle 11 and the transfer of the item W. If the transport port 81 is capable of transferring the item W, it is desirable to provide the transport ports 81 at multiple locations in the vertical direction Z along the aisle space 30. This allows the item W to be transported in the vertical direction Z by the unmanned aerial vehicle 11, which flies stably. Therefore, the item W can be efficiently transported across multiple floors of a building, for example.

[0065] Other Embodiments Next, other embodiments of the operation equipment 10 for the unmanned aerial vehicle 11 will be described.

[0066] (1) In the first, second, fourth, and fifth embodiments, the passage space 30 through which the unmanned aerial vehicle 11 ascends and descends is formed to extend along the vertical direction Z. However, the present invention is not limited to such an example. For example, as in the third embodiment, the extension direction of the passage space 30 may be inclined with respect to the vertical direction Z. Furthermore, the shape of the passage space 30 does not have to be a straight cylinder. For example, the shape may be such that the cross-sectional area varies depending on the position in the vertical direction Z, or the shape may be curved or bent when viewed from the side. Furthermore, the passage space 30 may be a passage dedicated to the ascent or descent of the unmanned aerial vehicle 11. Furthermore, in the first to fourth embodiments, the operation facility 10 may be provided with a transport port 81, as in the fifth embodiment.

[0067] (2) In the above embodiment, an example has been described in which the passage space 30 is provided in a multi-story facility 20 and is arranged to penetrate a partition wall 24 that separates two clean rooms, the upper level 21u and the lower level 21d. However, the present invention is not limited to such an example, and the passage space 30 may be, for example, a passage formed to extend in the vertical direction Z in a one-story building. Furthermore, the upper level 21u and the lower level 21d do not necessarily have to be clean rooms, and the levels do not necessarily have to be separated by a partition wall 24. Furthermore, the passage space 30 does not necessarily have to be surrounded by a cylindrical wall 32.

[0068] (3) In the above embodiment, the air pressure control system 40 has been described as having an example of a configuration including an exhaust unit 42 and an air supply unit 52. However, the present invention is not limited to such an example, and the air pressure control system 40 may have only one of the exhaust unit 42 and the air supply unit 52. Furthermore, the air pressure control system 40 may not have the exhaust unit 42 and the air supply unit 52, and may control the air pressure in the passage space 30 using another method. Furthermore, the air may be exhausted only from the top of the passage space 30, or may be supplied only to the bottom of the passage space 30.

[0069] (4) In the above embodiment, the air pressure control system 40 has been described as including a configuration including a position information acquisition unit 60 that acquires position information indicating the position of the unmanned aerial vehicle 11. However, without being limited to such an example, the air pressure control system 40 may be configured to control the air pressure in the passage space 30 without acquiring position information indicating the position of the unmanned aerial vehicle 11. Furthermore, the position information acquisition unit 60 may be configured to acquire coordinate information as position information indicating the position of the unmanned aerial vehicle 11, for example, by using a global positioning system (GPS), realtime kinematic (RTK), or processing an image captured by an imaging device.

[0070] (5) In the above embodiment, an example has been described in which the upper door control unit 72 closes the upper opening / closing door 34u when the unmanned aerial vehicle 11 is detected by the exhaust-side lower sensor 63 while the unmanned aerial vehicle 11 is descending. However, without being limited to such an example, for example, the upper door control unit 72 may close the upper opening / closing door 34u when the unmanned aerial vehicle 11 is no longer detected by the exhaust-side upper sensor 62 while the unmanned aerial vehicle 11 is descending. Furthermore, the upper door control unit 72 may open or close the upper opening / closing door 34u based on coordinate information of the unmanned aerial vehicle 11 acquired by the position information acquisition unit 60.

[0071] (6) In the above embodiment, an example has been described in which the lower door control unit 78 closes the lower opening / closing door 34d when the unmanned aerial vehicle 11 is detected by the intake-side upper sensor 67 during ascent of the unmanned aerial vehicle 11. However, without being limited to such an example, for example, the lower door control unit 78 may close the lower opening / closing door 34d when the unmanned aerial vehicle 11 is no longer detected by the intake-side lower sensor 68 during ascent of the unmanned aerial vehicle 11. Alternatively, the lower door control unit 78 may open or close the lower opening / closing door 34d based on coordinate information of the unmanned aerial vehicle 11 acquired by the position information acquisition unit 60.

[0072] (7) The configurations disclosed in the above-described embodiments may be combined with configurations disclosed in other embodiments as long as no contradictions arise. Regarding other configurations, the embodiments disclosed in this specification are merely examples in all respects. Therefore, various modifications may be made as appropriate within the scope of the present disclosure.

[0073] [Summary of the above embodiment] The following describes the operating equipment for the unmanned aerial vehicle described above.

[0074] The rotary-wing unmanned aerial vehicle of the present disclosure is formed to extend in the vertical direction and is equipped with a passage space through which the unmanned aerial vehicle ascends or descends, and an air pressure control system that controls the air pressure within the passage space, and the air pressure control system controls the air pressure above the unmanned aerial vehicle to be lower than the air pressure below the unmanned aerial vehicle.

[0075] According to this configuration, the air pressure above the unmanned aircraft is lower than the air pressure below the unmanned aircraft, making it easier for the unmanned aircraft to secure lift. This makes it easier to stabilize the flight of the unmanned aircraft. Furthermore, since the energy consumption required for the unmanned aircraft to secure lift can be reduced, it is easier to improve the energy efficiency of the flight of the unmanned aircraft.

[0076] In one aspect, the air pressure control system preferably includes at least one of an exhaust unit provided in an upper part of the passage space to exhaust air from the passage space, and an air supply unit provided in a lower part of the passage space to supply air to the passage space.

[0077] With this configuration, the air pressure around the unmanned aerial vehicle within the passage space can be appropriately controlled.

[0078] In one aspect, the air pressure control system comprises an exhaust unit provided at an upper part of the passage space for exhausting air from the passage space, and an air supply unit provided at a lower part of the passage space for supplying air to the passage space, and the passage space is preferably arranged to penetrate a partition wall that separates different floors, and is formed by being surrounded by a cylindrical wall extending in the vertical direction, and the exhaust unit and the air supply unit are preferably arranged to penetrate the cylindrical wall.

[0079] According to this configuration, the exhaust unit is arranged to connect the inside and outside of the passage space, and the air supply unit is arranged to connect the inside and outside of the passage space, making it easier to appropriately control the air pressure in the passage space using the air pressure control system.

[0080] In one embodiment, the air pressure control system preferably lowers the exhaust pressure of the exhaust unit when the unmanned aerial vehicle passes through a first area, which is the vertical area in the passage space where the exhaust unit is located, compared to before the unmanned aerial vehicle entered the first area, and lowers the supply pressure of the air supply unit when the unmanned aerial vehicle passes through a second area, which is the vertical area in the passage space where the air supply unit is located, compared to before the unmanned aerial vehicle entered the second area.

[0081] This configuration reduces the possibility that a drop in air pressure caused by the exhaust unit will adversely affect the flight of the unmanned aircraft when the unmanned aircraft passes through the first area, and reduces the possibility that a rise in air pressure caused by the air supply unit will adversely affect the flight of the unmanned aircraft when the unmanned aircraft passes through the second area. Therefore, it is easy to stabilize the flight state of the unmanned aircraft even when the unmanned aircraft passes through both the first and second areas.

[0082] In one embodiment, the air pressure control system comprises a first detection unit that detects the unmanned aerial vehicle's approach to the first area and a second detection unit that detects the unmanned aerial vehicle's approach to the second area, and it is preferable that the air pressure control system determines that the unmanned aerial vehicle will pass through the first area based on the detection of the unmanned aerial vehicle by the first detection unit, and determines that the unmanned aerial vehicle will pass through the second area based on the detection of the unmanned aerial vehicle by the second detection unit.

[0083] With this configuration, it is possible to appropriately determine when the unmanned aerial vehicle passes through the first area and when the unmanned aerial vehicle passes through the second area.

[0084] In one aspect, an opening / closing door that divides the passage space in the vertical direction is provided at least at the lower part of the passage space, and it is preferable that the opening / closing door is opened when the unmanned aerial vehicle passes through and closed after the unmanned aerial vehicle has passed through.

[0085] According to this configuration, even if the unmanned aerial vehicle crashes inside the passage space, it is easy to prevent the unmanned aerial vehicle from falling below the passage space. Also, when it is undesirable for gas to flow vertically through the passage space, such a flow can be restricted.

[0086] In one aspect, the air pressure control system includes a position information acquisition unit that acquires position information indicating the position of the unmanned aerial vehicle, and an air pressure detection unit that detects air pressure at multiple locations in the vertical direction in the passage space, and it is preferable to control the air pressure in the passage space based on the position information acquired by the position information acquisition unit and the detection results of the air pressure detection unit.

[0087] According to this configuration, the air pressure above the unmanned aircraft can be appropriately controlled to be lower than the air pressure below the unmanned aircraft, depending on the position of the unmanned aircraft.

[0088] In one aspect, the passage space is preferably formed in a columnar shape that is inclined toward one side in the horizontal direction as it extends downward.

[0089] This configuration makes it easier to avoid the vortex ring state, in which a rotary-wing unmanned aerial vehicle falls into its own downwash and loses lift, when descending, and therefore makes it easier to stabilize the flight state of the unmanned aerial vehicle when descending.
