Description

Technical Field

[0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a machine nest capable of accommodating multiple unmanned aerial vehicles and a control system thereof. Background Art

[0002] With the development of wireless communication technology, aerial remote sensing mapping technology, GPS navigation and positioning technology, and automatic control technology, drones have gradually been widely used in infrastructure planning, line inspection, emergency response, terrain measurement and other fields. In order to facilitate the landing of drones, machine nests that can hold multiple drones have come into being. The landing platform set up in the machine nest can facilitate the lifting and storage of multiple drones.

[0003] However, during the take-off and landing process of drones, some drones will generate strong winds around them, which may affect other parked drones and may cause other drones to fail to take off smoothly during subsequent take-offs.

[0004] Therefore, how to provide an effective solution to prevent the strong wind generated during the lifting of the UAV and the impact on the take-off of other UAVs has become a difficult problem to be solved in the prior art. Summary of the invention

[0005] The purpose of the present invention is to provide a machine nest capable of accommodating multiple UAVs and a control system thereof, so as to solve the above-mentioned problems existing in the prior art.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] In the first aspect, the present invention provides a machine nest capable of accommodating multiple drones, comprising a plurality of sub-parking nests, wherein the sub-parking nests comprise a trough, a parking platform, a lifting mechanism, a transmission gear set and an upper cover, wherein the upper cover is slidably matched with the opening of the trough, the lifting mechanism and the parking platform are both arranged in the trough, the lifting mechanism is used to drive the parking platform to rise / descend in the trough, a first rack is arranged on the side of the lifting mechanism, a second rack is arranged on the side of the upper cover facing the trough, the transmission gear set is respectively connected to the first rack and the second rack in transmission, and drives the upper cover to open when the parking platform rises in the trough, and drives the upper cover to close when the parking platform descends in the trough.

[0008] Based on the above - disclosed content, the drone nest capable of placing multiple drones provided by the present invention is provided with multiple sub - parking nests. Each sub - parking nest includes a sunken groove, a parking platform, a lifting mechanism, a transmission gear set, and an upper cover. The upper cover is slidably engaged with the opening of the sunken groove. The lifting mechanism and the parking platform are both arranged in the sunken groove. The lifting mechanism is used to drive the parking platform to rise / fall in the sunken groove. A first rack is arranged on the side of the lifting mechanism, and a second rack is arranged on the side of the upper cover facing the sunken groove. The transmission gear set is respectively in transmission connection with the first rack and the second rack, and drives the upper cover to open when the parking platform rises in the sunken groove, and drives the upper cover to close when the parking platform falls in the sunken groove. In this way, when a drone lands in the sub - parking nest, the lifting mechanism can be used to drive the parking platform to descend in the sunken groove, and the transmission gear set can be used to drive the upper cover to close, so as to store the drone in a closed space. When a new drone lands, the generated wind will not affect the stored drones, thus ensuring that the stored drones can take off smoothly during subsequent take - off. When the stored drone needs to take off, the lifting mechanism can be used to drive the parking platform to rise in the sunken groove, and the transmission gear set can be used to drive the upper cover to open, so as to take out the drone that needs to take off, while other drones that do not need to take off are still stored in a closed space, thus not affecting other drones, and ensuring that the stored drones can take off smoothly during subsequent take - off.

[0009] In a possible design, the transmission gear set includes a first transmission gear and a second transmission gear. The first transmission gear is respectively in transmission connection with the first rack and the second transmission gear, and the second transmission gear is in transmission connection with the second rack.

[0010] In a possible design, the lifting mechanism is a cylinder.

[0011] In a possible design, the parking platform includes a parking platform main body and a parking board. The parking platform main body is connected to the lifting mechanism, and a pressure sensor is arranged between the parking platform main body and the parking board.

[0012] In a possible design, an installation groove is arranged on the parking platform main body, and the parking board is arranged in the installation groove.

[0013] In a possible design, the number of sub - parking nests is 4, and the 4 sub - parking nests are arranged in a "field" shape.

[0014] In a possible design, a wireless charging unit is arranged at the bottom of the sunken groove.

[0015] In the second aspect, the present invention discloses a machine nest control system that can accommodate multiple drones, which is used to control any machine nest that can accommodate multiple drones as described in the first aspect, including a controller and multiple pressure sensors corresponding to the multiple sub-parking nests one by one, the controller is electrically connected to the multiple pressure sensors and the lifting mechanisms of the multiple sub-parking nests, respectively, the pressure sensors are arranged in the parking platforms of the corresponding sub-parking nests, the controller is used to determine whether the multiple sub-parking nests have drones parked according to the pressure signals detected by the multiple pressure sensors, the controller is also used to detect the lifting state of the lifting mechanism of the multiple sub-parking nests, and when there is a target sub-parking nest whose lifting state of the lifting mechanism is the rising limit state, and the target sub-parking nest has a drone parked, the lifting mechanism of the target sub-parking nest is controlled to descend to the descending limit state.

[0016] In one possible design, the controller is used to control the lifting mechanism of one of the sub-parking nests where no drone is parked to rise when there is a sub-parking nest where no drone is parked, so as to park the drone through the sub-parking nest where no drone is parked.

[0017] In one possible design, a control system for a machine nest that can accommodate multiple drones also includes a server, which is communicatively connected to the controller. The server is used to send a control signal to the controller so that the controller controls the rise / descent of the lifting mechanisms of the multiple sub-machine nests based on the control signal.

[0018] Beneficial effects:

[0019] The machine nest capable of accommodating multiple drones and the control system thereof provided by the present invention can store the parked drones in a closed space so that the landing or taking-off of the drones will not affect other drones, thereby ensuring that the stored drones can take off smoothly during the subsequent take-off process, which is convenient for practical application and promotion.

[0030] like Figure 1-3As shown, the first aspect of the embodiment of the present application provides a nest capable of accommodating multiple drones, and the nest capable of accommodating multiple drones includes multiple sub-nests 10, each of which can be used to lift drones. The sub-nest 10 includes a sink 11, a parking platform 12, a lifting mechanism 13, a transmission gear set 14 and an upper cover 15, the upper cover 15 is slidably matched with the opening of the sink 11, the lifting mechanism 13 and the parking platform 12 are both arranged in the sink 11, and the lifting mechanism 13 is used to drive the parking platform 12 to rise / fall in the sink 11.

[0031] The upper cover 15 is slidably matched with the opening of the sink 11. Specifically, a limiting groove is provided on the edge of the upper cover 15 facing the sink 11, and a limiting convex strip is provided at the opening of the sink 11. The limiting groove and the limiting convex strip are slidably matched, so that the upper cover 15 can be used to slide along the direction of the limiting groove to open or close the sink 11.

[0032] The lifting mechanism 13 is used to drive the parking platform 12 to rise / fall in the sink 11. Figure 3 As shown, a first rack (not shown) is provided on the side of the lifting mechanism 13, a second rack (not shown) is provided on the side of the upper cover 15 facing the sink 11, and a transmission gear set 14 is respectively connected to the first rack and the second rack, and drives the upper cover 15 to open when the parking platform 12 rises in the sink 11, and drives the upper cover 15 to close when the parking platform 12 descends in the sink 11. Specifically, the transmission gear set 14 includes a first transmission gear 141 and a second transmission gear 142, the first transmission gear 141 is respectively connected to the first rack and the second transmission gear 142, and the second transmission gear 142 is connected to the second rack.

[0033] The lifting mechanism 13 is used to drive the parking platform 12 to rise / fall in the sink 11, and it can be, but is not limited to, a lifting mechanism 13 of a screw rod, a cylinder, or a motor plus a gear rack. In the embodiment of the present application, the lifting mechanism 13 is a cylinder.

[0034] When it is necessary to park and store drones through a drone nest that can accommodate multiple drones, the drones can be controlled to park on the parking platform 12 of one of the sub-drone nests 10. Then, the lifting mechanism 13 of the one sub-drone nest 10 can be controlled to drive the parking platform 12 to descend. When the parking platform 12 descends, the upper cover 15 is gradually driven to close through the transmission gear set 14, and finally the drones are stored in a closed space. When new drones land, the generated wind will not affect the stored drones, thus ensuring that the stored drones can take off smoothly during subsequent takeoff. When the stored drones need to take off, the lifting mechanism 13 can be used to drive the parking platform 12 to rise in the sinking groove 11. During the rising process of the parking platform 12, the upper cover 15 is gradually driven to open through the transmission gear set 14, so as to take out the drones that need to take off, while the other drones that do not need to take off are still stored in the closed space, thus not affecting the other drones, and ensuring that the stored drones can take off smoothly during subsequent takeoff.

[0035] As Figure 4 shown, in one or more embodiments, the parking platform 12 includes a parking platform main body 121 and a parking board 122. The parking platform main body 121 is connected to the lifting mechanism 13. The parking board 122 is used for parking drones. A pressure sensor is arranged between the parking platform main body 121 and the parking board 122. Specifically, an installation groove is arranged on the parking platform main body 121, the parking board 122 is arranged in the installation groove, and the pressure sensor is arranged in the installation groove and located between the parking board 122 and the parking platform main body 121. One or more pressure sensors can be arranged. In the embodiment of the present application, there are multiple pressure sensors. By arranging the pressure sensor, it is convenient and accurate to detect whether there are drones parked on each sub-drone nest 10 according to the pressure value detected by the pressure sensor, so as to facilitate the storage of drones parked on the sub-drone nest 10.

[0036] The number of sub-drone nests 10 is multiple and can be set according to actual situations. In the embodiment of the present application, the number of sub-drone nests 10 is 4, and the 4 sub-drone nests 10 are arranged in a "field" shape.

[0037] In one or more embodiments, a wireless charging unit is arranged at the bottom of the sinking groove 11. Through the wireless charging unit, drones with wireless charging functions can be charged to ensure the endurance of the drones.

[0038] In summary, the machine nest provided by the present invention can accommodate multiple drones by setting up multiple sub-parking nests 10, and the sub-parking nests 10 include a trough 11, a parking platform 12, a lifting mechanism 13, a transmission gear set 14 and an upper cover 15. The upper cover 15 is slidably matched with the opening of the trough 11, and the lifting mechanism 13 and the parking platform 12 are both arranged in the trough 11. The lifting mechanism 13 is used to drive the parking platform 12 to rise / descend in the trough 11. A first rack is arranged on the side of the lifting mechanism 13, and a second rack is arranged on the side of the upper cover 15 facing the trough 11. The transmission gear set 14 is respectively connected to the first rack and the second rack, and drives the upper cover 15 to open when the parking platform 12 rises in the trough 11, and drives the upper cover 15 to close when the parking platform 12 descends in the trough 11. In this way, after the drone lands on the sub-parking nest 10, the parking platform 12 can be driven to descend in the sink 11 by the lifting mechanism 13, and the upper cover 15 can be driven to close by the transmission gear set 14, so that the drone is stored in a closed space. When a new drone lands, the wind force generated will not affect the stored drone, thereby ensuring that the stored drone can take off smoothly during the subsequent take-off process. When the stored drone needs to take off, the parking platform 12 can be driven to rise in the sink 11 by the lifting mechanism 13, and the upper cover 15 can be driven to open by the transmission gear set 14, so that the drone that needs to take off can be taken out, while other drones that do not need to take off are still stored in the closed space, so as not to affect other drones, thereby ensuring that the stored drone can take off smoothly during the subsequent take-off process. In addition, a pressure sensor is provided between the parking platform body 121 and the parking plate 122, so as to facilitate and accurately detect whether there is a drone parked on each sub-parking nest 10, so that the drone can be parked on the sub-parking nest 10 for storage. In addition, by arranging a wireless charging unit at the bottom of the sink 11, a drone with a wireless charging function can be charged to ensure the drone's endurance.

[0039] See also Figure 5 The second aspect of the embodiment of the present application provides a machine nest control system that can accommodate multiple drones, which is used to control the machine nest that can accommodate multiple drones as described in the first aspect. The machine nest control system that can accommodate multiple drones includes a controller and multiple pressure sensors corresponding to multiple sub-parking nests one by one. The controller is electrically connected to the multiple pressure sensors and the lifting mechanisms of the multiple sub-parking nests, respectively, and the pressure sensors are arranged in the parking platforms of the corresponding sub-parking nests.

[0040] Among them, the controller is used to determine whether there are drones parked in multiple sub-parking nests based on pressure signals detected by multiple pressure sensors. The controller is also used to detect the lifting status of the lifting mechanisms of the multiple sub-parking nests, and when there is a target sub-parking nest whose lifting status of the lifting mechanism is the rising limit state (i.e., rising to the highest state), and there is a drone parked in the target sub-parking nest, the lifting mechanism of the target sub-parking nest is controlled to descend to the descending limit state (i.e., descending to the lowest state).

[0041] By setting a controller and multiple pressure sensors, the pressure signal detected by the pressure sensor can be used for judgment. If the pressure signal detected by the pressure sensor is greater than the preset pressure threshold, it can be determined that a drone is parked in the parking nest corresponding to the pressure sensor. At the same time, the controller determines the lifting state of the lifting mechanism of multiple sub-parking nests. If there is a target sub-parking nest whose lifting state is the rising limit state (target sub-parking nest), and a drone is parked in the target sub-parking nest, it is determined that a drone is parked on the target sub-parking nest. At this time, the lifting mechanism of the target sub-parking nest can be controlled to descend. During this process, the drone slowly descends with the lifting mechanism. At the same time, the lifting mechanism drives the upper cover of the target sub-parking nest to close through the transmission gear set, thereby storing the drone in a closed space until the lifting mechanism descends to the descending limit state. When a new drone lands, the wind force generated will not affect the stored drone, thereby ensuring that the stored drone can take off smoothly during the subsequent take-off process.

[0042] In a possible design, the controller is used to control the lifting mechanism of one of the sub-parking nests without a drone parked to rise when there is a sub-parking nest without a drone parked, so as to park a drone through one of the sub-parking nests without a drone parked. In this way, when the drones are not fully parked, a sub-parking nest without a drone parked can be automatically provided to facilitate the parking and storage of drones.

[0043] In a possible design, the control system of the machine nest capable of accommodating multiple drones further includes a server, which is communicatively connected to the controller, and is used to send a control signal to the controller so that the controller controls the ascent / descent of the lifting mechanisms of the multiple sub-machine nests according to the control signal. By setting up the server, the machine nest capable of accommodating multiple drones can be remotely controlled by the server.

[0044] In summary, the nest control system for accommodating multiple drones provided by the present invention can store the parked drones in a closed space, so that the drones that are landing or taking off will not affect other drones, thereby ensuring that the stored drones can take off smoothly during the subsequent take-off process. At the same time, when the drones are not fully parked, a sub-parking nest for unparked drones can be automatically provided to the outside to facilitate the parking and storage of drones. In addition, a server is set up to facilitate remote control of the nest that can accommodate multiple drones through the server.
