Description

Technical Field

[0001] The present application relates to the field of wireless charging technology for unmanned aerial vehicles, and in particular to a charging and battery replacement system for unmanned aerial vehicles based on wireless charging technology. Background Art

[0002] Drones can collect and process data quickly, efficiently and accurately by carrying a variety of sensors, and have important application value in urban traffic patrols, power facility inspections and rapid logistics transportation. However, due to the limitations of size and battery capacity, the endurance of drones has always been an important problem restricting their development and application. The existing charging methods of drones have the following problems:

[0003] First, the method of charging the drone after landing is slow and time-consuming, so it is not suitable for scenarios with high energy consumption and high frequency of deployment.

[0004] Secondly, replacing drone batteries manually requires high labor costs, is inefficient, and has large limitations, making it unsuitable for unmanned scenarios. How to achieve rapid power replenishment for large numbers of drones under unmanned conditions has become a technical challenge in this field. In order to ensure the continuity of drone operations and improve the utilization rate of drones, the battery replacement solution is more advantageous than the charging solution. In a Chinese invention patent entitled "An Unmanned Battery Replacement Station for Power Inspection Drones" with the authorization announcement number CN113276725B, a drone battery replacement station in an unmanned scenario is proposed, but the invention fails to solve the problem of exposed drone battery contacts. The drone battery replacement station proposed in the invention cannot adapt to complex environments. For example, if used in rainy and snowy weather, it will cause a short circuit in the entire battery replacement system. In addition, the exposed battery contacts are easily damaged, resulting in poor contact of the battery replacement system.

[0005] Therefore, it is necessary to propose a solution to improve one or more problems existing in the above-mentioned related technical solutions.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0053] Multiple drones, all of which are equipped with a main battery box and a secondary battery. The main battery box is a disposable battery box with a main battery inside. The drones are docked with the main battery box by electromagnetic induction.

[0054] The drone battery replacement area includes multiple parking lots, each of which only allows one drone to park during the same charging time;

[0058] Among them, all drones, drone battery replacement areas, battery charging areas, battery storage areas and all discarded main battery boxes are communicated and connected with each other; a first transportation path is set between the drone battery replacement area and the battery charging area, and a second transportation path is set between the battery storage area and the drone battery replacement area; and transportation channels are set in the battery charging area and the battery storage area.

[0059] The present application embodiment proposes a drone charging and battery replacement system based on wireless charging technology, which has at least the following beneficial effects:

[0060] (1) The present application provides a UAV battery replacement area, which includes multiple parking aprons; provides a battery charging area, which includes multiple charging positions; provides a battery storage area, which includes multiple storage positions; and controls the charging and battery replacement process of the UAVs through a control device, thereby realizing rapid power replenishment of a large number of UAVs and improving the charging efficiency of the UAVs;

[0061] (2) The present application avoids the problem of exposed battery contacts by designing the main battery box to be disposable, removable, and rechargeable;

[0062] (3) The present application achieves wireless charging during the charging and powering process of the drone by designing the drone and the main battery box to dock via electromagnetic induction, and docking the charging position with the main battery box via electromagnetic induction.

[0063] A drone charging and battery replacement system based on wireless charging technology proposed in this example embodiment is now described in more detail.

[0064] This application adopts the design concept of "battery dispatching at battery swap stations and autonomous battery swapping by drones". Figure 1 It can be seen that this application divides the entire base station into different functional areas, including:

[0065] Drone battery replacement area, multiple helipads are set up in the drone battery replacement area. The drone battery replacement area is marked with H, and all helipads are marked with H combined with Arabic numerals. In this embodiment, 6 helipads are set up in the drone battery replacement area, marked as H1, H2, H3, H4, H5 and H6 in sequence. Figure 1 It can be seen that each apron is provided with an exit above, all of which are connected to the first transport path, and the main battery box to be charged is driven out from the exit and moved to the vacant charging position in the battery charging area via the first transport path. Each apron is provided with an entrance below, all of which are connected to the second transport path, and the fully charged main battery box is driven into the apron through the entrance via the second transport path.

[0066] Battery charging area, multiple charging positions are set in the battery charging area. The battery charging area is marked with C, and all charging positions are marked with C combined with Arabic numerals. In this embodiment, 6 charging positions are set in the battery charging area, which are marked as C1, C2, C3, C4, C5 and C6 in sequence. Figure 1 It can be seen that the battery charging area is connected to the first transport path and to the battery storage area, that is, a transport channel is provided.

[0067] The battery storage area has multiple storage locations. The battery storage area is marked with B, and all storage locations are marked with B combined with Arabic numerals. In this embodiment, 9 storage locations are set in the battery storage area, which are marked as B1, B2, B3, B4, B5, B6, B7, B8 and B9. Figure 1 It can be seen that the battery storage area is connected to the second transport path, and the fully charged main battery box is driven into the apron from the entrance via the second transport path.

[0068] Furthermore, the provision of different transport paths and channels can prevent congestion and collision during the movement of the main battery box.

[0069] Control device, by Figure 1 It can be seen that the entire base station is covered by WIFI signals, and all main battery boxes and nearby drones will automatically be assigned corresponding IP addresses and identifiers to access the intranet. The entire base station is uniformly controlled and dispatched by the control device. Different functional areas are assigned different identifiers and independent names. For example, the drone battery replacement area mentioned above is identified as H, the battery charging area is identified as C, and the battery storage area is identified as B. The paths between different functional areas are fixed. The control device only needs to send instructions to different functional areas to the movable main battery box, and the main battery box will move along a unique path.

[0070] In one embodiment, Figure 2 and Figure 3 As shown in the figure, within the entire base station, the process of charging and replacing the battery of the drone includes the following steps:

[0071] Step S101: The drone flies above the helipad, connects to the intranet and hovers at a preset height.

[0072] Step S102: The power subsystem inside the drone switches the power source to the secondary battery as power input, and relies on the secondary battery to keep the drone in a hovering state.

[0073] Furthermore, in order to meet the needs of rapid battery replacement for drones, the power layout of drones needs to be adjusted. Since the drone needs to maintain a short hovering state after dropping the main battery box, in addition to the main battery with a large capacity, the drone also needs to be equipped with a small onboard battery as a secondary battery. The two batteries can be switched autonomously by the drone, and after the entire battery replacement process of the drone is completed, the main battery box can supply power to the secondary battery.

[0074] Furthermore, if Figure 4As shown, the main battery box of the drone is provided with a main battery, an inverter and a rectifier and voltage regulator, and the auxiliary battery is used as an onboard battery. The single-pole double-throw switch S1 and the switch S2 are used for switching the connection between the main battery box and the auxiliary battery and the power subsystem of the drone. When the single-pole double-throw switch S1 is closed downward, the switch S2 is disconnected. At this time, the main battery box is connected to the power subsystem of the drone, and the main battery box supplies power to the power subsystem of the drone; when the single-pole double-throw switch S1 is closed upward, the switch S2 is closed. At this time, the auxiliary battery supplies power to the power subsystem of the drone. At the same time, the main battery box can charge the auxiliary battery until the auxiliary battery is fully charged. The voltage stabilizing capacitor is used to filter the voltage fluctuations during the switching process. Therefore, by controlling the switching of different switches by the drone, the switching between the main battery and the auxiliary battery and the energy replenishment can be realized.

[0075] Step S103: After the control device detects the stability of the hovering state of the drone, the main battery box to be charged is dropped.

[0076] Step S104: the control device controls the main battery box to move along the first transport path to an idle charging position for charging. After the main battery box is fully charged, the control device controls the fully charged main battery box to move to an idle storage position.

[0077] Furthermore, if Figure 5a , Figure 5b and Figure 5c As shown, in order to realize wireless charging and mobility of the main battery box 100, the internal and external structures of the main battery box 100 are specifically designed in this embodiment.

[0078] The main battery box 100 includes:

[0079] The housing 110 is provided with a housing cover 120, a first charging coil 111 is provided on the bottom inner end surface of the housing 110, one end of the first charging coil 111 is connected to the bottom inner end surface of the housing 110, and the other end of the first charging coil 111 is connected to the first shielding ferrite 112; a plurality of driving wheels 113 are provided at the lower end of the housing 110; a pair of corresponding hangers 114 are provided on both sides of the housing 110;

[0080] A second discharge coil 121 is disposed on the inner end surface of the shell cover 120, the upper end of the second discharge coil 121 is connected to the inner end surface of the shell cover 120, and the lower end of the second discharge coil 121 is connected to a second shielding ferrite 122;

[0081] Various sensing components, all of which are arranged at the head of the housing 110;

[0082] Further, in this embodiment, the multiple sensing elements are preferably an inductance array 115 and two ultrasonic probes 116 disposed at the head of the housing 110, and the two ultrasonic probes 116 are disposed symmetrically below the inductance array 115. The inductance array 115 has the function of detecting electromagnetic signals to guide the main battery box 100. The ultrasonic probe 116 is used to detect echo signals, thereby enabling the main battery box 100 to avoid obstacles.

[0083] A signal receiving element 117, which is disposed at the rear of the housing 110;

[0084] In which, in the space formed by the shell 110 and the shell cover 120, a main battery 130 is arranged between the first shielding ferrite 112 and the second shielding ferrite 122, and there is a gap between the main battery 130 and the first shielding ferrite 112 and the second shielding ferrite 122 respectively; in this embodiment, the main battery 130 is preferably a lithium polymer battery.

[0085] In the shell 110, an inverter 140 and a rectifier and voltage stabilizer 150 are arranged at one end close to the head of the shell 110, and the inverter 140 and the rectifier and voltage stabilizer 150 are respectively connected to the main battery 130. A central processing unit 160 is arranged at one end close to the tail of the shell 110, and the central processing unit 160 is respectively connected to the first charging coil 111, the second discharging coil 121, all inductive components, the signal receiving component 117, the inverter 140 and the rectifier and voltage stabilizer 150.

[0086] Furthermore, a first discharge coil is provided at each charging position, and a power supply device is connected to the lower end of the first discharge coil. The first discharge coil and the first charging coil 111 realize wireless charging of the main battery 130 by electromagnetic induction.

[0087] Furthermore, the bottom of the drone 200 is provided with a second charging coil 210. A third shielding ferrite 220 is provided at the lower end of the second charging coil 210. After the drone 200 is locked and connected with the fully charged main battery box 100, the second discharge coil 121 and the second charging coil 210 realize wireless charging of the drone 200 by electromagnetic induction.

[0088] Further, by Figure 6As shown, the main battery 130 converts direct current into high-frequency alternating current through the inverter 140 and the resonant circuit, and generates a high-frequency electromagnetic field through the second discharge coil 121. The arrangement of the first shielding ferrite 112, the second shielding ferrite 122 and the third shielding ferrite 220 can constrain the electromagnetic field between the coils, thereby improving the electromagnetic coupling coefficient and the efficiency of the coil energy transfer. After the second charging coil 210 of the drone 200 receives the high-frequency electromagnetic field, it is compensated and adjusted through the resonant circuit of the drone 200 to generate high-frequency alternating current, which is converted into stable direct current through the rectifier and voltage regulator device 150 of the drone 200 to supply the power subsystem of the drone 200.

[0089] Step S105: The control device controls the fully charged main battery box in the battery storage area to move to the apron below the drone to be replaced.

[0090] Step S106: The drone uses the bracket to lock and connect with the fully charged main battery box, and the power subsystem switches the power source to the main battery box as the power input, completing the charging and battery replacement process of the drone.

[0091] The principle of the entire charging and battery replacement process of the drone is as follows Figure 7 As shown, the drone navigates to the base station based on Beidou positioning. The drone saves the configuration information and password of the base station network. After identifying the networking WIFI and SSID of the base station, it will automatically connect and send a battery replacement request. After the base station receives the drone's battery replacement request, the control device traverses the entire drone battery replacement area starting from the position of H1. If the helipad is occupied, the control device displays the location of the helipad as 1, otherwise it displays as 0. The base station determines the unoccupied helipad, sends the location of the helipad to the drone, and turns on the indicator light of the helipad to assist the drone's electronic map to guide the drone to be replaced to the top of the helipad. Figure 7 The battery swap station is the base station.

[0092] At the same time, the base station traverses the battery charging area and the battery storage area respectively to determine the free charging position and the storage position of the main battery box with full charge. When the main battery box flies into the designated apron, the control device of the base station turns on the electromagnetic guidance of the only path from the battery storage area to the apron, guides the fully charged main battery box to the designated apron, and then turns off the guidance. The drone arrives at the designated apron, lowers to the hovering height, drops the main battery box, and sends status information to the control device. The control device turns on the only path guidance from the apron to the battery charging area, and the dropped main battery box to be charged relies on electromagnetic guidance to move to the designated charging position and perform wireless charging. The drone identifies the position of the fully charged main battery box, relies on the short power provided by the auxiliary battery, lands on the fully charged main battery box for locking and docking, and completes the entire charging and battery replacement process of the drone.

[0093] The drone charging and battery replacement system based on wireless charging technology proposed in this application, first of all, can avoid the ablation problem caused by the exposed charging contacts of the battery through the special design of the main battery box and wireless charging technology; secondly, this application adopts the idea and battery replacement scheduling method of Daxian battery replacement station, which can simultaneously replace the batteries of a large number of drones, greatly improving the efficiency of power replacement of drones; finally, the special design of the main battery box makes it movable, so that it can replace the landing gear of the drone, and can also guide charging by itself, thereby realizing the automatic replacement and safe charging of the drone battery.
