Summary of the Invention

Problems to be Solved by the Invention

[0004] The robot charging device operated by the above system is connected to an aircraft parked at a predetermined departure / arrival port or boarding / alighting area to charge the aircraft. Therefore, when the aircraft moves between the departure / arrival port and the boarding / alighting area, it is necessary to disconnect and reconnect the connection between the robot charging device and the aircraft, resulting in poor efficiency. In addition, since the charging of the aircraft is interrupted while the aircraft is moving, there is room for improvement in more efficiently using the period when the aircraft is waiting on the ground to supply power to the aircraft. The present invention has been made in view of such a background, and an object thereof is to provide a power supply device and a power supply management system that can efficiently supply power to a flying object that moves between a plurality of areas while waiting on the ground.

Means for Solving the Problems

[0005] As a first embodiment for achieving the above objective, the system comprises: a first storage battery; a running unit that operates and moves using power supplied from the first storage battery; a pad mounted on the running unit on which a vertical take-off and landing type aircraft is placed; a power supply unit that supplies power output from the first storage battery to the aircraft placed on the pad; a movement plan recognition unit that recognizes the movement plan of the aircraft; a second storage battery state recognition unit that recognizes the state of a second storage battery provided in the aircraft; and a power supply control unit that controls the first power supplied from the first storage battery to the running unit and the second power supplied from the first storage battery to the aircraft via the power supply unit, based on the movement plan recognized by the movement plan recognition unit and the state of the second storage battery recognized by the second storage battery state recognition unit. The power supply control unit determines the amount of the second power to be supplied based on the power required to charge the second battery provided in the aircraft, and the power required to operate the battery temperature control unit provided in the aircraft for heating or cooling the second battery. Power supply devices are one example.

[0006] In the above-described power supply device, the power supply control unit may be configured to determine the amount of the first power to be supplied based on the power required to place the aircraft on the pad and move it between predetermined points using the running unit between flights.

[0008] In the above-described power supply device, the travel plan may be configured to include a departure time, departure point, arrival time, arrival point, and ground travel points. [Effects of the Invention]

[0010] According to the above-described power supply device and power supply management system, power can be efficiently supplied to an aircraft moving between multiple areas while it is stationary on the ground. [Brief explanation of the drawing]

[0011] [Figure 1] Figure 1 is a diagram showing the configuration of the power supply device. [Figure 2] Figure 2 is an explanatory diagram illustrating how the power supply management system manages the power supply to aircraft. [Figure 3]Figure 3 is a diagram showing the configuration of the power supply management system. [Figure 4] Figure 4 is a flowchart of the power supply device selection process by the power supply management system. [Figure 5] Figure 5 is a flowchart of the power supply control process by the power supply device. [Modes for carrying out the invention]

[0012] [1. Configuration of the power supply device] Referring to Figure 1, the configuration of the power supply device 1 of this embodiment will be described. The power supply device 1 comprises a trolley section 10 and a pad 40 mounted on the trolley section 10. A vertical take-off and landing type aircraft 50, such as a VTOL aircraft (Vertical Take-Off and Landing aircraft), is placed on the pad 40, and the pad 40 is equipped with a fixing device 42 for securing the aircraft 50 and a power supply arm 41 that is connected to the charging port 51 of the aircraft 50 and supplies power to the aircraft 50. The power supply device 1 may also be provided with a function for placing the aircraft 50 on the pad 40.

[0013] The aircraft 50 is equipped with a second battery 52 which is a power source for the rotor 57 and the like, a battery temperature control unit 53 which heats or cools the second battery 52 to maintain the temperature of the second battery 52 within an appropriate temperature range, a battery sensor 54 which detects the state of the second battery 52 (voltage, current, temperature, etc.), a control unit 55, and a communication unit 56.

[0014] The second battery 52 is charged by power supplied from the charging port 51. The battery temperature control unit 53 operates using power supplied from the second battery 52 or power supplied from the charging port 51. The aircraft 50 may be an electric aircraft that uses only the second battery 52 as its power source, or it may be a hybrid aircraft equipped with a generator operated by a gas turbine or the like in addition to the second battery 52. ​​If the aircraft 50 is a hybrid, the second battery 52 may be powered by the electricity generated by the generator.

[0015] The trolley section 10 of the power supply device 1 is equipped with a first battery 11, a battery temperature adjustment unit 12 that heats or cools the first battery 11 to maintain its temperature within an appropriate range, a battery sensor 13 that detects the state of the first battery 11 (voltage, current, temperature, etc.), a power supply unit 14 that supplies power output from the first battery 11 to the aircraft 50 via a power supply arm 41, a communication unit 15, a running unit 16, and a control unit 17. The first battery 11 is charged by a charging device connected to a charging port 18.

[0016] The running section 16 consists of an electric motor 16a that operates using power supplied from the first battery 11, drive wheels 16b driven by the electric motor 16a, the frame of the bogie section 10, etc., and moves the power supply device 1. The power supply device 1 may be operated by a driver or it may travel automatically. When the power supply device 1 travels automatically, it travels while recognizing its surroundings using cameras, radar, etc. (not shown).

[0017] The control unit 17 is a computer unit equipped with a processor 20, memory 30, etc. The memory 30 stores the control program 31 for the power supply device 1 and movement plan data 32 which records movement plan information indicating the movement plan of the aircraft 50. The movement plan includes the aircraft 50's next departure point, departure time, destination, arrival time, and planned movement between waiting areas.

[0018] The processor 20 functions as a movement plan recognition unit 21, a first battery state recognition unit 22, a second battery state recognition unit 23, a power supply control unit 24, and a driving control unit 25 by reading and executing the control program 31. The movement plan recognition unit 21 accesses the aircraft database 211 (described later) to obtain the movement plan information MVP of the aircraft 50 and records the obtained movement plan information MVP 32 in the movement plan data 32.

[0019] The first battery state recognition unit 22 recognizes the state (such as the power storage amount, temperature, etc.) of the first battery 11 based on the detection information of the battery sensor 13, and transmits the first battery state information BC1 indicating the state of the first battery 11 to the power supply management system 100 described later. The second battery state recognition unit 23 receives the second battery state information BC2 transmitted from the aircraft 50, and recognizes the state (such as the power storage amount, temperature, etc.) of the second battery 52 from the second battery state information BC2.

[0020] The power supply control unit 24 controls the amount of power of the second power supplied to the aircraft 50 based on the movement plan of the aircraft 50 and the state of the second battery 52, so as to ensure the charging of the second battery 52 required for the flight of the aircraft 50 according to the movement plan of the aircraft 50 and the operation of the battery temperature adjustment unit 53 during the standby of the aircraft 50 on the ground.

[0021] Also, the power supply control unit 24 controls the amount of power of the first power supplied to the traveling unit 16 when the power supply device 1 travels with the aircraft 50 placed thereon based on the movement plan of the aircraft 50. The traveling control unit 25 operates the traveling unit 16 with the first power controlled by the power supply control unit 24 to make the power supply device 1 travel.

[0022] [2. Configuration of Power Supply Management System] Referring to FIGS. 2 and 3, the configuration of the power supply management system 100 will be described. The power supply management system 100 manages the operation of a plurality of power supply devices 1. FIG. 2 shows a situation where the power supply management system 100 selects one power supply device 1 from a plurality of power supply devices 1, mounts the aircraft 50 to be moved (hereinafter referred to as the target aircraft 50), and moves it.

[0023] In FIG. 2, the selected power supply device 1 mounts the target aircraft 50 in the storage area Ar1, and moves it from the storage area Ar1 to the departure / arrival area Ar3 via the parking area Ar2. The storage area Ar1, the parking area Ar2, and the departure / arrival area Ar3 correspond to the predetermined locations and moving locations of the present disclosure. The storage area Ar1 corresponds to the first location of the present disclosure, and the departure / arrival area Ar3 corresponds to the second location of the present disclosure.

[0024] The power supply management system 100 communicates with the aircraft management system 210, the multiple power supply devices 1, and the aircraft 50 via the communication network 200. The aircraft management system 210 is a computer system equipped with a processor, memory, communication unit, etc., and records the movement plans of multiple aircraft.

[0025] The power supply management system 100 accesses the aircraft DB 211 of the aircraft management system 210 to obtain movement plan information MVP showing the movement plan of the target aircraft 50. The power supply management system 100 also receives first battery status information BC1, which shows the status of the first battery 11, transmitted from each power supply device 1, and second battery status information BC2, which shows the status of the second battery 52, transmitted from the aircraft 50.

[0026] The power supply management system 100 determines which power supply device 1 to select based on the aircraft 50's movement plan recognized from the movement plan information MVP, the state of the first battery 11 recognized from the first battery state information BC1, and the state of the second battery 52 recognized from the second battery state information BC2.

[0027] Referring to Figure 3, the power supply management system 100 is a computer system equipped with a processor 110, memory 120, communication unit 130, etc. The communication unit 130 communicates with the aircraft management system 210, the aircraft 50, and the multiple power supply devices 1 via the communication network 200.

[0028] Memory 120 stores aircraft data 122, which records information about the aircraft 50 such as the control program 121 of the power supply management system 100, the movement plan information MVP, and the second battery status information BC2, and power supply device data 123, which records information about the power supply device 1 such as the first battery status information BC1.

[0029] The processor 110 functions as a first battery state recognition unit 111, a movement plan recognition unit 112, a second battery state recognition unit 113, and a power supply device selection unit 114 by reading and executing the control program 121.

[0030] The first battery state recognition unit 111 receives the first battery state information BC1 transmitted from the power supply device 1 via the communication unit 130 and individually recognizes the state of the first battery 11 of each power supply device 1. The first battery state recognition unit 111 records the first battery state information BC1 in the power supply device data 123.

[0031] The movement plan recognition unit 112 accesses the aircraft DB 211 of the aircraft management system 210 to obtain the movement plan information MVP of the aircraft 50 and recognizes the movement plan of the aircraft 50 from the movement plan information MVP. The movement plan recognition unit 112 records the movement plan information MVP in the aircraft data 122. The second battery status recognition unit 113 receives the second battery status information BC2 transmitted from the aircraft 50 via the communication unit 130 and recognizes the status of the aircraft 50's second battery 52. ​​The second battery status recognition unit 113 records the second battery status information BC2 in the aircraft data 122.

[0032] The power supply device selection unit 114 selects a power supply device 1 from among multiple power supply devices 1 that meets the following conditions. Condition 1: The aircraft 50 can be supplied with a second power equivalent to energy A, which is the amount of energy required to charge the second battery 52 to a level that covers the amount of energy consumed when the aircraft 50 performs the flight according to the travel plan. "The amount of energy consumed when the aircraft 50 performs the flight according to the travel plan" is, for example, the amount of energy required to perform the travel plan from the departure point to the destination, if the aircraft flies using only the power of the battery 52. Second condition: The vehicle can be supplied with a first power of energy B, which is the amount of energy required to travel from hangar area Ar1 to takeoff and landing area Ar3 with the aircraft 50 loaded on it. "The amount of energy required to travel from hangar area Ar1 to takeoff and landing area Ar3" is, for example, the amount of energy calculated from the distance traveled from Ar1 to Ar3 and the energy consumption of the power supply device 1, taking into account the weight of the loaded aircraft 50 (travel distance per predetermined power).

[0033] [3. Selection process of power supply devices by the power supply management system] Following the flowchart shown in Figure 4, the procedure for selecting the power supply device 1, as performed by the power supply management system 100 in the situation shown in Figure 2, will be explained.

[0034] In step S10 of Figure 4, the power supply device selection unit 114 proceeds to step S11 when it receives movement request information from the aircraft management system 210 requesting the movement of the target aircraft 50. In step S11, the second battery state recognition unit 113 receives second battery state information BC2 from the target aircraft 50 and recognizes the state (amount of charge, temperature, etc.) of the target aircraft 50's second battery 52 from the second battery state information BC2.

[0035] In the following step S12, the movement plan recognition unit 112 accesses the aircraft DB 211 of the aircraft management system 210 to obtain the movement plan information MVP of the target aircraft 50 and recognizes the movement plan of the target aircraft 50 from the movement plan information MVP. In the next step S13, the first battery state recognition unit 111 receives the first battery state information BC1 from a plurality of standby power supply devices 1 and recognizes the state (amount of charge, temperature, etc.) of the first battery 11 of each power supply device 1 from the first battery state information BC1.

[0036] In the next step S14, the power supply device selection unit 114 selects a power supply device 1 that satisfies the first and second conditions based on the movement plan of the target aircraft 50, the state of the second battery 52 of the target aircraft 50, and the state of the first battery 11 of each power supply device 1. Alternatively, the power supply device 1 may be selected if the amount of energy C that can be supplied from the installed first battery 11 is greater than the sum of the energy A in the first condition and the energy B in the second condition (energy C > energy A + energy B), and the first battery 11 has sufficient stored energy.

[0037] In the following step S15, the power supply unit selection unit 114 transmits movement instruction information to the selected power supply unit 1 instructing it to move the target aircraft 50, thereby arranging the movement of the target aircraft 50. As a result, as shown in Figure 2, the selected power supply unit 1 travels from the hangar area Ar1 through the parking area Ar2 to the take-off and landing area Ar3 while supplying power to the target aircraft 50 on which it is parked.

[0038] [4. Control processing of power supply by power supply device] The procedure for the power supply control process performed by the power supply device 1 will be explained according to the flowchart shown in Figure 5.

[0039] In step S20 of Figure 5, when the power supply control unit 24 receives movement instruction information for the target aircraft 50 from the power supply management system 100, it proceeds to step S21. In step S21, the movement plan recognition unit 21 accesses the aircraft DB 211 of the aircraft management system 210 to obtain the movement plan information MVP for the target aircraft 50 and recognizes the movement plan of the target aircraft 50 from the movement plan information MVP.

[0040] In the following step S22, the driving control unit 25 drives automatically to the hangar area Ar1 where the target aircraft 50 is waiting. In the next step S23, when the driving control unit 25 recognizes that the target aircraft 50 has been placed on the pad through communication with the target aircraft 50, it proceeds to step S24 and fixes the target aircraft 50 to the pad 40 with the fixing device 42 (see Figure 1).

[0041] In the next step S25, the power supply control unit 24 connects the power supply arm 41 to the charging port 51 of the target aircraft 50. In the following step S26, the second battery state recognition unit 23 receives the second battery state information BC2 from the aircraft 50 and recognizes the state of the second battery 52 (amount of charge, temperature, etc.) from the second battery state information BC2.

[0042] In the following step S27, the power supply control unit 24 controls the first power supplied to the running unit 16 and the second power supplied to the target aircraft 50, based on the movement plan of the target aircraft 50 and the state of the second battery 52 of the target aircraft 50, and moves the power supply device 1 to the next area (parking area Ar2, takeoff and landing area Ar3 in Figure 2).

[0043] [5. Other Embodiments] Figure 2 shows an example where a power supply device 1 is selected for one target aircraft 50 and the target aircraft 50 is moved. However, even when there are multiple target aircraft 50, the power supply management system 100 similarly selects one power supply device 1 for each target aircraft 50 and moves each target aircraft 50.

[0044] In the above embodiment, the second battery 52 mounted on the aircraft 50 was charged by the power supplied to the aircraft 50 from the power supply device 1. In another embodiment, the second battery 52 may not be charged, but power may be supplied to the aircraft 50 from the power supply device 1 in order to operate the battery temperature control unit 53. In this case, for example, the amount of power D that needs to be supplied to the aircraft 50 from the power supply device 1 is calculated by following the steps (1) to (5) below. (1) Obtain information on the temperature state of the second battery 52. (2) Obtain information on the target temperature (e.g., 25 degrees) of the second battery 52. ​​The target temperature may be set in advance. (3) Obtain information on the outside temperature (actual temperature or predicted temperature, e.g., 0 degrees). (4) From the aircraft 50's travel plan, information is obtained on the amount of time (e.g., 5 hours) during the period from the aircraft 50's scheduled departure time that temperature control of the second battery 52 is required. (5) Based on the information obtained in (1) to (4) above, calculate the amount of electricity D required to control the temperature of the second battery 52 to the target temperature by the scheduled departure time.

The configuration of the power supply device 1 and the power supply management system 100 may be configured by other divisions. Furthermore, the processing of each component may be performed by one hardware unit or by multiple hardware units. Also, the processing of each component shown in Figures 4 and 5 may be performed by one program or by multiple programs.
