The power receiving device 140 is a device that receives power supplied from the charging station 200 by using an electromagnetic field resonance phenomenon. The power receiving device 140 supplies the power to the power source 110. The power receiving device 140 is in a state in which the flying toy 100 has landed on the charging station 200 (hereinafter referred to as “landing state”) or in a state in which the flying toy 100 has stopped in the air on the charging station 200 (hereinafter referred to as “ The power can be received from the charging station 200. Such a power receiving device 140 includes, for example, a power receiving coil 141, a capacitor 142, a rectifier circuit 143, and a voltage stabilization circuit 144, and is appropriately disposed inside the flying toy 100.

  The power receiving coil 141 is a coil that resonates with a magnetic field generated from a conductive coil and generates AC power. The power receiving coil 141 has a fixed inductance value. The power receiving coil 141 is formed of, for example, a litz wire to reduce the influence of the skin effect and is an alpha winding coil. For example, the power receiving coil 141 is connected in parallel to the capacitor 142 via a conductive wire, and is connected in parallel to the power source 110 via a rectifier circuit 143. When the receiving coil 141 resonates with the magnetic field, a current flows through the litz wire.

<< Route recognition sensor 150 >>
The route recognition sensor 150 is, for example, an infrared sensor having a function of receiving a signal indicating a flight route (hereinafter referred to as “route signal”) output from the flight rail 300. The route recognition sensor 150 outputs a route signal to the flying object controller 170 described later.

<< Distance sensor 160 >>
The distance sensor 160 has a function of measuring the distance between the flying toy and the ground. The distance sensor 160 transmits a signal indicating the distance to the ground (hereinafter referred to as “altitude signal”) to the flying object control device. Thereby, the flying toy can fly at a constant altitude from the ground.

<< Aircraft Control Device 170 >>
The flying object control device 170 is a device that controls the flying toy 100 to fly along the flight path and to charge the flying toy 100 by either landing or hovering at the charging station 200. As shown in FIG. 5, the flying object control device 170 having such a function includes an arithmetic processing unit 171, a storage unit 172, an input unit 173, an output unit 174, and a memory 175. ing.

  The arithmetic processing unit 171 is configured by, for example, a CPU or MPU. The arithmetic processing unit 171 implements various functions by reading a program stored in the memory 175. The arithmetic processing unit 171 includes a first recognition unit 171a, a result reception unit 171b, a first determination unit 171c, a flight control unit 171d, and a charge management unit 171e. The arithmetic processing unit 171 reads various information from the storage unit 172, and executes the processing of each component described above. Hereinafter, processing of each component will be described in detail.

  The first recognition unit 171a has a function of recognizing the charging station 200. For example, the first recognizing unit 171a receives an infrared signal (hereinafter referred to as “notification signal”) from the charging station 200 via the input unit 173, and receives the signal based on the notification signal via the output unit 174. A signal (hereinafter referred to as “response signal”) informing this is transmitted to the charging station 200. Thereby, the state which can communicate between the flying body toy 100 and the charging station 200 is ensured. The first recognition unit 171a acquires a route signal indicating the flight route from the route recognition sensor 150 and outputs the route signal to the flight control unit 171d. Thereby, the flying body toy 100 can fly along a flight route.

  When the result receiving unit 171b (receiving device) and the charging station 200 can communicate with each other, the charging station 200 determines whether the charging station 200 is charged in a landing state or in a hovering state. It has a function of receiving a signal (hereinafter referred to as “recognition signal”). The result receiving unit 171b transmits the recognition signal to the first determination unit 171c described later.

  Based on the recognition signal, the first determination unit 171c determines whether charging in the landing state (hereinafter referred to as “landing charging”) or charging in the hovering state (hereinafter referred to as “hovering charging”). It has the function to do. Thereby, the charge corresponding to the setting of the power transmission device 220 of the charging station 200 can be performed.

  The flight control unit 171d has a function of controlling the rotor 120 and the motor 130 based on the determination result in the first determination unit 171c. Thereby, it can charge by landing on the charging station 200 or hovering on the charging station 200. Further, the flight control unit 171d controls the rotor 120 and the motor 130 so that the flying toy 100 flies on the flight rail 300 based on the path signal acquired from the first recognition unit 171a. In addition, the flying object control unit 171d controls the rotary wing 120 and the motor 130 so that the flying object toy 100 maintains a certain distance from the flying rail 300 based on the altitude signal acquired from the distance sensor 160.

  The charge management unit 171e monitors the power capacity of the flying toy 100 after starting charging and confirms that the power capacity of the power source 110 has been satisfied. It has a function of outputting a signal (hereinafter referred to as “flight signal”) to the flight control unit 171e. The charge management unit 171e confirms that the power capacity of the power source 110 is satisfied, for example, by acquiring a signal indicating completion of charging from the power source 100. Thereby, since the charging is completed at the same time as the charging of the power source 110 is completed, the charging can be performed in the shortest charging time.

  In addition, the charge management unit 171e has a function of determining a charging time based on a charging time for charging in a predetermined hovering state and a charging time for charging in a landing state as a function different from the above. Also good. Specifically, for example, the charge management unit 171e acquires time information related to each charging time from the storage unit 172 in which each charging time in landing charging and hovering charging is stored in advance. The charge management unit 171e outputs a flight signal to the flight control unit 171d after a predetermined charging time corresponding to the time information has elapsed. Thereby, since it only has to charge in a predetermined charging time, the control for charging the flying toy 100 can be simplified.

  In addition, as a function different from the above, for example, when the flying toy 100 and the charging station 200 are communicably connected, the charging management unit 171e confirms the power capacity of the flying toy 100, and the power capacity May have a function of determining the charging time. In this case, charging time information indicating the charging time corresponding to the power capacity is stored in the storage unit 172, and the charging management unit 171e acquires the charging time information from the storage unit 172. The charge management unit 171e outputs a flight signal to the flight control unit 171d after a predetermined charging time corresponding to the charging time information has elapsed. Accordingly, since the flying toy 100 can be charged with an appropriate charging time rather than charging with a predetermined charging time in each of the landing charging and the hovering charging, the charging time can be shortened.

  The storage unit 172 is a device that stores programs and various types of information. The storage unit 172 is configured by, for example, a ROM, a RAM, or a flash memory. The input unit 173 is an interface through which various signals are input from the charging station 200 using infrared communication, and various signals are input from the path recognition sensor 150 in a predetermined signal format. The output unit 174 is an interface that outputs various signals to the charging station 200 using infrared communication. The memory 175 is a device that stores a program to be processed by the arithmetic processing unit 171. The memory 175 is composed of, for example, a hard disk drive, SSD, or optical storage device.

FIG. 6 is a configuration diagram illustrating an example of the charging station 200 according to the present embodiment. FIG. 7 is a hardware configuration diagram illustrating an example of the charging station 200 of the flying toy 100 according to the present embodiment.

  The charging station 200 is a device for supplying power to the flying toy 100 in a non-contact manner. Adjacent charging stations 200 are connected by a flight rail 300. As shown in FIG. 6, such a charging station 200 includes a changeover switch 210, a power transmission device 220, and a charge control device 230.

<< Changeover switch 210 >>
The changeover switch 210 is a manual switch that selectively switches between a first power transmission path 225 and a second power transmission path 226 described later. Further, the changeover switch 210 is provided on the exposed surface of the charging station 200 so that the operator can easily operate it. As shown in FIG. 2, the changeover switch is interlocked with the first auxiliary switch 240 and the second auxiliary switch 250. Specifically, as shown in FIG. 2, when the changeover switch 210 is set to “A”, the first auxiliary switch 240 is connected to the eleventh contact 241 so as to form the first power transmission path 225. The second auxiliary switch 250 is connected to the 21st contact 251. On the other hand, when the changeover switch 210 is set to “B”, the first auxiliary switch 240 is connected to the twelfth contact 242 and the second auxiliary switch 250 is connected to the twenty-second contact 252 so as to form the second power transmission path 226. Connected to.

  The changeover switch 210 outputs a contact signal indicating whether the first power transmission path 225 is formed or the second power transmission path 226 is formed to the charging control device 230. Thereby, the charging control device 230 can recognize whether the charging station 200 is set to the charging mode by “landing” or the charging mode by “hovering”.

<< Power Transmission Device 220 >>
The power transmission device 220 is a device that performs non-contact power feeding to the power receiving device 140 using the resonance phenomenon of the electromagnetic field. Here, the distance between the power transmission device 220 and the power receiving device 140 in a state where the flying toy 100 is landing on the charging station 200, and the power transmission in the state where the flying toy 100 is hovering on the charging station 200. The distance between the device 220 and the power receiving device 140 is different. Therefore, the power transmission device 220 is configured to be able to change the electrical characteristics in accordance with each state. Such a power transmission device 220 includes a DC power source 221, a high frequency power source 223, a power transmission coil 224, a first power transmission path 225, and a second power transmission path 226, and is appropriately disposed inside the charging station 200. Yes.

  The DC power source 221 is, for example, a dry battery that supplies DC power. The power capacity of the DC power source 221 is predetermined in the design of the flying toy system 10. The second power transmission path 226 is provided with an auxiliary DC power supply 222 connected in series with the DC power supply 221. Thus, a power source having an appropriate power capacity is configured according to each of the landing state and the hovering state.

  The high frequency power supply 223 is, for example, a power supply that has an inverter function and converts the direct current of the direct current power supply 221 into an alternating current of a desired frequency of the power transmission device 220. The high frequency power supply 223 is configured to include, for example, a half bridge output circuit.

  The power transmission coil 224 is a coil for resonating the magnetic field generated from the conductive coil by the alternating current supplied from the high-frequency power source 223 with the power receiving coil 141 and transmitting the AC power to the power receiving coil 141. Since the structure of the power transmission coil 224 is the same as that of the power reception coil 141, the description thereof is omitted. The power transmission coil 224 is connected in series with a first capacitor 225a or a second capacitor 226a described later via a conductive wire. The power transmission coil 224 is one element for determining the resonance frequency in the power transmission device 220.

  The first power transmission path 225 is a power transmission path that is selected when power is transmitted from the power transmission apparatus 220 to the power reception apparatus 140 when the flying toy 100 is in the landing state. A first capacitor 225 a is connected to the first power transmission path 225. The first capacitor 225 a has a capacitance that is equal to the power reception resonance frequency of the power reception device 140 and is used as the power transmission resonance frequency of the power transmission device 220 in the landing state. The capacitance of the first capacitor 225a is set in advance. As shown in FIG. 3, the first power transmission path 225 is in a state where the first auxiliary switch 240 is connected to the eleventh contact 241 and the second auxiliary switch 250 is connected to the twelfth contact 242. And formed.

  The second power transmission path 226 is a power transmission path selected when power is supplied from the power transmission apparatus 220 to the power reception apparatus 140 when the flying toy 100 is in the hovering state. A second capacitor 226 a is connected to the second power transmission path 226. Second capacitor 226 a has a capacitance equal to the power reception resonance frequency of power reception device 140, which is the power transmission resonance frequency of power transmission device 220 in the hovering state. The capacitance of the second capacitor 226a is set in advance. Further, an auxiliary DC power supply 222 is provided in the second power transmission path 226 so as to be connected in series with the DC power supply 221. Since the distance between the flying toy 100 and the charging station 200 is long in the hovering state, it is necessary to increase the power of the DC power supply 221, so the auxiliary DC power supply 222 is provided. As shown in FIG. 3, the second power transmission path 226 is in a state in which the first auxiliary switch 240 is connected to the twelfth contact 242 and the second auxiliary switch 250 is connected to the twenty-second contact 252. In, formed.

  In this way, by providing a configuration capable of switching between the first power transmission path 225 and the second power transmission path 226, the power transmission resonance frequency is set to be equal to the power reception resonance frequency in either the landing state or the hovering state. Since it can be set, power transmission efficiency can be maintained high.

<< Charging Control Device 230 >>
The charging control device 230 is a device that starts the energization of the power transmission coil 224 by controlling the third auxiliary switch 260 and further informs the flying toy 100 whether to charge in the landing state or the hovering state. As shown in FIG. 7, the charging control device 230 having such a function includes an arithmetic processing unit 231, a storage unit 232, an input unit 233, an output unit 234, and a memory 235. Yes.

  The arithmetic processing unit 231 is configured by, for example, a CPU or MPU. The arithmetic processing unit 231 implements various functions by reading a program stored in the memory 235.

The arithmetic processing unit 231 reads various information from the storage unit 172, and executes the processing of each component described above. Hereinafter, processing of each component will be described in detail.

  The second recognition unit 231a has a function of recognizing whether it is landing charging or hovering charging based on the contact signal of the changeover switch 210. The second recognition unit 231a generates a recognition signal indicating the recognition result. The second recognizing unit 231 a outputs a notification signal for synchronizing with the flying toy 100 to the flying toy 100. Thereby, the charging station 200 and the flying object toy 100 can be connected so that communication is possible.

  When the result transmission unit 231b (transmission device) becomes communicable with the flying toy 100, the result transmission unit 231b receives a recognition signal indicating the setting state of the charging station 200 as to whether charging is performed in the landing state or charging in the hovering state. A function of transmitting to the flying toy 100 is provided.

  When the switch control unit 231c outputs the recognition signal to the flying toy 100, the third auxiliary switch 260 is closed, and when a predetermined time has elapsed after the flying toy 100 starts charging, It has a function of opening the third auxiliary switch 260. That is, the charging station 200 does not energize the power transmission coil 224 until the flying toy 100 can be powered, and further stops energizing the power transmission coil 224 after the flying toy 100 has been powered. As a result, extra power loss during standby can be reduced.

  The second determination unit 231d has a function of determining whether a predetermined time has elapsed since the charging station 200 started charging the flying toy 100. The predetermined time is a charging time for landing charging or a charging time for hovering charging. Thereby, the charging station 200 can be charged appropriately according to the difference in charging time between the landing charging and the hovering charging.

  Since the storage unit 232, the input unit 233, the output unit 234, and the memory 235 have the same hardware configurations as the storage unit 172, the input unit 173, the output unit 174, and the memory 175 in the flying toy 100, the description thereof is omitted. .

  Next, the charge management unit 171e of the flying object control device 170 determines whether or not the charging of the power source 110 has been completed. When it is determined that the predetermined charging time has elapsed, the charge management unit 171e outputs a flight signal to the flight control unit 171d (S18). In addition, as described above, the charge management unit 171e outputs a flight signal by determining whether or not a charging time for landing charging or a predetermined charging time for hovering charging has elapsed since the start of charging. May be.

  The above S11 to S18 are repeated until the power source 110 of the flying toy 100 is cut off (S19).
