In FIG. 2, the non-contact power transmission system 100 includes an air vehicle port 110 and a power transmission device 120, and the power transmission device 120 further includes a power transmission coil 121 and a power transmission module 122. The flying object 200 includes a power receiving device 210 having a power receiving coil 211 and a power receiving module 212, and further includes a propeller, a motor, a battery, and the like.

The aircraft port 110 is arranged above the utility pole 10 and has an area where the aircraft 200 can land. Specifically, the flying object port 110 is attached and fixed to the upper part of the utility pole 10 by using a metal member such as a connecting metal fitting, a bolt, a nut, and a screw wire. Further, in order to attach the port 110 for the flying object to the upper part of the utility pole 10 and stably fix it, other members may be used, and for example, a resin member such as a plastic belt may be used.

The central region of the aircraft port 110 is configured, for example, to be substantially horizontal with no or less obstacles to the landing of the aircraft 200. As a result, the flying object 200 is easy to land, the possibility of falling when landing is reduced, and the flight can be smoothly carried out even when the aircraft departs.

Further, here, the port 110 for the flying object is substantially rectangular, but is not limited to this, as long as it has a shape such as a square, a circular shape, an ellipse, etc., which makes it easy for the flying object 200 to land. It does not matter if it has the shape of.

The power transmission device 120 acquires electric power from the electric wire and transmits the electric power to the air vehicle 200 landing on the air vehicle port 110 in a non-contact manner. Specifically, the power transmission module 122 controls power transmission to the air vehicle 200 by taking in electricity flowing through the low-voltage distribution line in the utility pole 10 as a power source and transmitting high-frequency power to the power transmission coil 121.

The power transmission coil 121 is arranged around the flight body port 110, and transmits power to the flight body 200 landing on the flight body port 110. Specifically, non-contact power transmission is performed by a magnetic field resonance method between the power transmission coil 121 and the power receiving coil 211 arranged on the leg of the flying object 200.

The power transmission module 122 is the lower part of the flight body port 110 and is attached to the utility pole 10, and does not hinder the flight body 200 when it landed on the flight body port 110. In addition, the possibility of contact with the flying object 200 and other objects (for example, birds, dust, waste, etc.) is low, and factors that cause a failure are eliminated.

By landing on the flight body port 110, the flight body 200 supplies power to the battery mounted on the flight body 200. Specifically, the power receiving coil 211 is arranged on the leg of the flying object 200, and as described above, the power in a non-contact manner by the magnetic field resonance method between the power receiving coil 211 and the power transmission coil 121. Transmission is performed, and power reception is controlled by the power receiving module 212.

In this way, by accreting the flying object 200 to the flying object port 110 of the non-contact power transmission system 100 attached to the utility pole 10, power is supplied to the battery mounted on the flying object 200.

The power receiving coil 211 is attached to the lower part of the flying object 200, for example, a leg, in consideration of the positional relationship with the power transmission coil 121. The power receiving module 212 may be attached to any position of the flying object 200, but by attaching the power receiving module 212 to a leg other than the leg to which the power receiving coil 211 is attached, the power receiving module 212 may be attached to the flying object 200. The weight balance can be secured.

Further, the flying object 200 may be landed on the flying object port 110 and fixed at an appropriate position during the period of power supply. For example, when the wind is strong, the flying object 200 is fixed or opened / closed to the flying object port 110 so as not to deviate from an appropriate feeding position such as tilting, falling, or falling from the flying object port 110. A type fence, an opening / closing type lid, or the like may be provided. Further, the air vehicle 200 and the air vehicle port 110 may be fixed by a fixture, may be fitted to a part of the air vehicle port 110 in the structure of the air vehicle 200, or may be temporarily fitted with a magnet or an adhesive. It may be adhered to.

On the other hand, the power receiving coil 211 is attached to, for example, the leg of the flying object 200, but the power receiving coil 211 is also a solenoid type or a spiral type (circular type) like the power transmission coil 121, and the flight. A circular or oval coil may be applied depending on the shape of the mounting portion (leg portion) of the body 200. Further, the power receiving coil 211 is arranged so as to be substantially parallel to the landing surface of the flying object 200 at the flying object port 110.

The types and arrangements of the coils applied to the power transmission coil 121 and the power receiving coil 211 are not limited to this, and other modes may be used as long as power transmission is efficiently performed. not.

[Functions of contactless power supply system]
FIG. 3 is a functional block diagram showing the functions of each part in the non-contact power feeding system 300 according to the embodiment of the present invention. In FIG. 3, the power transmission device 120 in the non-contact power transmission system 100 on the power transmission side and the power reception device 210 in the air vehicle 200 on the power reception side supply power to the battery 220 mounted on the air vehicle 200. It can be regarded as a non-contact power transmission system 300.

The power transmission device 120 includes a power transmission coil 121 and a power transmission module 122. Further, the power transmission module 122 includes a high frequency power supply unit 123, a control unit 124, and a storage unit 125.

The high frequency power supply unit 123 includes, for example, a DC power supply device, an inverter circuit, and the like. The DC power supply device generates a DC voltage by rectifying the AC voltage taken in as a power source from the low voltage distribution line in the electric pole 10 by a rectifier circuit and smoothing it by a smoothing capacitor. Then, the DC power supply device converts the generated DC voltage into a DC voltage of a predetermined level (target voltage) by the DC-DC converter circuit and outputs it to the inverter circuit. The inverter circuit is a circuit that converts DC power into high frequency power, and outputs the high frequency voltage obtained by the conversion to the power transmission coil 121.

The control unit 124 includes, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The control unit 124 stores a control program or the like for controlling the operation of each unit, and by executing the control program and further executing various programs stored in the storage unit 125, the operation of each unit is executed. To control. For example, the control unit 124 determines the start and end of power transmission as the power transmission device 120, and controls the power transmission process and the like.

The storage unit 125 is, for example, a storage device using a SRAM (Static Random Access Memory), a flash memory, or the like, and the storage unit 125 is used to execute various computer programs executed by a CPU and various computer programs. The data used is stored.

The power transmission coil 121 transmits the high frequency power supplied from the high frequency power supply unit 123 to the flying object 200 having the battery 220 to be supplied. Specifically, a resonance circuit is formed by the transmission coil 121 and the resonance capacitor (not shown) so that the resonance frequency of the resonance circuit matches the frequency of the high frequency power supplied from the high frequency power supply unit 123. , Transmission coil 121 and resonant capacitor are designed.

Next, the power receiving device 210 in the flying object 200 on the power receiving side will be described. The power receiving device 210 includes a power receiving coil 211 and a power receiving module 212.

The power receiving coil 211 magnetically couples with the power transmission coil 121 on the power transmission side to receive high frequency power transmitted from the power transmission device 120 in a non-contact manner. Specifically, a resonance circuit is formed by the power receiving coil 211 and a resonance capacitor (not shown), and the power receiving coil 211 and the resonance occur so that the resonance frequency of the resonance circuit matches the resonance frequency on the transmission side. The capacitor is designed.

The power receiving module 212 controls to supply the high frequency power received through the power receiving coil 211 to the battery 220. Specifically, the power receiving module 212 includes a rectifying and smoothing circuit that converts the received high-frequency power into DC power, and supplies the DC power converted by the rectifying and smoothing circuit to the battery 220.

The battery 220 is a secondary battery capable of charging and discharging, for example, a lithium ion battery, a lithium polymer battery, or the like. The battery 220 is not limited to the lithium ion battery or the lithium polymer battery, and another rechargeable / dischargeable secondary battery may be used.

In this way, the battery 220 is supplied with power, and the flying object 200 can rotate the propeller and fly by driving the motor by, for example, a motor control unit.

[Operation of contactless power supply system]
FIG. 4 is a flowchart showing a feeding method 400 for feeding the flying object 200 executed by the non-contact feeding system 300 according to the embodiment of the present invention. In FIG. 4, the power feeding method 400 includes steps S410 to S440, and each step is executed by being controlled by a processor such as a CPU included in the contactless power transmission system 100 and the air vehicle 200.

In step S410, the non-contact power transmission system 100 determines whether or not the air vehicle 200 has landed on the air vehicle port 110. When it is detected that the flight object 200 has landed on the flight object port 110, the process proceeds to the process of step S420 (Yes in step S410). On the other hand, if it is not detected that the flying object 200 has landed on the flying object port 110, it is continuously monitored whether or not the flying object 200 has landed on the flying object port 110 (No in step S410). ..

Specifically, a sensor may be provided in the vicinity of the flight body port 110, and the accretion of the flight body 200 may be detected by the sensor. The sensor is, for example, an optical non-contact sensor using visible light or infrared light, a contact sensor, a magnetic sensor, a weight sensor, a pressure sensor, a camera, or the like, indicating that the flying object 200 has landed on the flying object port 110. Anything that can be detected will do.

In step S420, the non-contact power transmission system 100 starts the power transmission process. Specifically, the power transmission device 120 starts power transmission to the power receiving coil 211 in the power receiving device 210 via the power transmission coil 121.

In step S430, the non-contact power transmission system 100 determines whether or not a predetermined amount of power transmission has been reached. When the predetermined amount of power transmission is reached, the process proceeds to the process of step S440 (Yes in step S430). On the other hand, if the predetermined amount of power transmission has not been reached, power is continuously transmitted until the predetermined amount is reached (No in step S430).

Further, in determining whether the non-contact power transmission system 100 stops power transmission (Yes in step S430) or continues (No in step S430), the battery voltage of the battery 220 to be supplied is monitored, and the battery voltage is predetermined. You may judge whether or not the value has been reached. When the battery voltage reaches a predetermined value, the process proceeds to step S440 (Yes in step S430), and when the battery voltage does not reach the predetermined value, power transmission may be continued (No in step S430).

Whether or not a predetermined amount of power transmission has been reached is determined by, for example, the contactless power transmission system 100 and the air vehicle 200 each having a communication unit, and the battery 220 mounted on the air vehicle 200 by each communication unit performing wireless communication. The information regarding the power supply to the power transmission device 120 may be determined by notifying the power transmission device 120 from the aircraft body 200.

Specifically, when the battery 220 mounted on the flying object 200 is monitored and the battery 220 is charged to a predetermined amount, for example, a wireless communication method such as WiFi (registered trademark) or Bluetooth (registered trademark). Is used to notify the power transmission device 120 from the air vehicle 200. In response to this, the contactless power transmission system 100 may determine that a predetermined amount of power transmission has been reached.

When monitoring the battery voltage of the battery 220, the power receiving module 212 monitors the battery voltage of the battery 220, and when the battery voltage reaches a predetermined value, the power transmission path between the rectifying smoothing circuit and the battery 220 is cut off (). OPEN). When the power transmission path is cut off, the reflected wave power detected by the power transmission module 122 increases, so that the battery voltage of the battery 220 reaches a predetermined value and the charge to the battery 220 reaches a predetermined amount. You can judge. As a result, the non-contact power transmission system 100 may stop power transmission. In this method, the power transmission module 122 is provided with a function of detecting forward wave power and reflected wave power, so that the non-contact power transmission system 100 can be used even if the non-contact power transmission system 100 and the air vehicle 200 are not provided with communication units, respectively. , It is possible to determine whether or not to stop power transmission.

Further, without monitoring the battery 220 mounted on the flying object 200, for example, the charge amount of the battery 220 is estimated based on the power transmission time after the non-contact power transmission system 100 starts the power transmission process in step S420. However, when the estimated charge amount of the battery 220 reaches a predetermined amount, it may be determined that the predetermined amount of power transmission has been reached.

Here, the predetermined amount may be the maximum capacity of the battery 220 mounted on the flying object 200, may be 30%, 50%, 80%, etc. of the maximum capacity, and may be preset. It may be a predetermined amount or the like. Further, considering that the port 110 for the aircraft is attached to the utility pole 10 installed in the city, the battery 220 does not need to be supplied with a large capacity, and the utility pole 10 adjacent to or to be landed next is not required. It suffices if power is supplied to (port 110 for the flying object) to the extent that the flying object 200 can fly.

In step S440, the non-contact power transmission system 100 stops the power transmission process.

After that, the flying object 200 exits from the flying object port 110. For example, the flying object 200 is discharged from the flying object port 110 after the power feeding process to the battery 220 is stopped. Regarding the fact that the power supply processing to the battery 220 has been stopped, the air vehicle 200 and the contactless power transmission system 100 are each provided with a communication unit, and each communication unit performs wireless communication, so that the contactless power transmission system 100 stops the power transmission process. The non-contact power transmission system 100 may notify the air vehicle 200 of the information indicating that the power transmission has been performed.

As described above, according to the non-contact power transmission system 100, the non-contact power transmission system 300, and the power supply method 400 according to the embodiment of the present invention, the air vehicle port 110 is arranged on the utility pole 10 and the air vehicle port is provided. Since the power transmission coil 121 is provided around the 110, the power transmission device 120 can acquire electric power from the electric wire and transmit power to the air vehicle 200 landing on the air vehicle port 110 in a non-contact manner. Even when the flying object 200 is equipped with a small and lightweight battery 220 and the entire flying object 200 is made smaller and lighter, the flying object 200 can be landed on the flying object port 110 arranged on the electric pole 10. For example, a magnetic field resonance method is used to supply power to the battery 220 in a non-contact manner. That is, since the battery 220 can be appropriately supplied with power while avoiding the battery 220 being out of charge during flight, it is possible to realize a compact and lightweight flying object 200 capable of long-time flight and long-distance flight.

In the present embodiment, the air vehicle port 110 is configured in the shape of a mesh plate, but the present invention is not limited to this, and is affected by wind and rain when installed outdoors. If the configuration is difficult, for example, a plate shape having a plurality of ventilation holes may be used. Vents may be arranged, for example, linear, corrugated, square, triangular, circular, oval, etc., even if the air vehicle port 110 is blown by the wind or struck by the rain. Other shapes may be used as long as the force can be released and the air vehicle 200 can stably land on the air vehicle port 110.

Further, in the present embodiment, the flight body port 110 is configured to be arranged on the upper part of the utility pole 10, but the present invention is not limited to this, and for example, a position where electricity can be easily taken in near a low voltage distribution line. Alternatively, it may be arranged at a position of the utility pole 10 that is easy to fix.

Further, the flight body port 110 is preferably arranged at a position of the utility pole 10 where the flight object 200 can easily land, and is preferably attached to the uppermost stage of the utility pole 10, for example. Further, if the flight body port 110 is arranged at a position of the utility pole 10 away from the ground, it is possible to reduce the influence on the electronic devices and the human body on the ground.

In the present embodiment, the utility pole 10 installed in the city is taken as an example of the support equipment for installing the non-contact power transmission system 100, but the support equipment is not limited to this, for example, in the suburbs. It may be a utility pole installed in a mountain or a mountain, or it may be a power transmission tower or a utility pole as long as it can acquire electric power as a power source.

As a result, the state of the utility pole 10 installed in the city and the electric wire relayed to the utility pole 10 can be confirmed. For example, the deterioration state of the utility pole or the electric wire can be checked, or a failure such as a power outage occurs. If so, it is possible to investigate the cause, such as identifying the location of the disconnection. Furthermore, it is possible to monitor a predetermined city, area, building, facility, etc., and it can be used for security and crime prevention.

Further, the aircraft 200 may be allowed to transport the luggage. In this case, the size and weight of the cargo transported by the flying object 200 affect the consumption of the battery 220. If the position of the utility pole 10 installed in the city can be grasped, it is possible to preset a flight path indicating which utility pole 200 will fly to the destination while landing on the utility pole port 110 of the utility pole 10. can.

If the flight path is set in advance, the landed aircraft port 110 will be determined according to the flight distance to the next landing aircraft port 110, the size and weight of the luggage to be transported, and the capacity and performance of the mounted battery 220. It is possible to grasp the power to be supplied in. That is, the flying object 200 can transport the luggage to the destination while appropriately accreting to the flying object port 110 and supplying power to the battery 220 before the battery 220 is out of charge.

In the example shown in FIG. 5, the flight body 200 landed on the flight body port 110 attached to the utility pole 10, supplied power to the battery 220, and then in turn attached to the adjacent utility pole 10. Although it is assumed that the aircraft will fly to the body port 110, the flight body port 110 provided on the other utility pole 10 to be landed next is not limited to this. For example, depending on the capacity and performance of the battery 220 mounted on the flight object 200, the consumption status at that time, and the like, a route within a predetermined range from the flight object port 110 or a preset route according to the destination. It may be determined in order based on.

In this way, it is sufficient that the flight body 200 grasps the flight body port 110 to be landed next, and the power supply necessary for the flight to the flight body port 110 is performed, and the excessive power supply and the accompanying flight body are used. It is possible to avoid long-term stagnation in the port 110. That is, it is possible to quickly and appropriately supply necessary and sufficient power while avoiding running out of charge.

If the flight body port 110 capable of supplying power to the battery 220 mounted on the flight body 200 is installed, for example, every several hundred meters, it is possible to supply power frequently and finely. Therefore, it is not necessary to mount a large-capacity large battery on the flying object 200, and the flying object 200 can be made smaller and lighter, and as a result, the flight efficiency can be improved.
