In FIG. 1, the sensors 400, 500, and 600 for communicating the objects distributed to constitute the object communication sensor network are represented by black circles.

The output power of the power storage unit (described below) mounted on the unmanned air vehicle 100 is distributed to the sensors 400, 500, and 600 for distributed use using the wireless power feeding devices corresponding to each wireless power transmission system And supplies power to a plurality of sensors 400, 500, and 600 that require very little power. In addition, by using the fixed wireless power supply device 300, power is also supplied to a plurality of sensors 400, 500, and 600 for long distance communication. In the case of the fixed wireless power supply device 300, the unmanned mobile wireless power supply device 100, which is a unmanned aerial vehicle, has its own distinctiveness.

FIG. 2 is a block diagram illustrating an unmanned wireless power supply 100 according to the present invention. The unmanned power supply 100 may be a small unmanned air drone of various sizes and periodically operates to supply wireless power to the sensors 400, 500 and 600 in various manners in the unmanned aerial vehicle. The unmanned wireless power supply 100 includes an electric motor 110 for providing unattended mobile flight power as shown in FIG. 2, and a power supply unit 200 for wirelessly supplying electric power to the sensors 400, 500, A power storage unit 130 for providing power to the electric motor 110 and the power feed unit 120 and a control unit 140 for controlling the respective components of the unmanned wireless power supply 100, ).

The electric motor 110 obtains the rotational force by using the electric power, and moves up and down according to the number of revolutions, advancing or rotating, and raising the output of the electric motor 110.

The power feeder 120 supplies power wirelessly, and the wireless power transmission technology is not limited to a specific technique. The present invention includes four representative examples of magnetic induction, magnetic resonance, RF, and laser systems .

In the magnetic induction method, the transmission of electric power to the magnetic field is realized by induction coupling phenomenon between the power supply coil and the current collecting coil. At this time, in order that the magnetic field in the power feeder 120 can be concentrated on the current collecting coils of the sensors 400, 500, and 600 having the power collecting part, Coil / core must be configured. Even in the case of a sensor in which an integrated device is incorporated, it also includes an appropriate coil / core for power reception as well.

The self-resonance method is based on the magnetic resonance phenomenon between the feeding resonance coil and the collecting resonance coil, and self-resonating the feeding coil and the collecting coil to realize power transmission using the resonance phenomenon. It is necessary to provide a resonance coil having a resonance frequency close to each other in the feeding part and the current collecting part, and the resonance coil at this time has a resonance frequency

Figure 112015096574528-pat00001
The inductance and the capacitance value must satisfy the following equation. Here, in order to adjust the resonance phenomenon, the radio power transmission performance can be optimized by adjusting the resonance frequency between the feeding part and the current collecting part, or by adjusting the distance and position between the feeding resonance coil and the collecting resonance coil, .

In the case of the RF wireless power transmission method, the power is transmitted to the sensor using the high directivity antenna to minimize the free space loss of the radio wave for power transmission. For this purpose, it is preferable to include a directional antenna in the unmanned mobile wireless power supply apparatus 100 and the fixed wireless power supply apparatus 200 having the power feed unit, and the sensors 400, 500, and 600 for the object communication, A non-directional antenna is provided.

The expansion of the power storage unit 130 and the operation of the unmanned wireless power supply apparatus 100 to be described below can be optimized for charging the sensors 400, 500 and 600 for object communication to secure the wireless power transmission capacity . Also, it is preferable that the time for electric power charging of the object communication sensors 400, 500 and 600 becomes longer, and the sensor charging function can be improved by optimizing the performance of the unmanned wireless power supply device 100.

The power storage unit 130 includes a first power storage unit 131 for providing electric power to the electric motor 110 and the power feed unit 120 and supplying electric power to the electric motor 110, And a second power storage unit 132 for storing power in the second power storage unit. The power stored in the first power storage unit 131 and the second power storage unit 132 may be used according to each application and may share the same power. For example, when power stored in the first power storage unit 131 is insufficient to provide power to the electric motor 110, flying becomes difficult. At this time, the power of the second power storage unit 132 is shared .

The control unit 140 controls each component of the unmanned wireless power supply 100 so that the wireless power supplied to the sensors 400, 500, and 600 through the power feed unit 120 is controlled by the visible distance and the non- 500 and 600 in consideration of harmfulness to the human body including the distances of the object communication sensors 400, 500, and 600. Herein, the human body hazard is an electromagnetic wave to the human body. In the present invention, when the human body is harmful due to electromagnetic waves in the direction of the object communication sensor, the direction is switched to supply the wireless power.

3 is a block diagram illustrating a fixed wireless power supply 200 according to the present invention. The fixed wireless power supply 200 includes a power feed unit 220 for wirelessly supplying electric power to the sensors 400, 500 and 600 for objects communication and a power source for switching the direction of electric power supplied from the power feeder 220 A power supply unit 230 for supplying power to the power feeding unit 220 and the power supply unit 210 for turning the power supply and a power supply unit 230 for supplying power to each component of the fixed wireless power supply device 200, And a control unit 240 for controlling the apparatus.

2 may be used to charge a variety of sensors 400, 500, and 600 having a wide range of distribution while moving a limited charging area through a moving operation. However, the unmanned wireless power supply 100 shown in FIG. In the case of the wireless power supply 200, since it can not be moved directly, in order to have a wide charging area, the direction of the charging area for each wireless power transmission technique must be adjustable. For this purpose, various mechanical and electrical power for controlling the direction is required, and a part of the power source of the power source 230 is used as the power source.

The power feeding unit 220 is configured to supply power wirelessly, and the wireless power transmission technique is not limited to a specific technique. In the present invention, four typical examples include magnetic induction, magnetic resonance, RF, 2 in the second embodiment.

The redirection power providing unit 210 provides a direction adjusting power to have a wide charging area.

The power supply unit 230 includes a first power supply unit 231 for providing power to the direction switching power supply unit 210 and a power feed unit 220 for supplying power to the power supply unit 220, And a second power supply unit 232 for supplying power to the second power supply unit. The power of the first power source unit 231 and the power source of the second power source unit 232 can be used according to the application and can share the same power. For example, when the first power source unit 231 is insufficient in power and can not supply power to the direction switching power supply unit 210, it is difficult to change the direction of the power, so that the power of the second power source unit 232 is shared.

The control unit 240 controls each component of the fixed wireless power supply 200 and considers the path change elements of the wireless power supplied to the sensors for communication for objects communication 400, 500 and 600 through the feeder 220 And controls the wireless power to be transmitted in the direction in which the objects communication sensors 400, 500, and 600 are located. Here, the path changing element is an element in which electromagnetic waves are present on the human body and electromagnetic interference may occur in the electromagnetic period.

The current collectors 410, 510, and 610 are current collecting structures corresponding to the radio power transmission technology, like the power feeders 120 and 220 described with reference to FIGS. 2 and 3, ), And in the case of RF power transmission, the sensor should have a non-directional antenna (or rectenna) because it is placed almost randomly. The laser system has a beam receiver. The power received from the current collectors 410, 510, and 610 is stored in the batteries 420, 520, and 620. Sensor operation for object communication is performed by the power sources stored in the batteries 420, 520, and 620, Information is transmitted through the supplies 430, 530, and 630 and driven.

The objects communication sensors 400, 500, and 600 include a portable device, a home appliance, various information devices, video devices such as CCTV, and object communication sensors, which are objects to be wirelessly charged. Power is required. They have irregularly discrete distributions in space and environment and can exist in various environments such as indoor and outdoor buildings. However, they are ineffective when wired network for communication and power supply is wired. Since the installation position is limited when the power and communication lines are connected by wire, and various power / communication lines accompanying it are exponentially increased, In addition to the case where the sensors 400, 500, 600 are fixed in one place, they may be mounted on a moving object or have direct mobility.

The present invention includes scenarios for all of these cases, and also includes scenarios in which a plurality of power feeders and current collectors are configured.

In the wireless power transmission system, all of the electric power is transmitted through the space using electromagnetic waves, so that human health problems may occur. This is a avoidance scenario for overcoming the problem.
