Hereinafter, with reference to the accompanying drawings, a preferred embodiment of a power delivery system using a laser according to the present invention as described above (hereinafter referred to as a "power delivery system") will be described in more detail.

1 is a schematic diagram of a power delivery system according to an embodiment of the present invention.

Referring to FIG. 1, a power delivery system according to an embodiment of the present invention includes an operating object 101, a laser device 102, a reflector 103, and the like.

The actuating object 101 is electrically operated, and is mainly used at a fixed place or fixedly installed. And it is preferable that the power required for operation, such as a door locking device or a speaker is not very large. As shown in FIG. 2, the operation target object 101 includes a photovoltaic cell 21, an actuator 24, a detector 22, a transmitter 23, a controller 20, and the like.

The photovoltaic cell unit 21 receives the laser beam emitted from the laser device 102, converts it into electrical energy, and stores electricity.

The operation unit 24 operates with electrical energy stored in the photovoltaic unit 21. For example, in the case of a door locking device, the door is locked or unlocked, and in the case of a speaker, sound is output.

The detector 22 detects a storage amount of the photovoltaic unit 21.

The transmitter 23 generates an operation signal necessary for the operation of the laser device 102 and wirelessly transmits the generated operation signal.

The controller 20 controls the transmitter 24 to operate when the amount of power storage of the photovoltaic cell 21 sensed by the detector 22 is equal to or less than a predetermined value.

That is, the operation target object 101 operates by using the electric energy stored in the photovoltaic cell unit 21, and generates and sends an operation signal when the amount of power storage of the photovoltaic cell unit 21 is lower than or equal to a predetermined value.

On the other hand, the laser device 102 is fixedly spaced apart from the operation object 101 by a predetermined distance, and emits a laser. The laser device 102 includes a laser emitting unit 31, a receiving unit 32, a time checking unit 33, a control unit 30 and the like.

The laser emitting unit 31 is provided for firing a laser having a large energy and a strong focusing force.

The receiver 32 receives an operation signal wirelessly transmitted from the transmitter 24 of the operation object 101.

The time checking part 33 is provided to check the time according to the operation of the laser emitting part 31.

When the operation signal is received through the receiver 32, the controller 30 operates the laser emitter 31, and then the time checking unit 33 checks the operation time of the laser emitter 31. When the checked time reaches a predetermined time, the operation of the laser emitting unit 31 is stopped.

That is, the laser device 102, when the operation signal is received from the operation object 101, after firing the laser, it is to stop the laser firing when a certain time.

In addition, the reflector 103 serves to pass the laser beam emitted from the laser device 102 to the working object 101, more precisely to the photovoltaic cell 21 of the working object 101 accurately. . That is, when power transmission through the laser is impossible or difficult due to a straight line distance between the operating object 101 and the laser device 102, the reflector 103 is used to solve such a point, and may not necessarily need to be configured. In some cases, a plurality may be provided.

The operation of the power delivery system configured as described above will be described.

In the foregoing, the operating object 101 and the laser device 102 are installed at a predetermined distance apart from each other, and the reflector 103 is installed between the operating object 101 and the laser device 102.

When the operating unit 22 of the operating object 101 uses electric energy in accordance with continuous operation, when the amount of power storage sensed by the sensing unit 23 falls below a predetermined value, the transmitting unit 24 operates the operating signal. Generates and sends the generated operation signal.

Accordingly, the receiving unit 32 of the laser device 102 receives the operating signal wirelessly transmitted from the operating object 101, and the laser emitting unit 31 operates by the operating signal to emit the laser.

Subsequently, the laser beam is reflected by the reflector 103 and then enters the photovoltaic cell unit 21 of the operating object 101, and the photovoltaic cell unit 21 converts the incident laser into electrical energy to charge it.

Meanwhile, the time checking unit 33 of the laser device 102 checks the operating time of the laser emitting unit 31, and when the time checked by the time checking unit 33 reaches a predetermined time, the laser is checked. The operation of the launch unit 31 is stopped. Of course, the energy required for the operation of the laser device 102 is by general wired power.

Although the above embodiment detects the amount of power storage automatically and uses the automatic charging method, it is natural that the laser device can be manually operated depending on the application. In addition, it is possible to adjust the firing direction of the laser emitted from the laser device, and furthermore, it is possible to transmit the power to a plurality of operating objects by adjusting the laser firing direction by a single laser device.

In addition, in the above-described embodiment, after checking the operating time of the laser emitter 31 in the time checking part 33, the laser emitter 31 is stopped when a certain time elapses. When the amount of power storage is sensed by the sensing unit 23 of the operation object 101, when the amount of power storage exceeds a predetermined value, the transmitter 24 generates an operation stop signal and wirelessly transmits the operation stop signal. When received by the receiver 32 of the laser device 102, it is also possible to implement to stop the operation of the laser emitter 31.

In addition, according to the implementation, it is also possible to introduce a ubiquitous concept to separately configure the control unit of the operating object and the control unit of the laser device (which may be configured as one control unit), and to wirelessly control the control unit. will be.

As described above, the detailed description of the present invention has been made by the embodiments with reference to the accompanying drawings. However, since the above-described embodiments have only been described with reference to preferred embodiments of the present invention, the present invention is limited to the above embodiments. It should not be understood that the scope of the present invention is to be understood by the claims and equivalent concepts described below.

As described in detail above, according to the present invention, by eliminating the power consumption system by the consumable battery or the wire to the operating object, there is no problem such as trouble, unexpected energy depletion of the battery, difficulty in processing the wire. It works.
