At this time, when the power source level of the first unmanned device falls below a predetermined reference, a replacement signal is generated from the first unmanned device and transmitted to the unmanned device station (S300). Subsequently, the second unmanned device waiting for the unmanned device station is moved to a service location of the first unmanned device according to the replacement signal generated from the first unmanned device, thereby replacing the first unmanned device (S400). 2 The first unmanned device is returned to the charging station and charged as the unmanned device moves (S500).

Referring to FIG. 1B, a user client 10 is provided in which an area and a time at which a service is provided by an unmanned device is determined by a user. In the present invention, the user client 10 may be a user terminal of a web service such as the Internet, and the information input by the user client 10 is provided to the Internet server 20 connected to the user terminal.

Since at least one charging station information is input to the server 20 in the exemplary embodiment of the present invention, the server 20 determines the unmanned device station 30 usable at a region and a time input by the user. . Thereafter, the server 20 provides the information input by the user to the user-determined unmanned device station 30.

Thereafter, the unmanned device station 30 oscillates an unmanned device (first unmanned device 41) that collects information in a corresponding area, collects information in the corresponding area, and then uses a user client (eg, a server). 10) to provide this.

Hereinafter, a sustainable service method using an unmanned device having a limited power source in an internet based unmanned device service according to the present invention will be described.

The present invention is to replace the two or more unmanned devices automatically based on the available level (level, power) of the power source (power, fuel, etc.) in order to solve the problem of the conventional unmanned device operation described above, and to provide continuous remote service through the Internet. Provide a way to. In one embodiment of the present invention, the unmanned device is any mobile means that can be remotely operated, and the service is any service provided by the unmanned device (for example, image information of a specific region). Including, the service range may vary depending on the type and purpose of the unmanned device, all belong to the scope of the present invention.

5 is a step diagram of a method for operating an unmanned device according to an embodiment of the present invention.

Referring to FIG. 5, the method first checks the power level of the first unmanned device providing service in a specific region (S110). At this time, the identification and detection of the power source level may be performed by a separate detection means provided in the unmanned apparatus.

Thereafter, when the power source level falls below a predetermined reference, a replacement signal of the unmanned device is generated from the first unmanned device (S120). In one embodiment of the present invention, the predetermined criterion is changed based on a distance between an unmanned device and a power source rechargeable station (charging station). If the distance is close, the amount of power required when returning to the actual charging station is small, so that the predetermined criterion is lowered. On the contrary, if the distance between the service providing position and the charging station is far, the amount of power consumed upon returning becomes large, thus increasing the predetermined criterion. That is, in the present invention, the predetermined criterion is based on the service time that the first unmanned device should provide for the time required for the power (first power) and the replacement second unmanned device to move to the first unmanned device location. Corresponds to the level covering the power (second power), which is varied by the distance from the charging station as a variable.

Thereafter, the second unmanned device waiting for the charging station is moved to the position of the first unmanned device according to the replacement signal generated from the first unmanned device (S130). In an embodiment of the present invention, the first unmanned device and the second unmanned device can communicate with each other, the location information of the first unmanned device can be transmitted to the second unmanned device, and the location information of the second unmanned device It may be sent back to the first unmanned device. Therefore, whether the second unmanned device is close to the position of the first unmanned device within a predetermined range may be determined based on the location information of the second unmanned device.

According to an embodiment of the present invention, it is determined whether the first unmanned device and the second unmanned device are close to each other within a predetermined range according to the location information transmitted from the second unmanned device. The service provided by the first unmanned device is stopped, and the second unmanned device continuously takes the service and provides the user. Thereafter, the second unmanned device moves to the service providing position of the first unmanned device, and as the second unmanned device provides the service, the first unmanned device returns to the charging station, and after returning, the first unmanned device The power source of is recharged (S140).

When falling below a reference value considering the travel time of the unmanned device 120, the controller of the unmanned device operating system according to the present invention generates a replacement signal of the first unmanned device, the second unmanned device 120 in accordance with the replacement signal ) Leaves the charging station 130 and moves to the position where the first unmanned device 110 is providing service (see FIG. 8).

9 and 10, as the second unmanned device 120 approaches the service providing position of the first unmanned device 110, the first unmanned device 110 stops the service of taking a picture. Return to the charging station 130 (see FIG. 6).

Referring to FIG. 11, the first unmanned apparatus 110 returned to the charging station 130 is charged. The present invention performs the above unmanned device replacement and continuous service provision in an automatic manner, so that the user does not need to manually command the replacement of the actual unmanned device. In order to provide such a service, as described above, it is very important to set a standard (amount of power) for moving a waiting unmanned device from an unmanned device currently providing a service.

Accordingly, the unattended wireless charging apparatus according to the present invention should include a detection means for detecting a power source level, and a communication means for transmitting the power source level detected by the detection means and location information providing a service to the controller. In one embodiment of the present invention, the unmanned device is a movable means that can be moved according to a remote operation, such as an aircraft or a vehicle.

Hereinafter, a method of determining a power level that becomes an unmanned device replacement criterion according to an embodiment of the present invention will be described.

There is a first unmanned device that provides a service for acquiring weather information in a specific region, where power consumption is 1000 mA while the first unmanned device is at a speed of 5 m / s while power consumption is 1500 mA Assume that the charging station is 300 meters away and the second unmanned equipment is 500 meters away.

The time required for the new second unmanned aerial vehicle to reach the first unmanned aerial vehicle location is 500/5 = 100 seconds, and the amount of power consumed by the first unmanned aerial vehicle (stopped) for 100 seconds is 1000 x 100 = 100,000 mA.

In addition, the time required for the first unmanned device to reach the charging station is 400/5 = 60 seconds, and power consumption during the movement is 60 × 1500 mA-90,000 mA. Therefore, the sum of the power consumed until the arrival of a new unmanned vehicle and the power consumed when returning to the charging station is 190,000 mA. Therefore, the threshold amount of power generating a replacement signal by a new unmanned apparatus should be at least 190,000 mA.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims. It will be possible.
