Rather, these embodiments are provided so that this disclosure will be thorough and complete, And advantages of the present invention are defined by the description of the claims.
It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. In the present specification, the singular form includes plural forms unless otherwise specified in the specification. &Quot; comprises "and / or" comprising ", as used herein, unless the recited component, step, operation, and / Or added.
Prior to describing the preferred embodiments of the present invention, the background of the present invention will be described below in order to facilitate the understanding of those skilled in the art.
Wireless charging technology is also called noncontact charging, and it is largely classified into a method using electromagnetic induction, a resonance method, and an RF / Micro Wave Radiation method.
In the electromagnetic induction method, the charging pad and the two coils inside the mobile phone cause the induction current to charge the battery. In the resonance method, power is transmitted to the transmitting and receiving end at a certain distance (for example, 1 to 2 meters) And the radio wave radiation method is a method of converting electrical energy into microwave and transmitting it.
According to the related art, various nodes are formed with a structure in which a rechargeable battery based on a wireless communication is used as a battery.
According to this conventional technology, in the case of wireless charging of a secondary battery with a risk of battery discharge, it is necessary to increase the size of coils in long-distance wireless power transmission, space due to use of additional repeaters and problems of power leakage, Problems such as generated heat are generated.
The present invention has been proposed in order to solve the problems of the related art described above. The present invention proposes a technique of confirming the position of a node requiring charging and performing wireless charging by moving to the position of the node. 1 to 3, a preferred embodiment of the present invention will be described.

FIG. 2 is a flowchart illustrating a mobile automatic wireless charging method according to an embodiment of the present invention. FIG. 3 is a flow chart illustrating a process of checking remaining battery power and transmitting information in a wireless charging receiving node of a mobile automatic charging system according to an embodiment of the present invention .
The mobile automatic wireless charging method according to an embodiment of the present invention includes checking whether a received message is a battery charging request message (S200), if the received message is a battery charging request message, (S250), and a step (S300) of performing a wireless charging by approaching a predetermined wireless power transmission distance to the wireless charging receiving node whose location information has been confirmed.
After the initialization step S100, the mobile automatic wireless charging device receives a message (S150) and determines whether the received message is a battery charging request message (S200).
If the received message is a battery charge request message, the location information of the wireless charge receiving node is checked based on the ID information and the location information of the wireless charge receiving node included in the battery charge request message (S250).
At this time, in step S250, the location information of the wireless charging receiving node is confirmed using at least one of the GPS signal, the pre-registered map information, and the acquired image information.
When the position of the wireless charging node is confirmed, the mobile automatic charging apparatus accesses the wireless charging node within a predetermined wireless power transmission distance and performs wireless charging (S300).
When the charging of the wireless charging node is completed, the portable automatic charging apparatus acquires and updates the current location information of the wireless charging node (S350).
If it is determined in step S200 that the received message is not the battery charge request message, it is determined whether the battery status check message is requested (S400).
In other words, according to the embodiment of the present invention, even when the battery charging request message is not received from the wireless charging node, the battery state message is transmitted according to the predetermined period, It is possible to monitor the operation of the apparatus.
If it is determined in step S400 that it corresponds to the battery status check message requesting period, the node transmits a battery status check message to the wireless charge receiving node, and receives the node ID information and the battery remaining amount information from the wireless charge receiving node responding thereto ).
In step S600, the wireless charging receiving node determines whether the battery remaining amount is less than a predetermined threshold value in step S550 after the initial charging step S500.
If the battery remaining amount is equal to or less than the predetermined threshold value, a battery charge request message including its own node ID and location information is transmitted (S650), and in response, wireless charging is received from the mobile automatic wireless charging device approaching its own location (S700).
If the battery remaining amount is not equal to or less than the predetermined threshold value, it is determined whether the battery status confirmation message is received from the mobile automatic charging device in accordance with the predetermined period (S800). If the battery status confirmation message is received And transmits it to the mobile automatic wireless charging device (S850).
The embodiments of the present invention have been described above. 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 by the appended claims. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense. The scope of the present invention is defined by the appended claims rather than by the foregoing description, and all differences within the scope of equivalents thereof should be construed as being included in the present invention.
