Hereinafter, a control method of the wireless charging system according to the present invention will be described in detail with reference to FIGS. 1 to 11.
FIG. 6 is a flowchart illustrating a control method of the wireless charging system according to a first embodiment of the present invention.
First, in A4WP scheme wireless charging, wireless charging equipment 100 (alternatively, a PTU) transmits a power beacon signal at a predetermined time interval.
Further, one or more terminals 200 including a PRU adjacent to the corresponding wireless charging equipment 100 receive the power beacon signal transmitted from the wireless charging equipment 100 and establishes connection (alternatively, communication) with the corresponding wireless charging equipment 100 based on the received power beacon signal.
As an example, the wireless charging equipment 100 transmits (alternatively, propagates) the power beacon signal to a first terminal and a second terminal which include PRUs adjacent to the corresponding wireless charging equipment 100, respectively. Further, each of the first terminal and the second terminal receives the power beacon signal transmitted from the wireless charging equipment 100 and communicates with the corresponding wireless charging equipment 100 based on the received power beacon signal (S610).
Thereafter, the wireless charging equipment 100 verifies (alternatively, determines) the number of terminals connected to the corresponding wireless charging equipment 100. In this case, the terminal connected to the wireless charging equipment 100 charges the battery provided in the corresponding terminal based on the charging signal transmitted from the corresponding wireless charging equipment 100.
As an example, the wireless charging equipment 100 verifies the first terminal and the second terminal connected with the corresponding wireless charging equipment 100 (S620).
Thereafter, the wireless charging equipment 100 verifies (alternatively, determines/predicts) an empty time period (alternatively, an idle/standby time period) without transmitting the corresponding charging signal to one or more terminals 200 connected with the corresponding wireless charging equipment 100 in a time slot (alternatively, a total data transmittable time) based on the verified number of terminals, in order to verify a time period (alternatively, a time/time zone) without transmitting the charging signal to one or more terminals 200 connected with the corresponding wireless charging equipment 100.
That is, the wireless charging equipment 100 verifies the remaining time period (alternatively, the empty time period/empty time zone) except for the time of transmitting the charging signal to one or more terminals in the time slot based on the verified number of terminals. Here, the charging signal is transmitted at the predetermined time interval.
As an example, as illustrated in FIG. 7, the wireless charging equipment 100 verifies the remaining time period 730 (alternatively, time zone) except for a time zone 721 for transmitting the charging signal to the first terminal and a time zone 722 for transmitting the charging signal to the second terminal in the time slot 410. In this case, the charging signal transmitted to the first terminal and the second terminal may be transmitted at the predetermined time interval (for example, 250 ms) (S630).
Thereafter, the wireless charging equipment 100 transmits a beacon signal including additional information to one or more terminals 200 connected with the corresponding wireless charging equipment 100 based on the verified empty time period, respectively. Here, the additional information includes coupon information, product information, and the like in a store (alternatively, an area/region) where the corresponding wireless charging equipment 100 is installed (alternatively, provided).
That is, the wireless charging equipment 100 verifies a time period enough to transmit the additional information in the verified empty time period and transmits the beacon signal including the corresponding additional information to one or more terminals 200 in the verified time period enough to transmit the corresponding additional information. In this case, the wireless charging equipment 100 may also transmit the beacon signal by a broadcasting scheme.
As an example, the wireless charging equipment 100 verifies a time period 731 enough to transmit the beacon signal including the additional information (for example, including the coupon information, the product information, and the like) in an empty time period 730 illustrated in FIG. 7 and transmits a beacon signal 740 including the corresponding additional information by the broadcasting method in the verified time period 731 (alternatively, within the verified time period 731). That is, when the empty time period 730 illustrated in FIG. 7 is 150 ms and an area corresponding to about 50 ms is required in order to transmit the beacon signal including the additional information, the wireless charging equipment 100 transmits the beacon signal 740 including the corresponding additional information by the broadcasting method within the corresponding empty time period 730 (for example, at the time when early 50 ms elapses in 150 ms which is the empty time period) (S640).
Thereafter, each of one or more terminals 200 receives the beacon signal including the additional information transmitted from the wireless charging equipment 100.
Further, the corresponding terminal 200 performs an operation (alternatively, a control) corresponding to the additional information included in the corresponding beacon signal based on the received beacon signal.
As an example, the terminal 200 receives the beacon signal including the additional information (for example, including the coupon information, the product information, and the like) transmitted from the wireless charging equipment 100 and displays the additional information included in the received beacon signal on the display unit (not illustrated) (S650).
FIG. 8 is a flowchart illustrating an operation method of the wireless charging system according to a second embodiment of the present invention. FIG. 9 is a diagram illustrating a message which may be displayed on a terminal while operating the wireless charging system according to the second embodiment of the present invention.
First, communication between the wireless charging equipment 100 and the terminal 200 is performed (S810). A wireless chargeable range of the wireless charging equipment 100 may be formed to be equal to or smaller than a communicable range.
As a result, when the terminal 200 is positioned within the communicable range of the wireless charging equipment 100, but positioned out of the wireless chargeable range, the wireless charging between the wireless charging equipment 100 and the terminal 200 is impossible.
The present invention is to transfer the information of the terminal 200 collected through charging to the service providing device 300 and will be described on the assumption that the terminal 200 is positioned in the wireless chargeable range of the wireless charging equipment 100.
Accordingly, in step S810, the performing of the communication between the wireless charging equipment 100 and the terminal 200 means that the terminal 200 is positioned in the wireless chargeable range of the wireless charging equipment 100 to simultaneously perform the wireless charging and the communication.
In step S810, when the communication is performed, next, whether to provide the terminal information is verified (S820).
As illustrated in FIG. 9, in the case where the terminal 200 is registered to agree to provide the terminal information to the wireless charging equipment 100 or the terminal 200 agrees to provide the terminal information even though the terminal 200 is not pre-registered in the wireless charging equipment 100, the terminal 200 may provide the wireless charging power and simultaneously, collect the terminal information.
Next, the wireless charging equipment 100 supplies the charging power to the terminal 200 and simultaneously, collects the terminal information from the terminal 200 (S830). The process of collecting the terminal information from the terminal 200 may be performed by communication using the BLE scheme.
The terminal information may include information collected through the charging function of the wireless charging equipment 100 such as a place for wireless charging, a time for wireless charging, a charging frequency, the number of terminals which are simultaneously charged in order to determine dense population, terminals charged frequently on a wireless charging history together, and a charging amount of the terminal, and personal information such as gender and age of the user of the terminal 200.
Here, the information on the place for wireless charging may be acquired by area information of a store (alternatively, an area/region) where the corresponding wireless charging equipment 100 is installed (alternatively, provided).
Next, the collected terminal information is transferred to the service providing device 300 through the communication network (S840). The service providing device 300 may receive, edit, and store the terminal information.
FIG. 10 is a flowchart illustrating a control method of the wireless charging system according to a third embodiment of the present invention.
First, in the case where a predetermined event occurs while the terminal 200 is charging through the wireless charging equipment 100, the terminal 200 communicates with the service providing device 300. Here, the predetermined event includes a case where there is no terminal operation for a predetermined time, a case where the terminal 200 enters into a predetermined standby state, a case of immediately after charging starts according to predetermined set information, and the like.
As an example, while the terminal 200 is charging through the wireless charging equipment 100, when there is no operation for the terminal 200 by the user for the predetermined time (for example, 3 minutes), the terminal 200 communicates with the service providing device 300 (S1010).
Thereafter, the terminal 200 generates a firmware version information request signal for the corresponding firmware required for verifying whether to update the firmware installed in the corresponding terminal 200. Here, the corresponding firmware version information request signal includes a kind of firmware installed in the corresponding terminal 200, version information (alternatively, firmware version information) of the firmware installed in the corresponding terminal 200, identification information of the terminal 200, and the like. In this case, the identification information of the terminal 200 includes an MDN, a mobile IP, a mobile MAC, Sim card unique information, a serial number, and the like. Further, the identification information of the terminal 200 may also include an IMSI of a USIM provided in the terminal 200, a unique IMEI of the terminal 200, and the like.
Further, the terminal 200 transmits the generated firmware version information request signal to the service providing device 300.
As an example, the terminal 200 generates the firmware version information request signal including a kind of firmware installed in the corresponding terminal 200, version information of the firmware installed in the corresponding terminal 200, the identification information of the terminal 200, and the like and transmits the generated firmware version information request signal to the service providing device 300 (S1020).
Thereafter, the service providing device 300 receives the firmware version information request signal transmitted from the terminal 200.
Further, the service providing device 300 transmits a firmware version information response signal to the terminal 200 in response to the received firmware version information request signal. Here, the firmware version information response signal includes a kind of firmware installed in the corresponding terminal 200, latest version information of the corresponding firmware, identification information of the terminal 200, and the like.
As an example, the service providing device 300 generates a firmware version information response signal including a kind of firmware installed in the corresponding terminal 200, latest version information (for example, v.1.5) of the corresponding firmware, identification information of the terminal 200, and the like in response to the received firmware version information request signal and transmits the generated firmware version information response signal to the corresponding terminal 200 (S1030).
Thereafter, the terminal 200 receives the firmware version information response signal transmitted from the service providing device 300 in response to the transmitted firmware version information request signal.
Further, the terminal 200 determines (alternatively, verifies) whether to perform the update function of the firmware installed in the corresponding terminal 200 based on the received firmware version information response signal.
That is, the terminal 200 compares the version information of the firmware installed in the corresponding terminal 200 with the latest version information included in the received firmware version information response signal to determine whether the version information of the firmware installed in the corresponding terminal 200 is maintained in the latest state.
As an example, the terminal 200 determines whether the version information of the firmware installed in the corresponding terminal 200 is equal to the latest version information (for example, v.1.5) included in the received firmware version information response signal.
As the determined result, in the case where it is not required to perform the update function of the firmware, the terminal 200 continuously performs the charging function through the wireless charging equipment 100.
That is, as the determined result, when the version information of the firmware installed in the corresponding terminal 200 is the same as the latest version information included in the received firmware version information response signal, the terminal 200 determines that the firmware installed in the corresponding terminal 200 is maintained in the latest state to continuously perform the charging function through the wireless charging equipment 100 without performing the firmware update function.
As an example, when the version information of the firmware installed in the corresponding terminal 200 is the same as the latest version information (for example, v.1.5) included in the received firmware version information response signal, the terminal 200 continuously performs the charging function through the wireless charging equipment 100 without performing the firmware update function (S1050).
Further, as the determined result, when it is required to perform the firmware update function, the terminal 200 performs the update function for the firmware installed in the corresponding terminal 200 by interlocking with the service providing device 300. In this case, when performing the firmware update function, the terminal 200 continuously performs the charging function through the wireless charging equipment 100 and performs the firmware update function through the service providing device 300 in a background state.
That is, as the determined result, when the version information of the firmware installed in the corresponding terminal 200 is different from the latest version information included in the received firmware version information response signal, the terminal 200 determines that the firmware installed in the corresponding terminal 200 is not maintained in the latest state to perform the charging function through the wireless charging equipment 100 and perform the firmware update function through the service providing device 300 in the background state.
As an example, when the version information of the firmware installed in the corresponding terminal 200 is lower than (alternatively, different from) the latest version information (for example, v.1.5) included in the received firmware version information response signal, the terminal performs the firmware update function in the background state.
Further, after the corresponding firmware update function is completed, the terminal 200 performs a rebooting function for the corresponding terminal 200.
Further, after performing the rebooting function, the terminal 200 continuously performs the charging function by interlocking with the wireless charging equipment 100 (S1060).
FIG. 11 is a flowchart illustrating a control method of the wireless charging system according to a fourth embodiment of the present invention.
First, in A4WP scheme wireless charging, wireless charging equipment 200 (alternatively, a PTU) transmits a power beacon signal at a predetermined time interval.
Further, a terminal 200 adjacent to the corresponding wireless charging equipment 100 receives the power beacon signal transmitted from the wireless charging equipment 100.
Further, the terminal 200 generates a PRU advertisement signal in response to the power beacon signal and transmits the generated PRU advertisement signal to the wireless charging equipment 100. Here, the PRU advertisement signal includes unique information (alternatively, a sharing ID) of the PRU included in the corresponding terminal 200, version information of the corresponding PRU, a manufacturing number of the corresponding PRU, identification information of the corresponding terminal 200, and the like. In this case, the identification information of the terminal 200 includes an MDN, a mobile IP, a mobile MAC, Sim card unique information, a serial number, and the like. Further, the identification information of the terminal 200 may also include an IMSI of a USIM provided in the terminal 200, a unique IMEI of the terminal 200, and the like.
Further, the wireless charging equipment 100 receives the PRU advertisement signal transmitted from the terminal 200 receiving the corresponding power beacon signal in response to the transmitted power beacon signal.

As an example, the wireless charging equipment 100 transmits (alternatively, propagates) the power beacon signal to a first terminal and a second terminal which include PRUs adjacent to the corresponding wireless charging equipment 100. Thereafter, each of the first terminal and the second terminal adjacent to the corresponding wireless charging equipment 100 receives the power beacon signal transmitted from the wireless charging equipment 100. Thereafter, the first terminal generates a first PRU advertisement signal and transmits the generated first PRU advertisement signal to the wireless charging equipment 100. Further, the second terminal generates a second PRU advertisement signal and transmits the generated second PRU advertisement signal to the wireless charging equipment 100. Thereafter, the wireless charging equipment 100 receives the first PRU advertisement signal and the second PRU advertisement signal transmitted from the first terminal and the second terminal in response to the transmitted power beacon signal, respectively. Thereafter, the wireless charging equipment 100 communicates with the first terminal based on the received first PRU advertisement signal. Further, the wireless charging equipment 100 communicates with the second terminal based on the received second PRU advertisement signal (S1110).
Thereafter, the wireless charging equipment 100 verifies predetermined class information for the corresponding terminal 200 based on the identification information of the connected terminal 200 (alternatively, unique information of the PRU included in the corresponding terminal 200). Here, the predetermined class information for the corresponding terminal 200 may be information set by the service providing device (not illustrated) based on motion accumulated in one or more stores pre-set by the corresponding terminal 200, region movement information in the store, product purchase history information in the store, and the like.
That is, the wireless charging equipment 100 verifies the class information corresponding to the identification information of the connected terminal 200 in the pre-stored class information for each terminal. In this case, in the case where there is no class information corresponding to the identification information of the corresponding terminal 200 in the pre-stored class information for each terminal, the wireless charging equipment 100 sets (alternatively, verifies/matches) the class of the corresponding terminal 200 as a predetermined minimum class.
As an example, the wireless charging equipment 100 verifies the class information (for example, class C) for the first terminal corresponding to the identification information of the first terminal in the class information for each pre-stored terminal as listed in Table 1 and verifies the class information (for example, class S) for the second terminal corresponding to the identification information of the second terminal (S1120).
Thereafter, the wireless charging equipment 100 allocates one or more channels corresponding to the predetermined class information for the corresponding terminal 200 verified in the plurality of pre-divided channels. Here, the plurality of channels (alternatively, the power transmission capacity) may divide and generate the entire power providable in the corresponding wireless charging equipment 100 into a predetermined minimum power unit.
That is, the wireless charging equipment 100 allocates the number of channels corresponding to the predetermined class information for the corresponding terminal 200 verified in the plurality of pre-divided channels.
As an example, the wireless charging equipment 100 allocates one channel corresponding to the class C which is the verified class information for the first terminal and allocates four channels corresponding to the class S which is the verified class information for the second terminal in the plurality of pre-divided channels as listed in Table 2. Here, the plurality of divided channels may be in a predetermined state as 50 mA which is each minimum unit (S1130).
Thereafter, the wireless charging equipment 100 provides the wireless charging function to the corresponding terminal 200 with the wireless charging intensity (alternatively, wireless charging sensitivity) corresponding to one or more allocated channels.
That is, the wireless charging equipment 100 provides the wireless charging function to the corresponding terminal 200 with the wireless charging intensity corresponding to the number of channels allocated to the terminal.
As an example, the wireless charging equipment 100 provides the wireless charging function to the corresponding first terminal with 50 mA corresponding to one channel set for the first terminal and provides the wireless charging function to the corresponding second terminal with 200 mA (for example, four 50 mA which is the minimum unit are allocated) corresponding to four channels set for the second terminal (S1140).
Thereafter, the corresponding terminal 200 receives the wireless charging function provided from the wireless charging equipment 100.
As an example, the first terminal receives the wireless charging function from the wireless charging equipment 100 providing the power of 50 mA. Further, the second terminal receives the wireless charging function from the wireless charging equipment 100 providing the power of 200 mA (S1150).
