Pairing method and pairing system

[Technical Field]

0001The present invention relates to a pairing method and pairing system that associate and link two devices.

[Background of Related Art]

0002When two devices are used in a one-to-one relation, such as a main body device and an auxiliary device of a remote controller or the like in a set top box, the main body device and the auxiliary device may be paired. Pairing is generating a common encryption key and the main device storing identification information (for example, a Bluetooth [registered trademark] address) of the auxiliary device after establishing, for example, a Bluetooth connection between the two devices. Storing the common encryption key and the identification information of the auxiliary device enables sending and receiving information with the auxiliary device without reconfiguration in a next and subsequent Bluetooth connection and executing functions of a connected device.

0003However, because it is unclear in a manufacturing process which main body device is paired to which auxiliary device, a pairing setting generally needs to be set by purchasers of the device themselves and is time consuming. A manufacturer or seller of the device can perform the pairing setting immediately before packaging the main body device and the auxiliary device, but in this case, there is still a possibility that an enclosure may become scratched or dirty because setting is done by hand.

0005A technique of pairing without contact by setting a communication mode from an external base station is disclosed in Patent Document 1, but this is time consuming because the communication mode needs to be set from the external base station.

[Summary of the Invention]

[Detailed Description of Embodiments]

(First Example)

0032Embodiments of a pairing method and pairing system will be described below with reference to drawings. One or more embodiments of the present invention illustrate examples of the pairing method and the pairing system for embodying a technical concept of the present invention and are not meant to specify the present invention to these pairing methods and pairing systems, being equally applicable to pairing methods and pairing systems of other embodiments included in the scope of patent claims.

0033<figref idref="f0001">FIG. 1</figref> is a diagram illustrating the pairing system of one or more embodiments of first example of the present invention. A pairing system 1 of one or more embodiments of the present invention comprises a power supply device 10, which may include two power supply elements (exemplary details described below), a main body device 20 and an auxiliary device 30, each comprising power receiving elements, for example an antenna, (exemplary details described below). In the embodiment of <figref idref="f0001">Fig. 1</figref>, the main body device 20 and an auxiliary device 30 are packaged in a case 100. The power supply device 10 comprises power supply elements 11 and 12. Materials and shapes of the power supply elements 11, 12 are not limited in particular. As an example, each of the power supply elements 11, 12 may comprise a coil module having a shape that spirals toward a center of a spiral in a top surface view.

0034The main body device 20 may be, for example, a main body in a set top box, and the auxiliary device 30 may be, for example, a device such as a remote controller or a headset in the set top box. The main body device 20 and the auxiliary device 30 comprise power receiving elements 21,31 that correspond to the power supply elements 11 and 12, respectively.

0035When AC power is supplied to the power supply elements 11, 12, an alternating magnetic field is generated in a direction perpendicular to a power supply surface (a y-axis direction in <figref idref="f0001">FIG. 1</figref>). An induced current is excited in the power receiving element 21, 31 brought near the power supply elements 11, 12 by this alternating magnetic field, transmitting power. Moreover, it is possible to send and receive information by superimposing various types of information on high-frequency power of a non-contact power supply using a frequency (communication frequency) that differs from the high-frequency power of the non-contact power supply. The power supply elements 11, 12 and the power receiving elements 21, 22, in addition to sending and receiving power, function as a communication part that can communicate with a power supply source or a power supply destination.

0036The main body device 20 may further comprise a controller 22 and a memory 23, such as for example a flash ROM. The controller 22 may be a control means for controlling the entire main body device 20. The controller 22 includes a CPU 221, a ROM 222, and a RAM 223. The ROM 222 stores software and programs executed by the controller 22 and parameters and data needed to execute the software and the programs. The CPU 221 executes the various types of software and programs stored in the ROM 222. The RAM 223 temporarily stores data obtained during various types of processes and data obtained as a result of the various types of processes. The CPU 221, the ROM 222, the RAM 223, and the like are connected via a bus. A portion or an entirety of the CPU 221, the ROM 222, and the RAM 223 may be integrated into one chip.

0037In one or more embodiments of the present invention, software for performing pairing setting is stored in the ROM 222. When the software for performing pairing setting is started (executed), a process for pairing setting with another device is executed.

0038Specifically, the CPU 221 of the controller 22 executes the software for performing pairing setting stored in the RAM 222 when non-contact power supply between the power receiving element 21 and the power supply element 11 begins. Information, such as identification information of the auxiliary device 30 that will be described below, obtained by executing the software for performing pairing setting may be stored in the memory 23.

0039The auxiliary device 30 further comprises a controller 32 and a memory 33, such as for example a flash ROM. The controller 32 may be a control means for controlling the entire auxiliary device 30. The controller 32 includes a CPU 321, a ROM 322, and a RAM 323. The ROM 322 stores software and programs executed by the controller 22 and parameters and data needed to execute the software and the programs. The CPU 321 executes the various types of software and programs stored in the ROM 322. The RAM 323 temporarily stores data obtained during various types of processes and data obtained as a result of the various types of processes. The CPU 321, the ROM 322, the RAM 323, and the like are connected via a bus. A portion or an entirety of the CPU 321, the ROM 322, and the RAM 323 may be integrated into one chip.

0040In one or more embodiments of the present invention, software for performing pairing setting is stored in the ROM 322. When the software for performing pairing setting is started (executed), a process for pairing setting with another device is executed.

0041Specifically, the CPU 321 of the controller 32 executes the software for performing pairing setting stored in the RAM 322 when non-contact power supply between the power receiving element 31 and the power supply element 12 begins. Identification information of the auxiliary device 30 may be stored in the memory 33. According to one or more embodiments, the stored identification information of the auxiliary device 30 may comprise, for example, a manufacture lot number.

0042An exemplary process from start to end of the pairing setting in the pairing system 1 according to one or more embodiments of the present invention will be described below with reference to <figref idref="f0002">FIG. 2. FIG. 2</figref> is a flowchart illustrating an exemplary process leading to pairing completion.

0043In steps S01, S11, the controllers 22, 32 determine respectively whether non-contact power supply has begun. If non-contact power supply has begun (Y at steps S01, S11), the process proceeds to steps S02, S12, and if non-contact power supply has not begun, the process returns to steps S01, S11. When the main body enclosure 20 and the auxiliary device 30 are packaged in the case 100, starting non-contact power supply may supply power to the controllers 22, 32 and start the process in <figref idref="f0002">FIG. 2</figref>. In this case, the process at and after steps S02, S12 may be performed without performing the determination at steps S01, S11.

0044At steps S02, S12, the CPUs 221, 321 of the controllers 22, 32 execute the software for pairing setting. In step S13, the controller 32 obtains identification information of its own device 30 from the memory 33 and superimposes this information on high-frequency power of the power supply device 10. The identification information of the auxiliary device 30 superimposed on high-frequency power is output to the controller 22 via non-contact power supply between the power supply element 11 and the power receiving element 21.

0045In step S03, it is determined whether the controller 22 obtained the identification information of the auxiliary device 30. If the identification information of the auxiliary device 30 has been obtained (Y at step S03), the process proceeds to step S04 and stores the identification information of the auxiliary device 30 in the memory 23. Pairing setting is thereby completed, and in the next and subsequent times, the auxiliary device 30 can be used with the main body device 20 without requiring pairing setting.

0046According to one or more embodiments of the present invention, the software for performing pairing setting is executed in two devices that are objects of pairing setting with non-contact power supply as a trigger. When the software is executed, one device outputs the identification information of its own device to another device, and the latter device stores the identification information. Pairing setting is thereby completed. Because this pairing setting is executed by starting non-contact power supply, pairing setting can be easily executed not only before but also after the two devices are packaged into one case.

(Second Example)

0047<figref idref="f0003">FIG. 3</figref> is a diagram illustrating a pairing system of one or more embodiments of the present invention. In the first example, the power supply element and the power receiving element functioned as the communication part.

The main body device 40 and the auxiliary device 50 have power receiving elements 41, 51 that correspond to the power supply elements 11 and 12, respectively.

0050When AC power is supplied to the power supply elements 11, 12, an alternating magnetic field is generated in a direction perpendicular to a power supply surface (a y-axis direction in <figref idref="f0003">FIG. 3</figref>). An induced current is excited in the power receiving element 41, 51 brought near the power supply elements 11, 12 by this alternating magnetic field, transmitting power.

0051The main body device 40 further comprises a controller 42, a memory 43 such as a flash ROM, and a communication part 44. The controller 42 may be a control means for controlling the entire main body device 40. The controller 42 includes a CPU 421, a ROM 422, and a RAM 423. The ROM 422 stores software and programs executed by the controller 42 and parameters and data needed to execute the software and the programs. The CPU 421 executes the various types of software and programs stored in the ROM 422. The RAM 423 temporarily stores data obtained during various types of processes and data obtained as a result of the various types of processes. The CPU 421, the ROM 422, the RAM 423, and the like are connected via a bus. A portion or an entirety of the CPU 421, the ROM 422, and the RAM 223 may be integrated into one chip.

0052In one or more embodiments of the present invention, software for performing pairing setting is stored in the ROM 422. When the software for performing pairing setting is started (executed), a process for pairing setting with another device is executed.

0053Specifically, the CPU 421 of the controller 42 executes the software for performing pairing setting stored in the RAM 422 when non-contact power supply between the power receiving element 41 and the power supply element 11 begins. Information (identification information of the auxiliary device 50 that will be described below) obtained by executing the software for performing pairing setting is stored in the memory 43. The communication part 44 sends and receives information with the external wireless communication device 70 that will be described below.

0054The auxiliary device 50 further comprises a controller 52, a memory 53 such as a flash ROM, and a communication part 54. The controller 52 may be a control means for controlling the entire auxiliary device 50. The controller 52 comprises a CPU 521, a ROM 522, and a RAM 523. The ROM 522 stores software and programs executed by the controller 52 and parameters and data needed to execute the software and the programs. The CPU 521 executes the various types of software and programs stored in the ROM 522. The RAM 523 temporarily stores data obtained during various types of processes and data obtained as a result of the various types of processes. The CPU 521, the ROM 522, the RAM 523, and the like are connected via a bus. A portion or an entirety of the CPU 521, the ROM 522, and the RAM 523 may be integrated into one chip.

0055In one or more embodiments of the present invention, software for performing pairing setting is stored in the ROM 522. When the software for performing pairing setting is started (executed), a process for pairing setting with another device is executed.

0056Specifically, the CPU 521 of the controller 52 executes the software for performing pairing setting stored in the RAM 522 when non-contact power supply between the power receiving element 51 and the power supply element 12 begins. Identification information of the auxiliary device 50 is stored in the memory 53. As the identification information of the auxiliary device 50 stored in one or more embodiments of the present invention, a manufacture lot number, a Bluetooth address, a MAC address, and an IP address are illustrated. The communication part 54 sends and receives information with the external wireless communication device 70 that will be described below.

0057The ROM writer 60 is an information processing device such as a personal computer, and the external wireless communication device 70 is connected to the ROM writer 60. The ROM writer 60 and the communication part 44, 54 are connected by wireless communication such as Bluetooth, Wi-Fi (registered trademark), or P2P, and the communication parts 44 and 54 send and receive information via the external wireless communication device 70.

0058A process from when pairing setting starts to when pairing setting ends in the pairing system 1 of one or more embodiments of the present invention will be described below with reference to <figref idref="f0004">FIG. 4. FIG. 4</figref> is a flowchart illustrating an exemplary process leading to pairing completion.

0059In steps S21, S31, the controllers 42, 52 determine respectively whether non-contact power supply has begun. If non-contact power supply has begun (Y at steps S21, S31), the process proceeds to steps S22, S32, and if non-contact power supply has not begun, the process returns to steps S21, S31. In a situation where the main body enclosure 40 and the auxiliary device 50 are packaged in the case 100, because starting non-contact power supply supplies power to the controllers 42, 52 and starts the process in <figref idref="f0004">FIG. 4</figref>, in this situation, the process at and after steps S22, S32 may be performed without performing the determination at steps S21, S31.

0060At steps S22, S32, the CPUs 421, 521 of the controllers 42, 52 execute the software for pairing setting. In step S33, the controller 52 obtains identification information of its own device from the memory 53 and sends this information to the external wireless communication device 70 via the communication part 54. The identification information of the auxiliary device 50 sent to the external wireless communication device 70 is stored in the ROM writer 60 and, further, output to the controller 42 via the external wireless communication device 70 and the communication part 44.

0061It is determined in step S23 whether the controller 42 obtained the identification information of the auxiliary device 50. If the identification information of the auxiliary device 50 has been obtained (Y at step S23), the process proceeds to step S24 and stores the identification information of the auxiliary device 50 in the memory 43. Pairing setting is thereby completed, and in the next and subsequent times, the auxiliary device 50 can be used with the main body device 40 without requiring pairing setting.

As the identification information of the auxiliary device 90 stored in one or more embodiments of the present invention, a manufacture lot number, a Bluetooth address, a MAC address, and an IP address are illustrated. The communication part 94 sends and receives information with the communication part 84. The communication part 84 and the communication part 94 are connected by wireless communication such as Bluetooth, Wi-Fi, or P2P.

0073A process from start to end of the pairing setting in the pairing system 1 will be described below with reference to <figref idref="f0006">FIG. 6. FIG. 6</figref> is a flowchart illustrating an exemplary process leading to pairing completion.

0074In steps S41, S51, the controllers 82, 92 determine respectively whether non-contact power supply has begun. If non-contact power supply has begun (Y at steps S41, S51), the process proceeds to steps S42, S52, and if non-contact power supply has not begun, the process returns to steps S41, S51. In a situation where the main body enclosure 80 and the auxiliary device 90 are packaged in the case 100, because starting non-contact power supply supplies power to the controllers 82, 92 and starts the process in <figref idref="f0006">FIG. 6</figref>, in this situation, the process at and after steps S42, S52 may be performed without performing the determination at steps S41, S51.

0075In one or more embodiments of the present invention, identification information unique to the power supply device 10 (for example, information indicating the manufacture lot number) is superimposed on high-frequency power of non-contact power supply.

0076At steps S42, S52, the CPUs 821, 921 of the controllers 82, 92 execute the software for pairing setting.

0077At steps S43, S53, the controllers 82, 92 extract the identification information of the power supply device 10 superimposed on high-frequency power of non-contact power supply.

0078At step S44, the controller 82 determines whether the identification information of the power supply device 10 extracted at step S43 matches the identification information of the power supply device 10 extracted by the controller 92 at step S53. If the identification information match (Y at step S44), the process proceeds to step S45, and if the identification information do not match, the process ends.

0079At step S45, the controller 82 requests the identification information of the auxiliary device 90 from the controller 92.

0080At step S54, the controller 92 obtains the identification information of its own device from the memory 93. The obtained identification information of its own device is output to the controller 82 via the communication part 94 and the communication part 84.

0081It is determined in step S46 whether the controller 82 obtained the identification information of the auxiliary device 90. If the identification information of the auxiliary device 90 has been obtained (Y at step S46), the process proceeds to step S47 and stores the identification information of the auxiliary device 90 in the memory 83. Pairing setting is thereby completed, and in the next and subsequent times, the auxiliary device 90 can be used with the main body device 80 without requiring pairing setting.

0082According to one or more embodiments of the present invention, the same effects as one or more embodiments of the first example may be exhibited.

(Fourth Example)

0083In one or more embodiments of the present invention described above, the software for pairing setting is executed with starting non-contact power supply as the trigger. However, the present invention is not limited thereto and may execute software for pairing setting when a signal that serves as a trigger for executing the software for pairing setting and that is superimposed on high-frequency power of non-contact power supply is received.

0084A process from start to end of a pairing setting in a pairing system 1 will be described below with reference to <figref idref="f0007">FIG. 7. FIG. 7</figref> is a flowchart illustrating an exemplary process leading to pairing completion. One or more embodiments of a fourth example of the present invention will be described as a modified example of the first example but is also applicable to the second and third examples.

0085Steps S61, S63 to S65, S71, and S73 to S74 in the flowchart in <figref idref="f0007">FIG. 7</figref> may respectively be the same as steps S01, S02 to S04, S11, and S12 to S13, and descriptions thereof will therefore be omitted.

0086At steps S62, S72, controllers 22, 32 determine respectively whether the signal that serves as the trigger for pairing setting is superimposed on high-frequency power of non-contact power supply. If the signal that serves as the trigger for pairing setting is superimposed on high-frequency power of non-contact power supply (Y at steps S62, S72), the process proceeds to step S63, S73, and if the signal that serves as the trigger for pairing setting is not superimposed on high-frequency power of non-contact power supply (N at steps S62, S72), the process returns to steps S62, S72.

0087According to one or more embodiments of the present invention, the same effects as the first example may be exhibited. Additionally, because the software for pairing setting is only executed when the signal that serves as the trigger for pairing setting is superimposed on high-frequency power of non-contact power supply, pairing setting can be executed or updated at a desired timing.

(Fifth Example)

0088In the second and third examples, the identification information of the auxiliary device is sent and received by the communication part of the auxiliary device directly or indirectly communicating with the communication part of the main body device. However, if a plurality of main body devices executes software for pairing setting and/or a plurality of auxiliary devices executes the software for pairing setting, there is a possibility that the main body device and the auxiliary device that the user desires are not paired. Therefore, one or more embodiments of a fifth example of the present invention provide a pairing system that can reliably perform pairing even in such a situation.

0089Embodiments of the fifth example of the present invention will be described as a modified example of the third example but is of course also applicable to the first and fourth examples. In one or more embodiments of the fifth example of the present invention, a power supply device 10 superimposes a high frequency indicating identification information of the power supply device 10 on high-frequency power of non-contact power supply. Controllers 82, 92 obtain the identification information of the power supply device 10 superimposed on high-frequency power of non-contact power supply.

0090Furthermore, the controllers 82, 92 can search a device having the identification information of the power supply device 10 (a same identification number as an extracted identification number of the power supply device) via communication parts 84, 94. For example, the identification information of the auxiliary device 90 is stored in a memory 84 when the controller 82 searches the auxiliary device 90 as the auxiliary device having the identification information of the power supply device 10.

0091According to one or more embodiments of the fifth example of the present invention, the same effects as the second and third examples may be exhibited. Additionally, because objects for pairing setting are specified based on the identification information of the power supply device, pairing setting can be performed reliably even when there is the plurality of main body devices or the plurality of auxiliary devices.

0092Although the disclosure has been described with respect to only a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that various other embodiments may be devised without departing from the scope of the present invention. Accordingly, the scope of the invention should be limited only by the attached claims.
