Patent Application
20140342664
The present invention relates to a pairing method and pairing system that associates and links two devices.
When 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.
However, 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.

A process from start to end of the pairing setting in the pairing system 1 will be described below with reference to
In 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
In 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.
At steps S42, S52, the CPUs 821, 921 of the controllers 82, 92 execute the software for pairing setting.
At 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.
At 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.
At step S45, the controller 82 requests the identification information of the auxiliary device 90 from the controller 92.
At 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.
It 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.

According to one or more embodiments of the present invention, the same effects as one or more embodiments of the first example may be exhibited.
In 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.
A process from start to end of a pairing setting in a pairing system 1 will be described below with reference to
Steps S61, S63 to S65, S71, and S73 to S74 in the flowchart in
At 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.
According 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.
In 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.
Embodiments 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.
Furthermore, 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.
According 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.
Although 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.
