Description

  The present invention relates to a technique for charging a portable information device.

  As portable information devices, smartphones equipped with batteries, mobile phones, tablet terminals, digital cameras, and the like have become widespread and can be charged by connecting a charging cable to a power outlet. In recent years, in order to eliminate the trouble of connecting a charging cable, there is a technique capable of charging by simply placing a portable information device on a charging pad (for example, see Non-Patent Documents 1 and 2). In particular, there is a low-power wireless power transfer technology that has been standardized as an international standard called Qi. This technology is based on an “electromagnetic induction method” in which an electromotive force is generated in a coil on the portable information device side through a magnetic flux generated by passing a current through the coil on the charging pad side. Since the portable information device can be charged simply by placing it on the charging pad, the convenience of the user can be improved.

  FIG. 1 is an explanatory diagram showing a mode in which a portable information device is charged with a charging pad.

  According to FIG. 1, a smartphone 1 as a portable information device is merely placed on a charging pad 2 as a charger. At this time, the power transmission side coil embedded in the upper surface of the charging pad 2 and the power reception side coil embedded in the back surface of the smartphone 1 are close to each other. An electromotive force is generated in the coil of the smartphone 1 through the magnetic flux generated by passing a current through the coil of the charging pad 2. And the electromotive force which generate | occur | produced in the coil inside the smart phone 1 is electrically fed to a battery.

  As another technique, in particular, NFC (Near Field Communication) has been generally installed in portable information devices such as smartphones in recent years. NFC is an international standard for short-distance communication, and realizes data communication that only “holds” instantaneously at a distance of about 10 cm. Specifically, NFC has a card emulation function and a reader / writer function, and can transmit and receive a small amount of information on both the reader side and the writer side. When performing NFC communication, the user needs to actively touch and hold the smart phone on the card emulation side with respect to the specific device on the reader side. NFC mounted on a smartphone can be used for various purposes (see, for example, Non-Patent Documents 3, 4, and 5).

It is a functional block diagram of the portable information device and charger in this invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 2 is an external configuration diagram of the portable information device and the charger.

  According to FIG. 2, in addition to the power receiving unit (coil) 11 of FIG. 1, a wireless tag reader 12 is also embedded on the back surface of the portable information device 1 such as a smartphone. In addition to the power transmission unit (coil) 21 in FIG. 1, a wireless tag 22 is also attached to the upper surface of the charger 2 such as a charging pad. For simplicity, the wireless charging tag 2 may be attached to the existing charging pad 2. The power receiving unit 11 and the power transmitting unit 21 preferably have a wireless charging function based on the Qi standard. The wireless tag reader 12 and the wireless tag 22 are preferably based on the NFC standard. Functions based on these standards will be generally installed in smartphones in the future.

  According to FIG. 2, a frame line for installing the smartphone 1 is also drawn on the charging pad 2. The user places the smart phone 1 in the installation frame, so that the radio tag reader 12 of the smart phone 1 and the radio tag 22 of the charging pad 2 are positioned close to each other. According to the Qi standard, the smartphone 1 can be charged at any position on the charging pad 2. However, according to the NFC standard, the distance between the wireless tag and the wireless tag reader needs to be as close as possible. Therefore, a frame line is drawn.

  In the following description, it is assumed that the portable information device 1 is a smartphone and the charger 2 is a charging pad.

  FIG. 3 is a system configuration diagram according to the present invention.

  According to FIG. 3, the smartphone 1 can connect a wireless link between the access point 4 of the wireless LAN, the base station 4 of 3G or LTE (Long Term Evolution), and the Bluetooth device 4. In particular, the access point 4 is connected to an access network (provider network) via a LAN. The access point 4 and the base station 4 are provided as an edge of the access network. These access networks are interconnected to the Internet, and the content server 3 is connected to the Internet. With such a system configuration, the smartphone 1 can receive content from the content server 3.

  According to FIG. 3, the content server 3 is connected to the Internet as a wide area network, but may be connected to a LAN to which the access point 4 is connected. For example, the smartphone 1 being charged with the charging pad 2 in the store can be connected to the content server 3 via the in-store LAN via the access point 4 in the store.

  Further, the smartphone 1 can measure the current position by receiving radio waves from a GPS (Global Positioning System) satellite 5. Further, by receiving radio waves from a plurality of base stations 4 in the mobile phone network, positioning can be performed based on a plurality of base station positioning methods. By such positioning, it is possible to specify a store or the like where the user who owns the smartphone 1 stays.

FIG. 4 is a functional configuration diagram of the portable information device according to the present invention.
FIG. 5 is a sequence diagram in the present invention.

  According to FIG. 3, the portable information device 1 includes at least a power receiving unit 11, a wireless tag reader 12, and a battery 13 as hardware. In addition, as an option, a touch panel display 14, a communication interface 15, a positioning unit 16, and a front camera 17 are provided.

  The touch panel display 14 is generally mounted on a smartphone and serves as an interface for the user. By reproducing the content by the display function, the user can browse the content. Moreover, the specific information (for example, coupon number mentioned later) which a user has can be acquired with a touch panel function.

  The communication interface 15 is a wireless communication unit that communicates with a wireless LAN (WiFi) access point, a Bluetooth information device, a 3G (3rd Generation), or a WiMAX (Worldwide Interoperability for Microwave Access) base station. The smartphone 1 can connect to an access network via the access point 4 or the base station 4 and communicate with various servers connected to the Internet via the access network.

  The positioning unit 16 measures the current position, and may be based on a GPS positioning method, for example. Latitude and longitude can be measured by positioning radio waves. Further, the positioning unit 16 may be integrated with the communication interface 15 and based on the multiple base station positioning method. By receiving radio waves from a plurality of base stations, a rough current position can be determined.

  The front camera 17 is disposed on the touch panel display 14 side of the smartphone, and can capture a user who views the touch panel display. The front camera 17 is also generally mounted on a smartphone.

  According to FIG. 3, the portable information device (smartphone) 1 includes at least a charge detection unit 101 and a wireless tag reader activation control unit 102. In addition, as an option, a link connection control unit 103, a connection connection control unit 104, a content acquisition / playback unit 105, a remaining capacity detection unit 106, a face recognition unit 107, and a service information acquisition unit 108 are provided. These functional components are realized by executing a program that causes a computer mounted on the portable information device to function. In particular, it can be realized as an “app” installed on a smartphone. Moreover, the flow of processing of these functional components can be understood as a charging method for the portable information device.

[Charge detection unit 101]
The charging detection unit 101 detects the start of charging in which an electromotive force is generated in the coil of the power receiving unit 11 when approaching the charger 2 (see S1 in FIG. 5). The charging start detection information is output to the wireless tag reader activation control unit 102.

  Here, when the charge detection unit 101 detects that an electromotive force is generated in the power reception unit 11, it is also preferable to temporarily disconnect (for example, about 5 seconds) the electromagnetic induction charging circuit. As described later, it is possible to prevent the charging electromagnetic wave from interfering with the radio wave for the wireless tag when the wireless tag reader 12 of the smartphone 1 reads the wireless tag 22 of the charging pad 2 of the charger 2.

[Wireless tag reader activation control unit 102]
When the charging start of the power receiving unit 11 is detected, the wireless tag reader activation control unit 102 activates the wireless tag reader 12 (see S2 in FIG. 5). Then, the wireless tag reader 12 reads the tag information of the wireless tag on the charging pad 2 (see S3 in FIG. 5). The read tag information is output from the wireless tag reader 12.

[Link connection control unit 103]
It is assumed that the wireless tag 22 of the charging pad 2 includes link connection information to the access point or base station of the access network as tag information. For example, in the case of a wireless LAN access point, the link connection information may be an SSID (Service Set Identifier). The SSID is an identifier of an access point, and is set with up to 32 alphanumeric characters.

  Then, the link connection control unit 103 starts link connection of the link connection information read by the wireless tag reader 12 to the access point or base station (see S5 in FIG. 5). For example, the SSID of the access point 4 arranged in the store is described in the wireless tag 22. As a result, the smartphone 1 being charged can be connected to the access point 4 of the store. The link connection includes not only the SSID but also user ID and password authentication, and password encryption type settings such as TKIP (Temporal Key Integrity Protocol) or AES (Advanced Encryption Standard). It is preferable that the setting information is automatically transmitted as much as possible by the application of the smartphone 1 without causing the user to perform an input operation.

  Further, the link connection control unit 103 has a timer for measuring a predetermined connectable time. This timer is like an access right with a time limit. A timer is started when the link to the access network is connected, and then the link with the access network is disconnected when the timer times out. The timer may be about 2 hours, for example.

[Remaining capacity detection unit 106]
The remaining capacity detection unit 106 detects the remaining charge of the battery mounted on the portable information device. This remaining charge is output to the link connection control unit 103.

  Here, the link connection control unit 103 does not start the link connection of the access network when the remaining charge of the battery is equal to or less than the predetermined threshold value. This is because when the remaining charge of the battery is extremely small, power is consumed for connection to the network. For this reason, link connection is started only when the remaining charge is greater than a predetermined threshold.

[Connection Connection Control Unit 104]
It is assumed that the wireless tag 22 of the charging pad 2 includes connection information for the server as tag information. The connection information may be a homepage URL (Uniform Resource Locator), for example.

  Here, the connection connection control unit 104 starts connection connection to the server of the connection connection information read by the wireless tag reader 12 via the access network (see S6 in FIG. 5). The connection means establishment of a protocol between a client and a server connected by TCP / IP, for example. For example, the URL of the store homepage is described in the wireless tag 22. Thereby, the user can browse the homepage of the store for the smartphone 1 being charged.

[Content acquisition / playback unit 105]
The content acquisition / playback unit 105 transmits a content acquisition request to the content server 3 (see S6 in FIG. 5). The content acquisition request is, for example, an HTTP (Hyper Text Transfer Protocol) GET request, and is transmitted toward the address of the content server 3 to which the connection is made. The content acquisition / playback unit 105 receives the content from the content server 3 and plays back the content on the user interface. For example, the advertising content of the store can be distributed to the smartphone being charged with the charging pad 2 arranged in the store. For a store, the electricity bill for charging can be considered as part of the advertising fee.

  The content acquisition / playback unit 105 can also transmit the current position measured by the positioning unit 16 to the content server 3. That is, the measured current position is included in the content acquisition request. As a result, the content server searches for the content based on the current position and returns the content to the smartphone 1. The “content based on the current position” is not necessarily limited to the position information, but may be any content that the content server should deliver to the smartphone 1 existing at the position.

<Relationship Between Link Connection Control Unit 103 and Connection Connection Control Unit 104>
The smartphone 1 connects a link with the content server 3 via the access network after connecting the link with the access point 4 or the base station 4. Conventionally, in order to establish a wireless link such as a wireless LAN, the smartphone 1 requires selection of an SSID to be connected to the access point. Therefore, the link connection control unit 103 described above can read the SSID for connecting to the access point 4 from the wireless tag reader 12 of the charging pad 2.

  On the other hand, in recent years, there is a standard technology called “HotSpot2.0” (WBA (Wireless Broadband Alliance)) that performs authentication of a mobile phone network in a public wireless LAN. According to this technology, in the case of a smartphone that can be connected to a mobile phone network such as 3G or LTE, a link can be automatically connected to the access point 4 of the wireless LAN without reading the SSID.

  When this technique is applied to the present invention, the connection information is read by the wireless tag reader 12. The link connection control unit 103 does not particularly function, and then the smartphone 1 establishes a wireless link with the access point 4 using, for example, predetermined storage information or HotSpot2.0. Thereafter, the connection connection control unit 104 can establish a connection with the content server 3 based on the connection information and receive the content.

[Face recognition unit 107]
The face recognition unit 107 uses the front camera 17 to recognize the face of the user facing the display. For example, in the case of Android (registered trademark), a face of a still image can be recognized by using a class called “android.media.FaceDetector”. Information indicating that the face has been recognized is output to the content acquisition / playback unit 105.

Here, the content acquisition / playback unit 105 plays back the content received from the content server 3 on the display when the face recognition unit 107 recognizes the face. Thus, the content can be reproduced only when the user is viewing the display while the smartphone 1 is being charged. Here, the content acquisition / playback unit 105 plays back the content in the following two patterns.
(1) When a face is detected by the face recognition unit 107, the content acquisition / playback unit 105 transmits a content acquisition request to the content server 3. Thereafter, the content received from the content server 3 is reproduced on the display.
(2) The content acquisition / playback unit 105 has already received and stored the content to be played back from the content server 3. In addition, when the face is detected by the face recognition unit 107, the content acquisition / playback unit 105 plays back the content stored in advance on the display.

[Service Information Acquisition Unit 108]
The service information acquisition unit 108 acquires service information for the user. The service information acquired from the user is, for example, a coupon number when a product is purchased at the store. The coupon number may be a number manually input by the user or a number obtained by reading a QR (Quick Response) code.

  The service information acquisition unit 108 may store predetermined service information recorded in advance on the smartphone, for example, electronic money shopping history, station entrance / exit information, and the like. This service information is output to the content acquisition / playback unit 105. The content acquisition / playback unit 105 transmits a content acquisition request including the predetermined service information to the content server 3. As a result, the content server 3 searches for content according to the predetermined service information included in the content acquisition request, and returns the content to the smartphone 1.

  At this time, the content acquisition / playback unit 105 transmits a content acquisition request including the service information (for example, a coupon number) to the content server 3. As a result, the content server 3 searches for content based on the service information, and returns the content (for example, a coupon) to the smartphone 1. The user can receive provision of a new service by the coupon reproduced on the display of the smartphone 1. Note that the content acquisition / playback unit 105 can receive content based on a combination of service information and the current position by transmitting the current position together with the service information to the content server 3.

  FIG. 6 is a functional configuration diagram of the portable information device and the charger according to the present invention.

  According to FIG. 6, while the smart phone 1 carries the near field communication part 18, the charger 2 also carries the near field communication part 24, and it can communicate mutually. The short-range communication unit may be based on, for example, the Bluetooth (registered trademark) standard. Bluetooth is a short-range wireless communication system of about several meters, and can communicate radio waves in the 2.45 GHz band at 24 Mbps. In addition, pairing between devices in Bluetooth is automatically exchanged when the wireless tag is brought close by NFC. This enables short-range communication based on Bluetooth without the user performing pairing operation himself. The smartphone 1 transmits content to be displayed on its display from the short-range communication unit 18.

  Moreover, according to FIG. 6, the charger 2 is equipped with the touch panel display 25 with the charging pad. The charger 2 displays the content received by the short-range communication unit 24 from the smartphone 1 on the touch panel display 25. The user can place the smartphone 1 on the charging pad for charging, and can also browse the content on the touch panel display 25 of the charger 2. Of course, information operated on the touch panel by the user is also transmitted from the short-range communication unit 24 of the charger 2 to the short-range communication unit 18 of the smartphone 1.

  Although FIG. 6 illustrates an example in which the smartphone 1 and the charger 2 communicate at a short distance via Bluetooth, of course, HDMI (High-Definition Multimedia Interface) (registered trademark), USB ( It may be connected via a Universal Serial Bus) cable. Further, the touch panel display is not necessarily configured integrally with the charger 2 and may be a single touch panel display installed outside.

  As described above in detail, according to the portable information device, system, program, and method of the present invention, the portable information device provides various services during charging by reading predetermined information from the charger. be able to.
