Description

  The present invention relates to a method for controlling a wireless power receiving apparatus that receives power wirelessly.

  Rechargeable secondary batteries are often used for batteries of electronic devices as batteries of electronic devices have been reduced in size, increased in output, and increased in capacity.

  As a means for charging a secondary battery of an electronic device, a device using a dedicated charger, or a device that receives power supply from an external device in a wired manner and charges in an electronic device main body has been generally used. Wireless power feeding that receives power supplied by electromagnetic waves without being connected by an electric device and charges the electronic device main body has become common.

  In wireless power feeding, electromagnetic waves radiated from the antenna of the power transmission device on the power transmission side are received by the antenna of the power reception device on the power reception side, and power is transmitted and received. And so as not to radiate electromagnetic waves in an uncontrolled state, by acquiring the mutual power transmission / reception information between the power transmission device and the power reception device by communication, by performing power transmission and power reception with the power determined by the communication, A method of controlling power transmission / reception without hindrance is common.

  Some control communication for wireless power feeding uses out-of-band communication different from the frequency at which wireless power is transmitted and received. For example, a wireless power feeding method has been proposed in which 6.78 MHz or 13.56 MHz in the HF band is used as a carrier frequency for wireless power, and the control communication uses a carrier frequency centered on 2.45 GHz in the UHF band. Control communication of a wireless power feeding method in which the frequency of power and the frequency of control communication are different is generally called an out-of-band communication method.

  As an out-of-band communication method, Bluetooth (registered trademark) Low Energy can be used as one of the wireless standards. Bluetooth (registered trademark) Low Energy (hereinafter abbreviated as BLE) is a device in which the role of the peripheral transmits an advertise packet, and the device in the role of the central device that has received the advertise packet requests a connection. After the connection is established, data is transmitted / received.

  Since the BLE peripheral device can be connected to only one BLE central device, if the power receiving device is a BLE peripheral device, the power receiving device is connected to the power transmitting device, which is the BLE central device, by BLE, and performs control communication for wireless power feeding. It will be.

  When a power receiving device that is a BLE peripheral device is connected to a power transmitting device that is a BLE central device and performs control communication for wireless power feeding, BLE connection with other BLE central devices is not possible.

  The power receiving device, which is a BLE peripheral device, not only communicates with the power transmission device, but also may be connected to other wireless communication devices that are BLE central devices to perform data communication with BLE. In that case, there was a problem that it was not possible to connect to the power transmission device as the BLE central device, and wireless power feeding could not be started.

  A power receiving device, which is a BLE peripheral device, is connected to another wireless communication device, which is a BLE central device, and exchanges pairing information by BLE data communication using it as a trigger to perform wireless communication using other wireless communication standards. Problems can occur even in over scenarios.

  When the battery capacity of the power receiving apparatus for performing wireless communication in other wireless communication standards is insufficient, the power receiving apparatus is connected to the other apparatus wireless communication apparatus in BLE normally. Therefore, the subsequent handover and subsequent operations (services) are not started, and the user is confused.

  For this reason, in selecting a BLE central device that is a connection partner of a power receiving device that is a BLE peripheral device, in particular, a power transmission device and another wireless communication device, it is simply effective without troublesome operations such as switching the connection partner by the user. There is a need for a method of selecting a connection partner that can perform a service.

  Patent Document 1 proposes a power transmission device that detects the approach of the portable electronic device on the power transmission device side and performs power transmission in order to charge the power storage module of the portable electronic device in response to the detection of the approach. .

  US Pat. No. 6,053,836 discloses an electromagnetic interference between a device including a transmit antenna configured to transmit wireless power in a near field between the transmit antenna and an antenna of another electronic device disposed on the device. Have been proposed to enable communication links for other electronic devices.

  In S110, the power receiving apparatus 201 determines whether there is a connection request from the BLE central apparatus to the RX communication unit C231 and the communication link is established. In S110, if the power receiving apparatus 201 has established a connection with the BLE central apparatus, the process proceeds to S111, communicates with the BLE central apparatus, and proceeds to S112. In S110, the power receiving apparatus 201 returns to S101 if there is no connection request from the BLE central apparatus to the RX communication unit C231 and no communication link is established.

  In step S112, the power receiving apparatus 201 determines whether the communication link connection with the BLE central apparatus in the RX communication unit C231 has been completed. In S112, if the power receiving apparatus 201 has completed the communication link connection with the BLE central apparatus, the process returns to S101.

  The flowchart of FIG. 14 will be described. The flowchart in FIG. 14 starts when the RX battery 203 of the power receiving apparatus 201 is inserted.

  In S101, the power receiving apparatus 201 determines whether the voltage of the RX battery 203 is equal to or higher than the first threshold value. If the power receiving apparatus 201 determines in step S101 that the voltage of the RX battery 203 is equal to or higher than the first threshold value, the process proceeds to step S102. In step S102, the power receiving apparatus 201 determines whether the voltage of the RX battery 203 is equal to or higher than the second threshold value. To do. The first threshold value of the RX battery 203 is a value at which the operation of at least the RX control unit 202 and the RX communication unit C231 of the power receiving apparatus 201 is normally guaranteed. The second threshold value of the RX battery 203 is a value that is higher than the first threshold value and that ensures normal operation of some or all functions of the power receiving apparatus 201.

  In S102, when the power receiving apparatus 201 determines that the voltage of the RX battery 203 is equal to or higher than the second threshold, the process proceeds to S103, and in S103, the power receiving apparatus 201 determines whether there is a stimulus input. The stimulus input in S103 is, for example, a detection signal of the RX voltage detection circuit A214, power input from the RX connector 260, a detection signal of the RX detection circuit B215, and the like.

  In addition, the determination of the stimulus input in S103 determines that there is a stimulus input when the stimulus input continues for a certain period of time, and prevents the stimulus input when it does not continue for a certain period of time, in order to prevent a single noise mask or erroneous operation. You may judge. If the power receiving apparatus 201 determines that there is no stimulus input in S103, the process proceeds to S104, and in S104, the advertisement packet transmitted from the RX communication unit C231 is set as the first advertisement packet. In step S109, the power receiving apparatus 201 transmits the set first advertisement packet from the RX communication unit C231 and returns to step S101.

In step S113, the power receiving apparatus 201 determines whether there is a standby power input from another apparatus. The standby power input in S113 is, for example, electromagnetic waves received by the RX power receiving antenna A213, power input from the RX connector 260, or the like. In S113, even if the voltage of the RX battery 203 of the power receiving apparatus 201 is not equal to or higher than the first threshold, the RX control unit 202 is operated by the standby power input, and the determination in S113 can be made.

  If the power receiving apparatus 201 determines in step S113 that there is no standby power input from another apparatus, the process proceeds to step S114, stops transmitting the advertisement packet transmitted from the RX communication unit C231 in step S114, and ends the flowchart of FIG.

In S <b> 105, the RX control unit 202 acquires the status of the RX communication unit B <b> 221, receives electromagnetic waves for data reading and data writing from the non-contact IC reader, and performs communication with the RX communication unit B <b> 221 of the power receiving apparatus 201. It can be judged that In S105, whether power is supplied from another device via the RX connector 260 can be determined by data communication between the RX control unit 202 and another device, the voltage of the RX constant voltage circuit A281, and the like.

  If the power receiving apparatus 201 determines in S105 that communication with the RX communication unit B221 has been performed or that power is being supplied from another apparatus via the RX connector 260, the process proceeds to S104, and the RX communication unit C231 transmits the power. The advertisement packet is set as the first advertisement packet. In step S109, the power receiving apparatus 201 transmits the set first advertisement packet from the RX communication unit C231 and returns to step S101.

  If it is determined in S105 that the power receiving apparatus 201 is not communicating with the RX communication unit B221 or that power is not supplied from another apparatus via the RX connector 260, the process proceeds to S106. In S106, the RX battery It is determined whether or not the electromagnetic wave from the power transmission device 101 disappears once the charging of 203 is completed.

  In S <b> 106, the RX control unit 202 can determine whether or not the RX power receiving antenna A <b> 213 receives the electromagnetic wave from the power transmission device 101 based on the detection signal of the RX voltage detection circuit A <b> 214. In S106, if the electromagnetic wave from the power transmission apparatus 101 is continuing after the RX battery 203 is completely charged, that is, if the electromagnetic wave is not reset, the process proceeds to S104. In S106, once the RX battery 203 is completely charged, the electromagnetic wave from the power transmission apparatus 101 is once lost. That is, if the electromagnetic wave is reset, the process proceeds to S107. In S107, the communication link with another apparatus using the RX communication unit C231. Exit.

  Then, in S108, the advertisement packet transmitted from the RX communication unit B221 is set as the second advertisement packet. In step S109, the power receiving apparatus 201 transmits the set second advertisement packet from the RX communication unit C231.

  In S110, the power receiving apparatus 201 determines whether there is a connection request from the BLE central apparatus to the RX communication unit C231 and the communication link is established. In S110, if the power receiving apparatus 201 has established a connection with the BLE central apparatus, the process proceeds to S111, communicates with the BLE central apparatus, and proceeds to S112. In S110, the power receiving apparatus 201 returns to S101 if there is no connection request from the BLE central apparatus to the RX communication unit C231 and no communication link is established.

  In step S112, the power receiving apparatus 201 determines whether the communication link connection with the BLE central apparatus in the RX communication unit C231 has been completed. In S112, if the power receiving apparatus 201 has completed the communication link connection with the BLE central apparatus, the process returns to S101. In S112, if the communication link connection with the BLE central apparatus is not completed, the power receiving apparatus 201 returns to S111 and performs communication with the BLE central apparatus.

  In S101, the power receiving apparatus 201 determines whether the voltage of the RX battery 203 is equal to or higher than the first threshold value. If the power receiving apparatus 201 determines in step S101 that the voltage of the RX battery 203 is equal to or higher than the first threshold value, the process proceeds to step S103. In step S103, the power receiving apparatus 201 determines whether there is a stimulus input. The stimulus input in S103 is, for example, a detection signal of the RX voltage detection circuit A214, power input from the RX connector 260, a detection signal of the RX detection circuit B215, and the like.

  In addition, the determination of the stimulus input in S103 determines that there is a stimulus input when the stimulus input continues for a certain period of time, and prevents the stimulus input when it does not continue for a certain period of time, in order to prevent a single noise mask or erroneous operation. You may judge. The first threshold value of the RX battery 203 is a value at which the operation of at least the RX control unit 202 and the RX communication unit C231 of the power receiving apparatus 201 is normally guaranteed.

  If the power receiving apparatus 201 determines that there is no stimulus input in step S103, the process proceeds to step S124. In step S124, the GATT server database that stores the service and characteristic of the RX communication unit C231 is set to the first service setting.

It can be judged that In S105, whether power is supplied from another device via the RX connector 260 can be determined by data communication between the RX control unit 202 and another device, the voltage of the RX constant voltage circuit A281, and the like.

  If the power receiving apparatus 201 determines in S105 that communication with the RX communication unit B221 has been performed or that power is being supplied from another apparatus via the RX connector 260, the process proceeds to S124, and the service of the RX communication unit C231 is The GATT server database that stores Characteristic is set to the first service setting. In step S109, the power receiving apparatus 201 transmits a fourth advertisement packet from the RX communication unit C231 and returns to step S101.

  If it is determined in S105 that the power receiving apparatus 201 is not communicating with the RX communication unit B221 or that power is not supplied from another apparatus via the RX connector 260, the process proceeds to S106. In S106, the RX battery It is determined whether or not the electromagnetic wave from the power transmission device 101 disappears once the charging of 203 is completed. In S <b> 106, the RX control unit 202 can determine whether or not the RX power receiving antenna A <b> 213 receives the electromagnetic wave from the power transmission device 101 based on the detection signal of the RX voltage detection circuit A <b> 214.

  In S106, if the electromagnetic wave from the power transmission apparatus 101 is continuing after the RX battery 203 is completely charged, that is, if the electromagnetic wave is not reset, the process proceeds to S104. In S106, once the RX battery 203 is completely charged, the electromagnetic wave from the power transmission apparatus 101 is once lost. That is, if the electromagnetic wave is reset, the process proceeds to S107. In S107, the communication link with another apparatus using the RX communication unit C231. Exit.

  In step S128, the GATT server database storing the service and the charac- teristic of the RX communication unit C231 is set to the second service setting. In step S109, the power receiving apparatus 201 transmits a fourth advertisement packet from the RX communication unit C231.

  In S110, the power receiving apparatus 201 determines whether there is a connection request from the BLE central apparatus to the RX communication unit C231 and the communication link is established. In S110, if the power receiving apparatus 201 has established a connection with the BLE central apparatus, the process proceeds to S111, communicates with the BLE central apparatus, and proceeds to S112. In S110, the power receiving apparatus 201 returns to S101 if there is no connection request from the BLE central apparatus to the RX communication unit C231 and no communication link is established.

  In step S112, the power receiving apparatus 201 determines whether the communication link connection with the BLE central apparatus in the RX communication unit C231 has been completed. In S112, if the power receiving apparatus 201 has completed the communication link connection with the BLE central apparatus, the process returns to S101. In S112, if the communication link connection with the BLE central apparatus is not completed, the power receiving apparatus 201 returns to S111 and performs communication with the BLE central apparatus.

In the first embodiment, the method for changing the advertisement packet transmitted from the power receiving device according to the change in the battery voltage of the power receiving device has been described. In the second embodiment, a method has been described in which an advertisement packet transmitted from a power receiving device is changed by an electromagnetic wave of wireless power received by the power receiving device from the power transmitting device. In the third embodiment, the method of changing the advertisement packet transmitted from the power receiving device based on the change in the battery voltage of the power receiving device and the electromagnetic wave of the wireless power received by the power receiving device from the power transmitting device has been described. In the fourth embodiment, the advertisement packet transmitted from the power receiving device is not changed due to a change in the battery voltage of the power receiving device. The method of changing the service of the GATT server database that stores the service and the charac- teristic of the power receiving apparatus has been described.

In the sixth embodiment, the advertisement packet transmitted from the power receiving device is not changed by the change in the battery voltage of the power receiving device and the electromagnetic waves of the wireless power received by the power receiving device from the power transmitting device. A method of changing the service of the GATT server database that stores the service and the charac- teristic of the power receiving apparatus will be described.
Note that FIG. 27 best represents the sixth embodiment, and therefore the sixth embodiment will be described with reference to FIG.

  A block diagram showing a configuration example of the power transmission device 101, the power reception device 201, and the wireless communication device 301 according to the present embodiment is the same as FIGS. 5, 6, and 7 described in the first embodiment, and thus description thereof is omitted. To do. In addition, the data example of the advertisement packet transmitted from the power receiving apparatus 201 according to the present embodiment is the same as that in FIG. 22, and the GATT server database example that stores the Service and Characteristic of the power receiving apparatus 201 is the same as that in FIG. To do. The flowchart of FIG. 27 will be described. The flowchart in FIG. 27 starts when the RX battery 203 of the power receiving apparatus 201 is inserted.

  In S101, the power receiving apparatus 201 determines whether the voltage of the RX battery 203 is equal to or higher than the first threshold value. If the power receiving apparatus 201 determines in step S101 that the voltage of the RX battery 203 is equal to or higher than the first threshold value, the process proceeds to step S102. In step S102, the power receiving apparatus 201 determines whether the voltage of the RX battery 203 is equal to or higher than the second threshold value. To do. The first threshold value of the RX battery 203 is a value at which the operation of at least the RX control unit 202 and the RX communication unit C231 of the power receiving apparatus 201 is normally guaranteed. The second threshold value of the RX battery 203 is a value that is higher than the first threshold value and that ensures normal operation of some or all functions of the power receiving apparatus 201.

  In S102, when the power receiving apparatus 201 determines that the voltage of the RX battery 203 is equal to or higher than the second threshold, the process proceeds to S103, and in S103, the power receiving apparatus 201 determines whether there is a stimulus input. The stimulus input in S103 is, for example, a detection signal of the RX voltage detection circuit A214, power input from the RX connector 260, a detection signal of the RX detection circuit B215, and the like.

  In addition, the determination of the stimulus input in S103 determines that there is a stimulus input when the stimulus input continues for a certain period of time, and prevents the stimulus input when it does not continue for a certain period of time, in order to prevent a single noise mask or erroneous operation. You may judge. If the power receiving apparatus 201 determines that there is no stimulus input in step S103, the process proceeds to step S124. In step S124, the GATT server database that stores the service and characteristic of the RX communication unit C231 is set to the first service setting.

  In step S109, the power receiving apparatus 201 transmits a fourth advertisement packet from the RX communication unit C231 and returns to step S101. If the power receiving apparatus 201 determines in step S101 that the voltage of the RX battery 203 is not equal to or higher than the first threshold value, the process proceeds to step S113. In step S113, the power receiving apparatus 201 determines whether there is a standby power input from another apparatus. The standby power input in S113 is, for example, electromagnetic waves received by the RX power receiving antenna A213, power input from the RX connector 260, or the like.

  In S113, even if the voltage of the RX battery 203 of the power receiving apparatus 201 is not equal to or higher than the first threshold, the RX control unit 202 is operated by the standby power input, and the determination in S113 can be made. If the power receiving apparatus 201 determines in step S113 that there is no standby power input from another apparatus, the process proceeds to step S114, stops transmitting the advertisement packet transmitted from the RX communication unit C231 in step S114, and ends the flowchart of FIG. If the power receiving apparatus 201 determines in step S113 that there is no standby power input from another apparatus, the process proceeds to step S105. The process of S105 will be described later. If the power receiving apparatus 201 determines in step S102 that the voltage of the RX battery 203 is not equal to or higher than the second threshold value, the process proceeds to step S105. The process of S105 will be described later.

  If the power receiving apparatus 201 determines in S103 that there is a stimulus input, the process proceeds to S105. In S105, it is determined whether communication with the RX communication unit B221 has been performed or power is being supplied from another apparatus via the RX connector 260. to decide. In S <b> 105, the RX control unit 202 acquires the status of the RX communication unit B <b> 221, receives electromagnetic waves for data reading and data writing from the non-contact IC reader, and performs communication with the RX communication unit B <b> 221 of the power receiving apparatus 201. It can be judged that

In S105, whether power is supplied from another device via the RX connector 260 can be determined by data communication between the RX control unit 202 and another device, the voltage of the RX constant voltage circuit A281, and the like. If the power receiving apparatus 201 determines in S105 that communication with the RX communication unit B221 has been performed or that power is being supplied from another apparatus via the RX connector 260, the process proceeds to S124, and the service of the RX communication unit C231 is The GATT server database that stores Characteristic is set to the first service setting.
In step S109, the power receiving apparatus 201 transmits a fourth advertisement packet from the RX communication unit C231 and returns to step S101.

  If it is determined in S105 that the power receiving apparatus 201 is not communicating with the RX communication unit B221 or that power is not supplied from another apparatus via the RX connector 260, the process proceeds to S106. In S106, the RX battery It is determined whether or not the electromagnetic wave from the power transmission device 101 disappears once the charging of 203 is completed.

In S <b> 106, the RX control unit 202 can determine whether or not the RX power receiving antenna A <b> 213 receives the electromagnetic wave from the power transmission device 101 based on the detection signal of the RX voltage detection circuit A <b> 214.
In S106, if the electromagnetic wave from the power transmission apparatus 101 is continuing after the RX battery 203 is completely charged, that is, if the electromagnetic wave is not reset, the process proceeds to S104.

  In S106, once the RX battery 203 is completely charged, the electromagnetic wave from the power transmission apparatus 101 is once lost. That is, if the electromagnetic wave is reset, the process proceeds to S107. In S107, the communication link with another apparatus using the RX communication unit C231. Exit.

  In step S128, the GATT server database storing the service and the charac- teristic of the RX communication unit C231 is set to the second service setting. In step S109, the power receiving apparatus 201 transmits a fourth advertisement packet from the RX communication unit C231.

  In S110, the power receiving apparatus 201 determines whether there is a connection request from the BLE central apparatus to the RX communication unit C231 and the communication link is established. In S110, if the power receiving apparatus 201 has established a connection with the BLE central apparatus, the process proceeds to S111, communicates with the BLE central apparatus, and proceeds to S112. In S110, the power receiving apparatus 201 returns to S101 if there is no connection request from the BLE central apparatus to the RX communication unit C231 and no communication link is established.

  In step S112, the power receiving apparatus 201 determines whether the communication link connection with the BLE central apparatus in the RX communication unit C231 has been completed. In S112, if the power receiving apparatus 201 has completed the communication link connection with the BLE central apparatus, the process returns to S101. In S112, if the communication link connection with the BLE central apparatus is not completed, the power receiving apparatus 201 returns to S111 and performs communication with the BLE central apparatus.

  Since the detailed description of the advertisement packet and the GATT server database has been described in the fourth embodiment, the description in the present embodiment is omitted. The flowchart of FIG. 27 has been described above.

In the seventh embodiment, as another embodiment of the fourth to sixth embodiments, the method of changing the Service VALUE in the GATT server database storing the Service and Characteristic of the power receiving apparatus has been described.

  In the eighth embodiment, as an embodiment used in combination with the first to seventh embodiments, the power receiving device receives the electromagnetic waves of the wireless power that the power receiving device receives from the power transmitting device due to the change in the battery voltage of the power receiving device. A method for reducing the generated and available power is described.

  FIG. 29 is a block diagram illustrating a configuration example of the power receiving device 401 according to the present embodiment. The power receiving device 401 is a device that can receive power wirelessly from the power transmitting device. Since the same number is attached | subjected to the same block as the power receiving apparatus 201 demonstrated in 1st Embodiment, description of a function is abbreviate | omitted.

  In the block diagram used in the description of the present embodiment, power supply connections to blocks that are not necessary for the description of the present embodiment, and description of input and output capacitors of each block are omitted. Also, detailed descriptions of blocks and operations that are not necessary for the description of the present embodiment are omitted.

  The RX voltage detection circuit C271 is a voltage detection circuit that detects the voltage of the RX battery 203, and does not output a detection signal when it is less than the voltage detection threshold Vth2, and outputs a detection signal when it is equal to or higher than the voltage detection threshold Vth2.

  Note that the value of the voltage detection threshold value Vth2 of the RX voltage detection circuit C271 may be the same as the first threshold value or a value greater than that.

  The RXANT load circuit 272 is a load circuit connected between the voltage generated in the RX power receiving antenna A 213 and GND, and the load can be controlled ON / OFF by the detection signal of the RX voltage detection circuit C 271 and the RX control unit 202. .

  The RXANT load circuit 272 is always ON when the detection signal of the RX voltage detection circuit C271 and the control signal of the RX control unit 202 are absent, and is OFF when the detection signal of the RX voltage detection circuit C271 and the control signal of the RX control unit 202 are present. Assume that the load is ON.

  The case where the RXANT load circuit 272 functions in the present embodiment is the case of the following characteristic steps in the operation sequence diagrams described in the first to seventh embodiments.

  S450, S2050: The electromagnetic wave received by the RX power receiving antenna A213 is activated as the operating power of the RX control unit 202 and the RX communication unit C231.

  The operation of step numbers S450 and S2050 is when the voltage of the RX battery 203 is not equal to or higher than the first threshold value, and the electromagnetic wave received by the RX power receiving antenna A213 is activated as the operating power of the RX control unit 202 and the RX communication unit C231. .

  For this reason, it is necessary that the power transmission device 101 and the power reception device 201 be arranged close to each other. After the power transmitting apparatus 101 and the power receiving apparatus 201 are in an arrangement state in which the power transmitting apparatus 101 and the power receiving apparatus 201 are close to each other, the power transmitting apparatus 101 and the power receiving apparatus 201 perform a wireless power supply service. 203 is charged.

  In many cases, the reason why wireless power cannot be received with high efficiency is the displacement of the TX power transmission antenna A113 of the power transmission apparatus 101 and the RX power reception antenna A213 of the power reception apparatus 201. It is necessary to guide the arrangement of the power transmission apparatus 101 and the power reception apparatus 201.

  In this embodiment, when the voltage of the RX battery 203 is not sufficient, for example, when the voltage of the RX voltage detection circuit C271 is less than the voltage detection threshold Vth2 or when the voltage of the RX battery 203 is less than the first threshold, the RXANT load circuit 272 is turned on. To.
