Fig. 1 illustrates an example of an interaction method and system of a power supply device and an adapter, to which the present disclosure may be applied, in the related art, as a charging technology in the mobile phone industry is continuously developed, a large number of fast charging technologies, such as PD, QC, and VOOC/super VOOC, emerge, referring to fig. 1, a power supply device in the related art detects a state of a battery 160 and communicates with a core processor 200 through an independent MCU130 and a data acquisition module 150, that is, detects attribute information of the battery 160, communicates with the adapter 110 according to the state of the battery 160, adjusts an output voltage and an output current of the adapter 110, controls a charge pump 121 to start a switching transistor, so that the transistor is turned on, to charge the battery 160, and is simultaneously completed in the independent MCU130 and the core processor 200 in a device to be charged when detecting the attribute information of the battery 160. Meanwhile, a charging controller 120 is configured, the charging controller is connected to the core processor 200 through a PMIC (Power Management Integrated Circuit) 170, the adapter 110 is connected to the core processor 200 through a universal asynchronous receiver/transmitter transmission line, a USB switch is used to control the switching of the lines, and a charging type determining module 124 is disposed in the charging controller 120 to determine whether the signal flow of the output signal of the adapter 110 needs to be started.

The power supply device in the related art adopts an independent MCU processor, so that the cost is high, the maintenance of independent firmware is needed, the cost is high, and the occupied area is large. The underlying hardware control logic of the original MCU processor is then integrated into the protocol physical layer. The capacity of detecting communication signals is stronger in a fast charging scheme based on a protocol physical layer, limit narrow-band burr signals can be detected, the burr signals can exist in the first few frames of signals of a certain old and irregular adapter when fast charging is started, the protocol physical layer recognizes the burr signals into normal fast charging signals, then data are collected, and finally fast charging communication is abnormal and disconnected, so that the burr signals need to be specially processed based on the protocol physical layer.

Based on this, the present application first proposes an interaction method, as shown in fig. 2, the method includes the following steps:

step S210, determining predetermined data information of multiple types of adapters, wherein the predetermined data information comprises target data information and error data information corresponding to the target data information;

step S220, receiving the reference data information sent by the adapter, and sending transmission data information according to the reference data information, so that the adapter sends the reference data information again according to the transmission data information and the preset data information;

step S230, verifying the adapter for multiple times according to the reference data information and the preset data information, and determining the target type of the adapter;

step S240, when the received reference data information is the same as the target data information corresponding to the adapter of the target type, establishing a direct charging communication link between the adapter and the power supply apparatus.

Compared with the prior art, the method and the device have the advantages that the error data information corresponding to the target data information is determined, the obtained reference data information, the target data information and the error data information are compared, the target type of the analyzer is obtained through multiple verification, the misjudgment of the type of the adapter caused by the burr signal at the fixed position can be prevented, meanwhile, after the verification is completed, the direct charging communication link between the adapter and the power supply device is established when the target data information is received, the establishment of the direct charging communication link after the burr signal disappears can be guaranteed, and the normal operation of the communication link is guaranteed.

The above steps will be described in detail below.

In step S210, predetermined data information of multiple types of adapters is determined, where the predetermined data information includes target data information and error data information corresponding to the target data information.

In an example embodiment of the present disclosure, target data information corresponding to a plurality of adapter types and error data information of the target data information under some predetermined errors may be first set, for example,

referring to fig. 3, a frame of communication between a protocol physical layer and an adapter is 18CLK (clock signal), the adapter sends 8-bit data to the protocol physical layer, the protocol physical layer processes 10 bits of data to reply to the adapter, and both the received and sent data of the protocol physical layer include a header, assuming that a command code sent by the adapter is a request fast fill code 0XA8, if there is a glitch signal 310 at this time, and the glitch signal 310 is sufficiently close to a first true bit signal, the protocol physical layer receives the glitch signal 310 to prepare for data sampling on a data pin, and then the coming true bit signal at this time finally results in that both the acquired bit signals are 0, and then 0XA 8b 10101000 sent by the adapter becomes a signal 0b 00010100-0X 14. Wherein 0XA8 can be used as the target data information, and 0X14 can be used as the error data information corresponding to the target data information.

The originally sent frame header is 101, which now becomes an erroneous 000 frame header, resulting in a fast charging failure, and then the processing time originally reserved for the digital signal processor is 5ms (8 th bit and 9 th bit time interval, CLK is completely controlled by the adapter), and now because a glitch signal is added, the processing time reserved for the digital signal processor is only 510us of the time interval between two bits. Special processing is therefore performed for glitch signals.

In the present exemplary embodiment, 0XA8 may be used as the target data information and 0X14 may be used as the error data information.

In step S220, the reference data information sent by the adapter is received, and the transmission data information is sent according to the reference data information, so that the adapter sends the reference data information again according to the transmission data information and the predetermined data information.

In an example embodiment of the present disclosure, the protocol physical layer may receive reference data information sent by the adapter, and restart the protocol physical layer to clear data in the protocol physical layer if the reference data information does not satisfy a preset condition. The preset time may be 25ms, 50ms, 10ms, or the like, or may be customized according to a user requirement, which is not specifically limited in this exemplary embodiment. The preset condition may be that the number of bytes of the received data is less than or equal to a preset number, where the preset number may be 18, 8, 10, or the like, and may also be customized according to user requirements, which is not specifically limited in this exemplary embodiment.

For example, referring to fig. 4, when the preset time is 25ms and the preset condition is that less than 18 clks (clock signals) are received, step S401 may be executed first to trigger the protocol physical layer interrupt, then step S402 may be executed to read the interrupt status register of the protocol physical layer, specifically, the interrupt status register is read in the interrupt processing function to determine which interrupt is triggered, the adaptor glitch is likely to cause the clk (clock signals) received by the protocol physical layer to be less than 18 clks, and then step S403 may be executed to determine whether the data is less than 18clk, for example, when the glitch interval is longer than 25ms, the protocol physical layer triggers, that is, only one glitch signal is received in 25 ms. When reference data information <18 clk (clock signal) interrupts is triggered, step S404, step S405, step S406, and step S407 may be performed; specifically, the data in the register received by the protocol physical layer may be discarded, and the specific method is to start the protocol physical layer first, then close the protocol physical layer, and finally start the protocol physical layer, so that the data in the register received by the protocol physical layer can be cleared, and the data in the next frame can be correctly received.

In an example embodiment of the present disclosure, the reference data information sent by the adapter is received, whether the reference data information is the same as the target data information or the error data information is determined, and if the reference data information is the same as the target data information or the error data information, the adapter type corresponding to the target data information is determined to be the reference type of the adapter.

Specifically, when the received reference data information is the same as the error data information, the generated transmission data information is shifted to the right by one bit, so that the adapter can send the reference data information to the protocol physical layer again. If the reference data information is the same as the target data information, the adapter may send the reference data information again according to the transmission data information.

In step S230, verifying the adapter for multiple times according to the reference data information and the predetermined data information, and determining a target type of the adapter;

in step S240, when the received reference data information is the same as the target data information corresponding to the adapter of the target type, a direct charging communication link between the adapter and the power supply apparatus is established.

In the present exemplary embodiment, when the received reference data information is the same as the error data information and the target data information a plurality of times, the adapter type corresponding to the target data information is set as the target type of the adapter.

In the present exemplary embodiment, if the data received by the protocol physical layer for the first time is 0X14, where 0X14 is error data information, and the corresponding target data information is 0XA8, the adapter reference type corresponding to 0XA8 is a VOOC2.0 adapter; at this time, the frame header of the transmission data information that the protocol physical layer can reply to the adapter may be a frame header corresponding to the VOOC2.0 adapter; then shifting the transmission data information by one bit to the right, so that the adapter sends the reference data information again to verify the type of the adapter; if the reference data information received for the second time is still 0X14, it can be determined that the target type of the adapter is the VOOC2.0 adapter or the adapter type can be verified again using the reference data information for the third time. The number of times of verification may be two, three, or more, and is not particularly limited in the present exemplary embodiment.

After determining the target type of the adapter, the reference data information is accepted again until the received reference data information is the same as the target data information, and a direct charging communication link between the power supply device and the adapter is established.

For example, referring to fig. 4, step S408 is first performed to read the receiving register of the phy, specifically, to read the data inside the receiving register of the phy, and then step S409, step S410 and step S411 are performed; specifically, it may be determined whether the data in the adapter is 0X14, and it should be noted that the normal data sent by the adapter before the fastchg _ allow is true cannot be 0X14, and the receipt of 0X14 indicates that the data in the adapter is affected by a glitch. Therefore, if the frame is not 0X14, the frame is handed to a normal data processing flow for processing, that is, the frame header of the frame data is considered not to be aligned, and the protocol physical layer needs to be reset again; in the case of 0X14, the fast _ allow is true, and a normal data processing flow is also required to process the frame data, that is, the frame header of the frame data is considered not to be aligned, and the protocol physical layer needs to be reset again.

When the received data is 0X14 and the fast _ allow is false, that is, the data of the glitch is received in the first few frames of data, it needs to be processed by a function of special processing 0X 14. The VOOC2.0 adapter can work in two modes, one is a real fast charging mode, the other is a powerbank mobile power mode, the reference type VOOC2.0 adapter of the adapter can be considered after receiving 0X14, and then step S412 can be executed to shift the data to be replied of the protocol physical layer by one bit to the right; and step S413, judging whether the quick charging mode is in; specifically, because the glitch affects the data that has received one bit more, in order to make the adapter receive the real frame header, the data to be recovered needs to be moved to the right by one bit, which has the essential effect that when the adapter sends the data of the last bit of 8 bits, the protocol physical layer starts to return the data (the protocol physical layer and the adapter operate the data signal of clk simultaneously), so the highest bit of 10 bits to be recovered has no effect.

When operating in the true fast charge mode, step S417 is executed, in which bit4 sets the setting of allowing fast charge, specifically, bit4 is set to 1 directly to indicate that fast charge is allowed (bit 3 is set to 1 under normal conditions to indicate that fast charge is allowed), so that the next data is referred to the command code of vbus _ OK, that is, whether the adapter output voltage is normal is detected, rather than 0XA8 code which may cause glitch. When operating in power bank mode, it must wait to a certain 0XA8,

because the last three bits of the 10 bits returned to the adapter are 101 in the power _ bank mode, and the effect of the glitch is now that the data to be returned moves to the right by one bit, which is equivalent to that the last bit is not returned to the adapter, and the last three bits received by the adapter cannot be 101, it is necessary to set bit4 to 0 to indicate that the fast charging is not allowed, and under the condition that the fast charging is not allowed, the adapter will always send 0XA8 to the protocol physical layer, and the protocol physical layer establishes a direct charging communication link after receiving a data code of 0XA8 without the glitch. In application, the actual test result is equal to 3 times at most, a direct charging communication link can be established, namely, no burr signal exists in the fourth reference data information center after the burr signal is received for three times, the entering of the scheme can be delayed by 200ms, but the problem that the fast charging cannot be entered due to misjudgment caused by burrs can be solved.

In an example embodiment of the present disclosure, after performing multiple verifications, step S418 may be further performed, it is determined that the adapter is VOOC2.0 and the code is VOOC2.0, then step S419 is performed, it is determined whether to allow fast charging, if so, step S420 is performed, fastchg-dummy is set to true and is notified to the core processor through the GLINK, and if not, step S421 is performed, and fastchg-dummy is set to false and is notified to the core processor through the GLINK.

When the mobile terminal operates in the non-fast charge mode, step S414 may be executed, Bit4 sets that fast charge is not allowed, step S415 determines that the adapter is VOOC2.0 and the code is VOOC2.0, and step S416 is executed to configure fastchg _ allow as false, that is, the configuration information is that fast charge is not allowed.

In summary, according to the technical solution of the present example, the error data information corresponding to the target data information is determined, the obtained reference data information is compared with the target data information and the error data information, and multiple times of verification are performed to obtain the target type of the adapter, so that misjudgment of the adapter type due to the glitch signal at the fixed position can be prevented.

In this exemplary embodiment, the duration of each clock signal may also be detected, and when the duration is greater than or equal to the preset time, the clock signal is determined to be normal data information, and if the duration is less than the preset time, the clock signal is determined to be a glitch signal, and the glitch signal is filtered, that is, the clock signal whose duration is less than or equal to the preset time is not responded.

Secondly, the present disclosure further provides a new interactive system of a power supply device and an adapter, where the power supply device includes a protocol physical layer, the protocol physical layer can execute the above interactive method of the power supply device and the adapter, and the specific steps of the interaction between the power supply device and the adapter have been described in detail above, and therefore, are not described herein again.

The core processor 200 may be connected to the dsp 140 via a GLINK bus.

In an example embodiment of the present disclosure, the power supply device may further include a data acquisition module 150, where the data acquisition module 150 is integrated with the device to be charged, and is configured to acquire the attribute information of the battery 160 and transmit the attribute information to the digital signal processor 140. The attribute information may include information such as voltage, current, and temperature of the battery 160, the data acquisition module 150 may include a fuel gauge, and may further include a detection device such as a temperature sensor, a voltage meter, and an ammeter, which are not specifically limited in this exemplary embodiment, along with a change in the amount of the attribute information that needs to be detected, a detection device corresponding to information in the attribute information may be set in the data acquisition module 150, for example, when the remaining power of the battery 160 needs to be detected, one coulometer may be added to detect the remaining power.

In the present exemplary embodiment, the data acquisition module 150 may be connected to the digital signal processor 140 through an I2C bus, so as to transmit the attribute information to the digital signal processor 140.

In the real-time manner of this example, the data acquisition module 150 may acquire the attribute information of the battery 160 once every other preset time, where the preset time may be 5 milliseconds, 10 milliseconds, and the like, and may also be customized according to a user requirement, and is not specifically limited in this example embodiment.

In this exemplary embodiment, after receiving the attribute information acquired by the data acquisition module 150, the digital signal processor 140 performs analog-to-digital conversion on the attribute information by using the analog-to-digital conversion module 142, and the digital signal processor 140 may store the attribute information for a preset number of times, where the preset number may be 5 times, that is, when the attribute information is acquired for the sixth time, the attribute information acquired for the first time is released, and the preset number may also be 10 times, 15 times, and the like, and may also be customized according to a user requirement, which is not specifically limited in this exemplary embodiment.

In an example embodiment of the present disclosure, the protocol physical layer 122 is connected to the digital signal processor 140 and the adapter 110, and configured to transmit an attribute signal to the adapter 110 according to a preset protocol, so that the adapter 110 can adjust an output signal according to the attribute information, and simultaneously feed back a transmission completion signal of the attribute information to the digital signal processor 140, so that the digital signal processor 140 controls the charge controller 120 to generate a close control signal according to the transmission completion signal, where the protocol physical layer 122 may be implemented by a digital circuit state machine.

In the present exemplary embodiment, the battery 160 is a secondary battery 160, which can be recharged using the charging voltage provided by the adapter 110, and the battery 160 can also be formed by at least one battery 160 cell having a specific electronic voltage and capable of outputting a voltage. The battery 160 supplies data information about the battery 160, which may be included in the above-described attribute information, and the data information may include a full charge bit of the battery 160, a full charge capacity of the battery 160, and the like.

In the present exemplary embodiment, as shown in fig. 6, the protocol phy 122 may be connected to the digital signal processor 140 through a data transmission line 420 and an interrupt line 410; the protocol physical layer 122 may be connected to the adapter 110 via a universal serial bus. The data transmission line 420 may be an I2C bus, an SPI (Serial Peripheral Interface) bus, or an SPMI bus, which is not limited in this exemplary embodiment.

Specifically, referring to fig. 8, step S810 may be executed first, the digital signal processor 140 sends a handshake signal, when the protocol physical layer 122 receives the handshake signal sent by the digital signal processor 140, that is, it indicates that the charging interface is connected to the device to be charged, at this time, step S820 may be executed, the protocol physical layer 122 may jump to an IDLE state (IDLE state) to prepare DATA transmission, and at the same time, the handshake signal is sent to the adapter 110, the adapter 110 receives the handshake signal and then issues a protocol sending instruction, after the protocol physical layer 122 receives the protocol sending instruction, step S830 may be executed, the protocol physical layer 122 jumps to a DATA receiving state (RECV _ DATA state), and then the adapter 110 sends protocol content, where the protocol content may be DATA that needs to be received, that is, the DATA that needs to be received includes one or more of the above attribute information, the protocol content may also include a bit number of data to be received, for example, 8-bit data, 9-bit data, etc., and the protocol phy 122 includes a received data counting function in the received attribute information.

After the protocol physical layer 122 receives the protocol content, step S850 may be executed, in which the protocol physical layer 122 jumps to a WAIT for DATA transmission state (WAIT _ TX _ DATA state) and transmits a DATA acquisition instruction to the digital signal processor 140; after receiving the data acquisition instruction, the dsp 140 sends the attribute information to the protocol phy 122 according to the data acquisition instruction, where the attribute information includes all attribute information required in the protocol content, such as the current of the battery 160, the temperature of the battery 160, and the like. After the protocol physical layer 122 receives the attribute information, step S860 may be performed, in which the protocol physical layer 122 jumps to a DATA transmission state (SEND _ DATA state), then transmits the attribute information to the adaptor 110, and then jumps to an IDLE state (IDLE state).

In the present exemplary embodiment, when the protocol phy 122 does not receive the attribute information sent by the dsp 140, or the received attribute information is incomplete, that is, the data reception is wrong, step S840 may be executed to jump the protocol phy 122 to the off state (DISABLE state), where when the received attribute information is incomplete, for example, the data required to be obtained in the protocol content may include the voltage, the current, and the temperature of the battery 160, but the received attribute information includes only the voltage and the current of the battery 160, and there is no temperature information, and it is determined that the received attribute information is incomplete. For another example, the data that needs to be received in the protocol content is 8-bit data, but the attribute information received by the protocol physical layer 122 is not enough for 8-bit data, such as 6-bit data, 7-bit data, etc., step S840 may be executed to jump the protocol physical layer 122 to the off state (DISABLE state).

In the present exemplary embodiment, when the protocol physical layer 122 transmits the attribute information to the adapter 110, it is detected whether a transmission completion signal, that is, an electrical signal is the same level signal for a certain time, for example, a low level signal for 50 milliseconds, a high level signal for 40 milliseconds, or the like, has occurred when the attribute information is transmitted. The certain time may be 50 milliseconds, 40 milliseconds, 60 milliseconds, or the like, or may be customized according to user requirements, and the same level signal may be a high level signal or a low level signal, which is not specifically limited in this exemplary embodiment.

When the occurrence of the transmission completion signal is detected, indicating that the data transmission is normal and the data transmission is completed, step S820 may be executed to jump the protocol phy 122 to an IDLE state (IDLE state) and wait for the next round of data reception. If the transmission completion signal is not received after the data transmission is completed, that is, the protocol physical layer 122 is still transmitting data after the data with the corresponding bit number is transmitted, and it is determined that the transmission attribute information is abnormal, step S840 may be executed to jump the protocol physical layer 122 to a shutdown state (DISABLE state).
