Detailed Description
The invention is described in further detail below with reference to the figures and specific examples.
The first embodiment,
An embodiment of the present invention provides an information processing method, applied to an electronic device, as shown in fig. 1, including:
step 101: detecting the residual electric quantity of the electronic equipment, and acquiring the working state of the electronic equipment, wherein the electronic equipment at least comprises a first working state for representing that the electronic equipment is in a state capable of receiving an operation instruction of at least one peripheral and a second working state for representing that the electronic equipment is in a state capable of receiving only a starting operation instruction;
step 102: acquiring a switching state of a control mode of a charger chip of the electronic equipment based on the residual capacity and the working state of the electronic equipment;
step 103: when the control mode of the charger chip needs to be switched between a standard downlink port control mode and a charging downlink port control mode, increasing a transition mode aiming at the charger chip; wherein the transition mode is a mode in which only a charging current is supplied.
The embodiment is mainly applied to a system of an electronic device with a charger chip, wherein the charger chip is used for managing a charging process. Specifically, the charging management of the USB interface is controlled by a charger chip.
In step 101, the remaining power of the electronic device is detected, which may be detecting the power of a battery, and a power supply unit in the electronic device may be a rechargeable battery or a voltage transformation unit connected to an ac power supply, so that the current power of the battery can be detected as long as power can be supplied.
The method comprises the steps of obtaining the working state of the electronic equipment, wherein the electronic equipment at least comprises a first working state for representing that the electronic equipment is in a state capable of receiving an operation instruction of at least one peripheral and a second working state for representing that the electronic equipment is only in a state capable of receiving a starting operation instruction. The following is in the form of Advanced Configuration and Power Interface (ACPI) specification. This energy management can be accomplished, for example, by software controlled "on-off" systems, or by using a Modem signal to wake up and shut down the system. ACPI operates in several modes:
s0: normal; s1: the CPU stops operating. Awakening time: 0 second; s2: CPU is turned off, and wake-up time: 0.1 second; s3: the components except the memory stop working, and the wake-up time is as follows: 0.5 second; s4: the memory information is written into the hard disk, all the components stop working, and the wake-up time is as follows: 30 seconds, (sleep state); s5: and closing.
S1 ═ Standby. That is, the system is in low power supply state, the window or BIOS can set the screen signal output to be off, the hard disk stops running to enter standby state, and the power lamp is in flashing state. At this time, any one of the mouse and keyboard can be activated to wake up the computer.
S2＝>Power Standby。
S3 ═ Suspend to RAM. That is, all the data of the windows currently stored in the memory is kept still, and then "" false shutdown "" is entered. At this time, except that the memory needs power to hold data, other devices and apparatuses are all powered off.
S4 ═ Suspend to Disk. The data in the windows memory is completely stored in the hard disk. When the computer is started, the data can be directly and completely read from the place where the data are stored to the memory without running the application program.
S5＝>Shutdown。
Further, a method of determining the operating state of the electronic device, or specifically whether the system is in the S1 mode or the S3 mode, may detect a condition of the system: for example, in the S1 sleep mode of ACPI, only the CPU stops operating and the other devices remain powered on. In S3 mode (BIOS- > power management- > Suspend to RAM is set to Enable, and devices except the memory are all in power-off state). Alternatively, in S3 mode, the system is completely quiet, all fans are off, the system cannot wake up from the keyboard, and manual wake up can only be done by pressing the power button on the front panel.
In step 102, the manner of obtaining the control mode of the charger chip of the electronic device based on the remaining power and the working state of the electronic device may be determined based on a preset rule, where the control mode of the charger chip corresponds to the remaining power and the working state of the electronic device.
Specifically, see fig. 2, items in the table represent power supply modes of different power supplies, remaining power of the power supplies, and operating states of the electronic device, and corresponding control modes of different charger chips; for example, AC-mode-S0 indicates that, when the electronic device is in an operating state (normal operating state) of S0 when the power supply is powered by AC power, the control mode of the charger chip is CDP mode, that is, the control mode of the charging downstream port; in addition, the DC-mode-S0IN battery is greater than 20%, that is, the power supply is powered by DC, when the battery is operated in the S0 operating state and the remaining power of the power supply is greater than 20%, the corresponding control mode of the charger chip is the CDP mode, and the like, and the descriptions and interpretation manners of other items are the same as those of the foregoing two, and are not exhaustive here.
Acquiring a switching state of a control mode of a charger chip of the electronic equipment, wherein the switching state can be sent when the residual electric quantity of a power supply changes and/or the working state of the electronic equipment changes, and the control mode of the corresponding charger chip also sends switching; referring also to fig. 2, it is assumed that the electronic device is also powered by DC and operates in the S3 mode (sleep state), and when the remaining power of the power supply is switched from > 20% to < 20%, that is, from the item DC-mode-S3in battery > 20%, the corresponding control mode CDP is switched to the item DC-mode-S3in battery < 20%, the corresponding control mode SDP is a switching state of the control mode of the charger chip. Of course, there may also be a switching state of the control mode for switching the SDP to the CDP, and the like, and specifically, a plurality of switching states may be obtained by comparing with different items shown in fig. 2, which is not exhaustive here.
In step 103, when the control mode of the charger chip needs to be switched between the standard downlink port control mode and the charging downlink port control mode, a transition mode for the charger chip is added, that is, when the control mode is switched between the standard downlink port control mode and the charging downlink port control mode, a mode that only provides a charging current is added, so as to avoid the problem of power failure of the charging port during switching of the control modes, that is, the problem of power failure of Vbus is avoided.
Specifically, the control modes of the charger chip may include CDP, SDP, DCP, and the like; the BC1.2 specification briefly specifies three different types of USB ports and two key objects. A "charge" port is a port that can provide a current of more than 500 mA; the "downstream" port transmits data according to the USB2.0 specification. The BC1.2 specification also determines how each port should be enumerated to the end device, as well as the protocol that identifies the application port type. The three USB BC1.2 port types are SDP, DCP, and CDP:
SDP, such a port has 15k Ω pull-down resistors on the D + and D-lines. The power consumption is 2.5mA when the power supply is hung, 100mA when the power supply is connected, and 500mA when the power supply is connected and configured to be higher;
a Dedicated Charging Port (DCP) which does not support any data transfer but is capable of supplying currents above 1.5A.
CDP, such port supports both high current charging and data transfer that is fully USB2.0 compatible. The port has the 15k omega pull-down resistors necessary for D + and D-communications, as well as internal circuitry for the charger detection phase switching.
By adopting the mode, the residual capacity and the working mode of the electronic equipment can be detected, and when the control mode of the charger chip is determined to be required to be switched between two target modes based on the residual capacity and the working mode, a transition mode which only provides charging current is added, so that the problem that power cannot be supplied through a USB port when the control mode of the charger chip is switched is avoided, and the working performance of the electronic equipment is ensured.
Example II,
An embodiment of the present invention provides an information processing method, applied to an electronic device, as shown in fig. 1, including:
step 101: detecting the residual electric quantity of the electronic equipment, and acquiring the working state of the electronic equipment, wherein the electronic equipment at least comprises a first working state for representing that the electronic equipment is in a state capable of receiving an operation instruction of at least one peripheral and a second working state for representing that the electronic equipment is in a state capable of receiving only a starting operation instruction;
step 102: acquiring a switching state of a control mode of a charger chip of the electronic equipment based on the residual capacity and the working state of the electronic equipment;
step 103: when the control mode of the charger chip needs to be switched between a standard downlink port control mode and a charging downlink port control mode, increasing a transition mode aiming at the charger chip; wherein the transition mode is a mode in which only a charging current is supplied.
The embodiment is mainly applied to a system of an electronic device with a charger chip, wherein the charger chip is used for managing a charging process. Specifically, the charging management of the USB interface is controlled by a charger chip.
In step 101, the remaining power of the electronic device is detected, which may be detecting the power of a battery, and a power supply unit in the electronic device may be a rechargeable battery or a voltage transformation unit connected to an ac power supply, so that the current power of the battery can be detected as long as power can be supplied.
The method comprises the steps of obtaining the working state of the electronic equipment, wherein the electronic equipment at least comprises a first working state for representing that the electronic equipment is in a state capable of receiving an operation instruction of at least one peripheral and a second working state for representing that the electronic equipment is only in a state capable of receiving a starting operation instruction. In the following, the specification of ACPI is given. This energy management can be accomplished, for example, by software controlled "on-off" systems, or by using a Modem signal to wake up and shut down the system. ACPI operates in several modes:
s0: normal; s1: the CPU stops operating. Awakening time: 0 second; s2: CPU is turned off, and wake-up time: 0.1 second; s3: the components except the memory stop working, and the wake-up time is as follows: 0.5 second; s4: the memory information is written into the hard disk, all the components stop working, and the wake-up time is as follows: 30 seconds, (sleep state); s5: and closing.
In step 102, the manner of obtaining the control mode of the charger chip of the electronic device based on the remaining power and the operating state of the electronic device may include:
when the working state of the electronic equipment is switched between a first working state and a second working state and the residual capacity of the electronic equipment in the second working state is a second residual capacity, determining that the electronic equipment needs to be switched between a standard downlink port mode and a charging downlink port mode;
when the electronic equipment is in a second working state and the residual capacity of the electronic equipment is switched between the first residual capacity and the second residual capacity, it is determined that the electronic equipment needs to be switched between a standard downlink port mode and a charging downlink port mode.
It should be noted that the second remaining power is a power smaller than a preset threshold; the first residual electric quantity is an electric quantity larger than a preset threshold value; the preset threshold may be a proportional value, and is set according to an actual situation, and is usually set to 20%.
Specifically, see fig. 2, items in the table represent power supply modes of different power supplies, remaining power of the power supplies, and operating states of the electronic device, and corresponding control modes of different charger chips; for example, AC-mode-S0 indicates that, when the electronic device is in an operating state (normal operating state) of S0 when the power supply is powered by AC power, the control mode of the charger chip is CDP mode, that is, the control mode of the charging downstream port; in addition, the DC-mode-S0IN battery is greater than 20%, that is, the power supply is powered by DC, when the battery is operated in the S0 operating state and the remaining power of the power supply is greater than 20%, the corresponding control mode of the charger chip is the CDP mode, and the like, and the descriptions and interpretation manners of other items are the same as those of the foregoing two, and are not exhaustive here.
Acquiring a switching state of a control mode of a charger chip of the electronic equipment, wherein the switching state can be sent when the residual electric quantity of a power supply changes and/or the working state of the electronic equipment changes, and the control mode of the corresponding charger chip also sends switching; referring also to fig. 2, it is assumed that the electronic device is also powered by DC and operates in the S3 mode (sleep state), and when the remaining power of the power supply is switched from > 20% to < 20%, that is, from the item DC-mode-S3in battery > 20%, the corresponding control mode CDP is switched to the item DC-mode-S3in battery < 20%, the corresponding control mode SDP is a switching state of the control mode of the charger chip. Of course, there may also be a switching state of the control mode for switching the SDP to the CDP, and the like, and specifically, a plurality of switching states may be obtained by comparing with different items shown in fig. 2, which is not exhaustive here.
In step 103, when the control mode of the charger chip needs to be switched between the standard downlink port control mode and the charging downlink port control mode, a transition mode for the charger chip is added, that is, when the control mode is switched between the standard downlink port control mode and the charging downlink port control mode, a mode that only provides a charging current is added, so as to avoid the problem of power failure of the charging port during switching of the control modes, that is, the problem of power failure of Vbus is avoided.
Specifically, the control modes of the charger chip may include CDP, SDP, DCP, and the like; the BC1.2 specification briefly specifies three different types of USB ports and two key objects. A "charge" port is a port that can provide a current of more than 500 mA; the "downstream" port transmits data according to the USB2.0 specification. The BC1.2 specification also determines how each port should be enumerated to the end device, as well as the protocol that identifies the application port type. The three USB BC1.2 port types are SDP, DCP, and CDP:
SDP, such a port has 15k Ω pull-down resistors on the D + and D-lines. The power consumption is 2.5mA when the power supply is hung, 100mA when the power supply is connected, and 500mA when the power supply is connected and configured to be higher;
DCP, a port that does not support any data transfer but is capable of supplying currents above 1.5A.
CDP, such port supports both high current charging and data transfer that is fully USB2.0 compatible. The port has the 15k omega pull-down resistors necessary for D + and D-communications, as well as internal circuitry for the charger detection phase switching.
Further, the method further comprises: and inputting a corresponding control mode to the charger chip through at least one target interface.
Specifically, the at least one target interface comprises: a first target interface, a second target interface, and a third target interface; each target interface acquires a control signal by receiving a high level or a low level;
accordingly, the method can be used for solving the problems that,
the receiving, through at least one target interface, a control pattern for the charger chip includes:
respectively receiving a high-level or low-level control signal based on the first target interface, the second target interface and the third target interface;
and taking the control signals received through the first target interface, the second target interface and the third target interface as control instructions, and adjusting the control mode aiming at the charger chip based on the control instructions.
For example, referring to fig. 3, the chip shown in the figure may be understood as a charger chip, and it can be seen that the chip shown in the figure has a plurality of pins, only three pins of 6, 7, and 8 are described in this embodiment, and the three target interfaces may be divided into three pins of 6, 7, and 8.
Control signals for the charger chip are received through three pins 6, 7, and 8 shown in fig. 3, and specifically, the three pins 6, 7, and 8 receive three signals CTL1, CTL2, and CTL3, respectively.
Still further, CTL1, 2, 3 may be understood as an information input interface, primarily for receiving switching instructions for control modes.

The control signals may be ordered, typically in the order of first target interface-second target interface-third target interface.
Still referring to fig. 3, the signals received by the CTL1, 2, and 3 are sorted according to the order corresponding to the CTL1, 2, and 3, and corresponding control instructions are obtained to switch the control mode of the charger chip.
Referring to fig. 4, CTL1, CTL2, and CTL3 use high level H or low level L as control signals, high level H as 1, and low level L as 0; for example, when entering the SDP from the CDP, or entering the CDP from the SDP, transition is performed using Dcp _ Auto;
specifically, the method comprises the following steps:
by adopting the mode, the residual capacity and the working mode of the electronic equipment can be detected, and when the control mode of the charger chip is determined to be required to be switched between two target modes based on the residual capacity and the working mode, a transition mode which only provides charging current is added, so that the problem that power cannot be supplied through a USB port when the control mode of the charger chip is switched is avoided, and the working performance of the electronic equipment is ensured.

Further, a method of determining the operating state of the electronic device, or specifically whether the system is in the S1 mode or the S3 mode, may detect a condition of the system: for example, in the S1 sleep mode of ACPI, only the CPU stops operating and the other devices remain powered on. In S3 mode (BIOS- > power management- > Suspend to RAM is set to Enable, and devices except the memory are all in power-off state). Alternatively, in S3 mode, the system is completely quiet, all fans are off, the system cannot wake up from the keyboard, and manual wake up can only be done by pressing the power button on the front panel.
The charger chip control unit 52 is configured to determine, based on a preset rule, a control mode of the charger chip corresponding to the remaining power and the operating state of the electronic device.
Specifically, see fig. 2, items in the table represent power supply modes of different power supplies, remaining power of the power supplies, and operating states of the electronic device, and corresponding control modes of different charger chips; for example, AC-mode-S0 indicates that, when the electronic device is in an operating state (normal operating state) of S0 when the power supply is powered by AC power, the control mode of the charger chip is CDP mode, that is, the control mode of the charging downstream port; in addition, the DC-mode-S0IN battery is greater than 20%, that is, the power supply is powered by DC, when the battery is operated in the S0 operating state and the remaining power of the power supply is greater than 20%, the corresponding control mode of the charger chip is the CDP mode, and the like, and the descriptions and interpretation manners of other items are the same as those of the foregoing two, and are not exhaustive here.
Acquiring a switching state of a control mode of a charger chip of the electronic equipment, wherein the switching state can be sent when the residual electric quantity of a power supply changes and/or the working state of the electronic equipment changes, and the control mode of the corresponding charger chip also sends switching; referring also to fig. 2, it is assumed that the electronic device is also powered by DC and operates in the S3 mode (sleep state), and when the remaining power of the power supply is switched from > 20% to < 20%, that is, from the item DC-mode-S3in battery > 20%, the corresponding control mode CDP is switched to the item DC-mode-S3in battery < 20%, the corresponding control mode SDP is a switching state of the control mode of the charger chip. Of course, there may also be a switching state of the control mode for switching the SDP to the CDP, and the like, and specifically, a plurality of switching states may be obtained by comparing with different items shown in fig. 2, which is not exhaustive here.
When the control mode of the charger chip needs to be switched between the standard downlink port control mode and the charging downlink port control mode, a transition mode aiming at the charger chip is added, namely, when the control mode of the charger chip is switched between the standard downlink port control mode and the charging downlink port control mode, a mode only providing charging current is added, so that the problem that the charging port is powered down when the control mode is switched is avoided, namely the problem that Vbus is powered down is avoided.
Specifically, the control modes of the charger chip may include CDP, SDP, DCP, and the like; the BC1.2 specification briefly specifies three different types of USB ports and two key objects. A "charge" port is a port that can provide a current of more than 500 mA; the "downstream" port transmits data according to the USB2.0 specification. The BC1.2 specification also determines how each port should be enumerated to the end device, as well as the protocol that identifies the application port type. The three USB BC1.2 port types are SDP, DCP, and CDP:
SDP, such a port has 15k Ω pull-down resistors on the D + and D-lines. The power consumption is 2.5mA when the power supply is hung, 100mA when the power supply is connected, and 500mA when the power supply is connected and configured to be higher;
DCP, a port that does not support any data transfer but is capable of supplying currents above 1.5A.
CDP, such port supports both high current charging and data transfer that is fully USB2.0 compatible. The port has the 15k omega pull-down resistors necessary for D + and D-communications, as well as internal circuitry for the charger detection phase switching.
By adopting the mode, the residual capacity and the working mode of the electronic equipment can be detected, and when the control mode of the charger chip is determined to be required to be switched between two target modes based on the residual capacity and the working mode, a transition mode which only provides charging current is added, so that the problem that power cannot be supplied through a USB port when the control mode of the charger chip is switched is avoided, and the working performance of the electronic equipment is ensured.
Example four,

Still further, CTL1, 2, 3 may be understood as an information input interface, primarily for receiving switching instructions for control modes.
The control signals received through the first target interface, the second target interface and the third target interface are used for adjusting the control mode for the charger chip, in the process, the control signals of the three target interfaces can be respectively sequenced, and all the sequenced control signals are used as control instructions for adjusting the control mode for the charger chip. The control signals may be ordered, typically in the order of first target interface-second target interface-third target interface.
Still referring to fig. 3, the signals received by the CTL1, 2, and 3 are sorted according to the order corresponding to the CTL1, 2, and 3, and corresponding control instructions are obtained to switch the control mode of the charger chip.
Referring to fig. 4, CTL1, CTL2, and CTL3 use high level H or low level L as control signals, high level H as 1, and low level L as 0; for example, when entering SDP1 from CDP, or CDP from SDP1, transition is made using Dcp _ Auto;
specifically, the method comprises the following steps:
by adopting the mode, the residual capacity and the working mode of the electronic equipment can be detected, and when the control mode of the charger chip is determined to be required to be switched between two target modes based on the residual capacity and the working mode, a transition mode which only provides charging current is added, so that the problem that power cannot be supplied through a USB port when the control mode of the charger chip is switched is avoided, and the working performance of the electronic equipment is ensured.
