All other embodiments that can be derived from the embodiments given herein by a person of ordinary skill in the art are intended to be within the scope of the present disclosure.
The embodiment of the application provides a charge and discharge control method, a charge and discharge control device, charge and discharge control equipment and a charge and discharge control medium. In the embodiment of the application, for the USB device with the Source mode, when the remaining power is less than the preset power threshold, the USB device is controlled to enter the stop mode, wherein the USB device is not charged or discharged in the stop mode, so that the USB device with the Source mode does not discharge all the time, which causes power exhaustion, and other USB devices are not required to supply power to the USB device, thereby avoiding the power exhaustion of the two USB devices.
Fig. 1 is a schematic view of a charge and discharge control process provided in an embodiment of the present application, where the process specifically includes the following steps:
s101: and when the current power mode of the USB equipment is recognized to be the Source mode, acquiring the information of the residual electric quantity.
The embodiment of the application is applied to any USB device based on the USB Type-C interface connection, and the USB device can be a mobile terminal, a tablet computer and the like.
Two USB equipment through USB Type-C interface connection can charge and discharge based on the USB PD agreement, in order to can distinguish the power mode that the both ends USB equipment is located, can discern based on the power mode of USB Type-C interface of USB equipment. If the current power mode of the USB device is identified as the Source mode, that is, the power supply mode, in order to avoid the problem that the power supply of the USB device is always supplied to the outside, which causes the power amount of the USB device to be too low, in the embodiment of the present application, the information of the remaining power amount of the USB device may be obtained when the power mode of the USB device is identified as the Source mode.
In the embodiment of the application, in order to control the USB device in time, the power mode of the USB device may be obtained according to a set time interval, and when it is recognized that the current power mode of the USB device is a Source mode, information of the remaining power of the USB device is obtained.
S102: and judging whether the residual electric quantity of the USB equipment is smaller than a preset electric quantity threshold, if so, executing S103, otherwise, executing S104.
In order to prevent the USB device from consuming power, the USB device that originally absorbs power supplies power to the USB device that is not powered, in turn, until the power consumption of the two USB devices is completed, in this embodiment of the present application, a power threshold is preset, where the power threshold may be a specific power value or a specific value. If the power mode is the Source mode, the USB equipment has more residual capacity when exiting the Source mode, the capacity threshold value can be set to be larger, if the USB equipment wants to supply power to other USB equipment as far as possible, the capacity threshold value can be set to be smaller, and the capacity threshold value can be flexibly set according to the requirement.
S103: and if the residual electric quantity is smaller than a preset electric quantity threshold value, controlling the USB equipment to enter a stop state mode, wherein the USB equipment is not charged or discharged after entering the stop state mode.
When the USB device continuously supplies power to other USB devices connected to the USB device, the remaining power of the USB device itself is inevitably reduced. In the embodiment of the application, in order to control the USB device in time, the power mode of the USB device may be obtained according to a set time interval, and when it is recognized that the current power mode of the USB device is a Source mode, information of the remaining power of the USB device is obtained.
After the residual electric quantity of the USB equipment is obtained, comparing the residual electric quantity with a preset electric quantity threshold value, judging whether the residual electric quantity of the USB equipment is smaller than the preset electric quantity threshold value, if the residual electric quantity is smaller than the preset electric quantity threshold value, indicating that the USB equipment can not continuously supply power to other USB equipment connected with the USB equipment at the moment, controlling the USB equipment to close a power supply and stop supplying power to other USB equipment connected with the USB equipment, simultaneously controlling the USB equipment to exit a Source mode, setting a stop sign, and entering a stop state mode. The stop state mode is an intermediate state, which is different from the Source mode and the Sink mode, and the USB device does not discharge nor recharge after entering the stop state mode.
S104: and if the residual electric quantity is not less than a preset electric quantity threshold value, controlling the USB equipment to be kept in the Source mode.
If the residual electric quantity is not less than the preset electric quantity threshold value, which indicates that the USB equipment still has enough electric quantity to supply power outwards, the USB equipment is controlled to be kept in the Source mode, and power is continuously supplied to other USB equipment connected with the USB equipment.
In the embodiment of the application, for the USB device with the Source mode, when the remaining power is less than the preset power threshold, the USB device is controlled to enter the stop mode, wherein the USB device is not charged or discharged when in the stop mode, so that the USB device with the Source mode does not discharge all the time, which causes power exhaustion, and other USB devices are not required to supply power to the USB device, thereby avoiding the power exhaustion of the two USB devices.
On the basis of the above embodiment, in the embodiment of the present application, if it is recognized that the current power mode of the USB device is the Sink mode, the USB device is controlled to absorb the power of other devices connected to the USB device.
For two USB devices connected via a USB Type-C interface, the power modes of the USB Type-C interface occur in pairs, i.e., one USB device is supplying power and the other is necessarily drawing power, and vice versa. Therefore, when two USB devices are connected based on the USB Type-C interface, the power mode of one of the two USB devices is the Source mode, and the power mode of the other USB device is the Sink mode. When the current power mode of the USB device is identified to be the Sink mode, the USB device in the Sink mode is powered up, that is, charged, and as long as the USB device in the Source mode supplies power to the outside, the USB device in the Sink mode can continue to be kept in the Sink mode and continue to absorb the electric quantity of other USB devices connected with the USB device.
On the basis of the foregoing embodiments, in the embodiment of the present application, the entering of the USB device into the Source mode specifically includes:
the USB equipment and other equipment connected with the USB equipment determine to enter a Source mode through USB PD interactive negotiation; or receiving an instruction of switching from a Sink mode to a Source mode, and enabling the USB equipment to enter the Source mode.
Based on the USB PD protocol, the power modes of the USB devices may be switched, as shown in fig. 2, which is a schematic diagram illustrating power mode switching based on the USB PD protocol in the related art, as shown in fig. 2, after the two USB devices successfully establish a connection and the power mode of the USB Type-C interface is established, one of the USB devices is in a Source mode, i.e., a discharge state, and the other USB device is in a Sink mode, i.e., a power-up state, and the two USB devices may switch the power modes based on the USB PD protocol.
In addition, when two USB devices are connected for the first time, the power mode of the USB Type-C interface is determined based on the negotiation of the USB PD protocol, the USB devices are randomly in a Source mode or a Sink mode, and the mode switching can be performed through manual control of a switch of the USB devices. Specifically, in the later stage, when the power mode of the USB device is switched, a mode switching instruction may be sent to the USB device, and the USB device enters the corresponding mode after receiving the instruction. If the USB equipment is controlled to be switched from the Sink mode to the Source mode, an instruction for switching from the Sink mode to the Source mode can be sent to the USB equipment, and after the USB equipment receives the instruction for switching from the Sink mode to the Source mode, the USB equipment enters the Source mode.
In order to implement the relevant switching between the modes, on the basis of the foregoing embodiments, in an embodiment of the present application, the method further includes:
receiving an instruction for switching from a stop state mode to a Sink mode;
and controlling the USB equipment to enter a Sink mode according to the instruction.
When the USB equipment is in the stop state mode, the USB equipment can be controlled to be switched to the Sink mode from the current state through the control menu. Specifically, when mode switching is implemented, an instruction for switching to a Sink mode may be sent to the USB device, where the instruction may specifically be an instruction for switching to the Sink mode input through a control menu, and when the USB device receives the instruction for switching to the Sink mode, the USB device is controlled to enter the Sink mode and start to absorb electric quantities of other USB devices connected to the USB device.
Fig. 3 is a schematic diagram illustrating power mode switching of a USB device according to an embodiment of the present application, where after two USB devices are successfully connected based on a USB Type-C interface, a power mode of the USB device may be in a Source mode or a Sink mode, and when a remaining power of the USB device in the Source mode is smaller than a preset power threshold, the USB device is in a stop state mode.
As shown in fig. 3, after the two USB devices successfully establish a connection and the power mode of the USB Type-C interface is established, one of the USB devices is in a Source mode, i.e., a discharge state, and the other USB device is in a Sink mode, i.e., a power-up state, the two USB devices may switch the power modes based on the USB PD protocol.
The USB device can be switched from the Source mode in the discharge state to the Sink mode in the power absorption state through manual control or control of a control menu, and can also be switched from the Sink mode in the power absorption state to the Source mode in the discharge state.
When the current power mode of the USB equipment is recognized to be the Source mode, the USB equipment acquires the information of the self residual electric quantity, if the residual electric quantity is smaller than a preset electric quantity threshold value, the USB equipment exits the Source mode and enters a stop state mode, and the USB equipment is not charged or discharged after entering the stop state mode.
When the USB device is in the stop state mode, the USB device may be controlled to switch from the current state to the Sink mode through the control menu, and specifically, when the USB device receives an instruction to switch to the Sink mode, the USB device is controlled to enter the Sink mode to start absorbing the electric quantity of other USB devices connected to the USB device.
According to the charge and discharge control method provided by the embodiment of the application, after the two USB devices are successfully connected based on the USB Type-C interface, the USB devices may be in a Source mode, namely a power supply mode, or may be in a Sink mode, namely a power absorption mode, based on the randomness of the negotiation of the USB PD protocol. Due to the randomness of the negotiation of the USB PD protocol, if a USB device with high electric quantity is to supply power to a device with low electric quantity, the USB device with low electric quantity may be in a Source mode to supply power to the device with high electric quantity, and at the moment, the power state of the USB device can be flexibly switched through the control menu, so that the USB device with high electric quantity is switched to the Source mode to supply power to the USB device with low electric quantity. Unnecessary troubles caused by wrong charging and discharging due to the fact that the current power mode of the USB device is not matched with the real life requirements are effectively avoided.
In addition, when the USB equipment with high power supply supplies power for the USB equipment with low power supply, and when the residual power of the USB equipment as the power supply equipment is smaller than a preset power threshold value, the USB equipment automatically exits from the Source mode, sets a stop sign, enters into a stop state mode, and is neither charged nor discharged. The embodiment of the application determines whether the current USB equipment enters the stop state mode or not based on the preset electric quantity threshold value, and avoids the phenomenon that the USB equipment exits the Source mode due to the exhaustion of electric quantity, can be switched to the Sink mode to absorb the electric quantity of other USB equipment connected with the Sink mode, and then absorbs the electric quantity provided for the USB equipment at the opposite end. The embodiment of the application provides a charge and discharge control method, which does not cause charge and discharge reciprocation, and certainly does not bring about electric quantity loss caused by heat generated by reciprocating charge and discharge.
The following describes in detail the charge and discharge control according to an embodiment of the present application with reference to a specific embodiment, and fig. 4 is a control flow chart of a charge and discharge control method according to the present application, where the specific control flow is as follows:
