Description
Technical Field
The present invention relates to the field of charging, and in particular, to a charging method, a charging device, and a terminal.
Background
As the terminal functions become more powerful and the power consumption becomes more severe, the standby time is gradually shortened, and the fast charging mode becomes the best means for solving the power consumption problem when the terminal user increasingly emphasizes the standby time. Various charging protocols are currently available, such as a PD (Power Delivery) charging Protocol, a PE (Pump Express) charging Protocol, a QC (Quick Charge) charging Protocol, an FCP (Fast Charge Protocol) charging Protocol, an SCP (Super Charge Protocol) charging Protocol, a VOOC (flash Protocol) charging Protocol, and the like. Some protocols are quick charging protocols which are designed by some organizations and have universality, for example, a PD charging protocol is a charging protocol published by a USB-IF organization, and a plurality of mobile phone manufacturers can set a private charging protocol based on the performance of the mobile phones of the manufacturers, so that the quick charging function is more adaptive to the mobile phones of the manufacturers.
At present, products such as an adapter, a vehicle charger, a mobile power supply, a mobile terminal and the like supporting a quick charging mode are widely used by users. In order to be suitable for various charging protocols, products such as an adapter and a mobile power supply support various charging protocols, for example, one adapter simultaneously supports a QC charging protocol and a PD charging protocol, so that a mobile terminal supporting the QC charging protocol and the adapter can perform quick charging communication of the QC charging protocol, and a mobile terminal supporting the PD charging protocol and the adapter can perform quick charging communication of the PD charging protocol, thereby increasing the applicability of the adapter; for another example, another mobile terminal supports both the quick charging mode of the QC charging protocol and the quick charging mode of the PD charging protocol, so that the mobile terminal performs quick charging according to the quick charging mode of the PD charging protocol when accessing the adapter supporting the PD charging protocol, and performs quick charging according to the mode of the QC charging protocol when accessing the adapter supporting the QC charging protocol, thereby increasing the charging experience of the mobile terminal.
However, in the above process, the inventor finds that, considering that each manufacturer of the mobile terminal has its own private charging protocol, and the private charging protocol has a protection measure for the mobile terminal of its manufacturer, the security is higher, but since the handshake speed of the specified charging protocol (such as the PD charging protocol, the QC charging protocol, and the PE charging protocol) is faster, the mobile terminal is usually charged quickly according to the specified charging protocol, so that the usage rate of the private charging protocol is reduced, and the security of the quick charging is reduced.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a flowchart of a charging method provided in the embodiment of the present invention is shown, and is applied to a mobile terminal, where the method specifically includes the following steps:
In the embodiment of the present invention, the mobile terminal includes, but is not limited to, a terminal such as a mobile phone, a tablet computer, a notebook computer, a palm top computer, a navigation device, a wearable device, a smart band, a pedometer, and the like, and the mobile terminal supports multiple protocols, where the multiple protocols include a first charging protocol and a second charging protocol, the first charging protocol may be a specific charging protocol (such as a PD charging protocol, a PE charging protocol, or a QC charging protocol, and the like), the second charging protocol may be a private charging protocol (such as a dual engine fast charging protocol, an SCP charging protocol, an FCP charging protocol, or a VOOC charging protocol, and the like), and similarly, a device connected to the mobile terminal in the present invention may also support multiple protocols, which is not particularly limited in the embodiment of the present invention.
Wherein the mobile terminal access device is determined upon detecting the presence of a voltage on the Vbus line. At this time, under the condition that the interfaces of the mobile terminal and the device are Tpye-C interfaces, the device may be a charging terminal or a power receiving terminal, at this time, whether the device is the charging terminal or not can be distinguished according to a Toggle mode specified by a Tpye-C interface protocol, that is, the mobile terminal can send a high-level signal to the device and detect whether the level of the high-level signal is pulled down after reaching the device, if the level of the high-level signal is pulled down, the device is determined to be the power receiving terminal, and if the level of the high-level signal is not pulled down, the device is determined to be the charging terminal. In the case that the interface of the mobile terminal is a Tpye-C interface and the interface of the device is a Tpye-a interface, since Tpye-a is usually connected as a charging terminal, the device connected to the mobile terminal is determined as the charging terminal according to the interface type of the device.
And 102, shielding communication information sent by the charging terminal according to a first charging protocol under the condition that the equipment is identified as the charging terminal, and communicating with the charging terminal according to a second charging protocol.
When the first charging protocol is a PD charging protocol, the device needs to detect whether the mobile terminal is connected with an RP resistor, and may send a handshake request of the PD charging protocol when the mobile terminal is connected with the RP resistor.
For the second charging protocol, the charging terminal generally needs to determine whether the second charging protocol satisfies a handshake condition, and send out a handshake request of the second charging protocol if the second charging protocol satisfies the handshake condition.
In addition, because the first charging protocol and the second charging protocol are set to have different handshaking communication speeds, the first charging protocol has a higher handshaking communication speed than the second charging protocol, and then in the prior art, the mobile terminal may receive a handshaking request of the first charging protocol first and complete the handshaking operation of the first charging protocol to realize rapid charging according to the first charging protocol.
By adopting the method, the equipment connected with the mobile terminal is firstly identified, then the communication information sent by the charging terminal in a first charging protocol is shielded and the communication is carried out with the charging terminal according to a second charging protocol under the condition that the equipment is identified as the charging terminal, wherein the handshaking communication speed of the first charging protocol is faster than that of the second charging protocol. Therefore, the safety of the second charging protocol is higher, so that the second charging protocol is preferentially used for communicating with the charging terminal in the quick charging process of the mobile terminal, the utilization rate of the second charging protocol is improved, and the safety of quick charging is improved.
Referring to fig. 2, a flowchart of a charging method provided in the embodiment of the present invention is shown, and is applied to a mobile terminal, where the method specifically includes the following steps:
In the embodiment of the present invention, the mobile terminal includes, but is not limited to, a terminal such as a mobile phone, a tablet computer, a notebook computer, a palm-top computer, a navigation device, a wearable device, a smart band, a pedometer, and the like, and the mobile terminal supports multiple protocols, where the multiple protocols include a first charging protocol and a second charging protocol, the first charging protocol may be a specific charging protocol (such as a PD charging protocol, a PE charging protocol, or a QC charging protocol, and the like), the second charging protocol may be a private charging protocol (such as a dual engine fast charging protocol, an SCP charging protocol, an FCP charging protocol, or a VOOC charging protocol, and the like), and similarly, a device connected to the mobile terminal in the present invention may also support multiple protocols, which is not particularly limited in the embodiment of the present invention.
Wherein the mobile terminal access device is determined upon detecting the presence of a voltage on the Vbus line. At this time, under the condition that the interfaces of the mobile terminal and the device are Tpye-C interfaces, the device may be a charging terminal or a power receiving terminal, at this time, whether the device is the charging terminal or not can be distinguished according to a Toggle mode specified by a Tpye-C interface protocol, that is, the mobile terminal can send a high-level signal to the device and detect whether the level of the high-level signal is pulled down after reaching the device, if the level of the high-level signal is pulled down, the device is determined to be the power receiving terminal, and if the level of the high-level signal is not pulled down, the device is determined to be the charging terminal. In the case that the interface of the mobile terminal is a Tpye-C interface and the interface of the device is a Tpye-a interface, since Tpye-a is usually connected as a charging terminal, the device connected to the mobile terminal is determined as the charging terminal according to the interface type of the device.
Step 202, receiving a handshake request sent by the device when the device is identified as a charging end.
In a case that the first charging protocol is a PD charging protocol, the device needs to detect whether the mobile terminal is connected with an RP resistor, and in a case that the mobile terminal is connected with the RP resistor, a first request of the PD charging protocol may be sent, and the first request of the PD charging protocol may include different charging gears, so that after the mobile terminal determines that the handshake with the device is successful according to the first request of the PD charging protocol, the mobile terminal selects a target charging gear from a plurality of charging gears to perform charging, where the plurality of charging gears include: 5v, 9v, 12v, 20v, etc.
For the second charging protocol, the charging terminal generally needs to determine whether the second charging protocol satisfies a handshake condition, and send out a handshake request of the second charging protocol if the second charging protocol satisfies the handshake condition. For example, the handshake condition may be that a voltage value between D +/D-is greater than or equal to a preset voltage threshold, and in addition, in order to more accurately determine whether the second charging protocol satisfies the handshake condition, it is necessary to perform multiple detections on the voltage value between D +/D-, for example, the voltage value between D +/D-may be acquired according to a preset cycle within a preset time period, and the second charging protocol is determined to satisfy the handshake condition when the voltage values between D +/D-acquired within the preset time period are both greater than or equal to the preset voltage threshold; and determining that the second charging protocol does not satisfy the handshake condition under the condition that any voltage value between D +/D-acquired within the preset time period is smaller than the preset voltage threshold, and by the above manner, preventing the device connected with the mobile terminal from performing a misoperation.
Step 203, shielding the first request and informing the device to continue sending the handshake request when the handshake request is the first request of the first charging protocol and the handshake between the mobile terminal and the device is not successful.
In the embodiment of the present invention, because the handshake communication speeds set by the first charging protocol and the second charging protocol are different, the handshake communication speed of the first charging protocol is faster than that of the second charging protocol, and further, in the prior art, the mobile terminal may receive the first request of the first charging protocol first and complete the handshake operation of the first charging protocol, so as to implement the fast charging according to the first charging protocol. In addition, considering that the mobile terminal may have a handshake failure with the second charging protocol, and therefore still needs to be charged through the first charging protocol at this time, the present invention may notify the device to continue to send the first request, so as to shield the second request of the second charging protocol after the mobile terminal determines that the handshake failure of the second charging protocol occurs, and perform a handshake operation according to the first request of the first charging protocol that the device continues to send, and perform a fast charging according to the first charging protocol after the handshake with the first charging protocol succeeds.
Wherein notifying the device to continue sending handshake requests comprises: based on the first charging protocol, a reset command is sent to the device, so that the device is in a waiting state, and thus, the mobile terminal can still perform handshaking operation with the first charging protocol under the condition that the mobile terminal does not successfully handshake with the second charging protocol within a preset time period, and the problem that the mobile terminal cannot perform handshaking operation with the first charging protocol any more due to the fact that the charging terminal stops sending the first request after sending the first request for the preset times in the prior art is solved.
It should be noted that, after the handshake between the mobile terminal and the second charging protocol is successful, the mobile terminal will be charged according to the second charging protocol, and at this time, the device may be notified to stop sending the handshake request.
In addition, if the handshake request of the second charging protocol is waited for a long time, the charging efficiency is low, and the use experience of the user is reduced, therefore, the method and the mobile terminal can determine whether the second request of the second charging protocol is received in the specified time period, and if the second request of the second charging protocol is not received in the specified time period, the mobile terminal carries out handshake operation according to the first request continuously sent by the equipment, so that the charging is carried out through the first charging protocol after the handshake is successful, and the problem of low charging efficiency caused by waiting for the second request of the second charging protocol for a long time is solved.
And 204, in the case that the handshake request is a second request of the second charging protocol, in response to the second request, communicating with the charging terminal through the second charging protocol.
In the embodiment of the present invention, in a case that a handshake request is a second request of a second charging protocol, it is first determined whether the second charging protocol is a preset private charging protocol of a mobile terminal, and in a case that the second charging protocol is the preset private charging protocol of the mobile terminal, the mobile terminal needs to send a message verification request to a device, so that the device sends, in response to the message verification request, verification data to the mobile terminal, so that the mobile terminal determines whether the verification data is the preset data, and in a case that the verification data is the preset data, it is determined that the handshake of the second charging protocol is successful, and thus charging is performed through the second charging protocol; and under the condition that the second charging protocol is not a preset private charging protocol of the mobile terminal or the check data is not preset data, determining that the second charging protocol fails to handshake, wherein at the moment, the charging still needs to be carried out through the first charging protocol.
By adopting the method, the equipment connected with the mobile terminal is firstly identified, and then the handshake request sent by the equipment is received under the condition that the equipment is identified as a charging end; then shielding the first request and informing the equipment to continuously send a handshake request under the condition that the handshake request is a first request of a first charging protocol and the handshake between the mobile terminal and the equipment is not successful; and under the condition that the handshake request is a second request of a second charging protocol, the second request is responded, and communication is carried out with a charging terminal through the second charging protocol, wherein the handshake communication speed of the first charging protocol is faster than that of the second charging protocol. Therefore, the safety of the second charging protocol is higher, so that the second charging protocol is preferentially used for communicating with the charging terminal in the quick charging process of the mobile terminal, the utilization rate of the second charging protocol is improved, and the safety of quick charging is improved.
Referring to fig. 3, a flowchart of a charging method provided in the embodiment of the present invention is shown, and is applied to a mobile terminal, where the method specifically includes the following steps:
In the embodiment of the present invention, the mobile terminal includes, but is not limited to, a terminal such as a mobile phone, a tablet computer, a notebook computer, a palm top computer, a navigation device, a wearable device, a smart band, a pedometer, and the like, and the mobile terminal supports multiple protocols, where the multiple protocols include a first charging protocol and a second charging protocol, the first charging protocol may be a specific charging protocol (such as a PD charging protocol, a PE charging protocol, or a QC charging protocol, and the like), the second charging protocol may be a private charging protocol (such as a dual engine fast charging protocol, an SCP charging protocol, an FCP charging protocol, or a VOOC charging protocol, and the like), and similarly, a device connected to the mobile terminal in the present invention may also support multiple protocols, which is not particularly limited in the embodiment of the present invention.
Wherein the mobile terminal access device is determined upon detecting the presence of a voltage on the Vbus line. At this time, under the condition that the interfaces of the mobile terminal and the device are Tpye-C interfaces, the device may be a charging terminal or a power receiving terminal, at this time, whether the device is the charging terminal or not may be distinguished according to a Toggle mode specified by a Tpye-C interface protocol, that is, the mobile terminal may send a high level signal to the device, detect whether the level of the high level signal is pulled down after reaching the device, determine that the device is the power receiving terminal if the level of the high level signal is pulled down, and determine that the device is the charging terminal if the level of the high level signal is not pulled down. In the case that the interface of the mobile terminal is a Tpye-C interface and the interface of the device is a Tpye-a interface, since Tpye-a is usually connected as a charging terminal, the device connected to the mobile terminal is determined as the charging terminal according to the interface type of the device.
In a case that the first charging protocol is a PD charging protocol, the device needs to detect whether the mobile terminal is connected with an RP resistor, and in a case that the mobile terminal is connected with the RP resistor, a first request of the PD charging protocol may be sent, and the first request of the PD charging protocol may include different charging gears, so that after the mobile terminal determines that the handshake with the device is successful according to the first request of the PD charging protocol, the mobile terminal selects a target charging gear from a plurality of charging gears to perform charging, where the plurality of charging gears include: 5v, 9v, 12v, 20v, etc.
For the second charging protocol, the charging terminal generally needs to determine whether the second charging protocol satisfies a handshake condition, and send out a handshake request of the second charging protocol if the second charging protocol satisfies the handshake condition. For example, the handshake condition may be that a voltage value between D +/D-is greater than or equal to a preset voltage threshold, and in addition, in order to more accurately determine whether the second charging protocol satisfies the handshake condition, it is necessary to perform multiple detections on the voltage value between D +/D-, for example, the voltage value between D +/D-may be acquired according to a preset cycle within a preset time period, and the second charging protocol is determined to satisfy the handshake condition when the voltage values between D +/D-acquired within the preset time period are both greater than or equal to the preset voltage threshold; and determining that the second charging protocol does not satisfy the handshake condition under the condition that any voltage value between D +/D-acquired within the preset time period is smaller than the preset voltage threshold, and by the above manner, preventing the device connected with the mobile terminal from performing a misoperation.
In the embodiment of the present invention, because the handshake communication speeds set by the first charging protocol and the second charging protocol are different, the handshake communication speed of the first charging protocol is faster than that of the second charging protocol, and further in the prior art, the mobile terminal may receive the first request of the first charging protocol first and complete the handshake operation of the first charging protocol to realize fast charging according to the first charging protocol, however, the present invention considers that the security of the second charging protocol is higher, so that the mobile terminal may perform the handshake operation through the second charging protocol, and in addition, considers that before the second charging protocol succeeds in handshake, the mobile terminal is not charged, which results in a problem of low charging efficiency, thereby affecting the user experience, in summary, the present invention may perform handshake operation with the first charging protocol first after receiving the first request, and after the handshake is successful, the charging is carried out through the first charging protocol, so that the charging time can be effectively utilized. Wherein, in view of the safety of the charging process and the charging efficiency, the device may be informed to discharge at the lowest voltage, such as 5V, based on the first charging protocol.
In addition, considering that the mobile terminal may have a handshake failure with the second charging protocol, and thus if the charging terminal discharges at the lowest voltage all the time, the charging efficiency may be low, in the present invention, if a handshake failure of the second charging protocol is detected, the second charging protocol may be shielded, and the charging gear may be adjusted higher according to the first charging protocol, so as to improve the charging efficiency. Similarly, if the handshake request of the second charging protocol is waited for a long time, the charging efficiency is also low, therefore, the present invention can determine whether the second request of the second charging protocol is received within the specified time period, and if the second request of the second charging protocol is not received within the specified time period, the mobile terminal increases the charging gear according to the first charging protocol.
In addition, the mobile terminal of the present application may continue to receive the handshake request sent by the device during the charging process through the first charging protocol, and execute step 304 when the handshake request is the second request of the second charging protocol.
In the embodiment of the present invention, under the condition that the handshake request is a second request of a second charging protocol, it is first determined whether the second charging protocol is a preset private charging protocol of the mobile terminal, and under the condition that the second charging protocol is the preset private charging protocol of the mobile terminal, the mobile terminal needs to send a message verification request to the device, so that the device responds to the message verification request and sends verification data to the mobile terminal, so that the mobile terminal determines whether the verification data is preset data, and under the condition that the verification data is preset data, it is determined that the handshake of the second charging protocol is successful, so that charging is performed through the second charging protocol, and the first charging protocol is shielded; when the second charging protocol is not the preset private charging protocol of the mobile terminal, or when the verification data is not the preset data, the second charging protocol fails to handshake, and at this time, the charging is still performed through the first charging protocol.
By adopting the method, the equipment connected with the mobile terminal is firstly identified, and then the handshake request sent by the equipment is received under the condition that the equipment is identified as a charging end; then, under the condition that the handshake request is a first request of a first charging protocol and the mobile terminal does not successfully handshake with the equipment, responding to the first request, communicating with a charging terminal through the first charging protocol, and continuously receiving the handshake request sent by the equipment; and under the condition that the handshake request is a second request of a second charging protocol, responding to the second request, shielding communication information sent by the charging terminal in the first charging protocol, and communicating with the charging terminal through the second charging protocol, wherein the handshake communication speed of the first charging protocol is faster than that of the second charging protocol. Therefore, in the quick charging process of the mobile terminal, the mobile terminal can communicate with the charging terminal through the first charging protocol to perform quick charging under the condition that the mobile terminal does not successfully handshake with the equipment, and the second charging protocol has higher safety, so that the mobile terminal can still perform handshaking with the second charging protocol in the charging process, and the second charging protocol can communicate with the charging terminal through the second charging protocol after the second charging protocol succeeds in handshaking, so that the utilization rate of the second charging protocol is improved, the charging time is saved, and the safety of quick charging is improved.
