[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] It should be noted that the terms "first", "second", "third" and "fourth" in the specification and claims of the present application are used to distinguish different objects rather than to describe a specific order. The terms "including" and "having" in the embodiments of the present application and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device including a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0030] The embodiments of the present application disclose a power supply method and device, an electronic device, and a computer-readable storage medium, which can prevent overcurrent from being generated in a communication module in an electronic device.

[0031] The technical solution of the present application will be described in detail below in conjunction with specific embodiments.

[0032] In order to more clearly introduce the power supply method and device, electronic device, and computer-readable storage medium disclosed in the embodiments of the present application, firstly, an application scenario applicable to the method is introduced.

[0033] See also Figure 1 , Figure 1 Optionally, the method can be applied to a target processor 110 included in the electronic device, and the electronic device can also include a communication module 120, and the target processor 110 can be electrically connected to the communication module 120 for performing logic control on the communication module 120.

[0034] Optionally, the target processor 110 may include various devices with logic control capabilities and / or logic operation capabilities, including but not limited to a central processing unit (CPU), a single-chip microcomputer, etc., which are not limited here.

[0035] Optionally, the communication module 120 may include: a power supply unit 1201 , a target switch 1202 , and a signal transmission unit 1203 , which is not limited here.

[0036] The power supply unit 1201 may include a power supply and a modulation circuit. Optionally, the modulation circuit may include a direct current-to-direct current (DC_DC) modulation circuit, a direct current-to-alternating current (DC_AC) modulation circuit, etc., which are not limited here. The modulation circuit may modulate the electric energy output by the power supply to adapt to the power consumption requirements of the load.

[0037] The target switch 1202 may include a single-pole single-throw switch, a single-pole multi-throw switch (e.g., a single-pole double-throw switch), etc., which is not limited here. The target switch is used to open or close the path between the power supply unit 1201 and the signal transmission unit 1203. Optionally, the target switch 1202 may be a VCC Switch switch, which is not limited here.

[0038] The signal transmission unit 1203 may include various units with signal transmission capabilities. Optionally, the signal transmission unit may have signal transceiver capabilities and / or signal power amplification capabilities, etc., which are not limited here.

[0039] In the related art, the power supply unit 1201 usually provides the operating voltage for the signal transmission unit 1203. The related art usually adopts the target power supply control logic of "ASM_COMMON_ON" and "ASM_COMMON_OFF", and the target power supply control logic is: when the power supply unit 1201 is powered on, the target switch 1202 will switch the conduction state as the signal transmission and reception path of the signal transmission unit 1203 is switched.

[0040] Exemplarily: ...the target switch 1202 switches to the on state—the signal transmission unit 1203 receives the signal—the signal transmission unit 1203 sends the signal—the target switch 1202 switches to the off state….

[0041] It is found in practice that when the power supply unit 1201 is in the power-on state, if the target switch 1202 is switched, it will cause a rapid voltage change in the path between the power supply unit 1201 and the signal transmission unit 1203 (for example: a voltage change rate of 0.16us or 0.18us). When the output voltage in the path is high, if the voltage changes rapidly, it will cause overcurrent in the path, which may cause the path to short-circuit or even burn out the electronic equipment.

[0042] In this regard, the embodiment of the present application provides a power supply method to solve the technical defects in the related art. Optionally, the method can be applied to the above-mentioned electronic device, specifically to the target processor of the electronic device, which is not limited here.

[0043] Optionally, the electronic device can first control the target switch to switch to the on state, and then control the power supply unit to power on when the target switch is in the on state; since the target switch is controlled to switch to the on state before the power supply unit is powered on, that is, there is no voltage on the path between the power supply unit and the signal transmission unit when the target switch is switched, thereby avoiding the voltage in the path changing rapidly during the switching of the target switch, thereby avoiding overcurrent; in addition, after the target switch is switched to the on state, it will remain in the on state during the switching of the signal transceiver path of the signal transmission unit, that is, the target switch will no longer switch to the on state as the signal transceiver path of the signal transmission unit switches, thereby further avoiding overcurrent caused by switching of the target switch, thereby improving the power supply safety of the electronic device.

[0044] Based on this, the power supply method and device, electronic device, and computer-readable storage medium disclosed in the embodiments of the present application are introduced below.

[0045] See also Figure 2 , Figure 2 1 is a flow chart of a power supply method disclosed in an embodiment of the present application. Optionally, the method can be applied to the above-mentioned electronic device, and specifically can be applied to a target processor of the electronic device, which is not limited here. Optionally, the method can include the following steps:

[0046] 202. Control the target switch to switch to an on state.

[0047] In the embodiment of the present application, the target switch may include an on state and an off state. When the target switch is in the on state, the path between the power supply unit and the signal transmission unit is conducted. Optionally, when the target switch is switched to the off state, the path between the power supply unit and the signal transmission unit is disconnected.

[0048] As an optional implementation, the electronic device can control the target switch to switch to the on state when the power supply unit is not powered on and ensures that no voltage is applied to the path between the power supply unit and the signal transmission unit, thereby avoiding the voltage in the path changing rapidly during the switching of the target switch, thereby preventing overcurrent.

[0049] Optionally, the electronic device may determine whether the power supply unit is in a powered-on state; if the power supply unit is in a powered-on state, the electronic device may first control the power supply unit to power off, and then control the target switch to switch to an on state.

[0050] By implementing the above method, the electronic device can detect the power-on state of the power supply unit before switching the conduction state of the target switch to ensure that the conduction state of the target switch is switched only when the power supply unit is not powered on, so as to avoid as much as possible the voltage in the path changing rapidly during the switching process of the target switch, thereby generating overcurrent.

[0051] 204. When the target switch is in the on state, control the power supply unit to power on so that the power supply unit supplies power to the signal transmission unit through the on path, and keep the target switch in the on state during the switching of the signal receiving and transmitting path of the signal transmission unit.

[0052] In the embodiment of the present application, the power supply unit may include a power supply and a modulation circuit, which have been introduced in the previous text and will not be repeated here. Optionally, controlling the power supply unit to power on may refer to: controlling the power supply to supply power to the modulation circuit so that the modulation circuit modulates the electric energy provided by the power supply and supplies power to the signal transmission unit through the conductive path.

[0053] In the embodiment of the present application, the signal transmission unit can transmit and receive communication signals. The signal transmission unit's signal transmission and reception path switching period may include: switching from a receiving signal state to a sending signal state; or switching from a sending signal state to a receiving signal state, which is not limited here.

[0054] It should be noted that in the related art, due to the use of the target power supply control logic introduced above, the target switch will switch the on state as the signal transceiver path of the signal transmission unit is switched. Once the target switch switches the on state, it will cause the path to undergo rapid voltage changes, which may cause overcurrent in the path. Optionally, in an embodiment of the present application, during the switching of the signal transceiver path of the signal transmission unit, the electronic device can control the target switch to remain in the on state and not switch the target switch, so as to avoid rapid changes in voltage in the path, thereby preventing overcurrent, and further improving the power supply safety of the electronic device.

[0055] By implementing the methods disclosed in the above embodiments, the electronic device can first control the target switch to switch to the on state, and then control the power supply unit to power on when the target switch is in the on state; since the target switch is controlled to switch to the on state before the power supply unit is powered on, that is, there is no voltage on the path between the power supply unit and the signal transmission unit when the target switch is switched, thereby avoiding the situation where the voltage in the path changes rapidly during the switching of the target switch, thereby generating an overcurrent; in addition, after the target switch is switched to the on state, it will remain in the on state during the switching of the signal receiving and transmitting path of the signal transmission unit, thereby further avoiding the overcurrent caused by the switching of the target switch, thereby improving the power supply safety of the electronic device.

[0056] See also Figure 3 , Figure 3 1 is a flow chart of another power supply method disclosed in an embodiment of the present application. Optionally, the method can be applied to the above-mentioned electronic device, and specifically can be applied to the target processor of the electronic device, which is not limited here. Optionally, the method can include the following steps:

[0057] 302. Control the target switch to switch to an on state.

[0058] 304. When the target switch is in the on state, control the power supply unit to power on so that the power supply unit supplies power to the signal transmission unit through the on path, and keep the target switch in the on state during the switching of the signal receiving and transmitting path of the signal transmission unit.

[0059] 306. Control the power supply unit to be powered off; when the power supply unit is powered off, control the target switch to switch from the on state to the off state.

[0060] In the embodiment of the present application, when the electronic device controls the power supply unit to be powered on so that the power supply unit supplies power to the signal transmission unit through the conductive path, if the target switch is directly controlled to switch from the conductive state to the disconnected state, the path between the power supply unit and the signal transmission unit will be disconnected instantly, which will also cause the voltage in the path to change rapidly, thereby generating an overcurrent situation.

[0061] Optionally, the electronic device can first control the power supply unit to power off, so that no voltage is applied to the path between the power supply unit and the signal transmission unit. Furthermore, when the power supply unit is powered off, the target switch is controlled to switch from the on state to the off state, so as to avoid the voltage in the path changing rapidly and thus generating overcurrent. At the same time, such control logic will not affect the original function of the electronic device, thus ensuring the normal operation of the electronic device.

[0062] Optionally, the electronic device may control the power supply unit to power off when detecting that the signal transmission unit is switched to the off state, and when the power supply unit is powered off, control the target switch to switch from the on state to the off state.

[0063] The closed state may refer to a state in which the signal transmission unit completes all work tasks. Optionally, the closed state may refer to a state in which the signal transmission unit receives a close instruction and stops all work tasks, which is not limited here.

[0064] It is understandable that when the signal transmission unit is switched to the off state, the signal transmission unit no longer needs power. In order to reduce power consumption and better manage the power supply of the power supply unit, the electronic device can control the power supply unit to power off.

[0065] By implementing the above method, the electronic device can control the power supply unit to power off when the signal transmission unit is switched to the off state, so as to reduce power consumption and improve the battery life of the electronic device; in addition, by first controlling the power supply unit to power off and then controlling the target switch to switch from the on state to the off state, it is also possible to avoid rapid changes in voltage in the path and thus avoid overcurrent.

[0066] In another optional implementation, the electronic device may control the power supply unit to power off when a switching instruction to switch the on state of the target switch is detected, and when the power supply unit is powered off, control the target switch to switch from the on state to the off state.

[0067] Optionally, the switching instruction for switching the conduction state of the target switch may include: a switching instruction for instructing the target switch to switch to an off state, or other switching instructions for instructing the target switch to switch to other conduction states.

[0068] It is understandable that executing the switching instruction will cause the target switch to switch to the off state, or switch to the off state briefly, which will cause the voltage in the path to change rapidly, thereby causing an overcurrent condition.

[0069] Optionally, the electronic device can control the power supply unit to power off in advance when a switching instruction to switch the conduction state of the target switch is detected and the target switch has not yet switched according to the switching instruction; then, when the power supply unit is powered off, it can be switched according to the switching instruction.

[0070] By implementing the above method, the electronic device can detect that the target switch may be about to switch to the on state, and control the power supply unit to power off in advance, thereby avoiding the situation where the target switch switches to the on state when the power supply unit is powered on, causing the voltage in the path to change rapidly, thereby generating overcurrent.

[0071] In another optional implementation, the electronic device may control the power supply unit to power off when a shutdown command for the electronic device is detected, and when the power supply unit is powered off, control the target switch to switch from the on state to the off state.

[0072] It is understandable that the shutdown command for the electronic device will cause all modules in the electronic device to switch to the shutdown state, including the communication module described above. In the related art, there is no strict restriction on the shutdown order of each unit in the communication module. It may be to disconnect the target switch first and then control the power supply unit to power off. This control order of powering off the power supply unit later may cause the voltage in the path to change rapidly when the target switch is switched, thereby generating an overcurrent situation.

[0073] By implementing the above method, when the electronic device detects a shutdown command, it can strictly control the power supply unit to power off first, and then control the target switch to switch from the on state to the off state, thereby avoiding rapid changes in voltage in the path and subsequent overcurrent. At the same time, such control logic will not affect the original function of the electronic device, thereby ensuring the normal operation of the electronic device.

[0074] By implementing the methods disclosed in the above embodiments, the electronic device can control the target switch to switch to the on state before the power supply unit is powered on, so as to avoid the voltage in the path changing rapidly when the target switch is switched to the on state, thereby preventing overcurrent from occurring; in addition, during the switching of the signal receiving and transmitting path of the signal transmission unit, the target switch is controlled to remain in the on state, so as to further avoid overcurrent caused by switching of the target switch;

[0075] Furthermore, when the power supply unit is powered off, the target switch can be controlled to switch from the on state to the off state, thereby avoiding the rapid change of voltage in the path and the generation of overcurrent. At the same time, such control logic will not affect the original function of the electronic device, thus ensuring the normal operation of the electronic device;

[0076] Furthermore, when the signal transmission unit is switched to the off state, the power supply unit can be controlled to be powered off, so as to reduce power consumption and improve the battery life of the electronic device; in addition, by first controlling the power supply unit to be powered off and then controlling the target switch to switch from the on state to the off state, it is also possible to avoid the voltage in the path changing rapidly and thus generating overcurrent;

[0077] Furthermore, when it is detected that the target switch is about to switch to the on state, the power supply unit is controlled to be powered off in advance, thereby avoiding the situation where the voltage in the path changes rapidly due to the switching of the on state of the target switch when the power supply unit is powered on, thereby generating overcurrent;

[0078] Also, when a shutdown command is detected, the power supply unit can be strictly controlled to be powered off first, and then the target switch can be controlled to switch from the on state to the off state, thereby avoiding rapid changes in voltage in the path and resulting in overcurrent. At the same time, such control logic will not affect the original function of the electronic equipment, thereby ensuring the normal operation of the electronic equipment.

[0079] In order to more clearly introduce the power supply method disclosed in the embodiment of the present application. Figure 4 See Figure 4 , Figure 4 This is a schematic diagram of a process disclosed in the embodiment of this application.

[0080] The electronic device can first control the target switch to switch to the on state; then the electronic device can control the power supply to be powered on, so that the power supply unit supplies power to the signal transmission unit through the conductive path; then the signal transmission unit can start working, until the signal transmission unit finishes working, the target switch does not switch, and maintains the previous on state.

[0081] Furthermore, when the signal transmission unit finishes working, the electronic device first controls the power supply unit to power off; and further, when the power supply unit is powered off, the control target switch can be switched from the on state to the off state.

[0082] By implementing the above method, the electronic device can control the target switch to switch to the on state before the power supply unit is powered on, so as to avoid the voltage in the path changing rapidly and causing overcurrent when the target switch is switched to the on state; in addition, during the switching of the signal receiving and transmitting path of the signal transmission unit, the target switch is controlled to remain in the on state, which can further avoid the overcurrent caused by the switching of the target switch; and when the power supply unit is powered off, the target switch can be controlled to switch from the on state to the off state, so as to avoid the voltage in the path changing rapidly and causing overcurrent. At the same time, such control logic will not affect the electronic device to realize the original function, thereby ensuring the normal operation of the electronic device.

[0083] See also Figure 5 , Figure 5 1 is a flow chart of another power supply method disclosed in an embodiment of the present application. Optionally, the method can be applied to the above-mentioned electronic device, and specifically can be applied to the target processor of the electronic device, which is not limited here. Optionally, the method can include the following steps:

[0084] 502. Control the target switch to switch to a first conducting state to conduct a path between the first power supply unit and the signal transmission unit.

[0085] In the embodiment of the present application, the electronic device may execute step 506 after executing step 502.

[0086] 504. Control the target switch to switch to a second conducting state to conduct a path between the second power supply unit and the signal transmission unit.

[0087] In the embodiment of the present application, the electronic device may execute step 506 after executing step 504.

[0088] Optionally, the power supply unit may include a first power supply unit and a second power supply unit, and the target switch may include a first conduction state and a second conduction state.

[0089] For example, see Figure 6 , Figure 6 6 is a schematic diagram of a structure of a signal transmission unit disclosed in an embodiment of the present application. Optionally, the power supply unit may include a first power supply unit 610 and a second power supply unit 620, wherein the first power supply unit 610 and the second power supply unit 620 use a "DC-DC" modulation unit as an example only for the convenience of description and should not be construed as limiting the embodiments of the present application.

[0090] Optionally, the target switch 1202 can be a single-pole double-throw switch, wherein the first conduction state can be a path 630 between the first power supply unit 610 and the signal transmission unit 1203 ; the second conduction state can be a path 640 between the second power supply unit 620 and the signal transmission unit 1203 .

[0091] Optionally, if the target switch 1202 is switched to a high impedance state, that is, the target switch 1202 is not connected to any contact, then the target switch 1202 is in an open state.

[0092] Please refer again Figure 6 In an optional embodiment, the signal transmission unit 1203 may include: a first power amplifier 650, the first power amplifier 650 is used to amplify the power of the signal. Optionally, the first power amplifier 650 may include a first port 6501, the first port 6501 corresponds to the signal power amplification of the first frequency band.

[0093] Optionally, the first conducting state may be that a path 630 between the first power supply unit 610 and the first port 6501 of the first power amplifier 650 is conducting;

[0094] The second conducting state may be that the path 640 between the second power supply unit 620 and the first port 6501 of the first power amplifier 650 is conducting.

[0095] By implementing the above method, when the target switch is switched to different conduction states, the signal transmission unit can be powered by different power supply units, thereby improving the diversity and compatibility of power supply methods for the signal transmission unit, thereby meeting the power supply requirements of the signal transmission unit in different usage scenarios.

[0096] In another optional embodiment, the first power amplifier 650 may also include a second port 6502, which amplifies the signal power corresponding to the second frequency band, and the frequency corresponding to the second frequency band may be lower than the frequency corresponding to the first frequency band; the second port 6502 may be electrically connected to the first power supply unit 610.

[0097] Optionally, the first frequency band may be a high band (High Band, HB), and the second frequency band may be a medium band (Medium Band, MB); or the first frequency band may be a high band (High Band, HB), and the second frequency band may be a low band (Low Band, LB), etc. Figure 6 This should not be construed as limiting the embodiments of the present application.

[0098] Among them, since the second port 6502 of the first power amplifier 650 is directly electrically connected to the first power supply unit 610, the first power supply unit 610 can directly supply power to the second port 6502 to achieve signal power amplification in the second frequency band. When the target switch 1202 is switched to the first conduction state, the path 630 between the first power supply unit 610 and the first port 6501 of the first power amplifier 650 is turned on, then the first power supply unit 610 can supply power to the first port 6501 to achieve signal power amplification in the first frequency band.

[0099] In the embodiment of the present application, the first power supply unit 610 only supports supplying power to either the first port 6501 or the second port 6502; in this regard, when the target switch 1202 is switched to the first on state, the first power supply unit 610 can supply power to the first port 6501 or the second port 6502 of the first power amplifier 650, thereby amplifying the signal power of the first frequency band or the signal power of the second frequency band, thereby realizing the "single call mode", which is a mode that supports one call service.

[0100] Optionally, when the target switch 1202 switches to the second conduction state and the path 640 between the second power supply unit 620 and the first port 6501 of the first power amplifier 650 is turned on, the second power supply unit 620 can supply power to the first port 6501 to achieve signal power amplification in the first frequency band; at the same time, the first power supply unit 610 can supply power to the second port 6502 of the first power amplifier 650 to achieve signal power amplification in the second frequency band.

[0101] For this purpose, the signal power amplification of the first frequency band and the signal power amplification of the second frequency band can be realized simultaneously; thus, the "multi-call mode" can be realized, and the "multi-call mode" is a mode that supports at least two call services.

[0102] By implementing the above method, the conduction state of the target switch can be switched to achieve single-band signal transmission or multi-band signal transmission, thereby realizing the "dual-card dual-pass" function, that is, being able to support multiple call services, thereby enriching the communication scenarios of the communication module and improving the communication flexibility of the communication module.

When the target switch is in the on state, control the power supply unit to power on so that the power supply unit supplies power to the signal transmission unit through the on path, and keep the target switch in the on state during the switching of the signal receiving and transmitting path of the signal transmission unit.

In addition, during the switching of the signal receiving and transmitting path of the signal transmission unit, the target switch is controlled to remain in the on state, so as to further avoid overcurrent caused by switching of the target switch. Furthermore, when the target switch is switched to different on states, the signal transmission unit can be powered by different power supply units, thereby improving the diversity and compatibility of the power supply methods for the signal transmission unit, thereby meeting the power supply requirements of the signal transmission unit in different usage scenarios. demand; and, by switching the conduction state of the target switch, single-band signal transmission or multi-band signal transmission can be achieved, thereby realizing the function of "dual-card dual-pass", that is, it can support a variety of call services, thereby enriching the communication scenarios of the communication module and improving the communication flexibility of the communication module; and, adding a second power amplifier, so that the signal transmission unit can achieve signal power amplification of more frequency bands, thereby enriching the communication scenarios of the communication module and improving the compatibility and flexibility of the communication module; and, according to the currently required target communication mode, the corresponding control target switch can be switched to the corresponding conduction state, so that the communication module matches the current target communication mode, thereby improving the communication effect.

[0117] A first control unit 702, used to control the target switch to switch to a conducting state;

[0118] The second control unit 704 is used to control the power supply unit to power on when the target switch is in the on state, so that the power supply unit supplies power to the signal transmission unit through the on path, and keep the target switch in the on state during the switching of the signal receiving and transmitting path of the signal transmission unit.

[0119] By implementing the above device, the electronic device can first control the target switch to switch to the on state, and then control the power supply unit to power on when the target switch is in the on state; since the target switch is controlled to switch to the on state before the power supply unit is powered on, that is, there is no voltage on the path between the power supply unit and the signal transmission unit when the target switch is switched, thereby avoiding the voltage in the path changing rapidly during the switching of the target switch, thereby avoiding the situation of overcurrent; in addition, after the target switch is switched to the on state, it will still remain in the on state during the switching of the signal receiving and transmitting path of the signal transmission unit, thereby further avoiding the overcurrent caused by the switching of the target switch, thereby improving the power supply safety of the electronic device.

At the same time, such control logic will not affect the electronic device to achieve the original function, thereby ensuring the normal operation of the electronic device.

[0130] The target switch is controlled to switch to a second conducting state to conduct a path between the second power supply unit and the signal transmission unit.

[0131] By implementing the above device, when the target switch is switched to different conduction states, the signal transmission unit can be powered by different power supply units, thereby improving the diversity and compatibility of power supply methods for the signal transmission unit, thereby meeting the power supply requirements of the signal transmission unit in different usage scenarios.

[0134] The second conducting state is that a path between the second power supply unit and the first port of the first power amplifier is conducting.

[0137] By implementing the above-mentioned device, single-band signal transmission or multi-band signal transmission can be achieved by switching the conduction state of the target switch, thereby realizing the "dual-card dual-pass" function, that is, being able to support multiple call services, thereby enriching the communication scenarios of the communication module and improving the communication flexibility of the communication module.
