Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to an electronic device, a control method and a storage medium. Background Art

[0002] Common electronic devices (such as smartphones, tablets, etc.) are usually equipped with inertial sensors (such as accelerometers, gyroscopes, etc.) to detect the motion state of the electronic device. When users use electronic devices to take pictures or play aiming and shooting games, the electronic devices can control the movement of the camera to perform optical compensation based on the measurement data of the inertial sensors to achieve optical image stabilization.

[0003] However, when the electronic device is in a charging state, if the user uses the electronic device to take pictures, or operates games such as aiming and shooting, the inertial sensor may be interfered with by other modules in the electronic device (such as a charging-related capacitor module), resulting in inaccurate measurement data of the inertial sensor, and further causing the shooting screen or game screen to shake.

[0062] Figure 1 A schematic diagram of an electronic device provided in an embodiment of the present application. Figure 1As shown, the electronic device 100 includes an A+G sensor 101, three capacitor modules, three charging chips and a battery module 102. The A+G sensor 101 refers to an accelerometer (which can be represented by the letter A) and a gyroscope (which can be represented by the letter G). The three capacitor modules include a capacitor module 103, a capacitor module 104 and a capacitor module 105, and the three charging chips include a charging chip 106, a charging chip 107 and a charging chip 108, wherein the capacitor module 103 is connected to the charging chip 106, the capacitor module 104 is connected to the charging chip 107, and the capacitor module 105 is connected to the charging chip 108. The capacitor module 103 is an external capacitor module of the charging chip 106. The capacitor module 104 is an external capacitor module of the charging chip 107. The capacitor module 105 is an external capacitor module of the charging chip 108. The A+G sensor can be integrated into one chip, and the chip, three capacitor modules and three charging chips can be arranged on the same circuit board of the electronic device (such as Figure 1 On the circuit board 109).

[0063] Figure 1 In the embodiment, the charging chip 106 and the charging chip 107 are fast charging chips and can be the same type of charging chips. The charging chip 106 and the charging chip 107 can charge the battery module of the electronic device at the same time, or each can charge the battery module separately. The charging chip 108 is a common charging chip, which has a lower charging efficiency than the fast charging chip and can also be called a slow charging chip. The charging chip 108 can charge the battery module separately.

[0064] In the embodiment of the present application, the charging mode of the electronic device includes a first charging mode and a second charging mode. In the first charging mode, the electronic device can control the charging chip 106 and / or the charging chip 107 to charge the battery module, and the first charging mode can also be called a fast charging mode. In the second charging mode, the electronic device can control the charging chip 108 to charge the battery module, and the second charging mode can also be called a normal charging mode or a fast charging mode.

[0065] The charging chip mentioned above may also be referred to as a charging management module, which is used to receive charging input from a charger.

[0066] The electronic device involved in the embodiments of the present application may be a mobile phone, a tablet computer, a laptop computer, a PDA, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a smart screen, an artificial intelligence (AI) speaker, a headset, a terminal in industrial control, a terminal in self driving, a terminal in remote medical surgery, a terminal in a smart grid, a terminal in transportation safety, a terminal in a smart city, a terminal in a smart home, a personal digital assistant (PDA), etc., and the embodiments of the present application do not impose any limitation on this.

[0067] based on Figure 1 In the electronic device shown, when the electronic device is charged wired or wirelessly, the A+G sensor may be interfered by the capacitor module on the same circuit board.

[0068] In the first charging mode, the charging chip 106 and / or the charging chip 107 charges the battery module, and the charging chip 106 and / or the charging chip 107 will work at a certain switching frequency to control the charging of the battery module. During the charging process, the capacitor module 103 and / or the capacitor module 104 will vibrate, and their vibration will drive the vibration of the circuit board, and then transmit the above vibration to the A+G sensor through the circuit board.

[0069] In the second charging mode, the charging chip 108 charges the battery module, and the charging chip 108 works at a certain switching frequency to control the charging of the battery module. During the charging process, the capacitor module 105 vibrates, and this vibration drives the vibration of the circuit board, and then transmits the above vibration to the A+G sensor through the circuit board.

[0070] Therefore, no matter which of the above charging modes is used, once the vibration frequency of the circuit board is close to the natural frequency of the A+G sensor in a free state, the circuit board will resonate with the A+G sensor, which will cause the amplitude of the data detected by the A+G sensor to increase, affecting the accuracy of data detection, and thus making it impossible to perform accurate optical compensation.

[0071] The A+G sensor will cause inaccurate measurement data under the interference of the above vibrations, which will affect the related functions that rely on these measurement data. For example, when a user takes a photo while the electronic device is charging, if there is the above interference, the photo will show obvious jitter, such as Figure 2 For another example, when a user plays a shooting game while the electronic device is charging, if there is the above interference, the camera in the game screen will drift, such as Figure 3 As shown, it affects the user's aiming operation.

[0072] In this regard, an embodiment of the present application proposes an electronic device, which includes a system chip, an inertial sensor, a charging chip and a battery module. The system chip is configured to detect measurement data of the inertial sensor when the inertial sensor is in a working state and the electronic device is in a charging state. If the measurement data of the inertial sensor is abnormal, the charging chip is instructed to adjust the switching frequency to prevent the inertial sensor from being disturbed by charging and affecting the device functions that rely on these measurement data.

[0073] It should be noted that the electronic device being in a charging state includes the electronic device being in a wired charging state or a wireless charging state, which is not limited in the embodiments of the present application.

[0079] The charging chip 403 is configured to control the charging of the battery module 404. The charging chip 403 can control the charging parameters of the battery module 404, and the charging parameters include charging current and charging voltage.

[0080] In this embodiment, by monitoring the measurement data of the inertial sensor by the system chip and controlling the switching frequency of the charging chip, it is possible to avoid resonance between the inertial sensor and the circuit board of the electronic device when charging, thereby preventing related functions of the electronic device that rely on the measurement data of the inertial sensor.

[0081] In some embodiments, Figure 4 As shown, the inertial sensor 402 includes an acceleration sensor 4021 and a gyro sensor 4022. The acceleration sensor 4021 is configured to measure the acceleration of the electronic device 400 in three axes. The gyro sensor 4022 is configured to measure the angular velocity of the electronic device 400 rotating around the three axes.

[0082] In some embodiments, the acceleration sensor 4021 and the gyroscope sensor 4022 may be disposed on the integrated chip 405, and both the acceleration sensor 4021 and the gyroscope sensor 4022 adopt a micro-electromechanical system structure. The micro-electromechanical system structure is an existing structure, and this embodiment will not describe it in detail.

[0083] For example, Figure 5 This is a schematic diagram of the structure of an integrated chip provided in an embodiment of the present application. Figure 5 As shown, the integrated chip 405 includes an application specific integrated circuit (ASIC) 4051, a first analog-to-digital converter 4052, and a micro-electromechanical system domain (MEMSDomain) 4053. The application specific integrated circuit 4051 is connected to the first analog-to-digital converter 4052, and the first analog-to-digital converter 4052 is connected to the micro-electromechanical system domain 4053. The micro-electromechanical system domain 4053 (which may correspond to Figure 4 The inertial sensor 402 in the embodiment includes a MEMS acceleration sensor 4054 (corresponding to Figure 4 The acceleration sensor 4021) and the MEMS gyro sensor 4055 (corresponding to Figure 4 The first analog-to-digital converter 4052 is connected to the MEMS acceleration sensor 4054 and the MEMS gyroscope sensor 4055 respectively. Figure 4 , the dedicated integrated circuit 4051 is also connected to the system chip 401.

[0084] The first analog-to-digital converter 4052 is configured to receive measurement data from an inertial sensor, such as measurement data from a MEMS acceleration sensor 4054 and measurement data from a MEMS gyroscope sensor 4055, convert the measurement data from the inertial sensor into a digital signal, and transmit the digital signal to the ASIC 4051. The ASIC 4051 is configured to transmit a digital signal to the system chip 401, and the digital signal is used to indicate the measurement data of the inertial sensor.

The system chip 401 can be used to control the charging chip 403 to operate at a certain switching frequency. When the charging chip 403 operates at a certain switching frequency, the capacitor module 406 vibrates at a certain frequency. The vibration frequency of the capacitor module 406 is related to the switching frequency of the charging chip 403. Generally, the greater the switching frequency of the charging chip 403, the greater the vibration frequency of the capacitor module 406; the smaller the switching frequency of the charging chip 403, the smaller the vibration frequency of the capacitor module 406.

[0086] In some embodiments, the capacitor module 406 includes one or more capacitors, such as a CFLY capacitor.

[0087] In some embodiments, Figure 4 As shown, the electronic device 400 further includes a second analog-to-digital converter 407, and the charging chip 403 is connected to the second analog-to-digital converter 407. The second analog-to-digital converter 407 is configured to monitor the switching frequency of the charging chip 403 and report the switching frequency of the charging chip 403 to the system chip 401.

[0088] The electronic device shown in the above embodiment includes only one charging chip, through which the battery module of the electronic device is charged. During the charging process, the system chip monitors the measurement data of the inertial sensor. If the measurement data of the inertial sensor is abnormal, the switching frequency of the charging chip is adjusted to avoid the inertial sensor being disturbed by the vibration of the capacitor module outside the charging chip, so that its measurement data is more accurate.

[0089] Figure 6 Schematic diagram of an electronic device provided in an embodiment of the present application Figure 3 .like Figure 6As shown, the electronic device 600 includes: a system chip 601, an integrated chip 602, a first charging chip 603, a second charging chip 604, a third charging chip 605 and a battery module 612.

[0090] In some embodiments, Figure 6 As shown, the capacitor module of the electronic device includes a first capacitor module 606, a second capacitor module 607 and a third capacitor module 608, the first capacitor module 606 is connected to the first charging chip 603, the second capacitor module 607 is connected to the second charging chip 604, and the third capacitor module 608 is connected to the third charging chip 605.

[0091] In some embodiments, Figure 6 As shown, the second analog-to-digital converter of the electronic device includes a third analog-to-digital converter 609, a fourth analog-to-digital converter 610, and a fifth analog-to-digital converter 611. The third analog-to-digital converter 609 is connected to the first charging chip 603, the fourth analog-to-digital converter 610 is connected to the second charging chip 604, and the fifth analog-to-digital converter 611 is connected to the third charging chip 605.

[0092] The third analog-to-digital converter 609 is configured to monitor the switching frequency of the first charging chip 603, and report the switching frequency of the first charging chip 603 to the system chip. The fourth analog-to-digital converter 610 is configured to monitor the switching frequency of the second charging chip 604, and report the switching frequency of the second charging chip 604 to the system chip. The fifth analog-to-digital converter 611 is configured to monitor the switching frequency of the third charging chip 605, and report the switching frequency of the third charging chip 605 to the system chip.

[0093] The first charging chip 603 and the second charging chip 604 are fast charging chips, and the first charging chip 603 and the second charging chip 604 can be fast charging chips of the same model. The third charging chip 605 is a common charging chip. For example, Figure 6 In the embodiment, the first charging chip 603 is the main charging chip in the first charging mode, and the second charging chip 604 is the auxiliary charging chip in the first charging mode. The third charging chip 605 includes a BUCK circuit and a power management unit (Power Management Unit, PMU).

[0094] In some embodiments, the system chip is configured to control the first charging chip 603 to work in the first charging mode. The first charging chip 603 charges the battery module. In some embodiments, the system chip is configured to control the second charging chip 604 to work in the first charging mode. The second charging chip 604 charges the battery module. In some embodiments, the system chip is configured to control the first charging chip 603 and the second charging chip 604 to work in the first charging mode. The first charging chip 603 and the second charging chip 604 charge the battery module at the same time. The first charging mode is a fast charging mode.

[0095] In some embodiments, the system chip is configured to control the third charging chip 605 to work in the second charging mode. The third charging chip 605 supplies power to the battery module. The second charging mode is a normal charging mode.

[0096] In some embodiments, the integrated chip 602 may include a dedicated integrated circuit 6021, a first analog-to-digital converter 6022, and a micro-electromechanical system domain 6023. Figure 5 The embodiments are not described in detail here.

[0097] Combination Figure 6 In actual applications, when the first charging chip charges the battery module, the A+G sensor on the integrated chip may be disturbed by the vibration of the first capacitor module, resulting in abnormal measurement data of the A+G sensor. When the second charging chip charges the battery module, the A+G sensor on the integrated chip may be disturbed by the vibration of the second capacitor module, resulting in abnormal measurement data of the A+G sensor. When the third charging chip charges the battery module, the A+G sensor on the integrated chip may be disturbed by the vibration of the third capacitor module, resulting in abnormal measurement data of the A+G sensor. When the first charging chip and the second charging chip charge the battery module at the same time, the A+G sensor on the integrated chip may be disturbed by the vibration of the first capacitor module and the second capacitor module, resulting in abnormal measurement data of the A+G sensor.

[0098] No matter which of the above situations occurs, the system chip can execute the control method provided in the embodiment of the present application. By instructing the first charging chip and / or the second charging chip to adjust the switching frequency, or instructing the third charging chip to adjust the switching frequency, the A+G sensor can be prevented from being disturbed by vibration, making its measurement data more accurate.

[0099] Based on the electronic device shown in the aforementioned embodiment, the system chip can monitor the measurement data of the inertial sensor in a charging scenario (wired charging or wireless charging). When the measurement data of the inertial sensor is abnormal, the system chip instructs the charging chip of the electronic device to adjust the switching frequency, thereby avoiding inaccurate measurement data caused by charging interference on the inertial sensor.

[0100] The control method of the electronic device is described in detail below with reference to the accompanying drawings.

[0101] Figure 7 The process of the control method provided in the embodiment of the present application Figure 1 .

[0102] like Figure 7 As shown, the control method includes:

[0103] S701: At a first moment, an inertial sensor of an electronic device is in a working state and the electronic device is in a charging state, and a system chip of the electronic device obtains measurement data of the inertial sensor.

[0104] In some embodiments, the inertial sensor of the electronic device includes an acceleration sensor and a gyroscope sensor. The inertial sensor of the electronic device being in a working state can also be described as the electronic device enabling the inertial sensor. When the inertial sensor is in a working state, its measurement data can be transmitted to the system chip so that the system chip can monitor whether the measurement data is abnormal.

[0105] In some embodiments, the inertial sensor of the electronic device is in a working state, and the electronic device is in a fast charging state, that is, in a first charging mode, and the system chip of the electronic device obtains measurement data of the inertial sensor.

[0106] In some embodiments, the inertial sensor of the electronic device is in a working state, and the electronic device is in a normal charging state, that is, in a second charging mode, and the system chip of the electronic device obtains measurement data of the inertial sensor.

[0107] In some embodiments, the system chip of the electronic device can obtain the measurement data of the inertial sensor in the following manner:

[0108] S7011 . At a first moment, the inertial sensor transmits measurement data of the inertial sensor to a first analog-to-digital converter.

[0109] S7012: The first analog-to-digital converter converts the measurement data of the inertial sensor into a digital signal.

[0110] S7013. The first analog-to-digital converter transmits a digital signal to the application-specific integrated circuit, where the digital signal is used to indicate measurement data of the inertial sensor.

[0111] S7014, the system chip obtains digital signals from the dedicated integrated circuit.

[0112] In this embodiment, the inertial sensor, the first analog-to-digital converter and the dedicated integrated circuit can be integrated on the same chip, such as Figure 5It is understood that the measurement data of the inertial sensor is an analog signal, which can be processed by the first analog-to-digital converter to obtain a digital signal so that the system chip can perform subsequent data processing and analysis.

[0113] When the electronic device is in the charging state, the charging chip works at a certain switching frequency, and the capacitor module connected to the charging chip will vibrate at a certain frequency. This vibration will cause the circuit board to vibrate, and then transmit the vibration to the inertial sensor located on the same circuit board through the circuit board. When the vibration frequency of the circuit board is consistent with the frequency of the inertial sensor in the free state, resonance will occur, which will cause the amplitude of the data detected by the inertial sensor to increase (the measurement data of the inertial sensor is abnormal), affecting the accuracy of data detection. Among them, the inertial sensor in the free state reciprocates along each axis at a fixed frequency. If the user uses the electronic device to take pictures or play games, the frequency of each axis of the inertial sensor will change.

[0114] S702: When the measurement data of the inertial sensor is abnormal, the system chip instructs the charging chip of the electronic device to adjust the switching frequency.

[0115] In some embodiments, the system chip instructs the charging chip to adjust the switching frequency, including: the system chip sends a control instruction to the charging chip. In one example, the control instruction may indicate the switching frequency, and the charging chip adjusts the switching frequency of the charging chip based on the switching frequency indicated in the control instruction. In another example, the control instruction only indicates that the charging chip needs to adjust the switching frequency, and the charging chip can adjust the switching frequency of the charging chip based on the control instruction and a predefined adjustment rule (such as a rule of traversing the adjustment from large to small, or from small to large, etc.).

[0116] In some embodiments, if the measurement data of the acceleration sensor is monitored to be unchanged and the measurement data of the gyroscope sensor is changed, the system chip can determine that the measurement data of the inertial sensor is abnormal, and instruct the charging chip of the electronic device to adjust the switching frequency to make the measurement data of the inertial sensor normal.

[0117] In some embodiments, if the measurement data of the acceleration sensor and the measurement data of the gyroscope sensor are monitored to change, the system chip can determine that the measurement data of the inertial sensor is abnormal, and instruct the charging chip of the electronic device to adjust the switching frequency to make the measurement data of the inertial sensor normal.

[0118] Based on the above two embodiments, the abnormal measurement data of the inertial sensor mainly refers to the abnormal measurement data of the gyroscope sensor. The normal measurement data of the inertial sensor mainly refers to the normal measurement data of the gyroscope sensor. When the electronic device is in a charging state, if the vibration of the capacitor module outside the charging chip causes the gyroscope sensor to resonate, it will cause a large change in the measurement data of the gyroscope sensor, indicating that the gyroscope sensor is disturbed by charging, the measurement data of the gyroscope sensor is abnormal, and the measurement data of the gyroscope is inaccurate. By adjusting the switching frequency of the charging chip of the electronic device, the above resonance can be avoided, so that the measurement data of the gyroscope sensor returns to normal.

[0119] It should be noted that the change of the measurement data of the acceleration sensor is mainly related to the motion state of the electronic device and is usually not affected by charging.

[0120] In this embodiment, the charging chip may be a fast charging chip or a common charging chip.

[0121] In some embodiments, when the measurement data of the inertial sensor is abnormal, the system chip selects a second switching frequency based on the lookup table and instructs the charging chip to adjust the switching frequency to the second switching frequency, wherein the second switching frequency is different from the first switching frequency of the charging chip at the first moment, and the second switching frequency is an available switching frequency.

[0122] In some embodiments, the lookup table includes unavailable switching frequencies for the charging chip.

[0123] In some embodiments, the lookup table includes available switching frequencies for the charging chip.

[0124] In some embodiments, the lookup table includes unavailable switching frequencies and available switching frequencies of the charging chip.

[0125] It should be noted that the available switching frequency refers to the switching frequency of the charging chip that does not cause abnormal measurement data of the inertial sensor when the electronic device is charging. The unavailable switching frequency refers to the switching frequency of the charging chip that causes abnormal measurement data of the inertial sensor when the electronic device is charging. The available switching frequency and the unavailable switching frequency can be determined by testing before the device leaves the factory, and the available switching frequency and / or the unavailable switching frequency can be stored in the device to guide the device to adjust the switching frequency of the system chip when the inertial sensor measurement data is abnormal.

[0126] In some embodiments, the lookup table is stored in a local storage space of the system chip.

[0127] In some embodiments, the lookup table is stored in a memory, which is a memory independent of the system chip.

[0128] The above-mentioned lookup table is preconfigured. Before the electronic device leaves the factory, the tester tests whether the measurement data of the inertial sensor is abnormal at different switching frequencies of the charging chip by traversing the switching frequencies of the charging chip when the electronic device is charged. If the measurement data of the inertial sensor is abnormal at the switching frequency of a certain charging chip, the switching frequency of the charging chip is marked as an unavailable switching frequency. If the measurement data of the inertial sensor is normal at the switching frequency of a certain charging chip, the switching frequency of the charging chip is marked as an available switching frequency. At the same time, the charging efficiency at the switching frequency of the charging chip can be obtained. After the above test, the unavailable switching frequency and / or the available switching frequency of the charging chip can be stored in the lookup table. The available switching frequencies of the charging chip in the lookup table can be stored in order of charging efficiency from high to low. The lookup table is used to guide the system chip to regulate the switching frequency of the charging chip.

[0129] The above-mentioned test process can be executed by the system chip, that is, the system chip executes a preset program code, traverses multiple switching frequencies of the charging chip, monitors whether the measurement data of the inertial sensor is abnormal, and stores the unavailable switching frequency and / or available switching frequency of the charging chip in a lookup table, so as to guide the system chip to control the switching frequency of the charging chip in actual applications.

[0130] It should be noted that in the above embodiment, the switching frequency of the charging chip at the first moment is the first switching frequency, which is the available switching frequency of the charging chip verified by the above test process, and the first switching frequency is usually the switching frequency of the available switching frequencies of the charging chip, which makes the charging efficiency of the charging chip the highest. However, in actual applications, due to the difference between the test environment and the environment actually used by the user, such as in an extremely cold or magnetic field changing environment, the charging chip works at a verified switching frequency, and the system chip may also detect abnormal measurement data of the inertial sensor. At this time, the system chip needs to re-instruct the charging chip to adjust the switching frequency based on the lookup table to avoid charging interference causing inaccurate measurement data of the inertial sensor.

[0131] In some embodiments, the charging chip has multiple switching frequencies, and the system chip selects a second switching frequency based on a lookup table, including: the system chip eliminates the first switching frequency and the unusable switching frequencies of the charging chip in the lookup table from the switching frequencies of the multiple charging chips, and selects the switching frequency that makes the charging chip have the highest charging efficiency as the second switching frequency.

[0132] In some embodiments, after the system chip instructs the charging chip to adjust the switching frequency to the second switching frequency, the system chip obtains the measurement data of the inertial sensor. When the measurement data of the inertial sensor is still abnormal, the system chip re-instructs the charging chip to adjust the switching frequency based on the lookup table until the measurement data of the inertial sensor is normal.

[0133] In one example, the lookup table includes available switching frequencies of the charging chip, and the system chip selects an available switching frequency other than the first switching frequency and the second switching frequency from the available switching frequencies of the charging chip in the lookup table. Specifically, a new available switching frequency can be selected by traversing the available switching frequencies.

[0134] In one example, the lookup table includes unusable switching frequencies of the charging chip, and the system chip should avoid the unusable switching frequencies of the charging chip, the first switching frequency, and the second switching frequency.

[0135] The following is a specific example to illustrate how the system chip re-instructs the switching frequency of the charging chip.

[0136] Exemplarily, the charging chip of the electronic device is a common charging chip, and the lookup table shown in Table 1 includes available switching frequencies and unavailable switching frequencies of the common charging chip, wherein the available switching frequencies are listed in descending order of the charging efficiency of the charging chip. The switching frequencies in Table 1 are only examples.

[0137] Table 1

[0138] Available switching frequencies {800kHz,685kHz,600kHz,532kHz,480kHz,342kHz} Unusable switching frequency {400kHz, 436kHz}

[0139] Based on the above Table 1, if the system chip controls the charging chip to operate at 800kHz at the first moment, if the system chip detects that the measurement data of the inertial sensor is abnormal, based on Table 1, the charging chip is controlled to operate at 685kHz (the second highest switching frequency for charging efficiency), and the measurement data of the inertial sensor continues to be monitored. If the measurement data of the inertial sensor is still abnormal, the charging chip is controlled to operate at 600kHz based on Table 1 until the measurement data of the inertial sensor is normal.

[0140] In some embodiments, the lookup table may include only the available switching frequencies shown in Table 1.

[0141] In some embodiments, the lookup table may only include the unavailable switching frequencies shown in Table 1. When the system chip reselects the switching frequency of the charging chip, it needs to avoid the unavailable switching frequencies of the charging chip in the lookup table.

[0142] In some embodiments, the charging chip of the electronic device is a fast charging chip, and the lookup table includes available switching frequencies and / or unavailable switching frequencies of the fast charging chip, similar to Table 1.

[0143] S703: At the second moment, the inertial sensor is not in a working state, and the electronic device is in a charging state, and the system chip controls the charging chip to operate at a preset switching frequency.

[0144] The inertial sensor not being in a working state may also be described as the electronic device not enabling the inertial sensor. For example, when the electronic device is in a low power mode, the electronic device does not enable the inertial sensor to save power consumption of the device.

[0145] It is understandable that the inertial sensor is not in working state, the inertial sensor does not produce measurement data, the system chip does not receive the measurement data of the inertial sensor, and the functions related to the measurement data are not turned on. At this time, the electronic device is in charging state, and the system chip controls the charging chip to work at a preset switching frequency. Usually, the charging chip works at a preset switching frequency, and its charging efficiency is the highest.

[0146] The first moment and the second moment mentioned above are different moments, and the timing relationship between S701 and S703 is not limited.

[0147] In some embodiments, the control method further includes: adding the switching frequency of the charging chip when the measurement data of the inertial sensor is abnormal to the lookup table to update the unavailable switching frequency in the lookup table.

[0148] Exemplarily, referring to Table 1, assuming that the switching frequency of the charging chip at the first moment is 600kHz, and the measurement data of the inertial sensor at 600kHz is abnormal, the system chip can traverse the available switching frequencies in Table 1 in the following order: 685kHz→800kHz→342kHz→480kHz→532kHz. If the measurement data of the inertial sensor at 685kHz is still abnormal, 685kHz can be added or migrated to the unavailable switching frequency in the lookup table (or, 685kHz can be marked as an unavailable switching frequency). According to the traversal order of the above switching frequencies, when the measurement data of the inertial sensor at a certain switching frequency is not abnormal, the traversal is stopped and the charging chip operates at this switching frequency.

[0149] It should be pointed out that the above switching frequency traversal process is usually completed instantaneously, and users usually do not perceive changes in the device due to inertial sensor abnormalities, such as jitter in the device's shooting screen or game screen.

[0150] An embodiment of the present application shows a control method, in which the system chip monitors the measurement data of the inertial sensor during charging. If the measurement data is abnormal, the system chip can adjust the switching frequency of the charging chip to prevent the inertial sensor from being disturbed by charging and causing inaccurate measurement data, thereby affecting related functions of electronic devices that rely on the inertial sensor measurement data, such as the device's shooting anti-shake function.

[0151] In some embodiments, the charging chip includes a first charging chip, a second charging chip and a third charging chip, and the lookup table includes at least one of the following: when the first charging chip charges a battery module of an electronic device, an unavailable switching frequency of the first charging chip and at least one of the available switching frequencies; or, when the second charging chip charges the battery module, an unavailable switching frequency of the second charging chip and at least one of the available switching frequencies; or, when the third charging chip charges the battery module, an unavailable switching frequency of the third charging chip and at least one of the available switching frequencies; or, when the first charging chip and the second charging chip charge the battery module at the same time, an available switching frequency combination and / or an unavailable switching frequency combination, the available switching frequency combination including an available switching frequency combination of the first charging chip and the second charging chip, and the unavailable switching frequency combination including an unavailable switching frequency combination of the first charging chip and the second charging chip.

[0152] When the first charging chip alone charges the battery module of the electronic device, if the measurement data of the inertial sensor is abnormal, the system chip can adjust the switching frequency of the first charging chip by executing the control method of the aforementioned embodiment. When the second charging chip alone charges the battery module of the electronic device, if the measurement data of the inertial sensor is abnormal, the system chip can adjust the switching frequency of the second charging chip by executing the control method of the aforementioned embodiment. When the third charging chip alone charges the battery module of the electronic device, if the measurement data of the inertial sensor is abnormal, the system chip can adjust the switching frequency of the third charging chip by executing the control method of the aforementioned embodiment.

[0153] The following describes how the system chip executes the control method when the first charging chip and the second charging chip simultaneously charge the charging module of the electronic device if the measurement data of the inertial sensor is abnormal, in conjunction with the accompanying drawings.

[0154] Figure 8 The process of the control method provided in the embodiment of the present application Figure 2 .like Figure 8 As shown, the control method includes:

[0155] S801: At a first moment, an inertial sensor of an electronic device is in a working state, and a first charging chip and a second charging chip of the electronic device are charging a battery module at the same time, and a system chip of the electronic device obtains measurement data of the inertial sensor.

[0156] In this embodiment, the first charging chip and the second charging chip of the electronic device charge the battery module at the same time, which is a charging state of the first charging mode. The first charging chip is connected to the first capacitor module, and the second charging chip is connected to the second capacitor module. When the electronic device is in a charging state, the first charging chip and the second charging chip operate at a certain switching frequency, and the corresponding first capacitor module and the second capacitor module will vibrate at a certain frequency, which will cause the vibration of the circuit board, and then transmit the vibration to the inertial sensor located on the same circuit board through the circuit board. When the vibration frequency of the circuit board is consistent with the frequency of the inertial sensor in a free state, resonance occurs, which will cause the amplitude of the data detected by the inertial sensor to increase, affecting the accuracy of data detection.

[0157] S802: When the measurement data of the inertial sensor is abnormal, the system chip selects a third switching frequency for the second charging chip based on available switching frequency combinations and / or unavailable switching frequency combinations in the lookup table while the switching frequency of the first charging chip remains unchanged.

[0158] In some embodiments, the lookup table includes available switching frequency combinations for the charging chip.

[0159] In some embodiments, the lookup table includes unavailable switching frequency combinations for the charging chip.

[0160] In some embodiments, the lookup table includes available switching frequency combinations and unavailable switching frequency combinations of the charging chip.

[0161] The available switching frequency combination includes an available switching frequency combination of the first charging chip and the switching frequency combination of the second charging chip. The unavailable switching frequency combination includes an unavailable switching frequency combination of the first charging chip and the switching frequency combination of the second charging chip.

[0162] The above lookup table is pre-configured.

[0163] Exemplarily, the first charging chip and the second charging chip can be charging chips of the same model, and the first charging chip and the second charging chip can use the same or different switching frequencies. For example, the switching frequency of the first charging chip or the second charging chip can be any one of the array A {300kHz, 350kHz, 400kHz, 450kHz, 500kHz, 550kHz, 600kHz, 750kHz}. Based on the array A, there are multiple combinations of the switching frequencies of the first charging chip and the second charging chip. It can be understood that different combinations of the switching frequencies of the first charging chip and the second charging chip have different corresponding charging efficiencies.

[0164] Before the electronic equipment leaves the factory, the tester can test whether the measurement data of the inertial sensor is abnormal in different combinations by traversing various combinations. If the measurement data of the inertial sensor is abnormal in a certain combination, the combination is marked as an unusable switching frequency combination of the charging chip. If the measurement data of the inertial sensor is normal in a certain combination, the combination is marked as an available switching frequency combination of the charging chip, and at the same time, the charging efficiency in the combination can be obtained. The available switching frequency combinations of the charging chip in the lookup table can be stored in order from high to low charging efficiency. The lookup table is used to guide the system chip to regulate the first charging chip or the second charging chip.

[0165] The above-mentioned test process can be executed by the system chip, that is, the system chip executes a preset program code, traverses various combinations of the switching frequencies of the first charging chip and the second charging chip, monitors whether the measurement data of the inertial sensor is abnormal, and stores the unusable switching frequency combinations and / or available switching frequency combinations of the charging chip in a lookup table, so as to guide the system chip to regulate the switching frequency of the first charging chip and / or the second charging chip in actual applications.

[0166] Exemplarily, the lookup table shown in Table 2 includes unavailable switching frequency combinations of charging chips. For example, [500kHz, 500kHz] in Table 2 indicates that when the switching frequencies of the first charging chip and the second charging chip are both 500kHz, the measurement data of the inertial sensor is abnormal, and this combination is unavailable. The explanations of other arrays are similar and are all unavailable.

[0167] Table 2

[0168]

[0169] In some embodiments, the lookup table is stored in a local storage space of the system chip.

[0170] In some embodiments, the lookup table is stored in a memory, which is a memory independent of the system chip.

[0171] In some embodiments, the system chip adds the switching frequency combination of the charging chip when the measurement data of the inertial sensor is abnormal to the lookup table to update the lookup table.

[0172] S803: The system chip instructs the second charging chip to adjust the switching frequency to a third switching frequency.

[0173] S804: The system chip obtains measurement data of the inertial sensor.

[0174] S805. When the measurement data of the inertial sensor is still abnormal, while the switching frequency of the first charging chip remains unchanged, the system chip re-instructs the second charging chip to adjust the switching frequency based on the available switching frequency combinations and / or unavailable switching frequency combinations in the lookup table until the measurement data of the inertial sensor is normal.

[0175] For example, assuming that the switching frequency combination of the first charging chip and the second charging chip at the first moment is [500kHz, 500kHz], and the measurement data of the inertial sensor under this switching frequency combination is abnormal, the switching frequency combination can be added to Table 2 to update the unavailable switching frequency combination in the lookup table. At the same time, based on the above array A and Table 2, when the switching frequency of the first charging chip is fixed at 500kHz, avoid the unavailable switching frequency combination in Table 2 and select [500kHz, 750kHz]. If the measurement data of the inertial sensor under the switching frequency combination [500kHz, 750kHz] is still abnormal, the system chip can traverse the switching frequency combination in the following order:

[0176] [500kHz, 300kHz]→[500kHz, 350kHz]→[500kHz, 400kHz]→[500kHz, 450kHz]. If during the traversal process, the measurement data of the inertial sensor under a certain switching frequency combination is not abnormal, the traversal is stopped, so that the first charging chip and the second charging chip work at the switching frequency combination corresponding to the traversal when the traversal is stopped.

[0177] In the above embodiment, under the condition that the switching frequency of the first charging chip is fixed, the switching frequency of the available second charging chips is traversed based on the lookup table to adjust the switching frequency of the second charging chip.

[0178] In some embodiments, the first charging chip is a main charging chip in a first charging mode (fast charging mode), and the second charging chip is an auxiliary charging chip in the first charging mode.

[0179] In some embodiments, when the measurement data of the inertial sensor is abnormal, while the switching frequency of the second charging chip remains unchanged, the system chip selects a fourth switching frequency (not shown) for the first charging chip based on the available switching frequency combinations and / or unavailable switching frequency combinations in the lookup table.

[0180] In the above embodiment, under the condition that the switching frequency of the second charging chip is fixed, the switching frequency of the first charging chip is traversed based on the lookup table to adjust the switching frequency of the first charging chip.

[0181] Based on the aforementioned embodiments, by fixing the switching frequency of one of the two charging chips and traversing the switching frequency of the other charging chip to obtain a suitable switching frequency combination, the measurement data of the inertial sensor is not affected by the vibration of the capacitor module, thereby improving the stability of the device when charging.

[0182] In some embodiments, the control method further comprises:

[0183] S806: If the switching frequency of the first charging chip remains unchanged, after traversing the switching frequencies of all available second charging chips, the measurement data of the inertial sensor is still abnormal, the system chip instructs the first charging chip to adjust the switching frequency.

[0184] S807: When the switching frequency of the first charging chip remains unchanged after adjustment, the system chip re-instructs the second charging chip to adjust the switching frequency based on the available switching frequency combinations and / or unavailable switching frequency combinations in the lookup table until the measurement data of the inertial sensor is normal.

[0185] Exemplarily, referring to the example of S805, if the switching frequency of the first charging chip is fixed (500kHz), and the measurement data of the inertial sensor is still abnormal after traversing to the last switching frequency combination [500kHz, 450kHz], the switching frequency of the first charging chip in the switching frequency combination is adjusted, such as adjusting 500kHz to 550kHz, and obtaining a switching frequency combination of [550kHz, 500kHz]. If the measurement data of the inertial sensor under the switching frequency combination [550kHz, 500kHz] is still abnormal, the system chip keeps the switching frequency of the first charging chip fixed at 550kHz, and based on array A and Table 2, avoids the unavailable switching frequency combination in Table 2, adjusts the switching frequency of the second charging chip, and traverses the switching frequency combination in the following order:

[0186] [550kHz, 600kHz] → [550kHz, 750kHz] → [550kHz, 300kHz] → [550kHz, 350kHz] → [550kHz, 400kHz]. If during the traversal process, the measurement data of the inertial sensor under a certain switching frequency combination is not abnormal, the traversal is stopped, so that the first charging chip and the second charging chip work with the switching frequency combination corresponding to when the traversal is stopped. If the above traversal is completed and the measurement data of the inertial sensor is still abnormal, the switching frequency of the first charging chip can be adjusted again (such as adjusting 550kHz to 600kHz) and fixed, and the switching frequency of the second charging chip can be traversed again until the measurement data of the inertial sensor is normal.

[0187] In some embodiments, the control method further comprises:

[0188] S808. After the system chip instructs the first charging chip or the second charging chip to adjust the switching frequency, the switching frequency combination of the charging chip when the measurement data of the inertial sensor is still abnormal is added to the lookup table to update the lookup table.

[0189] Exemplarily, referring to the example of S805 , the switching frequency combination [500 kHz, 750 kHz] in the traversal process is added to Table 2 to update the lookup table.

[0190] The embodiment of the present application shows a control method, in which the system chip monitors the measurement data of the inertial sensor during charging.

Specifically, the switching frequency of one of the charging chips can be adjusted while keeping the switching frequency of the other charging chip unchanged until the measurement data of the inertial sensor is normal. The above method avoids the inertial sensor being disturbed by charging and causing inaccurate measurement data, which in turn affects the relevant functions of the electronic device that relies on the measurement data of the inertial sensor, such as the device's anti-shake function for shooting.
