TECHNICAL FIELD

[0001] The present application relates to the technical field of power consumption control, in particular to an earphone end ultra-low power consumption control method and system. BACKGROUND

[0002] In order to ensure the comfort and portability, the volume and weight of wireless earphones and their charging boxes are usually small, and accordingly, the battery capacity of the built-in batteries in them is also small. The built-in battery of the wireless earphone can generally only maintain operation for a few hours, and the built-in battery of the charging box can generally provide the wireless earphone with two charging times. Even if the wireless earphone is in an idle or dormant state, it will also maintain a low running current.

[0003] Since the wireless earphone needs to be tested before leaving the factory, a certain amount of electricity will be charged during the test. Therefore, the wireless earphone will always be in a low-power running state during the transportation and storage process after packaging and leaving the factory. If the transportation or storage time is too long, the built-in battery may be over-discharged due to continuous power consumption, affecting the endurance and life of the built-in battery. In addition, the wireless earphone may also have over-discharge problems when it is left idle for too long or lost and found.

[0004] Therefore, the shipping mode is developed today, which can make the wireless earphone standby at an extremely low current of less than 1uA, thereby greatly extending the endurance time of the built-in battery and avoiding over-discharge. However, the design of the existing shipping mode is not very reasonable. Either the user needs to manually turn it on, or the self-starting logic is too harsh, and the built-in battery has already consumed a high amount of power when entering the shipping mode. SUMMARY

[0005] The first aspect of the embodiment of the present application discloses an earphone end ultra-low power consumption control method, which specifically comprises: monitoring power consumption parameters and analyzing to obtain a power consumption state; predicting a power consumption trend based on connection history records and signal environment; setting a state control plan based on the power consumption state and the power consumption trend.

[0008] As an optional implementation, the prediction of the power consumption trend based on the connection history and the signal environment comprises: searching for a matching between the connection history and the signal environment to detect whether there is a device to be connected; if the device to be connected is detected, a start-up period of the device to be connected is predicted; the power consumption trend is predicted for the device to be connected and the start-up period thereof.

[0009] As an optional implementation, the setting of the state control plan based on the power consumption state and the power consumption trend comprises: the power consumption trend is used to interfere with the power consumption curve of the earphone to obtain a predicted power consumption curve; a control point is calibrated for the predicted power consumption curve; a time node for controlling the standby state is preset based on the control point.

[0010] As an optional implementation, the method further comprises: the number of the control points is at least two, and at least three standby states are calibrated.

[0011] As an optional implementation, the standby current values of different standby states are different; wherein, in the standby state with the lowest standby current value, only the external power supply is used to trigger the wake-up.

[0012] As an optional implementation, the method further comprises: an RTC timer is set to perform a timed wake-up, and whether the earphone is in an earphone case is detected when the timed wake-up is performed; if it is detected that the earphone is not in the earphone case, the earphone is controlled to enter another standby state with a lower standby current value, an RTC timer is set to perform a timed wake-up, and whether the earphone is in an earphone case is detected when the timed wake-up is performed; if it is detected that the earphone is not in the earphone case, the earphone is controlled to enter another standby state with a lower standby current value.

[0013] As an optional implementation, the method further comprises: the RTC timer is further used to detect a historical connection instruction when the wake-up is performed; if the historical connection instruction is empty, the RTC wake-up mechanism is reset or incrementally updated.

[0014] The second aspect of the embodiment of the application discloses an earphone-end ultra-low-power consumption control system, which comprises: a detection unit is used to monitor a power consumption parameter and analyze an obtained power consumption state; an analysis unit configured to predict an electricity consumption trend based on the connection history and the signal environment; a regulation unit configured to set a state regulation plan based on the electricity consumption state and the electricity consumption trend.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0019] It should be noted that the terms "first", "second", "third", "fourth" and the like in the specification and claims of the present application are used to distinguish different objects, and are not used to describe a specific order. The terms "include" and "have" in the embodiments of the present application and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units need not be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to the process, method, product or device.

[0020] Embodiment one Please refer to Figure 1 For example, Figure 1As shown, the earphone end ultra-low power consumption control method disclosed by the embodiment of the application comprises the following steps: 101, monitor the power consumption parameters, and analyze the power consumption state.

[0021] In this embodiment, the power consumption parameters at least include the earphone battery capacity, the current earphone current value, the earphone power consumption logic, and the charging bin battery capacity.

[0022] Here, the earphone battery capacity, combined with the current earphone current value and the earphone power consumption logic, can intuitively measure the endurance time of the earphone.

[0023] The charging bin battery capacity is used to supply the earphone battery capacity, so when measuring the endurance time of the wireless earphone, the charging bin battery capacity should be considered.

[0024] As an optional implementation, based on the current earphone current value and the earphone power consumption logic, the earphone power consumption curve is predicted. Based on the earphone battery capacity, the charging bin battery capacity and the earphone power consumption curve, the limit endurance curve is generated.

[0025] Here, the earphone power consumption curve is used to intuitively represent the change of the earphone battery capacity with time, and then after considering the charging bin battery capacity, the limit endurance curve for measuring the limit endurance of the wireless earphone can be obtained.

[0026] It can be understood that different brands of wireless earphones have different standby strategies. For a wireless earphone, it may be in a connected state when it is placed outside the charging bin, or it may be in an unconnected state. When it is in an unconnected state, it should regularly poll the connection signal, or send a handshake signal for the audio source device to find. When the wireless earphone is placed in the charging bin for charging, its communication chip may be in an active state, ready to connect with the audio source device after being taken out by the user. In addition, when the wireless earphone is placed in the charging bin for a long time to get data connection, it may be in a sleep state, only the main control chip is running to detect the operation of the user taking it out of the charging bin.

[0027] It can be seen that the earphone power consumption curve and the limit endurance curve are affected by the power and the running time, as well as various connection strategies and sleep strategies, which are not limited here.

[0028] 102, based on the connection history and the signal environment, predict the power consumption trend.

[0029] In this embodiment, the power consumption trend is used to measure the change of the power consumption of the wireless earphone in a specific use environment.

[0030] As an optional implementation, the connection history and the signal environment are searched and matched to detect whether there is a device to be connected. If the to-be-connected device is detected, the activation period of the to-be-connected device is predicted; The power consumption trend is predicted for the to-be-connected device and the activation period thereof.

[0031] Specifically, the signal environment retrieval matching is performed based on the connection history record, which can be used to identify whether the current environment is the daily use environment of the user. For example, if it is measured that the to-be-connected device exists, it can be determined that the user carries the wireless earphone with him / her. At this time, the sound source device is in the to-be-connected state. Then, the activation period of the user using the wireless earphone can be predicted according to the connection history record, and the power consumption data related to the prediction is converted to obtain the power consumption trend.

[0032] On the contrary, if the to-be-connected device is not detected, it can be considered that the wireless earphone is currently in an unfamiliar environment and is separated from the user, or if the connection history record is empty, it can be considered that the wireless earphone has not been used. Obviously, at this time, there is no expectation that the wireless earphone is connected and used. At this time, the power consumption of the wireless earphone should be reduced.

[0033] 103. Based on the power consumption state and the power consumption trend, a state regulation plan is set.

[0034] In this embodiment, after the power consumption state of the wireless earphone and the power consumption trend of the wireless earphone in the subsequent time are known, the running or standby state thereof can be regulated accordingly.

[0035] As an optional implementation, the power consumption trend is used to interfere with the earphone power consumption curve to obtain a predicted power consumption curve; The regulation mark points are calibrated for the predicted power consumption curve; Based on the regulation mark points, the time nodes for regulating the standby state are preset.

[0036] Here, the predicted power consumption curve is used to indicate the expected power consumption state of the wireless earphone, so that the regulation mark points can be calibrated thereon to indicate the earphone power at different stages.

[0037] For example, if the earphone has established a transmission channel and is performing data transmission, the current power consumption level is maintained, and only in necessary cases (such as when the earphone power is lower than 20%), a power reminder is output. If the earphone has established a transmission channel but is not performing data transmission, the power consumption level is adjusted at the preset time nodes according to the power consumption curve and the regulation mark points. For example, after 15 minutes of stopping data transmission, the power consumption level adjustment is triggered to make the earphone enter a standby state with a lower power consumption level. Then, at the next preset time node, if the earphone is still not activated, the power consumption level thereof is reduced again. Through progressive adjustment, the earphone enters a shipping mode with the lowest power consumption.

[0038] For example, the control points can be calibrated for 50% earphone power. When the earphone power is not less than 50%, the wireless earphone is in a signal polling state and is always ready to establish a data connection with the sound source device. When the earphone power is less than 50%, the sleep mechanism of the wireless earphone is triggered, and then the control points can be calibrated for 25% earphone power. When the earphone power is less than 25%, the wireless earphone enters a shipping state to run at a very low power consumption, ensuring that the battery health is not affected by over-discharge.

[0039] As another optional implementation, the number of control points is at least two, for calibrating at least three standby states.

[0040] The standby current values of different standby states are different. In the standby state with the lowest standby current value, only external power supply is used to trigger wake-up.

[0041] Specifically, different brands and types of wireless earphones should have different standby states, and then have different numbers and positions of control points.

[0042] The most significant difference between different standby states is the standby current value. When the wireless earphone is in a signal polling state, the running current can be 50mA, when in a sleep state, the running current can be 50uA, and when in a shipping state, the running current can be 50uA. Thus, compared with the standby state with higher power consumption, the standby time can be increased by tens of times, effectively avoiding over-discharge of the built-in battery, which affects the battery health.

[0043] As another optional implementation, an RTC timer is provided to perform timed wake-up, and to detect whether the earphone is in the earphone case when the timed wake-up is performed. If it is detected that the earphone is not in the earphone case, the earphone is controlled to enter another standby state with a lower standby current value.

[0044] Generally, the existing earphones usually turn off the RTC timer in the standby state, and only wake up when external charging is obtained.

[0045] In this way, the RTC timer is maintained by a low-frequency source (for example, 32KHz), and a wake-up time length (for example, 60 minutes) is set, so that every 60 minutes, the earphone state is detected to determine whether the earphone is placed in the earphone box. If the earphone is still in a state of being separated from the earphone box, the earphone is controlled to enter a standby state with a lower standby current value. In the next wake-up detection, if it is detected that the earphone is still in a state of being separated from the earphone box, the earphone is controlled to enter another standby state with a lower standby current value. This process is repeated until the earphone enters a shipping mode with the lowest power consumption. At this time, the running current of the earphone is usually at the level of 50μA. Compared with the existing sleep mode, longer standby endurance can be achieved, and the earphone is maintained in a state that can be awakened by a connection signal and automatically started without waiting for external charging to wake up. The starting logic is more reasonable and meets the user's usage requirements.

[0046] As another optional implementation, the RTC timer is also used to detect a historical connection instruction when waking up. If the historical connection instruction is empty, the RTC wake-up mechanism is reset or incrementally updated.

[0047] In this way, in the shipping state, the wireless earphone is only powered to the RTC chip to maintain the RTC timing wake-up mechanism. In the case that the earphone is automatically woken up and no connection is obtained, the interval of automatic wake-up is further increased, and the standby endurance is further improved.

[0048] As can be seen, according to the monitored power and use environment, the subsequent power consumption is predicted, and then the state control plan is dynamically set according to the prediction result, so that the standby state is automatically converted without the need for the user to manually start the shipping mode. The earphone state and power consumption are maintained in a reasonable range, and the standby endurance is greatly improved.

[0049] Embodiment Two Please refer to Figure 2 . As shown in Figure 2 , a super-low-power control system of an earphone end can include: A detection unit is used to monitor power consumption parameters and analyze power consumption states. An analysis unit is used to predict power consumption trends based on connection history records and signal environments. A control unit is used to set a state control plan based on power consumption states and power consumption trends.

[0050] In this embodiment, the state control plan of the wireless earphone is determined based on the monitored power consumption state and the predicted power consumption trend of the environment, to ensure that the wireless earphone improves the endurance without affecting the user's connection experience.
