Description

Battery power guarantee method and device for portable electronic product and mobile terminal
Technical Field
The present invention relates to portable electronic products, and in particular, to a method, a device and a mobile terminal for guaranteeing battery power of a portable electronic product.
Background
At present, with the rapid development of mobile communication technology, mobile terminal users not only have high requirements on the functions, reliability and operability of mobile phones, but also have higher and higher requirements on the humanized design of mobile phones. This requires the mobile phone designer to consider the user's needs in many ways, and the battery life is one of the design criteria that need to be focused.
The battery is used as the only power supply under the condition that the charger is not connected in the daily use process of most mobile phones, and has great influence on the normal use of the mobile phones. However, due to the bottleneck of battery technology development, the battery capacity of the mobile phone battery is very limited, resulting in a short duration of the mobile phone. As the battery power is gradually consumed until the battery is automatically turned off, the user often cannot operate the mobile phone normally. In order to avoid affecting the implementation of the basic functions of the mobile phone, the user needs to pay attention to the battery power of the mobile phone frequently and charge the mobile phone in time when the battery power is low, so as to avoid the phenomenon that the mobile phone cannot be used due to the exhaustion of the battery power in an important time period as much as possible.
Needless to say, it is not realistic to require the user to pay attention to the battery level at all times. In view of this, the prior art proposes two types of solutions: the basic idea of one kind of solution is to reasonably use and distribute the limited electric quantity of the battery, and when the electric quantity of the battery is detected to be insufficient, the host system enters a power saving mode as soon as possible, so that the electric quantity consumption of the system battery is reduced, the service time of the mobile phone is prolonged, and the purpose of meeting the most important requirements of users is achieved; the basic idea of another kind of solution is that, when the battery power is lower than the set threshold, the low power prompt is performed, so as to remind the user to charge in time, and the battery power is increased through charging, thereby ensuring that the battery can continuously supply power.
The latter solution can predict the approximate available time of a user mobile phone according to the basic available time of the battery and the current using state of the user, so as to guide the user to correctly use the battery, so as not to cause accidents due to insufficient power. The practical effectiveness of such charging schemes is still insufficient: on one hand, although the technical scheme can solve the problem of standby time of the mobile phone concerned by the user, most users rarely pay attention to when the mobile phone is charged when using the mobile phone, and the mobile phone cannot be normally used due to power shortage when the battery is exhausted; on the other hand, even if the user knows how much time the mobile phone can be used, the user rarely calculates precisely how long the mobile phone battery can be used and when the mobile phone battery should be charged, so that the user often mistakenly recognizes that the battery is sufficient and the battery is not charged in time, and finally the battery is exhausted in an important time period, so that the mobile phone cannot be used normally.
Similar to the use condition of a mobile phone battery, other mobile terminals such as a tablet computer, an intelligent game machine, an intelligent navigator, an intelligent remote controller and an intelligent set-top box also have the problems, and all the mobile terminals need to be powered by the battery, and the continuous use time of the mobile terminals is greatly limited along with the gradual consumption of the electric quantity of the battery until the mobile terminals are automatically turned off. The prior art proposes some battery charging schemes, but none of them can fully satisfy the user's needs. Therefore, how to overcome the above-mentioned defects in the system, in whole or in part, becomes an urgent problem to be solved.

Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Referring to fig. 1, a flowchart of a battery level guarantee method according to an embodiment of the invention is shown. The embodiment aims to calculate whether the current electric quantity of the battery can persist to the set time, and if not, the charging is prompted, and the basic process is as follows: detecting the current battery capacity of the system (step S110), analyzing the battery capacity available time (step S120), and then determining whether the battery capacity available time is less than a desired battery usage time, if so, sending a capacity maintenance prompt message (step S130-step S140) so as to prompt a user to charge, save power or take other capacity guarantee measures in time according to the charge prompt signal; if not, the current battery capacity of the system continues to be detected until the usable time of the battery capacity is less than the expected battery use time, and then charging and/or power saving is prompted according to the method shown in the step S130 to the step S140. The method for guaranteeing battery power of the portable electronic product according to the embodiment is further described with reference to fig. 1.
The method starts in step S110, where step S110 is used to detect the current battery level of the system. The current battery capacity of the system can be visually displayed in the forms of percentage, filling grid, predicted available time and the like; of course, the present embodiment may also adopt a combination of the above-mentioned multiple forms to display the current battery power of the system, which is not described herein again.
In step S110, how to detect the current battery level of the system is generally monitored and controlled by the power management chip, which calculates the battery level by detecting the battery voltage during the battery discharging process. For example, the voltage of a lithium battery of a general mobile phone at full charge is about 4.2V, and the discharge cut-off voltage is about 2.7V, so that the theoretical residual capacity of the battery can be converted by knowing the current battery voltage when the mobile phone is used.
For mobile terminals such as smart phones and tablet computers, the mainstream operating systems thereof are Android (Android), ios or Windows, and at present, Android is often installed. For the device installed with the android system, there is a battery management function, which sends a sticky system broadcast, and the function return value intent includes various information such as the current battery power state and the charging state, so that the current battery power of the system can be detected by registering a monitoring module with a battery power monitoring application program interface of the system.
Specifically, the monitoring may be registered in the system service, and the Level and Scale of the current power may be obtained by monitoring the battery power change message sent by battterymanager, so as to calculate the percentage of the current power, where an example code is as follows:
int level＝battery.getIntExtra(BatteryManager.EXTRA_LEVEL,-1)；
int scale＝battery.getIntExtra(BatteryManager.EXTRA_SCALE,-1)；
float batteryPct＝level/(float)scale；
therefore, by registering the monitoring module with the system, the embodiment of the invention can conveniently detect the current electric quantity of the system. When the residual electric quantity of the battery is lower than a certain level, the user can be prompted to adopt a corresponding power saving measure, or the user is prompted to charge in time, so that inconvenience caused by the exhaustion of the electric quantity of the battery is avoided.
After detecting the current battery power of the system, in step S120, the available time of the battery power is further analyzed, and the available time of the user can be estimated according to the total battery power, the current power and the weight obtained from the current switch setting state. The battery power usable time specifically includes two contents: firstly, calculating the battery electricity quantity usable time in the lowest electricity consumption using state, and if the battery electricity quantity usable time in the lowest electricity consumption using state is less than the expected battery using time, sending a charging prompt signal; and secondly, estimating the available time of the battery power in the current using state, if the available time of the battery power in the current using state is less than the expected battery using time, sending a low-power-saving prompt signal so as to switch the system to the corresponding low-power-saving using state according to the low-power-saving prompt signal, then judging whether the available time of the battery power in the lowest power consumption using state is less than the expected battery using time, and if so, sending a charging prompt signal. Therefore, when the electric quantity is low, the problem that the electric quantity of the battery is completely consumed before charging can be avoided by entering a low-electric-quantity electricity-saving use state in advance.
After the battery charge usable time is obtained, it can be determined whether the battery charge usable time is less than the expected battery use time according to step S130. The battery service life is generally a time length value of a work time period preset by a user, such as work time, business trip time, travel time and the like of a working day, and the expected battery service life is simply obtained by setting the starting point and the ending point of the time periods. When the battery capacity usable time is less than the expected battery use time, it indicates that the battery should be charged and saved in time, and in extreme cases, the battery should be shut down and replaced, otherwise the battery will be exhausted in the time period, thereby causing inconvenience to users.
When the above-mentioned judgment result indicates that the battery power available time is less than the expected battery available time, step S140 correspondingly sends a power maintenance prompt message. In this embodiment, the power maintenance prompt information may be a charging prompt signal, so as to prompt the user to charge in time, thereby avoiding the situation that the mobile phone and other devices cannot be normally used due to the exhaustion of the battery in a preset time period. The charging prompting signal can be in various forms such as sound, light or vibration signals, and the like, and the user can be conveniently prompted to take measures such as charging and the like in time through the easily-perceived signal. In this embodiment, the power maintenance prompt message may also be a low power saving prompt signal, which enables the user to switch the system to a corresponding low power saving state according to the low power saving prompt signal, thereby saving power of the portable electronic product.
The embodiment shown in fig. 1 has the functions of charging and saving electricity in an important time period, and triggers a charging or electricity-saving prompt signal by judging whether the usable time of the battery electricity quantity is less than the preset battery use time, so that the problem that whether the user cares about whether to keep enough electricity quantity to normally use equipment during the important time period of going to and going to work or not limited to the time of going to and going to work is solved, the product performance is improved, and the user requirements are better met.
As described above, in step S110, a monitoring module may be registered with a battery level monitoring application program interface of the system to detect the current battery level of the system. Under the condition, the system starts a background service to monitor the electric quantity change message of the system and filter the message, and when the electric quantity is judged to be low, a charging prompt signal or a low-electric-quantity power-saving prompt signal is triggered, so that a user is reminded of charging or saving power in time. As described further below in conjunction with fig. 2.
Referring to fig. 2, a process diagram for detecting the current power of the system in fig. 1 according to an embodiment of the present invention is shown. In fig. 2, after registering the monitoring module with the battery power monitoring application program interface of the system, the specific process of detecting the current battery power of the system includes: firstly, receiving a power change message provided by a system battery power monitoring application program interface (in step S210); then, filtering the power variation message (in step S220); and finally, summarizing the filtered electric quantity change messages and calculating the current battery electric quantity of the system (in step S230), wherein the obtained current battery electric quantity of the system is specifically displayed in the forms of percentage, filling grid and/or predicted available time and the like, and the intuitiveness is better.
As can be seen from the foregoing description, the present embodiment of the invention is premised on detecting the current battery level of the system; it can be understood that: the higher the detection frequency is, the more accurate the result is; however, the higher the detection frequency, the heavier the system is burdened and the power consumption of the system is increased. Therefore, the embodiment of the present invention adopts the technical solution of frequency conversion detection, which is further described as follows.
Referring to fig. 3, a process diagram for adjusting the detection frequency of the current power of the detection system in fig. 1 according to an embodiment of the invention is shown. The basic idea is to increase the detection frequency of the current battery capacity of the system when the current battery capacity of the system reaches a low battery capacity detection value, specifically: at the beginning, the detection frequency of the current battery power of the system is set to be a lower frequency (step S310); then, detecting the current battery level of the system according to the lower frequency (step S320); then, determining whether the current battery power of the system reaches a preset low power detection value (in step S330), where the low power detection value is higher than the low power threshold by a certain ratio, for example, 30% -40% of the full battery power; when the current battery capacity of the system is lower than the low battery capacity detection value, the detection frequency of the current battery capacity of the system is set to be a higher frequency (for example, 2 to 3 times of the initial value), and then the system continues to detect the battery capacity of the system according to the higher frequency.
In fig. 3, only the power variation around the battery "low battery state" is concerned, so that the burden of the system for continuously detecting the battery power is reduced, and the power consumption of the system is further reduced, which is undoubtedly beneficial to further saving power.
In the above embodiments, after the system enters the power saving mode desired by the user, the update frequency of all the started applications should be generally reduced, which is beneficial to further reducing the power consumption of the system, thereby achieving the purpose of better power saving.
As described above, the battery charge usable time includes the battery charge usable time in the lowest charge consumption use state and the battery charge usable time in the current use state. When the available time of the battery power in the current use state is less than the expected battery use time, but the available time of the battery power in the lowest power consumption use state is greater than the expected battery use time, the charging prompt signal can not be sent for the moment, and at the moment, the system can enter a low-power electricity-saving use state; and sending a charging prompt signal until the battery power available time in the lowest power consumption using state is also less than the expected battery use time, thereby reminding the user of charging. As described in further detail below.
Referring to fig. 4, a flowchart of a battery level guarantee method according to another embodiment of the invention is shown. This embodiment includes that the power saving reminds the function and charges and reminds the function: the system can be prompted to enter a low-power using state according to the available time of the battery power in the current using state, so that the purpose of saving power can be well achieved, the service time of the battery can be prolonged, and the main requirements of a user can be well met; the latter prompts the user to charge in time when the usable time of the battery power is less than the expected battery power in the lowest power consumption use state, thereby enabling the battery to keep enough power. The specific implementation process comprises the following steps:
in step S410, the current battery level of the system is detected, and the specific detection method can refer to the description of the embodiment shown in fig. 1.
Step S420, analyzing the available time of the battery power, specifically including calculating the available time of the battery power in the lowest power consumption usage state, and estimating the available time of the battery power in the current usage state, wherein: the battery power in the lowest power consumption use state is mainly used for charging prompt; the available time of the battery power in the current use state is mainly used for power saving prompt, so that the battery can be used for a longer time before charging.
Step S430, judging whether the available time of the battery electric quantity in the current using state is less than the expected battery using time, if so, entering step S440; if not, returning to step S410, continuing to detect the current battery level of the system. The determination condition in step S430 is equivalent to setting a low battery threshold, which is typically 15% to 25% of the full battery capacity, and the system can be triggered to enter the low battery usage state according to the determination condition.
Step S440, sending a low-battery power-saving prompting signal, so as to prompt the system to enter a low-battery use state, thereby prolonging the service time of the battery.
Step S450, judging whether the battery electricity quantity usable time in the lowest electricity consumption using state is less than the expected battery using time, if so, entering step S460; if not, returning to step S410, continuing to detect the current battery level of the system.
Step S460, a charging prompt signal is sent to prompt the user to charge in time, so as to avoid the situation that the mobile phone and other devices cannot be used normally due to the exhaustion of the battery in the preset time period.
In the embodiment shown in fig. 4, before sending the charging prompt signal, the low-battery power-saving prompt signal is sent, so that the system is switched to the corresponding low-battery power-saving use state in advance, and thus, the use time of the battery can be prolonged, and the problem that the battery power is completely consumed before charging is avoided.
In this embodiment, the system can be switched to the low power consumption state by turning off some power consumption switches. In addition, the system can also be switched to the low power consumption state by turning on a power saving mode, which is associated with a set of operating parameters and/or switch states related to the power consumption of the system. Correspondingly, the power saving modes include an optimal power saving mode, an ultra-long standby mode and an extreme power saving mode, and the main operating parameters and the switch states in the three power saving modes are shown in table 1:
TABLE 1 System operating parameters and on-off states under three power saving modes
Figure BDA0000977171330000101
As can be seen from table 1, the three power saving modes have the following characteristics:
in the best power saving mode, the set of the running parameters and/or the switch state related to the power consumption of the system at least sets the telephone state as on, the short message state as on, the network state as default by the user, the GPS state as off, the screen brightness as lowest and the screen overtime as shortest. In the best power saving mode, the telephone and the short message are started, and the network state is defaulted by the user, so that the power saving mode becomes the most common power saving state as the power saving mode can meet the main requirements of the user. Therefore, if the user does not make a corresponding selection, the system will select the optimal power saving mode by default, i.e. the system presets a state capable of receiving and sending a call and a short message at the time of low power, but all other switch settings are optimal.
In the ultra-long standby mode, the set of operating parameters and/or on-off states related to the power consumption of the system at least sets the phone state as on, the short message state as on, the network state as off, the GPS state as off, the screen brightness as lowest, and the screen timeout as shortest. In this ultra-long standby mode, the network is turned off without affecting standby, and thus, the most basic call and sms functions can be provided to the user.
In the extreme power saving mode, the set of operating parameters and/or switch states related to the power consumption of the system at least sets the phone state as off, the short message state as off, the network state as off, the GPS state as off, the screen brightness as lowest, and the screen timeout as shortest. In the extreme power saving mode, the system can only be guaranteed to be running, but the system cannot make a call, send a short message and the like, so that a general user can only use the system at a specific time.
Therefore, in the embodiment, three power saving modes are preset in the system, and a user only needs to simply select one of the three power saving modes when switching the power saving use state of the battery without setting specific operation parameters or the switch state of the system, so that the operation is very simple and convenient, and the possibility of setting errors by self is avoided.
The battery capacity guaranteeing methods of the two embodiments of the present invention are described in detail above. On the basis, the invention also correspondingly constructs a battery power guarantee device (hereinafter referred to as device) which can better achieve the purpose of power saving, and the detailed description is given below.
Incidentally, if the charging process in the device of the present embodiment is not exhaustive, please refer to the description of the method section above; likewise, where the foregoing method section refers to equipment, reference may also be made to the following description of the equipment section.
Referring to fig. 5, a block diagram of a battery level assurance apparatus according to an embodiment of the present invention is shown. In the device 500 shown in this embodiment, the background service registers monitoring of the change of the battery power information, and after the battery power change is received and filtered, the approximate usable time of the device in the current state is estimated by combining the current device switch state and the usable time of the battery power in different device states, and if the time is less than the on-duty time period or other set time intervals set by the user, the following processing is performed: if the user can save power by closing the switches, prompting the user to switch the running mode or close some power consumption switches; and if the electric quantity of the user cannot be used for a desired time even under the condition of ensuring the mobile phone consumption of the user at the lowest level, prompting the user to charge. The apparatus 500 is described in further detail below in conjunction with fig. 5.
As shown in fig. 5, the apparatus 500 is composed of a battery power detector 510, a power available time resolver 520, a power maintenance controller 530, and a display 540, wherein: the battery power detector 510 is connected to the system battery power monitoring application program interface 600; the battery power detector 510, the power available time analyzer 520, and the power maintenance controller 530 are connected in sequence; the display 540 is connected to the battery power detector 510, the power available time analyzer 520, and the power maintenance controller 530, respectively. The functions of the various components of the device 500 are described in detail below.
The apparatus 500 has a battery level detector 510 coupled to the system battery level monitor api 600 for detecting the current battery level of the system in real time. The battery charge detector 510 is also connected to the display 540, so that the current battery charge data of the system obtained by the battery charge detector 510 is displayed on the display 540. In general, the current battery charge data of the system may be presented on the display 540 in the form of a percentage, a fill cell, and/or a predicted available time, which is intuitive.
The device 500 has a battery age parser 520 that can parse the battery age, including calculating the battery age in the lowest power consumption usage state and the battery age in the current usage state, which can be displayed on the display 540, wherein: the battery electricity quantity usable time in the lowest electricity consumption use state is used as a charging prompt; the available time of the battery power in the current use state is used as a power saving prompt.
The device 500 also has a power maintenance controller 530 that can send a power maintenance prompt when the battery power is available for a time less than a desired battery usage time, thereby prompting the user to charge and/or save power in a timely manner, thereby ensuring that the user's portable electronic product maintains sufficient power for an important period of time.
Specifically, the power maintaining controller 530 includes a charging control module 531, which sends a charging prompt signal when it is determined that the battery power available time in the lowest power consumption usage state is less than the expected battery usage time, where the charging prompt signal may be an acoustic, optical or vibration signal; or the text or picture information can be displayed on the display 540, and the function of opening the screen, namely popping up the prompt, can be realized.
In addition, the power maintenance controller 530 of the apparatus 500 shown in fig. 5 further has a power saving control module 532 for determining whether the battery power available time in the current usage state estimated by the power available time analyzer 520 is less than the expected battery usage time. If the available time of the battery power in the current use state is less than the expected battery use time, a low power saving prompt signal is correspondingly sent so that the system is switched to the corresponding low power saving use state by the low power saving prompt signal, the power consumption of the battery is reduced, and the aim of saving the battery power is fulfilled.
Specifically, the power saving control module 532 may switch on a power saving mode (e.g., switching the system to a low power saving mode, wherein the power saving mode is associated with a set of operating parameters and/or switch states related to the power consumption of the system, and the power saving mode is implemented by modifying the operating parameters and/or switch states, where the power saving control module 532 may be connected to the display 540, so as to display a power saving mode setting interface on the display 540, so that the user may conveniently select the preset power saving mode, and finally complete setting of the power saving mode desired by the user.
Incidentally, the charging control module 531 and the power saving control module 532 may not be integrated in the power maintaining controller 530, that is, they are independent components and respectively undertake the corresponding charging prompting or power saving prompting functions, and the specific functions and control manners can refer to the above description.
As shown in fig. 5, the battery level detector 510 is an important component of the apparatus 500, and has a monitoring module 511, which detects the current battery level of the system by registering with the system battery level monitoring application program interface 600. The basic process of the battery power detector 510 detecting the current battery power of the system is to receive the power change message provided by the system battery power monitoring application program interface, then filter the power change message, then summarize the filtered power change message and calculate the current battery power of the system, thereby efficiently and accurately obtaining the battery power of the system. In particular, the battery power detector 510 can increase the detection frequency of the current battery power of the system when the current battery power of the system reaches a certain low power detection value, i.e. the detection frequency near the low power is greater than the initial detection frequency, thereby reducing the system load and further reducing the system power consumption.
The device 500 of the above embodiment may further reduce the update frequency of all the started applications after the system enters the power saving mode desired by the user, so as to further reduce the power consumption of the system, which is very beneficial to prolonging the continuous service time of the device.
The device 500 in the above embodiment has an active charging reminding function for going to work or other preset time periods, and also has a power saving reminding function, and the implementation process is simple and convenient:
1. setting the time points of going to and going from work, and other time periods can be set;
2. the background service registers monitoring on the change of the battery power information, the battery power change is received and filtered, the approximate usable time of the equipment in the current state is estimated by combining the current equipment on-off state, and if the time is less than the on-off time period set by a user, the battery power usable time in different equipment states is calculated:
a. if the user can realize power saving by closing the power consumption switches, prompting the user to switch the running mode or close some power consumption switches;
b. if the charge of the battery cannot be used for a desired period of time even if the minimum consumption of the user equipment is ensured, the user is prompted to charge.
Therefore, the device 500 of the above embodiment has the function of actively reminding charging in an important time period, and triggers the charging prompt signal by judging whether the battery capacity usable time is less than the preset battery use time, so that the problem that whether enough battery capacity can be normally used in an important time period, which is concerned by a user and is about to go to work or not, or is not limited to the time of going to work or not is solved, the product performance is improved, and the user requirements are better met.
In addition, the device 500 has a function of actively reminding power saving in an important time period, and specifically, the system can be prompted to enter a low power consumption state according to the available time of the battery power in the current use state, so that the purpose of power saving can be well achieved, the service time of the battery is prolonged, and the main requirements of a user can be met.
The battery power guarantee device can be particularly applied to various mobile terminals, particularly portable electronic devices such as smart phones, smart tablet computers, smart game machines, smart navigators, smart remote controllers and smart set-top boxes, wherein the host is provided with an android operating system. The main machines of the mobile terminals are powered by batteries, and after the electric quantity guarantee equipment is installed, users can be guaranteed to keep enough electric quantity required by normal use of the equipment in important time periods such as work hours and work hours, so that the product performance is improved, the requirements of the users are well met, and the market prospect is good.
