detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

FIG. 1 is a schematic flowchart diagram of a charging current limiting method according to an embodiment of the present invention. As shown in FIG. 1, the charging current limiting method includes:

Step 0100: Obtain current motion state information and current usage state information of the mobile terminal.

The current motion state information is used to indicate the amount of motion state of the mobile terminal in the corresponding time to evaluate the motion state of the mobile terminal. The motion state information may be an acceleration state, wherein the acceleration state includes an acceleration change state and an acceleration non-change state. The acceleration state may be obtained by the following parameter information: the parameter information includes velocity information of the mobile terminal in a uniform motion state, static state information, velocity information in a variable motion state, angular velocity information, angular acceleration information, and a formula derived from the above physical quantities. Forming some information for evaluating the motion state of the mobile terminal. Like moving The displacement information of the terminal and the centripetal force information of the mobile terminal for circular motion are all derived from the above physical quantities by formula derivation to form a certain parameter information for evaluating the motion state of the mobile terminal. Therefore, those skilled in the art should understand that when establishing a correspondence relationship between mobile terminal motion state information and other elements, the motion state information can be appropriately equivalently replaced, regardless of which parameter is used as an evaluation element of the motion state information. The conception and transformation of the embodiments should be within the scope of the invention.

When the mobile terminal performs charging, the user can use the mobile terminal to complete the service, and the motion state information can be used as one of the criteria for judging the mutual contact between the user and the external surface of the mobile terminal. In some application scenarios, during the process in which the user completes the service using the mobile terminal, the acceleration of the mobile terminal may change. Therefore, whether the mobile terminal is in the motion state and the specific state of the motion may be determined according to the acceleration state. Further, the acceleration state can also determine whether the outer surface of the user and the mobile terminal are in contact.

In some embodiments, multiple ways can be taken to obtain the acceleration state of the mobile terminal. For example, the acceleration sensor may be set in the mobile terminal to collect the acceleration of the corresponding moment of the mobile terminal; the gyro or the three-axis sensor may be set in the mobile terminal to collect the angular acceleration of the corresponding moment of the mobile terminal. The acquisition here may be that the processor collects the output data of the acceleration sensor or the gyroscope or the three-axis sensor at intervals.

FIG. 1 is a schematic flowchart of obtaining an acceleration state of a mobile terminal according to an embodiment of the present invention. As shown in Figure 1a, the process includes:

Step 01001: Acquire a current acceleration value and a previous acceleration value;

The last acceleration information is referenced to the current acceleration information, and is closest to the acceleration information of the current acceleration information. For example, the current acceleration information is the acceleration information output by the processor at the tenth time, and the last acceleration information is the acceleration information output by the processor at the ninth time. The acceleration information of the acceleration sensor can be collected by the processor in a software manner or a hardware manner or a combination of software and hardware.

In this embodiment, when the acceleration information output by the acceleration sensor is collected by software, when the processor collects the acceleration information of the current acceleration sensor, and then performs the operation of acquiring the acceleration sensor again, it needs to delay for a certain time, and then proceed. The next acquisition operation.

Step 01002, subtracting the current acceleration value from the previous acceleration value, and taking the absolute value of the error of the phase subtraction result;

Step 01003, determining whether the absolute value of the error is greater than a preset acceleration threshold;

Since the acceleration sensor is sensitive to changes in speed, in order to prevent false positives and improve reliability Sex, preset acceleration threshold information is necessary. The preset acceleration threshold information is determined by the model of the acceleration sensor and the purpose of the operation.

Step 01004, if the absolute value of the error is greater than the preset acceleration threshold, the current acceleration state is an acceleration change state;

Step 01005: If the absolute value of the error is less than the preset acceleration threshold, the current acceleration state is an acceleration non-change state.

The process is used to obtain the acceleration state of the mobile terminal, which can accurately determine the current acceleration state of the mobile terminal, thereby laying a foundation for more accurately adjusting the charging current.

The current usage status information is the current usage status of the mobile terminal. For example, the current user holds the mobile terminal and puts the mobile terminal in a lock screen state to play music. For example, the current user places the mobile terminal with a backpack and puts the mobile terminal in a lock screen state to play music. For example, the current user places the mobile terminal on a desk for charging. For example, the current user holds the mobile terminal to answer the call. For example, the current user views the video through the mobile terminal.

The usage status information is used to characterize the state in which the mobile terminal is used, for example, when the mobile terminal is charging, the user uses the mobile terminal to watch a video or make a phone call, or the handheld mobile terminal listens to music, or downloads, or edits text, or moves The terminal is placed on a desk for charging, or playing a game, or reading, or using an application software in a mobile terminal, and the like. In the above mobile terminal application scenario, when watching a video or making a call, the screen of the mobile terminal is lit at this time, and therefore, the usage status information here is a screen lighting state. Of course, it is also possible to extract the evaluation element between the viewing video and the telephone call that can be used to evaluate the viewing video and the telephone call, and use the evaluation element as the usage status information. For example, when watching a video or making a call, the speed at which the processor processes data or memory calls is different, so in some embodiments, the speed at which the processor processes data or memory calls can be used as an evaluation factor.

In some application scenarios, when the handheld mobile terminal listens to music, the screen of the mobile terminal is turned off at this time, and therefore, the usage status information here is the screen off state. When editing text, the usage status information here is the screen lighting status. When downloading, the usage status information here is that the screen is off. The mobile terminal is placed on a desk for charging, and the usage status information here is that the screen is off. When playing a game or using an application software in a mobile terminal, the usage status information here is a screen lighting state.

In some application scenarios, when the handheld mobile terminal talks for a long time, the temperature of the surface of the mobile terminal and the area contacted by the hand increases. Therefore, the usage status information herein is the temperature of the surface of the mobile terminal.

In this implementation, the current usage status letter of the mobile terminal is obtained according to different usage status information. The way of interest is different. For example, the current usage status information is the screen lighting state or the screen is off state, the processor accesses the screen lighting circuit control module through software mode, and knows that the screen lighting state or the screen is off state; or accesses the screen lighting circuit control module through hardware mode. Knowing the screen lighting information or the screen extinguishing information; or accessing the screen lighting circuit control module through cooperation of software and hardware, and knowing the screen lighting information or the screen extinguishing information. Those skilled in the art can implement the functions of the screen lighting circuit control module in this embodiment according to the content of the present invention and the prior art. For example, the current usage status information is the size information of the memory call, and the processor accesses the memory by using software and/or hardware, and knows the memory call size relationship. When the user views the video, the current usage status information is a large memory call information. When the user edits the short message, the current usage status information is a small memory call information.

Step 0102: Adjust the charging current of the mobile terminal according to the current motion state information and the current usage state information.

The mobile terminal establishes a charging current adjustment table based on the motion state information and the usage state information. When the mobile terminal acquires the current motion state information and the current usage state information, the charging current adjustment table is searched for, and the corresponding charging current adjustment relationship is matched to adjust the charging current of the mobile terminal. Table 1 is a schematic diagram of a charging current adjustment table according to an embodiment of the present invention.

Table 1

As shown in Table 1, the charging current adjustment relationship is a preset correspondence relationship between the motion state information of the mobile terminal, the usage state information, and the charging current. The charging current adjustment relationship includes at least three charging current relationships, which are a first charging current relationship, a second charging current relationship, and a third charging current relationship, respectively. The first charging current in the first charging current relationship is smaller than the second charging current in the second charging current relationship, and the charging current in the second charging current relationship is smaller than the charging current in the third charging current relationship. The first charging current, the second charging current, and the third charging current herein are divided according to the type of the mobile terminal, the type of charging used, and the purpose of the job. Further, in some embodiments, the plurality of grading current charging relationships may be further divided in the first charging current relationship, so that the corresponding current can be accurately provided according to the motion state information and the usage state information of the mobile terminal. It can improve the charging efficiency, on the other hand, it can enhance the user's experience. Similarly, the second charging current relationship or the third charging current relationship can continue to divide the plurality of levels of current charging relationships.

The current motion state information includes a current acceleration change state and a current acceleration no change state, and the current use state information includes a current screen lighting state, a current screen extinguishing state, and a current temperature state. The processor can find a charging current suitable for the current mobile terminal according to the current motion state information and the current usage state information, combined with the charging current adjustment relationship.

If the current acceleration state is the current acceleration change state, and the current screen state is the current screen lighting state, the charging current of the mobile terminal is adjusted to the first charging current. In some application scenarios, the user holds the mobile terminal to watch the video or make a call, or the handheld mobile terminal listens to music, or downloads, or edits the text. At this time, the current acceleration state of the mobile terminal is the current acceleration change state, and the current screen state is the current screen. In the lighting state, the heat generated by the mobile terminal is relatively high, so it is necessary to reduce the charging current. At this time, the processor sends a control command to the charging control module, and the charging control module limits the charging current at this time to the first charging current according to the control instruction, so as to limit the heat when the mobile terminal is charged, on the one hand, avoiding the user long The mobile terminal with relatively high temperature contact time can on the other hand reduce the heat generation of each hardware inside the mobile terminal, and avoid the problem that the operating speed of the mobile terminal decreases due to excessive hardware temperature.

If the current acceleration state is the current acceleration change state, and the current screen state is the current screen off state, the charging current of the mobile terminal is adjusted to a second charging current, wherein the first charging current is less than the second charging current. In some application scenarios, the user holds the mobile terminal or puts the mobile terminal into the backpack, places the mobile terminal in a lock screen state, and plays music. At this time, the current acceleration state of the mobile terminal is the current acceleration change state, and the current screen state is the current screen off state, and the current screen state is The amount of heat generated by the mobile terminal is reduced relative to the amount of heat generated by the scene corresponding to the first charging current. At this time, in order to balance the charging efficiency and the heat amount of the mobile terminal, the processor limits the current of the mobile terminal at this time through the charging control module. At the second charging current. On the one hand, it is possible to improve the charging efficiency with respect to the scene corresponding to the first charging current, and on the other hand, it can reduce the amount of heat generated by the mobile terminal.

If the current acceleration state is the current acceleration no change state, and the current screen state is the current screen off state, the charging current of the mobile terminal is adjusted to a third charging current, wherein the second charging current is less than the third charging current. In some application scenarios, the user places the mobile terminal on a desk or the like for charging, and the user does not touch the mobile terminal at this time. The current user's urgent need for mobile terminals is to shorten the charging time of mobile terminals. At this time, the current acceleration state of the mobile terminal is the current acceleration no change state, the current screen state is the current screen off state, and the heat quantity of the mobile terminal is reduced relative to the heat generated by the scene corresponding to the second charging current. In this case, in order to shorten the charging time, To improve the charging efficiency, the processor limits the current of the mobile terminal to the third charging current through the charging control module.

If the current acceleration state is the current acceleration change state, and the temperature information indicates that the temperature of the current mobile terminal is higher than the threshold, the charging current of the mobile terminal is adjusted to the safe current. The temperature sensor built in the mobile terminal can collect the surface temperature touched by the current user's handheld mobile terminal. The temperature sensor transmits the collected data to the processor, and the processor processes and analyzes the collected data. When the user holds the mobile terminal for a long time to answer the call, the temperature of the surface of the mobile terminal will increase. At this time, if the charging is continued, the mobile terminal generates a large amount of heat. Due to the temperature rise of each hardware inside the mobile terminal, the operation efficiency is low, and the user holds the high temperature mobile terminal, and the experience is poor. Therefore, the temperature of the surface of the current mobile terminal is greater than the temperature threshold, and the charging of the mobile terminal is stopped, thereby greatly reducing the heat caused by the charging.

It should be noted that the various application scenarios described above are merely exemplary scenarios presented in this embodiment, and should not be considered as limiting the scenarios to be implemented in the future of the present invention.

In some embodiments, when the charging control module of the mobile terminal is a wired charging control module, the wired charging control module includes a charging chip and other charging peripheral circuits, and the content of the training according to the embodiment of the present invention is combined with the existing The invention can achieve the object of the invention. The external power supply supplies power to the mobile terminal through a charging line. For example, the mobile terminal is connected to 220V AC through an adapter, and the processor of the mobile terminal automatically adjusts the charging current according to the result of the final selection of the charging current relationship.

In some embodiments, when the charging control module of the mobile terminal is a wireless charging control module, the wireless charging control module includes a wireless transceiver circuit module and a wireless control circuit module. When charging wirelessly, The receiving coil of the wireless transceiver circuit module receives the wireless signal sent by the transmitting coil of the transmitting end, and outputs a current signal, and the wireless control circuit module automatically adjusts the charging current according to the control command sent by the processor.

The external power supply devices herein may be mobile portable charging devices, batteries, power supplies for external grid inputs, and the like.

The mobile terminal can be, for example, a Personal Digital Assistant PDA, a tablet, a smart phone, a smart bracelet, a smart watch, a smart wearable device, an electronic paper book, a cellular phone, a tablet computer, a media player, a laptop computer, etc. Portable mobile electronic devices.

In this embodiment, the current state information of the mobile terminal and the current state of use information are acquired, and the charging current of the mobile terminal is adjusted according to the current motion state information and the current state of use information. Therefore, it is possible to flexibly adjust the charging current according to the scene used by the mobile terminal, thereby relatively improving the charging efficiency.

2 is a schematic flow chart of another charging current limiting method according to an embodiment of the present invention. As shown in FIG. 2, the charging current limiting method includes:

Step 0200: Obtain current motion state information and current usage state information of the mobile terminal.

Step 0202: Obtain an application type of an application currently running by the mobile terminal;

Step 0204: Determine whether the application type matches the preset application type.

Step 0206: If the application type matches the preset application type, when the current acceleration state information indicates that the current mobile terminal is in an acceleration change state, and the current screen state information indicates that the current mobile terminal is in the screen lighting state, the charging current of the current mobile terminal is adjusted. To safe current;

Step 0208: If the application type does not match the preset application type, the original charging state is maintained.

The mobile terminal supports the running of various applications, which may be a game application, a call application, a drawing application, a presentation application, a word processing application, a spreadsheet application, a game application, a phone application. , video conferencing applications, email applications, instant messaging applications, training support applications, photo management applications, digital camera applications, and more.

The mobile terminal extracts the type identifier of the application from the thread pool, and matches the corresponding application type according to the extracted type identifier. However, different applications are in the same state of operation, and the amount of power consumed is different. In order to better improve the charging efficiency and reduce the probability of accidents caused by the user using a specific application in a charging state, the present embodiment presets a specific application type according to the power consumption characteristics of the application type. When the application type of the currently running application matches the preset application type, the current acceleration status information indicates that the current mobile terminal is in an acceleration change state, and when The front screen status information indicates that the current mobile terminal's charging current is adjusted to a safe current when the current mobile terminal is in the screen lighting state. Here, the preset reference type includes a game application and/or a call application. The designer can determine the safety current warning value according to the purpose of the operation.

The charging process of the mobile terminal includes a trickle charging phase, a constant current charging phase, and a constant voltage charging phase. According to the normal charging process, the battery that has passed through three charging phases is more capable of exhibiting performance than the battery directly switched to a specific current value. Superior. However, in order to reduce the probability of accidents caused by the user using a specific application in a state of charge, and to limit the charging current to a safe current, if the charging mode is adopted for the mobile terminal for a long time, there is a decrease in battery life and battery life. The danger of ability. Therefore, in order to avoid such a problem, optionally, as shown in FIG. 3, in some embodiments, the charging current limiting method further includes:

In step 0210, when it is detected that the running time of the application currently running by the mobile terminal is greater than the preset duration, the charging of the mobile terminal is stopped.

The mobile terminal accesses the thread pool and obtains the running time of the currently running application from the thread pool. When the running time is longer than the preset duration, the charging of the mobile terminal is stopped. Therefore, it is possible to stop charging the mobile terminal in the use scenario, thereby improving battery life and battery life.
