Description

Mobile communication terminal and power control method thereof

The invention relates to a handheld electronic device and a power control method thereof, in particular to a mobile communication terminal and a power control method thereof.

In recent years, due to the development of network and communication technologies, various mobile communication products have become smaller and smaller in size, more and more complete in functions, and easy to carry, and thus have been loved by people. In particular, at present, the most common mobile phones, in addition to solving the general wireless communication needs, such as telephone, short message, GPRS Internet access and other communication functions, also added scheduling, calculation, games, photos and other value-added functions, these value-added functions This eliminates the need to carry separate devices with corresponding functions, such as clocks, calculators, cameras, etc.

However, although the existing mobile phone adds a lot of value-added functions, these value-added functions are provided simultaneously with the communication function, that is, since the user starts up, both the value-added function module and the communication function module are activated. In this way, it is bound to consume a certain amount of unnecessary power, resulting in a shortened standby time of the mobile phone and a reduced battery life of the mobile phone. In addition, the current mobile phone has a power detection function, and displays a battery bar on the display screen to remind the user to charge in time. However, the battery bar can only vaguely indicate the current power of the mobile phone. It is not possible to predict exactly when the mobile phone will be used. For example, in the case of low power, the user has an important call at a certain moment, but because the mobile phone consumes some unnecessary power during use, the power consumption is accelerated, and the user cannot Predicting the usage time of the mobile phone, the user is worried that the communication will be interrupted at any time when using the mobile phone. Therefore, the user only wants to use his telephone function module, and wants to turn off other function modules, so that the battery life of the mobile phone can be extended to the time required by the user.

In view of this, it is necessary to provide a mobile communication terminal in which the function module is turned off according to the time required by the user.

In addition, it is also necessary to provide a method of controlling the power of the mobile communication terminal that is turned off according to the time required by the user.

A mobile communication terminal includes a power source, a power detection module, a control module, a setting module, a power consumption calculation module, a comparison module, and a plurality of function modules. The power supply supplies power to each functional module. The power detection module is used to detect the remaining power of the power supply. The function module provides various functions for the mobile communication terminal, and each function module has a preset level. Set the module for the user to set the time. The power consumption calculation module calculates the reference power consumption according to the time and remaining power set by the user, and calculates the power consumption of the function module with the highest preset level and the current total power consumption of each function module. The comparison module compares the power consumption of the functional module with a higher preset level with the reference power consumption. If the power consumption of the function module with the highest preset level is less than the reference power consumption, the comparison module compares the current total power consumption of each function module with the reference power consumption. If the current total power consumption of each function module is greater than the reference power consumption, the control module closes according to the preset level of each function module from low to high. The function module until the total power consumption of the remaining function modules is less than or equal to the reference power consumption.

A power control method for a mobile communication terminal, comprising: receiving a time set by a user; detecting a remaining power of the power source; calculating a reference power consumption according to a current power supply of the current power source and a time set by the user; and calculating a function module with the highest preset level Power consumption; determine whether the power consumption of the function module with the highest preset level is less than the reference power consumption; if the power consumption of the function module with the highest preset level is less than the reference power consumption, calculate the current total power consumption of each function module; Whether the current total power consumption of each function module is greater than the reference power consumption; if the current total power consumption of each function module is greater than the reference power consumption, the corresponding function is turned off according to the preset level of each function module from low to high. The module until the remaining functional modules are less than or equal to the reference power consumption.

By adopting the above-mentioned mobile communication terminal and the power control method of the mobile communication terminal, the time can be set according to the needs of the user, and the shutdown of each functional module can be controlled according to the time set by the user, thereby reducing the power consumption of the mobile communication terminal, thereby extending the mobile communication terminal.

The power detecting module 20 is configured to detect the remaining power of the power source 10.

The battery bar 30 is used to display the remaining state of the power source 10.

In this implementation, each function module corresponds to a preset level, that is, there are N preset levels, and in other embodiments, multiple function modules may correspond to one preset level, that is, there are M preset levels. Where M is a natural number and M < N.

According to the remaining state of charge displayed by the battery bar 30, the user can roughly know the remaining battery power of the current power source 10. If the user is worried that the usage time of the mobile communication terminal 200 cannot reach the time required by the user, the user can set the time required by the user through the setting module 40. At this time, the setting module 40 generates a time signal.

After receiving the time signal, the power consumption calculation module 60 calculates the reference power consumption according to the time set by the user and the remaining power of the current power source 10, and the reference power consumption indicates that the mobile communication terminal 200 wants to reach the time set by the user, where The amount of electricity consumed per unit of time. The power consumption calculation module 60 also calculates the power consumption of the function module 80n having the highest preset level, and the current total power consumption of the function modules 801, 802.....80n.

The comparing unit 70 first compares the power consumption of the function module 80n with the highest preset level with the reference power consumption. If the power consumption of the function module 80n with the highest preset level is less than the reference power consumption, the comparing unit 70 continues to function. The current total power consumption of groups 801, 802...80(n-1), 80n is compared with the reference power consumption; if the total power consumption of the functional modules 801, 802...80(n-1), 80n is greater than the reference The power consumption, comparison unit 70 sends a trigger signal to the control module 50.

After receiving the trigger signal, the control module 50 turns off the corresponding function module according to the preset level of each function module from low to high, until the total power consumption of the remaining function modules is less than or equal to the reference power consumption. . Specifically, the control module 50 turns off the function module 801 with the lowest preset level; the power consumption calculation module 60 calculates the total power consumption of the remaining function modules 802...80(n-1), 80n; Group 70 compares the total power consumption of the remaining functional modules 802...80(n-1), 80n with the reference power consumption; if the remaining functional modules 802...80(n-1), The total power consumption of 80n is less than or equal to the reference power consumption, and the remaining functional modules 802...80(n-1), 80n are all working normally; if the remaining functional modules 80 ₂ ... 80 _{(n- 1)} The total power consumption of 80 _n is greater than the reference power consumption, and the control module 50 continues to turn off the remaining functional modules 80 ₂ ... 80 _(n-1) , the lowest level functional module 802 of 80 _n , In turn, until the total power consumption of the remaining functional modules is equal to or less than the reference power consumption.

In the above embodiment, the control module 50 closes the corresponding function module in a step-by-step manner. In other embodiments, the control module 50 can be closed at the same time. Specifically, the control module 50 selects the function module 801 with the lowest preset level; the power consumption calculation module 60 calculates the current total of the unselected function modules 80 ₂ ... 80 _(n-1) , 80 _n Power consumption; the comparison module 70 compares the current total power consumption of the unselected function modules 80 ₂ ... 80 _(n-1) , 80 _n with the reference power consumption; if the function module is not selected 80 ₂ ... 80 _(n-1) , 80 _n current total power consumption is less than or equal to the reference power consumption, the control module 50 turns off the selected function module 801; if not selected function module 80 ₂ ...80 _(n-1) , 80 _{n The} current total power consumption is greater than the reference power consumption, and the control module 50 continues to function in the unselected power-consuming functional modules 80 ₂ ... 80 _{(n-1) In the} 80 _n , the function module 80 ₂ with the lowest preset level is selected, and the selected power module is turned off until the total power consumption of the unselected function module is less than or equal to the reference power consumption.

In the process of using the mobile communication terminal 200, if one or more function modules are used within the user set time, the function modules are stopped and used to enter the standby state, and a detection signal is generated to trigger the power detection module. 20 Re-detecting the remaining power of the power source 10, the power consumption computing module 60 recalculates the reference power consumption. In this way, after the power consumption of the functional modules is consumed, the mobile communication terminal 200 still uses the original reference power consumption as a condition for turning off the function module.

In addition, when the mobile communication terminal 200 is used, if the user has not set the time, the various functional modules of the mobile communication terminal 200 operate normally until the mobile communication terminal 200 is turned off.

In addition, when the mobile communication terminal 200 is used, if the user sets the time, but the total power consumption of the function module 80 _n with the highest preset level is equal to the reference power consumption, the control module 50 directly turns off all the non-highest preset levels. Function modules 80 ₁ , 80 ₂ , ... 80 _(n-1) ; if the user sets the time, but the power consumption of the function module 80n with the highest preset level is greater than the reference power consumption, that is, only the pre-preservation is retained. In the case of the highest level function module 80 _n , the time set by the user cannot be reached.

In step 422, the control module 50 turns off the function modules with the lowest preset level among the function modules 80 ₁ , 80 ₂ ... 80 _(n-1) and 80 _n .

In step 424, the power consumption calculation module 60 calculates the total power consumption of the remaining function modules.

Step 426, the comparison module 70 determines whether the total power consumption of the remaining function modules is greater than the reference power consumption. If the total power consumption of the remaining function modules is greater than the reference power consumption, then step 428 is entered; if the remaining functional modules are If the total power consumption is less than or equal to the reference power consumption, then step 430 is entered.

In step 428, the control module 50 closes the function module with the lowest preset level among the remaining function modules, and performs step 424.

Step 430, if a function module is used within the time set by the user, the function module stops using and enters the standby state, and then sends a detection signal to the power detecting module 20, and the power detecting module 20 receives the detecting. The signal is executed in step 404. If no function module is used, the power detecting module 20 does not receive the detection signal, and step 430 is performed.
