  In order to determine the current consumption of an electronic device using conventional technology, the usage model is determined after investigating how the electronic device is used, and the electronic device is operated according to the determined usage model There was a problem that it took a long time to measure the current consumption. On the other hand, by understanding how much current is consumed for each operation performed by the electronic device in each usage model, the current consumption is based on the execution time of each operation content in each usage model. It is conceivable to calculate the estimated value of current consumption without actually measuring.

  However, in an electronic device, various types of application programs are executed, and various processes with different current consumption are executed while the application programs are being executed. Conventionally, it was difficult to determine what kind of processing with different current consumption is being performed in the electronic device, so it is difficult to determine the operation content in the usage model of the electronic device and the execution time of each operation content. there were. As a result, since the operation content and execution time are determined by human sense, the actual internal operation status of the electronic device is not reflected in the usage model, and the accuracy of the estimated current consumption is low. there were.

  The classification unit identifies a first change timing at which the operation content of the electronic device has changed based on a timing at which the average value of the current consumption calculated every predetermined time has changed, and the output unit includes the output unit The first change timing specified by the classification unit may be output.

  The output unit may output the average value in association with the elapsed time. The output unit may output information indicating a current range in which the consumption current is classified among the plurality of current ranges in association with the elapsed time.

  The classification unit identifies a second change timing at which the operation content has changed based on a combination of the plurality of components identified as being operated by the operation state identification unit, and the output unit includes the classification The second change timing specified by the unit may be output. In this case, the output unit outputs information indicating a combination of the plurality of constituent elements identified as being operated by the operation state specifying unit in association with the elapsed time.

  The calculation unit subtracts a current value consumed by the operation state specifying unit or the calculation unit from a consumption current calculated based on the operation state specified by the operation state specifying unit and the element-specific consumption current. Thus, the current consumption of the entire electronic device may be calculated.

[Outline of operation of portable terminal 1]
FIG. 1 is a diagram for explaining an outline of the operation of the mobile terminal 1 that is the electronic apparatus of the present embodiment. The mobile terminal 1 is an electronic device that can transmit and receive data to and from other communication terminals via a base station of a mobile terminal network. The mobile terminal 1 is a program used for determining a usage model that is an average usage mode used by the user of the mobile terminal 1 and is used by the current consumption calculation program (hereinafter referred to as an operation content determination program). Is installed. The portable terminal 1 is installed with a program for calculating current consumption (hereinafter referred to as a current consumption calculation program).

  The consumption current calculation program is a program used by a quality control person such as a manufacturer that provides the mobile terminal 1 or a communication carrier, for example. In this specification, a quality control person or the like who specifies the consumption current of the portable terminal 1 using the consumption current calculation program is called a terminal evaluator, and a person who purchases and uses the portable terminal 1 is called a user.

  The consumption current calculation program is a simulation application that causes various operation contents based on the usage model of the mobile terminal 1 to be executed by a plurality of components built in the mobile terminal 1 in a simulated manner. The terminal evaluator can evaluate the consumption current and the battery duration of each portable terminal 1 by causing various portable terminals 1 to execute a consumption current calculation program. Although details of the constituent elements will be described later, the constituent elements are, for example, a CPU (Central Processing Unit), a display, a communication unit, and the like. The operation content includes, for example, activation of an application program, display page transition during execution of the application program, screen scroll display, standby operation with low power consumption, and the like.

  The operation content determination program is a program that is executed before the terminal evaluator calculates the current consumption of the mobile terminal 1 using the current consumption calculation program. The mobile terminal 1 executes another application program (hereinafter referred to as a user application) used by a general user in a state where the operation content determination program is activated, and each component while the user application is being executed. Monitor the operating status of The mobile terminal 1 stores the current consumption value of the entire mobile terminal 1 in association with the elapsed time based on the operation state of each component and the known current consumption by element when each component operates. To remember.

  While the mobile terminal 1 executes the operation content determination program, the current consumption value is classified into a plurality of current ranges based on the change mode of the current consumption value stored in the memory, and the user application is being executed. The timing at which the content of the operation changes is specified. Specifically, the mobile terminal 1 specifies in which range the average current consumption within a predetermined time is included in a plurality of current value ranges, and in a period in which the average current consumption is included in different ranges. The operation that has been performed is different.

  The portable terminal 1 outputs the average current consumption of each operation content in association with the time during which each operation content was executed. The terminal evaluator can specify the type of operation content that occurs when the mobile terminal 1 executes the user application based on the output information. The terminal evaluator can calculate the current consumption when the user application is executed in various usage models by executing the current consumption calculation program based on the operation content thus specified.

  FIG. 2 is a diagram for explaining the contents of the operation executed by the mobile terminal 1 in the first usage model. The terminal evaluator can create the usage model shown in FIG. 2 based on the result output from the mobile terminal 1 that has executed the operation content determination program according to the present embodiment.

  FIG. 2 shows a usage model of the mobile terminal 1 by a user who has a long time to execute a game application program on the mobile terminal 1. In FIG. 2A, the usage category and the usage time are associated with each other. The usage category is information indicating the usage type of the application program used by the user in one day. The usage time is a time during which the user operates the portable terminal 1 using an application program of each usage category during the day. FIG. 2A shows an example in which the user uses an application program such as a game, browser, SNS, and video browsing for a total of 180 minutes.

  FIG. 2B shows that the user using the mobile terminal 1 uses a plurality of application programs (game A to game D, etc.) belonging to the game category. FIG. 2C shows the details of the operation executed while the mobile terminal 1 executes the application program of the game A, and the breakdown of the time when the operation content is executed.

  If the current consumption per unit time (for example, 1 minute) in each operation content shown in FIG. 2C is known, the mobile terminal 1 in the usage model shown in FIG. 2 is multiplied by the execution time of each operation content. Can calculate the current consumption when the application program of the game A is executed. If the consumption current is calculated for all application programs, the estimated daily consumption current of the portable terminal 1 of the usage model shown in FIG. 2 can be calculated. And when the portable terminal 1 operate | moves with a battery, when the portable terminal 1 is used with the usage model shown in FIG. 2 after fully charging a battery based on the relationship between the current capacity of the battery and the estimated current consumption In addition, the time until the remaining battery level becomes zero (hereinafter referred to as the battery duration) can be specified.

  Therefore, the portable terminal 1 according to the present embodiment executes the current consumption calculation program, so that each component is actually operating within a unit time for executing each operation content (hereinafter referred to as actual operation time). ) And the current consumption per unit time in each operation content is calculated based on the known current consumption and the actual operation time when each component operates. Then, the mobile terminal 1 can calculate the entire current consumption and battery duration of the mobile terminal 1 in the usage model based on the execution time of each operation content in the usage model for which the current consumption is calculated. . By doing in this way, the terminal evaluator who wants to check the current consumption of the mobile terminal 1 calculates the current consumption and the battery duration of the mobile terminal 1 in a short time without connecting the mobile terminal 1 to the current measuring device. be able to.

  FIG. 3 is a diagram for explaining the contents of the operation performed by the mobile terminal 1 in the second usage model. FIG. 3 shows a usage model of the mobile terminal 1 by a user who takes a long time to execute a browser application program in the mobile terminal 1. As described above, since the breakdown of the execution time of each operation content varies depending on the assumed usage model, the current consumption calculation program allows the terminal evaluator to select the usage model for which the current consumption is to be calculated. ing.

  The consumption current calculation program may allow the terminal evaluator to select one or more operation contents to be included in the usage model from a plurality of preset operation contents and set the execution time of each selected operation content. . By doing so, the terminal evaluator can easily set an arbitrary usage model.

  FIG. 4 is a diagram illustrating a relationship between elapsed time and current consumption in an operation in which the mobile terminal 1 displays a website screen by executing a browser application program. As shown in FIG. 4, the mobile terminal 1 consumes every time based on each component while the application program is executed using the operation content determination program and the current consumption of each component. The current can be calculated. The current consumption shown in FIG. 4 indicates a change in the current value measured while actually operating the browser. It can be seen that the current consumption fluctuates with the passage of time, and that the current consumption increases at the timing when the browser starts and when the page to be displayed changes.

  FIG. 5 is an enlarged view of the relationship between elapsed time and current consumption shown in FIG. In FIG. 5A, it can be seen that the current consumption varies finely microscopically, but macroscopically changes the current consumption stepwise. The current consumption of the portable terminal 1 changes in a stepped manner in this way because the average value within a predetermined time differs for each operation content.

  FIG. 5B is a diagram showing a tendency of a change in the average value (for example, moving average value) of current consumption calculated every predetermined time. In FIG. 5B, the calculation period of the consumption current shown in FIG. 5A is based on which of the plurality of consumption current ranges P1 to P7 includes the average consumption current value. E is divided into a plurality of periods. The period C is divided into three periods C1 to C3. Based on the consumption current change data shown in FIG. 5A, the portable terminal 1 calculates the start time and end time of each period shown in FIG. 5B (that is, the change timing of the operation content) for each period. Output in association with the average value of current consumption.

The terminal evaluator specifies what operation was performed in the periods A to E based on the operation state of the mobile terminal 1 when the change in current shown in FIG. Thus, the operation content included in the usage model can be determined. For example, the terminal evaluator determines that the mobile terminal 1 has a period A when the application is activated, a period B is when the activation process is performed, a period C is when the scroll display is performed, a period D is when the page is transitioned, a period E is when the display is standby The operation content necessary for measuring the current consumption can be determined.
Hereinafter, the configuration and operation of the mobile terminal 1 will be described in detail.

[Configuration of mobile terminal 1]
FIG. 6 is a diagram illustrating a configuration of the mobile terminal 1 of the present embodiment. The mobile terminal 1 has a plurality of components that consume current. Specifically, the mobile terminal 1 includes a battery 11, a display 12, a touch panel 13, a communication unit 14, a sensor 15, a camera 16, a GPU (Graphic Processing Unit) 17, a ROM 18, a RAM 19, CPU 20. The display 12, the touch panel 13, the communication unit 14, the sensor 15, the camera 16, the GPU 17, the ROM 18, the RAM 19, and the CPU 20 are connected to each other by signal lines such as a data bus and an address bus.

  The battery 11 supplies a current for operating each part of the mobile terminal 1. The battery 11 is, for example, a lithium ion battery, a lithium polymer battery, or a nickel cadmium battery, and can be charged by being connected to an external power source.

The display 12 is, for example, a liquid crystal display (LCD) or an organic EL (Electroluminescence) display. The display 12 displays information based on the control of the CPU 20.
The touch panel 13 is provided so as to overlap the display 12 and detects a position on the display touched by the user. The touch panel 13 notifies the CPU 20 of coordinate information indicating the position touched by the user.

  The communication unit 14 is a wireless communication interface such as LTE (Long Term Evolution) and BLE (Bluetooth (registered trademark) Low Energy). The communication unit 14 transmits / receives data to / from a base station of the mobile terminal network or transmits / receives data to / from other communication terminals via the BLE based on the control of the CPU 20.

The sensor 15 is, for example, a gravity sensor or a temperature sensor that detects the state of the mobile terminal 1. The sensor 15 notifies the CPU 20 of a signal indicating the detected state.
The camera 16 includes a lens and an image sensor, and generates a captured image of the captured subject based on the control of the CPU 20. The camera 16 inputs the generated captured image to the GPU 17.
The GPU 17 executes various image processes based on the control of the CPU 20.

  The ROM 18 is, for example, an EEPROM (Electrically Erasable Programmable Read-Only Memory), and is a writable nonvolatile memory. A program executed by the CPU 20 is stored. The RAM 19 temporarily stores various data used when the CPU 20 executes the program.

  The ROM 18 stores various setting data used when the CPU 20 executes the program. For example, the ROM 18 stores the type of usage model and a plurality of operation contents included in each usage model in association with each other. Specifically, the ROM 18 stores an operation content table associating each operation content and execution time in each usage model shown in FIGS. 2 and 3.

  In addition, the ROM 18 stores element-by-element current consumption, which is current consumption when each of the plurality of components of the mobile terminal 1 operates, in association with each of the plurality of components. The current consumption by element is the current consumption per unit time of each component and is provided as a current consumption profile by an OS (Operating System) such as Android (registered trademark). The ROM 18 stores, for example, element-by-element current consumption per unit time when each component operates in a mode that consumes the most current. FIG. 7 shows an example of current consumption by element of each component. When each component has a plurality of operation modes with different current consumption, the ROM 18 may store the current consumption for each component in association with the operation mode of each component. The value of the current consumption by element stored in the ROM 18 is a current value measured in advance at the time of development of the portable terminal 1.

  The CPU 20 controls each unit of the portable terminal 1 by executing a program stored in the ROM 18. The CPU 20 functions as an execution unit 201, an operation state specifying unit 202, a calculation unit 203, a classification unit 204, and an output unit 205 by executing a program.

  The execution unit 201 executes various application programs. The execution unit 201 executes an operation content determination program in accordance with the operation of the terminal evaluator, and executes an application program (hereinafter referred to as a specific target application) for specifying the operation content using the operation content determination program. To do.

  The operation state identification unit 202 identifies the operation state of each component of the mobile terminal 1 while the execution unit 201 is executing the identification target application. The operation state specifying unit 202 specifies, for example, what operation each of the plurality of constituent elements of the mobile terminal 1 is performing via the OS while the execution unit 201 is executing the specification target application. The operation state specifying unit 202 notifies the calculation unit 203 of operation state information indicating the specified operation in association with information indicating time. When the component has a plurality of operation modes with different current consumption, the operation state specifying unit 202 calculates operation state information indicating the operation mode being executed by each component in association with information indicating time. 203 is notified.

  The calculation unit 203 calculates the overall consumption current of the mobile terminal 1 calculated based on the operation state and the element-based consumption current in association with the elapsed time from when the execution unit 201 starts executing the application program. . For each elapsed time, the calculation unit 203 calculates the overall current consumption of the mobile terminal 1 by adding the element-specific current consumption corresponding to the components operating at the elapsed time among the plurality of components. The classifying unit 204 is notified of the elapsed time and the total consumption current It in association with each other. For example, the calculation unit 203 may calculate the consumption current of each component within a predetermined period by multiplying the actual operation time during which each component is operating within a predetermined period by the consumption current for each element. Good.

  Note that the calculation unit 203 determines the current value consumed by the operation state specifying unit 202 or the calculation unit 203 when the mobile terminal 1 executes the operation content determination program, as well as the operation state specified by the operation state specifying unit 202 and the consumption by element. By subtracting the current consumption calculated based on the current, the overall current consumption of the mobile terminal 1 is corrected. By doing in this way, the influence which the current consumed when CPU20 runs the operation content determination program has on the calculation result of the consumption current of the portable terminal 1 can be excluded. The accuracy of the calculated consumption current is improved.

  The calculation unit 203 calculates an average value of current consumption every predetermined time. For example, the calculation unit 203 calculates a moving average value of current consumption. The calculation unit 203 obtains a smoothed change characteristic of the consumption current that does not include a short-time fluctuation of the consumption current that occurs regardless of the switching of the operation content by calculating the moving average value of the consumption current. it can. The calculation unit 203 may calculate the moving average value based on the time set by the terminal evaluator. By doing in this way, the terminal evaluator can adjust the smoothing degree of the consumption current to a desired level at which the change timing of the operation content can be easily specified. The calculation unit 203 notifies the classification unit 204 of the calculated average value of current consumption.

  The classification unit 204 classifies the current consumption calculated by the calculation unit 203 into a plurality of current ranges. For example, the calculation unit 203 identifies which current range the smoothed current consumption value (that is, the average current consumption value) is included in the current ranges P0 to P7 illustrated in FIG. By doing so, the current consumption is classified into one of a plurality of current ranges. Then, the classification unit 204 identifies the change timing when the operation content of the mobile terminal 1 has changed based on the timing when the average value of the current consumption has changed, and notifies the output unit 205 of the specified change timing.

  The output unit 205 outputs information indicating the change characteristic of the consumption current subjected to the smoothing process in association with the elapsed time. For example, the output unit 205 outputs the average value of the consumption current calculated by the calculation unit 203, that is, the smoothed consumption current value in association with the elapsed time. Further, the output unit 205 outputs information indicating a current range in which current consumption is classified among a plurality of current ranges in association with the elapsed time. For example, the output unit 205 outputs information indicating the relationship between elapsed time and current consumption as shown in FIG. The format of the information output by the output unit 205 is arbitrary, and may be a graph format as shown in FIG. 5B or a table format including elapsed time and current consumption values.

  FIG. 8 is a diagram illustrating the relationship between the information output by the output unit 205 and the operation content specified by the user. FIG. 8A shows information indicating the relationship between the elapsed time output by the output unit 205 and the current consumption. In FIG. 8 (a), values of time and current consumption are not shown, but the output unit 205 outputs at least time information.

  In FIG. 8B, the terminal evaluator was executing the current consumption change time indicated by the information output by the output unit 205 as shown in FIG. 8A and the operation content determination program during execution. The operation content specified by collating with the transition time of the operation content in the specific target application is shown. Thus, since the portable terminal 1 outputs the period from which the tendency of consumption current differs easily by executing the operation content determination program, the terminal evaluator can easily determine the operation content.

[Operation Flowchart of CPU 20]
FIG. 9 is a flowchart of the operation in which the CPU 20 calculates the current consumption.
First, when the terminal evaluator starts the operation content determination program and the specific target application (S11), the execution unit 201 executes the specific target application (S12).

  While the execution unit 201 is executing the identification target application, the operation state identification unit 202 identifies the operation state of each component (S13). Subsequently, the calculation unit 203 calculates the consumption current by adding the element-specific consumption currents of the operating components based on the operation states of the respective components specified by the operation state specifying unit 202 (S14). .

  Subsequently, the calculation unit 203 corrects the current consumption by subtracting the current consumed by the operation state specifying unit 202 or the calculation unit 203 when the mobile terminal 1 executes the operation content determination program from the calculated current consumption. (S15). Subsequently, the calculation unit 203 smoothes the change in the consumption current by calculating the moving average value of the calculated consumption current (S16).

  Subsequently, the calculation unit 203 classifies the consumption current based on where the smoothed consumption current value is included in the predetermined consumption current range (S17), and specifies the timing at which the consumption current changes (S18). . Then, the output unit 205 outputs information indicating the relationship between elapsed time and current consumption (S19).

[Modification]
In the above description, the example in which the classification unit 204 specifies the change timing of the operation content of the mobile terminal 1 based on the average value of the current consumption has been described. Not limited to. The classification unit 204 may specify the change timing of the operation content based on a combination of a plurality of constituent elements specified as being operated by the operation state specifying unit 202.

  For example, the classifying unit 204 identifies the actual operation time during which each component operates for the most recent past predetermined period, and determines the change timing of the operation content based on the combination of the lengths of the identified actual operation time. Identify. Since the combinations of the actual operation times of the plurality of components are different for each operation content, the classification unit 204 can specify the change timing of the operation content based on the combination of the actual operation times of the plurality of components. By using a combination of a plurality of components in this way, the classification unit 204 includes the average value of current consumption in the same current range, for example, C1, C2, and C3 shown in FIG. 5B. Even if it is, it becomes possible to specify the change timing of operation | movement content.

  The output unit 205 outputs information indicating a combination of a plurality of components that the operation state specifying unit 202 specifies as operating in association with the elapsed time. By doing in this way, since the terminal evaluator can specify the timing at which the internal operation has greatly changed even if the measured current consumption in the mobile terminal 1 is the same, other types of mobile terminals can be used using the usage model. The accuracy when calculating the current consumption can be improved.

[Effects of the mobile terminal 1 of the present embodiment]
As described above, in the mobile terminal 1, the calculation unit 203 is based on the operation state of each of the plurality of components and the current consumption by element while the execution unit 201 executes the application program. The classifying unit 204 classifies the calculated current consumption into one of a plurality of current ranges. Then, the output unit 205 outputs the current consumption classified by the classification unit 204 in association with the elapsed time. By doing in this way, since the terminal evaluator can grasp what operation with different current consumption is being performed inside the mobile terminal 1, the accuracy of the usage model used for calculating the power consumption It becomes possible to improve.

  The calculation unit 203 calculates an average value of current consumption, the classification unit 204 classifies the current consumption based on the average value, and the output unit 205 outputs the average value and the change timing of the average value in association with the elapsed time. . By doing in this way, since it is not influenced by the short-time fluctuation | variation of consumption current, it becomes easy for a terminal evaluator to grasp | ascertain correctly the timing at which the operation content which affects consumption current changes.

  The classification unit 204 can also specify the change timing based on a combination of a plurality of components in operation. By doing in this way, since the terminal evaluator can specify the timing at which the internal operation has greatly changed even if the measured current consumption in the mobile terminal 1 is the same, other types of mobile terminals can be used using the usage model. The accuracy when calculating the current consumption can be improved.

  Further, the calculation unit 203 subtracts the current consumed when the portable terminal 1 executes the operation content determination program from the consumed current calculated based on the operation state and the element-based consumption current, thereby obtaining the portable terminal. Since the entire current consumption of 1 is calculated, it is possible to suppress the influence on the current consumption caused by executing the operation content determination program.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above embodiment. In particular, the specific embodiments of the distribution / integration of the devices are not limited to those illustrated above, and all or a part thereof may be added in arbitrary units according to various additions or according to functional loads. It can be configured functionally or physically distributed and integrated.

  For example, in the above description, a mobile terminal in which the electronic device has a battery is illustrated, but the electronic device is not limited to the mobile terminal. The present invention can be applied to any electronic device, and is also effective when calculating current consumption in home appliances and the like that do not have a battery.
