  However, in the above technique, power saving control may not be executed until contact with the human body is detected, and power saving control may not be executed even if the human body touches other than the surface of the terminal on which the touch sensor or the like is arranged. Therefore, power saving control is not appropriate.

[overall structure]
FIG. 1 is a diagram illustrating an overall configuration example of a mobile terminal according to the first embodiment. A mobile terminal 10 shown in FIG. 1 is an example of a terminal such as a smartphone or a mobile phone. A mobile terminal 10 shown in FIG. 1 is equipped with a plurality of electronic devices inside the terminal. Examples of electronic devices are a processor, a power amplifier, a power supply circuit, a backlight circuit, and the like.

  As shown in FIG. 1, the mobile terminal 10 generates a heat generating portion A when an electronic device mounted on the mobile terminal 10 operates to generate heat. The temperature of the heat generating part A tends to increase as the power consumption of the electronic device or the like increases. However, when the human body 50 or the like is touched, the heat is absorbed by the human body and the temperature decreases. Utilizing this tendency, the mobile terminal 10 executes power saving control for suppressing power consumption when detecting contact with a human body.

  Specifically, the mobile terminal 10 stores the correspondence between the power consumption of the mobile terminal 10 and the temperature of the mobile terminal 10 measured in a state where the mobile terminal 10 is not in contact with the human body. The mobile terminal 10 measures the power consumption of the mobile terminal 10 and the temperature of the mobile terminal 10 at the time of the power consumption. The mobile terminal 10 detects contact of the human body when the measured temperature is lower than the temperature correlated with the measured power consumption. The mobile terminal 10 executes power saving control that suppresses power consumption when contact with a human body is detected.

  Thus, the mobile terminal 10 stores in advance the correlation between the reference power consumption and the temperature, and when the relationship between the periodically measured power consumption and the temperature at that time does not satisfy the correlation, the mobile terminal 10 Is detected to reduce power consumption. Therefore, the mobile terminal 10 can execute appropriate power saving control as the temperature rises.

  In the above example, the power saving control is performed on the mobile terminal 10 itself using the correlation between the power consumption of the entire mobile terminal 10 and the temperature. However, the present invention is not limited to this. For example, the same control can be executed for each electronic device mounted on the mobile terminal 10. Below, the example which performs power saving control about each electronic device used as a heat source is demonstrated. The correlation is an example of a correspondence relationship.

  The control unit 20 is a processing unit that controls the entire mobile terminal 10 and is, for example, a processor. The control unit 20 reads and executes a program stored in the storage unit 18 and executes various processes.

[Hardware location configuration]
Next, a mounting example of the hardware configuration shown in FIG. 2 will be described. FIG. 3 is a diagram illustrating an example of the positional relationship of hardware. In FIG. 3, the control unit 20 is described as an example of the heat source. However, the control unit 20 is merely an example, and the heat source is not limited.

  As shown in FIG. 3, the control unit 20, the power consumption measuring unit 16, and the temperature sensor unit 14 are mounted on the substrate 10a. The control unit 20 is an example of a heat source, and generates heat by consuming power and executing processing. The temperature sensor unit 14 is a sensor that periodically measures the temperature of the control unit 20 serving as a heat source. The temperature sensor unit 14 is installed in the vicinity of the control unit 20 serving as a heat source. For example, the temperature sensor unit 14 is installed adjacent to the control unit 20 on the substrate 10a. The

  The power consumption measuring unit 16 is a circuit that periodically measures the power consumption of the control unit 20 serving as a heat source. The power consumption measuring unit 16 may be mounted for each heat source, and one unit is set in the mobile terminal 10 to consume each heat source. Electric power can also be measured with a single unit.

[Function configuration]
Next, the functional configuration of the mobile terminal 10 will be described. FIG. 4 is a functional block diagram illustrating a functional configuration of the mobile terminal according to the first embodiment.

  As illustrated in FIG. 4, the mobile terminal 10 includes a correlation DB 18 a, a reference value DB 18 b, a preprocessing unit 21, a recording unit 22, a measurement unit 23, a calculation unit 24, a comparison unit 25, and an execution unit 26. The correlation DB 18a and the reference value DB 18b are a database stored in the storage unit 18 or the like. The preprocessing unit 21, the recording unit 22, the measurement unit 23, the calculation unit 24, the comparison unit 25, and the execution unit 26 are an example of a part of an electronic circuit included in the control unit 20 and a process executed by the control unit 20.

  The correlation DB 18a shows the correlation between the power consumption of the electronic device and the temperature of the electronic device measured in a state where each electronic device is not in contact with the human body 50 for each electronic device that is a heat source in the mobile terminal 10. It is a database to memorize.

  For example, the correlation DB 18a stores a correlation that determines the temperature of the electronic device based on the power consumption of the electronic device. Further, the correlation DB 18a may store a graph in which the horizontal axis is power (W) and the vertical axis is temperature (° C.) as a correlation, and stores a table in which power consumption and temperature are associated with each other. You may do it. The information stored here is stored by the preprocessing unit 21.

  The reference value DB 18b is a database that stores, for each electronic device that is a heat source, the temperature of the electronic device that is measured under a condition that power consumption is a predetermined value or less as a reference temperature. For example, the reference value DB 18b stores the temperature of the electronic device when the power consumption is 0 or the power consumption is 10 mW or less. Note that the information stored here is appropriately updated by the recording unit 22.

  For each electronic device that is a heat source in the mobile terminal 10, the preprocessing unit 21 correlates the power consumption of the electronic device and the temperature of the electronic device measured in a state where each electronic device is not in contact with the human body 50. Is generated and stored in the correlation DB 18a. That is, the pre-processing unit 21 generates a reference power consumption and temperature relationship for each electronic device before the mobile terminal 10 is shipped.

  Specifically, the pre-processing unit 21 measures the power consumption of the electronic device and the temperature of the electronic device at that time in a state where the human body 50 is not in contact with each electronic device. That is, the preprocessing unit 21 acquires the power consumption measured by the power consumption measurement unit 16 and the temperature value measured by the temperature sensor unit 14 at that time from each unit. And the pre-processing part 21 produces | generates the table which matched power consumption and temperature as a correlation.

  In addition, the preprocessing unit 21 generates, as a correlation, a graph in which measured values are plotted with the horizontal axis representing power consumption (W) and the vertical axis representing temperature (° C.). That is, the pre-processing unit 21 generates a correlation of the temperature increase (ΔTm) with respect to the power consumption.

  Here, a correlation generation example will be described as an example. FIG. 5 is a diagram for explaining advance preparation. In addition, the numerical value shown here is an example and can be arbitrarily changed.

  As shown in FIG. 5, the pre-processing unit 21 generates a graph Y connecting points determined by the measured power consumption and temperature, with the temperature value when the power consumption is 0 W as an initial value. This graph Y shows the correlation between actual power consumption and actual temperature.

  Here, the temperature value as the initial value of the graph Y is not 0 but A ° C. even though the power consumption is 0 W. This is because it is influenced by the environmental temperature when the correlation is generated. Therefore, in order to prevent the correlation from changing due to the environmental temperature, the pre-processing unit 21 sets the temperature value when the power consumption is 0 W as 0, and calculates the temperature increase (ΔTm) when the power consumption increases. A correlation is generated by recording it as a temperature value.

  Specifically, the preprocessing unit 21 generates a graph Z shown in FIG. 5 by plotting a value obtained by subtracting the initial value (A ° C.) from the actually measured value as a temperature value. That is, the pre-processing unit 21 generates, as a correlation, a graph Z obtained by shifting the graph Y generated with the actually measured values by A ° C. in the negative direction of the Y axis (temperature).

  The recording unit 22 is a processing unit that measures, for each electronic device, the temperature of the electronic device measured under the condition that the power consumption is equal to or less than a predetermined value, and stores the temperature in the reference value DB 18b as a reference temperature. Specifically, the recording unit 22 periodically acquires the power consumption of each electronic device from the power consumption measurement unit 16, and is measured by the temperature sensor unit 14 when the acquired power consumption is 0 or 10 mW or less. The temperature value “Tb” is acquired from the temperature sensor unit 14 and stored in the reference value DB 18b. That is, the temperature value “Tb” at this time is the environmental temperature.

  The recording unit 22 starts processing after power is turned on after the mobile terminal 10 is shipped, and executes the above processing as needed until the power is turned off. Moreover, the numerical value of the power consumption shown here is an example, and can be arbitrarily changed.

  The measurement unit 23 is a processing unit that measures the power consumption of the electronic device and the temperature of the electronic device during power consumption measurement for each electronic device. Specifically, the measurement unit 23 periodically acquires the power consumption “S (W)” of each electronic device from the power consumption measurement unit 16. Furthermore, the measurement unit 23 acquires the temperature value “Tr” measured by the temperature sensor unit 14 from the temperature sensor unit 14 when the acquired power consumption is a predetermined value (greater than 0 or greater than 10 mW).

  Then, the measurement unit 23 outputs the acquired power consumption “S (W)” and the temperature value “Tr” to the calculation unit 24. Note that the measurement unit 23 outputs each value to the calculation unit 24 every time the power consumption and the temperature value are acquired. In addition, the numerical value shown here is an example.

  The calculation unit 24 is a processing unit that calculates a difference between the temperature value measured by the measurement unit 23 and a reference value. For example, when the power consumption “S (W)” and the temperature value “Tr” are input from the measurement unit 23 for the electronic device A, the calculation unit 24 is associated with the electronic device A and stored in the reference value DB 18b. The reference value “Tb” is read out.

  Then, the calculation unit 24 calculates a difference value “ΔTm” obtained by subtracting the reference value “Tb” from the measured temperature value “Tr”. Thereafter, the calculation unit 24 outputs the calculated difference value “ΔTm” and the power consumption “S (W)” input from the measurement unit 23 to the comparison unit 25.

  For each electronic device, the comparison unit 25 is based on the relationship between the difference value calculated by the calculation unit 24 and the power consumption measured by the measurement unit 23, and the correlation stored in the correlation DB 18a. It is a processing part which detects the contact of.

  Specifically, the comparison unit 25 uses the human body 50 when the relationship between the difference value calculated using the temperature at the time of power consumption measured by the measurement unit 23 and the power consumption value does not satisfy the correlation. It is determined that there is no contact, and if the correlation is satisfied, it is determined that the human body 50 is not in contact. That is, the comparison unit 25 determines that the human body 50 is in contact when the temperature at the time of power consumption measured by the measurement unit 23 is lower than the temperature associated with the power consumption in the correspondence relationship generated in advance. .

  In the above example, the comparison unit 25 specifies the correlation value “Tc” when the power consumption is “S (W)” measured by the measurement unit 23, from the correlation stored in the correlation DB 18a. When the difference value “ΔTm” <correlation value “Tc”, the comparison unit 25 determines that the human body 50 is in contact. On the other hand, when the difference value “ΔTm” = correlation value “Tc”, the comparison unit 25 determines that the human body 50 is not in contact.

  This will be specifically described with reference to FIG. FIG. 6 is a diagram for explaining a comparative example with the correlation. A graph Z (solid line) illustrated in FIG. 6 is a graph in which the temperature “correlation value: Tc” acquired by the preprocessing unit 21 at each power consumption is plotted, and indicates a correlation stored in the correlation DB 18a. The graph G (dotted line) is a graph in which the difference value “ΔTm = Tr−Tb” calculated for each power consumption measured by the measurement unit 23 is plotted, and the power consumption of the operating electronic device is increased. The accompanying temperature change is shown.

  FIG. 6 shows an example in which the comparison unit 25 plots the difference value “ΔTm” measured periodically. In this example, until the power consumption exceeds “P (W)”, the difference value “ΔTm” and the correlation value “Tc” match, and when the power consumption exceeds “P (W)”, the difference The value “ΔTm” is smaller than the correlation value “Tc”.

  Therefore, the comparison unit 25 does not detect the contact of the human body 50 until the power consumption exceeds “P (W)”, and detects the contact of the human body 50 when the power consumption exceeds “P (W)”. . Then, the comparison unit 25 outputs information on the electronic device in which the contact of the human body 50 is detected to the execution unit 26.

  The execution unit 26 is a processing unit that executes power saving control that suppresses power consumption of the electronic device in which contact with the human body 50 is detected. Specifically, the execution unit 26 executes power saving control corresponding to each electronic device. For example, the execution unit 26 executes processor clock control, camera unit 17 stop, charge stop, screen brightness reduction, Wi-Fi (Wireless Fidelity) stop, and the like.

[Process flow]
FIG. 7 is a flowchart illustrating the flow of processing according to the first embodiment. Here, it is assumed that the preprocessing by the preprocessing unit 21 has been completed, and the correlation between power consumption and temperature is stored in the correlation DB 18a for each electronic device. FIG. 7 illustrates the flow of processing for one electronic device, but the same processing is executed for each electronic device.

  As shown in FIG. 7, when the recording unit 22 and the measurement unit 23 regularly monitor the power consumption of the corresponding electronic device and the power consumption is not 0 (S101: No), the measurement unit 23 The temperature “Tr” is measured (S102). At this time, the measurement unit 23 also measures the power consumption of the corresponding electronic device.

  Subsequently, the calculation unit 24 reads the reference value “Tb” of the corresponding electronic device from the reference value DB 18b, and calculates a rise temperature “ΔTm = Tr−Tb” that is a difference value from the reference value (S103). Then, the comparison unit 25 identifies the correlation value “Tc” corresponding to the measured power consumption according to the correlation stored in the correlation DB 18a, and compares the increased temperature “ΔTm” with the correlation value “Tc”. (S104).

  Then, when the comparison unit 25 determines that the rising temperature “ΔTm” = correlation value “Tc” (S105: No), the comparison unit 25 determines that there is no contact with the human body 50 (S106). Thereafter, the execution unit 26 performs function restriction when there is no human body contact (S107). For example, the execution unit 26 continuously executes the currently executed process, or when the function is being suppressed, cancels the suppression and executes a normal process. Thereafter, the steps after S101 are periodically repeated.

  On the other hand, when the temperature rise is “ΔTm” <correlation value “Tc” (S105: Yes), the comparison unit 25 determines that the human body 50 is in contact (S108). Then, the execution unit 26 performs function restriction when there is a human body contact (S109).

  In S101, the recording unit 22 and the measurement unit 23 regularly monitor the power consumption of the corresponding electronic device. If the power consumption is 0 (S101: Yes), the recording unit 22 determines that the temperature “ “Tr” is measured (S110). Then, the recording unit 22 stores the measured temperature as the reference value “Tr” in the reference value DB 18b (S111).

[effect]
As described above, the mobile terminal 10 detects a human body contact only by what is normally mounted inside the mobile terminal 10 without providing dedicated sensors for detecting a human body contact on the surface of the housing. Can do. Accordingly, the mobile terminal 10 can detect a human body contact even in a place where a conventional human body contact detection sensor cannot be disposed.

  In addition, since the mobile terminal 10 generates a correlation between power consumption and temperature with a temperature when the power consumption is equal to or lower than a predetermined value as 0 and a rise in power consumption as a temperature value before shipping, It is possible to generate a correlation considering the influence of temperature. Therefore, the mobile terminal 10 can accurately determine whether or not the power consumption and temperature during operation satisfy a reference correlation generated in advance.

  Moreover, since the mobile terminal 10 can execute appropriate power saving control for the entire mobile terminal 10 and can execute appropriate power saving control for each heat source in the mobile terminal 10, a human body such as low-temperature burns can be obtained. The influence which it has on can be suppressed. In addition, power consumption of the entire terminal can be suppressed.

  Although the embodiments of the present invention have been described so far, the present invention may be implemented in various different forms other than the embodiments described above.

[Correlation]
In the above-described embodiment, the example in which it is determined whether or not the correlation value “Tc” specified by the correlation and the rising temperature “ΔTm” that is the difference value coincide with each other has been described. Absent. For example, the correlation value “Tc” may have a certain width. For example, the mobile terminal 10 may determine that there is no contact with the human body 50 when the correlation value “Tc” to ± 2 ° C. is an allowable range and the rising temperature “ΔTm” is within this range. it can.

  FIG. 8 is a diagram illustrating an example in which the correlation is given a width. As illustrated in FIG. 8, the pre-processing unit 21 has a graph Z1 in which the correlation value “Tc + 2 ° C.” is plotted and a correlation value “Tc−2 ° C.” in addition to the graph Z indicating the correlation in which the correlation value “Tc” is plotted. Is generated, and these three graphs are stored in the correlation DB 18a as correlations.

  Then, the comparator 25 plots the rising temperature “ΔTm” every time the rising temperature “ΔTm” is calculated (see graph G1 in FIG. 8). In the example of FIG. 8, the difference value “ΔTm” is in the range of the correlation value “Tc ± 2 ° C.” until the power consumption exceeds “Q (W)”, and the power consumption exceeds “Q (W)”. Then, the difference value “ΔTm” becomes smaller than the correlation value “Tc−2 ° C.”.

  Therefore, the comparison unit 25 does not detect the contact of the human body 50 until the power consumption exceeds “Q (W)”, and detects the contact of the human body 50 when the power consumption exceeds “Q (W)”. . As described above, the mobile terminal 10 can improve the detection accuracy of the human body 50 by giving a wide range of the correlation in consideration of errors due to the measurement environment of the preprocessing.

  Moreover, although the example using the graphed correlation as an example of the correspondence has been described in the above embodiment, the present invention is not limited to this. For example, the preprocessing unit 21 can generate a table in which power consumption and temperature are associated with each other and store the table in the correlation DB 18a. In this way, any format may be used as long as the correspondence relationship between power consumption and temperature is characterized.

[Position completion]
For example, the mobile terminal 10 can supplement the detection of the human body 50 using a touch panel. Specifically, the mobile terminal 10 can detect an operation on an electronic device located near the touch panel or an electronic device in contact with the touch panel using the touch panel. For this reason, in addition to the said process, the mobile terminal 10 can detect the contact of the human body 50 correctly by using the detection result of a touch panel.

[system]
Further, each configuration of the illustrated apparatus does not necessarily need to be physically configured as illustrated. That is, it can be configured to be distributed or integrated in arbitrary units. Further, all or any part of each processing function performed in each device may be realized by a CPU and a program analyzed and executed by the CPU, or may be realized as hardware by wired logic.

  In addition, among the processes described in this embodiment, all or part of the processes described as being performed automatically can be performed manually, or the processes described as being performed manually can be performed. All or a part can be automatically performed by a known method. In addition, the processing procedure, control procedure, specific name, and information including various data and parameters shown in the above-described document and drawings can be arbitrarily changed unless otherwise specified.

  The mobile terminal 10 described in the present embodiment can execute the same function as the process described in FIG. 4 and the like by reading and executing the power control program. For example, the mobile terminal 10 develops a program having the same functions as those of the preprocessing unit 21, the recording unit 22, the measurement unit 23, the calculation unit 24, the comparison unit 25, and the execution unit 26 in the memory. And the mobile terminal 10 performs the process which performs the process similar to the pre-processing part 21, the recording part 22, the measurement part 23, the calculation part 24, the comparison part 25, and the execution part 26, and is the said Example. Similar processing can be performed.

  This program can be distributed via a network such as the Internet. The program can be executed by being recorded on a computer-readable recording medium such as a hard disk, a flexible disk (FD), a CD-ROM, an MO, and a DVD, and being read from the recording medium by the computer.
