Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
These and other aspects of embodiments of the invention will be apparent with reference to the following description and attached drawings. In the description and drawings, particular embodiments of the invention have been disclosed in detail as being indicative of some of the ways in which the principles of the embodiments of the invention may be practiced, but it is understood that the scope of the embodiments of the invention is not limited correspondingly. On the contrary, the embodiments of the invention include all changes, modifications and equivalents coming within the spirit and terms of the claims appended hereto.
The first embodiment is as follows:
referring to fig. 1, a method for controlling a sensor according to a first embodiment of the present invention is applied to a mobile terminal, and the method includes the following steps:
s101, acquiring the current endurance time corresponding to the mobile terminal in the current state, and acquiring the predicted time point of the mobile terminal at the next charging time.
In this embodiment, the mobile terminal is at least provided with a fingerprint sensor, an ambient light sensor, a proximity sensor, a gyroscope sensor, an infrared sensor, a magnetic field sensor, a hall sensor, and a gravity sensor. It should be noted that the sensors provided in the mobile terminal are not limited to the above-mentioned sensors, and the actual application requirements are subject to specific criteria.
Additionally, before the step one, the method comprises the following steps:
and S001, judging whether the mobile terminal is in a charging state.
And S002, if not, judging whether the current mode of the mobile terminal is the outdoor mode.
The outdoor mode is judged according to parameters acquired by an ambient light sensor, a gyroscope sensor or an infrared sensor.
And S003, if so, acquiring the current endurance time corresponding to the mobile terminal in the current state, and generating a request information input box, wherein the request information input box is used for receiving the predicted time point of the next charging time of the mobile terminal, which is input by a user.
It can be understood that when the mobile terminal detects that the user is in the outdoor mode, the mobile terminal cannot be effectively charged in time in the outdoor mode, and therefore early warning needs to be performed on the endurance time in advance and corresponding measures need to be taken.
Specifically, in this embodiment, the mobile terminal obtains the current endurance time corresponding to the current state, and then the user is required to input the predicted time point of the next charging time, that is, the predicted charging time point of the user. For example, the current endurance of the mobile terminal in the current state is 6h, and the expected time point of the next charging time of the mobile terminal, which receives all the user inputs, is 8h later.
And S102, judging whether the predicted time point of the next charging moment of the mobile terminal is within the interval range corresponding to the current endurance time.
As described above, for example, the current endurance of the mobile terminal in the current state is 6h, and the expected time point of the next charging time of the mobile terminal, which receives all the user inputs, is 8h later. Therefore, the predicted time point of the next charging time of the mobile terminal is not within the interval range corresponding to the current endurance time.
And S103, if not, calculating to obtain a difference value of the time to be continued according to the predicted time point of the next charging moment of the mobile terminal and the end point value of the current time to be continued, and searching and determining to obtain a corresponding level of the time to be continued in a preset mapping table according to the difference value of the time to be continued.
It can be understood that, if the predicted time point of the next charging time of the mobile terminal is not within the range of the interval corresponding to the current endurance time, it indicates that if the mobile terminal does not perform the power optimization in time, the predicted time point of the next charging time cannot be maintained continuously.
Further, a difference value of the to-be-continued flight time is calculated according to the predicted time point of the next charging time of the mobile terminal and the terminal value of the current continuation of the flight time. For example, as can be seen from the above example, the difference between the waiting times is 2 h. Further, after the waiting time is obtained, the corresponding cruising demand grade can be obtained by searching and determining in the preset mapping table according to the determined waiting time. In the present embodiment, the cruising demand level described above is set to ten levels.
And S104, acquiring sensor information corresponding to all sensors in the activated state in the mobile terminal.
The sensor information at least comprises sensor types, sensor unit power consumption and the number corresponding to each type of sensor.
As described in step S103, since the predicted time point of the next charging time of the mobile terminal is not within the interval range corresponding to the current endurance time, it is described that if the power optimization is not performed in time, the predicted time point of the next charging time cannot be maintained, and therefore, the operation mode of the sensor in the mobile terminal needs to be optimized to prolong the standby time of the mobile terminal.
Specifically, in this step, sensor information corresponding to all sensors in the active state in the mobile terminal needs to be acquired. It is understood that the sensor information at least includes the type of the sensor, the unit power consumption of the sensor, and the corresponding number of each type of sensor.
And S105, calculating the energy-saving association degree between each sensor and the cruising demand grade according to the unit power consumption of the sensor, and judging whether the energy-saving association degree is greater than the preset association degree.
In step S105, the formula for calculating the energy saving association degree is:
wherein the content of the first and second substances,
is shown as
Of the first type
Individual sensor and endurance requirement level
The degree of the energy-saving association between the two,
the degree of association of the reference is represented,
indicates a cruising demand level of the firstkThe number of stages is such that,
，ka serial number representing the level of endurance requirement,mrepresents the maximum level of the endurance requirement level,
is shown as
Of the first type
The sensor unit power consumption of each sensor,
indicates a cruising demand level of the firstkThe level corresponds to the standard power consumption of a single sensor.
It can be understood that, as can be seen from the formula in step S105, in the above formula of the energy saving association degree, the value of the energy saving association degree is directly related to the unit power consumption of the sensor. To a certain extent, it can be understood that, generally, the higher the unit power consumption of the sensor is, the higher the corresponding energy saving association degree is, and the priority for turning off the sensor is higher. I.e. the power consumption loss of the mobile terminal will be reduced even more significantly if it is switched off.
And S106, if yes, controlling the corresponding sensor to be closed.
It can be understood that the corresponding energy saving association degree is calculated by the formula related to the energy saving association degree in the above step S105, and then compared with the preset association degree. In this step, if the energy saving association degree is greater than the preset association degree, the corresponding sensor may be controlled to be turned off.
The invention provides a control method of a sensor, which comprises the steps of firstly, obtaining the corresponding current endurance time of a mobile terminal in the current state, and obtaining the predicted time point of the mobile terminal at the next charging moment; then judging whether the predicted time point of the next charging moment of the mobile terminal is within the interval range corresponding to the current endurance time; if not, calculating to obtain a difference value of the endurance time according to the predicted time point of the next charging moment of the mobile terminal and the terminal value of the current endurance time, and searching and determining to obtain a corresponding endurance requirement grade in a preset mapping table according to the difference value of the endurance time; acquiring sensor information corresponding to all sensors in an activated state in a mobile terminal;
calculating the energy-saving association degree between each sensor and the cruising demand grade according to the unit power consumption of the sensors, and judging whether the energy-saving association degree is greater than the preset association degree; and if so, controlling the corresponding sensor to be closed. The invention can effectively reduce the power consumption of the sensor in an unnecessary state, prolong the service time and ensure the use requirement of an outdoor mode.
Example two:
in order to more clearly and completely illustrate the shutdown control flow of the sensor, referring to fig. 2, a second embodiment of the present invention provides a method for controlling a sensor, the method including the steps of:
s201, after controlling the corresponding sensors to be closed, recording the types and the number of all the sensors switched from the working state to the closed state in the mobile terminal.
S202, calculating to obtain the delay time according to the unit power consumption of the sensor corresponding to each sensor switched from the working state to the closing state, the number of each type of sensor and the residual total electric energy of the mobile terminal.
In this step, the calculation formula of the delay time length is expressed as:
wherein the content of the first and second substances,
the duration of the delay time is represented,
indicating correctionThe coefficients of which are such that,
represents the remaining total power of the mobile terminal,
is shown as
The number of types of sensors that can be used,
，
，
a maximum value of the number of types of sensors is indicated,
representing a maximum corresponding number of sensors of a single type.
And S203, updating the current endurance time according to the delay time length to obtain the updated current endurance time.
Specifically, the updated current endurance time is represented as:
wherein the content of the first and second substances,
indicating the updated current time of flight,
representing the current endurance time.
And S204, judging whether the predicted time point of the next charging time of the mobile terminal is within the interval range corresponding to the updated current endurance time.
It will be appreciated that this step is performed to verify that the duration of the mobile terminal after the current turning off of the partial sensor is supported to the expected point in time of the next charging moment to ensure proper use of the base communication of the mobile terminal throughout the outdoor activity.
And S205, if not, adjusting the preset association degree downwards according to a set step length.
Further, if the predicted time point of the next charging time of the mobile terminal is not within the interval range corresponding to the updated current endurance, it indicates that the endurance of the mobile terminal still cannot be supported to the predicted time point of the next charging time after the partial sensor is turned off currently. Based on this, the preset degree of association needs to be adjusted. Specifically, the threshold is adjusted downward, so that the threshold is lowered, and more qualified sensors are controlled to be turned off, so that the service time is prolonged better.
In this embodiment, the method further includes the steps of:
and S2051, when the preset association degree is reduced to the minimum association degree, judging whether the predicted time point of the next charging moment of the mobile terminal is within the interval range corresponding to the updated current endurance time.
It should be noted that, in this embodiment, if the preset correlation degree is decreased to the minimum correlation degree, all the sensors that meet the shutdown condition are already shutdown. Further, at this time, whether the predicted time point of the next charging time of the mobile terminal is within the interval range corresponding to the updated current endurance time is continuously judged.
And S2052, if not, acquiring the information of all the components, except the sensor, of the mobile terminal in the working state in the current state.
The information of the components at least comprises component types and unit power consumption of the components.
It can be understood that, as described above, under the condition that all the sensors meeting the shutdown condition are shut down, if the endurance time of the mobile terminal still cannot be supported to the expected time point of the next charging time, it is necessary to continue shutting down other types of components (such as a display screen) for endurance operation.
And S2053, determining the unit power consumption of the components corresponding to each type of component from each component type, and sequencing the components according to the descending order of the unit power consumption of the components to obtain a component power consumption sequence table.
In this embodiment, the unit power consumptions corresponding to the components are also sorted to determine the corresponding closing sequence.
And S2054, judging whether each component in the component power consumption sequence table can be closed in the current state of the mobile terminal.
And S2055, if yes, closing the components of the corresponding types according to the power consumption sequence in the component power consumption sequence table.
It can be understood that, in this embodiment, in a state where all the sensors meeting the shutdown condition are shut down, other components meeting the shutdown condition may be searched for and determined and shut down in response to control, so as to better reduce power consumption and prolong the standby time.
Example three:
in practical applications, since two different types of sensors may have the same energy-saving correlation, it is impossible to determine and control which type of sensor needs to be turned off preferentially. Referring to fig. 3, a third embodiment of the present invention provides a method for controlling a sensor, including the following steps:
and S301, when the energy-saving association degrees between the two sensors of different types and the cruising demand grade are equal, respectively obtaining the mode association degrees between the two sensors and the current mode of the mobile terminal.
For example, if the energy saving association degrees of one of the infrared sensors and one of the magnetic field sensors in the mobile terminal are calculated to be equal, the mode association degrees corresponding to the infrared sensors and the magnetic field sensors are continuously and respectively obtained at this time. And the mode association degree is the correlation between the sensor type and the current mode of the mobile terminal. For example, the mode association degree set between the infrared sensor and the current egress mode is 0.75, and the mode association degree set between the magnetic field sensor and the current egress mode is 0.5.
S302, comparing the mode association degrees corresponding to the two sensors, and preferentially closing the sensor with the larger mode association degree.
As described above, the mode association degree set between the infrared ray sensor and the current egress mode is 0.75, and the mode association degree set between the magnetic field sensor and the current egress mode is 0.5. Here, the infrared sensor is preferably turned off.
And S303, calculating to obtain the delay time according to the unit power consumption of the sensor corresponding to each sensor switched from the working state to the closing state, the number of each type of sensor and the residual total electric energy of the mobile terminal.
The detailed implementation of this step has already been described in detail in the first embodiment, and is not described herein again.
And S304, updating the current endurance time according to the delay time length to obtain the updated current endurance time.
And S305, judging whether the predicted time point of the next charging time of the mobile terminal is within the interval range corresponding to the updated current endurance.
And S306, if not, continuing to close the sensor with the smaller mode association degree.
It can be understood that after the sensor with the larger mode relevance is preferentially turned off, the endurance time of the mobile terminal still cannot support the expected time point of the next charging time, and at this time, the sensor with the smaller mode relevance needs to be turned off continuously, so as to further prolong the endurance time of the mobile terminal, and further meet the long-time endurance requirement of the mobile terminal in the outdoor mode.
Example four:
the mobile terminal repeats the above determination and calculation process each time the user is in the outgoing mode. In order to simplify the whole process, referring to fig. 4, a fourth embodiment of the present invention provides a method for controlling sensors, wherein each sensor corresponds to a sensor number, the method further includes the following steps:
s401, when any sensor in the mobile terminal is switched from a working state to a closed state, corresponding sensor closing time and a corresponding sensor number are recorded in real time.
It can be understood that when any sensor in the mobile terminal is switched from the working state to the off state, the corresponding sensor off time is recorded immediately. It should be noted that the sensor off time refers to a time point.
S402, when the estimated time point of the next charging moment of the mobile terminal is judged to be in the interval range corresponding to the updated current endurance time, counting the sensor closing time and the sensor number corresponding to all closed sensors, and generating a sensor control information table according to the sensor closing time and the sensor number, wherein each sensor control information table corresponds to a endurance requirement grade.
It can be understood that, for all sensors switched from the operating state to the off state, the corresponding sensor off time and the sensor number are recorded respectively. Therefore, the sensor control information table can be automatically generated according to the sensor off time and the sensor number.

when the preset association degree is reduced to the minimum value of the association degree, judging whether the predicted time point of the next charging moment of the mobile terminal is within the interval range corresponding to the updated current endurance time;
if not, acquiring a sensor number corresponding to a sensor in a working state in the mobile terminal;
the sensors corresponding to the sensor numbers are marked as white lists.
