Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a flowchart of a sensor control method according to an embodiment of the present invention is shown, and is applied to a first electronic device, where the method specifically includes the following steps:
And 102, reducing the specific absorption rate of the electronic equipment and controlling a power supply in the electronic equipment to stop supplying power to a second target sensor in the electronic equipment under the condition that the distance between the electronic equipment and the target object is smaller than or equal to a preset threshold value.
Wherein, under the condition that the first target sensor is an infrared sensor, the second target sensor is a specific absorption rate SAR sensor; or, in the case where the first target sensor is a SAR sensor, the second target sensor is an infrared sensor.
The traditional electronic equipment design is that an SAR sensor and an infrared sensor are stacked and have independent functions. Although the two sensor application scenarios are different, there is a common part of the functionality, namely distance detection. The SAR sensor can detect whether a living object (such as a human body) approaches by changing capacitance on an induction channel of the SAR sensor and converting the change of the capacitance into the change of voltage when the living object approaches the SAR sensor. The infrared sensor judges whether a human body or an object approaches by utilizing the infrared reflection quantity received by the receiving end. When the electronic equipment is in a call scene, the distance detection functions of the SAR sensor and the infrared sensor coexist, so that the power consumption of the system is increased, and the energy waste is caused.
In view of the above technical problems, in the embodiment of the present invention, when an electronic device is in a state of answering a call or dialing a call, it may be determined whether the electronic device is in a communication state, and when the electronic device is in the communication state, a first target sensor in the electronic device detects a distance between the electronic device and a target object, and when the distance is less than or equal to a preset threshold, the specific absorption rate of the electronic device is reduced, and a power supply in the electronic device is controlled to stop supplying power to a second target sensor in the electronic device, and when the first target sensor is an infrared sensor, the second target sensor is an SAR sensor; or, in the case that the first target sensor is an SAR sensor, the second target sensor is an infrared sensor, that is, only one of the infrared sensor and the SAR sensor is used to detect the distance between the electronic device and the target object. And in the case that the distance is detected to be less than or equal to the preset threshold value, reducing the specific absorption rate of the electronic device, and controlling a power supply in the electronic device to stop supplying power to a second target sensor in the electronic device, so that the specific absorption rate of the electronic device is reduced, and the power consumption of the electronic device is reduced. For example, in a case where the first target sensor is an infrared sensor, the infrared sensor detects a distance between the electronic device and a target object (in this case, the SAR sensor does not participate in detecting the distance), and in a case where the distance is less than or equal to a preset threshold, the electronic device performs an operation of reducing the SAR, and controls the power supply to stop supplying power to the SAR sensor in the electronic device, so that the SAR sensor stops operating, thereby saving the electric quantity of the power supply and causing the SAR sensor to consume no electric quantity at this time. In the case where the first target sensor is an infrared sensor, the target object may be a human body or an object.
Or, in the case that the first target sensor is an SAR sensor, the SAR sensor detects a distance between the electronic device and the target object (in this case, the infrared sensor does not participate in detecting the distance), and in the case that the distance is smaller than or equal to a preset threshold, the electronic device performs an operation of reducing the SAR, and controls the power supply to stop supplying power to the infrared sensor in the electronic device, so that the infrared sensor stops working, thereby saving the electric quantity of the power supply. In the case where the first target sensor is an SAR sensor, the target may be a human body.
Therefore, through the steps 101 and 102, when the electronic device is in a communication state, not only the specific absorption rate of the electronic device can be reduced, but also the power consumption of the electronic device can be reduced.
In the sensor control method provided by this embodiment, when the electronic device is in a communication state, the first target sensor in the electronic device detects a distance between the electronic device and the target object, and when the distance between the electronic device and the target object is less than or equal to a preset threshold, the specific absorption rate of the electronic device is reduced, and the power supply in the electronic device is controlled to stop supplying power to the second target sensor in the electronic device. Therefore, when the electronic equipment is in a communication state, the specific absorption rate of the electronic equipment is reduced, and the power consumption of the electronic equipment is reduced, namely the power consumption of the electronic equipment is reduced on the basis of ensuring the reduction of the specific absorption rate.
Referring to fig. 2, a block diagram of an electronic device according to an embodiment of the present invention is shown, a switch is disposed between a power supply and a SAR sensor, in fig. 2, a first target sensor is an infrared sensor, a second target sensor is a system architecture diagram, which is shown by way of example, of the SAR sensor, a processor controls the switch to be opened, so that the power supply stops supplying power to the SAR sensor, and the processor controls the switch to be closed, so that the power supply supplies power to the SAR sensor. It can be understood that the power consumption reduction scheme when the first target sensor is the SAR sensor and the second target sensor is the infrared sensor can be realized only by interchanging the positions of the infrared sensor and the SAR sensor in fig. 2. That is, a switch is arranged between the power supply and the second target sensor, the processor controls the switch to be switched off, so that the power supply stops supplying power to the second target sensor, and the processor controls the switch to be switched on, so that the power supply supplies power to the second target sensor.
Referring to fig. 3, which shows a flow chart of a sensor control method according to another embodiment of the present invention, based on fig. 2, the method provided by the present embodiment includes the following steps:
In the case that the electronic device is in a communication state, executing step 302; in the case that the electronic device is not in the communication state, step 303 is executed, and after step 303 is executed, step 301 may be continuously executed to continuously determine whether the electronic device is in the communication state.
And step 303, controlling the switch to be closed so as to control the power supply to supply power to the second target sensor.
In the switch closed state, the power supply can supply power to the second target sensor (for example, the second target sensor is the SAR sensor), so that the SAR sensor is in a normal working state.
Executing step 305 if the distance between the electronic device and the target object is less than or equal to the preset threshold, that is, if the distance between the electronic device and the target object detected by the infrared sensor is less than or equal to the preset threshold; in the case that the distance between the electronic device and the target object is greater than the preset threshold, step 303 is executed, and step 302 is continuously executed after step 303 is executed, that is, in the communication state, if the detected distance between the electronic device and the target object is greater than the preset threshold, the distance between the electronic device and the target object may be continuously detected by the first target sensor in the electronic device. The distance between the electronic device and the target object can be periodically detected through the first target sensor in the electronic device, or the distance between the electronic device and the target object can be detected in real time through the first target sensor in the electronic device. Under the condition that the distance between the electronic equipment and the target object is periodically detected through the first target sensor in the electronic equipment, the power consumption of the electronic equipment can be further saved.
In this embodiment, the first target sensor is an infrared sensor, and the second target sensor is an SAR sensor, for example, that is, the distance between the electronic device and the target is detected by the infrared sensor, and step 305 is executed when the distance between the electronic device and the target detected by the infrared sensor is smaller than or equal to a preset threshold.
And 305, reducing the specific absorption rate of the electronic equipment, and controlling a switch connected between the power supply and the second target sensor in the electronic equipment to be disconnected so as to control the power supply to stop supplying power to the second target sensor.
After step 305 is performed, step 306 is then performed.
And step 306, judging whether the electronic equipment keeps the communication state.
And executing step 302 under the condition that the electronic equipment keeps a communication state, and after executing step 302 and step 304, if the distance between the electronic equipment and the target object is greater than the preset threshold, executing step 303 to control the switch to be closed so that the power supply starts to supply power to the second target sensor to ensure that the second target sensor works normally. After the step 303 is executed, step 306 is continuously executed to determine whether the electronic device continues to maintain the communication state (i.e., determine whether the electronic device is still in the communication state), so that when the electronic device maintains the communication state, step 302 and step 304 are continuously executed to determine whether the detected distance between the electronic device and the target object is less than or equal to the preset threshold. If the electronic device does not continue to maintain the communication state, the flow ends.
It should be noted that, if step 302 is repeatedly executed after steps 301, 302, 304, 305, and 306, since the switch between the power supply and the second target sensor is turned off, the second target sensor is in a stop state, and the second target sensor does not participate in the distance detection, that is, only the first target sensor performs the distance detection between the electronic device and the target in step 302, it is not necessary to simultaneously detect the distance between the electronic device and the target with both sensors, thereby reducing the power consumption of the electronic device. When step 302 is repeatedly executed, the distance between the electronic device and the target object may be periodically detected by the first target sensor in the electronic device, or the distance between the electronic device and the target object may be detected in real time by the first target sensor in the electronic device. Under the condition that the distance between the electronic equipment and the target object is periodically detected through the first target sensor in the electronic equipment, the power consumption of the electronic equipment can be further saved.
In the embodiment of the invention, under the condition that the first target sensor is an infrared sensor and the second target sensor is an SAR sensor, through the steps 301 to 306, when the distance between the electronic equipment and the target object is smaller than or equal to the preset threshold, SAR can be reduced, and the switch is controlled to be switched off, so that the power supply is controlled to stop supplying power to the SAR sensor, and the power consumption of the electronic equipment is reduced on the basis of reducing the SAR. And under the condition that the distance between the electronic equipment and the target object is larger than a preset threshold value, the SAR sensor can work normally.
It should be noted that, if the power supply in fig. 2 can supply power to the second target sensor as well as other components (for example, a sensor for detecting a fingerprint), the power supply can stop supplying power to the second target sensor by setting a switch between the power supply and the second target sensor, so that on the basis of reducing power consumption, the power supply is not affected to supply power to other components in the electronic device, that is, a path between the power supply and the other components is not cut off, and normal operation of the other components is ensured.
Similar to the above steps 301 to 306, when the first target sensor is an SAR sensor and the second target sensor is an infrared sensor, details are not repeated here, and the power consumption of the electronic device can still be reduced on the basis of reducing the SAR.
Optionally, if the switch shown in fig. 2 is not set, after the controlling the power supply in the electronic device stops supplying power to the second target sensor in the electronic device, the method may further include the following steps:
detecting a distance between the electronic equipment and a target object through a first target sensor in the electronic equipment under the condition that the electronic equipment keeps a communication state;
and controlling the power supply to start supplying power to the second target sensor under the condition that the distance is larger than the preset threshold value.
Referring to fig. 4, a schematic structural diagram of a sensor control apparatus according to an embodiment of the present invention is shown, where the apparatus 400 includes:
a first determining module 410, configured to determine whether a distance between the electronic device and a target object, which is detected by a first target sensor in the electronic device, is smaller than or equal to a preset threshold value when the electronic device is in a communication state;
the control module 420 is configured to, when the distance between the electronic device and the target object is less than or equal to the preset threshold, reduce a specific absorption rate of the electronic device, and control a power supply in the electronic device to stop supplying power to a second target sensor in the electronic device;
wherein, in the case that the first target sensor is an infrared sensor, the second target sensor is a specific absorption rate SAR sensor; or, in the case that the first target sensor is the SAR sensor, the second target sensor is the infrared sensor.
The sensor control apparatus provided in this embodiment detects a distance between the electronic device and the target object through the first target sensor in the electronic device when the electronic device is in a communication state, reduces a specific absorption rate of the electronic device when the distance between the electronic device and the target object is less than or equal to a preset threshold, and controls the power supply in the electronic device to stop supplying power to the second target sensor in the electronic device. Therefore, when the electronic equipment is in a communication state, the specific absorption rate of the electronic equipment is reduced, and the power consumption of the electronic equipment is reduced, namely the power consumption of the electronic equipment is reduced on the basis of ensuring the reduction of the specific absorption rate.
