The embodiments of the present invention will be described in detail below with reference to the accompanying drawings,

and the central processing unit of S22 also receives the signal and adjusts the screen brightness of the electronic equipment.
In this embodiment, the provided information processing method may utilize a distance sensor that is provided in the electronic device itself to test a first distance between a target object and the electronic device, where the target object may be, for example, a person, and more specifically, may be or may not be an owner of the electronic device; after sensing the first distance, the distance sensor sends a signal based on the first distance, the distance sensor has the original function in the electronic equipment that the signal sent based on the first distance is received by a central processing unit, and the central processing unit adjusts the brightness of a screen based on the received signal; for example, when the distance sensor senses that a first distance between a target object and the electronic equipment is short, a first signal is sent out, and after the central processing unit receives the first signal, the screen brightness of the electronic equipment is adjusted to be 0, namely the electronic equipment is controlled to turn off the screen, so that the energy consumption of the electronic equipment is reduced, and the purpose of saving electricity is achieved; when the distance sensor senses that the first distance between the target object and the electronic equipment is far, a second signal is sent out, and after the central processing unit receives the second signal, the screen brightness of the electronic equipment is adjusted to be normal brightness so as to facilitate normal use and watching of a user.
In the application, in order to achieve the purpose that when a human body contacts the electronic device in a close range, the electronic device performs corresponding power adjustment, so as to reduce the radiation influence of the electronic device on the human body, the radio frequency module also receives a signal sent by the distance sensor, and finally, the radio frequency module adjusts the power of the electronic device based on the received signal. For example, when the distance sensor senses that the first distance between the target object and the electronic device is short, a first signal is sent out, and after the radio frequency module receives the first signal, the power of the electronic device can be reduced, so that the influence of radiation of the electronic device on a human body is reduced; when the distance sensor senses that the first distance between the target object and the electronic equipment is far, the second signal is sent out, and after the radio frequency module receives the second signal, the power of the electronic equipment can be adjusted to reach the power value of normal work, so that the electronic equipment can normally work when the distance from the electronic equipment to a human body is far and radiation influence on the human body cannot be caused.

For example, specifically, when the distance sensor senses that a first distance between the target object and the electronic device is short, a first signal is sent out, the processor receives and processes the first signal, then the processor sends the processed first signal to the radio frequency module, and after the radio frequency module receives the processed first signal, the power of the electronic device is reduced, so that the influence of radiation of the electronic device on a human body is reduced; when the distance sensor senses that a first distance between a target object and the electronic equipment is far, a second signal is sent out, the processor receives the second signal and processes the second signal, then the processor sends the processed second signal to the radio frequency module, and the radio frequency module receives the processed second signal and then adjusts the power of the electronic equipment to reach the power value of normal work, so that the electronic equipment can normally work when the distance sensor senses that the distance between the electronic equipment and the electronic equipment is far from a human body and radiation influence cannot be caused on the human body.

Hereinafter, for convenience of description, the preset distance is taken as a specific numerical value for illustration, but the preset distance is not limited to any one. The preset distance is a safety distance threshold between the electronic equipment and the human body, and when the distance between the human body and the electronic equipment is smaller than the preset distance, the radiation of the electronic equipment will threaten the health of the human body, so that the power of the electronic equipment needs to be reduced to ensure that the radiation does not influence the health of the human body; when the distance between the human body and the electronic equipment is larger than the preset distance, the radiation of the electronic equipment cannot influence the health of the human body, so that the power of the electronic equipment does not need to be adjusted, and the electronic equipment can be in a normal working power range.
In one embodiment, when the distance sensor senses a first distance between the target object and the electronic device, the first distance is compared with a preset distance to obtain a comparison result, and then a signal is sent based on the comparison result. Specifically, when the distance sensor judges that the first distance is smaller than the preset distance, a first signal is sent; and when the distance sensor judges that the first distance is greater than the preset distance, sending a second signal.
In other embodiments provided by the present invention, the sending a signal, including,
when the first distance is smaller than the preset distance, sending a first signal;
the radio frequency module receives the signal and adjusts power of the electronic device, including,
the radio frequency module receives the first signal and adjusts the power value of the electronic equipment to a first power range, wherein the power value in the first power range is a safe power value corresponding to a human body.
In this embodiment, after the distance sensor senses a first distance between the target object and the electronic device, the first distance is compared with a preset distance, and when the comparison result shows that the first distance is smaller than the preset distance, a first signal is sent; the radio frequency module receives the first signal and adjusts a power value of the electronic device to a first power range based on the first signal, wherein the power value in the first power range is a safe power value corresponding to a human body, that is, based on the first signal, under the condition that the human body contacts the electronic device in a close range, the power of the electronic device is reduced, so that radiation does not affect human health.
In another embodiment of the present invention, the sending a signal based on the comparison result includes,
when the first distance is greater than the preset distance, sending a second signal;
the radio frequency module receives the signal and adjusts power of the electronic device, including,
and the radio frequency module receives the second signal and adjusts the power value of the electronic equipment to a second power range, wherein the power value in the second power range is the power value enabling the electronic equipment to normally work.
In this embodiment, after sensing a first distance between the target object and the electronic device, the distance sensor compares the first distance with a preset distance, and sends a second signal when the comparison result shows that the first distance is greater than the preset distance; the radio frequency module receives the second signal and adjusts the power value of the electronic device to a second power range based on the second signal, wherein the power value in the second power range is a power value enabling the electronic device to normally work, that is, based on the second signal, under the condition that a human body is far away from the electronic device and does not pose a health threat to the human body, the power of the electronic device is adjusted to the power value enabling the electronic device to normally work.
As shown in fig. 3, in an embodiment provided by the present invention, the method further includes, S31, after the rf module adjusts the power of the electronic device based on the signal, sending a third signal to the distance sensor, where the third signal indicates that the rf module has performed the power adjustment of the electronic device;
the distance sensor stops working.
In this embodiment, when the radio frequency module has adjusted the power of the electronic device based on the signal, for example, adjusting the power of the electronic device includes adjusting the power of the electronic device from a power value in the second power range to a power value in the first power range, and adjusting the power of the electronic device from the power value in the first power range to a power value in the second power range. The present invention is not limited to this, and the distance sensor stops working after receiving the third signal, as long as the radio frequency module adjusts the power of the electronic device based on the signal and sends the third signal to the distance sensor. The stop operation is only of a pause nature, energy consumption can be saved and the processing speed of the processor can be improved by pausing the operation of the distance sensor, but after the preset time, the distance sensor automatically starts to operate, namely, the first distance between the target object and the electronic equipment is continuously sensed.
For example, in one embodiment, when the user answers the phone call, the distance sensor senses a first distance between the target object and the electronic device, compares the first distance with a preset distance, and sends a first signal when the comparison result shows that the first distance is smaller than the preset distance; the radio frequency module receives the first signal, adjusts the power value of the electronic equipment to be within a first power range based on the first signal, namely, the radio frequency module adjusts the power value of the electronic equipment from the power value of normal operation to the power value within the first power range which enables human bodies to be safe, after the power of the electronic equipment is adjusted, a third signal is sent to the distance sensor, after the distance sensor receives the third signal, the operation is suspended so as to reduce the energy consumption of the electronic equipment, and after a preset time, the distance sensor starts to operate again. In this embodiment, it takes a period of time for the user to answer the call, and the distance between the human body and the electronic device is always smaller than the preset distance in this period of time, so that the distance sensor does not need to specifically sense the distance between the human body and the electronic device in a period of time, and the operation of the distance sensor can be suspended, so as to save energy consumption for the electronic device.
As shown in fig. 4, in another embodiment provided by the present invention, the method further includes, after the distance sensor sends a signal, S32, the distance sensor detects whether a third signal is sent out by the radio frequency module at a certain time interval, and when the third signal is detected, the distance sensor stops working;
wherein the third signal is indicative of the radio frequency module having performed a power adjustment of the electronic device.
In this embodiment, after the distance sensor sends a signal to the radio frequency module, more specifically, after the distance sensor sends a signal to the radio frequency module through a processor in the electronic device, the radio frequency module adjusts the power of the electronic device based on the signal. When the radio frequency module adjusts the power of the electronic equipment based on the signal, a third signal is sent; the distance sensor detects whether a third signal is sent out by the radio frequency module at a certain time interval, and when the third signal is detected, the distance sensor stops working. The stop operation is only of a pause nature, energy consumption can be saved and the processing speed of the processor can be improved by pausing the operation of the distance sensor, but after the preset time, the distance sensor automatically starts to operate, namely, the first distance between the target object and the electronic equipment is continuously sensed.
For example, in one embodiment, when the user answers the phone call, the distance sensor senses a first distance between the target object and the electronic device, compares the first distance with a preset distance, and sends a first signal when the comparison result shows that the first distance is smaller than the preset distance; the radio frequency module receives the first signal, adjusts the power value of the electronic equipment to be within a first power range based on the first signal, namely, the radio frequency module adjusts the power value of the electronic equipment to be within the first power range which enables a human body to be safe from the power value of normal work, after the power of the electronic equipment is adjusted, the radio frequency module sends a third signal, the distance sensor detects whether the radio frequency module sends the third signal at a certain time interval, when the third signal is detected, the radio frequency module stops working to reduce the energy consumption of the electronic equipment, and after a preset time, the distance sensor restarts working. In this embodiment, it takes a period of time for the user to answer the call, and the distance between the human body and the electronic device is always smaller than the preset distance in this period of time, so that the distance sensor does not need to specifically sense the distance between the human body and the electronic device in a period of time, and the operation of the distance sensor can be suspended, so as to save energy consumption for the electronic device.
As shown in fig. 5, a second embodiment of the present invention provides an information processing method applied to an electronic device, where the electronic device includes a distance sensor, a radio frequency module and a central processing unit, the method includes,
s4, the radio frequency module detects signals sent by the distance sensor at certain time intervals;
s5, when detecting that the signal sent by the distance sensor changes, adjusting the power of the electronic equipment;
wherein the signal emitted by the distance sensor is adjusted based on a first distance between the target object and the electronic device; the central processing unit detects signals sent by the distance sensor at certain time intervals, and adjusts the screen brightness of the electronic equipment when the signals sent by the distance sensor are detected to be changed.
In this embodiment, the signal sent by the distance sensor is adjusted based on a first distance between the target object and the electronic device, for example, when the distance sensor senses that the first distance between the target object and the electronic device is short, the first signal is sent; and when the distance sensor senses that the first distance between the target object and the electronic equipment is longer, sending out a second signal. The radio frequency module detects signals sent by the distance sensor at certain time intervals, and when the signals sent by the distance sensor are detected to be changed, the power of the electronic equipment is adjusted. In a specific embodiment, when the radio frequency module detects that the signal sent by the distance sensor is the first signal at a first time and detects that the signal sent by the distance sensor is the first signal at a second time after the first time, the power of the electronic device is not adjusted, so that the electronic device is maintained in a current power state; when the radio frequency module detects that the signal sent by the distance sensor is a first signal at a first moment and detects that the signal sent by the distance sensor is a second signal at a second moment after the first moment, adjusting the power of the electronic equipment to enable the power of the electronic equipment to be adjusted to correspond to the second signal, for example, enabling the power of the electronic equipment to be adjusted to enable the electronic equipment to normally work; when the radio frequency module detects that the signal sent by the distance sensor is the second signal at the first moment and monitors that the signal sent by the distance sensor is the first signal at the second moment after the first moment, the power of the electronic equipment is adjusted to correspond to the first signal, for example, the power of the electronic equipment is adjusted to be the power which can not influence the health of a human body. That is, the rf module will only adjust the power of the electronic device when detecting that the signal sent by the distance sensor changes.
In another embodiment, the central processing unit detects signals sent by the distance sensor at certain time intervals, and adjusts the screen brightness of the electronic device when the signals sent by the distance sensor are detected to be changed. In a specific embodiment, when the central processing unit detects that the signal sent by the distance sensor is the first signal at a first moment and detects that the signal sent by the distance sensor is the first signal at a second moment after the first moment, the screen brightness of the electronic equipment is not adjusted, so that the electronic equipment is maintained in the current screen brightness state; when the central processing unit detects that the signal sent by the distance sensor is a first signal at a first moment and detects that the signal sent by the distance sensor is a second signal at a second moment after the first moment, the screen brightness of the electronic equipment is adjusted to correspond to the second signal, for example, the screen brightness of the electronic equipment is adjusted to the screen brightness enabling the electronic equipment to normally work; when the central processing unit detects that the signal sent by the distance sensor is the second signal at the first moment and monitors that the signal sent by the distance sensor is the first signal at the second moment after the first moment, the screen brightness of the electronic equipment is adjusted to correspond to the first signal, for example, the screen brightness of the electronic equipment is adjusted to be 0, so that the energy consumption of the electronic equipment is reduced, and the purpose of saving electricity is achieved. That is to say, the central processing unit will correspondingly adjust the screen brightness of the electronic device only when detecting that the signal sent by the distance sensor changes.
In another embodiment of the present invention, the adjusting the power of the electronic device when the change of the signal emitted by the distance sensor is detected comprises,
when the signal sent by the distance sensor is detected to be changed from a first signal to a second signal, adjusting the power value of the electronic equipment to be within a second power range, wherein the power value within the second power range is the power value enabling the electronic equipment to normally work;

In another embodiment, when the radio frequency module detects that the signal sent by the distance sensor is the second signal at the first time, and detects that the signal sent by the distance sensor is the first signal at the second time after the first time, that is, when it is detected that the signal sent by the distance sensor is changed from the second signal to the first signal (that is, when the electronic device is far away from the human body, the distance sensor is close to the human body), the power of the electronic device is adjusted to correspond to the first signal, that is, the power value of the electronic device is adjusted within the first power range, so that the radiation of the electronic device does not affect the health of the human body.
