FIG. 2 is a flowchart of a power saving method in an embodiment. As shown in FIG. 2 , the power saving method includes steps S202 to S206. in:

Step S202, acquiring a device power consumption parameter, which refers to a parameter value reflecting the current power consumption of the device.

In one embodiment, the device power consumption parameter refers to a parameter value reflecting the current power consumption of the device. For example, the device power consumption parameter may be one or both of the current power value of the device and the current processor occupancy rate. Wherein, the device refers to an electronic device installed with a proximity sensor, for example, the device may be a personal computer, a mobile terminal, a personal digital assistant, a wearable electronic device, and the like.

In step S204, it is detected that the power consumption parameter of the device is within the specified parameter range, and then the threshold of the proximity sensor is set as the fixed threshold of the sensor.

In one embodiment, the specified parameter range refers to a preset parameter range of the power consumption parameter of the device, and when the power consumption parameter of the device is within the specified parameter range, the device is considered to be in a state where energy tends to be exhausted. For example, if the power consumption parameter of the device is within the specified parameter range, the current power value of the device is lower than 20%, or the current processor occupancy rate of the device is higher than 80%.

In one embodiment, the device scans the surrounding objects according to a preset period through the proximity sensor, and determines the proximity value between the device and the object, and the proximity value reflects the distance from the object to the device.

In one embodiment, the proximity sensor threshold refers to a threshold for determining the distance of an object, including a proximity threshold and a distance threshold. When the proximity value is less than the distance threshold, it is determined that the device is in a state away from the object; when the proximity value is greater than the proximity threshold, it is determined that the device is in a state of approaching the object.

In one embodiment, the fixed threshold of the sensor refers to a preset fixed threshold of the proximity sensor. When it is detected that the power consumption parameter of the device is within the specified parameter range, the threshold of the proximity sensor is set as the fixed threshold of the sensor. value.

Step S206, stop updating the proximity sensor threshold.

In one embodiment, the device periodically detects the proximity value to the surrounding objects, and dynamically updates the proximity sensor threshold value according to each collected proximity value, and the currently collected proximity value is compared with the last updated proximity sensor threshold value. Compare to judge the far and near state of the current object. When the power consumption parameter of the detection device is within the specified parameter range, it is considered that the device is currently in a state where energy tends to be exhausted, and the dynamic update of the threshold of the proximity sensor is stopped, and the threshold of the proximity sensor is set as the fixed threshold of the sensor.

In the power saving method provided by the embodiment of the present invention, the threshold value of the proximity sensor is set as the fixed threshold value of the sensor, and the threshold value of the proximity sensor is no longer updated, which saves a lot of power consumption when updating the threshold value of the sensor, and greatly reduces the power consumption of the device , saving power.

FIG. 3 is a flowchart of a power saving method in another embodiment. As shown in FIG. 3 , the power saving method includes step S302 to step 310 . in:

In one embodiment, the device power consumption parameter refers to a parameter value reflecting the current power consumption of the device. For example, the device power consumption parameter may be one or both of the current power value of the device and the current processor occupancy rate. Wherein, the device refers to an electronic device installed with a proximity sensor, for example, the device may be a personal computer, a mobile terminal, a personal digital assistant, a wearable electronic device, and the like.

It can be understood that the current power value of the device refers to a value that reflects the current power of the device, and the current processor occupancy rate of the device refers to a value that reflects the resource usage rate of the program currently running on the device in the processor. The lower the current power value and the higher the current processor occupancy rate, the higher the current power consumption of the device.

In one embodiment, the device scans the surrounding objects according to a preset period through the proximity sensor, and determines the proximity value between the device and the object, and the proximity value reflects the distance from the object to the device. The proximity sensor threshold refers to the threshold for judging the distance of an object, including the proximity threshold and the distance threshold. When the proximity value is less than the distance threshold, it is determined that the device is in a state away from the object; when the proximity value is greater than the proximity threshold, it is determined that the device is in a state of approaching the object.

Step S306, determining the dynamic threshold of the sensor according to the proximity value, and obtaining the fixed threshold of the sensor according to the dynamic threshold of the sensor.

In one embodiment, the device periodically detects the proximity value to surrounding objects, and when the detected device power consumption parameter exceeds a specified parameter range, the device is considered to be in a state of sufficient energy. The threshold value of the proximity sensor is dynamically updated according to the proximity value collected each time, the updated threshold value of the proximity sensor is the dynamic threshold value of the sensor, and the dynamic threshold value of the sensor updated each time is recorded. Compare the currently collected proximity value with the last updated sensor dynamic threshold to determine the current state of the object.

In one embodiment, the sensor fixed threshold refers to a preset fixed threshold of the proximity sensor. A specified sensor dynamic threshold is obtained according to the sensor dynamic threshold, and a sensor fixed threshold is obtained according to the specified sensor dynamic threshold and the limit threshold. Wherein, the specified sensor dynamic threshold refers to the pre-specified sensor dynamic threshold in the recorded sensor dynamic threshold updated each time. For example, the specified sensor dynamic threshold may be a maximum sensor dynamic threshold, a minimum sensor dynamic threshold, or an average sensor dynamic threshold. The limit threshold refers to the condition threshold that needs to be satisfied by the limit sensor fixed threshold, for example, the limit sensor fixed threshold cannot be greater than the limit threshold or cannot be smaller than the limit threshold.

In one embodiment, several groups of sensor dynamic thresholds whose difference is less than the preset difference within the preset time period when the device is in the remote state are obtained, and the maximum value is taken from the several groups of sensor dynamic thresholds as the specified Sensor dynamic threshold.

In one embodiment, it is also possible to obtain the minimum sensor dynamic threshold value among the sensor dynamic threshold values, and detect that the maximum sensor dynamic threshold value is greater than the limit threshold value, then use the minimum sensor dynamic threshold value as the sensor fixed threshold value, otherwise set The limiting threshold acts as a sensor fixed threshold.

In step S308, it is detected that the power consumption parameter of the device is within the specified parameter range, and then the threshold of the proximity sensor is set as the fixed threshold of the sensor.

In one embodiment, if the power consumption parameter of the detected device is within a specified parameter range, it is considered that the device is in a state where energy tends to be exhausted. Then set the threshold of the proximity sensor as the fixed threshold of the sensor. The sensor fixed threshold is the sensor fixed threshold acquired in step S306.

Step S310, stop updating the proximity sensor threshold.

In one embodiment, when the power consumption parameter of the device is within the specified parameter range, it is considered that the device is currently in a state where energy tends to be exhausted, and the device stops dynamically updating the threshold of the proximity sensor, and uses a fixed threshold of the sensor. When it is detected again that the power consumption parameter of the device exceeds the specified parameter range, the threshold value of the proximity sensor can be dynamically updated again.

In the power saving method provided by the embodiment of the present invention, when it is detected that the power consumption parameter of the device is within the specified parameter range, it is determined that the device is in a state where the energy tends to be exhausted, and the threshold value of the proximity sensor is set as the fixed threshold value of the sensor, and no longer Update the proximity sensor threshold.
