According to the technical scheme, the USB detection device is arranged on the side wall of the
Referring to fig. 5, fig. 5 is a flowchart of a calibration method according to an embodiment of the present application, and as shown in fig. 5, the calibration method includes the following steps:
It should be noted that the calibration method provided in the embodiment of the present application is applied to the electronic device in the embodiments described in fig. 1 to fig. 4, that is, a USB detection device is disposed in a Universal Serial Bus (USB) jack of the electronic device, and whether a USB plug is inserted into the USB jack is detected by the USB detection device, where the structure and the working principle of the USB detection device may refer to the description in the embodiments described in fig. 1 to fig. 4, and this embodiment is not described again.
It can be understood that the USB plug is usually a metal conductive object, which may interfere with the detection of the Specific Absorption Rate (SAR) sensor, and affect the detection result of the capacitive sensor. In the embodiment of the application, when the electronic device detects that the USB plug is inserted into the USB jack, the capacitive sensor is controlled to perform first calibration operation, so that parasitic capacitance caused by USB insertion is reduced to zero, interference on the capacitive sensor due to USB plug insertion is avoided, and accuracy of SAR detection results is ensured.
Further, after controlling the capacitive sensor to perform a first calibration operation, the electronic device determines whether the USB plug is in a power-on state. It can be understood that the USB plug is not necessarily in the power-on state after being inserted into the USB jack, and the USB plug is in the power-on state only when the USB is connected to the charging power source or other power supply device.
And 503, controlling the capacitance sensor to perform a second calibration operation when the USB plug is in a power-on state.
It can be understood that, if the USB plug is in the power-on state, there will be current input or output on the pin of the USB plug, and the change of the current will also cause the change of the parasitic capacitance, which affects the detection result of the capacitance sensor. In the embodiment of the application, if the USB plug is detected to be in the power-on state, the capacitive sensor is controlled to perform the second calibration operation, so that the parasitic capacitance caused by the current change is reduced to zero, the interference to the capacitive sensor due to the power-on of the USB plug is avoided, and the accuracy of the SAR detection result is ensured.
It should be noted that, the electronic device may detect whether the USB plug is in the power-on state by detecting a voltage on the VBUS (a power-connected pin of the USB pin and a path thereof), and the specific detection principle may refer to related technologies, which is not described in detail in this embodiment. In addition, the specific implementation process of the capacitive sensor to perform the first calibration operation and the second calibration operation may also refer to the related art.
Optionally, after the
detecting SAR when the USB plug is not in a power-on state.
It will be appreciated that the USB plug may not be powered after it is inserted into the USB jack, for example, the USB plug is not connected to a charging source or other power supply.
In this embodiment, after the electronic device detects that the USB plug is inserted into the USB jack and controls the capacitive sensor to perform the first calibration operation, if it is detected that the USB plug is not in the power-on state, the electronic device directly detects the SAR. Therefore, the electronic equipment carries out the first calibration operation before SAR detection, so that detection errors caused by insertion of a USB plug can be avoided, and the accuracy of SAR detection results is ensured.
Further, after the
detecting SAR in a case where the second calibration operation is completed.
Understandably, after the electronic device completes the second calibration operation, the parasitic capacitance caused by the change of the USB charging current is reduced to zero, the SAR detection is not affected, the SAR is directly detected, and the accuracy of the SAR detection result is guaranteed.
According to the technical scheme provided by the embodiment of the application, under the condition that the electronic equipment detects that the USB plug is inserted into the USB jack, the electronic equipment controls the capacitance sensor to carry out first calibration operation and judges whether the USB plug is in a power-on state or not; and controlling the capacitive sensor to perform a second calibration operation when the USB plug is in a power-on state. Therefore, as long as the electronic equipment detects that the USB plug is inserted into the USB jack, the calibration of the capacitance sensor can be realized no matter whether the USB plug is in a charging state or not, and then the parasitic capacitance caused by the insertion of the USB plug is reduced to zero, so that the accuracy of the SAR detection result is improved.
It should be noted that, in the calibration method provided in the embodiment of the present application, the execution subject may be a calibration device, or a control module in the calibration device for executing the calibration method. In the embodiment of the present application, a calibration method executed by a calibration apparatus is taken as an example to describe the calibration apparatus provided in the embodiment of the present application.
