< method examples >

One embodiment of the present disclosure provides a control method of an electronic device, which may be implemented by, for example, an electronic device 1000 as shown in fig. 1. The control method may also be implemented by, for example, the electronic device described in any of the device embodiments above.

In this embodiment, when the change-over switch is switched to the first path, the voltage signal output by the electrode may be obtained by the sampling circuit, and it is determined whether the electronic device is in the water inlet state according to the voltage signal. The following describes a control process of an electronic device in various embodiments.

Taking the electronic device described in the second embodiment of the device as an example, as shown in fig. 9, the method for controlling an electronic device according to this embodiment may include the following steps S1100 to S1300.

Step S1100, acquiring a first voltage signal between the first electrode and the second electrode acquired by the sampling circuit.

The first electrode may be, for example, a LA electrode and the second electrode may be, for example, a RA electrode.

In one embodiment, the first voltage signal between the first electrode and the second electrode can be collected at a preset first time interval, and the power consumption of the electronic device can be reduced.

As shown in fig. 5, in this embodiment, the sampling circuit 104 includes a first resistor R1 and a second resistor R2 connected in series. When the electronic device is not in the water inlet state, that is, thefirst electrode 1011 and thesecond electrode 1012 are not turned on, at this time, the voltage output by the sampling circuit to the main control chip is the voltage across the first resistor R1, that is, V_{Output of}＝V_{Input device}(R1/(R1+ R2)), wherein V_{Input device}For power management module transmissionInto the voltage of the sampling circuit 104. When the electronic device is in a water-entering state, thefirst electrode 1011 and thesecond electrode 1012 are conducted by water, that is, a seventh resistor R7 exists between thefirst electrode 1011 and thesecond electrode 1012, and at this time, the voltage output by the sampling circuit to the main control chip is the resistance at two ends of the first resistor R1 and the seventh resistor R7 after being connected in parallel, that is, V_{Output of}’＝V_{Input device}(R1 '/(R1 ' + R2)), wherein R1 ' ═ R1 × R7/(R1+ R7), V_{Input device}The voltage of the sampling circuit 104 is input to the power management module. Based on this, when the change-over switch 102 is switched to the first path, the main control chip 105 may determine whether the electronic device enters water according to the voltage value of the first voltage signal output by the sampling circuit 102.

Step S1200, comparing the voltage value of the first voltage signal with a preset first threshold.

The first threshold may be set according to the experimental simulation results.

In step S1300, when the voltage value of the first voltage signal is smaller than a preset first threshold, it is determined that the electronic device is in a water inlet state.

When the voltage value of the first voltage signal is smaller than a preset first threshold value, that is, the voltage value V of the first voltage signal_{Output of}V when the electronic device is not in water_{Output of}The difference value of (2) is greater than the safety margin of the voltage change, and at this time, it is determined that the electronic device is in the water inlet state.

After the electronic equipment is determined to be in the water inlet state, the water inlet level of the electronic equipment can be further determined, so that the electronic equipment is controlled to execute corresponding operation according to the water inlet level.

In one embodiment, the control method of the electronic device may further include: steps S2100-S2400.

In step S2100, a pressure signal output by the air pressure sensor is acquired.

In this embodiment, when the electronic device is in the water entry state, the air pressure in the electronic device increases. For example, when the electronic device is dropped into water with a depth of 1 cm, the air pressure inside the electronic device increases by 98 Pa. Based on this, whether the electronic device is in the water inlet state can be determined according to the pressure signal output by the air pressure sensor.

It should be noted that, in this embodiment, the placement position of the air pressure sensor may be set as needed to detect whether the corresponding position of the electronic device is in the water entering state. For example, the air pressure sensor and the second electrode are respectively arranged on the left side and the right side of the electronic device, and water entering on the left side or the right side of the electronic device can be respectively detected.

For example, the pressure signal output by the air pressure sensor may be acquired at a preset second time interval, so that power consumption of the electronic device may be reduced.

In a more specific example, the pressure value of the pressure signal is compared with a preset second threshold value, and when the pressure value of the pressure signal is greater than the preset second threshold value, the electronic equipment is determined to be in the water inlet state.

In a more specific example, in order to improve the detection accuracy, a current pressure signal is acquired, when the pressure value of the current pressure signal is greater than a preset second threshold value, a next pressure signal is acquired, and when the next pressure signal is greater than the preset second threshold value, the electronic device is determined to be in the water inlet state. Thus, the electronic equipment can be prevented from being mistaken for the water entering state due to the air pressure change caused by the change of the motion state of the user.

In step S2200, a capacitance signal output by the touch screen is obtained.

In this embodiment, when the electronic device is in the water-entering state, the capacitance value of the capacitance signal output by the touch screen changes. Based on the water level, the electronic equipment can be determined by combining the electrode and the air pressure sensor.

For example, the capacitance signal output by the touch screen can be acquired at a preset second time interval, so that the power consumption of the electronic device can be reduced.

In a more specific example, the capacitance value of the capacitance signal is compared with a preset third threshold value, and when the capacitance value of the capacitance signal is greater than the preset third threshold value, it is determined that the electronic device is possibly in the water-entering state.

And step S2300, determining the water inlet grade of the electronic equipment according to the first voltage signal, the pressure signal and the capacitance signal.

Because the first electrode, the second electrode, the air pressure sensor and the touch screen are respectively arranged at different positions of the electronic equipment, the water inlet position of the electronic equipment can be determined according to the first voltage signal, the pressure signal and the capacitance signal, and therefore the water inlet grade of the electronic equipment can be determined. For example, the first electrode is located on a bottom shell of the electronic device, the air pressure sensor is arranged close to one side of the electronic device, the touch screen is arranged on the upper surface of the electronic device, and the water inlet position of the electronic device can be determined according to the electrode, the air pressure sensor and the touch screen, so that the water inlet level of the electronic device can be determined. According to the embodiment of the disclosure, the detection accuracy can be improved, the electronic equipment is controlled to execute corresponding operation according to the water inlet level, and the use by a user is facilitated.

In a more specific example, the step of determining the water ingress level of the electronic device based on the first voltage signal, the pressure signal, and the capacitance signal may further comprise: steps S2310-S2340.

In step S2310, a first detection result is determined according to a comparison result of the voltage value of the first voltage signal and the first threshold.

For example, when the voltage value of the first voltage signal is smaller than a preset first threshold, it is determined that the electronic device is in the water inlet state, and the first detection result is "1". When the voltage value of the first voltage signal is greater than or equal to a preset first threshold value, it is determined that the electronic equipment is not in the water inlet state, and the first detection result is '0'.

Step S2320, determining a second detection result according to a comparison result between the pressure value of the pressure signal and a preset second threshold.

For example, when the pressure value of the pressure signal is greater than a preset second threshold value, it is determined that the electronic device is in the water inlet state, and the first detection result is "1". When the pressure value of the pressure signal is smaller than or equal to a preset second threshold value, it is determined that the electronic equipment is not in the water inlet state, and the first detection result is '0'.

In step S2330, a third detection result is determined according to a comparison result between the capacitance value of the capacitance signal and a preset third threshold.

For example, when the capacitance value of the capacitance signal is greater than the preset third threshold value, it is determined that the electronic device is in the water inlet state, and the first detection result is "1". When the capacitance value of the capacitance signal is smaller than or equal to a preset third threshold value, it is determined that the electronic device is not in the water inlet state, and the first detection result is '0'.

That is, the electronic device is in a state where the whole machine is immersed in water, for example, the electronic device falls into water. At this time, the control electronics activate the drainage mechanism to perform a drainage operation, e.g., the main control chip controls the motor to vibrate at different frequencies with a maximum amount of vibration to drain water within the electronics.

According to the embodiment of the disclosure, the detection accuracy can be improved, the electronic equipment is controlled to execute corresponding operation according to the water inlet level, and corresponding treatment can be timely performed when the electronic equipment is in the water inlet state, so that the electronic equipment is prevented from being damaged, and the electronic equipment is convenient for a user to use.
