Figure 1 In the above embodiment, the touch panel 131 and the display panel 141 are implemented as two independent components to perform input and output functions of the wearable device 100, but in some embodiments, the touch panel 131 and the display panel 141 can be integrated to perform the input and output functions of the wearable device 100.

[0056] In addition, the wearable device 100 can further include at least one sensor 150, such as a posture sensor, a distance sensor, a light sensor, and other sensors.

[0057] Specifically, the posture sensor can also be referred to as a motion sensor, and as one type of the motion sensor, an angular velocity sensor (also referred to as a gyroscope) can be listed, which, when configured in the wearable device 100, is used to measure the angular velocity of the wearable device 100 when it is deflected or tilted in a motion state, so that the gyroscope can accurately analyze and determine the actual motion of a user using the wearable device 100, and then perform corresponding operations on the wearable device 100.

Although Figure 1 The WiFi module 170 is shown, but it can be understood that it does not belong to the essential components of the wearable device 100, and can be omitted as needed without changing the essence of the application.

[0063] The processor 180 is the control center of the wearable device 100, which connects all parts of the wearable device 100 via various interfaces and lines, executes various functions of the wearable device 100 and processes data by running or executing software programs and / or modules stored in the memory 120 and calling data stored in the memory 120, and thus monitors the wearable device 100 as a whole. Optionally, the processor 180 can include one or more processing units. Preferably, the processor 180 can integrate an application processor and a modem processor, wherein the application processor mainly processes the operating system, the user interface, and the application program, and the modem processor mainly processes wireless communication.

[0064] It can be understood that the above-mentioned modem processor can also not be integrated into the processor 180.

[0065] The wearable device 100 can further include at least one motor 190. Since the wearable device 100 is a power-consuming device, the motor 190 can be a small motor. Meanwhile, multiple motors can be configured for the wearable device 100 according to the power provided by the motor.

[0066] The wearable device 100 further includes a power supply (not shown in the figure) for supplying power to each component.

[0067] Preferably, the power supply can be logically connected with the processor 180 through a power management system, so that the power management system can realize the functions of managing charging, discharging and power consumption management. Although not shown, the wearable device 100 can also include a Bluetooth module and the like, which will not be described here.

[0068] It should be noted that the above Figure 1 The structure shown is only an example, and the embodiments of the present application are not limited thereto.

[0069] Figure 2 An exemplary flow of the battery detection of the wearable device provided by the embodiments of the present application is shown, which can be executed by the device for battery detection of the wearable device. As shown in Figure 2 The flow specifically includes:

[0070] In step 201, the battery detection circuit of the wearable device is controlled to collect the mainboard NTC sampling and the current ADC sampling.

[0071] In the embodiments of the present application, the battery detection circuit includes a first resistor R1, a second resistor R2, a third resistor R3, a first protection diode VD1 and a jumper point AG. The battery includes a first pin 3011, a second pin 3012 and a third pin 3013.

[0072] The first pin 3011 of the battery is connected to the mainboard power supply pin of the wearable device, the second pin 3012 of the battery is connected to the first end 3021 of the first resistor R1, and the second end 3022 of the first resistor R1 is connected to the ADC pin of the NTC of the mainboard. The first end 3031 of the second resistor R2 is connected to the ground pin of the mainboard, and the second end 3032 of the second resistor R2 is connected to the second end 3022 of the first resistor R1. The first end 3051 of the first protection diode VD1 is connected to the ground pin of the mainboard, and the second end 3052 of the first protection diode VD1 is connected to the first end 3021 of the first resistor R1. 3021 .

[0073] The third pin 3013 of the battery is connected to the first end 3091 of the jumper point AG, the second end 3092 of the jumper point AG is connected to the current sampling ADC pin of the mainboard, the first end 3041 of the third resistor R3 is connected to the ground pin of the mainboard, and the second end 3042 of the third resistor R3 is connected to the first end 3091 of the jumper point AG.

[0074] The battery detection circuit further comprises a first capacitor C1, a second capacitor C2 and a second protection diode VD2. The first end 3061 of the first capacitor C1 is connected to the first pin 3011 of the battery, and the second end 3062 of the first capacitor C1 is connected to the ground pin of the mainboard. The first end 3071 of the second capacitor C2 is connected to the first pin 3011 of the battery, and the second end 3072 of the second capacitor C2 is connected to the ground pin of the mainboard. The first end 3081 of the second protection diode VD2 is connected to the first pin 3011 of the battery, and the second end 3082 of the second protection diode VD2 is connected to the ground pin of the mainboard.

[0075] After the battery detection circuit is connected to the ADC pin of the NTC of the mainboard, the mainboard NTC sampling can be realized, and after the battery detection circuit is connected to the current sampling ADC pin of the mainboard, the current ADC sampling can be realized. In the battery, the NTC resistor is connected between the second pin 3012 and the third pin 3013 of the battery. In step 202, the voltage of the NTC resistor is determined according to the mainboard NTC sampling and the current ADC sampling.

[0076] Specifically, the difference between the mainboard NTC sampling and the current ADC sampling can be determined as the voltage of the NTC resistor.

[0077] In step 203, the resistance value of the NTC resistor of the battery of the wearable device is determined according to the voltage of the NTC resistor.

[0078] According to the voltage of the NTC resistor, the resistance value of the NTC resistor of the battery of the wearable device is obtained. Compared with the prior art, when the current is too large, the voltage value of the current detection resistor is large and changes in real time, and when the NTC resistance value is small in a low-temperature environment, the voltage across the NTC resistor is greatly affected by the voltage of the current detection resistor, and the calculated NTC resistance value is easily deviated from the actual component. The resistance value of the NTC resistor obtained by the embodiment of the present application is more accurate.

[0079] Specifically, the resistance value of the NTC resistor of the battery can be obtained by subtracting the resistance value of the first resistor R1 from the ratio of the voltage of the NTC resistor to the mainboard NTC sampling current. The mainboard NTC sampling current can also be referred to as the NTC sampling current of the NTC sampling chip or the power management chip.

[0080] The above embodiment shows that the battery detection circuit of the wearable device collects the mainboard NTC sampling and the current ADC sampling, determines the voltage of the NTC resistor according to the mainboard NTC sampling and the current ADC sampling, and determines the resistance value of the mainboard NTC resistor according to the voltage of the NTC resistor. By comparing the mainboard NTC sampling and the current ADC sampling, the problem of deviation in calculating the NTC resistance value caused by the voltage of the NTC resistor being affected by the voltage of the current detection can be prevented, and the wiring space of the mainboard can be saved, and the volume of the wearable device can be reduced.
