In addition, the character "/" in this article, unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.

[0064] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0065] See figure 1 The embodiment of the present invention provides a method for voltage detection. The main flow of the method is described as follows.

[0066] S101: When the user's weight changes, determine whether the user's weight change is greater than or equal to a preset threshold;

[0067] In the embodiment of the present invention, the preset threshold may be determined by those skilled in the art based on actual experience, or the preset threshold may also be set by the user, which is not limited in the embodiment of the present invention.

[0068] In the embodiment of the present invention, the weight obtained by the user's current measurement can be compared with the weight obtained by the user's previous measurement to determine whether the user's weight has changed.

[0069] For example, in this embodiment of the present invention, when the user's weight changes, before determining whether the user's weight change is greater than or equal to a preset threshold, the method further includes: acquiring the user's first weight; the first weight is the user's weight through the electronic weighing device The current weight obtained; according to the first weight and the second weight, it is determined whether the user’s weight has changed; the second weight is the last time the user passed the The weight obtained by the electronic weighing device; if the first weight is different from the second weight, it is determined that the user's weight has changed; the weight change is obtained according to the weight difference between the first weight and the second weight; the weight change is obtained according to the obtained weight change To determine whether the weight change is greater than or equal to the preset threshold.

[0070] In the embodiment of the present invention, the first weight may be, for example, the current weight of the user when weighing this time. For example, the electronic weighing device is a body fat scale, and the first weight is the weight that the user weighed when the user is on the scale, for example, 75 kg. The second weight is the user's previous weight measured by the body fat scale except this measurement. For example, the last weight measured by the body fat scale was 73kg, that is, the first weight is different from the second weight At this time, the electronic weighing device can determine that the user's weight information has changed. According to the first weight and the second weight, it can be determined that the weight change is 2 kg. Then, according to the preset threshold, it is determined whether the weight change is greater than or equal to the preset threshold. For example, assuming that the preset threshold is 1 kg, the weight change amount is greater than the preset threshold.

[0071] S102: If the weight change is greater than or equal to the preset threshold, detect whether the power supply voltage of the electronic weighing device is less than or equal to the preset voltage; the preset voltage is the lowest voltage when the electronic weighing device is working normally;

[0072] In the embodiment of the present invention, when the weight change is greater than or equal to the preset threshold, the electronic weighing device can detect the power supply voltage in the power supply module of the electronic weighing device. The power supply module can be composed of several batteries, or other forms The power supply module is not limited in the embodiment of the present invention.

[0073] In the embodiment of the present invention, the power supply voltage of the power supply module can be detected by the device voltage measurement circuit. For example, the current measurement circuit can be formed by using a specific chip to overlap the peripheral circuit, or using a basic circuit structure for voltage measurement, or based on the measured voltage. The voltage data is calculated to obtain the corresponding current data, which is not limited in the embodiment of the present invention.

[0074] In the embodiment of the present invention, a possible voltage detection method is to obtain a voltage detection signal when the weight change is greater than or equal to a preset threshold; according to the voltage detection signal, obtain the current power supply voltage of the electronic weighing device; if the current If the supply voltage is less than or equal to the preset voltage, a prompt message is generated and output.

[0075] For example, voltage detection is performed by a specific control circuit. When the weight change is greater than or equal to a preset threshold, the processor of the electronic weighing device generates a control signal (ie, voltage detection signal) and sends the signal to the control At this time, the control circuit obtains the current power supply voltage of the electronic weighing device through the control circuit according to the control signal, and determines whether it is necessary to generate and output prompt information according to the detected power supply voltage.

[0076] In the embodiment of the present invention, it is also possible to determine whether to perform voltage detection according to the user's selection. For example, if the weight change is greater than or equal to a preset threshold, send a detection request instruction to the electronic communication device; the electronic communication device matches the electronic weighing device; receives The definite detection instruction sent by the electronic communication device obtains the voltage detection signal according to the definite detection instruction; the definite detection instruction is an instruction fed back based on the requested detection instruction.

[0077] In the embodiment of the present invention, the electronic communication device can be paired with the electronic weighing device. For example, the electronic communication device is a smart phone and the electronic weighing device is a body fat scale. The two are paired via Bluetooth, that is, the two can transmit data to each other via Bluetooth. When the weight change is greater than or equal to the preset threshold, the electronic weighing device sends a request detection instruction to the electronic communication device. The instruction can cause the electronic communication device to display related request information, for example, the request information is "whether voltage is detected". After the user confirms, the electronic communication device generates feedback information (that is, equivalent to a confirmation detection instruction), and sends the confirmation detection instruction to the electronic weighing device. After the electronic weighing device receives the definite detection instruction, it can generate a voltage detection signal, for example, a control signal for controlling the voltage detection circuit.

[0078] S103: If the supply voltage is less than or equal to the preset voltage, generate and output prompt information; the prompt information is used to indicate that the supply voltage is less than or equal to the preset voltage.

[0079] In the embodiment of the present invention, if the power supply voltage is less than or equal to the preset voltage, prompt information is generated, and the prompt information is sent to the electronic communication device. For example, the electronic communication device is a mobile phone, and the electronic weighing device sends a prompt message to the mobile phone to remind the user that the power of the electronic weighing device is insufficient at this time. For example, the prompt message may be "The body fat scale has insufficient power, please replace the battery".

[0080] Optionally, the electronic weighing device can also calculate the remaining power and output the information, for example, if the power supply voltage is less than or equal to the preset voltage, enter the low power consumption mode; according to the power supply voltage, obtain the remaining power of the electronic weighing device Power; according to the remaining power and the power consumption of the electronic weighing device in the low power mode, obtain the usable time of the electronic weighing device in the low power mode; generate and output prompt information according to the usable time.

[0081] In the embodiment of the present invention, when the power supply voltage of the electronic weighing device is insufficient, it can enter the low power consumption mode, for example, only to measure the weight data without measuring other data, or to turn off some functions, etc., the present invention The embodiment does not limit this.

[0082] When the electronic weighing device enters the low power consumption mode, the power consumption of the electronic weighing device at that time can be determined, for example, the power consumption per minute. When measuring the power supply voltage, the remaining power of the power supply module can also be obtained. In this way, according to the remaining power and the power consumption per minute, the time that the electronic weighing device can be used in the low power consumption mode can be determined. , Will include the duration information output, for example, the information can be sent to the user's mobile phone. For example, a possible message is "The body fat scale has a low battery and it can be used for 30 minutes. Please replace the battery in time." Of course, the above are only examples and do not limit the present invention.
