Fig. 1 shows a flowchart of a power supply management method when a smart watch is charged.
As shown in fig. 1, the invention discloses a power supply management method for charging a smart watch, which comprises the following steps:
s102, acquiring charging connection state information, and judging whether to enter a charging connection state according to the charging connection state information;
s104, if so, entering a first power supply mode;
s106, acquiring first voltage information, and judging whether the first voltage information exceeds a preset first voltage threshold value;

s110, if yes, obtaining a second voltage threshold according to a preset communication instruction;
s112, judging whether the first voltage information exceeds the second voltage threshold value;
and S114, if so, entering a second power supply mode.
It should be noted that, first, the charging connection state information is a connection state indicating a charging interface of the smart watch, including a charging connection state indicating that there is a charging device to provide electric energy for the smart watch through the charging interface, and a non-charging connection state indicating that no charging device is connected to the charging interface of the smart watch. The first power supply mode refers to the mode that the charger supplies electric power to the circuit system of the intelligent watch and the connected peripheral equipment, and can be called a charger power supply mode, and in the mode, the charger supplies power to the circuit system and the peripheral equipment and provides charging service for the battery. When the charger is connected to a charging interface of the intelligent watch, namely in a charging connection state, the charger enters a first power supply mode through the electronic circuit switch.
Second, the first voltage information is a voltage value between the positive and negative terminals of the battery of the smart watch, and may be referred to as a battery voltage value. After the battery voltage is acquired through the electronic circuit, whether the battery voltage value exceeds a preset first voltage threshold value is judged. For example, in some applications, when the battery voltage is lower than 3.0 volts, the power supply requirement of the circuit system of the smart watch cannot be met, and the 3.0 volts is the preset first voltage threshold, which is set according to the circuit system of the smart watch.
And then, if the battery voltage exceeds a preset first voltage threshold, namely, the battery voltage can meet the electric energy supply requirement of the intelligent watch circuit system, acquiring the peripheral state information of the peripheral interface. The peripheral interface is an interface provided by the smart watch for driving and communicating with the peripheral device, and a TYPE-C interface, a USB interface, etc. can be generally used. The peripheral state information is a connection state of a peripheral interface of the intelligent watch, and comprises a peripheral connection state, wherein the peripheral connection state indicates that peripheral equipment is in a working state and is communicated with the intelligent watch, and a non-peripheral connection state indicates that the peripheral equipment which is not in the working state is communicated with the intelligent watch.
And finally, when the peripheral is in a peripheral connection state, communicating with the peripheral equipment through a preset communication instruction, and analyzing and calculating to obtain a second voltage threshold according to the communication information. The second voltage threshold is the lowest voltage value required to be provided by the battery in order to ensure the normal operation of the peripheral equipment when the battery is used for supplying power; that is, when the voltage of the battery exceeds the second voltage threshold, the power supply capability provided by the battery can ensure normal operation of the circuitry and the peripheral device of the smart watch, and at this time, the second power supply mode is set to be entered through the electronic circuit switch. The second power supply mode refers to a mode of supplying electric power to the circuit system of the smart watch and the connected peripheral equipment through a battery, and can be called a battery power supply mode, and the battery supplies power to the circuit system and the peripheral equipment in the mode.
In addition, in practical application, the charger converts the voltage value provided by 220 v mains supply or other power sources into a voltage value capable of providing electric energy for the smart watch, and the power source provided by the charger for the smart watch is unstable due to external interference of the mains supply or other power sources, so that the normal work of the smart watch, particularly the measurement accuracy of peripheral equipment, is affected. Compared with the prior art, the battery power supply of the intelligent watch has the characteristic of stable power supply, can better meet the power supply requirements of the intelligent watch and the peripheral equipment, and ensures the measurement accuracy of the peripheral equipment.
Fig. 2 shows a flowchart of power supply mode switching according to an embodiment of the present invention.
According to an embodiment of the present invention, as shown in fig. 2, further includes:
s202, when the second power supply mode is entered and the peripheral equipment is in the peripheral equipment connection state;
s204, judging whether the first voltage information is lower than a preset first voltage threshold value or not;
s206, if yes, entering the first power supply mode;
s208, if not, judging whether the first voltage information is lower than the second voltage threshold;
and S210, if yes, entering the first power supply mode.
It should be noted that, the second power supply mode refers to providing an electric power supply for the circuit system of the smart watch and the connected peripheral device through the battery, and may be referred to as a battery power supply mode; the peripheral connection state indicates that peripheral equipment is in a working state and is communicated with the intelligent watch. When the power supply mode is the battery power supply mode and the communication connection between the peripheral equipment and the intelligent equipment exists, judging whether the first voltage information is lower than a preset first voltage threshold value or not; the first voltage information is a voltage value between the positive end and the negative end of a battery of the intelligent watch, namely the battery voltage value. If the voltage value of the battery is lower than a preset first voltage threshold, the battery power supply is indicated to be incapable of meeting the power supply requirement of normal operation of the circuit system of the intelligent watch, and the power supply mode is switched to a first power supply mode, namely a charger power supply mode. If the battery voltage value is not lower than a preset first voltage threshold, namely the battery voltage can meet the electric energy supply requirement of the intelligent watch circuit system, judging whether the battery voltage value is lower than a second voltage threshold; the second voltage threshold is the lowest voltage value required to be provided by the battery in order to ensure the normal operation of the peripheral equipment when the battery is used for supplying power. When the voltage value of the battery is lower than the second voltage threshold value, the power supply capability provided by the battery does not meet the normal working requirements of the circuit system and the peripheral equipment of the intelligent watch, and the power supply mode is switched to the first power supply mode, namely the charger power supply mode.
Fig. 3 shows a flowchart for obtaining the second voltage threshold according to an embodiment of the present invention.
According to an embodiment of the present invention, as shown in fig. 3, the second voltage threshold is obtained according to a preset communication instruction, which specifically is:
s302, sending first instruction information and acquiring first feedback information fed back by peripheral equipment;
s304, obtaining first coding information according to the first feedback information;
s306, judging whether first power supply information of the peripheral equipment corresponding to the first coding information exists or not according to the first coding information;
s308, if yes, setting the second voltage threshold according to the first power supply information;
and S310, if not, obtaining the second voltage threshold according to a second communication instruction.
The intelligent watch communicates with the peripheral equipment through the peripheral interface, sends first instruction information to the peripheral equipment, and the peripheral equipment returns first feedback information according to the first instruction information and the coding information of the peripheral equipment. Obtaining first coding information of the peripheral equipment according to the first feedback information; wherein the first instruction information is an instruction for identifying the peripheral device, and the peripheral device is usually distinguished by a peripheral code, for example, the code 0x11 represents a blood oxygen device No. 1, and the code 0x21 represents a blood pressure device No. 1; the first feedback instruction comprises a peripheral code of the peripheral equipment; the first encoded information is encoded information of a peripheral device connected to the smart watch. Then, inquiring whether first power supply information of peripheral equipment corresponding to the first coding information is stored in the system according to the first coding information; the first power supply information is a battery voltage value required by the peripheral equipment in normal operation. The system stores the first power supply information of the common peripheral equipment so as to facilitate quick search and judgment. If the first power supply information exists, setting a second voltage threshold value by using the first power supply information; and if the first power supply information does not exist, sending a second communication instruction to the external equipment, and analyzing to obtain a second voltage threshold. The second voltage threshold is the lowest voltage value required to be provided by the battery in order to ensure the normal operation of the peripheral equipment when the battery is used for supplying power.
According to an embodiment of the present invention, the obtaining the second voltage threshold according to the second communication instruction specifically includes:
sending second instruction information and acquiring second feedback information fed back by the peripheral equipment;
obtaining first electrical parameter information of the peripheral equipment according to the second feedback information;
and searching a preset voltage supply and demand table according to the first electrical parameter information to obtain the second voltage threshold.
The intelligent watch communicates with the peripheral equipment through the peripheral interface, sends second instruction information to the peripheral equipment, and returns second feedback information according to the second instruction information and the electrical parameters during working. The first electrical parameter information is an electrical parameter of the peripheral equipment when in operation, including but not limited to a voltage value, a current value, a load impedance and the like. And inquiring a voltage supply and demand table preset in the system according to the first electrical parameter of the peripheral equipment to obtain a second voltage threshold. The second voltage threshold is the lowest voltage value required to be provided by the battery in order to ensure the normal operation of the peripheral equipment when the battery is used for supplying power. For example, when the voltage value is 3.3 volts and the current value is 100 milliamperes in the first electrical parameter information, the voltage value corresponds to the required battery voltage value of 3.5 volts. The voltage supply and demand table is prestored in the system according to the electronic characteristics of the circuit system.
According to an embodiment of the present invention, further comprising:
when the battery is in the second power supply mode, acquiring temperature information of the battery;
judging whether the temperature information exceeds a preset temperature threshold value or not;
if yes, setting to enter the first power supply mode.
It should be noted that, the smart watch is provided with a sensor for detecting temperature, and the sensor is used for detecting temperature information of the battery. When in the battery power supply mode, if the temperature information of the battery exceeds a preset temperature threshold value, the temperature is required to be prevented from rising continuously by switching the first power supply mode. After being switched to the first power supply mode, namely the charger power supply mode, the battery does not need to provide electric energy for the circuit system and the peripheral equipment of the intelligent watch, so that the work load is effectively lightened, and the temperature rising speed of the battery is slowed down, and even the temperature rising preventing effect is achieved.
According to an embodiment of the present invention, further comprising:
sending third instruction information to obtain third feedback information fed back by the peripheral equipment;
obtaining first periodic information according to the third feedback information;
judging whether first time information in the first period information exceeds a preset first time threshold value or not;
if yes, the power supply mode is repeatedly switched according to the first period information.
The intelligent watch communicates with the peripheral device through the peripheral interface, sends third instruction information to the peripheral device, and the peripheral device returns third feedback information according to the third instruction information and the working time period. The first period information is a time period of partial peripheral equipment when the detection task is executed, and the time period comprises detection duration and interval duration; the first time information is an interval duration. For example, the blood oxygen apparatus has a detection period of 100 milliseconds and an interval period of 0 seconds, and the time period is 100 milliseconds; the heart rate device detects 10 seconds in length and 50 seconds in interval, and the time period is 60 seconds. When the first time period exceeds a preset first time threshold, a mode of switching the power supply mode can be adopted to reduce the duration of the battery power supply mode. When the detection time period is in the detection time period phase, the battery power supply mode is set, and a stable power supply is provided for the peripheral equipment so as to ensure the detection stability; when the battery is in the interval duration stage, the battery is set to be in a charger power supply mode, the peripheral module is not in a detection state at the moment, the requirement on the stability of the power supply is not high, and the battery is only in a charging state, so that the charging speed is improved, and the service life of the battery is protected.
It is worth mentioning that the method further comprises:
when the peripheral equipment is in the peripheral equipment connection state and is in the first power supply mode, second voltage information is acquired;
judging whether the second voltage information is in a preset third voltage threshold range or not;
if yes, initializing first time length information;
if not, updating the first time length information according to the acquisition period of the second voltage;
judging whether the first time length information exceeds a preset first time length threshold value or not;
if yes, a first prompt message is sent to the terminal.
It should be noted that, when the power supply mode of the charger exists and the peripheral device performs the measurement task, the power supply voltage provided by the charger, that is, the charger voltage, is collected according to the preset time period and recorded as the second voltage information. The first time length information is a duration for recording that the charger voltage exceeds a preset range. Judging whether the voltage of the charger is in a preset third voltage threshold range or not; if yes, initializing first time length information; if not, the first time length information is updated according to the acquisition period, for example, the period of acquiring the charging voltage takes 100 milliseconds as the period, and the first time length information is incremented by 100 milliseconds each time. When the first time length information exceeds a preset first time length threshold value, the charger voltage stability degree can be indicated to not meet the measurement work requirement of the peripheral equipment, and first prompt information is sent to the terminal and used for prompting the user of the unstable work condition of the peripheral equipment.
It is worth mentioning that the method further comprises:
acquiring the first voltage information, and judging whether the first voltage information exceeds a preset third voltage threshold value;
if yes, entering a trickle charge mode and setting the trickle charge mode as a second power supply mode.
It should be noted that, the first voltage information is a battery voltage value, and it is determined whether the battery voltage value is higher than a preset third voltage threshold. If so, indicating that the battery is approaching a full state, a trickle charge mode, i.e., a low power charge mode, may be set to prevent a reduction in battery life due to overcharging of the battery. At this time, the battery power is sufficient to meet the working requirements of the smart watch and the peripheral, and the battery power mode can be switched.

The first power supply mode refers to the mode that the charger supplies electric power to the circuit system of the intelligent watch and the connected peripheral equipment, and can be called a charger power supply mode, and in the mode, the charger supplies power to the circuit system and the peripheral equipment and provides charging service for the battery. When the charger is connected to a charging interface of the intelligent watch, namely in a charging connection state, the charger enters a first power supply mode through the electronic circuit switch.
Second, the first voltage information is a voltage value between the positive and negative terminals of the battery of the smart watch, and may be referred to as a battery voltage value. After the battery voltage is acquired through the electronic circuit, whether the battery voltage value exceeds a preset first voltage threshold value is judged. For example, in some applications, when the battery voltage is lower than 3.0 volts, the power supply requirement of the circuit system of the smart watch cannot be met, and the 3.0 volts is the preset first voltage threshold, which is set according to the circuit system of the smart watch.
And then, if the battery voltage exceeds a preset first voltage threshold, namely, the battery voltage can meet the electric energy supply requirement of the intelligent watch circuit system, acquiring the peripheral state information of the peripheral interface. The peripheral interface is an interface provided by the smart watch for driving and communicating with the peripheral device, and a TYPE-C interface, a USB interface, etc. can be generally used. The peripheral state information is a connection state of a peripheral interface of the intelligent watch, and comprises a peripheral connection state, wherein the peripheral connection state indicates that peripheral equipment is in a working state and is communicated with the intelligent watch, and a non-peripheral connection state indicates that the peripheral equipment which is not in the working state is communicated with the intelligent watch.
And finally, when the peripheral is in a peripheral connection state, communicating with the peripheral equipment through a preset communication instruction, and analyzing and calculating to obtain a second voltage threshold according to the communication information. The second voltage threshold is the lowest voltage value required to be provided by the battery in order to ensure the normal operation of the peripheral equipment when the battery is used for supplying power; that is, when the voltage of the battery exceeds the second voltage threshold, the power supply capability provided by the battery can ensure normal operation of the circuitry and the peripheral device of the smart watch, and at this time, the second power supply mode is set to be entered through the electronic circuit switch. The second power supply mode refers to a mode of supplying electric power to the circuit system of the smart watch and the connected peripheral equipment through a battery, and can be called a battery power supply mode, and the battery supplies power to the circuit system and the peripheral equipment in the mode.

When the power supply mode is the battery power supply mode and the communication connection between the peripheral equipment and the intelligent equipment exists, judging whether the first voltage information is lower than a preset first voltage threshold value or not; the first voltage information is a voltage value between the positive end and the negative end of a battery of the intelligent watch, namely the battery voltage value. If the voltage value of the battery is lower than a preset first voltage threshold, the battery power supply is indicated to be incapable of meeting the power supply requirement of normal operation of the circuit system of the intelligent watch, and the power supply mode is switched to a first power supply mode, namely a charger power supply mode. If the battery voltage value is not lower than a preset first voltage threshold, namely the battery voltage can meet the electric energy supply requirement of the intelligent watch circuit system, judging whether the battery voltage value is lower than a second voltage threshold; the second voltage threshold is the lowest voltage value required to be provided by the battery in order to ensure the normal operation of the peripheral equipment when the battery is used for supplying power. When the voltage value of the battery is lower than the second voltage threshold value, the power supply capability provided by the battery does not meet the normal working requirements of the circuit system and the peripheral equipment of the intelligent watch, and the power supply mode is switched to the first power supply mode, namely the charger power supply mode.
According to the embodiment of the invention, the second voltage threshold is obtained according to a preset communication instruction, specifically:

judging whether first power supply information of peripheral equipment corresponding to the first coding information exists or not according to the first coding information;
if yes, setting the second voltage threshold according to the first power supply information;
if not, the second voltage threshold is obtained according to a second communication instruction.

Obtaining first coding information of the peripheral equipment according to the first feedback information; wherein the first instruction information is an instruction for identifying the peripheral device, and the peripheral device is usually distinguished by a peripheral code, for example, the code 0x11 represents a blood oxygen device No. 1, and the code 0x21 represents a blood pressure device No. 1; the first feedback instruction comprises a peripheral code of the peripheral equipment; the first encoded information is encoded information of a peripheral device connected to the smart watch. Then, inquiring whether first power supply information of peripheral equipment corresponding to the first coding information is stored in the system according to the first coding information; the first power supply information is a battery voltage value required by the peripheral equipment in normal operation. The system stores the first power supply information of the common peripheral equipment so as to facilitate quick search and judgment. If the first power supply information exists, setting a second voltage threshold value by using the first power supply information; and if the first power supply information does not exist, sending a second communication instruction to the external equipment, and analyzing to obtain a second voltage threshold. The second voltage threshold is the lowest voltage value required to be provided by the battery in order to ensure the normal operation of the peripheral equipment when the battery is used for supplying power.
According to an embodiment of the present invention, the obtaining the second voltage threshold according to the second communication instruction specifically includes:
sending second instruction information and acquiring second feedback information fed back by the peripheral equipment;
obtaining first electrical parameter information of the peripheral equipment according to the second feedback information;
and searching a preset voltage supply and demand table according to the first electrical parameter information to obtain the second voltage threshold.
The intelligent watch communicates with the peripheral equipment through the peripheral interface, sends second instruction information to the peripheral equipment, and returns second feedback information according to the second instruction information and the electrical parameters during working. The first electrical parameter information is an electrical parameter of the peripheral equipment when in operation, including but not limited to a voltage value, a current value, a load impedance and the like. And inquiring a voltage supply and demand table preset in the system according to the first electrical parameter of the peripheral equipment to obtain a second voltage threshold. The second voltage threshold is the lowest voltage value required to be provided by the battery in order to ensure the normal operation of the peripheral equipment when the battery is used for supplying power. For example, when the voltage value is 3.3 volts and the current value is 100 milliamperes in the first electrical parameter information, the voltage value corresponds to the required battery voltage value of 3.5 volts. The voltage supply and demand table is prestored in the system according to the electronic characteristics of the circuit system.
According to an embodiment of the present invention, further comprising:
when the battery is in the second power supply mode, acquiring temperature information of the battery;

if yes, setting to enter the first power supply mode.
It should be noted that, the smart watch is provided with a sensor for detecting temperature, and the sensor is used for detecting temperature information of the battery. When in the battery power supply mode, if the temperature information of the battery exceeds a preset temperature threshold value, the temperature is required to be prevented from rising continuously by switching the first power supply mode. After being switched to the first power supply mode, namely the charger power supply mode, the battery does not need to provide electric energy for the circuit system and the peripheral equipment of the intelligent watch, so that the work load is effectively lightened, and the temperature rising speed of the battery is slowed down, and even the temperature rising preventing effect is achieved.

sending third instruction information to obtain third feedback information fed back by the peripheral equipment;
obtaining first periodic information according to the third feedback information;

if yes, the power supply mode is repeatedly switched according to the first period information.
The intelligent watch communicates with the peripheral device through the peripheral interface, sends third instruction information to the peripheral device, and the peripheral device returns third feedback information according to the third instruction information and the working time period. The first period information is a time period of partial peripheral equipment when the detection task is executed, and the time period comprises detection duration and interval duration; the first time information is an interval duration.

When the first time period exceeds a preset first time threshold, a mode of switching the power supply mode can be adopted to reduce the duration of the battery power supply mode. When the detection time period is in the detection time period phase, the battery power supply mode is set, and a stable power supply is provided for the peripheral equipment so as to ensure the detection stability; when the battery is in the interval duration stage, the battery is set to be in a charger power supply mode, the peripheral module is not in a detection state at the moment, the requirement on the stability of the power supply is not high, and the battery is only in a charging state, so that the charging speed is improved, and the service life of the battery is protected.

It should be noted that, when the power supply mode of the charger exists and the peripheral device performs the measurement task, the power supply voltage provided by the charger, that is, the charger voltage, is collected according to the preset time period and recorded as the second voltage information. The first time length information is a duration for recording that the charger voltage exceeds a preset range. Judging whether the voltage of the charger is in a preset third voltage threshold range or not; if yes, initializing first time length information; if not, the first time length information is updated according to the acquisition period, for example, the period of acquiring the charging voltage takes 100 milliseconds as the period, and the first time length information is incremented by 100 milliseconds each time. When the first time length information exceeds a preset first time length threshold value, the charger voltage stability degree can be indicated to not meet the measurement work requirement of the peripheral equipment, and first prompt information is sent to the terminal and used for prompting the user of the unstable work condition of the peripheral equipment.
