Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
Fig. 1 is a schematic flow chart of a method for acquiring a remaining duration available to a device according to an embodiment of the present invention. The method for acquiring the available remaining time of the equipment comprises the following steps:
s101, acquiring the current power consumption speed of the detected device.
In particular, during use of the device under test, the battery in the device under test needs to be constantly discharged to power the various components. In the process of discharging the battery, the voltage of the battery or the current during discharging can be collected, and then the current power consumption speed of the detected equipment can be calculated by combining the discharging time.
And S102, acquiring the current residual capacity of the detected equipment.
In practice, a certain incidence relation exists between the voltage of the battery and the electric quantity of the battery, multiple discharge tests can be performed on the battery in the detected equipment in advance, and after the multiple discharge tests, the incidence relation between the voltage of the battery and the electric quantity of the battery can be obtained. In this embodiment, the current remaining power of the detected device may be obtained according to the collected current voltage of the battery in the detected device and the association relationship between the battery voltage and the power.
As shown in fig. 2, a voltage acquisition circuit according to an embodiment of the present invention is provided. In this embodiment, the voltage of the battery may be collected by the voltage collecting circuit shown in fig. 2. The voltage fluctuation can be caused by the plugging and unplugging of the battery, the collected voltage can be stabilized through an RC low-pass filter in the voltage collecting circuit, then the voltage can be further isolated and buffered due to the fact that the input impedance of a follow-up circuit of the operational amplifier connected in series is large, the output impedance is small, the voltage can be stably input into an Analog-to-Digital Converter (ADC) chip, and the ADC chip can obtain the voltage of the battery.
Further, the battery voltage U is collected when the battery is fully charged1At this time, the battery capacity Q11 is ═ 1; collecting battery voltage U when battery is empty2At this time, the battery capacity Q20. According to the battery discharge curve, the electric quantity and the voltage are basically in a linear relation, and a is 1/(U + b) calculated by a linear equation Q1-U2)，b＝-U2/(U1-U2). The battery voltage U can be measured in a period of 10 secondsxContinuously collecting, and obtaining the current battery electric quantity Q according to the linear equationx. And obtaining the power consumption speed V as delta Q/delta t according to the relation between the electric quantity change and the time.
Optionally, in this embodiment, the electric quantity and the battery voltage of the battery may also be obtained periodically, a linear regression model is used to perform regression analysis on the data, coefficients a and b of the regression model are obtained by a least square method, that is, a mean square error is minimized, and the accuracy of the correlation between the battery electric quantity and the battery voltage calculated by the linear regression method is higher.
And S103, acquiring the available remaining time of the detected equipment according to the remaining electric quantity and the current power consumption speed.
After the remaining power and the current power consumption speed are obtained, the ratio of the remaining power to the current power consumption speed can be obtained, and the ratio is the remaining duration available to the detected device. The remaining time length indicates how long the detected device can continue to work when the detected device discharges at the current power consumption speed in the using process.
For example, when the detected device is a wearable electrocardiograph device, after the remaining duration is obtained, whether the detected wearable electrocardiograph device can complete the data acquisition can be determined according to the remaining duration, if the data acquisition can not be completed, the acquisition can be stopped in time, and the waste of user time caused by the fact that the acquisition is needed again due to the fact that the acquired data is incomplete after the acquisition is avoided. Further, if the wearable electrocardio equipment supports charging, when the remaining time length cannot support completion of the acquisition, the wearable electrocardio equipment can be charged in time so as to ensure that the acquired data is effective.
It should be noted here that the detected device may be various portable terminal devices.
The method for acquiring the remaining time length available to the device according to the embodiment acquires the current remaining power of the device to be detected by acquiring the current power consumption speed of the device to be detected, and acquires the remaining time length available to the device to be detected according to the remaining power and the current power consumption speed. In the embodiment, in the using process of the detected device, the data on the battery in the detected device can be acquired in real time, so that the current electric quantity and the current power consumption speed can be calculated in real time, and the time that the detected device can continue to work at the current power consumption speed can be calculated. The usable residual time length is calculated according to the measured data, so that the obtained residual time length is more accurate.
Fig. 3 is a flowchart illustrating another method for acquiring a remaining duration available for a device according to an embodiment of the present invention. The remaining time period available for use by the apparatus comprises the steps of:
s201, identifying a currently adopted working mode of the detected equipment.
In this embodiment, the device to be detected is a wearable electrocardiograph device, and the method for acquiring the remaining time length available for the device provided in this embodiment is explained. The wearable electrocardio device comprises a plurality of sampling channels, namely the number of lead electrodes, and a plurality of sampling rates. The electrode number of the lead can support 5 electrodes, 7 electrodes and 10 electrodes, and the sampling rate can support 128Hz, 256Hz, 512Hz and 1024 Hz. Different working modes of the wearable electrocardio device correspond to different lead electrode numbers and different sampling rates. The consumption of electricity is also different in different operating modes. In this embodiment, different lead electrode numbers and different sampling rates may be combined in advance, and different combinations correspond to one working mode. For example, the number of leads can be configured as 7 electrodes, the sampling rate can be configured as 256Hz, and the 7 electrodes and 256Hz are combined into one working mode. Further, the basic power consumption speed in each operating mode can be obtained in a test mode. When the user uses the wearable electrocardio device for the first time, the actual power consumption speed of the user is updated from the basic power consumption speed as a starting point according to the actual power consumption situation in the use process of the user.
In this embodiment, when the user uses the wearable electrocardiograph device, the wearable electrocardiograph device is configured, that is, the number of lead electrodes and the sampling rate are configured, and according to the parameter configuration of the wearable electrocardiograph device, the current working mode adopted by the wearable electrocardiograph device can be identified. For example, the number of lead electrodes may be configured as 7 electrodes, and the sampling rate configured as 256 Hz.
S202, acquiring the initial power consumption speed of the detected device in the adopted working mode.
After the working mode adopted by the wearable electrocardio device is identified, the initial power consumption speed of the wearable electrocardio device under the working model can be obtained. And when the user is a new user, taking the basic power consumption speed in the working mode obtained by the test as the initial power consumption speed. And when the user is an old user who already uses the wearable electrocardio device, the last power consumption speed of the user recorded by the wearable electrocardio device can be used as the initial power consumption speed.
And S203, acquiring the power consumption in a preset period.
After the initial power consumption speed is obtained, the power consumption speed of the wearable electrocardio device is updated according to a preset period from the initial power consumption speed, and the current power consumption speed of the wearable electrocardio device is obtained.
Specifically, the actual power consumption of the wearable electrocardiograph device is detected in a preset period from the initial power consumption speed, and then the actual power consumption speed of the wearable electrocardiograph device is updated according to the actual power consumption condition of the wearable electrocardiograph device. In this embodiment, the power consumption in the preset period may be acquired according to the preset period, and the actual power consumption speed of the wearable electrocardiograph device is updated according to the power consumption in the preset period. Specifically, a first voltage at the beginning of the preset period and a second voltage at the end of the preset period are collected, then a first electric quantity at the beginning of the preset period and a second electric quantity at the end of the preset period are calculated according to an incidence relation between the voltage of the battery and the electric quantity, and then a difference value of the first electric quantity and the second electric quantity is obtained and used as electric consumption in the preset period.
And S204, calculating the power consumption speed in the preset period according to the power consumption in the preset period and the duration of the preset period.
And calculating the ratio of the power consumption in the preset period to the duration of the preset period, and taking the ratio as the power consumption speed in the preset period.
And S205, updating the current power consumption speed by using the power consumption speed in the preset period.
After the power consumption speed in the preset period is obtained, the current power consumption speed can be updated by using the power consumption speed in the preset period. Fig. 4 is a schematic flow chart illustrating a process of updating a current power consumption speed by using a power consumption speed in a preset period according to an embodiment of the present invention. The updating of the current power consumption speed by using the power consumption speed in the preset period comprises the following steps:
s301, calculating a first root mean square of the power consumption speed in the preset period and the current power consumption speed.
In this embodiment, an operation event performed on the wearable electrocardiograph device by the user needs to be detected in real time. If the operation event of the user is not detected in the preset period, a first root mean square of the power consumption speed in the preset period and the current power consumption speed can be calculated.
Specifically, after the wearable electrocardio device enters the monitoring state, an operation event of the user on the device can be detected in real time, and after the operation event is detected, the time point of the operation event can be started, namely, the time point is taken as the starting point, and a preset period is formed by timing according to the first time length. For example, the preset period may be 30 minutes. Further, after the preset period is reached, if the user operation is not detected, the power consumption in the preset period, that is, within 30 minutes, may be obtained, and then a ratio is made between the power consumption and a duration of the preset period, that is, a first time length, where the ratio is a power consumption speed in the preset period.
Further, root mean square calculation is performed on the power consumption speed W in the preset period and the current power consumption speed S to obtain a first root mean square S ', and then the value of the current power consumption speed is updated to the first root mean square S ', that is, S is equal to S '. The current power consumption speed S is the power consumption speed in the previous preset period.
For example, no operation event of the user is detected in N preset periods, and the power consumption speed in the first preset period is W1The current power consumption speed S is the initial power consumption speed S0W is to be1And the initial power consumption speed S0Calculating root mean square to obtain a first root mean square S in a first preset period1', update the current power consumption speed S to S1' when no operation event of the user is detected during the preset period again, the power consumption rate during the preset period is W2W is to be2And S1Performing root mean square calculation to obtain a first root mean square S in a second preset period2', updated current power consumption speed S equals S2'. By analogy, if no operation event of the user is detected in the mth preset period, the current power consumption speed updated after the mth preset period is as follows:
and S302, updating the value of the current power consumption speed to be a first root mean square.
In order to ensure that the current power consumption speed is more accurate, in this embodiment, the value of the current power consumption speed of the wearable electrocardiograph device is updated to the first root mean square.
In this embodiment, in a preset period, an operation event performed by a user on the wearable electrocardiograph device needs to be detected in real time. Such as lighting a screen, pressing keys to check electrocardiographic waveforms, etc., these operation events may cause the power consumption of the wearable electrocardiographic device to increase. Fig. 5 is a schematic flow chart illustrating a process of updating a current power consumption speed by using a power consumption speed in a preset period according to an embodiment of the present invention. After detecting the operation event of the user, the updating the current power consumption speed by using the power consumption speed in the preset period comprises the following steps:
s401, taking a difference value between the power consumption speed in the preset period and the current power consumption speed as an increment of the power consumption speed in the preset period caused by the operation event.
Specifically, when the wearable electrocardio device enters a monitoring state and starts to time, namely, when the wearable electrocardio device starts to work, the wearable electrocardio device starts to time according to a second time length to form a preset period. For example, the second length of time is 60 minutes. If the operation event of the user exists in the preset period, obtaining the increment of the power consumption speed caused by the operation event in the preset period according to the power consumption speed of the preset period and the current power consumption speed. Specifically, a difference between the power consumption speed in the preset period and the current power consumption speed is calculated, and the difference is used as an increment in the preset period.
S402, calculating a second root mean square of the increment in the preset period and the increment of the power consumption speed in the previous preset period.
After the increment in the preset period is obtained, root mean square calculation can be performed on the increment in the preset period and the increment in the previous preset period to obtain a second root mean square.
And S403, acquiring a value obtained by adding the current power consumption speed and the second root-mean-square, and updating the value of the current power consumption speed into the added value.
And after the current power consumption speed is added to the second root mean square, updating the value of the current power consumption speed into the added value.
For example, the increment is labeled as T, and the power consumption rate in a preset period is labeled as V. The power consumption speed in the first preset period is V1, and the current power consumption speed is S1I.e. the initial power consumption speed S0. Further, the increment T in the first preset period1＝V1-S0. Due to the initial value T0If 0, increment T1And T0After the root mean square calculation is carried out, a second root mean square T in the first preset period is obtained1', the current power consumption speed S in the first preset period1Is updated to S0+T1'. When the preset period is reached again, if the operation event of the user exists in the preset period, the increment T is added2And the increment T in the last preset period1Calculating root mean square to obtain a second root mean square T in the preset period2', the current power consumption speed S2Is updated to S1+T2'. And so on, increment T in the n +1 th preset periodn+1The calculation formula of' is as follows:
then according to the increment T in the n +1 preset periodn+1', obtaining the current power consumption speed S in the preset periodn+1Is Sn+T2'; wherein S isnThe power consumption rate in the previous preset period.
In this embodiment, when a user performs an operation event within a preset period, an increment of the power consumption speed caused by the operation event of the user may be calculated, and then the current power consumption speed is updated by the increment, so that the calculated remaining duration has better accuracy. By monitoring the operation events of the user, an increment of the power consumption speed corresponding to the use habit of the user can be formed, the power consumption speed of the user is corrected based on the increment, and the prediction accuracy rate of the residual duration of the user can be improved.
And S206, acquiring the current residual capacity of the detected equipment.
Further, after the current power consumption speed of the wearable electrocardiograph device which can be detected by the device is obtained, the current residual power of the wearable electrocardiograph device can be calculated according to the collected current voltage of the battery in the wearable electrocardiograph device and the incidence relation between the battery power and the battery voltage.
And S207, acquiring the available remaining time length of the detected equipment according to the remaining power and the current power consumption speed.
And acquiring a ratio between the residual electric quantity and the current power consumption speed, wherein the ratio is the available residual time length of the wearable electrocardio equipment.
And S208, judging whether the remaining time length is greater than or equal to the current remaining required time length.
In actual use, the user can set the monitoring duration of the wearable electrocardio device, namely the duration of the monitoring requirement of the wearable electrocardio device. The initial demand duration can be set by the user according to the monitoring demand of the user. In the use process of wearable electrocardio equipment, the current remaining demand duration can be monitored.
In this embodiment, in order to better complete monitoring so as to obtain effective monitoring data, after the remaining duration of the wearable electrocardiograph device is obtained, the remaining duration may be compared with the currently remaining required duration to determine whether the remaining duration can complete the monitoring.
If the remaining duration is greater than or equal to the current remaining required duration, continuing monitoring; if the remaining time period is lower than the currently remaining required time period, S209 is performed.
And S209, outputting alarm information.
If the remaining duration is less than the current remaining required duration, which indicates that the remaining duration is not enough to support completion of the monitoring, the wearable electrocardiograph device can send an alarm to the user so as to facilitate charging of the user, or stop the monitoring, thereby saving the time of the user.
In the embodiment, the current power consumption speed of the detected device is obtained to obtain the current remaining power of the detected device, and the usable remaining duration of the detected device is obtained according to the remaining power and the current power consumption speed. In the embodiment, in the using process of the detected device, the data on the battery in the detected device can be acquired in real time, so that the current electric quantity and the current power consumption speed can be calculated in real time, and the time that the detected device can continue to work at the current power consumption speed can be calculated. The usable residual time length is calculated according to the measured data, so that the obtained residual time length is more accurate.
Furthermore, after the remaining duration is obtained, whether the usable remaining duration of the detected equipment meets the requirements of the user can be judged, intelligent warning can be performed when the usable remaining duration of the detected equipment does not meet the requirements of the user, the user can conveniently perform corresponding processing, and user experience is improved.
Fig. 6 is a flowchart illustrating another method for acquiring a remaining duration that can be used by a device according to an embodiment of the present invention. On the basis of the above embodiment, after obtaining the remaining duration available to the device, the method further includes the following steps:
s501, receiving a display instruction.
The user can check the remaining duration of the wearable electrocardiograph device in real time, and specifically, can send a display instruction to the wearable electrocardiograph device, for example, the screen can be lighted by pressing a key.
And S502, displaying the remaining time length on a display screen according to the display instruction.
After receiving the display instruction, the screen may be lit, and the remaining duration may be displayed on the screen. After the user checks the remaining duration, whether corresponding measures are taken for the wearable electrocardio device or not can be determined according to the remaining duration and the remaining required duration in the monitoring process.
In the embodiment, according to the requirements and the operation of the user, the remaining duration of the detected equipment can be displayed for the user, the screen cannot be lightened constantly, and the electric quantity can be saved.
