According to the numerical value display method, numerical value display can be performed based on detection data, numerical value jump is avoided, and user experience is improved.
Embodiment 1,
When many electrochemical sensors are started again after first use or power failure, the electrochemical sensors need to be activated for a certain time after power-up, such as twenty-four hours, so that data can be accurately detected; during normal use after activation, 2 minutes of preheating is required to accurately detect data. If the user starts the related equipment once at a longer time interval or uses the related equipment for less than twenty-four hours each time, the sensor may work in an underactivated state, the first detection value of the electrochemical sensor is larger, and 2-3 minutes are required to detect and display the actual electrochemical value. For devices capable of rapidly displaying electrochemical values, the sensor detection data during the start-up phase is also unstable, and there are cases of low or high.
Fig. 1 shows a schematic implementation flow chart of a numerical display method according to an embodiment of the present invention.
Referring to fig. 1, the method for displaying a numerical value according to the embodiment of the present invention may include steps 101 to 101.
Step 101: and receiving a starting instruction, and acquiring standby time and standby values before standby.
In some embodiments, step 101 comprises:
when the electrochemical sensor is powered on, the last display value Dend recorded in standby is obtained.
Step 102: and calculating a maximum value based on the standby time and the standby value.
In some embodiments, step 102 comprises:
calculating the maximum value based on dmax=dend+ax, where Dmax is the maximum value, dend is the standby value, a is a constant coefficient, and X is the standby time.
In a specific example, the duration of the standby is counted as xT with the time period T as a counting unit, and the display value does not exceed dmax=dend+ax, where a is a constant. I.e. x=xt, a=a/T.
Alternatively, T takes 20 seconds and a takes 0.001.
Step 103: and obtaining a current detection value, and judging the magnitude relation between the current detection value and the maximum value.
Step 104: and if the current detection value is larger than the maximum value, displaying the maximum value.
In some embodiments, steps 103 and 104 comprise:
circularly executing in a preset starting time to obtain a current detection value, and judging the magnitude relation between the current detection value and the maximum value;
if the current detection value is larger than the maximum value, displaying the maximum value;
if the current detection value is smaller than or equal to the maximum value, displaying the current detection value;
until the preset starting time is reached.
In some embodiments, the preset activation time period T0 takes a value of 2 minutes,
in some embodiments, displaying the current detected value if the current detected value is less than or equal to the maximum value comprises:
acquiring a detection value average value in a first preset duration;
if the average value of the detected values is smaller than a pre-stored first threshold value, the step of judging the relationship between the current detected value and the maximum value is not executed any more, and the current detected value is directly displayed.
In the method provided by the embodiment of the invention, if the average value of the detected values in the first preset time period is smaller than the first threshold value, the current detected values are smaller as a whole and cannot reach the preset maximum value, and the operation of judging the relationship between the detected values and the maximum value is not needed to be continued so as to avoid the display of the excessive value.
In a specific example, during the T0 period, if the average of the continuous detection occurs sufficiently small, e.g., the average is less than 0.04 in 10 seconds, the numerical limitation by Dmax is no longer performed.
Specifically, the mean value calculating method includes, but is not limited to, directly calculating a plurality of data mean values in a continuous time; calculating a plurality of data average values after removing the maximum value and the minimum value in a period of continuous time; after calculating the average value of a plurality of data in a period of continuous time, calculating the average value of the value and the front and rear numerical values in the period by taking the average value as a reference.
Through the mean value calculation, the method provided by the embodiment of the invention can be used for rapidly and accurately displaying the detection data for the user and improving the use experience.
Further, if the standby time is long, for example, exceeds one hour, the numerical limitation is not performed by Dmax.
In some embodiments, the method provided by the invention further comprises:
numerical value display is carried out according to preset frequency;
the current display value satisfies Dn+1 is less than or equal to Dn+Kn and Dn+1 is more than or equal to Dn-Jn and is constantly greater than zero, wherein Dn is the previous display value, dn+1 is the current display value, kn is a random number in a first preset interval, and Jn is a random number in a second preset interval.
In a specific example, the display value is updated at a preset frequency, which may be selected to be updated once for 3 seconds. In order to avoid data mutation in the process of each update, the value range of the new data is calculated according to the last data.
In some embodiments, dn+1 is less than or equal to Dn+Kn, and Dn+1 is less than or equal to Dn-Jn; where Kn and Jn are random numbers limited by a maximum variation value, e.g., 10, then Kn is a random number between 5 and 10 and Jn is a random number between 7 and 10. And the display value Dn should be greater than zero at any time.
Alternatively, such methods are applied in air purifiers and the like to improve the speed and accuracy of numerical display.
Aiming at the problem of large data fluctuation of the electrochemical sensor in the preheating stage, the method provided by the embodiment of the invention adopts a mode of calculating the data average value in continuous time to improve the speed and accuracy of displaying the numerical value.
Further, the embodiment of the invention provides a fault recovery method of an electrochemical sensor, wherein continuous time data-free uploading or data uploading cannot be judged to be a fault stage through verification. The verification means that the main control program performs frame header, frame length, command word, verification code and frame tail on the sensor data.
And the recovery after the fault mainly comprises the step of sending a reset command to the sensor within the interval time of the main control program until the sensor responds to the reset command. And in the period of waiting for the reset response, judging whether the data uploaded by the sensor is the reset response, and if not, judging whether the data is normally uploaded until the fault is recovered.
The method provided by the embodiment of the invention aims at the sensor which works outdoors or is arranged in the air purifier for a long time, and can ensure the normal operation of the device in the fault recovery stage.
The method provided by the embodiment of the invention can solve the problems of calibration and fault recovery of the detection value of the electrochemical sensor through an auxiliary algorithm, and improves the effectiveness, stability and detection speed of the detection value. The display numerical value of the electrochemical sensor is limited in the change range under the specific application condition, the consistency and smoothness of the display of the detection value are realized, abnormal abrupt change of the display caused by power failure or EFT interference is avoided, and the use experience of a user is improved.
Embodiment II,
Fig. 2 is a schematic flow chart of another implementation of the numerical display method according to the embodiment of the present invention.
Referring to fig. 2, in a specific example, the implementation procedure of the numerical display method provided by the embodiment of the present invention is as follows.
After the electrochemical sensor is started, the interval time from shutdown to startup is judged.
And calculating the display upper limit in a short time based on the shutdown display numerical value and the shutdown time.
The data acquired every time, for example, three seconds, is not allowed to be too far from the last displayed data, and a specific sampled value is displayed under the limitation of this condition.
The numerical value display of the traditional electrochemical sensor has large numerical value variation in the starting-up stage, for example, the numerical value is detected and displayed once every three seconds after starting up, and if the numerical value is displayed for the first time of 0.050 and displayed for 0.100 after three seconds, the numerical value can be obviously hopped, so that negative impression is brought to a user.
The traditional electrochemical sensor also has the condition that the display of numerical value jumps after long-time standby, for example, the power-off or standby is carried out when the display numerical value is 0.050, the electrochemical sensor is powered off, for example, the display of 0.100 is carried out after the detection of the power-on again, and the condition of numerical value jumps is obvious.
Fig. 3 is a schematic flow chart of another implementation of the numerical display method according to the embodiment of the present invention.
Referring to fig. 3, taking formaldehyde detection as an example, the implementation process of the numerical display method provided by the embodiment of the invention is as follows.
Judging whether the first startup is within 1 hour after startup, and if the first startup is not within 1 hour, recalling the last display value Dend before the last shutdown. And counting the standby time xT between the last shutdown and the current startup, and calculating the upper limit Dmax of the current display through Dend and xT.
In a specific example, the duration of the standby is counted as xT with the time period T as a counting unit, and the display value does not exceed dmax=dend+ax, where a is a constant. Alternatively, T takes 20 seconds and a takes 0.001.
If the first power-on within one hour is judged, the detection data of the sensor are directly displayed, and the upper limit Dmax of the current display is set to be infinity.
And acquiring the current formaldehyde value Dn from the sensor, and judging whether the Dn exceeds Dmax. If Dn exceeds Dmax, then let dn=dmax, and if not, then not change Dn value.
And providing Dn for the display module to display.
Further, whether Dn is smaller than or equal to Dn-1+Kn-1 is judged, if so, dn is displayed directly, and if not, dn=Dn-1+Kn-1 is displayed. Wherein Dn is the formaldehyde value currently detected, dn-1 is the last formaldehyde value detected, kn-1 is a random number limited by the maximum change value, for example, the maximum change value is 10, and Kn-1 is a random number between 5 and 10. The change amplitude of the current formaldehyde value and the last formaldehyde value is displayed through the random number, so that jump of display data is avoided.
The above steps are circularly executed until the starting time exceeds T0.
In summary, the numerical display method provided by the embodiment of the invention can reduce jump of the display value when the electrochemical sensor is powered on, avoid obvious abnormality of the display value caused by interference factors, and avoid the problem of inconsistent data before and after power on.
