Technical Field

[0001] This application relates to the field of data processing technology, and in particular to a numerical display method, apparatus, computer equipment, and air purifier. Background Technology

[0002] Electrochemical sensors are commonly used in fields such as atmospheric environmental monitoring, indoor air quality monitoring, and healthcare, and can detect various gases including formaldehyde, ammonia, hydrogen sulfide, and sulfur dioxide. However, due to the long warm-up time required and the complex environments in which they are used, these sensors are prone to inaccurate detection, large fluctuations in detection values, and high failure rates.

[0003] When an electrochemical sensor has not been powered on and activated for a long time, the readings are prone to being too high when it is powered on again, and it usually takes a long time to return to normal. On the other hand, it is difficult to guarantee that the detection results are consistent with the detection values ​​before the power failure when the sensor is powered on again, resulting in large detection errors and low accuracy.

[0053] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0054] The numerical display method provided in this application can display numerical values ​​based on detection data, avoiding numerical jumps and improving the user experience.

[0055] Example 1

[0056] Many electrochemical sensors require a certain activation period, such as 24 hours, after initial use or restart after a power outage before they can accurately detect data. During normal use after activation, a 2-minute warm-up is needed for accurate data detection. If users activate the device at long intervals or for less than 24 hours each time, the sensor may operate in an incompletely activated state, resulting in initially higher values. It may take 2-3 minutes to detect and display the true electrochemical value. Even for devices that can quickly display electrochemical values, the sensor data during startup is unstable, sometimes showing values ​​that are too low or too high.

[0057] Figure 1 The diagram illustrates the implementation flow of a numerical display method provided by an embodiment of the present invention.

[0058] See Figure 1 The numerical display method provided in this embodiment of the invention may include steps 101 to 102.

[0059] Step 101: Receive the power-on command and obtain the standby time and the standby value before standby.

[0060] In some embodiments, step 101 includes:

[0061] When the electrochemical sensor is powered on, acquire the last displayed value Dend recorded during standby.

[0062] Step 102: Calculate the maximum value based on the standby time and standby value.

[0063] In some embodiments, step 102 includes:

[0064] The maximum value is calculated 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.

[0065] In a specific example, using time period T as the counting unit, the duration of this standby is counted as xT, and the displayed value does not exceed Dmax = Dend + ax, where a is a constant. That is, X = xT, A = a / T.

[0066] Optionally, T is set to 20 seconds and a is set to 0.001.

[0067] Step 103: Obtain the current detection value and determine the relationship between the current detection value and the maximum value.

[0068] Step 104: If the current detected value is greater than the maximum value, then display the maximum value.

[0069] In some embodiments, steps 103 and 104 include:

[0070] Within a preset startup duration, the current detection value is obtained in a loop, and the relationship between the current detection value and the maximum value is determined.

[0071] If the current detected value is greater than the maximum value, then the maximum value is displayed;

[0072] If the current detected value is less than or equal to the maximum value, then the current detected value is displayed;

[0073] Until the preset startup time is reached.

[0074] In some embodiments, the preset startup duration T0 is set to 2 minutes.

[0075] In some embodiments, displaying the current detection value if the current detection value is less than or equal to the maximum value includes:

[0076] Obtain the average value of the detected values ​​within the first preset time period;

[0077] If the average value of the detected values ​​is less than the pre-stored first threshold, the step of judging the relationship between the current detected value and the maximum value will not be executed, and the current detected value will be displayed directly.

[0078] In the method provided by this embodiment of the invention, if the average value of the detected values ​​within a first preset time period is less than a first threshold, it indicates that the current detected values ​​are generally small and will not reach the preset maximum value. Therefore, it is not necessary to continue to judge the relationship between the detected values ​​and the maximum value to avoid displaying values ​​that are too large.

[0079] In a specific example, if the mean of consecutive detections is small enough during the T0 time period, such as the mean being less than 0.04 within 10 seconds, then numerical constraints will no longer be applied using Dmax.

[0080] Specifically, the methods for calculating the mean include, but are not limited to, directly calculating the mean of multiple data points over a continuous period of time; calculating the mean of multiple data points after removing the maximum and minimum values ​​over a continuous period of time; and calculating the mean of multiple data points over a continuous period of time and then using that mean as a benchmark to calculate the mean of the value and the mean of two values ​​before and after that period of time.

[0081] Based on the above average calculations, the method provided by this embodiment of the invention can quickly and accurately display detection data to users, thereby improving the user experience.

[0082] Furthermore, if the standby time is long, such as more than one hour, then the value will not be limited by Dmax.

[0083] In some embodiments, the method provided by the present invention further includes:

[0084] The numerical values ​​are displayed according to a preset frequency;

[0085] The currently displayed value satisfies Dn+1≤Dn+Kn and Dn+1≥Dn-Jn and is always greater than zero, where Dn is the previous displayed value, Dn+1 is the current displayed value, Kn is a random number within the first preset interval, and Jn is a random number within the second preset interval.

[0086] In a specific example, the displayed values ​​are updated at a preset frequency, which can be selected as once every 3 seconds. To avoid sudden data changes during each update, the range of the new data is the range calculated based on the previous data.

[0087] In some embodiments, Dn+1 ≤ Dn+Kn, and Dn+1 ≥ Dn-Jn; where Kn and Jn are random numbers limited by the maximum change value. For example, if the maximum change value is 10, then Kn is a random number between 5 and 10, and Jn is a random number between 7 and 10. Furthermore, the displayed value Dn should be greater than zero at any given time.

[0088] Optionally, this method can be applied in devices such as air purifiers to improve the speed and accuracy of numerical display.

[0089] The method provided in this invention addresses the problem of large data fluctuations in electrochemical sensors during the preheating stage by calculating the average data over a continuous period to improve the speed and accuracy of displayed values.

[0090] Furthermore, this embodiment of the invention provides a fault recovery method for an electrochemical sensor, wherein a continuous period without data upload or where data upload fails verification is identified as a fault stage. Verification refers to the main control program verifying the sensor data by checking the frame header, frame length, command word, checksum, and frame tail.

[0091] Post-fault recovery primarily involves the main control program sending reset commands to the sensors at intervals until the sensors respond to the reset command. While waiting for a reset response, the program checks the data uploaded by the sensors to determine if it's a reset response. If not, it checks if the data is being uploaded normally, continuing this process until the fault is resolved.

[0092] The method provided in this invention is for sensors that operate outdoors for extended periods or are installed in air purifiers, and can ensure the normal operation of such devices during the fault recovery phase.

[0093] The method provided in this invention can solve the calibration and fault recovery problems of electrochemical sensor detection values ​​through auxiliary algorithms, improving the effectiveness, stability, and detection speed of the detection values. It limits the range of variation of the displayed values ​​of the electrochemical sensor under specific application conditions, achieving consistency and smoothness in the display of detection values, avoiding abnormal abrupt changes in display due to power outages or EFT interference, and improving the user experience.

[0094] Example 2

[0095] Figure 2 This diagram illustrates another implementation flow of the numerical display method provided in an embodiment of the present invention.

[0096] See Figure 2 In a specific example, the numerical display method provided by the embodiment of the present invention is implemented as follows.

[0097] After the electrochemical sensor is powered on, determine the time interval between power-off and power-on.

[0098] The upper limit of the display within a short period of time is calculated based on the displayed value when the computer is off and the shutdown time.

[0099] The data acquired each time, for example, every three seconds, must not differ too much from the previously displayed data. The specific sampled value is displayed under this constraint.

[0100] Traditional electrochemical sensors exhibit significant numerical fluctuations during the power-on phase. For example, if a sensor performs a test and displays the result every three seconds after power-on, and the initial reading is 0.050, but the reading changes to 0.100 after three seconds, the result will be a noticeable jump, giving users a negative impression.

[0101] Traditional electrochemical sensors also exhibit a tendency for the displayed value to jump after being powered on for an extended period of standby. For example, if the sensor is powered off or in standby mode when the displayed value is 0.050, and then powered on again, the displayed value may show 0.100, with a noticeable jump in the value.

[0102] Figure 3 This diagram illustrates another implementation flow of the numerical display method provided in an embodiment of the present invention.

[0103] See Figure 3 Taking formaldehyde detection as an example, the numerical display method provided in this embodiment of the invention is implemented as follows.

[0104] After powering on, check if it's the first power-on within one hour. If not, revert to the last displayed value Dend before the last power-off. Calculate the standby time xT between the last power-off and the current power-on, and use Dend and xT to calculate the current display limit Dmax.

[0105] In a specific example, using time period T as the counting unit, the duration of this standby is counted as xT, and the displayed value does not exceed Dmax = Dend + ax, where a is a constant. Optionally, T is set to 20 seconds, and a is set to 0.001.

[0106] If it is determined to be the first power-on within one hour, the sensor's detection data will be displayed directly, and the current display limit Dmax will be set to infinity.

[0107] The current formaldehyde value Dn is obtained from the sensor, and it is determined whether Dn exceeds Dmax. If Dn exceeds Dmax, then Dn = Dmax; otherwise, the value of Dn is not changed.

[0108] Dn is provided to the display module for display.

[0109] Furthermore, it is determined whether Dn is less than or equal to Dn-1 + Kn-1. If so, Dn is displayed directly; otherwise, Dn is set to Dn-1 + Kn-1 before being displayed. Here, Dn is the currently detected formaldehyde value, Dn-1 is the previous detected formaldehyde value, and Kn-1 is a random number limited by the maximum change value. For example, if the maximum change value is 10, then Kn-1 is a random number between 5 and 10. This random number is used to display the range of change between the current and previous formaldehyde values, thus avoiding abrupt changes in the displayed data.

[0110] Repeat the above steps until the boot time exceeds T0.

[0111] In summary, the numerical display method provided by the embodiments of the present invention can reduce the jump in the displayed value when the electrochemical sensor is powered on, avoid obvious abnormalities in the displayed value caused by interference factors, and avoid the problem of data inconsistency before and after power-on.

[0118] The numerical display module 204 is used to display the maximum value if the current detected value is greater than the maximum value.

[0119] In some embodiments, the maximum value calculation module 202 is specifically used for:

[0120] The maximum value is calculated 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.

[0121] In some embodiments, the numerical judgment module 230 and the numerical display module 204 are specifically used for:

[0122] Within a preset startup duration, the current detection value is obtained in a loop, and the relationship between the current detection value and the maximum value is determined.

[0123] If the current detected value is greater than the maximum value, then the maximum value is displayed;

[0124] If the current detected value is less than or equal to the maximum value, then the current detected value is displayed;

[0125] Until the preset startup time is reached.

[0126] In some embodiments, the numerical display module 204 is specifically used for:

[0127] Obtain the average value of the detected values ​​within the first preset time period;

[0128] If the average value of the detected values ​​is less than a pre-stored first threshold, the step of determining the relationship between the current detected value and the maximum value is skipped, and the current detected value is displayed directly.

[0129] In some embodiments, the device is further configured to:

[0132] In summary, the device provided in this embodiment of the invention can reduce the jump in the displayed value when the electrochemical sensor is powered on, avoid obvious abnormalities in the displayed value caused by interference factors, and avoid the problem of inconsistent data before and after power-on.
