An embodiment of the present invention provides a method for correcting output of a dust sensor, and referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the method for correcting output of a dust sensor according to the present invention.
In this embodiment, the dust sensor output correction method includes the following steps:
step S10: and acquiring the operation time length, the accumulated dust value, the dust compensation value and the updated count value of the dust sensor.
It should be noted that, the execution main body of this embodiment may be the dust sensor output correction device, and the dust sensor output correction device may be a device such as a single chip microcomputer or a microcomputer, or may be another device that can achieve the same or similar functions.
It should be noted that the dust sensor may be installed in the air purification apparatus, the air purification apparatus may further be provided with a data storage and a counter, the data storage may be an Electrically Erasable Programmable Read Only Memory (EEPROM), the operation time, the accumulated dust value, the dust compensation value, and the update count value of the dust sensor may be obtained by reading the start time, the accumulated dust value, and the dust compensation value of the dust sensor recorded in the data storage, reading the update count value in the counter, and then calculating the operation time of the dust sensor according to the start time and the current time of the dust sensor.
In practical use, in order to reasonably utilize the usable times of each storage block in the data memory and prolong the service life of the data memory, a cyclic reading method can be adopted for reading data from the data memory, and a cyclic writing method can be adopted for writing data into the data memory.
The cyclic reading method comprises the steps of continuously detecting whether a reading task exists or not, when the reading task exists, determining a page address and a data address corresponding to data to be read according to the reading task, determining a current storage area according to the page address and the data address, trying to read the data in the current storage area, checking whether the read data are normal or not after reading, if the read data are not normal, trying to read again, and if the data cannot be normally read after multiple attempts, giving up reading the data in the current storage area, and restoring the page address and the data address to a state before reading; if the data is normal, the data in the backup storage area corresponding to the current storage area is tried to be read again, whether the data is normal or not can be verified after reading, if the data is normal, the currently read data is directly returned, if the data is not normal, re-reading is tried, if the data cannot be normally read after multiple attempts, the data reading is abandoned, and the page address and the data address are restored to the state before reading. The specific number of attempts of the multiple attempts may be set according to actual needs, for example: the setup was aborted after 5 repeat attempts.
The circular writing method can be that whether a writing task exists is continuously detected, when the writing task exists is detected, data to be written, a page address and a data address are determined according to the writing task, a current storage area is determined according to the page address and the data address, the data to be written are tried to be written in the current storage area, whether the writing is normal or not is verified after the writing, if the writing is not normal, the data is tried to be read again, if the data cannot be read normally after multiple times of trying, the writing of the data to be written in the current storage area is abandoned, and the page address and the data address are restored to a state before the writing; if the data is normal, trying to write data into the backup storage area corresponding to the current storage area, and checking whether the data writing is normal after the data writing, if the data writing is normal, ending the flow, if the data writing is not normal, trying to rewrite the data, if the data cannot be normally written after multiple attempts, giving up writing the data to be written, and restoring the page address and the data address to the state before writing. The data to be written, the page address and the data address are determined according to the writing task, so that the historical page address used when the data are written last time is searched for and is increased by one to obtain the page address, and the data address required by data storage is determined according to the data to be written and the data writing starting sequence number. The specific number of attempts of the multiple attempts may be set according to actual needs, for example: the setup was aborted after 5 repeat attempts.
It can be understood that, because the writing adopts a circular writing method, the writing is not performed on a certain storage block in the data memory, but the storage blocks in the data memory are circularly utilized, the maximum read-write times of the storage blocks in the data memory can be ensured to be utilized to the maximum extent, and the service life of the data memory is prolonged.
Step S20: and if the operation time length meets the preset compensation condition, acquiring the effective dust value of the dust sensor.
It should be noted that the measured value of the dust sensor is generally stable after the dust sensor is turned on for a certain time, and therefore, after the operation duration reaches the preset stable duration, it is determined that the operation duration meets the preset compensation condition, where the preset stable duration may be set by a developer according to different values of the dust sensor, for example: for the dust sensor of model a, it is determined according to an experiment that the measured value is stable after generally operating for 20 seconds, and then the preset stable time duration can be set to be 20 seconds. The obtaining of the effective dust value of the dust sensor may be obtaining a measurement value of the current dust sensor, and taking the obtained measurement value as the effective dust value.
In practical use, the step of obtaining the effective dust value of the dust sensor may be to obtain the effective dust value of the dust sensor every preset time period, and perform the following steps, for example: and after the operation time length meets the preset condition, taking 1 second as preset, taking 1 second as a preset time period, acquiring the effective dust value of the dust sensor once every 1 second, and executing the subsequent steps.
Step S30: and when the effective dust value is larger than or equal to the dust compensation value, clearing the accumulated dust value and the updated count value.
It can be understood that, if the effective dust value is greater than or equal to the dust compensation value, it can be said that there are many environmental dust pollutants and dust compensation is already needed, and therefore, the accumulated dust value and the updated count value for calculating the updated dust compensation can be cleared. The clearing of the accumulated dust value and the update count value may be setting the accumulated dust value recorded in the data memory to 0 and setting the update count value recorded in the counter to 0.
Step S40: and when the accumulated dust value and the updated count value are cleared, determining a real dust output value of the dust sensor according to the effective dust value and the dust compensation value so as to realize output correction of the dust sensor.
It can be understood that after the zero clearing is completed, the effective dust value may be corrected by using the dust compensation value to obtain a real dust output value, so as to correct the output value of the dust sensor, where determining the real dust output value of the dust sensor according to the effective dust value and the dust compensation value may be to subtract the dust compensation value from the effective dust value, and use the subtracted result as the real dust output value.
Further, in order to facilitate reasonable adjustment of the dust compensation value, after step S20, the method may further include:
when the effective dust value is smaller than the dust compensation value, updating the accumulated dust value according to the effective dust value to obtain a current accumulated dust value, and adding one to the updated count value to obtain a current updated count value; and if the current updating count value is less than or equal to a preset updating threshold value, returning to the step of acquiring the effective dust value of the dust sensor.
It should be noted that, if the effective dust value is smaller than the dust compensation value, it may be indicated that the content of dust pollutants in the environment may be low, the dust compensation value may be set to be high, and the dust compensation value may need to be adjusted. The preset update threshold may be set according to actual needs, for example: the preset update threshold is set to 30.
In practical use, the accumulated dust value is updated according to the effective dust value to obtain a current accumulated dust value, the updated count value is increased by one, the updated count value can be obtained by adding the accumulated dust value and the effective dust value, the sum obtained by adding is taken as the current accumulated dust value, the original accumulated dust value in the data memory is updated to the current accumulated dust value, the updated count value is increased by one to obtain the current updated count value, and the updated count value in the counter is updated to the current updated count value.
It can be understood that, if the current update count value is less than or equal to the preset update threshold value, it indicates that the duration of the effective dust value being less than the dust compensation value is still short, and it is not possible to determine whether the dust compensation value needs to be adjusted.
Further, in order to reasonably adjust the dust compensation value, in this example, after the step of updating the accumulated dust value according to the effective dust value when the effective dust value is smaller than the dust compensation value to obtain the current accumulated dust value, and adding one to the updated count value to obtain the current updated count value, the method may further include:
if the current updating count value is larger than a preset updating threshold value, updating the dust compensation value according to the current updating count value and the current accumulated dust value; and when the updating of the dust compensation value is finished, clearing the current updating count value and the current accumulated dust value, and returning to the step of acquiring the effective dust value of the dust sensor.
It can be understood that, if the current update count value is greater than the preset update threshold value, it may be determined that the effective dust value is continuously smaller than the dust compensation value within a period of time, and it may be determined that the dust compensation value is set to be possibly higher, and at this time, the dust compensation value may be updated according to the current accumulated dust value and the current update count value.
It can be understood that after the dust compensation value is updated according to the current accumulated dust value and the current updated count value, the current accumulated dust value and the current updated count value may be cleared, and the step of obtaining the effective dust value of the dust sensor is returned to continuously monitor whether the dust compensation value needs to be adjusted.
In practical use, the updating of the dust compensation value according to the current update count value and the current accumulated dust value may be to calculate a target dust compensation value through a preset compensation update formula, and then update the dust compensation value in the data storage to the target dust compensation value.
The preset compensation update formula may be:
TOFFSET＝DUSTALL/Ta-λ
wherein, TOFFSETIs a target dust compensation value; DUSTALLThe current accumulated dust value is obtained; t isaUpdating the count value for the current time; λ is a preset compensation coefficient, and is a positive integer, and can be set according to actual conditions, for example: λ ═ 5.
In the embodiment, the operation time length, the accumulated dust value, the dust compensation value and the updated count value of the dust sensor are obtained; if the operation time length meets the preset compensation condition, acquiring an effective dust value of the dust sensor; when the effective dust value is larger than or equal to the dust compensation value, clearing the accumulated dust value and the updated count value; and when the accumulated dust value and the updated count value are cleared, determining the real dust output value of the dust sensor according to the effective dust value and the dust compensation value so as to realize the output correction of the dust sensor. The dust compensation value can be obtained by continuously correcting the dust sensor in the operation process, and the dust compensation value is adopted to correct the effective dust value when the output value of the dust sensor is determined, so that the influence caused by dust deposition can be avoided as much as possible, and the output of the dust sensor is more accurate.
Referring to fig. 3, fig. 3 is a schematic flow chart of a dust sensor output calibration method according to a second embodiment of the present invention.
Based on the first embodiment described above, the dust sensor output correction method of the present embodiment further includes, after the step S40:
step S50: and when the dust sensor meets a preset initialization condition, comparing the dust compensation value with a preset dust compensation threshold value.
It should be noted that the preset initialization condition may be a preset condition for determining whether parameter initialization adjustment is required, the preset dust compensation threshold may be a maximum value of a preset dust compensation value, and if the dust compensation value exceeds the preset compensation threshold, it may be determined that the dust sensor has accumulated too much dust and cannot be used continuously.
Further, in order to reasonably determine whether parameter initialization needs to be performed on the dust sensor, before step S50 in this embodiment, the method may further include:
acquiring the current operation time length of the dust sensor, and determining whether the dust sensor meets a parameter adjustment condition according to the current operation time length; when the dust sensor meets the parameter adjusting condition, judging that the dust sensor meets a preset initialization condition; or when the dust sensor does not meet the parameter adjustment condition and detects that the cleaning completion mark exists, judging that the dust sensor meets the preset initialization condition.
It should be noted that the current operation duration may be the sum of the historical operation duration of the dust sensor and the operation duration of the current start, that is, the total usage duration of the dust sensor. In actual use, all starting moments and all closing moments of the dust sensor can be recorded, historical operating duration is obtained according to all the starting moments and the closing moments, and then the historical operating duration is added with the operating duration after the starting, so that the current operating duration is obtained. Determining whether the dust sensor meets the parameter adjustment condition according to the current operation time length may be that the dust sensor is judged to meet the parameter adjustment condition every time the current operation time length reaches a certain time length, such as: taking 30 minutes as an example, when the current operation time reaches 30 minutes, it is determined that the dust sensor meets the parameter adjustment condition, that is, when the current operation time reaches 30 × n (n is a positive integer) minutes, it is determined that the dust sensor meets the parameter adjustment condition.
It can be understood that if the dust sensor meets the parameter adjustment condition, it indicates that parameter initialization is required, and therefore, when the dust sensor meets the parameter adjustment condition, it can be determined that the dust sensor meets the preset initialization condition.
It should be noted that the cleaning completion flag may be a flag generated when the user cleans or replaces the dust sensor, and if the user cleans or replaces the dust sensor, parameter initialization is also required, so that when the dust sensor does not satisfy the parameter adjustment condition and detects that the cleaning completion flag exists, it may be determined that the dust sensor satisfies the preset initialization condition.
Further, in order to reasonably update the dust accumulated value and facilitate the parameter initialization of the dust sensor, before step S50, the method may further include:
acquiring a dust accumulated value, a clean air accumulated amount and a clean air count value of the dust sensor; updating the accumulated clean air amount according to the real dust output amount, and adding one to the count value of the clean air to obtain the current count value of the clean air; when the current clean air count value meets a preset accumulated updating condition, updating the dust accumulated value according to the clean air accumulated amount and the current clean air count value; and when the updating of the dust accumulated value is finished, clearing the clean air accumulated amount and the current clean air count value, and executing the step of comparing the dust compensation value with a preset dust compensation threshold value when the dust sensor meets a preset initialization condition.
The dust integrated value, the clean air integrated amount, and the clean air count value of the dust sensor may be obtained by reading the dust integrated value and the clean air integrated amount of the dust sensor in the data storage, and reading the clean air count value in the counter. The updating of the accumulated amount of clean air according to the actual dust output amount may be comparing the actual dust output amount with a preset clean standard value, subtracting the preset clean standard value from the actual dust output amount to obtain an output amount difference value when the actual dust output amount is greater than the preset clean standard value, adding the accumulated amount of clean air to the output amount difference value, taking the sum as the current accumulated amount of clean air, and updating the accumulated amount of clean air in the data storage to the current accumulated amount of clean air. The incrementing of the clean air count value to obtain the current clean air count value may be incrementing the clean air count value to obtain the current clean air count value, and updating the clean air count value in the counter to the current clean air count value. The preset cleaning standard value may be a constant preset by a developer, for example: the preset clean label value is set to 10.
It should be noted that, when the current clean air count value is greater than or equal to the preset cumulative update threshold, it may be determined that the current clean air count value satisfies the preset cumulative update condition, where the preset cumulative update threshold may be set according to actual needs, for example: the preset cumulative update threshold is set to 60. When the current clean air count value meets the preset cumulative update condition, updating the dust cumulative value according to the clean air cumulative amount and the current clean air count value may be to obtain an average clean air output amount by dividing the clean air cumulative amount by the current clean air count value, and when the average clean air output amount is greater than 0, adding the average clean air output amount and the dust cumulative value to obtain a current dust cumulative value, and updating the dust cumulative value in the data storage to the current dust cumulative value.
It is understood that, when the update of the dust accumulation value is completed, the accumulated clean air amount and the current clean air count value recorded in the data storage may be cleared, so that the accumulation may be continued subsequently, and the subsequent steps may be performed.
Further, in order to timely detect and prompt the user to replace the dust sensor when the dust sensor fails, after step S50, the method may further include:
when the dust compensation value is larger than or equal to a preset dust compensation threshold value, judging that the dust sensor fails, and generating a sensor failure report according to the dust compensation value; and saving and displaying the sensor failure report.
It can be understood that if the dust compensation value is greater than or equal to the preset dust compensation threshold value, it is described that the dust compensation amount of the dust sensor has reached the preset dust compensation amount maximum value, and therefore, it can be determined that the dust sensor has failed, a sensor failure report can be generated according to the dust compensation value, the sensor failure report is stored for tracing the reason, and the sensor failure report is displayed to prompt a user that the dust sensor has failed at present and needs to be cleaned or replaced.
Step S60: and when the dust compensation value is smaller than a preset dust compensation threshold value, acquiring a dust accumulated value of the dust sensor.
It can be understood that if the dust compensation value is smaller than the preset dust compensation threshold value, it indicates that the dust sensor does not fail, and therefore, the dust accumulated value of the dust sensor can be obtained.
In practical use, the acquiring of the dust accumulated value of the dust sensor may be reading the dust accumulated value of the dust sensor in a data storage.
Step S70: and if the real dust output value is greater than a preset cleaning standard value and the dust accumulated value is greater than a preset accumulated threshold value, initializing parameters and returning to the step of acquiring the effective dust value of the dust sensor.
It should be noted that the preset accumulation threshold may also be set in advance by a developer, and if the dust accumulation value is greater than the preset accumulation threshold, it indicates that the dust sensor has been operated for a long time in an environment with a high dust pollutant content, and parameter adjustment is required.
It can be understood that if the real dust output value is greater than the preset clean standard value, it indicates that the dust pollutant content in the current environment is higher, and the dust accumulated value is greater than the preset accumulated threshold value, it indicates that the dust sensor has been operated for a long time in an environment with a higher dust pollutant content, and therefore, the parameter initialization needs to be performed on the parameter to conform to the current environment.
In practical use, the parameter initialization may be performed by adding the dust compensation value recorded in the data storage to a preset clean standard value to obtain a target dust compensation value, updating the dust compensation value recorded in the data storage to the target dust compensation value, clearing the dust accumulation value and the clean air accumulation amount recorded in the data storage when the updating is completed, and clearing the clean air count value recorded in the counter.
In the embodiment, when the dust sensor meets a preset initialization condition, the dust compensation value is compared with a preset dust compensation threshold value; when the dust compensation value is smaller than a preset dust compensation threshold value, acquiring a dust accumulated value of the dust sensor; and if the real dust output value is greater than a preset cleaning standard value and the dust accumulated value is greater than a preset accumulated threshold value, performing parameter initialization on the dust sensor, and returning to the step of acquiring the effective dust value of the dust sensor. The parameters of the dust sensor are continuously analyzed in the operation process of the dust sensor, the parameters of the dust sensor are initialized according to the analysis result, and the corresponding dust compensation value is adjusted, so that the corrected output value of the dust sensor is more accurate.
