Based on the implementation architecture shown in fig. 1, the present embodiment provides a method for treating filter screen filth blockage, which is executed by the electronic device shown in fig. 1, and the following describes in detail the steps of the method for treating filter screen filth blockage provided in the present embodiment based on the structure diagram of the electronic device 100 shown in fig. 1. Referring to fig. 2, the method for treating filth blockage of a filter screen according to the present embodiment includes steps S101 to S103.
Step S101: and acquiring the air inlet speed and the air outlet speed of the air conditioner, environmental parameters of the environment where the air conditioner is located and the accumulated time of the cleaned filter screen.
The air outlet and the air inlet of the air conditioner can be provided with air speed sensors, and the air inlet speed and the air outlet speed of the air conditioner can be obtained through the air speed sensors.
In this embodiment, the environmental parameter may be a contaminant concentration, an ambient humidity, an air temperature, and the like. Optionally, in this embodiment, the environmental parameter is a pollutant concentration, where the pollutant concentration includes concentrations of particulate matter, gaseous matter, volatile matter, semi-volatile matter, and the like.
Optionally, an environment monitoring sensor may be disposed in the air conditioner, and the environment parameter of the environment where the air conditioner is located is obtained through the environment monitoring sensor.
In this embodiment, the accumulated time after the filter screen is cleaned can be obtained by recording the cleaning time of the filter screen and then calculating according to the recorded cleaning time and the current time of the acquired data.
In an embodiment, if the filter screen is manually disassembled and cleaned, the first startup time after the filter screen is cleaned may be recorded, or the disassembly time of the filter screen may be recorded, and then the accumulated time after the filter screen is cleaned is obtained according to the recorded time and the current time of acquiring the data.
In an embodiment, if the filter screen is automatically cleaned, the time for automatically cleaning the filter screen may be recorded, and then the accumulated time length after cleaning the filter screen is obtained according to the recorded time and the current time for acquiring the data.
Step S102: and calculating the filth blockage value of the filter screen according to the air inlet speed, the air outlet speed, the accumulated time and the environmental parameters.
The filth blockage of the filter screen can affect the air outlet speed and the air inlet speed of the air conditioner, the filth blockage of the filter screen can be affected by environmental parameters and the accumulated time, the more the filth blockage is, the greater the influence on the air outlet speed and the air inlet speed of the air conditioner is, the worse the environment is, the longer the accumulated time is, and the more the filth blockage is. Therefore, the dirty blockage value is calculated by combining the air outlet speed, the air inlet speed, the environmental parameters and the accumulated time of the air conditioner, and the detection accuracy is improved.
In an optional implementation manner, in view of different influences of the environmental parameter, the accumulated time, the air intake speed, and the air outlet speed on the filth blockage value, different weights may be set according to the influence specific gravity on the environmental parameter, the accumulated time, the air intake speed, and the air outlet speed in this embodiment, for example, the influence specific gravity of the environmental parameter and the accumulated time is large, the weight may be set to 0.3 for the environmental parameter and the accumulated time, and the influence specific gravity of the air intake speed and the air outlet speed is small, and the weight may be set to 0.2 for the air intake speed and the air outlet speed. After the environmental parameter, the accumulated time, the air inlet speed and the air outlet speed are set with corresponding weights, the environmental parameter, the accumulated time, the air inlet speed and the air outlet speed can be weighted and summed to obtain a filth blockage value, namely, the filth blockage value is 0.3+ the accumulated time 0.3+ the air inlet speed 0.2+ the air outlet speed 0.2.
In an embodiment, in order to facilitate calculation of the data, the values of the environmental parameter, the accumulated duration, the air inlet speed, and the air outlet speed may be directly multiplied, and the product of the values of the environmental parameter, the accumulated duration, the air inlet speed, and the air outlet speed is used to obtain the filth blockage value, i.e., the filth blockage value is the environmental parameter.
In an embodiment, in order to facilitate calculation of the data, the values of the environmental parameter, the accumulated time, the air inlet speed, and the air outlet speed may be directly added, and the filth blockage value is obtained by summing the values of the environmental parameter, the accumulated time, the air inlet speed, and the air outlet speed, that is, the filth blockage value is equal to the environmental parameter + the accumulated time + the air inlet speed + the air outlet speed.
Step S103: and judging whether the filter screen needs to be cleaned or not according to the filth blockage value.
After the air inlet speed and the air outlet speed of the air conditioner, the environmental parameters of the environment where the air conditioner is located and the accumulated time after the filter screen is cleaned are obtained, the filth blockage value of the filter screen can be calculated according to the air inlet speed, the air outlet speed, the accumulated time and a plurality of data indexes of the environmental parameters, and the accuracy of the data is improved. And after the filth blockage value is obtained, whether the filter screen needs to be cleaned or not can be judged according to the filth blockage value, so that cleaning prompt is carried out, a user is reminded to pay attention to filth blockage of the filter screen, the filter screen is cleaned in time, and the service performance of the air conditioner is guaranteed.
In this embodiment, the dirty blockage value is an index reflecting the dirty blockage condition of the air conditioner filter screen, when the dirty blockage value is larger, it indicates that the dirty blockage of the air conditioner filter screen is serious, and the performance of the air conditioner is affected, and the air conditioner filter screen needs to be cleaned, and when the dirty blockage value is smaller, it indicates that the dirty blockage of the air conditioner filter screen has a small effect on the performance of the air conditioner, and the cleaning is not needed. Therefore, the filter screen can be determined whether to be cleaned or not by judging the size of the dirty value.
The filter screen filth blocking processing method provided by the embodiment comprises the steps of obtaining air inlet speed of an air conditioner, air outlet speed, environmental parameters of the environment where the air conditioner is located and accumulated time after the filter screen is cleaned, calculating filth blocking values of the filter screen according to the air inlet speed, the air outlet speed, the accumulated time and various indexes of the environmental parameters, judging whether the filter screen needs to be cleaned according to the filth blocking values, improving accuracy of data, reminding a user of paying attention to filth blocking of the filter screen when the filter screen is filth blocked, timely cleaning the filter screen, and ensuring using performance of the air conditioner.
In view of actual use, the acquired air inlet speed, air outlet speed and environmental parameters of the environment may have accidental errors, time periods can be set for ensuring the validity of data, the air inlet speed, the air outlet speed and the environmental parameters in each time period are collected for multiple times in the running process of the air conditioner after the filter screen is cleaned, and the average value of the air inlet speed, the air outlet speed and the environmental parameters in each time period is used as a data index of the time period. For example, assuming that the set time period is 1 hour, after the air conditioner starts to operate, the air intake speed, the air outlet speed and the environmental parameters of the air conditioner are monitored, and then counted once every 1 hour, the average values of the air intake speed, the air outlet speed and the environmental parameters collected for a plurality of times within 1 hour are calculated, the average value is used as the data index within the 1 hour, that is, the average value of the air intake speed within 1 hour is used as the index of the air intake speed within the 1 hour, the average value of the air outlet speed within 1 hour is used as the index of the air outlet speed within the 1 hour, and the average value of the environmental parameters within 1 hour is used as the index of the environmental parameters within the 1 hour.
Correspondingly, when the accumulated time length after the filter screen is cleaned is calculated, the end time point of the set time period, namely the statistical time point, is also used as the current time for calculation. For example, the cleaning time of the filter screen is 10 points, and if the statistics is performed once every 1 hour, and the intake air speed, the exhaust air speed and the environmental parameter of the air conditioner from 11 points to 12 points are counted at 12 points to obtain the average value of the intake air speed, the exhaust air speed and the environmental parameter of the air conditioner within one hour from 11 points to 12 points, the accumulated time after the filter screen is cleaned is two hours from 10 points to 12 points.
According to the filter screen filth blockage processing method provided by the embodiment, data in the set time period are collected for multiple times through the set time period, accidental errors of the data are avoided, and the effectiveness of the data is guaranteed.
It can be understood that, with the filter screen filth blockage processing method provided in this embodiment, the data index may also be calculated in other manners for the data in each time period, for example, different weights may also be given to the data acquired multiple times in each time period, and the data index in each time period is obtained by performing weighted average on the data acquired multiple times in each time period. For another example, the data in each time period may also be collected in real time, and the collected data is predicted through a set time series algorithm, such as ARIMA, to obtain a data index of each time period.
After the air inlet speed and the air outlet speed of the air conditioner, the environmental parameters of the environment where the air conditioner is located and the accumulated time after the filter screen is cleaned are obtained, the filth blockage value of the filter screen can be obtained through calculation according to the air inlet speed, the air outlet speed, the accumulated time and the environmental parameters.
In one embodiment, please refer to fig. 3, the filth blockage value of the filter screen can be obtained through steps S201 to S203 according to the air inlet speed, the air outlet speed, the accumulated time and the environmental parameters.
Step S201: and calculating a target difference value of the air inlet speed and the air outlet speed.
The difference between the air inlet speed and the air outlet speed can be calculated to obtain the difference between the air inlet speed and the air outlet speed, and then the absolute value of the difference is used as a target difference.
Step S202: and calculating a dirty blocking proportion coefficient according to the target difference and the initial difference obtained in advance.
The initial difference is the difference between the air inlet speed and the air outlet speed when the filter screen is started for the first time after being cleaned. It will be appreciated that an initial difference may be calculated after each cleaning of the screen, and that the initial difference will vary with the number of times the screen is cleaned. And for the air conditioner used for the first time, calculating the initial difference value of the air inlet speed and the air outlet speed when the air conditioner operates for the first time.
It should be noted that the initial difference is also an absolute value of a difference between the air inlet speed and the air outlet speed.
In this embodiment, the dirty blockage proportion coefficient can be calculated by the following formula according to the target difference value and the initial difference value:
wherein, X1 is a dirty blockage proportion coefficient, X is an initial difference value, and X is a target difference value.
