Detailed Description
Hereinafter, exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. It should be apparent that the described embodiments are only some embodiments of the present application and not all embodiments of the present application, and it should be understood that the present application is not limited by the example embodiments described herein.
Fig. 1 is a flowchart of a maintenance reminding method for an air filter according to an exemplary embodiment of the present application. The air filter is connected with the air compressor and is used for filtering impurities in the air entering the air compressor; as shown in fig. 1, the maintenance reminding method of the air filter comprises the following steps:
step 110: and obtaining detection parameters of the air filter.
The detection parameters represent parameter results obtained by detection of a sensor arranged at the air filter. The parameter results may be operating parameters of the air filter during operation, such as air intake, flow, power, rotational speed, etc., and may also be state parameters of the air filter during operation or shutdown, such as temperature, pressure, etc. The application utilizes the sensor arranged on the air filter to detect the parameter result of the air filter in real time, thereby being capable of monitoring the running state of the air filter in real time so as to avoid missing the maintenance time.
Step 120: and according to the detection parameters, calculating the pumping efficiency of the air compressor.
The pumping efficiency is the air displacement of the air compressor (for example, the air intake amount per minute) in unit time. The application can detect the value of the corresponding detection parameter in real time after knowing the relation curve between the air pumping efficiency of the air compressor and the corresponding detection parameter, and obtains the air pumping efficiency of the air compressor by conversion based on the relation curve between the air pumping efficiency of the air compressor and the corresponding detection parameter, thereby obtaining the air pumping efficiency of the air compressor.
Step 130: and if the inflation efficiency is lower than a preset efficiency threshold, sending a maintenance reminding signal of the air filter.
Because the air inflation is the main function of the air compressor, the application judges the maintenance time of the air filter according to the air inflation efficiency, namely, the maintenance time of the air filter is determined based on the functional effect and the efficiency of the air compressor, so that the air filter can be more fit with the actual requirement. Therefore, when the air pumping efficiency is lower than the preset efficiency threshold value, the air pumping efficiency and the air pumping effect of the air compressor are poor, and at the moment, the air filter needs to be maintained or overhauled, and then a maintenance reminding signal of the air filter is sent out to remind a user to timely overhaul and maintain so as to ensure the normal work of the air compressor and simultaneously ensure the service life of the air compressor. Specifically, the maintenance alert signal may be an audible alert (e.g., a beep), or a visual alert (e.g., a flashing light of one or more colors).
In an embodiment, the efficiency threshold comprises a first efficiency threshold and a second efficiency threshold, wherein the first efficiency threshold is less than the second efficiency threshold; the specific implementation manner of the step 130 may be: if the inflation efficiency is lower than the second efficiency threshold, sending a cleaning reminding signal of the air filter; and if the inflation efficiency is lower than the first efficiency threshold, sending a maintenance reminding signal of the air filter.
If the efficiency threshold is set to be larger, the air compressor can be used continuously when the air compressor has higher air pumping efficiency when the air pumping efficiency of the air compressor is lower than the efficiency threshold, and if the air compressor is used for maintaining the air filter at the moment, certain overmaintenance is obviously caused, so that the maintenance cost is increased; if the efficiency threshold is set smaller, the air compressor has low air pumping efficiency when the air pumping efficiency is lower than the efficiency threshold, and the air compressor can be operated for a period of time in a poor environment or state, so that the air compressor is worn to a certain extent, and the service life of the air compressor is obviously not facilitated. In order to solve the technical problem, the application provides an efficiency threshold interval (namely, an interval range in which a first efficiency threshold and a second efficiency threshold are respectively used as a lower limit and an upper limit), and when the air inflow (namely, the air pumping efficiency) of the air compressor in unit time falls in the efficiency threshold interval (namely, the air pumping efficiency of the air compressor is lower than the second efficiency threshold and is higher than the first efficiency threshold), the air pumping efficiency of the air compressor can meet the basic requirement, and at the moment, a cleaning reminding signal of an air filter can be sent to remind a user to clean the air compressor so as to improve the working efficiency and the effect of the air compressor. If the air pump efficiency of the air compressor exceeds the efficiency threshold interval (namely, the air pump efficiency of the air compressor is lower than the first efficiency threshold), the air pump efficiency of the air compressor is indicated to be incapable of meeting the basic operation requirement of the air compressor, and a maintenance reminding signal of the air filter is sent out at the moment to remind a user to timely maintain the air filter so as to avoid the air compressor from being damaged due to continuous operation of the air compressor in a poor environment or state.
According to the maintenance reminding method for the air filter, provided by the application, the detection parameters of the air filter are obtained; the detection parameters represent parameter results obtained by detection of a sensor arranged at the air filter; according to the detection parameters, the inflation efficiency of the air compressor is calculated; if the inflation efficiency is lower than a preset efficiency threshold, a maintenance reminding signal of the air filter is sent out; the air filter is used for judging whether the air filter needs maintenance or not by detecting the parameters of the air filter in real time so as to calculate the air pumping efficiency of the air compressor, and a maintenance reminding signal is sent out when the air filter needs maintenance so as to remind a user of timely maintenance, so that the accuracy of a maintenance period can be improved, the waste of excessive maintenance can be reduced, and the service environment of the air compressor can be ensured so as to prolong the service life of the air compressor.
Fig. 2 is a flowchart of a maintenance reminding method for an air filter according to another exemplary embodiment of the present application. As shown in fig. 2, before step 110, the maintenance reminding method of the air filter may further include:
step 140: and calibrating the air filter to obtain a relation curve between the pumping efficiency of the air compressor and the detection parameters of the air filter.
According to the application, the air filter is calibrated in an experimental mode to obtain the relation curve between the air pumping efficiency of the air compressor and the detection parameters of the air filter, namely, the air compressor and the air filter of the same type are calibrated in an experimental scene to obtain the relation curve between the air pumping efficiency of the air compressor and the detection parameters of the air filter, so that the air pumping efficiency of the air compressor can be obtained through real-time conversion according to the detected parameter values in the actual detection process.
It should be understood that the application can also calibrate the relation curve between the pumping efficiency and the detection parameters according to the historical data of the air compressor and the air filter of the same type, and the relation curve between the pumping efficiency and the detection parameters can be obtained according to the historical data calibration by recording the value of the relevant detection parameters and the corresponding pumping efficiency of the air filter in the actual operation process due to certain distinction between the experimental environment and the actual operation environment. Preferably, the application can comprehensively calibrate the relation curve between the air pumping efficiency and the detection parameter by combining the historical data and the experimental data so as to further improve the accuracy of the relation curve between the air pumping efficiency and the detection parameter.
Fig. 3 is a flowchart of a maintenance reminding method for an air filter according to another exemplary embodiment of the present application. The sensor comprises a vacuum degree sensor, and the vacuum degree sensor is used for detecting the vacuum degree in the air filter; as shown in fig. 3, the step 140 may include:
step 141: the experiment is used for calibrating a relation curve between the inflating efficiency of the air compressor and the dust holding capacity of the air filter.
Specifically, the relation curve between the air pumping efficiency of the air compressor and the dust holding capacity of the air filter can be calibrated through an ash pumping experiment, wherein the dust holding capacity refers to the quantity of dust or dust which can be held or carried by a container or space, and the relation curve is generally used for describing performance indexes of products such as an air purifier, a dust collector, a filter element and the like; the larger the dust holding capacity, the more effective the product can filter and remove dust particles in the air, providing better air quality. As for the air filter, the larger the dust holding amount is, the more dust in the air filter is, and the dust can block the air inlet hole of the air filter, so that the air pumping efficiency of the air compressor is reduced, and therefore, the air pumping efficiency (the air inlet amount in unit time) of the air compressor and the dust holding amount of the air filter are inversely related to each other, as shown in fig. 4 (the air inlet amount in fig. 4 is the air pumping efficiency).
Step 142: the experiment is used for calibrating a relation curve between the vacuum degree and the dust holding capacity of the air filter.
Specifically, the application can calibrate a relation curve between the vacuum degree and the dust holding capacity of the air filter through an ash lifting experiment, wherein the vacuum degree refers to the difference degree between the air pressure inside an object and the atmospheric pressure, and the higher the vacuum degree is, the lower the internal air pressure is, and the larger the difference between the internal air pressure and the atmospheric pressure is. For the air filter, the larger the dust holding amount is, the more dust in the air filter is indicated, and the dust can block the air inlet hole of the air filter, so that the air in the air filter is reduced, and the vacuum degree in the air filter is increased, therefore, the vacuum degree of the air filter and the dust holding amount are positively correlated, and the air filter is particularly shown in fig. 5.
Step 143: and calculating a relation curve between the pumping efficiency of the air compressor and the detection parameters of the air filter according to the relation curve between the pumping efficiency and the dust holding quantity, the relation curve between the vacuum degree and the dust holding quantity and the relation curve between the vacuum degree and the voltage of the vacuum degree sensor.
Specifically, since the parameter detected by the vacuum sensor is a voltage, the voltage reflects the vacuum degree in the space detected by the vacuum sensor, that is, the voltage value of the vacuum sensor and the vacuum degree in the air filter are in a one-to-one correspondence (positive correlation), as shown in fig. 6. After knowing the relation curve between the pumping efficiency and the dust holding amount of the air compressor, the relation curve between the vacuum degree and the dust holding amount, and the relation curve between the vacuum degree in the air filter and the voltage of the vacuum degree sensor, the relation curve (inverse relation) between the pumping efficiency and the detection parameter of the air compressor can be calculated according to the relation curve between the pumping efficiency and the dust holding amount, the relation curve between the vacuum degree and the dust holding amount, and the relation curve between the vacuum degree in the air filter and the voltage of the vacuum degree sensor, as shown in fig. 7. In one embodiment, the implementation manner of the step 143 is: and calculating the relation curve between the pumping efficiency and the voltage of the vacuum sensor of the air compressor according to the relation curve between the pumping efficiency and the dust holding quantity, the relation curve between the vacuum degree and the dust holding quantity and the relation curve between the vacuum degree and the voltage of the vacuum sensor. The relation curve between the pumping efficiency of the air compressor and the voltage of the vacuum sensor is obtained through calibration, and the pumping efficiency of the air compressor can be converted after the voltage value of the vacuum sensor is read.
Fig. 8 is a flowchart of a maintenance reminding method for an air filter according to another exemplary embodiment of the present application. As shown in fig. 8, the step 130 may include:
step 131: and if the inflation efficiency is lower than the efficiency threshold, or the service time of the air filter exceeds a preset duration threshold, or the driving mileage of the vehicle carrying the air filter exceeds a preset mileage threshold, sending a maintenance reminding signal of the air filter.
The application can judge the maintenance time of the air filter from multiple aspects or dimensions such as the inflation efficiency, the using time, the driving mileage and the like of the air compressor, thereby obtaining more accurate maintenance time. Specifically, the efficiency threshold, the duration threshold and the mileage threshold can be preset, and when the pumping efficiency of the air compressor is lower than the efficiency threshold, or the service time of the air filter exceeds (is greater than) the duration threshold, or the driving mileage of the vehicle carrying the air filter exceeds (is greater than) the mileage threshold, that is, when any one index of the three dimensions reaches the preset threshold, the maintenance time of the air filter is judged to be reached.
It should be understood that other strategies may be adopted to determine the maintenance time of the air filter, for example, the air filter is mainly determined, that is, if the air pump efficiency is higher than the efficiency threshold, the duration threshold and the mileage threshold are set to be larger values, and if the air pump efficiency is lower than the efficiency threshold, the air filter is determined to have arrived at the maintenance time, and a maintenance reminding signal of the air filter is sent out; for another example, the application can also perform weighted average on three indexes of the air-pumping efficiency, the using time and the driving mileage to obtain a comprehensive index value, and compare the comprehensive index value with a preset index threshold value to judge the maintenance time of the air filter.
Fig. 9 is a flowchart of a maintenance reminding method for an air filter according to another exemplary embodiment of the present application. The maintenance mode of the air filter comprises the steps of replacing the air filter; as shown in fig. 9, after step 131, the maintenance reminding method of the air filter may further include:
step 150: after the air filter is replaced, the using time length and the driving mileage are cleared.
After the air filter is replaced, a new air filter is obtained by replacement, and the use duration and the driving mileage are cleared to zero at the moment so as to avoid misoperation of sending a maintenance reminding signal when the accumulated use duration and the accumulated driving mileage exceed a preset threshold value. The service time of the air filter and the driving mileage of the vehicle are recorded again after the air filter is replaced, so that the accuracy of the maintenance time determination of the air filter is improved.
Fig. 10 is a flowchart of a maintenance reminding method for an air filter according to another exemplary embodiment of the present application. The maintenance mode of the air filter comprises the steps of cleaning the air filter; as shown in fig. 10, after step 131, the maintenance reminding method of the air filter may further include:
step 160: after the air filter is cleaned, if the using time exceeds the time threshold, the time threshold is increased, and/or if the driving distance exceeds the mileage threshold, the mileage threshold is increased.
Because the operational environment of air filter probably is abominable to lead to the dust on the air filter more and block up, then lead to the inflating efficiency of air compressor machine lower, can clear up the air filter at this moment and can continue to use, thereby avoid changing the air filter, with reduction maintenance cost. And after the air filter is cleaned, if the using time length or the driving mileage exceeds a preset threshold value, in order to avoid the situation that whether the user really needs maintenance or not is unclear due to the fact that maintenance is always reminded, the application can adjust the time length threshold value or the driving mileage threshold value (for example, the exceeding threshold value is increased by 30 percent) so as to ensure that the using time length and the driving mileage after cleaning do not exceed the corresponding threshold values.
It should be understood that after the maintenance reminding signal is sent out, the maintenance reminding device can be manually maintained by a user (including replacement of an empty filter, cleaning of the empty filter and the like), and the use duration and the driving range or the adjustment duration threshold value or the driving range threshold value are manually cleared after maintenance, and of course, the maintenance reminding device can also automatically clear the use duration and the driving range or the adjustment duration threshold value or the driving range threshold value according to the maintenance content (which can be manually indicated or automatically detected and judged by the user).
