Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. Every other embodiment that can be obtained by a person skilled in the art without making creative efforts based on the embodiments of the present application falls within the protection scope of the present application.
In order to enable those skilled in the art to use the present disclosure, the following embodiments are given in conjunction with a specific application scenario "abnormal condition monitoring of an air conditioning filter element on a vehicle air conditioning system". It will be apparent to those skilled in the art that the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the present application, such as in the on-board air conditioning systems of various vehicles, such as cars, passenger cars, tractors, and the like. While the present application is described primarily in the context of an air conditioning filter anomaly monitoring case on an onboard air conditioning system of an excavator, it should be understood that this is but one exemplary embodiment.
The air conditioner filter screen is excessively dusty and is stuck to be blocked, so that the air output of the air conditioner is reduced, and even the refrigerating capacity of the air conditioner is reduced, so that an internal air filter element on a vehicle-mounted air conditioning system equipped for the excavator needs to be maintained according to the working time of the excavator, whether the internal air filter element is replaced or not is considered according to the actual use condition, the method completely depends on visual inspection and experience of after-sale workers of the excavator to judge, large errors are easily caused due to more unstable factors, and time and labor are wasted. Based on the actual pressure difference between the inner side and the outer side of the filter element, the actual air speed at the air outlet pipeline of the air conditioner and the actual service time of the filter element, the three parameters related to the service state of the filter element are comprehensively considered, so that an operator can receive the state information of the filter element in real time and make relatively accurate judgment, the abnormal filter element can be timely replaced, and the air quality in a cab of the excavator is ensured.
In a first aspect, an embodiment of the present application provides a monitoring method for an air conditioner filter element, please refer to fig. 1, where fig. 1 is a flowchart of the monitoring method for the air conditioner filter element provided in the embodiment of the present application, and as shown in fig. 1, the monitoring method includes:
s110, acquiring a preset first pressure difference threshold value of the inner side and the outer side of the filter element, a first air speed threshold value of the air outlet pipeline of the air conditioner and a service time threshold value of the filter element, and acquiring actual pressure difference of the inner side and the outer side of the filter element, actual air speed of the air outlet pipeline of the air conditioner and actual service time of the filter element in real time when the air conditioner works.
In the embodiment of the application, the first pressure difference threshold, the first wind speed threshold and the service time threshold are all preset thresholds inside the vehicle-mounted air conditioning system, and a specific obtaining method of the preset thresholds is not specifically limited, and may be preset thresholds set by engineers according to engineering experience, or preset thresholds corresponding to optimal detection precision may be determined through limited air conditioner filter screen detection experiments, or preset thresholds corresponding to optimal detection precision may be determined through limited computer simulation experiments. However, the specific numerical values of the first pressure difference threshold, the first wind speed threshold and the service time threshold are determined according to effective working data of a large number of filter elements, wherein the effective working data which can be referred to is data obtained under the normal service condition of the filter elements, and the abnormal conditions that the filter elements are in the service process, such as a large hole is damaged in the filter screen, or the filter screen is almost completely blocked, are eliminated.
Under the normal working condition of the air conditioner, the actual pressure difference between the inner side and the outer side of the filter element, the actual air speed at the air outlet pipeline of the air conditioner and the actual service time of the filter element are acquired in real time, the actual air speed and the actual service time of the filter element are compared with the first pressure difference threshold value, the first air speed threshold value and the service time threshold value respectively, and the working state of the air conditioner filter element is analyzed according to the comparison result.
It needs to be supplemented that the actual pressure difference between the inner side and the outer side of the filter element, the actual wind speed at the air outlet pipeline of the air conditioner and the actual service time of the filter element are selected as three parameters for monitoring whether the air conditioner filter element is abnormal or not in work, and the actual pressure difference between the inner side and the outer side of the filter element is used for illustration, when the filter element has a leak opening or a fault that the filter element is not installed, air directly enters the inner side of the filter element from the outer side of the filter element without being filtered by the filter element, and at the moment, the air flow of the inner side of the filter element is basically the same as the air flow of the outer side of the filter element, namely, the actual pressure difference between the inner side and the outer side of the filter element is very small and is close to 0; if the filter screen of the filter element is nearly completely blocked due to the materials of the filter element, the air outside the filter element cannot enter the inner side of the filter element through the filter element, and no air flows on the inner side of the filter element at the moment, namely the actual pressure difference between the inner side and the outer side of the filter element is very large and is close to the critical value of the pressure difference; if the filter screen of filter core takes place the condition of jam because of the dust is too much, the air that the air outside the filter core got into the filter core inboard through the filter core is less, and the air flow of filter core inboard this moment is more gentle, and the actual pressure differential of the inside and outside both sides of filter core is great promptly, but is less than the pressure differential critical value. In the same way, the fault condition of filter core is different, and is also different to the influence of the actual wind speed of air conditioner air-out pipeline department, and wherein, great actual pressure difference corresponds less actual wind speed, but the actual wind speed of air conditioner air-out pipeline department receives the valve of pipeline, the angle and the direction of flabellum to and a plurality of factors influence such as filter core, and then, regard the actual wind speed of air conditioner air-out pipeline department as the abnormal conditions of auxiliary parameter monitoring filter core. After the filter element is operated for a long time, the filter element may break down due to the influence factors such as self material deformation, and the filter element may lose the filtering effect due to the blocking condition caused by the long-term use of the filter screen, and then, a service time threshold value needs to be set for the service time of the filter element.
In the embodiment of the application, the actual pressure difference between the inner side and the outer side of the filter element is determined in real time through the following steps:
acquiring a first actual pressure value on the inner side and a second actual pressure value on the outer side of the filter element in real time;
and determining the actual pressure difference between the inner side and the outer side of the filter element based on the first actual pressure value and the second actual pressure value.
Specifically, by calculating a difference between a first actual pressure value inside the filter element and a second actual pressure value outside the filter element, an actual pressure difference between the inside and the outside of the filter element can be obtained.
And S120, if the actual pressure difference is detected to be larger than the first pressure difference threshold value, the actual wind speed is smaller than the first wind speed threshold value, and the actual service time is larger than the service time threshold value, determining that the monitoring result of the filter element is abnormal.
In the embodiment of the present application, three parameters that affect the abnormal condition of the filter element need to be determined simultaneously: the actual pressure difference, the actual wind speed and the actual service time are compared and analyzed with a first pressure difference threshold value, a first wind speed threshold value and a service time threshold value which are preset by the air conditioning system respectively, when the three parameters meet the setting requirements simultaneously, the filter element can be determined to be abnormal, and at the moment, the reason for causing the abnormality of the filter element is the blockage caused by the fact that the filter element is too long in service time and the accumulated dust is too much. Furthermore, the method for monitoring the abnormal condition of the filter element has the advantages that the number of unstable factors is small, the limitation and uncertainty of manual observation are avoided, the analysis result is accurate, and the replacement or maintenance of the air conditioner filter element can be timely reminded.
And S130, sending the monitoring result of the filter element to an equipment terminal, and displaying the monitoring result of the filter element by a touch screen of the equipment terminal.
In the embodiment of the application, when the air conditioning system monitors that the filter element is abnormal, the abnormal result of the filter element can be sent to the equipment terminal, and the abnormal result can be displayed on the touch screen by the equipment terminal, so that an operator is prompted to replace the filter element in time.
Specifically, this application embodiment adopts the touch-sensitive screen, cancels button air conditioner panel, and the reaction sensitivity of touch-sensitive screen is fine, can use any object touch, and stability can be better, and the setting can adapt to there being the adverse circumstances of dust and steam, has solved button control panel fault rate height, controls inconvenient problem, and all operations and control on the air conditioning system are all integrated through the controller, carry out all operation control and fault information feedback on the touch-sensitive screen.
The monitoring method of the air conditioner filter element provided by the embodiment of the application monitors whether the filter element is abnormal in the working process according to three parameters, namely the actual pressure difference between the inner side and the outer side of the filter element, the actual air speed at the air conditioner air outlet pipeline and the actual service time of the filter element, compares the three parameters with a preset first pressure difference threshold value between the inner side and the outer side of the filter element, a first air speed threshold value at the air conditioner air outlet pipeline and a service time threshold value of the filter element respectively, analyzes whether the filter element has an abnormal problem, if the filter element has the abnormal problem, a monitoring result of the abnormal filter element is displayed on a touch screen of an equipment terminal, avoids the problem that the abnormal filter element is replaced completely depending on the visual inspection and experience of workers after sale of an excavator in the prior art, the error is easily caused by more unstable factors, and the problems of time and labor are wasted, and the application enables an operator to accurately receive feedback information of the abnormal filter element, and the filter element is replaced in time, so that time and labor are saved, and the air quality in the cab of the excavator can be ensured.
Preferably, before S130, the monitoring method further includes:
acquiring a preset second pressure difference threshold value between the inner side and the outer side of the filter element and a second air speed threshold value at an air outlet pipeline of the air conditioner, wherein the second pressure difference threshold value is smaller than the first pressure difference threshold value, and the second air speed threshold value is larger than the first air speed threshold value;
and if the actual pressure difference is not larger than the second pressure difference threshold value and the actual wind speed is not smaller than the second wind speed threshold value, determining that the monitoring result of the filter element is abnormal.
In the embodiment of the present application, the second pressure difference threshold and the second wind speed threshold are mainly set for monitoring when the filter element has a leak opening, there is no problem of any shielding failure, or forgets to install the filter element due to negligence of work, when these situations occur, the air does not pass through the filter element to be filtered and directly enters the inside of the filter element from the outside of the filter element, at this time, the air flow inside the filter element is basically the same as the air flow outside the filter element, namely, the actual pressure difference between the inside and the outside of the filter element is very small, close to 0, and the actual wind speed is very large.
In order to monitor the abnormal conditions of the filter element caused by the leakage opening or the non-installation, a preset second pressure difference threshold value needs to be set to be small, and the second pressure difference threshold value is smaller than the first pressure difference threshold value; similarly, the preset second wind speed threshold is set to be large, and the second wind speed threshold is larger than the first wind speed threshold.
Preferably, before S130, the monitoring method further includes:
acquiring a preset third pressure difference threshold value between the inner side and the outer side of the filter element and a third air speed threshold value at an air outlet pipeline of the air conditioner, wherein the third pressure difference threshold value is greater than the first pressure difference threshold value, and the third air speed threshold value is smaller than the first air speed threshold value;
and if the actual pressure difference is not smaller than the third pressure difference threshold value and the actual wind speed is not larger than the third wind speed threshold value, determining that the monitoring result of the filter element is abnormal.
In the embodiment of the present application, the third pressure difference threshold and the third wind speed threshold are set to mainly monitor the problem of failure caused by the situation that the filter screen material of the filter element is deformed and the like and is close to complete blockage, when the situation occurs, air outside the filter element cannot enter the inner side of the filter element through the filter element, and at this time, no air flows inside the filter element basically, that is, the actual pressure difference between the inner side and the outer side of the filter element is very large and is close to the pressure difference critical value, and the actual wind speed is very small or even 0.
In order to monitor the abnormal condition that the filter screen of the filter element is nearly completely blocked due to failure, a preset third pressure difference threshold value needs to be set to be large, and the third pressure difference threshold value is larger than the first pressure difference threshold value; similarly, the preset third wind speed threshold is set to be very small, and the third wind speed threshold is smaller than the first wind speed threshold.
In summary, the causes of the filter element abnormality include three cases; the first is that the filter screen of the filter element is blocked due to excessive dust, and the filter element abnormality caused by normal reasons is judged by a first pressure difference threshold value, a first wind speed threshold value and a service time threshold value; secondly, the filter element is in a leak opening fault or is in an abnormal condition of being forgotten to be installed, and the abnormal condition caused by the over-ventilation fault is judged by a second pressure difference threshold value and a second wind speed threshold value; and the third is the abnormity of the filter screen of the filter element which is close to the complete blockage fault caused by the material of the filter element, and the abnormity caused by the fault of excessive unvented air is judged by a third pressure difference threshold value and a third air speed threshold value. Through the setting of three sets of thresholds, the unusual condition of detection filter core that can be accurate reduces the consumption of manpower and materials, reduces and uses and the maintenance cost.
Preferably, the monitoring method further comprises:
if it is detected that the actual pressure difference is not greater than the first pressure difference threshold and the actual pressure difference is not less than the second pressure difference threshold,
and if the actual wind speed is not less than the first wind speed threshold value and the actual wind speed is not greater than the second wind speed threshold value, determining that the monitoring result of the filter element is normal.
In the embodiment of the application, only the actual pressure difference and the actual wind speed need to be referred to determine that the monitoring result of the filter element is a normal factor. In actual use, the condition that the air conditioning system is not used after the filter element is installed exists, so that the service time of the filter element possibly exceeds a service time threshold value, but the working condition of the filter element is still normal, namely the actual pressure difference and the actual wind speed meet the requirements, the filter element does not need to be replaced under the condition, and the monitoring result of the filter element is displayed to be normal.
Specifically, when the filter element satisfies: and when the actual pressure difference is between the second pressure difference threshold and the first pressure difference threshold and the actual wind speed is between the first wind speed threshold and the second wind speed threshold, determining that the working state of the filter element is normal, and accordingly determining that the monitoring result of the filter element is normal.
Preferably, after S130, the monitoring method further comprises:
and sending the monitoring result of the filter element to an alarm module, and enabling the alarm module to alarm according to the monitoring result.
Specifically, only the abnormal monitoring result of the filter element is sent to the alarm module, so that the alarm module gives an alarm according to the abnormal monitoring result of the filter element, and further reminds an operator to replace the filter element, wherein the normal monitoring result of the filter element is not sent to the alarm module, so that the alarm module does not give an alarm to the normal monitoring result of the filter element.
