Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
along with the reduction of automobile air conditioner filter screen life, although automobile air conditioner's purification effect changes little, along with the dust on the filter screen increases gradually, leads to the air volume to reduce gradually for the purification speed of air in the car reduces. Specifically, referring to fig. 1, fig. 1 is a table comparing the classification efficiency, pressure drop and ash storage capacity of the automotive screen of the present invention at different dust holding stages. As can be seen from fig. 1, the higher the dust holding stage is, the smaller the ventilation amount of the automobile filter screen becomes, and the lower the purification speed of the air in the automobile is. Based on the method, the service life of the filter screen of the automobile air conditioner can be detected according to the quality change of the air in the automobile, namely the service life of the filter screen of the automobile air conditioner is calculated according to the time when the PM2.5 value of the air in the automobile reaches a stable state. The method for detecting the service life of the filter screen of the automobile air conditioner is explained in detail below.
As shown in FIG. 2, the method for detecting the service life of the automobile air conditioner filter screen comprises the following steps:
S110, acquiring a PM2.5 value of air in the vehicle in real time;
S120, obtaining the time for the PM2.5 value of the air in the vehicle to reach a stable state according to the PM2.5 value of the air in the vehicle;
And S130, calculating the service life of the automobile air conditioner filter screen according to the time when the PM2.5 value of the air in the automobile reaches a stable state.
In the above steps, the steps can be realized by a PM2.5 sensor and a processing unit provided in the vehicle. Specifically, in step S110, the PM2.5 value of the air in the vehicle is detected in real time by the PM2.5 sensor, and then the acquired PM2.5 value is transmitted to the processing unit in real time. Preferably, the sampling port of the PM2.5 sensor is arranged on the a-pillar on the passenger side (such as behind a horn cover on the a-pillar on the passenger side), and the detection module of the PM2.5 sensor is arranged on a sheet metal of the vehicle body below the a-pillar on the passenger side. Because the air inlet of the automobile air conditioner is mostly arranged below the front windshield, the PM2.5 sensor is arranged according to the above, on one hand, the sensor is close to the air inlet of the automobile air conditioner, and the change situation of the PM2.5 value in the automobile is easier to obtain; on the other hand, the utility model hardly occupies the space in the vehicle and does not affect the beauty in the vehicle.
in step S120, the processing unit obtains the time when the PM2.5 value of the air in the vehicle reaches the steady state according to the received PM2.5 value of the air in the vehicle. And in step S130, the processing unit calculates the service life of the automobile air conditioner filter screen according to the time when the PM2.5 value of the air in the automobile reaches the stable state.
it should be noted that the processing unit may take any suitable form, and may be, for example, a separate module, or a functional unit integrated into the hardware of the vehicle (e.g., an ECU of the vehicle, etc.). Preferably, the processing unit is connected with the PM2.5 sensor through a CAN bus, a mathematical model between the time when the PM2.5 value of the air in the automobile reaches the stable state and the service life of the automobile air conditioner filter screen is stored in the processing unit, and based on the mathematical model, the processing unit calculates the service life of the automobile air conditioner filter screen according to the time when the PM2.5 value of the air in the automobile reaches the stable state.
The method of establishing the mathematical model mentioned above will be described in detail below.
when the mathematical model is established, the automobile air conditioner filter screens in different dust holding stages are respectively used, and the time for the PM2.5 value of air in the automobile to reach a stable state is calculated under different windshields; and then establishing a mathematical model for the test result through Matlab. The stable state refers to a state in which when the air conditioner is used to purify the air in the vehicle, the air in the vehicle reaches a target PM2.5 value (at this time, the change of the PM2.5 value of the air in the vehicle is smaller than a preset value), that is, the air in the vehicle is in the stable state.
Specifically, a PM2.5 sensor for detecting the quality of air in the vehicle in real time is arranged in the vehicle. Preferably, the sampling port of the PM2.5 sensor is arranged on the a-pillar on the passenger side (for example, behind a horn cover on the a-pillar on the passenger side), and the detection module of the PM2.5 sensor is arranged on a sheet metal of the vehicle body below the a-pillar on the passenger side. After the vehicle is ignited to run, the value of the PM2.5 sensor can be read. Under the condition that the vehicle window is closed, the air inlet mode and the air outlet mode of the air conditioner are different, the use windshields are different, and the time for the concentration of PM2.5 to reach a relatively stable state is also different (the PM2.5 changes in a certain time and is smaller than a preset value, the state is regarded as a relatively stable state).
specifically, referring to fig. 3 and 4, fig. 3 is a time variation value of PM2.5 under different windshields of an automobile filter screen in the same dust holding stage; FIG. 4 is a graph of PM2.5 variation of an automobile filter screen in the same dust holding stage under different windshields. In this embodiment, a first damper, a second damper, a third damper and a fourth damper are used, respectively, and the fourth damper is larger than the third damper, the third damper is larger than the second damper, and the second damper is larger than the first damper. As can be seen from fig. 3 and 4, by using the car filter screen in the same dust holding stage, the variation value and the variation curve of the PM2.5 in the car with time are measured under different windscreens, and the time required for the PM2.5 to reach the equilibrium state is shorter as the windscreens are increased. And then, repeating the test by using automobile filter screens in different dust holding stages (for example, using filter screens in the dust holding stages of 0%, 10%, 20%, 30%, … and 100%), and selecting different gears (a first damper, a second damper, a third damper and a fourth damper) by switching the internal and external circulation modes of air inlet of the air conditioner, so as to measure the time when the PM2.5 values in the automobile reach a relatively stable state by using the filter screens in different dust holding stages respectively under different working conditions.
in this embodiment, an automobile filter screen with four dust containing stages is selected for testing, which are a first dust containing stage (0%), a second dust containing stage (25%), a third dust containing stage (50%) and a fourth dust containing stage (100%). Referring to fig. 5 and 6, fig. 5 is a time variation value of PM2.5 of an automobile filter screen at different dust holding stages under the same working condition; FIG. 6 is a graph showing the variation of PM2.5 of the automobile filter screen in different dust holding stages under the same working condition. Since different dust holding stages represent different dust amounts on the filter screen, it can be seen from fig. 5 and 6 that the more dust on the filter screen, the longer the PM2.5 value of the air in the vehicle reaches a relatively steady state. It should be noted that, because there are many data obtained in the test, the test data in one case is only exemplarily shown in this embodiment, and a person skilled in the art can obtain the time required for the filter screens at different dust holding stages to reach the stable state under different working conditions according to the test method described in this embodiment.
After the measurement is finished, a mathematical model can be established for the measurement result through Matlab, simulation is carried out, and an optimal algorithm is determined. Therefore, the time for the PM2.5 value of the filter screen at any dust holding stage to reach a stable state under different working conditions is obtained. Because different dust holding stages represent different dust amounts on the filter screen, the service life of the filter screen can be judged through the dust amount on the filter screen.
It should be noted that, in the above test stage, the position of the PM2.5 sensor and the position of the PM2.5 sensor during actual use are set at the same position, so that it can be ensured that the result of the test is consistent during actual use, and the final detection result is more accurate.
Furthermore, the processing unit can also display the calculated service life of the automobile air conditioner filter screen through the display screen, so that a user can visually see the remaining service life of the automobile filter screen. And when the service life of the automobile air conditioner filter screen is lower than a set limit value (for example, the service life of the filter screen is measured to be zero), a replacement prompt is sent.
In addition, as some vehicles may be left unused for a long time, bacteria may grow on the filter screen after the time exceeds a certain period, and air in the vehicle is polluted due to continuous use. Therefore, a time limit can be preset, even if the service life of the automobile filter screen obtained by using the detection method does not reach the replacement condition, when the service life of the automobile air conditioner filter screen reaches the preset time limit, a replacement prompt is sent. The preset time limit may be set according to the environment of the area where the vehicle is located.
In addition, the invention also provides a device for detecting the service life of the automobile air conditioner filter screen. The detection device includes a first PM2.5 sensor and a processing unit. The first PM2.5 sensor (namely the PM2.5 sensor) is used for acquiring a PM2.5 value of air in the vehicle in real time and sending the PM2.5 value of the air in the vehicle to the processing unit; the processing unit can obtain the time for the PM2.5 value of the air in the vehicle to reach a stable state according to the received PM2.5 value of the air in the vehicle; and the processing unit can also calculate the service life of the automobile air conditioner filter screen according to the time when the PM2.5 value of the air in the automobile reaches a stable state.
Referring to fig. 7, fig. 7 is a schematic structural diagram of a device for detecting the service life of a filter screen of an automobile air conditioner, wherein a processing unit is omitted for clarity. As shown in fig. 7, the sampling port 11 of the first PM2.5 sensor is provided on the a-pillar on the passenger side, and the detection module 30 of the first PM2.5 sensor is provided on the vehicle body sheet metal below the a-pillar on the passenger side.
As a preferred embodiment of the present invention, a second PM2.5 sensor is further provided in the vehicle, and the second PM2.5 sensor can acquire the PM2.5 value of the air inside the vehicle in real time and detect the PM2.5 value of the air outside the vehicle. As shown in fig. 7, the sampling port 21 of the second PM2.5 sensor may be led to the upper part of the water chute through a sheet metal hole, and is close to the external circulation air inlet, and the detection module 30 of the second PM2.5 sensor (in this embodiment, the first PM2.5 sensor and the second PM2.5 sensor share one detection module 30) is disposed on the sheet metal of the vehicle body below the a-pillar on the passenger side. Therefore, the service life of the automobile air conditioner filter screen can be monitored, the quality of the air outside the automobile can be acquired in real time, and the internal circulation mode and the external circulation mode of the air conditioner can be switched according to the quality of the air outside the automobile.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
