Problems solved by technology

The color of the eye filter is subjective, there is no uniform standard for operation, and it is very inconvenient
It is more scientific to replace the filter according to the status of the reminder light. At present, it is mainly to remind the user to replace the filter in time through the use time of the car air-conditioning filter or the mileage of the vehicle. Because the temperature, humidity, air quality, and sandstorms in different regions vary greatly, so The method of judging the life of the car air-conditioning filter based on the use time or mileage is inaccurate; in addition, in household or commercial air purifiers, there are also methods of judging the filter by checking the pressure difference, wind speed, PM2.5 concentration, etc. before and after the filter service life, and this requires the use of multiple sensors, multiple sensors are not only costly, but also take up a lot of space, and the application market is small

Embodiment 1

[0092] figure 1 It is a flow chart of a method for detecting the service life of an automobile air-conditioning filter provided by an embodiment of the present invention. Such as figure 1 As shown, the method includes the following steps:

[0093] S1: Collect the PM2.5 concentration value of the air inside the car, the PM2.5 concentration value of the air outside the car and the current speed of the vehicle. Calculate the real-time PM2.5 concentration value;

[0094] S2: Determine whether the fan control mode is internal circulation mode;

[0095] S3: If the fan control mode is the internal circulation mode, obtain the current real-time fan application voltage, and calculate the influence of the fan application voltage on the life of the filter according to the real-time fan application voltage, the preset minimum fan application voltage and the maximum fan application voltage. a weight;

[0096] S4: If the fan control mode is not the internal circulation mode, switch the...

Embodiment 2

[0131] An embodiment of the present invention provides a detection device for the service life of an automobile air-conditioning filter, please refer to figure 2 , the device includes:

[0132] Acquisition form 10 is used to collect the PM2.5 concentration value of the air inside the car, the PM2.5 concentration value of the air outside the car and the current speed of the vehicle. and the current vehicle speed to calculate the real-time PM2.5 concentration value;

[0133] Mode judging unit 20, used to judge whether the fan control mode is internal circulation mode;

[0134] The first calculation unit 30 is used to obtain the current real-time fan application voltage when it is determined that the fan control mode is the internal circulation mode, and calculate the fan application voltage according to the real-time fan application voltage, the preset minimum fan application voltage and the highest fan application voltage. The first weight of the impact of voltage on filter ...

Embodiment 3

[0170] This embodiment provides an embodiment of a detection scheme for the service life of an automobile air-conditioning filter. The solution mainly includes the PM2.5 calculation module and the filter life detection module. The specific design ideas of each module are as follows.

[0171] 1PM2.5 computing module design

[0172] Real-time PM2.5 calculation means that after reading the PM2.5 concentration value through the PM2.5 sensor in the purification system, the controller performs a comprehensive calculation based on the current controller mode and the internal and external environment of the vehicle.

[0173] The determination of the real-time PM2.5 concentration value directly affects the weighted calculation of the remaining life of the filter, and plays a very important role in the intelligent detection of life. In order to improve the accuracy of the final calculation of the remaining life of the filter, this program has formulated the following real-time PM2.5 co...

Abstract

The invention relates to filter screen life detection technology, in particular to a method and device for detecting the life span of an automobile air conditioner filter screen. The method includes: calculating the real-time PM2.5 concentration value according to the PM2.5 concentration value of the air inside the vehicle, the PM2.5 concentration value of the air outside the vehicle, and the current vehicle speed; judging whether the fan control mode is the internal circulation mode; if so, calculating The first weight of the influence of the fan application voltage on the life of the filter and the second weight of the influence of the PM2.5 concentration value on the life of the filter; the air-conditioning filter is calculated according to the preset service life of the air-conditioning filter, the first weight and the second weight Remaining service life: judging whether the remaining service life of the air conditioner filter is lower than the set limit value, and sending a reminder message to replace the air conditioner filter when the remaining service life is lower than the set limit value. The invention can accurately calculate the remaining service life of the automobile filter screen, and then can accurately remind customers to replace the filter screen.

Description

technical field [0001] The invention relates to filter screen life detection technology, in particular to a method and device for detecting the life span of an automobile air conditioner filter screen. Background technique [0002] With the deterioration of the environment, people pay more attention to the air quality in the car. More and more vehicles are equipped with HEPA filters to improve the air in the car. However, when the HEPA filter is approaching or reaching its service life, the purification effect will become worse, and it will even pollute the air in the car again. Therefore, users need to replace the HEPA filter in time before it reaches the end of its service life, so as to maintain good air quality in the car. [0003] The calculation of the filter life of the purifier is very data-based, which is meaningless for the current industry status where the new national standard has not yet been implemented, because you can rarely see the CCM certification inform...
