Abstract

In order to solve the technical problem that in the prior art, a use condition or a state of a filter element cannot be accurately and timely determined, the invention provides a method, a device anda system for determining a state of a vehicle air conditioner filter element. The method for determining the state of the vehicle air conditioner filter element comprises the steps that a PM2.5 detection value of an air inlet of an air conditioner is acquired; whether the PM2.5 detection value of the air inlet of the air conditioner is greater than a preset concentration value or not is judged; when the PM2.5 detection value of the air inlet of the air conditioner is larger than the preset concentration value, a current filtering efficiency of the filter element is acquired; a current air volume value of an air blower is acquired; and according to the current air volume value of the air blower, the current filtering efficiency of the filter element and a preset calibration relation, current state information of the filter element is determined, and the preset calibration relation is used for representing a corresponding relation among the air volume value of the air blower, the filtering efficiency of the filter element and the state of the filter element. According to the method, the device and the system, the state of the filter element is directly determined according to the real-time air volume value of the air blower and the real-time filtering efficiency of the filter element in combination with the preset calibration relation, and the use condition of the filter elementis more accurately reflected in real time.

Description

technical field [0001] The invention relates to the technical field of filter element detection, in particular to a method, device and system for determining the state of a vehicle air-conditioning filter element. Background technique [0002] With the development of society, more and more vehicles have entered thousands of households, and vehicles have gradually become a necessity of life. With the improvement of people's living standards, people's requirements for the safety and comfort of vehicles are getting higher and higher, and vehicles have gradually become the second home that accompanies people's lives. [0003] The car's air conditioning filter element is used to filter the air inhaled by the car and has a filtering effect. It can effectively filter and absorb pollen, dust, peculiar smell, etc., so as to ensure good air in the car. However, the air conditioning filter itself has a certain dust holding capacity and absorption limit. While filtering these substanc...
