AI Technical Summary
Technical Problem
Existing technology cannot accurately monitor the usage status of air filters in real time, resulting in users being unable to repair or replace filter elements in a timely manner.
Method used
By acquiring the actual intake resistance and flow rate of the engine intake system in real time, combined with the pre-calibrated dust content, the amount of ash added is calculated using the integral method, and compared with the theoretical relationship curve to determine the state of the air filter.
Benefits of technology
It enables accurate real-time monitoring of air filters, timely warning of abnormal conditions, improves service life and reduces maintenance costs.

Abstract
本公开提供了一种状态检测方法、控制器、系统、设备和存储介质。该方法包括：实时地获取发动机进气系统的实际进气阻力值和发动机的实际进气流量；根据实际进气流量和预先标定的灰尘含量，在工作时间段内进行积分，得到当前时刻的实际加灰量，实际加灰量与当前时刻的实际进气阻力值对应；根据实际加灰量、在发动机最低转速下进气阻力值与加灰量的理论关系曲线和在发动机最高转速下进气阻力值与加灰量的理论关系曲线，获得在发动机最低转速下的第一理论进气阻力值和在发动机最高转速下的第二理论进气阻力值；和根据当前时刻的实际进气阻力值、第一理论进气阻力值和第二理论进气阻力值确定空气滤清器的状态。
