Embodiment Construction
[0024] In order to make the purpose, technical solutions and advantages of the examples of the present invention more clear, the technical solutions in the examples of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the examples of the present invention.
[0025] As one of the main components of the engine air intake system, the air filter mainly provides clean, dry and sufficient air for the engine. As one of the important components of the air filter, the filter element has a certain service life. After reaching the service life, it needs Replace the filter element in time. Especially for construction machinery vehicles, the working environment is relatively harsh, and the air quality is poor and there are many impurities, resulting in a large load on the air filter element, fast life decay, and the problem of untimely replacement of the filter element is prone to occur.

The monitoring method and system of the air filter provided by the present invention obtain the air quality parameters, and determine the total air filtration capacity corresponding to the air filter according to the air quality parameters; obtain the real-time intake air volume of the air filter, and perform real-time The air volume is time-cumulatively processed to obtain the used air filtration volume of the air filter; the remaining service life information of the air filter is determined according to the total air filtration volume and the used air filtration volume, and the remaining service life information is output; that is, this The embodiment of the invention determines the total air filtration capacity of the air filter under the current working environment by obtaining air quality parameters, and then time-accumulates the real-time intake air volume of the air filter to determine the used air filtration capacity of the air filter, and then according to the total air filtration capacity The remaining service life of the air filter is determined based on the amount of air filtered and the air filter has been used, so that the accurate prediction of the service life of the air filter is realized, and then the filter element can be replaced in time.
Description
technical field [0001] The invention relates to engine technology, in particular to a monitoring method and system for an air filter. Background technique [0002] As one of the main components of the engine air intake system, the air filter mainly provides clean, dry and sufficient air for the engine. As one of the important components of the air filter, the filter element has a certain service life. After reaching the service life, it needs Replace the filter element in time. [0003] In the prior art, technicians usually artificially predict the life of the filter element of the air filter according to the operating conditions, and then decide whether to replace the filter element. [0004] However, the accuracy of artificially predicting the service life of the filter element is low, and the problem of untimely or premature replacement of the filter element is likely to occur. Contents of the invention [0005] In view of the above problems, the present invention pro...
