Abstract

The invention relates to a method for detecting failure of a static pressure difference of a dust-collection filter screen based on temperature correction. The method comprises the following steps: establishing a dust-collection filter screen failure detection experiment system, namely arranging a static pressure difference collection module upper computer of the dust-collection filter screen and a fault warning device in a purifier system; establishing a data collecting and recording system; enabling an air purifier to continuously work in an experiment environment, simultaneously monitoring the static pressure difference P(k) of the dust-collection filter screen of an air purifier system and an environment temperature T(k) in real time by virtue of the upper computer, and recording the total operational duration of the air purifier, wherein k represents a current operation moment. By utilizing the method based on the temperature correction, the change of the temperature correction of a same base temperature reference value can be estimated on line, so that the online fault diagnosis of the dust-collection filter screen of the air purifier system is realized. Finally, the method is applied to the failure detection of the dust-collection filter screen of the subsequent relevant air purifier system, and a correction method is finished in a programming manner, so that the hardware cost of the product is lowered, and the flexibility, reliability and accuracy of the system are improved.

Description

technical field

[0001] The invention relates to a fault diagnosis technology, in particular to a temperature correction-based method for detecting the static pressure difference of the failure of a dust collection filter. Background technique

[0002] In recent decades, with the development of industry and the provision of personal living standards, people have paid more and more attention to air quality. However, the statistical results in 2012 show that only 40.9% of the 325 prefecture-level and above cities meet the environmental air quality standards; only 23.9% of the 113 key environmental protection cities meet the environmental air quality standards. For improving air quality, people have proposed many effective methods and measures. Among them, air purifiers are the most commonly used and most effective tools for improving indoor air quality that is most closely related to people's lives.
