Dust collection equipment, method and apparatus for handling air duct exception of dust collection equipment

A method for handling an air duct abnormality of dust collection equipment, comprising:

• receiving an air pressure value detected by an air pressure sensor, wherein the air pressure sensor is located in an air path between a blower and a dust filter of the dust collection equipment;
• determining whether an abnormal event occurs in an air duct of the dust collection equipment according to the air pressure value detected in real time;
• and
• performing corresponding handling according to the type of the abnormal event, in response to determining that the abnormal event occurs, and
• wherein determining whether the abnormal event occurs the air duct of the dust collection equipment according to the air pressure value detected in real time further comprises:
• determining that an abnormal event in which the air duct is blocked occurs, in response to determining that the air pressure value detected in real time drops to be equal to or less than a set blockage air pressure threshold from normal operating air pressure within a first duration;
• determining that an abnormal event in which collected dust is excessive occurs, in response to determining that the air pressure value detected in real time gradually drops to be equal to or less than a set dumping air pressure threshold, and continuously and gradually drops within a second duration;
• and
• determining that an abnormal event in which the dust filter is excessively dirty occurs, in response to determining that the air pressure value detected in real time drops to be equal to or less than a set excessively dirty air pressure threshold, and keeps stable within a third duration.
