Abstract

A warehouse system and method for detecting air particles in a warehouse are disclosed. The warehouse system includes storage locations, air filters, a cartridge, and a control base. The air filters are correspondingly arranged on outer sides of each storage location. A detecting module of the cartridge detects the air particles on a surface of corresponding air filter of the abnormal storage locations. The detecting module further calculates a radius of the air particles and transmits the radius of the air particles to the control base. The control base determines if the corresponding air filter of the abnormal storage locations has leaked. The detecting process of the claimed invention is safer, more precise and convenient.
