Control system and method for automatically changing storage cabinets in cigarette factory

The invention discloses a control system and method for automatically changing storage cabinets in a cigarette factory, and the method comprises the steps: receiving the real-time data of an electronic scale, a full cabinet detection photoelectric sensor and an empty cabinet detection photoelectric sensor of each storage cabinet, calculating and comparing the rated loadable material weight of the storage cabinet with the actual loading material weight in the storage cabinet, and meanwhile, carrying out the automatic replacement of the storage cabinets. Based on a full cabinet detection photoelectric sensor and an empty cabinet detection photoelectric sensor, whether the storage cabinet is empty or full is obtained; when the two sensors are still shielded after detecting shielding and meeting a delay condition, and the actual loading material weight in the storage cabinet is greater than the rated loadable material weight of the storage cabinet, determining that the current storage cabinet is full of materials
