Automatic control method of cigarette throwing production flow

The invention provides an automatic control method for the production flow of cut tobacco of cigarettes, which comprises the steps as follows: an upper system packages the controlling parameters of the production process into controlling parameter packages according to the batches, and issues the controlling parameter packages to production line segment control levels; the production line segmentcontrol levels control the control units of the production line segment control levels according to the set controlling parameters of the controlling parameter packages, thus completing the productive tasks of the corresponding batches in turn; during the production process, the production line segment control levels temporarily save the synchronously produced batch data in temporary storage areas thereof, and transmit the batch data to the upper system on completion of the production of the batches. The cut tobacco production line control levels convert control orientation into management orientation by applying batch control to the production line control levels. Besides the automatic control function of the prior production process, the automatic control method further achieves the production management and process quality analysis statistical functions based on the batches.
