Case reasoning technology-based damping machine intelligent optimized control method

Abstract

The invention relates to a case reasoning technology-based damping machine intelligent optimized control method, which is characterized in that: a moisture detection instrument is added to an inlet of a damping machine and is used for detecting the moisture content of tobacco leaves at the inlet of the damping machine; a water charging coefficient is selected as a direct operating variable, watercharging flow rate sprayed out by a steam-water combined nozzle in the damping machine is used as an indirect operation variable, and the moisture content of tobacco leaves at an outlet of the damping machine is used as a controlled variable; whether the current production stage is a beginning stage, a normal production stage or an ending stage is judged according to tobacco leaves instantaneous flow rate, tobacco leaves accumulated flow rate and charging time information; the water charging coefficient is preset according to the production stage and the tobacco leaves production technical condition information to obtain a water charging coefficient preset value; a feedback compensation rule database is built according to the production technical requirement and an operating mode; and thewater charging coefficient preset value is compensated in a feedback way according to the feedback compensation rule database to obtain an optimized water charging coefficient setup value. The methodovercomes the control difficulties such as tobacco leaves loosening damping process nonlinearity and large time delay.

Description

technical field [0001] The invention relates to a control method of tobacco production equipment, in particular to an intelligent optimal control method of a moisture regainer based on case reasoning technology. Background technique [0002] Moisturizing machine is one of the key equipments in the silk production line in the cigarette production process. It undertakes the task of increasing the moisture content and temperature of the tobacco sheet and improving the processing resistance of the tobacco sheet. Effectively controlling the moisture content and temperature of the tobacco sheets at the outlet of the moisture conditioner plays an extremely important role in the quality of the silk making effect. [0003] The working principle of the dampening machine is as follows: figure 1 shown. After the low-temperature and relatively dry tobacco is removed from the packing box, the cigarette stack is cut into several pieces with approximately equal thickness and weight, which...

Problems solved by technology

[0009] Aiming at the deficiencies in the prior art that the moisture content of the tobacco leaves at the entrance of the humidifier is not detected, the labor intensity of the operation is high, and the control effect of the moisture content at the exit is difficult to meet the process requirements, the technical problem to be solved by the present invention is to provide a method to reduce the workload of the operator. Intelligent optimization control method of moisture regainer based on case reasoning technology, which makes the control effect of outlet moisture content better
