Abstract

The invention discloses a multi-target rice mill unit scheduling optimization system based on ACO-BP. A 4*4 rice milling unit control system is designed, multi-target processing can be achieved among units through scheduling optimization, processing parameters of each rice milling are optimized, a rice breaking rate of a rice mill can be reduced, and processing efficiency of the units can be improved. The unit control system optimizes an internal utilization algorithm of the units, can regulate and control the processing parameters of each rice milling according to a single processing target, realizes an online whitening precision intelligent control of the units and reduces a operation cost of the rice mill. The rice milling unit control system is built in a manner of optimizing a BP neural network by using an ant colony optimization algorithm (ACO), the ant colony optimization algorithm can accelerate a learning rate of a neural network, convergence to optimal parameters is faster, and a neural network model for optimally regulating and controlling the rice milling units is built. A built rice milling unit database can perform iterative optimization on processing parameters and processing schemes through evaluation of products and learning ability of the neural network, and self-learning of the database is realized.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to an ACO-BP-based multi-objective scheduling optimization system for rice milling units. Background technique [0002] In recent years, the automation of production equipment in the rice processing industry has developed rapidly. Among them, the rice milling equipment now has a single rice milling machine control system, which is often monitored by monitoring the roller shaft speed of a single rice machine and the temperature rise of the whitening room temperature. Use PID control or fuzzy control and other adjustment methods to control the flow rate of the feed port or the speed of the spindle motor. At present, the processing function of the rice milling unit is simple, the control system regulates the processing efficiency of a single rice milling machine is low, the production energy consumption of the unit is high, and the quality of polished rice varies after processi...
