Fuzzy Control Of Green Food Preservation

With the continuous development of the microprocessor technology and industry aLltomatiofl level, the microprocessor fuzzy-control technology has been widely sprcaded and applied. This control technology was based on fuzzy-control theory and provided a kind of fire-new and efficial control method in application of industry control, household appliances and instrument intelligence, it has prodigious practical use and prospect.This paper is aimed at the task of the fresh-preserved and long-termed storage, transportation of vegetable and fruits in foods industry, a kind of device, the gas-adjusted ficsh-preserved biii was put forward. In this paper we applied fuzzy-control theory to realize auto-control to temperature, humidity and oxygen composition o the bin, then we utilitied genetic algorithm to optimized the fuzzy-control rules. We complislied finally the software and hardware design of the whole control system.In the first chapter, the paper introduced simply the gas-adjusted fresh-preserved bin auto-control system, the control parameters are determined and the microprocessor fuzzy-control project was plan out. In the second chapter, the paper applied fuzzy coiitrol theory, the fuzzy controller for temperature, humidity and oxygen composition were designed realized. In the third chapter, the paper introduced the basic principle and realization of genetic algorithm, then optimized the fuzzy-control rules. In the fourth chapter, the paper introduced the realization of software and hardware design for fuzzy-controller with microprocessor. Fiiially, several pieces of?suggestions were put to improve the whole system.
