中文摘要:以PID算法和模糊控制理论相结合的分段控制理论为控制策略,嵌入温室作物生长模型和栽培专家知识,基于RS485总线,设计了一个分布式温室智能测控系统,对温室生产环境因子进行实时监测、分析、智能决策输出,调节温室控制设备,创造最佳的温室作物生长环境条件。实践证明,分段控制算法使控制输出准确跟踪设置值。
Key Words:
Abstract:An intelligent platform based on RS485 bus was created. It takes the sectional-control theory which combines the PID algorithm with fuzzy control theory as the strategy and integrates the crop growth and cultivation expert system. The system real-timely measures the environment factors in greenhouse and analyzes them to make decision and control the output devices so as to create the optimal grow environmental conditions in greenhouse. The application shows that the sectional-control algorithm makes the output trace the set value correctly and the distributed and unit module structure make the maintenance easier and lower the running cost.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
