教学型温室大棚电源系统的研制

摘要

In this paper, a greenhouse power supply system was developed which can not only meet the needs of experimental teaching for undergraduates in mechanical and electrical integration, but also the needs of scientific research for postgraduates. The unique power supply system can convert the original 220 V AC single-phase electricity into stabile 5 V, 12 V, 24 V. Meanwhile, it can give the control flow chart of the SCM system according to the request of the control system so that it can meet the requirement of the greenhouse control system for teaching.%研制了一套既能满足农机专业本科生机电一体化的课程实验教学,又能满足部分研究生科研工作需要的教学型温室大棚.该温室大棚不仅能模拟出真实的外界环境变化,还能通过传感器及多套控制系统,采集模拟环境的变化对大棚的内部环境自动进行实时调节,达到农业生产的需求.特别针对单片机控制系统中,不同的传感器、执行机构对电源需求的不同,而专门设计了教学型温室大棚的电源供给系统,能够将原有的220 V AC单相电转变成5、12、24 V的稳定电压,提供给不同的设备使用,并进行供电系统功耗的要求计算.同时根据系统控制的要求给出单片机系统的控制流程图,使其能满足教学型温室大棚的控制系统需求.
