国内温室环境在线控制系统的研究进展

Research Progress of On-line Control System in Domestic Greenhouse Environment

综述了温室在线控制系统的研究现状,按照温室在线控制系统的控制方法,将系统分为基于单片机控制、基于PLC控制、基于网络技术控制、基于工控技术控制(IPC)和基于总线技术控制等几类。目前,温室在线控制主要还是采用分段式控制和人工设定相结合的方法。未来温室在线环境控制的研究重点是控制系统的智能化和信号传输的无线化,通过综合考虑环境因子、作物生长及经济性等因素,来获得适合作物最佳生长条件的智能决策支持及控制系统。这将是未来温室在线控制系统的发展方向,能够达到改善作物品质和提高经济效益的目的。

Overview of the present situation of on-line control system in greenhouse, according to the control method of on-line control system, greenhouse is divided into based on single-chip microcomputer（SCM） control, based on PLC control, based on network control, based on industrial PC （IPC） and based on bus technology control. Currently, on- line control in greenhouse mainly uses the segmented control and manually set method. In the future, on-line control in greenhouse is smart and wireless control system. Through integrated consider environment factor, crop growth and the economic sexual factors to obtained best growth conditions for crop, the smart decision-making support and the control system is the development direction of on-line control system in greenhouse, thus reached the purposes of improve crop quality and improve economic benefits.
