【摘要】 讨论了在温室控制中引入PLC技术构成分布式控制系统的方法,详细介绍了系统的特点、组成、软硬件设计、实时动态监控系统及通信问题。分布式的控制结构,使各子系统相对独立,管理与控制功能分开,易于实现群控化管理,提高了系统的可靠性,且易于扩展。系统成本低廉,性能稳定,通用性好,符合中国国情,具有广泛的应用前景。更多还原

【Abstract】 The method of distributed control system composed by PLC technology in glasshouse control is introduced in this paper. It gives a detailed introduction to the characteristics, constitutes, software and hardware design, real-time dynamic surveillance and communication of the system. The distributed control structure makes all sub-systems independent relatively, separates the management and control function, and easy to realize the swarm control management, greatly improves the reliability and expandable of the system. It has the chacacters of low cost, stable function, wide adoptability, etc, which matches the conditions of China and has charming application foreground.更多还原
