基于RS-485通信网络的分布式测控结构在温室群集散控制系统中的应用

Application of DCS based on RS-485 bus in control greenhouses

简要概述了分布式测控系统的基本结构,其具有很强的通用性和实用性。结合温室群环境集散控制系统的应用实例,介绍了采用RS-485构成的总线型温室环境分布式测控系统,利用主控计算机和多个单片机的主从通信方式实现了对多个温室环境的集散控制和采样信息的集中管理。

This paper summarizes the basic frame of the distributed control system,which has some practicability. A distributed control system in agriculture greenhouse based on RS485 bus is mainly introduced. Using the serial communications of the computer and single-chip micropressors , it can integratedly control and manage greenhouses.
