基于RS-485总线的温室环境控制系统研制

Developing the control system of greenhouse environments based on RS-485BUS

作物生长需要一个适宜的环境,在可控环境下,可以不分季节、不分地区地种植所需的作物。控制系统为实现这一目标提供了基础。控制系统设计采用主从模式,基于RS-485总线协议,设计全数字化传感器和测控输入输出模块;采用COM组件技术设计应用软件的数据采集、控制算法和控制输出组件。整个系统经过测试和运行,证明满足可控环境调控要求。

The crop growth requires a favorable environment.Crops can be grown at different districts,and different seasons in controlled environments.In order to realize this goal,a new control system based on RS-485bus is designed in the light of the master/slave mode.The design method of intelligent sensors and I/O modules is given,and the program methodology using COM component techniques is described in developing applica-tion software with data collection,control algorithm and control output modules.The system passes testing and the operation shows designed control system can be true of controlled environ-ments.
