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。

Abstract: 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-485 bus 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 application 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 environments.
Key words: field bus , distributed system, COM component, controlled environment, intelligent node
