摘要
根据工厂化农业的要求 ,研制了温室环境微机测控系统 .系统由一台主控机和分布于现场的多台测控机组成 ,通过 RS- 42 2 A串行总线方式连接 .测控机由 89C5 2单片机控制 ,使用多个传感器测量温室中的温度、湿度、光照度、CO2 浓度等环境参数 .主控机完成数据的采集存储显示、数据库维护和专家决策控制 .系统具有结构简单、可靠性高、扩展性能好。
Based on the requirement of industrialized efficient agriculture, a microcomputer measuring controlling system was developed The system consists of a master controller and some measuring controlling instruments, which located in greenhouse, and they are connected with RS 422A serial bus The instrument, which controlled by 89C52 single chip microcomputer, measures the environmental parameters of greenhouse, such as temperature, humidity, light intensity and CO 2 density The master controller realizes data communication, save, display, database operation and expert decision making The system is distinguished by its simple structure, high reliability, easy expansibility and good performance of anti interference
