In order to realize the intelligent management of large - scale greenhouse,a set of remote monitoring system based on GPRS network and RS485 bus is designed in this paper. The master controller and slave controller of the system are connected by RS485. The command image area and data area are divided in the internal storage with process image method to exchange data,and the field data are transmitted to the monitoring upper computer through GPRS network. Experimental results show that the system can achieve multi - area greenhouse remote monitoring,collecting field's information and releasing the suitable growth parameters of crops,which realized good real - time performance and stability,and it is of good economic and social benefits.%为实现温室大棚规模化智能化管理,该文设计了一套基于GPRS网络与RS485总线的温室大棚远程监控系统.系统的主从控制器通过485总线连接,采用过程映像的方法,在内部存储区中划分命令映像区和数据映像区进行数据交换,数据通过GPRS网络传输至监控上位机.实验表明,该系统能实现多区域温室大棚的远程监控,采集现场信息,发布作物最优的生长参数,实时性和稳定性良好,具有潜在的经济效益和社会效益.
