摘　　要：随着农业发展,温室控制的自动化越来越重要。温室中的各个监控区域距离在几十到上千米之间,它们与温室操作人员距离较远,传统的独立控制往往不方便。为了便于控制和数据管理,需要建立分布式温室控制系统进行集中测控。本系统选用合适的传感器和单片机进行环境采集,并通过搭建RS-485总线来连接各个采集点与用户PC端,实现对多个温室环境的采集,然后将数据上传到用户PC客户端。实验结果表明,PC客户端可以方便高效地对多个网络节点的温室进行综合测控。Modem greenhouse usually adopts distributed detection and control system. And the distance between two monitoring areas is ranging from a few tens of meters to several kilometers. These greenhouses are far away from greenhouse operators. For this system, collection points and user sides are connected by RS-485 bus. Thus, the greenhouse environment is collected by multiple collection points and the related data is uploaded to the PC side of users. In addition, in case of abnormal environment parameters, text-message alerts will be sent.
