【摘要】 温湿度、光照强度和二氧化碳浓度是影响温室大棚作物生长的三大要素,为实时监控这3种关键要素以及大棚作物现场状况,提高大棚作物产量,提出一种基于web的温室大棚远程监测系统设计方案。介绍了系统总体设计方案及主要硬件,在基于ARM的嵌入式linux系统上移植开源软件BOA和Mjpg-streamer搭建web服务器和视频服务器、移植SQLite构建数据库并详细阐述了它们的移植过程。在此基础上设计CGI网关程序,通过接入Internet的任意一台远程PC机或智能手机的浏览器可实时监控棚内环境状况并发送控制命令,真正实现温室作物种植网络化管理。更多还原

【Abstract】 Temperature and humidity,light intensity and carbon dioxide concentration are three key factors to affect the greenhouse crop growth,for real-time monitoring the three key elements and greenhouse crops situation and increasing the greenhouse crop production,a kind of greenhouse remote monitoring system design scheme is put forward based on web. Introducing the overall design method of the system and the concerned main hardware,open source software BOA and Mjpg-streamer were transplanted to build web server and video server in the embedded linux based on ARM. SQLite database was also constructed. And the transplantation processes are elaborated in detail. The CGI gateway program was designed on this basis. By introduceing the CGI program design method,realtime monitoring the state of the greenhouse environment and sending control command through some remote PC or intelligent mobile phone browser accessed Internet,this system realize the networked management of greenhouse crops.更多还原
