基于RL-ARM的嵌入式温棚环境监控系统设计

Design of Monitoring System on Greenhouse Environment Based on RL-ARM

提出一种嵌入式温棚监控系统设计方案,应用于林木种苗培育温棚环境的自动调节。该设计以NXP2000系列微控制器芯片为硬件核心,在程序设计中充分利用了MDK开发套件中RL-ARM实时库提供的RTX操作系统、文件系统和TCP/IP协议栈。本文设计的监控系统通过485总线收集监测数据,同时作为Web服务器,不但将监测数据通过网页发送给客户端,并且利用CGI技术将客户端在页面上操作的控制信息传送给服务器,实现远程监控。

Designing of embedded greenhouse control system is discussed in this paper.NXP2000 MCU is used as the core ot hardware platform.In the process of program designing,RL-ARM Real Time Library provided by MDK-ARM is introduced.The control system discussed in this article get information through 485 BUS,the system also act as WEB server provide environment parameter to client through Ethernet,in the further way the control message that the client operate on web page can be processed and reacted by the way of CGI technology.
