基于ARM的农业温室多点温度采集系统的设计

温室技术是我国实现农业信息化过程的重要环节,温度是温室控制中的重要环境参数.传统的单片机控制已经不能满足现代温室高精度、快速采集及响应的要求.建立了基于32位ARM架构的微处理器和uClinux操作系统的试验平台,分析了软硬件的构成,并通过Rt18019AS网卡接人Internet,具有实时性、多任务、多线程以及友好的人机界面的功能.结合实际温室进行了一系列试验,对采集数据进行了分析,提出了一些可扩展型、创新型的方案,这对于温室的智能化控制是非常有实际意义的.

Design of the Greenhouse''''s Multi-point Temperature Gathering Based on ARM

Greenhouse technology is the important part of agriculture information process, temperature is the main environmental parameter of it. Conventional singlechip control has been not meet the requires of the high-precision, fast response speed and acquisition requirements of the modern agricultural. A experimentation platform based on the 32-bit structure microprocessor and the uClinux embedded operating system is built, its software and hardware are analyzed, and it is connected to internet by Rt18019AS network card , can satisfy real time quality, multi-task, multi-threading and friendly manmachine interface. A series of experiments are done for real greenhouse, according to the analysis of the gathered data, some extensible, innovative schemes are proposed, this is very significant for the intellectualized control of greenhouse.
