鲜切花温室多环境因子采集系统驱动的研究与开发

The Study and Development of Cut Flowers Greenhouse Multi-Environmental-Factors Acquisition System Driver

鲜切花温室环境因子例如CO2、光照度、温湿度、PH值、土壤盐分等对鲜切花生长有至关重要的影响,能够实时掌握温室中各种环境因子的情况并且根据环境的变化采取相应措施可以为鲜切花的生长提供最佳的环境,给花农创造更大的经济价值。本文在系统分析了相关研究的基础上,针对目前我国温室大棚环境因子采集多为单环境因子采集的现状,提出了以S3C2440为开发平台,以linux为操作系统,设计开发了多通道A/D转换驱动程序,对多路模拟信号进行转换,实现了鲜切花温室多环境因子的集成采集。

Cut flowers greenhouse environmental factors such as CO2,light intesty,temperature and humidity,PH value,soil salinity have a crucial impact on the growth of cut flowers,real-time controling of various environmental factors in greenhouse and according to the changing in the environment take the appropriate measures will provide the best growth environment for cut flowers,to create greater economic value for the growers.According to systematic analysis of the relevant research,based on the current greenhouse environment factor acquisition of China is much as a single environment factor acquisition,the paper took the S3C2440 as development platform and took linux as operating system,designed and developed a multi-channels A/D convertion driver,to achieve a conversion for multi channels analog signals,realized multi-environment-factors integrated acquisition for cut flowers greenhouse.
