ARM-Linux嵌入式系统在农业大棚中的应用

温度、湿度和二氧化碳浓度是影响棚栽农作物生长的3大要素。为了实现农业大棚中这3种要素数据的远程实时采集,引入了当前嵌入式应用中较为成熟的ARM9微处理器和Linux嵌入式操作系统技术,采用温度传感器PH100TMPA、湿度传感器HM1500和二氧化碳浓度传感器NAP-21A,设计一种基于TCP/IP协议的嵌入式远程实时数据采集系统方案。从硬件设计和软件实现2方面对该系统进行具体阐述。在实际应用中,该系统运行稳定、可靠。

Design of Environmental Monitoring and Control System for Large-scale Pig House with Fermentation Bed

The design and assembly of environmental monitoring and control system for large-scale pig house with fermentation bed helped to solve the problem of environmental automatic control in piggery.The sensors would monitor the temperature,humidity,light,wind direction,wind speed,CO2,NH3and other parameters.On-line real-time data collection was achieved.The expert system was constructed to control the temperature in piggery below 30℃,to control the air and mattress humidities higher than 65%.Under the conditions of different season or different wind speed,even in day and night,the control actuators were different.The actuators included fanning wet curtain,lighting,micro spraying,spraying,propeller fan,electric aluminum alloy shutter and spraying systems on the roof.The actuators were integrated,and they control the piggery environment simultaneously.The system also designed the remote video monitor interface,parameter-monitoring curved interface and operation interface,which provided a good man-machine interface.
