摘要
针对目前温室面积不断增大、温室内传感器种类及数量不断增多等情况,利用虚拟仪器软件开发平台LabVIEW,设计出PID温室远程智能控制系统。此系统由温室内各类传感器得到非电量转化为随环境参数改变的电量,然后用虚拟仪器对输入到数据采集卡的电信号进行实时采集,实现对温室环境参数数据远程显示、存储、统计、控制等。通过控制不同时期作物生长所需要的最佳环境参数,实现了温室的智能化管理。
In the case of the kind and number of transducers are increasing along with the area of the greenhouse increasing, Apply virtual instrument Labview to design greenhouse long-distance PID intelligent controlling system.The system will Translate non electrical quantity gained by transducers into electrical quantity varied by the environmental parameter, the electrical signal gained by the data acquisition board are acquired real-time by virtual instrument some functions are realized such as display, storage, statistic and control for the environmental parameter. The greenhouse is managed intelligently by controlling optimum environment parameter that different time crop is needed.
