摘要
为了实现肥液自动供给的控制精度,设计了以P89C51为核心的肥液在线监测供给系统,通过对肥液酸度和电导率的测量,实现了供液系统的浓度在线自动监测和控制,使肥液灌溉系统的智能化水平大大提高。该控制系统具有体积小、安装方便以及运行可靠等特点,更有利于向水基质农业中推广应用。
In order to realize automatic precision of supplying monitor system,the system of on-line nutrient consistency supply can be designed based on P89C51 single-chip. It can realize automatic monitoring and control on-line through measuring acidity and conductivity ,so the intelligent level of nutrient supply can be increased greatly. This controller system is small ,easy to fit and a low-cost etc,and is more advantageous to application in agricultural of water matrix.
