灌溉施肥自动控制系统的研究与开发

Development of Automatic Control System of Fertigation Technique

为了实现滴灌系统中灌溉与施肥的精确控制和同步进行,应用单片机控制与变频调节技术设计、开发了高精度的灌溉施肥自动控制系统,并通过硬件和软件的优化组合,进行了灌溉施肥自动控制系统的自主设计和制造.根据不同作物的不同需要,对灌溉液的电导率和酸碱度进行精确控制和实时调节,利用单片机技术开发了自动施肥控制系统,降低了系统成本.该系统采用模块化设计,其结构紧凑,使用简单,有利于推广使用.

To accurately control and simultaneously conduct of irrigation and fertilization in drip irrigation system, a highly intelligent fertigation system is developed based on single chip microcomputer （SCM） control principles and variable frequency technique. Via the optimal combination of hardware and software, the equipment is fabricated, where the electric conductivity and pH value can be accurately controlled and real-time regulated to meet the various needs of different crops. Utilizing SCM technique reduces the costs of the system, while the structure becomes much compacted due to the modular design to efficiently promote.
