草花育苗大棚定时灌溉系统研制

Design of Time Control Irrigation System for Herbaceous Flower Seedling Cultivation in Greenhouse

研究了采用DS12C887提供实时时钟、单片机AT89S51进行控制的草花育苗大棚灌溉系统。该控制系统采用模块化的设计,把时钟单元设计成了一个单独的模块,这样可以向任意多的定时单元提供实时时钟信号,所以控制系统有很好的扩展性,可以根据大棚的数目来扩展控制器的数目。通过现场调试,其运行满足实际要求。

A time control irrigation system for herbaceous flower seedling, which was based on a real time clock chip of DS12C887 and a MCU of AT89S51, was designed in this paper. Modules design was adopted for this system and the clock unit was designed to be an independent module. So the real-time clock signal could be supplied m the fixed time units as many as wanted. Therefore the control system could be convenient to extend and the quantity of the controller could be increased according to the quantity of greenhouse. The system fulfilled the, demand through local debug.
