基于单片机的温室渗灌控制系统设计

Design of Control System with Single Chip for Greenhouse Seeping Irrigation

设计了一种用于温室自动渗灌的控制系统,拟解决以往温室渗灌不能准确地控制土壤湿度的问题。对系统的功能、系统电路的搭接以及程序的编写进行了详细的论述。控制器采用89C51单片机,充分利用了单片机的I/O引脚,传感器采用北京澳作公司生产的AZS-2型测试探头;同时,利用HH2 Moisture Meter对系统的检测功能进行了标定,并进行了对比测试试验。试验结果表明,系统检测功能良好,实际操作证明控制系统能够实现预定的功能。

A sort of automatism control system be designed in this passage, which be used for seeping irrigation in greenhouse and purpose to give a nicety control for seeping irrigation in greenhouse. The function of the system, building of the circuit and programs were dissertated in detail. The MCU is adopted 89C51 single chip, the I/O ports were fully used, the sensor is AZS--2 detector.produced by Beijing AOZUO Co.Ltd. The detection function of the .system be calibration by HH2 Moisture Meter. Contrast experiment be done, result indicate the detection function is good. Practicality operation indicates that the control system can realize the designed function.
