摘要
研究了南疆地区棉花节水灌溉温度控制系统,控制系统采用单片机为智能控制器,太阳能电池板为控制电源,通过数字温度传感器自动采集棉花田间的空气温度参数,将信号输入单片机中判断温度下限值,温度过低时自动停止灌溉。下位机和上位机之间通过串口通信,温度信号实时显示在VB窗口。结果表明,该系统成本低、灵活好用、自动化程度较高、节省了人力物力,适合在南疆大田地区进行节水灌溉控制。
The water-saving irrigation of cotton with temperature control system in southern Xinjiang was studied. The control- ling system used single-chip intelligent controller, solar panels for the control of power. Digital temperature sensor automati- cally collected air temperature parameters of the cotton fields, determined temperature limit signal and inputed microcontroller. It automatically stopped when the temperature was too low for irrigation. Between the lower machine and the host computer via serial communication, real-time temperature signal displayed in VB window. The results showed that the system was low- cost, flexible and easy to use with high degree of automation. It can save manpower and resources, suitable for water-saving irrigation in the southern regions of Xinjiang.
