农作物最佳喷灌时间是在早晨和傍晚。笔者利用鸣闹石英钟(24小时内鸣闹一二次)作启动信号,用IC555制作定时控制器,就可以实现每天早、晚两次全自动定时喷灌。当电源发生断相故障时,本装置还能自动切断电机电源保护设备。经本地干旱区实地使用证明,本装置新颖、实用、可靠,在干旱区和半干旱区推广运用有重要的意义。
Crop irrigation time is best in the morning and evening. I use the quartz alarm clock (24 hours a week or two) as a start signal, with IC555 production timing controller, you can achieve daily morning and evening twice automatic sprinkler irrigation. When the power failure occurs, the device can automatically cut off the motor power protection device. The field use of the local arid area proved that the device is novel, practical and reliable, and it is of great significance to promote the use in arid and semi-arid areas.
