摘　　要：文章利用PLC和触摸屏搭建了农产品筛选系统,该系统通过称重传感器和红外传感器将数据传送到PLC,PLC对采集到的农产品信息实际值与预定值进行比较,输出信号驱动电动推杆,实现对传输带上的农产品的大小甄别。该系统亦可使用触摸屏进行手动和自动控制。By using PLC and contact screen,the paper builds up a sifting system for farmer products,which delivers information from weight weighing sensor and infrared sensor to PLC. By comparison with given values,PLC outputs signals to drive the push rod,to realize the screen of farmer product size. The system is avail able used for manual and automatic control.
