摘要
利用PLC对联合收割机室内仿真试验台中脱粒滚筒的转速、转矩及喂入量等信号进行采集 ,并设计了PLC和上位机中LabVIEW的串行通信系统 ,将采集到的数据在上位机中存储、显示和回放。该系统已应用于仿真试验台的实际工作中 ,试验证明其工作性能稳定、界面友好。
A data acquiring system based on PLC and LabVIEW which is used in the simulation and control equipment for combine experiment is expounded.It is used to measure the rotating speed and torque of the threshing cylinder and the feed quantity of the threshing unit.The serial communication system between the PLC and LabVIEW is introduced too.So the data can be transferred to PC for displaying,saving and replaying.
