Research and Development of Control System Based on LabVIEW and PLC
With the close integration of computer software and measurement and control system,the structural concept and design concept of the instrument itself have undergone breakthrough changes,so a new instrument concept has emerged-virtual instrument.This instrument technolo-gy is an organic combination of traditional measurement and control technology and computer technology,using LabVIEW software program using block diagrams and Siemens PLC program.The measurement and control technology system based on virtual instruments is mainly com-posed of three parts,namely human-computer interaction interface,test control part,and data ac-quisition part.The operator only needs to watch the intuitive human-computer interaction inter-face,and can clearly control all kinds of data information in the control system,and the whole process is easy to operate,which greatly promotes the design process and improves the compre-hensiveness of the device,which has certain positive significance.
