Title Control system design and Realization of dynamic data exchange technology
Abstract
Process control is an important branch in industrial automation,in metallurgy, machinery, chemical industry, electric power and other aspects ,it has a wide range of applications.Process control is mainly refers to liquid level, temperature, flow and other process variables in control, in which the liquid level control technology in real life, plays an important role in the production.
This paper takes water tank level control system as the research object, using the PCL-812PG interface card to design the water tank level control system. Aiming at the characteristics of water level control system, using VC++ to design level single loop fixed value control system software, using Intouch industrial configuration software to finish the design of the monitoring interface of the system, and using dynamic data exchange technology to achieve the real time data exchange of the monitoring software and control software .
Keywords Process control PID algorithm Intouch software DDE
