Development of Data Acquisition and Control System with High Speed and Long Distance

A data acquisition and control system for a safety valve test bench with high pressure and large flow rate, was developed based on the host-slave architecture, which takes an Industrial Personal Computer (IPC) as host computer and a Programmable Automatic Controller (PAC) as salve computer. The hardware architecture and software design of this system were introduced in detail. This system was verified by the experiment, and the results indicate that it can fulfill the requirement of data acquisition and control with high speed and long distance. This study can provide reference for many automation control fields.
