Real-time Monitor System Design in Large Scale Data Acquisition System

To meet the request for real-time monitor subsystem in large-scale data acquisition system,a design example of monitor subsystem is introduced.This monitor system is used to real-time access to status data and quality data of data acquisition system.This monitor system set different data transmission paths to the kinds of monitor data according to the character of monitor data,and optimize the data transmission.Long-term stable operation shows that the monitor system is reliable and stable.This monitor system has simple structure and high performance of real-time operation,use a combination of hardware and software,and also can be applied to other data acquisition systems easily.
