Implementation Method of Multi-level Measure and Control Network System Based on ADO Technology

摘要

The design and implement method for distributed isomeric system, including a configuration of three-level measure and control network based on field bus, Ethernet and Internet, and their communication techniques, is described. The data integration and management technique by using VC++ multithreading programming and data-base WEB accessing technique are also presented. A micro-computer monitoring software based on B/S model developed by database accessing method and ADO technique can realize the equipments' concentrate monitoring and control. The system has functions such as of operation analyzing, data searching, running curve and data statistics, report forms printing, etc. According to the fact that the running data stream is great and uneven, statistics database and historical database were used to manage and store data, and the results shows that the system operate conveniently and efficiently.
