The Design And Lmplementation Of Computer Monitoring Chief Station On Heat Network

This paper comes from a practical project. It begins with a brief introduction to the development and the trend of the computer monitoring system on heat network, followed by the system analysis and the entire design. Then this paper describes the implementation of the Chief Station in detail which is an important part in this system.The software of the Chief Station is composed of monitoring module and communicating module. The monitoring module involves the use of PC-LabCards, the method of a precise timer, the principle of PID autocontrol and how to use it in the project, the realization of all kinds of reports with the OLE automation skill, while the communicating module discusses the way of communication between the Chief Station and the Scheduler based on the C/S structure. Both monitoring module and communicating module are established on the database, so this paper particularly describes the access methods to MS SQL Server and the advantage of database stored procedure.Finally, this paper concludes the autocontrol software design experience.
