Research And Implementation Of Data Monitor Technology Based On Client And Server(C/S) Model

With fast development of Computer and Industry control technology, more and more large-scale industrial companies choose to use industry monitor software to manage and supervise their enterprises in order to optimize control and management in industry process. But there is no standard in the real-time monitor systems until now. There are different demands in different areas. When a new system needs to be developed, designing and coding must be repeated. It leads to not only great waste of resources, but also heavy work of system maintenance.Based on former monitor systems' codes and models as well as documents which are proved by practice, our teachers put forward the real-time supervisory platform ideology. This paper uses software reusing and system expending ideology to design and implement the data monitor client subsystem.This paper's assignment is to design and fulfill data monitor client subsystem. Data monitor client subsystem is one of the most important parts of the real-time supervisory platform. Using interface, data monitor client subsystems gains the real-time datum which collected from data service subsystem and uses various methods such as curve graph and pie graph and so on to monitor the data points. These enable users to watch devices' running circumstance intuitively and make decision conveniently. This paper uses the oriented-language C# and .NET component technology as well as GDI+ technology to design the data monitors client subsystem based on .NET platform. Using C/S model and factory pattern, this thesis creates various monitoring components to implement the data monitor client subsystem and reserve interface for software reuse.
