The Research And Realization Of Component Technology For WEB Configuration Software

Monitoring and data acquisition are the two important parts of the real-time monitoring system. Configuration software is the direct center of the system. It can be used to display the live picture, set up active properties and show the field data, consequently it will improve the universality and reliability. Component and Web oriented are the new trend and research hotspot of configuration software.This configuration software, which is developed with COM, Object Oriented Technology and Visual Programming Method, has realized a good user interface, ActiveX controls, Web release etc. It mainly includes: the realization of equipment driver control, the design of the user interface control, configuration of development and monitoring of running. Based on the research of the popular configuration software and combining component and Internet technology with the industrial monitoring system, a new distributing component relied on Browser/Server is formed; developing the special driver control used to collect and distribute the real-time field data, communicating with the other controls by script to distribute the data; adopting multithreading technology, memory data managing technology and the high efficiency list structure to store the data in the database, reducing the frequent operation on the disk, this method can advance the real time and reacting speed of the system; designing numbers of ActiveX controls, such as: real-time trend curve data and history trend curve data managing and displaying meter panel data displaying and so on, to display the monitoring picture by research of COM; The whole configuration system centers component, developing special component editor, the configuration can be finished just through simple drag and drop, it's really flexible and convenient; The components communicate with each other through script language, creating HTML document to realize the Web release, finishing the real-time picture renovation and remote monitoring.In this topic the component technology is used to design the configuration software, and the main part of the monitoring configuration software under network has been realized. The function has been validated on the Web and the monitoring picture can be displayed in real time. The topic has achieved the expected aim.
