WinCC组态软件功能强大,但是它的报表功能并不完善,网络报表的功能需要通过昂贵的组件Web Navigator采实现,有时无法满足项目需求。针对WinCC报表功能的不足,在研究分析了WinCC数据归档结构后,基于Ajax,ASP等网络技术提出了实现WinCC网络报表系统。系统直接读取SQL Server归档数据库,实现远程浏览WinCC报表、趋势图表的功能,同时具有类似桌面程序的用户体验。将该系统应用于某污水处理过程中取得了良好的效果。
WinCC configuration software is powerful, but its report function is not perfect. The function of the network report needs to be realized by the expensive component Web Navigator, sometimes it can not meet the project requirements. In view of the deficiency of WinCC report function, after analyzing and analyzing the structure of WinCC data archive, this paper proposes the realization of WinCC network report system based on Ajax, ASP and other network technologies. The system reads the SQL Server archive database directly to realize the functions of remotely viewing WinCC reports and trend charts, and at the same time has the user experience similar to desktop programs. The system has been applied to a sewage treatment process has achieved good results.
