摘要
针对WinCC软件多曲线同时显示时难以观察相关性的问题,提出一种多曲线显示新方法。编写VB程序通过ODBC接口访问WinCC数据库,将数据进行无量纲化处理,使其在-1^+1之间变化,并运用组态WinCC画面来显示曲线。实验表明,多曲线显示新方法显示直观,操作方便,比常规显示方法更具有优越性。
Since it is difficult to observe the correlation of multiple data when WinCC display them simultaneously, a new display method was presented. The WinCC database can be accessed by VB program via ODBC interface and then the data are nondimen- sionalized so that all data are among - 1 and 1. A WinCC picture is configurated to display the curves. The experiments show that the new method can display the curves intuitively and the curves are easy to be operated. The new method has more advantages than the conventional display method.
