摘要
在液压综合试验台测控系统中,由于试验种类多,试验持续时间长,导致试验记录数据庞大。为避免由庞大数据在查询以及管理上带给组态软件WinCC的负担,提出了一种新的数据归档方法。该方法将试验的信息与数据通过ODBC接口导出,分别存入Access及记事本中。利用VB6.0编写一个查询程序作为WinCC的扩展功能模块,紧密嵌入WinCC运行环境。在WinCC的内部对该模块进行调用,从而解决了WinCC对历史数据访问方式死板等问题。实现对过程数据的归档、历史数据的检索、报表生成打印以及动态数据显示等功能。
In the integrated measurement and control hydraulic system,the diversity and long duration of test result in a large test record data.In order to avoid large data query and management burden during WinCC configuration software in the using of monitoring,a new method for data archiving has been proposed.This method will send the test information and test data derived by WinCC,respectively,to notepad and Access database.Then a query using VB6.0 program as an extension function module tightly embedded in the WinCC runtime environment.The WinCC internal calls to the module enable the archiving of process data,historical data retrieval,report generation,printing,and dynamic data display.
