組態(tài)王環(huán)境下數(shù)據(jù)庫訪問技術(shù)及其應(yīng)用

組態(tài)軟件具有強(qiáng)大的數(shù)據(jù)庫功能，但是其數(shù)據(jù)分析功能卻十分薄弱。因此在需要對(duì)采集數(shù)據(jù)進(jìn)行數(shù)據(jù)分析時(shí)，就需要將組態(tài)軟件數(shù)據(jù)庫中的數(shù)據(jù)取出送到其他軟件如MATLAB中進(jìn)行分析。本文針對(duì)該情況，以“組態(tài)王”為例，提供了兩種訪問數(shù)據(jù)庫的方法，并對(duì)兩種方法進(jìn)行了分析，為解決組態(tài)軟件數(shù)據(jù)庫的訪問問題提出了切實(shí)可行的方法。

Database and It’s Application Under KingView LI Yan-fei, ZHANG Wei-dong, WU Jie-chang, CHEN Guo-jun (Ship and Power Eng. College, Naval Univ. of Engineering, Wuhan 430033, China) Abstract: The configuration software has powerful data-base, but the ability of data analyse is very poor. When we need to analyze some parameters, they must be exported to other software as MATALB. In this paper, two methods of visiting KingView’s database are introduced, and the result shows that these methods are viable.
