摘要
针对Wonderware平台自带的历史数据服务无法满足大量历史数据同时存储的问题,对该平台的历史数据服务进行了研究和分析,在保证Wonderware平台存储历史数据的正确性、及时性和完整性的前提下,结合Wonderware平台与.NET能够兼容的特性,设计了一种新的历史数据存储方法,使用C#语言完成了基于.NET的自定义历史数据库的开发并投入实际使用,运行效果良好。
Aiming at the problem that it is impossible to store mass data simultaneously by the build-in historical data service on Wonderware platform, this historical data service is studied and analysed. Under the precondition of validity, timeliness and integrity of historical data storage on Wonderware platform, a new method of historical data storage is designed combined with the property which Wonderware platform can work with.NET platform compatibly. The user-defined historical database is developed by C# which is based on.NET and is running well actually now.
