基于C#组态软件中数据库系统的设计

在数据库系统中，先介绍了生产现场中对变量的分类，并列出存储变量的数据库表的结构。实现了现场检测参数的自动存储，并自动更新数据库。根据I/O信号进行数据单元配置，完成数据库的组态，数据库通过数据采集程序对现场数据进行读写，并按照设定好的存储策略将其保存到历史数据库中。数据库子系统实现通信，对象查找，内容修改更新等功能。采用Windows XP作为系统开发环境，Visual C#作为开发工具。

design of the Computer-monitored Configuration software database system based on C#

In the database system, introduced ifrst in production site to the classiifcation of variable, and lists the memory variable the structure of database table. Has realized the auto-storage of detection in situ parameter, and automatic renewal database. Carries on data unit disposition according to the I/O signal, completes the database the conifguration, the database carries on the read-write through the data acquisition procedure to the ifeld data, and defers to establish the good memory strategy to preserve in the historical database it. The database subsystem realizes the communication, the object searches, content revision renewal and other functions. With Windows xP as system development environment, Visual c# as development tool.
