嵌入式故障录波装置中Windows CE系统下多用户访问数据库的软件实现

Realization of multiple user access the database in WinCE system in terms of the embedded fault record device

一般对数据库的访问多是通过调用OLEDB接口进行直接I/O读写。而在需要多用户频繁访问数据库的系统中,这种访问方法就不能满足要求。嵌入式故障录波装置通过采用嵌入式WinCE系统,做到了采集站和分析站的功能合并,实现了多用户频繁访问SQLServerCE数据库的软件设计思想。

Generally, databases are accessed by transferring OLEDB interface in a way similar to reading and writing I/O directly. However, this method does not allow multiple users to access a database at one time.The functions of gathering-station and analyzing-station are combined in the embedded fault record device through the WinCE system, which fulfills the idea of soft design by allowing multiple user access to the SQL Server CE database.
