The software system is developed based on visual c + + 6 . 0 and microsoft access . the database function is achieved by adopting the database accessing technology of mfc odbc . the software consists of main interface module 、 data acquisition module 、 data analysis module 、 database operation module and report forms print module etc 。 many functions are realized in the software , for example , data acquisition and waveform real time display 、 the display and storage of the detecting result 硬件部分可以对传感器性能进行独立的初步检测,可以对传感器常见问题进行判别;软件部分是在硬件设计的基础上,使用visualc + +软件作为开发平台,结合mfcodbc数据库开发技术,编制了对传感器信号进行分析处理的软件工具,它主要包括主界面模块、数据采集模块、数据分析模块、数据库操作模块及对检测结果报表打印模块等。
After analyzed and compared characteristic of several common interface programs of database , mfc odbc interface of accessing database being abundant functions and operating easily , the thesis studies thoroughly the mechanism that mfc odbc is used to visit database . considering diversity of data formats in dems , file and source database transforming target database are sloved by mfc odbc 论文详细分析与比较了几种常用数据库接口编程，考虑到mfcodbc数据库接口功能丰富，操作相对简便，深入分析mfcodbc访问数据库机理，针对分布式试验与测试系统数据格式的多样性，利用mfcodbc开发并实现了文件数据及odbc源数据库转换到目标数据库过程。
The application of this system developed with visual c + + while soft - sensing models designed with matlab and the sewage database designed with access or sql server 2000 . the thesis integrated the above three into one application system by applying mfc odbc and matlab engine techniques . in general , there are two innovations in the thesis 总之，本文的研究不仅验证了软测量技术应用于城市污水处理过程出水水质参数预测的可行性，还提供了采用matlab 、 visualc + + 、 sqlserver (或access )混合编程的具有创新意义和一定推广价值的具体开发方案。
The actual use and theory analysis indicate that labwindows / cvi development kit can enhance perfectly system real time measurement and control abilities ; detailed data formats can be transformed easily target database by mfc odbc ; real _ time main memory database directly accessing main memory is a perfect scheme to meet the real time requirement ; priority levels and data view that are designed on system characteristics , can solve primely the problem of time sequence consistency ; ntp can basically meet system time synchronization requirement 理论分析和编程实现结果表明labwindows cvi作为测试控制软件开发工具对系统实时测试、控制性能有很大的提高； mfcodbc能极其方便地实现对具体的数据格式进行数据转换；以内存直接寻址方式的实时内存数据库是解决系统实时性的理想方案；针对系统特点而设计的优先级和数据视图能很好的解决系统时序一致性问题； ntp协议软件同步算法基本满足系统同步精度要求。
