基于VC++的分布式异构数据系统集成的实现

Implementation on Distributed Heterogeneous Data System Integration Based on VC++

针对分布式异构数据系统集成的特点和所面临的问题,以北京西站楼宇设备为应用对象,介绍了一种分布式异构环境下基于VC++实现系统集成的方法,包括与各子系统之间数据交换的实现、通信方式的选择、通信协议和配置文件的设计、基于多线程技术的稳定串行通信的实现方法;实践证明该方法设计简单、灵活,软件运行稳定、可靠,有针对性地解决了分布式异构系统带来的软件开发难题,在北京西站得到了成功应用。

Aiming at the characteristics and problems of distributed heterogeneous data system integration and taking Building Devices of Beijing West Railway Station as application object, a kind of method of system integration is presented based on VC＋＋ under distributed isomeric condition. This method includes the realization of data exchange between host system and subsystems, the option of communication mode, the design of communication protocols and configuration files and the implementtation of serial communication based on multithreading technique. This method is proved to be effective, which makes the design simple, flexible and the ,software run steadily and reliably. This method can be used to settle software development problems in distributed heterogeneous system and applied successfully to Beijing West Railway Station.
