摘要
本文以一种综合运用VC++和世纪星组态软件两种平台共同开发实现的"煤矿井下安全生产监测监控系统"为例,介绍了利用内存文件映射技术实现进程间动态数据交换的方法。详细说明了了利用内存文件映射实现共享内存的原理及其实现步骤,并给出系统编程实例。性能分析及系统认证都证明了该方法的高效性和系统的实时性。
In this paper, the memory mapping file technology that is used for realizing the shared memory was introduced, which was exemplified by the colliery safety monitoring system based on the Visual C＋＋ and Century Star configuration software. The implementation principles and the steps of memory mapping file technology were analyzed in detail and explained by an example. The system was verified by analysis with the request target and experiments.
