摘要
针对实时网络系统设计,提出了基于反射内存的实时网设计方法,介绍了利用反射内存实现实时通讯的原理和基于VMI-5565反射内存卡的实时网络的组建方式.分析了2种反射内存地址分配方式、通讯过程并给出了实时通讯协议,同时简要说明了在Windows系统下实现实时通讯的方法,最后对该实时网络的性能进行了定性分析并给出了实际的测试结果.
Aiming at the real-time network system design, the real-time network design method is put forward based on the reflection memory. The principle of using the reflection memory to effect real-time communication and the formation method of real-time network based on the reflective memory card ( VMI-5565 ) is introduced. The allocation method of two reflective memory address and the communication process are analyzed and the real-time communication protocol is given as well. At the same time, the method of realizing real-time communication under Windows system is briefly explained. Finally, the qualitative analysis of this real-time network's performance and the actual test results are presented.
