Real-time DSTN Simulation System in HLA-RTI Emvirconment

文中介绍了以一种HLA-RTI为基础环境的公用电话网实时半实物仿真方法,通过构造HLA仿真联盟成员,将OPNET中建立的PSTN七号信令模型,引入了RTI平台,设计实现了PSTN硬件数据采集模块,实时收发PSTN数据,并搭建了仿真实验平台,实验证明该平台仿真效果好,拟真度高。随后,对仿真时间推进算法作了适当改进,降低了系统的计算负荷。

This paper proposes a method for PSTN simulation by Hardware-in-the-Loop in the HLA-RTI enviroment. The model of SS7 into the RTI is introduced platform by means of construting the HLA-federates. A PSTN data-collection model is designed by means of hardware in order to send or receive the data of the PSTN at real time. A platform of the simulation experiment is coonstructed, and the experiments indicate that this platform has good simulation effect and is similar to reality. Consequently the arithmetic of the simulation is properly inproved and thus the calculating load of the computer also trduced.
