摘要
在现有高速公路联网收费数据网络的基础上,采用UDP协议和可视化编程进行了对讲系统的设计,提出了通话过程的实现方法,满足了收费工作中话音全双工传输的要求。该系统可通过高速公路SDH综合业务接入网方便地实现网络连接,为高速公路各级管理提供实时信息。
Based on the present highway toll collection net, a bi-way voice communication system is designed via UDP protocol and visual programming, and the communication process realization is also supplied. This system can meet the voice bi-way transmission requirements in toll collection. This system can achieve the net interconnection via highway SDH integrated service access net readily and to supply the real time information for all highway administration levels.
