The basic requirements of highway network management are discussed as well as the concept of Network Management Information System ( NMIS). With analyzing the NMIS functionally, a possible system protocol is formulated. 概括了公路路网管理的基本要求,提出了路网管理信息支持系统的概念,对系统功能进行了分析,设计了系统结构框架。
A new communication technology based on the highway addressable remote transducer ( HART) protocol 基于HART协议的通信技术
Design and Implementation of Highway VoIP Gateway Based on SIP Protocol 基于SIP协议的高速公路VoIP网关的设计和实现
The highway communication system comprises a service processing and service delivery in two dimensions, the business processing layer completes the conversion of signal and protocol, while business transfer layer achieves signal remote transmission. 高速公路通信系统包括业务处理和业务传送两个层面,业务处理层完成信号和协议的转换,业务传送层实现信号的远距离传送。
HART ( Highway Addressable Remote Transducer) Protocol is a worldwide standard and its products are widely used on smart field devices. 可寻址远程传感器高速通道协议(HART协议)是一项世界范围内通用的适用于智能仪表和控制室设备之间的通信协议。
