摘要： 随着路网的逐渐形成，高速公路区域联网监控系统已成为现代高速公路发展的必然趋势.然而，由于缺乏统一的监控数据通信协议，直接导致了区城联网监控系统建设步伐的停滞不前.本文在解析了IEC-60870-5系列协议的基础上，分别探讨了变电站系统与高速公路区域联网监控系统的系统体系结构与数据信息.考虑到两者的体系结构相似、数据信息相近，提出了电力远动通信协议在路网监控系统上的移植.此外，基于IEC60870-5-101,104协议所规定的数据格式及语义要求，拟定了高速公路区域联网监控数据的通信协议，主要包括应用层ASDU的数据单元标识符、信息对象等，并进一步给出了具体的ASDU格式该拟定协议技术成熟，具有兼容性强、可靠性高、适用性好、可扩展性广等多种特点.

Abstract: With the formation of expressway network, the expressway online monitoring system has been the inevitable trend of modern expressway development. However, for the lack of the unitive communication protocol of monitoring data, the. construction step of expressway online monitoring system is stagnant. Based on the analysis of the IEC-60870-5 protocol series, this paper discusses the system structure and data information of transformer substation system and expressway online monitoring system respectively. Considering the similarity of their system structure and data information, the transplanting of power telecontrol communication protocol to the monitoring system
of expressway network is produced. In addition, the communication protocol of expressway online monitoring system, which mainly includes data unit identifier and information object of ASDU, has been drafted according to the data format and semantenne, defined by IEC60870-5-101 and 104. Meanwhile, a detailed ASDU format is also shown. The draft ofp rotocol, which adopts mature technologies, is of strong compatibility, high reliability, good applicability, large expansion and soon.
