摘要
高速公路通信设施在保障道路安全、提升运营效率以及实现现代化交通管理中发挥着至关重要的作用。随着广东省高速公路改扩建项目的增加,通信链路的可靠性面临严峻挑战,特别是在复杂施工环境下,光缆频繁中断严重影响了监控系统和站点间的数据传输。通过对多种通信传输方式的优缺点进行深入比较分析,最终确定了VPN传输方案作为通信站至管理中心的备份链路,以提高通信系统的稳定性和安全性。研究表明,VPN传输不仅能够提供高安全性的加密通信,还能够满足高速公路通信系统对带宽和低延迟的高需求,为监控系统和其他业务提供了可靠的备份传输解决方案。
Expressway communication facilities play a vital role in ensuring road safety,improving operation efficiency and realizing modern traffic management.With the increase of highway reconstruction and expansion projects in Guangdong Province,the reliability of communication links is facing serious challenges,especially in complex construction environments,where frequent interruptions of optical cables seriously affect the monitoring system and data transmission between stations.Compares and analyzes the advantages and disadvantages of various communication transmission modes,and finally determines the VPN transmission scheme as the backup link from the communication station to the management center,so as to improve the stability and security of the communication system.Research shows that VPN transmission can not only provide high-security encrypted communication,but also meet the high demand for bandwidth and low latency of highway communication systems,providing a reliable backup transmission solution for monitoring systems and other services.
