从目前隧道的设计标准来看,长隧道和特长隧道需要安装监控系统以保证隧道内行车的安全和通畅。随着控制技术、通信技术的发展,现代高速公路隧道监控技术日趋自动化。而隧道本地控制系统是最基本、最重要的隧道控制系统之一,其性能直接决定了隧道监控质量和监控品质的优劣。文章以福建省已建成的福宁高速公路和龙长高速公路为例,详细阐述了隧道本地控制系统的基本功能并对比性的介绍了该系统的多种组网结构。
From the current tunnel design standards, long tunnels and extra-long tunnels need to be installed with monitoring systems to ensure the safety and smooth driving in tunnels. With the development of control technology and communication technology, modern highway tunnel monitoring technology is becoming more and more automated. The tunnel local control system is one of the most basic and important tunnel control systems, and its performance directly determines the quality of the tunnel monitoring and monitoring of the pros and cons. Taking Fu-Ning Expressway and Long-Chang Expressway that have been built in Fujian as an example, this paper elaborates on the basic functions of tunnel local control system and introduces a variety of network structure of the system in contrast.
