【摘要】：交通监控、通信和收费是高速公路机电系统中的三大子系统,数据通信是整个系统的基础,本论文对高速公路通信中的时钟同步系统进行了分析研究。文章首先介绍了重庆高速公路核心业务系统的自身特点,时钟同步需要解决的三大业务系统(联网监控系统、联网收费系统、通信系统)之间的时钟异步问题,联网监控内部各子系统(电力监控系统、火灾报警系统、事件检测系统、隧道智能控制系统等)之间的时钟异步问题,各路段之间的时钟异步问题,提出了开发系统的设计思路、实施条件及关键技术点,介绍了系统测试的目的、背景和环境,给出了单元测试、功能测试和系统测试的结果。最后编制系统维护手册和系统日常维护手册设计,从而实现覆盖全路网所有工作站、服务器的时钟同步体系,解决了因时钟异步导致的各种问题,提升了高速公路运营管理的效率。
[Abstract]:Traffic monitoring, communication and toll collection are three subsystems of freeway electromechanical system, and data communication is the basis of the whole system. In this paper, the clock synchronization system in freeway communication is analyzed. Firstly, the characteristics of Chongqing freeway core business system are introduced. Clock synchronization needs to be solved among the three major business systems (network monitoring system, network charging system, communication system) between the clock asynchronous problem, network monitoring internal subsystems (power monitoring system, fire alarm system). The asynchronous clock between the event detection system, the intelligent tunnel control system, and the asynchronous clock between the sections of the road. The design idea, implementation conditions and key technical points of the development system are put forward. The purpose, background and environment of system test are introduced. The results of unit test, function test and system test are given. Finally, the system maintenance manual and system daily maintenance manual are designed. Thus the clock synchronization system covering all workstations and servers in the whole network can solve the problems caused by clock asynchronism and improve the efficiency of highway operation management.
