【摘要】：交通監(jiān)控、通信和收費(fèi)是高速公路機(jī)電系統(tǒng)中的三大子系統(tǒng),數(shù)據(jù)通信是整個系統(tǒng)的基礎(chǔ),本論文對高速公路通信中的時鐘同步系統(tǒng)進(jìn)行了分析研究。文章首先介紹了重慶高速公路核心業(yè)務(wù)系統(tǒng)的自身特點(diǎn),時鐘同步需要解決的三大業(yè)務(wù)系統(tǒng)(聯(lián)網(wǎng)監(jiān)控系統(tǒng)、聯(lián)網(wǎng)收費(fèi)系統(tǒng)、通信系統(tǒng))之間的時鐘異步問題,聯(lián)網(wǎng)監(jiān)控內(nèi)部各子系統(tǒng)(電力監(jiān)控系統(tǒng)、火災(zāi)報警系統(tǒng)、事件檢測系統(tǒng)、隧道智能控制系統(tǒng)等)之間的時鐘異步問題,各路段之間的時鐘異步問題,提出了開發(fā)系統(tǒng)的設(shè)計思路、實(shí)施條件及關(guān)鍵技術(shù)點(diǎn),介紹了系統(tǒng)測試的目的、背景和環(huán)境,給出了單元測試、功能測試和系統(tǒng)測試的結(jié)果。最后編制系統(tǒng)維護(hù)手冊和系統(tǒng)日常維護(hù)手冊設(shè)計,從而實(shí)現(xiàn)覆蓋全路網(wǎng)所有工作站、服務(wù)器的時鐘同步體系,解決了因時鐘異步導(dǎo)致的各種問題,提升了高速公路運(yùn)營管理的效率。
[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.
