在战争中失去指挥是最严重的事情,而指挥离不开通信。同样,通信系统是城市轨道交通大系统的重要组成部分,是轨道交通实现信息化、智能化的基础,是保证行车安全、提高运输效率和管理水平的重要基础设施。人们常常把轨道交通的通信系统比喻为人体的“神经系统”,可见其地位之重要。
随着信息技术的突飞猛进,通信领域的技术装备日新月异;但无论是有线通信还是无线通信,无论是卫星通信还是量子通信,都必须依靠先进、可靠、标准化的的技术装备和设施来提供保证。因此,《城市轨道交通通信系统工程安装技术指南》以及《城市轨道交通通信系统工程安装图册》两本著作的出版,令人鼓舞。
近5年来,我国共建成城市轨道交通线路4 150 km,运营线路的总长度领跑世界,累计完成客运量600亿人次。5年的快速发展不仅让城市轨道交通成为百姓日常出行的首选,更有力地拉动了城市经济的发展。到2020年,全国建设城市轨道交通的城市将达到50个,总长度将达到9 600 km,基本形成布局合理、功能完善、干支衔接、技术装备优良的城际、城市轨道交通网络。展望未来,轨道交通建设者及管理者任重而道远。
城市轨道交通通信系统建设是“中国制造2025”十个重点领域中“新一代信息技术产业”、“先进轨道交通装备”项目的具体实践。提升城市轨道交通通信系统工程的施工质量,是实施“中国制造2025”国家战略的客观要求。
城市轨道通信系统的子系统多,设备构成多样、技术更新快、集成度高,编制其全面的工艺标准图册难度大、工艺标准难以统一。在这样的背景下,体现当前城市轨道交通通信系统管理要求及工艺标准的《城市轨道交通通信系统工程安装技术指南》及《城市轨道交通通信系统工程安装图册》的编写,就显得十分必要。两书本着通信系统施工质量控制、规范施工技术要求、统一施工及验收标准、突出施工工艺的原则,同时遵循我国现行的国家标准、行业标准及有关规定编写而成,适用于城市轨道交通通信系统的工程施工,对科研院所、设计院、高校师生也具有参考价值。
《城市轨道交通通信系统工程安装技术指南》对我国城市轨道交通通信系统的工程施工能起到统一规范和推广标准的作用;《城市轨道交通通信系统工程安装图册》更是图文并茂,对通信系统的每一道作业工序、施工工艺都进行了详实有序、内容饱满的讲解,让通信施工不再神秘,且更加专业化、系统化、大众化。因此,两书的出版,必将对城市轨道交通通信施工工程的规范化发挥重要作用。
正当笔者撰写本文之际,2017年10月13日从阿联酋阿布扎比传来了一个好消息:上海获得2021年第46届世界技能大赛举办权,国家主席习近平在申办陈述阶段通过视频发表致辞。当前,无论发达国家还是发展中国家,技能型人才的占比都偏低。这种状况亟待改变。这两本书的写作、编辑、出版,还将有利于人才培养观念的转变,有利于弘扬工匠精神,有利于广大职工关注、热爱、投身技能事业,有利于高素质技能人才的培养。

Losing commanding at war is the most serious thing,and commanding is inseparable from communications.In the same way,the communication system is an important component part of the urban rail transit system.It is the basis of rail transit′s realizing informationization and intellectualization,and is also an important infrastructure to ensure traffic safety,and improve transportation efficiency and management level.The communication system of rail transit is often likened by people to the“nervous system”of the human body,so the importance of its status could be seen.
With the information technology′s advancing by leaps and bounds,the technical equipment in the communication field is making progress with each passing day,but whether it is wired communication or wireless communication,and whether it is satellite communication or quantum communication,they all must rely on advanced,reliable and standardized equipment and facilities to provide assurance.Therefore,the publication of the two works of“The Installation Technique Guide of Urban Rail Transit Communication System Engineering”and“The Installation Illustrated Book of Urban Rail Transit Communication System Engineering”(herein after referred to as “The Installation Technique Guide”and “The Installation Illustrated Book”)is encouraging.
In the recent five years,China has built up 4 150 km urban rail transit lines,the total mileage of metro operation lines has led the world,and urban rail transit has completed 60 billion person-times passenger transport volumes.The rapid development of five years not only has made the urban rail transit become the first choice for people's daily travel,but also has powerfully pulled the urban economic development.By 2020,the cities that have constructed urban rail transit lines will have reached 50,the total construction mileage will have reached 9 600 km,basically forming intercity and urban rail transit networks of reasonable layout,perfect function,trunk lines′linking with branch lines,and excellent technical equipment.Still,for rail transit builders and managers,the task will be heavy and the road will be long.
The constructions of the urban rail transit communication system are the concrete practice of“new generation information technology industry”and“advanced rail transportation equipment”items in 10 key areas of“China Manufacturing 2025”,and the improvement of construction quality of urban rail transit communication system engineering is the objective requirement of implementing the national strategy of“China Manufacturing 2025”.
The urban rail communication system has many subsystems,its equipment composition is diverse,its technologies update fast and the integration degrees are high,so compiling an overall technology standard illustrated book is very difficult,and its technology standards are not easy to be unified.Under such a background,it is very necessary to compile the two works of“The Installation Technique Guide”and “The Installation Illustrated Book”that embody the current management requirements and technology standards of the urban rail transit communication system.“The Installation Technique Guide”and“The Installation Illustrated Book”are compiled in accordance with the principles of communication system construction quality control,standardizing construction technical requirements,unifying construction and acceptance standards and highlighting construction technologies,and at the same time,following our country′s current national standards,industry standards and related provisions.They are applicable to the urban rail transit communication system constructions,and also have reference value to scientific research institutes,design institutes and college teachers and students.
“The Installation Technique Guide”can play the role of unifying norms and promoting standards to China′s urban rail transit communication system engineering constructions.“The Installation Illustrated Book”is still that both the pictures and their accompanying essays are excellent,making the detailed,orderly and full-content explanations to each working procedure and each construction technology process of the communication system,so that communication constructions are no longer mysterious and are more professional,systematic and popular.Therefore,the publication of this book will certainly play an important role in the standardization of urban rail transit communication construction projects.
Just as the author was writing this article,on October 13,2017,a piece of good news came from Abu Dhabi in the United Arab Emirates.Shanghai won the rights to host“The 2021 46th WorldSkills Competition”.President Xi Jinping delivered a speech via video at the bid presentation stage.Currently,in both developed and developing countries,the proportions of skilled talents are all too low.This situation urgently needs to be changed.Writing,editing and publishing of these two books will also be beneficial to the transformation of the talent cultivation concept,carrying forward the spirit of craftsman,the workers′attention to,love for and devotion to the skills cause and the cultivation of highly qualified skilled talents.
(Note:The editors of the two books of“The Installation Technique Guide of Urban Rail Transit Communication System Engineering”and“The Installation Illustrated Book of Urban Rail Transit Communication System Engineering”are China Railway Signal&Communication Shanghai Engineering Bureau Group Co.,Ltd. (CRSCS).The two books will be published by China Railway Publishing House.)
