【摘要】：近年来我国铁路建设经历高速发展,铁路运营里程达12.4万公里,随着铁路的不断发展,铁路安全因素也随之增多,突发事件呈现种类多和影响大的现象。铁路运输突发事件的应急救援和处置是铁路运输安全工作的一项重要内容。为辅助铁路应急工作,在原铁道部(现中国铁路总公司)组织下,铁科院电子所研制了铁路应急平台,并使用至今。现用铁路应急平台功能不够完善,铁路总公司与各铁路局应急平台数据不能共享,不能充分利用各铁路局的资源等数据,包括属性数据和空间数据。因此,铁路总公司应急管理部门对应急平台提出升级、优化、整合要求,并实现基于GIS的突发事件处置功能。本文研究以升级铁路应急平台目的,并重点介绍GIS功能的实现。为确保平台升级后能发挥铁路应急作用,本文首先对平台的数据需求和功能需求进行了分析整理。其次,为实现平台的GIS功能,对GIS技术和传统GIS系统组成进行了研究分析,发现传统方式成本高,不利于维护,更重要的是不能实现空间数据的共享。因此提出基于铁路地理信息平台(RGIS平台)升级铁路应急平台的技术路线,并重点研究其中的REST式架构风格、权限控制技术与HMAC-SHA1加密算法。然后,对铁路应急平台的升级进行详细设计,包括系统的总体架构,数据的同步与处理,表结构的设计,GIS与非GIS功能的设计和关键技术运用的设计。最后,阐述平台升级的基本过程,并实现铁路应急平台,展示简述重要功能模块。
[Abstract]:In recent years, railway construction in China has experienced rapid development, and the mileage of railway operation has reached 124000 kilometers. With the continuous development of railway, railway safety factors have also increased. The emergency rescue and disposal of railway transportation emergencies is an important part of railway transportation safety. In order to assist the railway emergency work, the railway emergency platform has been developed by the Electronics Institute of the Institute of Railways under the organization of the former Ministry of Railways (now China Railway Corporation), and has been used up to now. At present, the function of railway emergency platform is not perfect enough, the data of emergency platform between railway corporation and railway bureau can not be shared, and the resources of each railway bureau, including attribute data and spatial data, can not be fully utilized. Therefore, the emergency management department of Railway Corporation puts forward the requirements of upgrading, optimizing and integrating the emergency platform, and realizes the emergency handling function based on GIS. In this paper, the purpose of upgrading railway emergency platform is studied, and the realization of GIS function is emphasized. In order to ensure that the platform can play an emergency role after upgrading, this paper first analyzes the platform's data requirements and functional requirements. Secondly, in order to realize the GIS function of the platform, the GIS technology and the traditional GIS system composition are studied and analyzed. It is found that the traditional method has high cost, which is not conducive to maintenance, and more importantly, it can not realize the sharing of spatial data. Therefore, the technical route of upgrading railway emergency platform based on railway geographic information platform (RGIS) is proposed, and the REST-style architecture style, privilege control technology and HMAC-SHA1 encryption algorithm are studied. Then, the upgrading of railway emergency platform is designed in detail, including the overall structure of the system, the synchronization and processing of data, the design of table structure, the design of GIS and non-GIS functions and the design of key technologies. Finally, the basic process of platform upgrading is described, and the railway emergency platform is realized.
