**1.2.5.2 Digital railway spatial information service portal**

Digital Railway spatial information service portal mainly realize searching and location of railway spatial information services. Through logging spatial information service portal to query, services portal will call the GIS portal service management module to access a specific service path. Service management system called Enterprise Service Bus or GIS services management module, to obtain a specific service path. So users can directly call the service flow path and complete the implementation of the entire business.

Railway spatial information services portal designed the main functions are as follows:


#### **1.3 Digital railway information systems**

Digital Railway information systems are formed by the large number of information systems to support planning, construction and business operation of Digital Railway. Based on the connotation and key characteristics of Digital Railway, and the core business value chain of Digital Railway, Digital Railway information Systems mainly include information systems of planning and design, engineering construction, railway transport organization, passenger & freight transportation services and business management. At the same time, the information systems depend on the Digital Railway infrastructure and Digital Railway mobile equipment. Digital railway information system components, as shown in Figure 4.

### **1.3.1 Digital railway infrastructure**

Digital Railway infrastructure is the digitalization of fixed infrastructure, including road network (lines, bridges, tunnels, and a variety of stations), signal equipment and traction power supply equipment, etc.

The variety of technical equipments of Digital Railway infrastructure should be configured with electronic tags, and layout of the railway lines and stations operate all types of sensors to form a pan in the perception of railway infrastructure environment. Perception of information include various types of railway infrastructure, safety and quality service state, the operation of mobile equipment identification capacity, location and service status, driving environment, wind, rain, snow, earthquake, etc. affect the normal driving state of the weather and the natural environment, goods and passenger service station related information.

Railway spatial information services portal designed the main functions are as follows:

 Distributed GIS Services Integration: integration of data services provide a unified, integrated spatial information services, data services platform is released service. Spatial Services Query: allows users to search the spatial information, which published

GIS Data Services Browse: enables users to browse the map spatial information service

 Service Routing: after user retrieved service, the service call through the feedback information directly to the user's service call request is forwarded to the service providers. Service registration: In addition, the railway geographic information platform provides spatial information services, information sharing through the railway system (platform) in the service registration, the business information system can use Information Sharing Platform for shared services functions, call the railway geographic information platform

Fig. 4. Digital Railway Information Systems

Various types of sensors of Digital Railway Infrastructure communicate with each other by wireless, cable transmission networks, and rolling stock by means of radio frequency transmission protocol to exchange information. Digital Railway infrastructure contains the station interlocking, line occlusion control, signal control, traction control and power transmission, etc. automatic equipment. Digital Railway infrastructure are more accurate and reliable supporting of ATIS (Automatic Train Number Identification System), disaster prevention and safety monitoring, traffic surveillance, emergency command rescue, transport resource management system implementation.
