Among them, the micro-service architecture is an architectural model, which can divide a single application into a group of small services, and the services coordinate and cooperate with each other to provide the final value to the users. Each service is built around a specific business and can be deployed independently to a production environment, a production environment, and so on. Although the rail transit business is complex, the micro-service architecture can break down the huge rail transit business into multiple specific services, which not only solves the complexity problem, but also makes the single service easy to develop, understand and maintain. The micro-service architecture mode enables each service to be extended independently. For example, when the alarm service capability component cannot process a large number of device upload data, the number of alarm service capability components can be increased, thereby meeting the problem of an increasing number of devices.

It can be understood that the specific business logic of each platform in the software as a service layer (SaaS) 21 can be provided by the underlying shared service capability center 22. For example, the user component of the shared service capability center 22 can provide user data for each platform of the software as a service layer (SaaS) 21 through a unified interface. Since all the platforms can retrieve data from the shared service capability center 22 through a unified interface, the data format can be consistent, and since the shared service capability center 22 is open to all platforms, data can be interconnected and implemented in various professional systems. Data sharing for all business systems.

It should be noted that when the shared service capability center 22 provides data to each platform of the software as a service layer (SaaS) 21, data selection and provision may also be performed according to the rights of each platform. Only when a platform of the software as a service layer (SaaS) 21 has the right to retrieve data, the data corresponding to the authority is provided to the corresponding platform, thereby ensuring the security of the data in the information system cloud platform.

The rule engine service is used to provide a unified rule engine service to the shared service capability center 22 of the information system cloud platform. The rule engine can separate the business decision from the application code and simplify the implementation logic of the upper layer system.

Message Queuing Middleware is an important component of the information system cloud platform. It mainly solves the problems of strong coupling, asynchronous messaging, and traffic clipping of upper-layer services and systems. Message Queuing services enable high performance, high availability, scalability, and ultimately consistent architecture.

The distributed cache service is an in-memory database service compatible with the Redis communication protocol, which is used to satisfy the high-level read/write performance and fast data access of the upper-layer system.

Integrated bus service is an open platform of service application programming interface (API) based on high-availability distributed technology, which can realize service interoperability across technology platforms and cross-application systems.

Distributed computing services provide a wide range of application publishing capabilities and lightweight microservice solutions that address monitoring, diagnostics, and high availability operations in application and service management.

Business monitoring services can integrate and encapsulate various advanced Internet technology components such as data collection, message channel, real-time computing, columnar storage, and online reporting, providing various scenarios such as system monitoring, passenger flow analysis, and fault prediction for the upper system. Monitoring service.

Real-time computing services, based on a streaming big data analytics platform, provide tools for real-time analysis of streaming data on the cloud.

Security and authentication services can provide professional security services such as network security, data security, transmission security, and access security for the information system cloud platform.

It can be understood that the middleware layer 23 provides a unified middleware resource for the operation of the information system cloud platform, so that unified data storage, unified interface components, and unified message delivery can be realized, thereby realizing Interoperability and data sharing.

The above analysis shows that the cloud platform of the rail transit information system provided by the embodiment of the present invention relies on the cloud platform architecture system such as virtualization, Internet middleware, big data, etc., and builds a microservice-based shared service capability center based on the above. 22. Unified unified upper rail transit professional systems provide unified interfaces and data services. Compared with the traditional single-architecture architecture, the micro-service architecture has the ability to deploy independently and scale horizontally on demand. This makes it necessary to increase the computing resources such as servers when the lines and devices are added, without modifying the software architecture. System and code. In the information system cloud platform, integrating various hardware, software, and other resources, such as servers, storage, and networks, which are distributed in various lines, makes centralized operation and maintenance possible, which can effectively reduce the number and cost of operation and maintenance personnel.

For example, the external service network can provide passengers with external services such as Internet ticket purchase and travel information inquiry.

The operation layer 25 is used to provide rail transit operation services to users. According to the operation management level, it can be further divided into: a first-level operation center 252 and a second-level operation center 251.

The first-level operation center 252 is used to provide urban operation services and line operation services for city-level or line-level users; the second-level operation center 251 is used to integrate operational data of the first-level operation centers 252 to provide information to national users. National operational services.

Therefore, when the new line is put into use, it is not necessary to purchase hardware devices such as servers and storage, and it is not necessary to install various rail transit professional systems, and only need to open the corresponding account in the information system cloud platform, that is, the server and storage provided by the information system cloud platform can be used. Such as hardware equipment and professional systems such as AFC and PIS, thus saving the construction cost of the rail transit information system.

The second-level operation center 251 can integrate the operational data of the first-level operation center 252, thereby providing real-time data of the integrated cities and line operation centers to the national users, presenting the real-time appearance of all the lines to the national users, and providing statistical analysis.
