A microservice-based ats system

Abstract

The present invention provides an ATS system based on microservices, including: multiple front-end operating stations, API gateways, and multiple virtual machines in the cloud server, where a memory database is deployed in the cloud server; the background functions of the ATS system are split into multiple Separate microservices, all microservices run in multiple virtual machines on the cloud server and register service status with the memory database, each virtual machine runs one or more microservices and has a data adaptation layer; API gateway receives foreground operations The command sent by the station determines the microservice it belongs to and then sends it to the microservice; the microservice obtains the information required by the command in the memory database through the data adaptation layer and performs corresponding modification and processing, and then uploads the memory database update; the memory database is updated according to the currently registered microservice Push the modified and processed information to the microservice that subscribes to the information, so that when it recognizes that a command needs to be sent, it sends the command to the ground interlocking system. Simplify the work process, reduce work intensity, and reduce human input.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of rail transit, and in particular to an ATS system based on microservices. Background technique [0002] The automatic train monitoring system ATS system realizes the automatic supervision and control of the operation of the train in the rail transit management. Its main functions include: compiling the operation diagram, automatically handling the train route according to the operation diagram, automatically adjusting the train operation interval, and recording the operation data Wait. The traditional ATS system is divided into central ATS equipment and station ATS equipment according to the location. The central ATS equipment usually includes: (1) dispatching workstation: human-computer interaction interface, used to display the station map of the whole line and manually control signal trains; (2) Application server: generate daily plans, dispatch shifts, forward and maintain th...

Problems solved by technology

[0007] However, the existing traditional ATS system that allocates software functions according to the location of the hardware device has the following defects: 1. The software complexity is high. Take station extensions as an example, which integrates train number management, identification number tracking, operation adjustment, and automatic triggering There are multiple functional modules such as access routes, the software structure is complex, and the functions are interlocking; 2. The physical hardware location defines the scope of software jurisdiction. When the system expands, it can only rely on adding hardware devices to provide for the newly added station. However, the hardware cost is too high (including initial cost and subsequent maintenance cost). In order to improve reliability, redundant hot backup solutions are often adopted to reduce the impact of hardware failures. As redundant equipment is upgraded from dual-machine to Four machines, the complexity of the redundant hot standby judgment software is also doubled; 3. There are many identical processes inside each software, and the communication between the software relies on UDP (User Datagram Protocol) messages, and the data is transmitted at the first level. If the status of the station is transmitted from the station extension to the application server, and then from the application server to the dispatching server, there is a risk of delay and packet loss

Taking the processing process of the above two operations as an example, when a station extension in a centralized area has a hardware failure, it will lead to the failure of the car impounding and automatic triggering functions in the entire concentrated area, and there are many exchanges of information between station extensions in different concentrated areas. After the expansion of the line, it is necessary to increase the station extension hardware, and the cost will also increase
