When a certain service registration registry fails, the service registration function can be provided for the registries of other service nodes and the registries of other service nodes can register themselves, and the registries are mutually reserved because the registries of each service node realize the functions of the service terminal and the client terminal.
2) Service discovery is a core and basic component in a micro-service architecture, provides preconditions for mutual identification of various services, and provides specific network locations of service instances (i.e., single services, which may be a certain service of business services and public services) for other services to call.
3) And load balancing is realized, so that the number of objects processed by related services in the service layer is balanced. Specifically: load balancing is taken care of by specific components through standard interfaces.

The micro services herein include micro services in a single processing service among business services and communication services (TCP/IP communication micro services, serial communication micro services, etc.) among public services.
4) Service configuration, in a micro-service framework, the service configuration manages the configuration of all micro-services by a configuration center. The method and the device achieve complete separation of application configuration and application deployment. Centralized management, dynamic adjustment and automatic update of parameters required by each service running in a distributed environment are realized.

For example: for the information of the activation and handle positions (including the position of a steering handle, the position of a traction handle and the position of a brake handle) of a driving platform in the IO information of the vehicle, after the information is processed by the micro-service of the adaptation of the input signal of the vehicle and the micro-service of the processing of the input signal of the vehicle, the micro-service of the communication of the input signal of the vehicle is sent to a physical layer; for the speed information in the related information of the train, after being processed by the speed signal adaptation micro-service and the speed signal processing micro-service, the speed signal communication micro-service is sent to the entity layer; and for the wireless message, after the wireless message adaptation micro-service and the wireless message processing micro-service are processed, the wireless message communication micro-service is sent to the entity layer. The rest of the information is processed in a similar way, and is not described here again.
When the ATP function processing under the abnormal test condition is performed, fault simulation information is extracted from an application request through a fault information processing service, then the fault information processing service acquires relevant fault simulation information from an entity layer, and after the fault information adaptation micro-service and the fault information processing micro-service are used, the fault simulation information is transmitted to the ATP vehicle-mounted equipment through an access layer through a fault information communication micro-service.

The micro-service combination mode comprises two modes of arrangement and cooperation, wherein the arrangement mode adopts a central coordinator mode to coordinate the calling of a plurality of micro-services; collaborative means that all micro services collaborate with each other in a peer-to-peer fashion without the involvement of a central coordinator. The invention selects the service cooperation mode to realize the decentralization and independence of the micro service, and improves the reliability of the system.
Those skilled in the art will appreciate that a central coordinator resembles a central centralized controller through which service calls are coordinated. If it fails, normal call of service cannot be realized.
