Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the accompanying drawings in combination with the embodiments. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
A first aspect of the present invention provides a relay protection fault information system based on springclosed micro-service, as shown in fig. 3, including: the system comprises a relay protection fault information main station, a plurality of relay protection fault information substations and a service registration center; the relay protection fault information master station comprises a plurality of spring closed micro servers, and the spring closed micro servers register services with the service registration center respectively to form a service list; the relay protection fault information substation is provided with a Ribbon service consumer interface and is connected with the service registration center according to a request to acquire the service list; and the service registration center records the cluster metadata information according to the configured springclosed micro server, generates a service list and provides the service list to a Ribbon service consumer interface according to a request. Therefore, the system provided by the invention is a brand-new solution for realizing load balancing by closely combining with the relay protection fault information system, mainly adopts a spring group micro-service framework, solves the load balancing situation of the relay protection fault information system, improves the utilization rate of the server, and provides effective guarantee for the stability and reliability of the system. The system framework adopts a spring Cloud Ribbon component of spring Cloud micro-service, the spring Cloud Ribbon is a load balancer of a client, and the load balancing of the relay protection fault information system is realized by using an eureka registration center.
As shown in fig. 3, microservice 1, microservice 2, and microservice 3 are a service cluster, and they all register services with a service registry, and each service is a server and can support configuration of multiple servers; the registration center records cluster metadata information according to the configured micro service; by installing a Ribbon-based component on the substation server, an Eureka registration center can obtain a service list after registration, when the substation needs to push a fault state and a relay protection action upwards, the Ribbon-based server firstly receives a request, and selects service resources for calling through a relevant balance strategy from the service list again, so that the idle of the resources is avoided; when 1 or more servers in the service cluster are down, the rest servers without being down can take over the service of the (down servers) and continue to use, so that the stable operation of the system is ensured.
As shown in fig. 4, the substation server has a plurality of service processes, including a service process of a protection action, a service process of a protection alarm, a service process of a fault state (including a switching value displacement, a communication state, and an operating state), and a service process of calling attributes of a protection/recording device (including a calling and sending function of a fixed value, a soft pressing plate, a fixed value area code, a switching value, an analog quantity, and a recording file); after the request message sent by each process of the substation is subjected to secure encryption by base64, a micro server is selected through a Ribbon service consumption interface registration mechanism. Ribbon mainly eliminates the worst service by reasonably using iRule (rule mode), picks out the service with the least concurrency and the shortest response time, and selects the proper service according to the request quantity limit of protection action/protection alarm/fault state/call and the current active connection number of each process. The service state serverStats mainly has the functions of judging connection abnormity, connection overtime abnormity and network abnormity. Ribbon obtains a list of the Eureka registration center to the service end through a Server list updating service, then judges that the micro Server has spare services according to a built-in load balancing algorithm, and achieves the effect of load balancing through polling access.

Specifically, the example is registered with a Eureka service registration center when the springclosed micro server is started, the Eureka puts the registration information of the springclosed micro server into a memory, and defaults to perform heartbeat detection on a service provider every 30 seconds, and if the heartbeat detection exceeds 30 seconds, the service provider is considered to be down, and the registration information in the memory is deleted. And the service consumer side, namely the substation, acquires the registration information from the Eureka Server through a Ribbon service consumer interface, stores the registration information into a local memory, and communicates with the springclosed micro Server through the registration information.

inquiring a service list in a polling mode, and eliminating the down micro server;
performing a filtering service;
judging whether the service request of a micro server exceeds a threshold value within a preset time interval (for example, within 30 s), if so, returning to the polling step, otherwise, entering the next step; specifically, the (action/alarm/call/fault state) time interval/threshold may be configurable;
