Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.
As shown in fig. 1 to 2, a micro service architecture based grid search system includes:
the microservice registry: centralized management, invocation of services and commands, and storage of data information;
a service micro-service module: the micro service registration center is connected with the micro service registration center and is used for bearing or running sub services;
a search calling module: the micro service registration center is connected with the micro service registration center and used for searching data information or service and calling and displaying the searched information;
the micro-service management module: and the micro service registry is connected with the micro service registry and is used for monitoring and tracking data information or services.
The microservice architecture technology: the micro-service architecture develops small services into a micro-unit application form, runs by itself, and communicates by adopting a lightweight message mechanism. The microservice is built around business capabilities and deployed through a fully automatic deployment tool. These services can use different programming languages and different data storage technologies and ensure minimal centralized management.
The micro service architecture has a large number of services, so a uniform registration platform is needed for managing when the micro service architecture is constructed. After each micro-service instance is started, the instance information of the micro-service instance is registered to a service registry or a service registration center of the registration platform. In addition, if the caller of the service wants to obtain the service instance list, the caller needs to obtain the relevant information of the service from the service registry or the registry.
At present, by taking a mainstream registration platform of an internet micro-service architecture as a reference, a micro-service registration center suitable for a power grid enterprise is built in power grid regulation and control.
Of course, each instance of the micro-service is published and then discovered, and a discovery mechanism is required for one micro-service instance to be perceived by other calling service parties. The service instance list can be timely obtained through service discovery, and in a micro-service architecture, after a service instance is started, the position information of the service instance is put into a registry. And then the client side inquires from the service registry to obtain a corresponding service instance. In the process of selecting a single micro-service instance, the client requests a load balancing algorithm (polling or random) to select one from a plurality of service instances and then sends a request.
In this embodiment, the microservice registration center is further configured to acquire and store registration information and state information of the business microservice module.
In this embodiment, the service microserver module includes sub-service modules communicatively connected to each other.
In this embodiment, the search invoking module includes:
a word bank module: the system is used for collecting and storing phrase data and mapping phrases and corresponding services or data;
a search module: the word stock module is connected with the word stock module and used for acquiring the input word group, analyzing the word group and searching the data stored in the word stock module according to the analysis result;
a calling module: and the word bank module and the searching module are respectively connected and are used for displaying the data searched by the searching module and calling corresponding service or data according to the mapping relation.
In this embodiment, the micro service management module includes:
a service monitoring module: the micro service registry is used for monitoring the response made by the micro service registry and ensuring the operation safety of the micro service registry;
a service tracking module: the method is used for tracking the running state of the sub-service connected with the micro-service registration center and accelerating the response speed during calling.
A power grid searching method based on a micro-service architecture comprises the following steps:
acquiring parameter information of the sub-service;
storing the parameter information into a pre-constructed search model, and mapping the parameter information with the sub-service;
the searching model acquires input data and searches parameter information according to the input data;
and invoking the sub-service related to the input data according to the search result.
In this embodiment, the method for constructing the search model includes the following steps:
inputting phrase data;
carrying out correlation evaluation on the phrase data, and marking the phrase data;
mapping the data of the marked phrase with the corresponding sub-service or the parameter information of the sub-service;
storing the mapped phrase data into a phrase library;
building a search engine roughly begins to do two things:
1) establishing a quick and effective index through a crawler technology based on data;
2) and carrying out fair and accurate sequencing according to the data correlation.
The working principle of the network crawler is that the whole network is regarded as a tree structure, so that the initial data node represents a root node, the crawler program analyzes the initial data node from the root node, the data node is automatically extracted, and then the data node is continuously analyzed according to the data node.
The enterprise index creation technology generally adopts the inverted index technology, and the technology becomes a general standard in the field of search engines. For a document, the content therein consists of words. In order to quickly present document results to a user's search terms, we build a term-document storage structure. The inverted index is a specific storage form for realizing a word-document matrix. Through the inverted index, a document list containing the term can be quickly acquired according to the term. The inverted index is mainly composed of two parts: word dictionaries and inverted files. The word dictionary may be expanded according to industry needs. An inverted file is a list of files that the user wants to retrieve. The method comprises the steps of obtaining a batch of words by segmenting words of a user retrieval statement, finding documents to be retrieved by the user in an inverted file through the words, and sequencing the documents according to priority, wherein the priority of sequencing defines a sequencing algorithm according to various weights.
The related sorting uses TF-IDF algorithm, which is a common weighted sorting algorithm in information retrieval and data mining, and is used for evaluating the matching degree of a certain word to a file or data, and calculating a matching score. The TF-IDF core has two points: 1) if a word appears more frequently in the document, the more important the word is, the higher the score, i.e., TF; 2) if a term occurs in many documents, the lower the discriminative power of the term, the lower the score, i.e., the IDF.
In this embodiment, the parameter information of the sub-service includes registration information, running information, and status information of the sub-service.
In this embodiment, the phrase data is sorted according to the scores of the evaluations, and is labeled with a score.
In this embodiment, the search results are displayed in an order according to the evaluation score.
Combining the contents, based on various power grid service data, each instance service utilizes a search engine technology to create a data index file suitable for the instance service, and allocates search weight on the basis of tf-idf algorithm, and finally, all the instance services are registered in a service management center, and all the instance services can be called to obtain corresponding data through an integral calling frame;
based on the research of micro-services and search engines, the search engine with the micro-service architecture can be built, and a search engine named 'suo yuan' is built for the whole-year research in the Hunan power grid dispatching center on the basis of dispatching historical production management data and real-time production management data. The micro-service management framework is realized, data query services facing a service scene, such as report services, parameter query services, running data query services, micro-application services, document data retrieval services, intelligent reasoning services, power grid encyclopedia and the like, are provided, the system integrally follows the architecture concept of the micro-service, each service is small and fine, and the individual service managers operate the service operation factors such as processes, logics, data, logs and the like.
And in the aspect of establishing indexes, acquiring and integrating the professional application data through a crawler and a data acquisition tool, constructing a data index and a data authority, and regularly establishing an index file required by a single service according to business requirements. Through the above, after the integral construction is completed, the display of various means including character lists, data tables, graphs, geographic information and the like for the search results of various types of power grid service data is provided.
The technical scheme highlights the combination of actual power grid business and advanced internet technologies such as microservices and search engines, finds the basis of the theory and practice of establishing special hundredths for power grid enterprises, meets the construction requirements of power grid enterprise regulation and control departments in new generation construction, and guides other large, medium and small enterprises to construct intranet search directions.
It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
