Description

Technical Field

[0001] The present invention relates to the field of geographic information and cloud computing technology, and in particular to a method, system and device for constructing an Internet geographic information processing service chain. Background Art

[0002] For complex natural phenomena, a single model is difficult to summarize its physical mechanism. The processing process of geographic information is usually flexible and complex. A complete processing service requires the integration of multiple algorithms in series. According to the type, purpose, and quality of the processed data, it is also necessary to dynamically select and combine applicable processing algorithms at different processing stages. In the traditional field of geographic information, data processing algorithms are usually published and integrated on the same physical machine, and different physical machines cannot call each other's algorithms. That is, if the algorithm source code cannot be obtained and deployed on the local machine, specific processing cannot be performed. However, algorithms are usually developed by different people and are usually discretely distributed on different servers or physical machines, which makes it impossible to share algorithms and form algorithm islands.

[0003] With the development of network service technology and spatial information service concepts, geographic information data and processing functions are gradually shared and obtained through services in accordance with standard network service interfaces. The interoperability and collaborative processing of multi-source algorithms based on the Internet, the combination of different geographic information services, and the realization of a complete data processing system in series can effectively solve the problem of algorithm islands, so that heterogeneous codes located on different servers can be dynamically aggregated into a processing service chain for collaborative computing and automatic execution of many complex and high-density computing tasks.

[0004] The prior art discloses a geographic information web service integration method, which is used to integrate data services of different geographic information service platforms in a network environment. It uses a web integrated publishing server to directly connect to the server-side servers of different geographic information service platforms, transform the background services of different geographic information platforms, and use the calling interface of the web integrated publishing server to call the data of geographic information data services according to the platform type information and connection information of different platform products. At the same time, according to the data service standard predefined with the user's client browser, the geographic information service data converted into a unified format is provided to the user through the web service. The defect of this solution is that it only integrates data services in the Internet environment to improve the sharing and interoperability of data resources, but does not mention the sharing and collaborative computing of processing services and computing resources. Summary of the invention

[0005] One of the purposes of the present invention is to provide a method for building an Internet geographic information processing service chain to solve the algorithm island problem in the prior art; the second purpose is to provide an Internet geographic information processing service chain building system; the third purpose is to provide a computer device.

[0050] The processing service publishing module is used to register and publish services for geographic information processing algorithms, so that their information and calling methods are exposed on the Internet. According to the OGC network processing service specification, in order to fully describe an algorithm service, the algorithm service registration description rules are formulated, the algorithm description document is constructed using XML format documents, and the service description document is output according to the algorithm service registration description rules; the algorithm contributor is supported to describe, register and publish the algorithm according to the agreed description rules.

According to the load status of the sub-server where the atomic service is located, it selects the optimal service combination and generates an XML format file that can parse, execute and describe the entire front-end service chain.

[0061] (3) A complete business data processing logic is regarded as a workflow instance WorkflowInstance in the present invention, which is composed of multiple processing process instances ProcessInstance and their relationship Link. The specific conceptual model is as follows: Figure 3 shown.

[0062] On the service chain construction platform, based on the business logic and the functional description and status of the atomic service, drag the appropriate atomic services to form a service chain, and drag the input and output nodes connecting different atomic services to complete the configuration of the link relationship. This is considered to be the completion of the front-end service chain construction.
