These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0070] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0071] First, the terms involved in this application are explained:

[0072] GIS server: refers to a computer system used to store, process and provide geospatial data and services. It is a key component in the GIS architecture and supports various GIS applications and services.

[0073] The multi-engine integration method provided in this application can be applied to Figure 1 The GIS architecture diagram is shown in the figure. Figure 1As shown in the figure, the GIS includes: data layer, application layer, client layer and protection layer. The data layer includes multiple databases such as PostGIS, Oracle Spatial and NoSQL. The application layer includes GIS server, application server, API, etc. The client layer includes desktop GIS, mobile GIS and Web GIS, etc.

[0074] Figure 2 A schematic diagram of an application scenario of the multi-engine integration method provided in this application, such as Figure 1 As shown, one application scenario of the prior art is: during the operation of the GIS architecture, the user enters an address query request in the Web GIS application, and the request is transmitted to the application server via the Internet. After receiving the request, the application server calls the map service and data service of the GIS server to perform address query and spatial analysis. The GIS server queries the relevant geographic data from the spatial database and generates a map service, and then returns the query result and the map service to the application server. The application server encapsulates the result as an API response and returns it to the Web GIS application. The final user receives the response in the Web GIS application, displays the query result and the map service, and can view and interact on the map.

[0075] The above-mentioned terminal equipment can be a wireless terminal or a wired terminal. The wireless terminal can be a device that provides voice and / or other business data connectivity to users, a handheld device with wireless connection function, or other processing equipment connected to a wireless modem. The wireless terminal can communicate with one or more core network devices via a radio access network (Radio Access Network, referred to as RAN). The wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal. For example, it can be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with the radio access network. For another example, the wireless terminal can also be a personal communication service (Personal Communication Service, referred to as PCS) phone, a cordless phone, a Session Initiation Protocol (Session Initiation Protocol, referred to as SIP) phone, a wireless local loop (Wireless Local Loop, referred to as WLL) station, a personal digital assistant (Personal Digital Assistant, referred to as PDA) and other devices. The wireless terminal may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, an access terminal, a user terminal, a user agent, a user device or user equipment, without limitation. Optionally, the terminal device may also be a smart watch, a tablet computer or other device.

[0076] Currently, existing GIS technology platforms all integrate a single GIS engine, which may not be powerful enough or lack flexibility in certain specific functions, limiting users' application in complex projects. Some engines may not be efficient in processing large-scale or complex spatial data, affecting the execution speed and effectiveness of the project. A single engine may be difficult to integrate seamlessly with other systems or data formats, limiting the ability to share data and collaborate with multiple systems. The licensing fees for some GIS software are high, and the licensing model may limit the scope of use and scalability of the software. Users who rely on a single supplier for update support and maintenance services may face the risk of service interruptions or untimely updates.

[0077] Combining the above scenarios, it can be seen that in the prior art, supporting GIS architecture operation through a single GIS has the technical problem of low GIS architecture access efficiency.

[0078] The multi-engine integration method provided in this application solves the technical problem of low access efficiency of GIS architecture by constructing an integrated GIS server including multiple GIS engines and then using the integrated GIS server to replace the GIS server in the existing GIS architecture.

[0079] A multi-engine integration method provided in an embodiment of the present application is intended to solve the above technical problems in the prior art and is executed by a multi-engine integration device.

[0080] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0081] It should be noted that the multi-engine integration method provided in the embodiment of the present application can be applied to the IoT device space architecture platform, wherein the IoT device space architecture platform is implemented based on an integrated GIS server. The IoT device space architecture platform includes an IoT data management platform, an IoT device management platform, an IoT big data integrated platform, and an engine library.

[0082] The IoT data management platform is used to connect massive devices by adapting the platform to the devices, and collect device data to the cloud; set up cloud APIs, and remotely control devices by calling cloud APIs.

[0083] The IoT device management platform is used to set up integrated city scenarios and classify and manage IoT devices for different integrated city scenarios.

[0084] The IoT big data comprehensive platform is used to register the comprehensive data of various IoT devices through a unified gateway connection, and then synchronize the transmission of uplink device information and recorded data and downlink control instructions with the IoT data management platform through various protocol networks, so as to conduct real-time and effective communication of data.

[0085] like Figure 3 As shown, Figure 3 A flowchart of a multi-engine integration method provided in an embodiment of the present application, a multi-engine integration method, may specifically include steps S201 to S205, wherein:

[0086] S201. Acquire multiple geographic information system servers, and construct an engine library based on the multiple geographic information system servers.

[0087] As geographic information is increasingly used, the demands for GIS technology in different industries and fields are becoming more and more diverse. A single GIS engine is often difficult to meet all needs, so it is particularly important to develop a platform that can integrate multiple GIS engines. By integrating multiple GIS engines, users can access specific functions of different engines on the same platform, avoiding the trouble of switching between multiple systems, improving work efficiency, and reducing the cost of purchasing multiple systems.

[0088] Specifically, multiple GIS service engines such as ArcGIS and Geo Server are obtained, and the engine server cluster is obtained by aggregating the multiple GIS service engines; the client of each GIS Server is independently deployed in the engine server cluster to obtain an engine library.

[0089] S202: Monitor status information of multiple geographic information system servers to complete maintenance and management of the multiple geographic information system servers.

[0090] In order to monitor the status information of multiple GIS servers and perform maintenance and management, a centralized monitoring system, such as Prometheus or Nagios, can be deployed. By regularly collecting key performance indicators (such as CPU usage, memory usage, disk space, network traffic, etc.) and service status (such as map service response time, database connection status, etc.) of each server and setting alarm rules, when an indicator exceeds the preset threshold, the system will automatically send an alarm notification. Administrators can perform troubleshooting and maintenance in a timely manner based on the alarm information to ensure the efficient and stable operation of the GIS server.

[0091] S203: Perform integration processing on multiple geographic information system servers to obtain a unified application programming interface, wherein the unified application programming interface is used to access multiple geographic information system servers.

[0092] Specifically, first deploy an API gateway or middle-tier service, which is responsible for receiving and parsing client requests; then, according to the request type and content, route the request to the corresponding GIS server for processing; after each GIS server completes the map service, data service or spatial analysis, it returns the result to the middle-tier service; the middle-tier service integrates and standardizes the data returned by different servers, and unifies the output format and protocol; finally, the middle-tier service returns the processing results to the client through a unified API, enabling developers to access and operate the functions of multiple GIS servers through a single interface.

[0093] S204: Create metadata for multiple geographic information system servers.

[0094] Specifically, define metadata standards and structures, and clarify the metadata attributes that need to be recorded, such as data source, data type, coordinate system, update time, etc.; develop or use existing metadata management tools to collect and record relevant information of data sets and services on each GIS server through automated scripts or manual input; store the collected metadata in a centrally managed metadata warehouse or database to ensure that it is queryable and maintainable; finally, provide a query interface or user interface so that administrators and users can easily retrieve and manage these metadata, thereby achieving a comprehensive understanding and efficient management of data and services on multiple GIS servers.

[0095] S205 , using the metadata as a dataset of the draft GIS service, creating a GIS service for each GIS server, and publishing the GIS service to the corresponding GIS server.

[0096] Using metadata as a draft GIS service dataset, creating a GIS service for each GIS server can include: first, extracting the metadata of each GIS server from the metadata repository as a draft dataset; then, using these metadata to define the configuration parameters of each GIS service, such as data source, layer, coordinate system, and service type; then, using automated deployment tools or scripts to create corresponding GIS services on each GIS server based on these configuration parameters, ensuring that the name, path, and function of the service are consistent with the metadata description; finally, testing and verifying the service to ensure that each created GIS service can run normally and meet the expected functional and performance requirements, thereby achieving efficient service creation and management based on metadata.

[0097] Publishing GIS services to the corresponding GIS servers can specifically include: preparing the necessary files and parameters of the services according to the predefined deployment configuration and metadata; uploading these service files and configurations to the corresponding GIS server through automated deployment tools or scripts; then, using the management interface or API of the GIS software (such as GeoServer, ArcGIS Server) on the server to register and publish these services, ensuring that the service path, access rights and parameters are set correctly; finally, testing and verifying the services to ensure that each published GIS service can be accessed and run normally and meet the expected functional and performance requirements, thereby achieving efficient service publishing and management.

[0098] The multi-engine integration method provided in the embodiment of the present application is used in a geographic information integration system, hereinafter referred to as an integrated system. Since different engines may perform well in different tasks, multiple geographic information system servers are obtained to determine multiple engines to be integrated, and then the multiple engines to be integrated are used to build an engine library, so as to make full use of the operating characteristics of each engine to optimize the performance of the integrated system, thereby improving the flexibility of the integrated system; by monitoring the status information of multiple engines in the engine library, the real-time status of each engine in the engine library is determined, and the maintenance and management of the above multiple engines are implemented based on the real-time status; the above multiple engines are integrated to obtain a unified application program interface that can access the above multiple engines, so as to realize the function of accessing multiple engines through one interface, and successfully establish a data transmission channel between the integrated system and a single engine; then metadata is created for the above multiple engines; the above metadata is used as a data set of a draft geographic information system service, so as to determine the data source for the operation of the integrated system; then a geographic information system service is created for each geographic information server to complete the deployment of the integrated system; finally, the deployed integrated system is published to the corresponding geographic information system server, and when there is a demand for geographic information services, users can call multiple engines through the geographic information system service, thereby achieving the beneficial effect of improving the access efficiency of the integrated system.

[0099] In an achievable manner, the above S203 performs integration processing on multiple geographic information system servers to obtain a unified application programming interface, which may specifically include S203-1 and S203-2, wherein:

[0100] S203-1. Obtain application programming interfaces of multiple geographic information system servers.

[0101] Specifically, access the documentation or management interface of each GIS server to obtain detailed information such as the API endpoints, request methods, parameters, and return formats it provides; then, use automated tools or scripts to collect and organize this API information in batches to ensure its structuring and standardization; then, store the collected API information in a centrally managed API document library or registration center for unified query and management; finally, provide developers with access and usage guides for these APIs through a unified interface or portal, so that they can easily call and integrate the functions of multiple GIS servers.

[0102] S203-2. Perform fusion processing according to the application programming interfaces of multiple geographic information system servers to generate a unified application programming interface.

[0103] Specifically, obtain the API endpoints, request methods, parameters, and return formats provided by each GIS server, and identify commonalities and differences; then, design a unified API specification to define standardized endpoints, parameters, and return formats; then, use an API gateway or middle-tier service to parse and convert client requests according to the unified specification, route them to the corresponding GIS server, and integrate the response data of each server; finally, provide services to the client through a unified API interface, so that developers can access and operate the functions of multiple GIS servers through a single standardized interface, thereby simplifying the development and integration process.

[0104] The multi-engine integration method provided in the embodiment of the present application connects and integrates through API and Python scripts, merges various GIS client services into API services that can be called by the platform, and enhances the service capabilities and flexibility of the platform.

[0105] In an implementable manner, the above S203-2 performs fusion processing according to the application programming interfaces of multiple geographic information system servers to generate a unified application programming interface, which may specifically include:

[0106] The adapter mode is used to integrate the application programming interfaces of multiple GIS servers to generate a unified application programming interface.

[0107] Create adapters for each GIS server API. These adapters are responsible for converting requests of the unified API specification into the specific API request format of the corresponding GIS server, and converting the server's response into a unified response format. Then, deploy an API gateway or middle-tier service to receive and process client requests through these adapters and route them to the corresponding GIS server. After receiving the server response, the adapter converts it into a unified format and returns it to the client. Finally, through this adapter pattern, seamless integration of different GIS server APIs is achieved, providing clients with a standardized and unified API interface, simplifying development and integration work, and using the adapter pattern to handle interface differences between different engines to ensure consistency and scalability of platform functions.

[0108] In one implementation, the status information includes a life cycle status and / or an operating status.

[0109] Accordingly, after the above S205 monitors the status information of the multiple GIS servers to complete the maintenance and management of the multiple GIS servers, it also includes S202-1 and S202-2, wherein:

[0110] S202-1. Monitor the life cycle status and / or operation status of multiple geographic information system servers.

[0111] Specifically, deploy a monitoring system, such as Prometheus, Nagios, or Zabbix, and regularly collect the key performance indicators and service status of the server through agents installed on each GIS server or through APIs. The key performance indicators include CPU usage, memory usage, disk space, network traffic, etc., and the service status includes service response time, error rate, etc.; then, aggregate these data to a centralized monitoring platform for real-time analysis and visualization; then, set alarm rules. When an indicator exceeds the preset threshold or an abnormality occurs, the system automatically sends an alarm notification to the administrator; finally, the administrator performs troubleshooting and maintenance based on the monitoring data and alarm information to ensure the efficient and stable operation of the GIS server.

[0112] S202-2. Determine whether to perform maintenance processing on multiple geographic information system servers based on the life cycle status and / or operation status.

[0113] Among them, maintenance processing includes the removal and processing of GIS clients.

[0114] The multi-engine integration method provided in the embodiment of the present application eliminates and processes GIS clients that are no longer online by monitoring the life cycle status of each engine and the operation status of the log monitoring engine, thereby achieving the beneficial effect of unified maintenance and management of the deployed GISServer engine by the platform.

[0115] In an implementable manner, the GIS service includes layer elements. Accordingly, after the above S205 uses the metadata as a dataset of the draft GIS service, creates a GIS service for each GIS server, and publishes the GIS service to the corresponding GIS server, it also includes S206 and S207, wherein:

[0116] S206: Create a layer element to be updated.

[0117] Specifically, determine the layer that needs to be updated and its element type, and obtain the metadata and existing element information of the current layer, where the element types include points, lines, surfaces, etc.; then, use geographic information system software or programming interfaces to create new layer elements, specify their geometry, attribute data, and style information, where geographic information system software includes ArcGIS API and GeoServer API; then, mark these newly created elements as pending update status and store them in a temporary data storage area or version control system; finally, through the verification and review process, ensure the accuracy and consistency of the new elements, and prepare to merge them into the existing layer for updating.

[0118] S207: Publish the layer elements to be updated to the corresponding geographic information system server.

[0119] Specifically, use GIS software or API to extract the layer elements to be updated from the temporary storage area or version control system, where APIs include ArcGIS API and GeoServer API; then, perform necessary data conversion and formatting to ensure that the new elements are compatible with the layer format and coordinate system of the target GIS server; then, upload and merge these new elements into the corresponding layer through API calls or management interfaces, and replace or add corresponding layer elements; finally, perform post-release verification and testing to ensure that the new elements are displayed correctly and function normally, thereby completing the update and release of the layer.

[0120] In an implementable manner, after the above S207 publishes the layer element to be updated to the corresponding geographic information system server, it also includes:

[0121] According to the geographic information system service, map rendering is performed to display the visualization interface corresponding to the geographic information system service.

[0122] First, obtain the required geographic data and layer information, including geometry, attribute data, and style configuration, through the GIS service API request; then, use the map rendering engine or library to parse and process this data and convert it into visualization elements; then, apply style and symbolization rules to render the map elements and set visual attributes such as color, line type, and annotation; finally, display the rendered map on a web page or application interface, providing interactive functions such as zooming, panning, and layer switching, so that users can intuitively browse and analyze geographic information.

[0123] In an implementable manner, the above S205, after using the metadata as a dataset of the draft GIS service, creating a GIS service for each GIS server, and publishing the GIS service to the corresponding GIS server, further includes S208 and S209, wherein:

[0124] S208. Determine whether there are any GIS servers that have been deactivated or are to be removed from the shelves based on the status information of the plurality of GIS servers.

[0125] First, the status information of each GIS server, such as operating status, performance indicators, error logs, and service availability, is regularly collected through the monitoring system or management interface. Then, the status information is analyzed to identify servers that are no longer responding, have severely degraded performance, or have been in a faulty state for a long time. Next, these abnormal servers are marked as disabled or to be removed from the shelves, and a report or alarm notification is generated to the system administrator. Finally, the administrator conducts further confirmation and processing based on the report and notification, and decides whether to execute the removal operation, thereby ensuring the stability of the system and the effective use of resources.

[0126] S209: If there are GIS servers that have been deactivated and / or are to be deactivated, a deactivation and / or destruction instruction is issued to the GIS servers that have been deactivated and / or are to be deactivated.

[0127] First, the system administrator confirms the GIS servers that need to be deactivated or destroyed through the management console, Ansible, Terraform and other automated operation and maintenance tools; then, the corresponding deactivation or destruction instructions are generated, which may include operations such as stopping services, releasing resource allocations, backing up data and deleting instances; then, these instructions are sent to the target GIS server or its management platform through API calls or script execution. The management platform can be the management interface of the cloud service provider; finally, the process and results of the instruction execution are monitored to ensure that the server is successfully deactivated or destroyed, and the system resources and status information are updated to reflect the latest server status.

[0128] The multi-engine integration method provided in the above embodiment is described below with reference to a specific example. Figure 4 As shown, the following steps are included:
