Description

Technical Field

[0001] The present invention belongs to the technical field of rail transit cloud computing applications, and in particular relates to a visual arrangement system and method for urban rail transit cloud simulation test resources. Background Art

[0002] With the rapid development and continuous maturity of cloud computing and big data technologies, cloud platforms have been widely used in the rail transit industry, with multiple advantages such as resource sharing, data concentration, efficient operation and maintenance, energy conservation and environmental protection, personalized customization, cost reduction and efficiency improvement. As of June 2021, among the 44 cities that have opened urban rail transit, 29 cities have built, planned and implemented or are conducting cloud technology research. The deep integration of cloud computing technology and the rail industry has become an inevitable trend, and has become the foundation and driving force for building the digital transformation of the industry and promoting industry innovation and development. At present, the cloud application of cloud computing technology in the production system of the rail industry is still in its early stages. The subways in many cities in China have explored the product development model of deep integration of urban rail professional and cloud computing technology by building inspection and testing platforms.

[0003] Due to the particularity of the rail transit industry, there are basically few rail transit business systems deployed on the public cloud, and they are often carried in the form of private clouds. Therefore, the orchestration business provided by the traditional public cloud lacks the function of interconnection between the rail transit industry and the cloud, and it is difficult to fit with the rail transit industry. At present, most rail transit cloud platforms are mainly based on IaaS layer infrastructure services, lacking attention and support for the architecture and performance of cloud business systems. In particular, due to the large number of rail transit professions and complex system architectures, there are often situations where the system's acquisition front end is under the cloud and the management system is on the cloud. Therefore, when setting up the simulation test environment, it is necessary to allocate cloud resources and build a supporting environment under the cloud, which involves multiple links such as host, network, storage, and security, making it difficult to build the environment. In addition, there are often test requirements for interconnection of multiple professional interfaces between rail transit professional systems. Due to the limited resources of the test environment, complex scheduling is required during the test process to avoid the problem of repeated construction of the environment for business systems with many interconnected interfaces. In the process of urban rail cloud simulation testing, there is a lack of the function of repeatedly creating, destroying and restoring different cloud simulation environment scenarios based on limited simulation basic resources.

[0033] In a second aspect, the present application proposes a visual arrangement method of urban rail cloud simulation test resources, including a scene creation step, a template creation step and a template definition step;

[0034] The scene creation steps are:

[0035] Through the visual editing interface, drag and drop resource items, arrange the location and association of resource items, configure the attribute information required for resource items, and automatically generate and update template management data through the template management module after configuration is completed, and cache it in the storage management module. When the user completes the orchestration, perform deployment work through the visual editing interface. At this time, the scheduling engine module reads the template data and parses the data information of each resource in the template. At the same time, it verifies the status of the resources, lists the status of the resources to be created, modified or scheduled, and creates scenarios according to different resource status and resource types;

[0036] The template creation steps are:

[0037] Create templates on the visual editing interface.

[0044] Define output declaration: used to obtain resource information created by other templates or users;

[0045] Define resource declarations: Create infrastructure resources in the template, each with a unique type, name, and other configuration properties;

[0046] The scene destruction steps are:

[0047] The scene module to be destroyed is read through the visual editing module to start the scene destruction work. After starting, the scheduling engine module first reads the resource status involved in the storage management module and lists the resources to be destroyed. Then the cloud platform API is called to destroy the resources on the cloud, the corresponding network security interface is called to restore the original settings, the cloud system is shut down, the service of the simulation interface is simulated, and the results are captured in real time through the scheduling engine module during the destruction process, and the resource status in the storage management module is synchronously updated.

[0048] In some optional implementations of some embodiments, the scheduling engine module is also used to coordinate the dependencies and execution order between various resources, capture API return results, update resource status files, perform logging, and warn of problems in calling resource operation interfaces.

[0049] In a third aspect, the present application proposes an electronic device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps of the above method when executing the computer program.

Users can perform business system simulation testing on the scenario instance. This method can save the entire visually arranged simulation scenario as a template, or select a certain resource as a template to save. When needed in the subsequent simulation test process, the template file can be flexibly called, and the environment can be pulled up and deployed through the scheduling engine to solve the problem of limited resources in the test environment and improve the convenience and efficiency of cloud simulation environment scenario construction.

[0079] The parameter configuration unit is used to separate sensitive information and configuration parameters from the template code and perform dynamic parameter configuration when the template is applied.

[0080] Furthermore, the template management module is responsible for saving the templates created and edited by the visual editing module to the database, and providing users with template retrieval, version control, professional classification, sharing, and permission setting functions. A template refers to a text description file used to create and update scene instances in resource orchestration, which is used to describe the required cloud resources and service information.

[0081] The types of cloud resources supported by the template are not limited to the following: cloud computing resources (cloud hosts, bare metal), cloud storage resources (cloud hard disks, object storage), cloud network resources (classic networks, VPCs, subnets, routers), and cloud security resources (virtual firewalls, security groups).

When applying the template, variables can be dynamically configured to improve the flexibility and security of the template.

[0085] Through the template management function based on the rail transit simulation test scenario provided by the present invention, the template parameters can be used to declare the required cloud platform resource types, specification configurations, and the relationship between resources; can be used to declare the required cloud edge / cloud system resource types, parameter configurations, interface configurations, and the relationship between resources; can be used to declare the interface / system resource types, parameter configurations, interface configurations, and the relationship between resources of the simulation tool.

[0086] The scheduling engine module is used to parse the template to obtain template parameters, and to build corresponding types of business scenarios with the cloud platform, the cloud device and the simulation interface according to the parsed template parameters.

[0087] In some optional implementations of some embodiments, the scheduling engine module includes an on-cloud resource scheduling unit, an off-cloud resource scheduling unit, and a simulation device scheduling unit;

[0088] The cloud resource scheduling unit is used to call the cloud platform API interface to create a new virtual machine when the resource type in the parsed template parameter is a cloud resource and the resource item construction status is a new type; when the resource item construction status is an existing type, schedule the existing virtual machine environment, and finally configure the corresponding network and security parameters according to the network and security status of the resource item;

[0091] Furthermore, the scheduling engine module can parse the template parameters and classify the scene building according to the parsed template parameters, and query the storage management module to verify whether the building type in the template already exists, and mark the building status.

[0092] 1) When the resource type in the template parameter parsed by the cloud resource scheduling unit is a cloud resource, and when the resource item construction status is a new type, the scheduling engine module calls the cloud platform API interface to create a new virtual machine; when the resource item construction status is an existing type, it schedules the existing virtual machine environment. Finally, configure the corresponding network and security parameters according to the network and security status of the resource item.

[0093] 2) When the resource type in the template parameter parsed by the off-cloud resource scheduling unit is an off-cloud resource, the boundary network devices and boundary security devices at the edge of the cloud are scheduled for API docking scheduling, opening up the network and security links between the cloud and off-cloud, and realizing the interface connectivity between the business system in the on-cloud virtual machine and the off-cloud system.

[0094] 3) When the resource type in the template parameter parsed by the simulation device scheduling unit is a simulation type, the simulation system and the corresponding network and security devices are scheduled to provide a simulated business interface or data interface for the business system in the virtual machine on the cloud.

[0095] The scheduling function based on the rail transit simulation test scenario template provided by the present invention can be used to create scenario instances. The scheduling engine module can parse the template parameters and perform scenario construction scheduling according to the parsed template parameters. It can be API-connected with the cloud platform to create a new virtual machine environment, or schedule an existing virtual machine environment, including but not limited to the virtualized computing resources, storage resources, network resources, and security resources of the cloud platform. It can be API-connected and scheduled with the boundary network devices and boundary security devices at the edge of the cloud to connect the network and security links between the cloud and the cloud, and realize the interface connectivity between the business system in the cloud virtual machine and the system under the cloud.

[0100] The resource data management unit is used to record resource item configuration data, including resource item configuration information of the cloud platform, cloud devices, and simulation interfaces. When resources change, resource data records also need to be updated synchronously. Resource data is finally saved in the database and provided to the visual editing module for display, and sent to the scheduling engine module for query verification;

[0101] The log data management unit is used to record system logs, operation logs and running logs.

[0102] In a second aspect, the present application proposes a visual arrangement method of urban rail cloud simulation test resources, including a scene creation step, a template creation step and a template definition step;

[0103] The scene creation steps are:

[0104] Through the visual editing interface, drag and drop resource items, arrange the location and association of resource items, configure the attribute information required for resource items, and automatically generate and update template management data through the template management module after configuration is completed, and cache it in the storage management module. When the user completes the orchestration, perform deployment work through the visual editing interface. At this time, the scheduling engine module reads the template data and parses the data information of each resource in the template. At the same time, it verifies the status of the resources, lists the status of the resources to be created, modified or scheduled, and creates scenarios according to different resource status and resource types;

[0105] Furthermore, the user can drag and drop resource items through a visual editing interface, arrange the positions and associations of resource items, and configure the required attribute information of resource items.

[0106] The template management module automatically generates and updates template management data according to user operations, and caches the data in the storage management module.

[0107] When the user completes the orchestration, the deployment work can be performed through the visual editing interface. At this time, the scheduling engine module reads the template data, parses the data information of each resource in the template, verifies the status of the resources, and lists the status of the resources to be created, modified or scheduled.

[0108] When the cloud resource type is in the new state, the scheduling engine module calls the cloud platform API interface to create a new virtual machine; when the resource item construction state is an existing type, the existing virtual machine environment is scheduled. Finally, the corresponding network and security parameters are configured according to the network and security status of the resource item.

[0109] When the resource type under the cloud is in the newly created state, the scheduling engine module calls the API interface of the boundary network device and boundary security device at the edge of the cloud to open up the network and security links between the cloud and the under-cloud, and realize the connection between the business system in the virtual machine on the cloud and the system interface under the cloud.

[0110] When simulating interfaces or system types, schedule the simulation system and corresponding network and security devices to provide simulated business interfaces or data interfaces for the business systems in the virtual machines on the cloud.

[0111] The template creation steps are:

[0112] Create templates on the visual editing interface. The visual editing interface reads resource item configuration content, displays dragged resource items according to resource item classification and definition, obtains metadata information of resource item attributes according to resource item configuration, dynamically loads attributes and corresponding attribute configurations, handles dependencies between attributes, ensures that the combination of attribute values ​​is logical, provides detailed descriptions of attributes and filling prompts, configures attributes in a variable manner, separates sensitive information and fixed values ​​from template code, and ensures template security and flexibility;

[0113] After the resource item configuration and attribute configuration are completed, the resource items are connected to determine the dependency relationship between resource items, and the execution engine is guided to analyze the sequence of resource creation and connect them reasonably;

[0114] After the connection is completed, the template content is serialized in JSON format and sent to the template management module for template storage. Different templates are established according to business divisions, or different versions are created under one template to achieve template creation;

[0115] Furthermore, the user creates a template on the visual editing interface. The visual editor reads the resource item configuration content, and displays the resource items that the user can drag and drop according to the resource item classification and definition. Resource items include cloud resources, including virtual computing resources, virtual network resources, virtual storage resources, and virtual security resources; resource items include cloud resources, including cloud boundary network devices, cloud boundary security devices, cloud boundary interface devices, etc., cloud devices or systems under the tested major or related majors; resource items include virtual interfaces or virtual systems of simulation tools; resource items include test scenarios of other majors, including interface docking systems, devices or services, etc.

[0116] Based on the resource item configuration, the visual editor can obtain the metadata information of the resource item attributes, including field type, parameter range, whether it is required, etc., dynamically load attributes and corresponding attribute configurations, handle the dependencies between attributes, ensure that the combination of attribute values ​​is logical, and provide detailed descriptions and filling tips of the attributes to help users understand the meaning of each attribute. Users can configure attributes in a variable manner, separate sensitive information and fixed values ​​from the template code, and improve template security and flexibility.

[0117] Users can connect resource items and determine the dependencies between them, which can guide the execution engine to analyze the order of resource creation and connect them properly.

[0118] Visual editing reads available values ​​of resource attributes, such as specifications, images, and availability zones, through the storage management module to ensure the validity of attribute values.

[0119] After the visual editor finishes editing the template, the template content is serialized in JSON format and handed over to the template management module to save the template.

[0120] Users can create different templates according to business divisions, or create different versions under one template to modify and upgrade a business environment.

[0121] The template definition steps are:

[0124] Define variable declarations: Introduce external inputs in templates to increase the flexibility and reusability of templates, including custom configurations when applying the template;

[0125] Define output declaration: used to obtain resource information created by other templates or users;

[0126] Define resource declarations: Create infrastructure resources in the template, each with a unique type, name, and other configuration properties;

[0127] Furthermore, the template structure consists of four parts, which are configuration declaration, resource declaration, variable declaration, and output declaration in order.

[0128] Configuration declarations are used to specify the cloud service provider or infrastructure platform to be used. This includes configuring connection parameters, authentication information, region, etc.

[0129] Variable declarations are used to introduce external inputs into templates to increase the flexibility and reusability of templates, allowing users to customize configurations when applying templates.

[0130] Output declarations are used by other templates or users to obtain information about the created resources.

[0131] Resource declarations In a template, you can define the infrastructure resources to be created, such as virtual machines, storage buckets, database instances, network rules, etc. Each resource has a unique type and name, as well as other configuration properties.
