Description

Technical Field

[0001] The present invention relates to the technical field of computer simulation, and more particularly to a situation display method and device driven by simulation data. Background Art

[0002] The simulation platform is a series of simulation support tools with the simulation engine as the core, including model construction, resource management, data management, distributed operation, simulation calculation, data analysis and other functions, which can provide extended services for simulation deduction; the simulation engine is responsible for calculating and advancing the core components of the simulation, has a time synchronization function, can schedule the simulation model in the same time period according to the simulation scenario, execute the calculation logic in the model, and generate simulation data; the simulation scenario is a file that records the simulation conditions, simulation environment, simulation entity type, quantity, configuration parameters and other information of the simulation deduction, which is the script of the simulation deduction, referred to as the scenario; the simulation model is used to simulate the system behavior and Mathematical functions of dynamic characteristics can be used by computers to deduce the behavior of the object under different conditions at different times; the simulation cycle is the time required for a simulation calculation of all models; the situation display is a visualization system used to present all relevant information in a specific field, which can display complex information and data to help decision makers quickly understand the current situation or changes in the environment; situation resources are used to present entities, special effects and interfaces of situation information, among which situation entities are three-dimensional models of cars and ships, situation special effects are dynamic effects such as communication and detection, and situation interface is the human-computer interface for information and data display; the rendering cycle is the time required for the computer to complete a situation display screen calculation to the output screen.

[0003] At present, there are two problems in the existing situation display method:

[0004] First, different simulation platforms have different definitions of simulation data, and parameters with the same meaning also have different definitions in naming. For example, the longitude of the geographic coordinate system is defined as longitude on some simulation platforms and lon on others. The situation display system receives simulation data and needs to parse the data according to the simulation platform data specifications before it can complete the driven display of the situation. Therefore, the situation display system is generally deeply bound to the simulation platform and cannot quickly adapt to new simulation platforms, and its flexibility is not high. Second, the simulation platform usually has a high computing frequency (greater than 100 frames per second) and can generate a large amount of simulation data, while the rendering engine rendering frequency is related to the display refresh rate (usually 60 frames per second). If the simulation data is processed and driven every time, the rendering engine cannot complete data processing and rendering in real time, resulting in the situation display content and simulation results being out of sync, causing delays.

[0005] Therefore, how to quickly adapt the situation display to different simulation platforms to enhance system flexibility, and how to ensure that the situation display content is synchronized with the simulation results to eliminate delays are issues that technical personnel in this field urgently need to solve.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] The embodiment of the present invention discloses a situation display method based on simulation data drive, such as Figure 1 , including the following steps:

[0049] S1. Based on the output parameters and system parameters of situation display of different simulation platforms, configure the interface mapping relationship between simulation data and situation data to form a situation configuration file, so as to facilitate dynamic query of data interface mapping relationship according to resource requirements under different assumptions and reduce resource consumption;

[0050] S2. Establish network communication connection, divide the simulation data into corresponding data transmission channels and interfaces according to the situation display requirements of situation entities, situation effects and situation interfaces, and ensure that the simulation data can be received and processed efficiently and in real time;

[0051] S3 receives simulation data, simulation data including initialization data, resource creation data, resource update data and resource destruction data, according to the type of simulation data corresponding to the simulation situation initialization, simulation situation resource creation, simulation situation resource update and simulation situation resource destruction;

[0052] S4. Repeat the process of creating, updating and destroying simulation situation resources to realize the situation process demonstration driven by simulation data, until the simulation ends, clear the simulation situation resources, and wait for the next simulation situation display.

[0053] In order to further implement the above technical solution, Figure 2 The specific contents of step S1 include:

[0054] Step 11. Traverse the simulation engine parameters and simulation model types involved in the situation display from the simulation platform, and record the engine parameter Ep under the simulation engine E i and simulation model list M i The model parameter Mp under i ;

[0055] Step 12. Traverse the situation entities, situation effects, and situation interfaces involved in the situation display from the situation display system, and record the situation entity SM i The entity parameter SMp under i , special effect parameters SEp under situation special effect SEi i and Situation Interface SIi Interface parameters SIp i ;

[0056] Step 13. Configure the mapping relationship between simulation platform parameters and situation display system parameters: traversal engine parameter Ep i and model parameter Mp i , from the entity parameter SMp i , Special Effect Parameters SEP i Or interface parameter SIp i Select the corresponding parameters for configuration, form a mapping relationship between simulation platform parameters and situation display system parameters, and generate a situation configuration file;

[0057] Among them, model parameters and engine parameters can be configured to multiple entity parameters, special effect parameters and interface parameters, while entity parameters, special effect parameters and interface parameters are only allowed to select one configuration from model parameters, engine parameters or default values.

[0058] In order to further implement the above technical solution, the situation configuration file is used to describe the association relationship between the simulation platform and the situation display system, wherein the array records the parameter mapping relationship between the current simulation and the situation, and each element represents a set of parameter mapping relationships. Each sub-element in the element records the parameters required for the entity, special effect, and interface and the corresponding parameters of the required parameters in the simulation engine or model, wherein ${target parameters} represent the parameters required for the entity, special effect, and interface, and ${source parameters} represent the corresponding parameters of the required parameters in the simulation engine or model.

[0059] In order to further implement the above technical solution, in step S2, the data transmission channel and interface of the simulation data are classified according to the sending frequency of the simulation data and the data processing priority, and are respectively classified into four categories: high frequency high priority, high frequency low priority, low frequency high priority, and low frequency low priority. Among them, high frequency means that data is received in each situation rendering cycle, low frequency means that data is received at intervals of multiple rendering cycles, high priority means that data is updated in the current situation cycle, and low priority means that data is updated in the next situation cycle;

[0060] Specifically: For high-frequency and high-priority data such as situation entities, special effects, and interface updates, each type of data is transmitted using a separate data channel to ensure that the data can be updated as soon as possible and will not be blocked by other data. For low-frequency and high-priority data such as situation event updates, a core channel can be used for data transmission. The data type field is used to dynamically parse the data to obtain the corresponding parameters, reducing data channel resource consumption. For high-frequency, low-priority data such as situation logs and charts, and low-frequency, low-priority data such as simulation platform status, a single data channel and multiple caches can be used for transmission. Different types of data are stored in the corresponding cache after parsing. After the system has processed other tasks, the data is read from the cache for update.

[0065] Destruction of simulation situation resources: Simulation situation resources are centrally managed by the resource manager. The destruction of resources is completed from the resource manager, and then the resource list information of the data manager is updated.

[0066] In order to further implement the above technical solution, the specific contents of the simulation situation initialization include:

[0067] Configure scene display parameters and load scenario resources according to scene data;

[0068] According to the situation display element list, query the situation configuration file and configure the mapping relationship between the situation data and simulation data in the data manager;

[0069] The resource manager preloads situation entities, special effects, and interface resources according to the situation display element list.

[0070] In order to further implement the above technical solution, the simulation situation resource update is adapted to different simulation frequencies, and the problem of the update frequency of the simulation platform and the rendering frequency of the situation display system being out of sync is solved through the situation data manager. At the same time, the data usage frequency can be dynamically adjusted according to the update requirements of different types of data;

[0072] The real-time data RD of the simulation platform is sent asynchronously to the situation display system through network communication in each simulation cycle. The real-time data manager of the situation data manager receives the data RD and stores it in the real-time data RD in a way of overwriting the previous data according to the data type. i , get the real-time data list RD n ;

[0073] The event data SD of the simulation platform is sent to the situation display system asynchronously through network communication in a certain simulation cycle. The event data manager of the situation data manager receives the data SD and stores it in the data queue SD in a queue according to the data type. i , get the event data list SD n ;
