Description

Technical Field

[0001] The present invention relates to the field of shipbuilding digitization, and in particular to a replay and display control method based on event tracing. Background Art

[0002] In the field of modern simulation and deduction, replay and display control technology is widely used in military training, accident analysis, sports training and other scenarios. This technology can record, store, process and replay data of specific events or processes, providing users with a comprehensive platform for repeated viewing, analysis and learning.

[0003] At present, the core functions of replay technology include the following aspects:

[0004] Event recording and replay: The replay system can record events that occurred during the simulation and reproduce these events during playback, helping users analyze key moments in the simulation.

[0005] Situation display: During the playback process, the system can display relevant situation diagrams, including the status of participants, the progress of tasks, and the interactive relationship between the two parties.

[0006] User interaction: Users can control the playback process by operating the playback progress (such as pause, speed, rewind, etc.) and conduct detailed analysis of the playback according to their own needs.

[0007] However, the existing replay technology has the following major problems and shortcomings:

[0008] Insufficient event screening and analysis: Most existing replay systems can only display events linearly based on a timeline, lacking effective event screening and classification mechanisms, making it difficult for users to quickly locate key events in large-scale deduction data. This limitation often requires users to manually search for periods of interest when analyzing deductions, affecting analysis efficiency.

[0009] Lack of situation backtracking function: Although the existing system supports playback and situation display, it lacks the function of situation backtracking for specific events. For example, during the simulation, if the user wants to view the detailed situation information when a certain command decision event occurs, the existing system cannot provide such a deep backtracking function at a specific time point, and the user cannot easily trace the cause and effect of the event.

[0010] Insufficient multi-branch deduction capabilities: In many practical application scenarios, users need to explore deduction paths under different conditions to analyze the effects of different strategies. However, existing replay systems can often only replay along a single event development path, and cannot provide multi-branch deduction and comparative analysis of different decision paths, limiting users' ability to analyze and evaluate complex scenarios.

[0011] User interaction is not intelligent enough: The user interaction function of the existing system is usually limited to the basic operation of controlling playback, lacking the intelligent push function for key events. Users need to manually operate to view specific events in the simulation, and it is difficult to obtain key information of interest in a timely manner according to personal needs. This limitation of interaction reduces the user experience.

[0012] Limited data correlation analysis capabilities: Although existing systems can record and display events during the simulation process, most of them cannot conduct in-depth correlation analysis of these events with other simulation data (such as mission status, personnel actions, communication links, etc.). It is difficult for users to view the correlation between events through multi-dimensional analysis methods, which limits the overall understanding of the complex simulation environment.

[0013] In general, the existing replay system has many deficiencies in event analysis, situation backtracking, multi-branch deduction, intelligent interaction and data correlation analysis, and it is difficult to meet the requirements of analysis depth and efficiency in complex simulation deduction scenarios. These problems need to be solved urgently to improve the application effect of the replay system in simulation deduction.

[0014] To this end, we designed a replay and display control method based on event tracing to solve the above problems. Summary of the invention

[0015] The purpose of the present invention is to provide a playback and display control method based on event tracing to address the deficiencies of the prior art and to solve the problems raised in the background technology.

[0016] To achieve the above object, the present invention provides the following technical solutions:

[0017] A playback and display control method based on event tracing includes the following steps:

[0018] Enter key events: Through user input or automatic system determination, important events in the simulation process are marked as key events. Key events include but are not limited to command decisions, mission completion, target discovery, target assessment, and damage events.

[0019] Event data analysis: Analyze and process the key events entered, and associate them with the data in the simulation process to form a mapping relationship between events and data;

[0020] Dynamic display of key events: During the simulation playback process, key events are displayed in real time, allowing users to dynamically obtain relevant information during the playback process and filter and display them according to the timeline or category of the event;

[0021] Game situation review: During the replay process, the game situation review is performed based on the key events selected by the user, and the command decision, red / blue team situation, and personnel status information related to the event are displayed;

[0022] Playback control: Provides playback control function, allowing users to start, pause, speed up, and end the playback process, and flexibly adjust the rhythm and display method of the playback process;

[0023] Key event subscription and push: Users can choose to subscribe to specific key events. The system will push key event results in real time based on the user's subscription content during the simulation process. The push content includes the time point of the event, the nature of the event, and its impact on the simulation situation;

[0024] Evaluation result tracing: Based on the evaluation results of simulation data, key events in the simulation process are traced, and the impact of key events on the task completion status, command decision-making efficiency, target damage effect, etc. are analyzed, supporting the visualization of evaluation results;

[0025] Simulation data correlation analysis: During the simulation process, the system associates key events with simulation data and supports multi-dimensional data analysis functions. Users can conduct in-depth analysis of simulation situations based on dimensions such as tasks, personnel status, and communication relationships.

[0026] As a preferred technical solution of the present invention, the key event entry step supports filtering of key events of specific types based on user-defined subscription conditions, including but not limited to mission completion, target damage and command decision events.

[0027] As a preferred technical solution of the present invention, the event data analysis step uses the event timeline and the simulation data set to perform event correlation analysis, and supports cross-comparison of task status and personnel status.

[0028] As a preferred technical solution of the present invention, the key event dynamic display step can display events in real time through a graphical user interface, and supports users to dynamically adjust the display content by filtering timelines, categories and task status.

[0029] As a preferred technical solution of the present invention, the deduction situation backtracking step supports multi-level situation backtracking by selecting key events, including backtracking display of personnel status, communication relations, and command decision-making chain.

[0030] As a preferred technical solution of the present invention, the key event subscription and push steps support real-time sending of event reminders during the simulation process, and the push content includes the occurrence time of the key event, the event type and the corresponding simulation data impact.

[0031] As a preferred technical solution of the present invention, the evaluation result tracing step visualizes the evaluation results by establishing an indicator tracing mechanism, and traces back the task execution effects in the simulation based on key events.

[0032] As a preferred technical solution of the present invention, the deduction data association analysis step establishes an association model to cross-compare and analyze data such as task status, personnel status, communication relationships and command decisions, thereby supporting multi-dimensional situation deduction results display.

[0033] As a preferred technical solution of the present invention, it supports customized display of key events based on user needs during the review and playback process, and provides event screening functions based on timeline, task category, and personnel status in multiple dimensions.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. The present invention significantly improves the event analysis capability in the simulation process by introducing an autonomous determination and dynamic display mechanism for key events. Users can enter key events automatically or manually, and the system can analyze and dynamically display these events in real time. During the playback process, it supports the situation backtracking function, allowing users to backtrack to a specific moment based on key events and view multi-dimensional information such as personnel status, command decisions, and communication links at that time, greatly improving the analysis efficiency and accuracy of complex scenarios.

[0036] 2. The present invention also provides a multi-branch deduction function and a subscription push mechanism for key events, so that users can perform multi-path analysis on the deduction process based on different task assumptions. The system supports real-time push of subscribed key events during the deduction process, helping users to obtain information of interest in a timely manner. At the same time, the correlation analysis function of deduction data enables users to examine the correlation between events from multiple dimensions, improving the in-depth understanding of simulation results and decision support capabilities. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Figure 1 This is a flowchart of a playback and display control method based on event tracing proposed by the present invention. DETAILED DESCRIPTION

[0038] 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.

[0039] The following is combined with Figure 1With reference to the accompanying drawings and a number of embodiments, specific embodiments of the present invention are described in detail.

[0040] Example 1: Entry and management of key events

[0041] This embodiment 1 relates to the entry and management of key events in a playback and display control method based on event tracing.

[0042] Key event entry: The system determines the key events in the simulation through manual entry by the user or automatic recognition mechanism. Key events include but are not limited to the following types:

[0043] Command decision events: such as strategic or tactical orders issued by commanders.

[0044] Task completion event: For example, a task objective is successfully achieved.

[0045] Target discovery event: For example, a reconnaissance system discovers an enemy target for the first time.

[0046] Damage event: For example, an attack causes damage to an enemy target.

[0047] Communication interruption event: The communication link is interrupted or fails.

[0048] Event association and classification: The system classifies and associates the entered events, and ensures the accurate association between key events and simulation data through the mapping relationship between timelines and tasks. For example, the association between the time point when the commander issues a task and the time point when the task is completed can be used to analyze the efficiency of task execution. The system improves the accuracy of event analysis by associating events in different dimensions such as task status, personnel status, and communication status.

[0049] Optimization of event entry mechanism: To improve the efficiency of the system, the system can automatically identify specific types of events from the simulation process. For example, when the system detects that a commander issues an important order, it can automatically mark the event as a "command decision event" and record the time, place and execution of the order.

[0050] Example 2: Dynamic display and situation review based on key events

[0051] This embodiment 2 involves dynamic display and situation backtracking functions based on key events.

[0052] Dynamic display: During the replay process, the system can display key events in real time on the graphical user interface (GUI), and users can select different event types for display and filtering. For example, users can choose to view only "target discovery events", and the system will highlight the time point of target discovery on the playback timeline and display detailed discovery locations, target properties, etc.

[0053] Situation Backtracking: During playback, users can backtrack based on a key event. For example, users can click on a command decision event, and the system will backtrack to the overall situation when the decision event occurred, displaying information such as the red / blue force deployment, personnel status, and communication relationships at the time, to help users analyze the impact of the decision. The backtracking function not only displays the current situation, but can also be further refined to the specific action routes of the red / blue side, changes in the command chain, etc.

[0054] Situation filtering display: In order to enhance the user's operating experience, the system allows users to filter and display the playback process based on different dimensions of events (such as task status, communication link, personnel status, etc.). For example, users can choose to view only events with interrupted communication status, and hide other information not related to communication through the filtering display function to improve analysis efficiency.

[0055] Example 3: Playback Control and Multi-branch Deduction

[0056] This embodiment 3 introduces playback control and multi-branch deduction.

[0057] Playback control function: Users can operate the playback process through the control interface during playback, including start, pause, speed play and rewind operations. For example, when analyzing the completion efficiency of a key task, users can quickly skip irrelevant parts through speed playback and focus on the time period when the key event occurred. At the same time, users can use the rewind function to return to the time point before any key event for re-analysis.

[0058] Multi-branch deduction: The system supports the function of multi-branch deduction, which creates different deduction paths through different assumptions. For example, the system can perform different branch deductions on the execution effect of the task based on the different decision paths of the Red Army. Through this multi-branch deduction, users can compare the deduction results under different decisions, so as to obtain a more comprehensive analysis. For example, in a simulated battle, the Red Army commander can choose different offensive strategies. The system can deduce the possible results of each strategy separately and show its impact on the completion of the task.

[0059] Example 4: Subscription and real-time push of key events

[0060] This embodiment 4 introduces the subscription and real-time push functions of key events.

[0061] Key event subscription: The system allows users to subscribe to specific types of key events based on their own analysis needs. For example, military commanders can choose to subscribe to "mission completion events" and "target damage events". During the simulation process, the system will automatically monitor the occurrence of such events and push real-time notifications to users when events occur.

[0062] Event push mechanism: During the simulation process, the system sends notifications to users who have subscribed to specific key events through the real-time push function. The push content includes the time, location, related tasks and the impact of the event on the current simulation situation. For example, during a simulation, when an enemy target is successfully destroyed, the system will immediately push this information to users who have subscribed to the "target damage event", along with detailed tactical situation changes.

[0063] Example 5: Tracing and visualizing evaluation results

[0064] This Example 5 introduces the traceability and visualization display functions of the evaluation results.

[0065] Evaluation result tracing: After the simulation is completed, the system will generate an evaluation report, which includes evaluation results in multiple dimensions, such as mission completion, command decision-making quality, target damage effect, etc. Users can trace these evaluation results through the system. For example, users can choose to view the historical change trend of the "mission completion rate" indicator and trace back to the time points of each key event based on its change trajectory.

[0066] Visualization: The system uses a variety of graphical tools to visualize the simulation data and evaluation results. Users can view key events, changes in the command chain, and task execution progress at different stages through charts, timelines, situation maps, etc. For example, in the summary stage of the simulation, users can view the command relationship between the red and blue sides, changes in communication links, and the situation during the execution of each task through the situation map.
