Description

Technical Field

[0002] With the rapid evolution of modern naval warfare, the status of carrier-based aircraft in maritime operations has become increasingly prominent. The complexity and high technological content of the new generation of carrier-based aircraft have placed higher demands on the pilots' flying skills and the maintenance capabilities of the maintenance personnel. However, since actual equipment teaching is not only significantly constrained by natural conditions, but also has extremely high training risks and high training costs, existing training methods are difficult to meet the training personnel's needs for systematic learning of the entire process of carrier-based aircraft operation. To address this problem, this project has built a full-state training simulation system for a certain type of carrier-based aircraft. By constructing a highly simulated full-state training simulation environment, it replaces part of the actual equipment training, makes up for the lack of actual equipment teaching and training equipment, provides training personnel with an operating environment and training process close to real equipment, and provides strong technical support for improving the level of carrier-based aircraft training.

[0003] Virtual reality technology is constantly evolving, and simulation training is gradually being adopted by military training institutions worldwide. Simulation training systems have evolved, ranging from skills training to integrated tactical training, embedded training to distributed training, and are now making a mark in academic theory instruction, equipment operation instruction, on-the-job training, and equipment testing and evaluation. During simulation training, simulation systems require high-volume data communication. This, coupled with high throughput and low latency, places higher demands on the interconnectivity of simulators for simulation training.

[0004] The data subscription-based simulator interconnection system and method of the present invention can be used for interconnected communication between certain carrier-based aircraft simulators, supporting systematic learning of the full operational process of carrier-based aircraft by trainees, and providing an operating environment and maintenance process close to that of real equipment to enhance their operational capabilities. The interconnection method of the present invention is suitable for data exchange functions in similar simulators or heterogeneous systems, providing a reliable and convenient interconnection path for related distributed simulation systems.

[0132] It should be noted that the operation modes of the virtual control subsystem 105 include: simulation operation mode and operation observation mode:

[0133] It should be noted that the simulation operation mode is used to enable trainees to conduct corresponding subject training by operating the switch knobs of the simulated cockpit. Trainees can operate the switch knobs in the cockpit and complete the relevant operation training of the training subject through simulation logic solution: the switches and buttons in the virtual cockpit can interact during the simulation training process. Trainees achieve interaction by clicking the buttons / switches with the mouse. Clicking the object with the mouse in the engine will cause a collision, and the ray detection module will determine whether the object has been clicked. Trainees need to perform a certain sequence of operations according to the subject training needs. The interactive data processing records the steps of these operations and feeds back the data in real time to the target device system simulation unit at the back end for simulation calculation. The solution results are fed back to the simulated aircraft cockpit for instrument and visual display, helping to deepen their understanding of the usage characteristics of each system of a certain type of aircraft.

[0134] It should be noted that the operation observation mode is used to achieve a twin display of the corresponding operation in the cockpit simulator, making it convenient for instructors or trainers to intuitively view the operation status of the personnel in the simulator, and realize simulator operation monitoring or immersive observation and learning. In this mode, the simulator operation data is transmitted to the virtual operation subsystem through data acquisition. The virtual cockpit software plays the corresponding animation according to the transmitted action data to realize the virtual display of the simulator operation:

[0135] It should be noted that the number and ports of the virtual control subsystem 105 can be configured according to actual needs.

[0136] It can be seen that the simulator simulation interconnection system based on data subscription described in this embodiment adopts a highly simulated full-state training simulation environment and data subscription method for interconnection communication, supports the training personnel's systematic learning of the full process operation of the target equipment, improves the timeliness of data communication and the simulation degree of the training simulation environment, meets the needs of large-volume data communication, and solves the problem of insufficient actual teaching and training equipment during simulation training.

[0184] Optionally, based on the data subscription configuration information, the cockpit simulation subsystem receives and processes the simulation data to be processed through the network communication subsystem, and obtains and stores the cabin status information, including:

[0186] S32, determining whether the end type corresponding to the data source IP address is a publishing end, and obtaining a data segment type determination result;

[0187] It should be noted that if Figure 5 As shown, in this embodiment, the data transmitted in the network is defined as a topic, and the data generator and receiver are defined as a publisher and a subscriber, respectively, thereby forming a publish / subscribe data transmission model. Logically, there is no master-slave relationship between the nodes, and all points are in a peer-to-peer relationship. The communication mode can be point-to-point, point-to-many, many-to-many, etc. Connections are established under QoS control, and network parameters are automatically discovered and configured.

[0188] It should be noted that Publisher is an entity responsible for distributing data, and it can publish different types of data. Participants write data through the write operation of DataWriter. The write operation takes the appropriate type of object as a parameter. When the Topic associated with the DataWriter is defined, the type of the object is determined. When the data object has a new value, the write operation will notify the middleware. The actual message generation is controlled by Publisher and QoS. Publisher represents one or more DataWriter objects associated with it. When the data associated with the DataWriter object changes, it is responsible for deciding when to send the data and performing the actual sending operation. This action is driven by the relevant QoS. Associating a DataWriter with a Publisher defines a publication.

[0189] A Subscriber is responsible for receiving and distributing different types of data. Depending on its QoS, it can receive published data and make it available to the receiving application. Applications that wish to access data received by a Subscriber must use a typed DataReader associated with the Subscriber. The DDS middleware notifies participants of synchronization by calling appropriate methods on the Listener. Associating a DataReader with a Subscriber defines a subscription.

[0190] The connection between DataWriter and DataReader objects is established through Topic objects, which connect publishers and subscribers. Topics accomplish this by associating a name (unique within the system), a data type, and the QoS associated with the data itself. Thus, Topics enable publishers and subscribers that are loosely coupled or even unrelated in space and time to establish a connection:

Simultaneously, each simulator group's internal members use the system's built-in timer to implement a 10ms regular update. Testing has shown that using this synchronization method, the error per 10ms can be controlled within 11ms, meeting the real-time requirements of flight training.
