[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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.

[0038] Combine the following Figure 1-Figure 3 The multi-node synchronization method based on simulated local area network of the present invention is described.

[0039] Please refer to Figure 1 The present invention provides a multi-node synchronization method based on a simulated local area network, comprising:

[0040] Step 100, splitting the assumption data of the teacher node into multiple data packets;

[0041] Specifically, in the hypothesis stage of training, the hypothesis data of the instructor side (i.e., the instructor node in this embodiment) is classified and split into several smaller data packets. For example, the hypothesis data of the instructor node is classified and split into several data packets according to the hypothesis type. The several data packets may include hypothesis data of hazardous sources, hypothesis data of injured persons, hypothesis data of decontamination personnel, hypothesis data of decontamination equipment, hypothesis data of decontamination vehicles, hypothesis data of weather factors, and hypothesis data of personnel allocation, etc. The split data packets are smaller in size and easier to develop and test.

[0042] Step 200, synchronizing the multiple data packets to the student node through a preset multi-thread and user datagram UDP protocol;

[0043] Specifically, a multi-person interconnection synchronization server is developed through the UDP (User Datagram Protocol) protocol. The several data packets obtained by the above classification and splitting can be synchronized to each student node through C# multi-threading and the multi-person interconnection synchronization server, such as Figure 2 As shown, synchronization within the same group and monitoring synchronization on the instructor side are achieved, reducing the performance consumption of data synchronization.

[0044] Step 300: synchronize the low-update frequency data between the student nodes based on the state synchronization mode, and synchronize the high-update frequency data between the student nodes based on the frame synchronization mode.

[0045] Specifically, the assumed data of the teacher node is split into multiple smaller data packets, and then different synchronization strategies (including state synchronization mode and frame synchronization mode) are used to synchronize the communication data between the student nodes in combination with the different data transmission types. For data with low update rate such as text communication and training evaluation (i.e., low update frequency data in this embodiment), the state synchronization mode is used for synchronization, such as Figure 2 As shown; for real-time updated data such as personnel data and vehicle data (ie, high update frequency data in this embodiment), frame synchronization mode is used for synchronization, such as Figure 2 shown.

[0046] This embodiment splits the assumed data of the instructor node into multiple smaller data packets, and then synchronizes the multiple data packets to the student node through preset multi-threading and UDP protocol. In combination with the different data sending types (high update frequency data and low update frequency data), different synchronization strategies (state synchronization mode and frame synchronization mode) are adopted accordingly. This can improve data interaction efficiency, avoid data flow congestion, increase the stability of synchronization operation, and improve the synchronization performance of LAN simulation.

[0047] In one embodiment, the multi-node synchronization method based on the simulated local area network provided in the embodiment of the present application may also include:

[0048] Step 101, splitting the assumption data of the teacher node according to the assumption type to obtain multiple data packets and the communication number corresponding to each of the data packets.

[0049] Specifically, the instructor computer (i.e., the instructor node in this embodiment) is operated by the instructor and is responsible for the training control, also known as the instructor terminal. The trainee computer is operated by the trainees in different roles, also known as the trainee terminal. The instructor terminal and the trainee terminal are connected through a local area network. The internal data synchronization is realized by relying on the UDP protocol. Without establishing a link, the instructor node can send encapsulated IP data packets to the trainee node.

[0050] Before the training begins, the instructor node edits the training scenario and classifies and splits the instructor node's scenario data into several items according to the scenario type, which may include scenario data of hazardous sources, scenario data of injured persons, scenario data of decontamination personnel, scenario data of decontamination equipment, scenario data of decontamination vehicles, scenario data of weather factors, and scenario data of personnel allocation, etc. A unique communication number (i.e., the communication number in this embodiment) is assigned to each piece of scenario data (package), so that the size of the data packet after the splitting is smaller, which is easier to develop and test.

[0051] This embodiment splits the assumed data of the teacher node into smaller data packets, so that the size of the split data packets is smaller and more convenient for development and testing.

[0052] In one embodiment, the multi-node synchronization method based on the simulated local area network provided in the embodiment of the present application may also include:

[0053] Step 400, monitoring the synchronization of each of the student nodes based on the preset multi-threading and the UDP protocol.

[0054] Specifically, Figure 2 As shown, the teacher node monitors the synchronization between the student nodes through C# multithreading and UDP protocol.

[0055] This embodiment reduces the performance consumption of data synchronization by monitoring synchronization through the teacher node.

[0056] Please refer to Figure 3 In one embodiment, the multi-node synchronization method based on the simulated local area network provided in the embodiment of the present application may also include:

[0057] Step 210, setting the synchronization frequency of the frame synchronization mode to be externally controllable, the frame synchronization mode being used to synchronize high update frequency data between the student nodes;

[0058] Step 220, based on the external controllability, testing the synchronization frequency to obtain an optimal frequency;

[0059] Step 230, determining a forwarding frequency of a synchronization server developed based on the UDP protocol, wherein the forwarding frequency is higher than the optimal frequency.

[0060] Specifically, for the frame synchronization mode of high-frequency data such as personnel data and vehicle data, the synchronization frequency of the frame synchronization mode is set to be externally controllable. By continuously testing the synchronization frequency of the frame synchronization mode, the optimal (synchronization) frequency is obtained to achieve a balance between effect and performance. Then, the forwarding frequency of the server (developed based on the UDP protocol for multi-person interconnection synchronization) is set higher than the data sending frequency (ie, the optimal synchronization frequency) to prevent the data flow of the multi-person interconnection synchronization server from being blocked.

[0061] This embodiment adjusts the synchronization frequency of the frame synchronization mode through testing to obtain the optimal synchronization frequency, thereby preventing the data flow of the multi-person interconnection synchronization server from being blocked.

[0062] In one embodiment, the multi-node synchronization method based on the simulated local area network provided in the embodiment of the present application may also include:

[0063] Step 310, determining a transmission type of synchronization data between each of the student nodes, wherein the transmission type includes a low update frequency;

[0064] Step 320: Synchronize the data with low update frequency between the student nodes based on the state synchronization mode, wherein the data with low update frequency includes text communication data.

[0065] Specifically, different synchronization strategies (including state synchronization modes) are used to synchronize the communication data between the student nodes in combination with different data transmission types. For data with low update rates such as text communication and training evaluation (i.e., low update frequency data in this embodiment), the state synchronization mode is used for synchronization, such as Figure 2 shown.

[0066] This embodiment adopts different synchronization strategies according to different data transmission types, thereby improving data interaction efficiency, avoiding data flow congestion, increasing the stability of synchronization operation, and improving the synchronization performance of local area network simulation.

[0067] In one embodiment, the multi-node synchronization method based on the simulated local area network provided in the embodiment of the present application may also include:

[0068] Step 330, opening the synchronization port corresponding to the frame synchronization mode;

[0069] Step 340: classify the data with high update frequency between the student nodes, and synchronize the classified data with high update frequency through the frame synchronization mode and the synchronization port.

[0070] Specifically, for real-time updated data such as personnel data and vehicle data, the frame synchronization mode is used for synchronization, such as Figure 2 An independent synchronization port (i.e., the synchronization port corresponding to the frame synchronization mode in this embodiment) is opened for the frame synchronization mode, and the synchronization data (i.e., the data with a high update frequency in this embodiment) is classified and processed to avoid mutual interference and increase the stability of operation.

[0071] This embodiment opens an independent synchronization port for the frame synchronization mode, classifies the synchronization data, avoids mutual interference, and increases the stability of operation.
