Table 4 data interface description

In a specific data architecture, the data architecture of this embodiment establishes a data communication pipeline in a Socket manner, so as to ensure high-speed and reliable transmission of data between a user side and a server side or between user sides, as shown in fig. 4. The data architecture mainly comprises a server side and a user side. The user side completes management of the model end, the two-dimensional end and the three-dimensional end of each ship-shaped simulator on the computer by calling configuration service. When the local area network is used, the file service and the server can share one computer due to the fact that the bandwidth is enough.

The data architecture design should also comply with the following principles:

1) the method is characterized in that training files, state files, scene files, scoring standards and the like are used, programs of various turbine simulators need to be established for reasonable and scientific management, loading, storage and the like of various files can be efficiently and orderly achieved, and the method is visual, simple and understandable to use.

2) The related files and data of different simulators can be clearly divided, displayed, inquired and retrieved according to the data requirements.

3) The database should be selected as a free commercial database, and if additional charges are needed, the price and charging rules of the copyright are required to be defined. When local area network is deployed, XML files are adopted for data management.

4) The cross query requirements of all the information are complete, complete and accurate, the design and the planning are unified, the resource is recycled to the maximum extent, the customization can be realized as much as possible, and the design of batch processing and multiple selection functions is enhanced.

5) Each terminal is designed with a function of accumulating the total running time and the current running time and is stored in a configuration file regularly.

In a specific deployment architecture, as shown in fig. 5, a user accesses a server of the system through the Internet on a computer with a user side, and participates in multi-user collaborative training or online learning. The system is deployed behind a firewall to ensure the safety of the system; meanwhile, the server is deployed in a distributed deployment mode, so that the server and the server can operate independently without mutual influence, and stable service is guaranteed to be provided.

The deployment of the server can be flexibly arranged according to the field and the training requirement. When the user scale is large and the distribution area is wide, the system can be arranged in a wide area network and can also rent a cloud server. The scale and the performance of the server can be dynamically expanded according to actual conditions. When the user scale is small and is used for training and assessment in the local area network, the system can be deployed in the local area network, so that the influence of network bandwidth on assessment effect is reduced, and the maintenance of a server and data is convenient. The selection flexibility of the server is high, and the server can be a common PC, a professional server or a server cluster. The choice can be made according to the number of users to better save costs.

Based on the scheme, the system provides simulation training service, simulation evaluation service, ship turbine simulation operation data configuration service and data management service through a network, and can realize the following functions by combining a system data architecture, an application architecture, interface setting and the like.

1. User management function

1) The method has the function of user login. The user name login can be reserved in the device with the fixed position in a preset mode, and the user name login can also be actually carried out. Only one user can log in to one computer at the same time. The correspondence between the device and the internally reserved user name may be set.

2) Each user should be designed with browsing and operating rights and can set the rights. The view of the turbine simulation equipment is open, but the operational authority is limited to each virtual ship training member (non-visitors). The operable contents of the temporary administrator of the virtual ship are mainly as follows:

(1) and virtual ship grouping and operating environment setting.

(2) The interface displays a limit setting.

(3) Fault setting and variable setting.

(4) And controlling the operation of the virtual ship.

(5) And browsing the contents of the fault page.

3) After the coach joins the virtual ship, the student operation can be monitored on line. The coach is allowed to join a virtual boat one at a time. When another virtual ship is added, the current virtual ship needs to be exited. The coach has the functions of stopping and releasing each selected virtual ship or the virtual ship in which the coach is currently running for exercise under the condition that the coach does not obtain temporary management rights.

4) Multiple managers can be logged on the level of each hall, room, virtual ship. The authorities are in order from high to low a manager of the lobby, a manager of the room, an evaluator (manager) of the virtual ship, the earliest registrant in the virtual ship. The manager of the hall can monitor the rooms, the virtual ships and the personnel belonging to the whole hall in a grouping or independent mode, the manager of the rooms can monitor the virtual ships and the personnel belonging to the whole room in a grouping or independent mode, and the manager of the virtual ship can control the whole ship and the personnel in a grouping or independent mode. Each virtual ship can only be controlled by an administrator with effective supervision authority at any time. When multiple administrators at the same level attempt to exercise control over the virtual vessel at the same time, the person who initially gains control may be selected to maintain control. If the administrative privileges of a high level administrator fail, a low level administrator may take over. The grouping refers to the work of assigning or withdrawing persons within the jurisdiction to or from a virtual ship to play a role. The permission suggestion capable of grouping is very flexible, can fully meet the actual requirement and is convenient to use.

5) If the high-authority manager does not implement operation control, quit the original control or end the process of implementing control on a certain virtual ship, the next high-authority manager or the earliest joined role user in the ship automatically obtains the management authority, and the management authority is kept until the virtual ship voluntarily quits, naturally stops or the high-level manager forcibly seizes (the high-level manager can forcibly obtain the control authority of the low-level manager). If the user with the management right exits, the management right is transferred according to the same principle.

6) When an operation group arbitrates the management right, the members in the operation group can compete for the management right according to the order of the joining time, whether the management right is required to be different from the role.

7) When multiple ships cooperate in groups, the transmission of state files and the like does not affect the real-time performance of cooperation, or when the actual transmission speed of a network is insufficient in the cooperation of multiple ships, a corresponding mechanism is provided for solving the problems of continuation of a cooperation process, exit of individual members and the like, and meanwhile, enough state prompt is required. Downloading of large files suggests arranging another file server to take on account when network bandwidth is insufficient.

8) In the local area network, in the same virtual ship, each data is based on the model end of a temporary administrator, if the administrator where the model end is located does not need the management authority, the model end can keep running continuously, but the management authority is handed over to other users. If the user of the computer where the model end is located normally exits, the model end of some other user (needing to be added with a competition mechanism for selection) needs to be activated, each state file at the breakpoint is transmitted to the user, and the data stream of other members points to the new model end. If the model end breaks the network, at this time, because each state file at the break point can not be transmitted, the delay (for example, 30 seconds, the time can be set) can be set for waiting, and if the waiting time is exceeded, the group is released.

9) Roles or visitors added in the cooperative training process need to be allowed by the virtual ship manager first, and all online users of the ship are informed of the information that new users are added.

10) The virtual ship and each user thereof have a brief real-time dynamic information display function, and a specific mode is set to display more detailed related information, including operation, error and alarm information.

2. Network communication function

The user side establishes connection with the model side through TCP/IP, and controls the model side to multicast the IP address of the state information to each two-dimensional side and three-dimensional side in the operation group through the connection. The user end establishes connection with each two-dimensional end and three-dimensional end in the virtual ship through TCP/IP, informs each two-dimensional end of IP address and port number of the model end for receiving the state synchronization information, and sends operation command information to the model end point-to-point UDP when each computer of the whole virtual ship is positioned in one multicast group, and sends operation command information to the service end point-to-point TCP/IP through the user end of the computer in each multicast group when the computer is positioned in more than one multicast group.

The user side needs to send the information of the user name and the role information of the three-dimensional end to the two-dimensional end for display, permission judgment and the like through the existing TCP/IP connection. The user side provides information such as IP addresses, user names and roles of all the collaboration ends to the model end through the existing TCP/IP connection, so that operation equipment information, user name information and role information are marked on each operation during historical record manipulation.

And the mutual searching and positioning commands of the local two-dimensional end and the three-dimensional end are also transferred through the user end. The two-dimensional end can switch the interface limitation, the current display interface is specified, the specification of the current position of the three-dimensional end is sent to the server end by the user end with temporary management right in the virtual ship through the established existing TCP/IP connection, then the server end is sent to the user end of the specified equipment through the established existing TCP/IP connection, and then the user end is sent to the controlled two-dimensional end or the controlled three-dimensional end through the established existing TCP/IP connection. And limiting a switching interface, wherein the designation of the current display interface and the jump of the three-dimensional display position belong to configuration content and an operation category, and the IP address and the user name of the computer sending the jump instruction are locally displayed and are collected into an operation record.

The two-dimensional end and the three-dimensional end are connected with the user end through TCP/IP, data interaction is carried out through a defined protocol, and the starting, the suspension and the ending of a task are controlled through commands sent by the user end. And the user side sends multicast addresses to the two-dimensional side, the three-dimensional side and the model side. Each virtual ship is preset to be allocated with a fixed multicast address which is unique to each ship.

The port numbers of the current model end, the two-dimensional end and the three-dimensional end are fixed. When sending in point-to-point UDP, its port number may collide with other programs such as QQ, etc. In order to avoid the used ports and prevent conflicts, automatic detection is required to be realized, and port numbers are dynamically allocated.

1) A detailed communication protocol for information interaction among all modules is formulated, and the detailed communication protocol comprises communication among a server side, a user side, a model side, a two-dimensional side and a three-dimensional side in a network environment, can realize reliable communication, and simultaneously can support wireless and wired network communication.

2) And when the analog computer equipment in the virtual ship is positioned in the same multicast group, the service data of the two-dimensional end, the three-dimensional end and the model end are communicated in a UDP mode. All data of the user side are communicated in a TCP mode.

3) When the UDP point-to-point communication is adopted, a response packet mechanism is added as much as possible under the condition of ensuring the system performance and normal work so as to check whether the communication is successful or not. If the response packet is not received, the number of times of retransmitting the information may be set, and if the number of times of retransmitting the information is set to 0, retransmission is not performed. And (4) on the occasion that whether the data transmission is successful is verified by the response packet, if the response packet cannot be received, carrying out communication fault information alarm and audible and visual prompt, and arranging the communication fault information alarm and audible and visual prompt into an alarm history record. The specific communication request needing to be added with the response packet is approved and confirmed by the first party after the communication planning of each part is completed. The mechanism of whether to add a response packet may be set by an option.

4) According to specific communication conditions, network transmission of partial data can be realized through technologies such as data compression, communication optimization and the like, so that dependence on network broadband high speed is reduced. The data transmission between the computers at the server side and the client side is reliable, stable, light and fault-tolerant.

5) When the cooperative operation is carried out, if the members in one virtual cabin join, drop or exit, humanized prompts are required to be carried out on other users in the same virtual ship, for example, people's portraits flicker appears, turn yellow flicker, disappear after turning gray flicker, and the like, and text messages and voice prompts are given. An automatic exit mechanism is set for users that are timeout and do not operate.

6) During network training and examination, the communication state, operation and synchronous command receiving and sending of the online PC computer and the accuracy of execution data can be statistically displayed. User information, role information, used equipment information and the like of the current virtual ship can be displayed.

7) The design of a simulation communication test function is required, and the communication test can be carried out on various network communications of the whole system by manually inputting data.

8) Each room may be set to a maximum number for the team training virtual ship based on network bandwidth and other resources, and the multicast IP for each operational group may be automatically assigned or may be manually set. The multicast IP address and the corresponding distribution table of the virtual ship and the multicast group are stored through an XML file. Special windows are available for modification, storage and application.

3. Communication monitoring function

And each program of the server, the user, the model, the two-dimensional end and the three-dimensional end is provided with a data sending and receiving indicator light for each path of network communication.
