[0002] In flight simulators, the interface system program serves as the bridge between the simulator's simulation platform and the hardware. However, due to the varying models and types of simulators, the acquisition equipment used varies, requiring customized development of the interface system. This customization not only increases software development and maintenance costs but also hinders the standardization of simulator production.

[0003] For example, the flight simulator interface system solution solves the problem of flight simulator interface systems being unable to adapt to multiple signal types and prone to signal confusion. However, its essence is still based on communication with a specific type of acquisition board.

[0072] The workflow of the present invention mainly includes the following steps:

[0073] (1) Device information management: First, the device management database system stores and manages the information of all devices. During the device initialization phase, the system reads the device information from the database and performs corresponding initialization operations based on the device information.

[0074] (2) Data Reading and Organization: During the data call phase, the data reading and processing module constructs a unified data structure to efficiently read and organize device information in the database.

The system uses a clock drift compensation algorithm and a hardware-level timestamp calibration mechanism to control long-term operating errors within the microsecond level, meeting the real-time requirements of high-precision fields such as aerospace.

[0078] In order to more clearly explain the modular distributed interface and multi-bus fusion system of the simulator of the present invention, the following is combined with Figure 1 Each module in the embodiment of the present invention is described in detail as follows:

[0079] An equipment management database system configured to store equipment information, including an equipment basic information table, an equipment technical parameter table, and an equipment application association table;

[0080] In this embodiment, the device management database system adopts a relational database;

[0081] The device basic information table stores device ID, device name and device status;

[0082] The device technical parameter table stores device gain, offset rate and basic clock parameters;

[0083] The device application association table establishes a binding relationship between the device and the flight simulator model.

[0084] Specifically, the device management database system uses a relational database for storage and management. The database table structure includes a device basic information table, a device technical parameter table, and a device application association table. The device basic information table stores the core attributes of the device, such as device ID, device name, device type, and device status. The device technical parameter table stores device configuration attributes, such as device gain, device offset rate, device base clock, and device cache size. The device application association table establishes binding relationships between devices and simulators, such as associating acquisition devices with simulator models and simulator classes.

[0085] This invention introduces a device management database system to store and manage information about all devices. The database system uses a unified data structure, categorizing device information into basic information, technical parameters, and application-related components. These information is then entered into the database for management. This design makes the storage and management of device information more standardized and efficient, laying the foundation for the universalization of the interface system.

[0086] The data reading and processing module is configured as a multi-layer nested data structure defined by a dynamic memory allocation mechanism and pointer form, which reads device information in real time and converts it into structured data;

[0087] Dynamic memory allocation mechanism, which specifically includes:

[0088] During the data reading process, a quantity variable is introduced to record the amount of data currently being processed in real time;

[0089] The number of the data structures is dynamically determined based on the actual results of real-time queries from the device management database system, and corresponding memory space is allocated in the heap memory through a dynamic memory allocation function;

[0090] After the data is read, the memory release dynamic memory allocation function is called to reclaim the allocated memory space.

[0091] The dynamic memory allocation function in this embodiment is preferably: malloc function or calloc function.

[0092] Through the dynamic memory allocation mechanism and the multi-layer nested data structure defined in the form of pointers, device information is read in real time and converted into structured data. Specifically:

[0093] Read the required device information from the device management database system through SQL query statements;

[0094] Based on the amount of device information read, a corresponding number of multi-layer nested data structure instances are allocated in the heap memory through the dynamic memory allocation mechanism;

[0095] Filling the device information into the data structure instance to form structured data;

[0096] The structured data is transferred to the modular processing module to be distributed to the modular distributed interface module and the multi-bus fusion platform.

[0097] This invention utilizes a carefully designed data access mechanism. By constructing a unified data structure, it enables efficient access and organization of device information within the database. This data structure, with its complex, multi-layered nested structure, accurately maintains the complex data associations between various types of device information, ensuring data integrity and logic.

[0098] To further optimize data processing efficiency and enhance system flexibility, data structures are defined using pointers. The use of pointers makes data transfer and manipulation within memory more efficient, significantly reducing the data copying overhead associated with traditional value transfer methods, thereby significantly improving the overall performance of the system during data reading and processing.

[0099] During the data reading process, the system introduces a quantity variable to accurately record the amount of data currently being processed. The number of data structures is not statically set in advance but is dynamically allocated based on the actual results of real-time database queries. This dynamic memory allocation mechanism cleverly avoids the problems of wasted or insufficient memory resources that can arise with traditional static allocation methods, enabling the interface system to flexibly and efficiently complete data reading and processing tasks based on the dynamic changes in actual data volume.

[0100] A modular processing module configured to obtain the structured data and task requirements and distribute them to the modular distributed interface modules and the multi-bus fusion platform for connection;

[0101] In this embodiment, the data transmission mechanism of the modular processing module is:

[0102] The modular processing module obtains the following data from the data reading and processing module:

[0103] Structured device information: including device ID, type, technical parameters (such as gain, offset rate) and application association, organized by the data reading and processing module through multi-layer nested data structures;

[0104] Memory-mapped preprocessed data: physical address binding information directly accessed through shared memory, used to dynamically associate device channels with simulation platform variables;

[0105] Real-time task instructions: including task priority, processing timeliness requirements and target module identification, are generated and delivered by the event-driven architecture.

[0106] Data transmission path and distribution logic of modular processing modules:

[0107] Assignment to modular distributed interface modules:

[0108] According to the device type label (such as sensor, actuator, controller), the data is routed to the corresponding functional unit:

[0109] Data acquisition unit: receives raw signal data (such as analog and digital quantities) and transmits it through shared memory or high-speed communication bus;

[0110] Data processing unit: receives data that requires complex calculations (such as filtering and calibration) and directly transmits it through memory mapping using zero-copy technology;

[0111] Data output unit: receives processing results and sends them to the flight simulation system platform through a standardized interface protocol.

[0112] In this embodiment, the distributed interface also includes interfaces of various I / O industrial computer devices.

[0113] Distribute to multiple bus convergence platforms:

[0114] Dynamically route data via the bus adaptation layer protocol based on the target device's bus type (e.g. ARINC429, CAN, Ethernet):

[0115] CAN bus module: distributes device control instructions or status query requests to the specified CAN bus module (1-436);

[0116] Data transmission technology optimization:

[0117] Shared memory interaction: Modular processing modules directly read and write data to the shared memory area preloaded by the reading and processing modules, avoiding data replication delays;

[0118] Zero-copy technology: When transferring data across modules, data buffers are directly manipulated through pointer references or memory mapping, eliminating intermediate copy overhead.

[0119] Event-driven transmission: Use message queues or event triggers to encapsulate data into event packets (including timestamps and priority tags) to ensure that real-time tasks are processed first.

[0120] Modular distributed interface module, including multiple independent functional modules with data processing functions;

[0121] The independent functional modules include a data acquisition module, a data processing module and a data output module that achieve seamless docking and collaboration through a standardized interface protocol.

[0122] For modular distributed interface modules, the present invention supports parallel development and testing, that is, each module can be developed and tested simultaneously without interfering with each other, which improves the development efficiency and maintainability of the system.

[0123] During the parallel development process, it is necessary to ensure the consistency of interface standards between modules to avoid integration problems caused by interface mismatch.

[0124] Modules communicate and exchange data through shared memory, communication buses, or network protocols. For example, the data acquisition module can pass the collected data to the data processing module through shared memory for processing.

[0125] In order to ensure the reliability and real-time nature of communication, technical means such as event-driven architecture or message queues can be adopted.

[0126] The multiple bus interfaces in this embodiment include at least an aviation bus and a CAN bus.

[0127] The system integrates multiple bus technologies, such as aviation bus, CAN bus, serial communication, network protocol, etc., to build a distributed data communication platform. These bus technologies each have their own characteristics and application scenarios. Through integration, comprehensive support for different devices and systems can be achieved.

[0128] Develop unified interface standards and communication protocols for each bus technology to ensure seamless connection and efficient collaboration between different bus technologies.

[0129] Distributed data processing:

[0130] By using distributed computing technology, data processing tasks are assigned to multiple nodes for parallel processing, which improves the processing power and scalability of the system.

[0131] In the distributed data processing process, it is necessary to ensure data consistency and synchronization between nodes. This can be achieved by using technologies such as distributed databases and distributed caches.

[0132] For the real-time assurance module, the present invention uses a high-precision timer to build a unified time synchronization mechanism, and controls the timestamp accuracy within the millisecond level by combining the hardware-level clock source with the software scheduling algorithm. At the same time, memory mapping technology is used to achieve dynamic binding of device channels and simulation system platform variable parameters, reducing the delay of intermediate data copying. Combining the event-driven architecture with zero-copy technology, a pipelined processing link of "acquisition-mapping-processing" is formed to achieve millisecond-level data throughput. In addition, the system also controls the long-term operation error within the microsecond level through the clock drift compensation algorithm and the hardware-level timestamp calibration mechanism, meeting the real-time requirements of high-precision fields such as aerospace.
