Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.

It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0014] In this embodiment of the invention, a method for constructing an electromechanical simulation environment is provided, such as... Figure 1 As shown, the method includes: Step S101: Generate a configuration description file using a configuration-based embedded development tool, and burn the configuration description file to the embedded computer; Step S102: Using the electromechanical system control algorithm generation tool, obtain the core algorithm data corresponding to the embedded computer from the airborne software interface protocol, package the core algorithm data and transmit it to the embedded computer, obtain the standard algorithm data from the electromechanical system standard algorithm package, and burn the standard algorithm data to the embedded computer through the burning serial port of the embedded computer; Step S103: Connect the excitation system to the airborne software interface protocol via Ethernet, and connect the embedded computer to the excitation system via Ethernet; Step S104: The status information of the temperature sensor, pressure sensor, and switches, indicator lights, and buttons on the cockpit control board assembly are transmitted to the embedded computer through the excitation system via the airborne software interface protocol. Step S105: Receive simulation instructions from the excitation system through the debug signal interface device of the embedded computer, and send the state simulation result data generated by the embedded computer to the excitation system through the debug signal interface device.

[0015] Specifically, when data is transmitted to the embedded computer via the excitation system through the airborne software interface protocol, the main transmitted data consists of hardwired data and bus data. Hardwired data includes status information from temperature sensors, pressure sensors, and switches, indicator lights, and buttons on the cockpit control panel assembly. Bus data includes control commands, maintenance information, feedback, software version, and time information.

[0016] In practice, the following steps are used to generate a configuration description file using a configuration-based embedded development tool: In the configurable embedded development tool, control scheduling sequence data, data output location, data output cycle, and configuration parameter information are set; input data is obtained from the airborne software interface protocol, and the source of the input data is determined, wherein the source of the input data includes the hydraulic system, landing gear system, fuel system, fire prevention system, de-icing system, power supply system, lighting system, environmental control system, and fire prevention and rescue system; the algorithm functions to be used are obtained from the electromechanical system standard algorithm package; based on the control scheduling sequence data, the data output location, the data output cycle, the configuration parameter information, the input data, the source of the input data, and the algorithm functions, a configuration description file is generated.

[0017] In specific implementation, the configuration parameter information is achieved through the following steps: The configuration table includes a length, a number of device status parameters, a context buffer, a number of input / output signal table entries, and a data packet description table. The length of the configuration table defines the total number of data bytes in the configuration table for different simulation tasks. The number of device status parameters defines the total number of device status parameters that the configuration table needs to monitor. The context buffer stores temporary data during software operation. The number of input / output signal table entries counts the specific number of entries for input / output signals. The data packet description table defines the structure, encoding format, and parsing rules of data packets during data transmission.

[0018] In specific implementation, the following steps are used to obtain the core algorithm data corresponding to the embedded computer from the airborne software interface protocol through the electromechanical system control algorithm generation tool: The electromechanical system control algorithm generation tool accesses and parses the airborne software interface protocol, and extracts the corresponding set of dedicated algorithm functions from the airborne software interface protocol according to the control logic to be implemented by the embedded computer. The extracted set of dedicated algorithm functions is integrated and adapted at the code level according to the predefined algorithm interface format, parameter passing standard and data interaction protocol to generate dedicated core algorithm source code. The dedicated core algorithm source code is compiled to generate the corresponding core algorithm data.

[0019] In practice, the following steps are used to obtain standard algorithm data from the electromechanical system standard algorithm package: The electromechanical system control algorithm generation tool accesses the electromechanical system standard algorithm package; retrieves and calls standardized algorithm functions from the electromechanical system standard algorithm package, the standardized algorithm functions including motor speed control algorithm functions and temperature closed-loop regulation algorithm functions; and compiles the called standardized algorithm functions to generate corresponding standard algorithm data.

[0020] In specific implementation, the standard algorithm data is programmed into the embedded computer via its programming serial port through the following steps: A physical connection is established between the electromechanical system control algorithm generation tool and the embedded computer via a programming serial port. The compiled standard algorithm target file is transmitted and programmed into the address range of the specified non-volatile memory in the embedded computer in the form of a data frame sequence through the programming serial port. After programming, the programmed data is subjected to integrity verification. During the operation of the embedded computer, the algorithm function in the corresponding standard algorithm target file is dynamically loaded from the non-volatile memory and executed by parsing the algorithm call logic defined in the configuration description file.

[0021] Specifically, during the operation of the embedded computer, the core algorithm target data is also dynamically loaded in the same way.

[0022] In practice, the following steps are used to input simulation parameters and output simulation results via a display device: Connect the digital simulation display device to the excitation system; input simulation parameters through the digital simulation display device, and send the simulation parameters to the embedded computer through the excitation system; display the state simulation result data through the digital simulation display device.

[0023] In one embodiment of the present invention, such as Figure 2 As shown, 1 is the airborne software interface protocol, 2 is the configuration-based embedded development tool, 3 is the standard algorithm package for electromechanical systems, 4 is the electromechanical system control algorithm generation tool, 5 is the embedded computer, 6 is the debugging signal interface device, 7 is the excitation system, and 8 is the digital simulation display device.

[0024] The .crt file (configuration description file) is the core configuration and logic description file in electromechanical system application software. Its core function is to clearly define the main behavioral logic and operation scheduling rules of the software, and it is a "behavioral guide" to ensure that the system works stably according to the preset process.

[0025] From the perspective of the specific information contained, the .crt file not only clarifies the software's control and scheduling order (such as the startup priority and execution interval of each functional module), the source of input (e.g., data from sensors, external devices, or internal system cache), the algorithm functions used (specifying the specific algorithm module name and parameter passing rules to be called by the current task), and the output location (the hardware interface, storage address, or associated module to which the data needs to be transmitted) and output cycle (e.g., control signals with high real-time requirements need to be output once every 10ms, and status feedback signals can be output once every 100ms), but also contains a series of key configuration parameter information, as follows: (1) Configuration table number: As a unique identifier for the .crt file, it is used by the system to distinguish and manage the configuration tables of different functional modules, and avoid confusion when calling multiple files.

[0026] (2) Configuration table length: Defines the total number of bytes of data in the configuration table, providing a data boundary reference for the system when reading the file, and ensuring that the data is read completely without omission.

[0027] (3) Number of equipment status parameters: Determine the total number of equipment status parameters that need to be monitored in the current configuration table (such as the number of parameters such as motor speed, temperature, and voltage) to support the system in comprehensive monitoring of equipment operating status.

[0028] (4) Context buffer: Used to store temporary data during software operation (such as intermediate calculation results of the algorithm and temporary variables of inter-module interaction) to ensure the continuity and integrity of data when it is transferred between different modules.

[0029] (5) Number of input / output signal entries: The number of specific entries for input and output signals is counted separately. Each entry corresponds to detailed information such as the source, type, data format and transmission protocol of a signal to ensure the accuracy of signal interaction.

[0030] (6) Data packet description table: Defines the structure of data packets during data transmission (such as packet header identifier, data length field, check bit position), encoding format (such as binary, ASCII code) and parsing rules, providing a basis for the correct reception and decoding of data.

[0031] At the core logic support level, the logic algorithms within the .crt file are not temporary constructs, but rather encapsulated from modular algorithms accumulated over a long period in electromechanical systems. These modular algorithms have been verified in numerous real-world scenarios and possess high stability and strong reusability. For example, motor speed control algorithms and temperature closed-loop regulation algorithms are all integrated into the logic description of the .crt file in the form of standardized modules, allowing for direct invocation without the need for repeated development.

[0032] From the perspective of system necessity, the accurate parsing of the information contained in the .crt file is crucial: if the system cannot correctly identify the configuration table number, it will lead to configuration table call errors; if the configuration table length cannot be read, incomplete data reading or overflow may occur; if the parsing of information such as the context buffer and input / output signal table entries is abnormal, it will directly lead to chaotic software operation logic, or even cause equipment control failure. Therefore, the parsing quality of the .crt file information directly determines whether the electromechanical system application software can run normally and whether the scheduling is accurate, and is a key link to ensure the implementation of system functions.

[0033] .O files (including core algorithm data and standard algorithm data) are key algorithm support files in the development process of airborne embedded software for electromechanical systems. Their generation and application are closely related to configuration-based software design rules.

[0034] From the perspective of the generation scenario, the .O file is not created independently, but is generated in a dedicated integrated development environment (such as an IDE tool customized for aviation electromechanical equipment) for airborne embedded system design: developers first modularize and encapsulate the specific algorithms required by the electromechanical system (such as signal filtering algorithms and control decision algorithms), and then adapt and adjust the algorithm modules according to the unified rules of configuration software design (including algorithm interface format, parameter passing standard, data interaction protocol, etc.), and finally compile and generate the .O file, making it a logical package that conforms to the system specifications.

[0035] From a functional perspective, the .O file is the core algorithm support environment for the .crt file. During actual operation, the .crt file calls the corresponding algorithm modules in the .O file according to its defined logical rules. For example, when the .crt file specifies that "motor speed closed-loop control" logic needs to be executed, it will automatically associate with and call the .O file containing that control algorithm. The .O file then performs the specific algorithm calculations (such as calculating the corresponding control quantity based on the difference between the current speed and the target speed), and feeds the calculation results back to the .crt file, which then outputs them to the actuator according to preset rules. In short, the .O file provides "algorithmic computing power support" for the logic execution of the .crt file. The two work together to ensure the functional implementation of the electromechanical system application software. Without the algorithm support of the .O file, the logical rules defined in the .crt file cannot be executed, and the system cannot complete the preset control and monitoring tasks.

[0036] The debug signal interface device in an embedded computer is a hardware debugging device used to excite and receive hardwired signal outputs. Through this device, hardwired signals can be quickly injected or acquired. For example, by toggling a switch on the debug signal interface device, the position signal of the target aircraft under test can be measured to verify the correctness of its hardware design and internal channel design. In addition, the debug signal interface also has indicator lights that can receive control commands or other hardware output signals from the target aircraft under test. For example, the indicator lights can be used to determine the output result of the aircraft's integrated wheel load determination. When the indicator light is on, it can be considered that the aircraft wheel load is grounded; when the indicator light is off, it can be considered that the aircraft wheel load is in the air.

[0037] The debugging signal interface device has soft bus emulation capabilities, which can convert received Ethernet signals into soft bus signals such as AFDX, 1394B, and 429 and send them to the target machine under test, thereby connecting to the display simulation and excitation simulation of the digital simulation platform. In this way, the target machine has all the capabilities of hard-wired output, hard-wired input, and bus input / output, which can effectively support the development and debugging work of electromechanical software designers.

[0038] like Figure 2 As shown, through the interconnection of airborne software interface protocols, configurable embedded development tools, electromechanical system standard algorithm packages, electromechanical system control algorithm generation tools, embedded computers (debugging signal interface devices), excitation systems, and digital simulation display devices, the system is used to verify the matching and consistency of interface circuits for various types of sensor devices and terminal devices in the electromechanical system. It enables linkage functions with intelligent sensors and provides the ability to detect electrical parameters such as sensor voltage and current. It completes the rapid debugging and verification of the bus and interface of the airborne test piece, providing all the bus debugging resources and hard-wired excitation resources required by the electromechanical system, and realizing the simulation testing function for the control and management of the electromechanical subsystem.
