Description

Technical Field

[0001] This application relates to the field of modeling and simulation technologies, and particularly to a method, device, equipment, and storage medium for generating a crew alert simulation model. Background Art

[0002] An aircraft crew alert system (hereinafter referred to as the crew alert system) is a device used to attract the attention of the crew or notify the crew of an abnormal operation or aircraft system state. The crew alert system needs to receive the working state signals of the aircraft's on-board systems sent by the avionics system, and after certain logical processing, remind the pilot to handle immediately or attract the pilot's attention through sound, light, electricity, etc.

[0003] During the aircraft development process, conducting the design and analysis of the crew alert system through simulation means can reduce errors in the design phase, avoid a large number of modifications in the later stage of design, and effectively improve the development efficiency of the system. Therefore, it is necessary to model the crew alert system through various modeling languages (such as C / C++, Java, MATLAB / Simulink, SysML, Modelica, etc.), and integrate the model into a full-digital or semi-physical simulation environment to verify the working logic of the crew alert system.

[0004] The traditional modeling method is to manually analyze the logic of the crew alert system item by item, and then convert the alert logic into a simulation model in the modeling software. Since the crew alert system needs to synthesize the fault or status signals of more than 30 systems of the whole aircraft, with a large amount of signals and complex alert logic, there are problems such as large workload, easy errors, and difficult integration due to non-standard modeling during manual modeling.

[0035] In order to better understand the above technical solutions, the technical solutions of the embodiments of the present application will be described in detail below with reference to the drawings and specific embodiments. It should be understood that the specific features in the embodiments of the present application and the embodiments are detailed descriptions of the technical solutions of the embodiments of the present application, rather than limitations on the technical solutions of the present application. Without conflict, the technical features in the embodiments of the present application and the embodiments can be combined with each other.

[0036] Please refer to Figure 1 , which is a method for generating a simulation model of unit alarms provided by an embodiment of the present invention. The method specifically includes S101-S104:

[0037] S101, obtain a unit alarm definition file, where the unit alarm definition file includes: an alarm message number, an alarm message logical expression, and an alarm message text.

[0038] Among them, the alarm information label is used to uniquely identify the corresponding alarm information; the alarm message logical expression is used to determine whether there is an alarm; and the alarm information text is used to represent the relevant text information of the alarm.

[0039] S102, parse the unit alarm definition file to obtain the alarm message logical expression, and identify the variable name, alarm logical expression, and member function in the alarm message logical expression based on a regular expression.

[0040] In this embodiment, a file automatic analysis algorithm is used to analyze the unit alarm definition file. Information such as the alarm message number, alarm message logical expression, alarm message text, and input / output interface parameters corresponding to each alarm message is identified, and the Chinese and English states of the characters, the case of specific characters, etc. in each alarm message logical expression are checked for standardization. Among them, the member functions include: a signal validity judgment function, a signal invalidity judgment function, and a rising edge delay function.

[0041] Since the unit alarm definition file is manually compiled, there may be problems such as the mixed use of symbols in Chinese and English states and the use of arithmetic and logical operators not conforming to the MATLAB specification in the alarm message logical expression. It is necessary to check the standardization of the alarm message logical expression and automatically complete the replacement of non-standard symbols to make the alarm logical expression conform to the MATLAB syntax specification. To solve the above problems, in an optional embodiment provided in this application, after identifying the variable name, alarm logical expression, and member function in the alarm message logical expression based on a regular expression, the method further includes: checking the standardization of the alarm logical expression through the MATLAB syntax specification; if the standardization check of the alarm logical expression passes, adding the variable name, the alarm logical expression, and the member function to the corresponding state machine in the preset simulation model architecture; if the standardization check of the alarm logical expression fails, replacing the non-standard symbols in the alarm logical expression to obtain a standard alarm logical expression, and adding the variable name, the standard alarm logical expression, and the member function to the corresponding state machine in the preset simulation model architecture.

[0042] Specifically, analyze and identify the variable name and member function in the alarm message logical expression based on a regular expression (this member function is a custom function that realizes functions such as data validity judgment and signal delay). According to the MATLAB variable naming specification, design a variable name matching pattern (\<[a-zA-Z](+)?(_)?\w+), and automatically identify the variable name in the alarm message logical expression based on a regular expression. Based on the existing member function library, identify the member function in the alarm message expression through a regular expression (such as \<',TD,'(')).

[0043] During the process of logical expression analysis, the alarm message logical expression is automatically analyzed based on regular expressions, and the parameters and member functions in the alarm message logical expression can be automatically identified. Thus, the input / output types, variable types, initial values, etc. of the parameters can be automatically set by the program, and member functions can be automatically added, further reducing the workload of modeling.

[0044] S103, add the variable name, the alarm logic expression, and the member function to the corresponding state machine in the preset simulation model architecture.

[0045] In this embodiment, the corresponding variable is found from the ICD, and the variable name, the alarm logic expression, and the member function are added to the corresponding state machine in the preset simulation model architecture by calling the API function of MATLAB.

[0046] In an optional embodiment provided by the present application, after adding the variable name, the alarm logic expression, and the member function to the corresponding state machine in the preset simulation model architecture, the method further includes: automatically arranging each module according to the default size of each state machine in the preset simulation model architecture and the basic rule that the input module is on the left, the state machine is in the middle, and the output module is on the right, so as to prevent the models from overlapping after generation.

[0047] Based on the modeling method of Stateflow, a preset simulation model architecture applicable to all systems is designed. Each alarm message in the preset simulation model architecture is implemented by a state machine; the state machine includes two states, one is the normal state representing that the alarm message is not triggered, and the other is the alarm state representing that the alarm message is triggered. The state machine is added to the preset simulation model architecture by calling the add_block function, and two states are added to each state machine.

[0048] Specifically, in this embodiment, the Simulink model and the state machine model are automatically generated according to the preset simulation model architecture. The Simulink model is created by calling the API function new_system of MATLAB, and the open_system function is called to open the model in a load-only manner. The state machine (Chart module) is added by calling the add_block function, and two states are added to each Chart module. The MATLAB Function module is generated as needed according to whether the alarm message logical expression contains member functions. Among them, each alarm message corresponds to a Chart module, and each Chart module contains two states: Normal and Alert; the state machine defaults to the normal state. When the alarm logical expression is true, the alarm logic is triggered and the alarm state is entered; when the alarm logical expression is false, it returns to the normal state; the member functions used in the alarm logic are implemented through the MATLAB Function module. According to the identified member functions, the text content in MATLAB Function is automatically added, and finally the state transition conditions are automatically added.

[0049] In this embodiment, the alarm message may include types such as CAS, voice alarm, or information. Before the model generation, it is necessary to manually select which types of alarm messages need to be generated this time to assist the program in screening the message types required by the user. If the message number is empty during the model generation process, you can choose to ignore it or generate the model according to the default parameters. Configure parameters such as the simulation step size and start time of the model, and automatically configure them into the model by calling MATLAB functions during model generation. Preferably, in order to facilitate personnel operation, a human-machine interaction interface can be built. In the human-machine interaction interface, select the alarm message definition file of the system to be generated, configure the types of alarm messages to be generated, and support the simultaneous generation of one or more types of messages. The basic parameters of the model such as the simulation step size, start time, and end time can be configured in the interface. At the same time, in order to facilitate personnel to monitor the model generation process, the generation progress of the model should be displayed in the form of a progress bar, text, etc. When any abnormal situation occurs during the generation process, prompt information needs to be given to the operator, and subsequent operations should be completed according to the operator's instructions. There are two inputs to the system alarm logic model. One is the system fault information output by the system fault model and the alarm message status flag bits output by other system alarm logic models. The system alarm logic model comprehensively judges the alarm logic of this system based on the above two types of parameters.

[0050] S104, obtain the unit alarm simulation model by setting the parameter type, parameter initial value corresponding to the variable name in the state machine in the preset simulation model architecture, and the alarm result output by the state machine.

[0051] Set the model simulation parameters, save and close the model. Automatically set parameters such as the simulation step size and start time of the model, save and close the model. If only one model is generated at a time, the process can be terminated. If multiple models need to be generated in batch at a time.

[0052] In an optional embodiment provided by the present application, after obtaining the unit alarm simulation model by setting the parameter type, parameter initial value corresponding to the variable name in the state machine in the preset simulation model architecture, and the alarm result output by the state machine, the method further includes: when the unit alarm simulation model is generated, configure the simulation step size, start time, and end time into the simulation step size, start time, and end time by calling MATLAB functions.

[0053] The embodiment of the present invention provides a method for generating a unit alarm simulation model. First, obtain a unit alarm definition file, where the unit alarm definition file includes: an alarm message number, an alarm message logical expression, and an alarm message text; then parse the unit alarm definition file to obtain the alarm message logical expression, and identify the variable name, alarm logic expression, and member function in the alarm message logical expression based on a regular expression; add the variable name, the alarm logic expression, and the member function to the corresponding state machine in the preset simulation model architecture; finally, obtain the unit alarm simulation model by setting the parameter type, parameter initial value corresponding to the variable name in the state machine in the preset simulation model architecture, and the alarm result output by the state machine. Through the present application, the full-automatic batch modeling of the unit alarm simulation model is realized, greatly improving the modeling efficiency of the unit alarm simulation model, saving a large amount of human cost investment, and improving the quality of the unit alarm simulation model.
