Description
Technical Field
The invention relates to a simulation test platform software design mainly used for supporting a simulation test platform, which is applied to a UI management subsystem of an avionic simulation test platform.
Background
The system simulation is a comprehensive and experimental subject which is established on the basis of control theory, similarity theory, information processing technology, computing technology and other theoretical basis, takes a computer and other special physical effect devices as tools, utilizes a system model to test a real or imaginary system, analyzes and researches test results by means of expert experience knowledge, statistical data and information data, and further makes decisions. Simulations were studied using either material objects or models thereof, until no computer was available. The physical model is visual in simulation image and high in fidelity, but is high in cost and long in period. The object-oriented simulation technology breaks through the concept of the traditional simulation method in theory based on object-oriented simulation, a simulation model is constructed according to objects forming a system and the interaction relation of the objects, the objects of the model usually represent corresponding entities in an actual system, so that the difference between the model and the actual system is made up, and the intuition and the comprehensibility of simulation research are enhanced because the natural thinking modes of an objective world are recognized in a consistent manner. The object-oriented simulation has the inherent expandability and repeatability, and provides a very convenient means for simulating a large-scale complex system. The object-oriented simulation is easy to realize the combination with computer graphics, artificial intelligence/expert system and management decision science, thereby forming a new generation of object-oriented simulation modeling environment and being more convenient for popularizing and popularizing the simulation decision technology in decision support and auxiliary management. In order to provide the peripheral environment required for the operation of the software under test, the simulated system provides the input equivalent to the actual peripheral environment to the software under test. The simulation method can be divided into physical simulation, semi-physical simulation, mathematical simulation, human-in-loop simulation and software-in-loop simulation according to different simulation system structures and implementation means. A physical model of the system is constructed according to physical properties of the actual system, and experimental studies are performed on the physical model. One part is described by a mathematical model, and one part is introduced into a simulation loop in a physical mode. Such simulations must be used for situations where there are subsystems that are difficult to model mathematically, such as in the aerospace field. Mathematical simulation is computer simulation. Firstly, a mathematical model of the system is established, the mathematical model is converted into a simulation calculation model, and the purpose of operating the system is achieved through the operation of the simulation model. Modern computer simulation consists of the software/hardware environment of the simulation system, animation and graphic display, input/output and other devices. From a similar basic level, the system simulation has two levels of structure similarity and behavior similarity. In the system design optimization development stage, the system simulation focuses on similarity of two aspects of structure and behavior: in software testing, the main focus is on behavioural similarity. This is mainly the difference caused by the difference between the study subjects. The former studies the performance of the system itself; the latter is to provide the peripheral environment required for the operation of the software under test. The research of the ICD-based avionic simulation test platform system comprises simulation environments such as vision, hearing, sensation of movement, force feedback and the like. A typical human-in-loop simulation is a visual simulation. The software is special software in a real object. Such simulations are also known as embedded simulations. According to the concept of the simulation classification, the system simulation belongs to mathematical simulation, namely, the software and hardware environments, animation and graphic display, input/output and other equipment of a computer simulation system. The electronic simulation test system is used for most functions of the management of the avionic simulation test platform when performing desktop electrical performance joint test and software test in the development process of the avionic simulation test platform, and comprises data collection, data distribution, instruction control, communication and the like, and interface environments of an electronic system and attitude and orbit control, energy, thermal control, measurement and control, effective load and other sub-system desktop electrical performance joint test. Therefore, the simulation of the electronic system is an indispensable important component in the process of developing the avionics system, and the establishment of an extensible and easily-configured electronic system simulation test platform according to requirements is the key of the formation of an integrated avionics simulation test platform. The perfect electronic simulation test platform with the uniform interface can enable the avionics comprehensive simulation system to achieve the purposes of effectively interconnecting, expanding and configuring, and improving the development efficiency and the development quality of the avionics system. The avionics simulation equipment can solve the problem of coordination among subsystems in scheme design, is favorable for development and debugging of airborne software in avionics design and reduces test time. Not only the development of the avionics system can not leave the simulation link, but also the development of other systems of the avionics equipment must firstly establish a simulation test platform to a certain extent, so in order to shorten the time of the link and improve the efficiency of simulation tests of other systems, a method for realizing the simulation test platform with good universality can be provided while establishing the avionics simulation test platform, so that the efficiency and the reliability of the simulation tests of other systems are improved, and a foundation is laid for achieving the effect of twice the result with half the effort of the whole development work. Traditionally, a software system of a simulation test platform mainly adopts a customized development mode, and a user interface (UI for short) for interface display needs to be drawn. The UI refers to the overall design of human-computer interaction, operation logic and attractive interface of software, and is a medium for interaction and information exchange between a system and a user. The purpose is to enable users to conveniently and efficiently operate hardware to achieve bidirectional interaction and complete the work which is expected to be completed by means of the hardware, the user interface definition is wide, the user interface comprises a human-computer interaction and a graphical user interface, and the user interface exists in the field of information communication between human beings and machines. The UI design refers to the integral design with beautiful interfaces such as human-computer interaction, operation logic, organization business logic, configuration bus driving and the like for software. The good UI design not only enables the software to become individual and tasteful, but also enables the operation of the software to become comfortable, simple and free, and fully embodies the positioning and characteristics of the software. Since UI design involves subject matters, the degree of expertise and scale of a design company are important conditions for determining the quality of a product as a subject of UI design. If a product does not have a UI or the UI is not well done, the product does not have friendly operability and cannot meet the requirements of users.
When the flight control system is checked, a test platform supplies power to all flight control system components, the platform checks self-checking information of all the flight control components, under the condition that the power-on self-checking works normally, an excitation unit simulates signals of systems such as avionics, control stability augmentation and flap control and the like to the flight control computer, a loading platform is controlled to load a steering engine and a balancing system, flight control working states are set on operating various flight control consoles and handles by combining simulation excitation signals and loading conditions, the flight control system enters a corresponding working mode to work normally, the test platform acquires working data of the flight control system, an interface control file ICD reflects a data flow structure of a comprehensive system, and for a complex system, ICD design usually needs verification, evaluation and correction for many times, and the process is reflected. The ICD is analyzed and then output to a software interface of a test platform, a tester can observe whether the flight control system works normally or not on an EFIS/EICAS simulation interface and a data monitoring interface, test software can judge test conclusions of various test items, and finally all test data are stored in a database. ICD data management design ICD refers to an avionic interface control file and defines input and output data formats between devices. Because avionics devices are numerous and data volumes are large, ICDs are often very numerous and cumbersome, which brings difficulties for querying and using. Therefore, the design uses the database to store ICD data and constructs ICD management software to manage all ICD data. ICD definitions for various types of onboard electronic devices are managed using a database. The ICD definition in the database should be mapped to the platform hardware. Namely, after the corresponding ICD is input, the test platform can call ICD related information by accessing the database to complete functions of data packaging, analysis and the like. The ICD file is an important content of the design of the avionics integrated system. In the manual drawing interface display, the types of connection interfaces are diversified due to the complexity and diversity of signals of tested equipment (UUT). The number of bus control files (ICDs) in one simulator is as many as hundreds, a single ICD (interface control file) comprises a plurality of data items, each data item corresponds to one control, thousands of controls need to be drawn, and the development time of the simulator is more than half; meanwhile, the drawing control belongs to repetitive work, the style of drawing interfaces of everyone is different, and due to the customized manual drawing, the difficulty is caused in the later maintenance and upgrading of the simulator, and a large amount of manpower and financial resources are consumed.
With the increase of the types of avionics and airborne avionic devices equipped by the avionics, the test requirements on the avionic system are higher and higher, and the avionic system has stronger universality and expandability and becomes a main performance index of the test system. However, most of the existing avionics system test equipment is dedicated to a special plane, that is, different test platforms are established for different models, so that each set of test platform is repeatedly designed and processed, the problems of low equipment utilization efficiency, large resource waste and the like are caused, and the requirement of new-period avionics test cannot be met. In order to improve the efficiency of testing avionics systems, increase the universality and save the scientific research expenditure, the existing interface automatic generation technology generally adopts the following three implementation modes:
based on the MFC framework, an rc file is generated according to the ICD file, the generated rc file is loaded in a resource view of the visual studio development platform, a software developer conducts fine adjustment on an interface control in the resource view in a visual mode, and then the rest of development work is completed manually.
Based on a WPF framework, using XAML language to describe the control type and control layout corresponding to ICD, generating XAML files, then loading the generated XAML files in a visual studio development platform, and a software developer finely adjusts the interface controls in a visual mode and then manually completes the rest development work.
Based on the self-defined interface configuration file, the control type, control data item information, control layout and the like corresponding to the ICD are described in an interface configuration file mode, and a specific interface control automatic generator is adopted to analyze the configuration file and automatically generate an interface.
In the three implementation modes, the rc file and the XAML file only provide description of the interface control, and cannot describe information (including data type, data length, encoding mode and the like) of the ICD internal data item, and developers still need to manually encode to establish the relationship between the ICD internal data item and the interface control, so that the subsequent workload is large; the interface configuration file contains ICD internal data item information, but the interface effect can only be seen after the interface configuration file is loaded, the preview effect cannot be achieved, and the ideal interface layout effect is difficult to realize. The three implementation modes only partially solve the problem of time consumption of interface control development on the surface, and do not really realize automatic generation of the interface control.
