Detailed Description
The present invention will be described in further detail and in greater detail below with reference to the accompanying drawings for the purpose of facilitating understanding and practicing the present invention by those of ordinary skill in the art.
The invention discloses a rapid reconfigurable instrument design platform for an aircraft cabin, which has great advantages and potential in the fields of aircraft instrument design and flight simulation. As shown in fig. 1, the platform comprises a simulation test bench, a flight rocker, a throttle and pedal assembly, a reconfigurable instrument design module, a general flight simulation module, and a general instrument interface;
the simulation test board, as shown in fig. 2 and 3, specifically includes: a top control board, a front panel, a left console, a center console and a right console; together forming a typical aircraft cockpit layout; can provide a relatively realistic simulation test assessment environment for pilots.
The display pictures and instrument elements of each panel of the simulation test board can be reconstructed in real time under the control of the reconfigurable instrument design module, and the instruments can be driven to display under the control of the general flight simulation module without software redeployment.
The top control board comprises two 27 inch touch displays, and can simulate all switches and buttons of the top plate of the cockpit; the front panel comprises 4 27 inch touch displays and can be used for placing various display instruments of the front instrument panel of the airplane; the user can increase or decrease the size and the number of the display according to the own requirements;

As shown in FIG. 4, for the simulation test platform steel frame and the main structure, the platform adopts 5 steel frame main structures, and is connected with each other by bolts, so that the transportation and the assembly of the structure are convenient under the condition that the platform is firm and reliable. The left and right control console steel frame structures are attached with wooden table tops for placing the simulation control lever and the throttle table, and the floor is comfortable and attractive.
In order to meet the design and verification requirements of different aircraft instrument systems, the platform selects standard USB simulation flight rocking bars, throttle and pedal goods shelf products or customized standard USB simulation flight peripheral equipment as pilot operation input components.
The reconfigurable instrument design module comprises a database and a canvas; the database comprises a basic element library, a component library and a meter library. The designer uses elements in the database to perform instrument design and layout on the canvas and issues to the display specified by the simulation test stand.
The basic element library is internally provided with aircraft basic instrument elements, which are minimum display units with independent functions in instrument pictures, such as an airspeed zone, an altitude zone, a pitching ladder, an attitude meter, an engine N1 tachometer, an N2 tachometer, an exhaust thermometer and the like (the software can be understood to be internally provided with various typical instruments required for designing an aircraft), and each element can be provided with various fonts (all installed system fonts), colors (supporting RGB (red, green and blue) setting), sizes (supporting arbitrary setting), positions (supporting arbitrary layout in canvas) and patterns (internally provided with various main stream display patterns);
each basic element is associated with a generic meter interface for driving the change and display of the meter screen during testing. The universal instrument interface calculates all system parameters of the aircraft in real time through a universal flight simulation module.
Taking an engine N1 tachometer as an example: the data of the engine N1 represents the current low-voltage rotor rotating speed of the aircraft engine, and the engine N1 tachometer in the instrument picture can be displayed by a pointer instrument or a strip-shaped percentage instrument; when the basic elements are drawn, the rotating speed data is required to be converted into the pointer positions or the percentage scales required by instrument display, so that the display of the instrument pointer and the scales is driven.
The component library is an instrument picture which is composed of a plurality of basic elements and has relatively perfect functions, such as a main flight instrument and a navigation instrument;
the instrument library is a perfect plane instrument system picture formed by a plurality of components.
The component library is obtained by combining basic elements, the instrument library is obtained by combining component libraries, and the component libraries and the basic elements have the same setting function, so that the component libraries and the instrument libraries are convenient for designers to classify and divide.
Each element in the database provides corresponding style, color, font and other adjustment options, and supports arbitrary layout of positions and sizes in a design canvas, so that rapid design and modification of the instrument are realized.
The designer can directly drag basic elements, components or meters into the canvas from the database, and modify the attributes of fonts, colors, sizes, positions, styles and the like, so as to quickly generate a new meter picture.
The reconfigurable instrument design module also has an issuing function of instrument pictures, the issuing function automatically identifies the number of accessed displays and the resolution of each display, automatically calculates the relative coordinates between the displays and maps the relative coordinates with canvas coordinates, so that the currently designed instrument is issued to the appointed display of the simulation test board, each instrument is presented on the board body in a real relative relationship, and the evaluation test is conveniently carried out by a pilot.
The reconfigurable instrument design module is also provided with a rapid storage and import function part, the current canvas information is recorded and stored in an XML mode, the XML records the data indexes, user-defined style information, color information, size information, canvas coordinate information, design time, design version and the like of all basic elements, components and instruments in the current canvas, and the current design can be saved and version recorded in any design process; and the method supports loading the historical design data in any state, and automatically restores the instrument canvas corresponding to the historical version according to the XML information, so that the version management of the design is realized.
The general flight simulation module receives operation data of a flight rocker, an accelerator and a pedal assembly, calculates six-degree-of-freedom kinematics and a kinetic equation of an aircraft in real time, simulates aircraft system logic, supports a pilot to conduct typical flight maneuver simulation such as ground taxi, running, take-off, cruising, landing and the like, outputs corresponding flight state data and system parameters, and provides a simulation test environment for the pilot to evaluate instruments.
The universal instrument interface supports a tester to correlate data generated by the universal flight simulation module with instrument elements so as to drive corresponding instruments to display; the method mainly comprises a universal interface file and a corresponding interface mapping function.
As shown in fig. 6, the universal interface file stores most of data variables involved in the design process of the aircraft instrument and corresponds to the interface data of the universal flight simulation module one by one; each basic element in the database also stores the corresponding relation between the element and the universal interface file data, and when the instrument is released, each basic element added to the canvas sends a data request to the universal instrument interface component according to the corresponding relation, and a data interface corresponding to the basic element is found out from the global data interface. The general interface component traverses and judges whether the corresponding relation between each basic element and the global interface is consistent with the mapping relation between the general flight simulation interface and the global interface, if so, the basic elements and the global interface are mapped, thereby completing the automatic association between the instrument and the output data of the general flight simulation software and realizing the real-time driving of the corresponding instrument.
The working principle of the rapid reconfigurable aircraft cabin instrument design platform is as follows:
firstly, a designer designs each instrument of an aircraft system on a canvas through a reconfigurable instrument design module;
then, the designed instrument picture is released to a display corresponding to the simulation test board, so that a relatively real evaluation and verification environment is provided for a pilot;
the pilot operates the aircraft through the simulated flight rocker, the throttle and the pedal assembly, transmits corresponding control signals to the universal flight simulation module, performs six-degree-of-freedom motion and dynamics calculation of the aircraft, and simulates corresponding system logic to obtain system data of the aircraft;
the universal instrument interface component maps the data of each system of the aircraft to each display element of the instrument, thereby realizing the driving of instrument pictures; therefore, the pilot can evaluate the display effect of the instrument in the flight process.
When the pilot is dissatisfied with the display effect of a certain instrument element, for example, the font, the color or the size of the display of the instrument element is hoped to be adjusted, a designer can directly adjust the element through the reconfigurable instrument design module and issue the element in real time; the pilot can immediately see the new design effect and evaluate it. The whole process is very efficient without recompiling codes or changing deployment software.
