Abstract
The invention relates to the technical field of simulation, in particular to a real-time semi-physical simulation system and a data acquisition method thereof. The invention adopts the technical scheme that the simulation system also comprises a DAQ device which acquires data of a hardware real object and is connected with the hardware real object; and after acquiring the data of the hardware real object, the DAQ device transmits the data to a host of a simulation platform. The data of the hardware real object are acquired by the DAQ device and then transmitted to the host of the simulation platform to carry out on-line adjustment. The method effectively solves the real-time problem of the complex simulation system, and can be widely applied to the semi-physical simulation system.
Description
Technical field
The present invention relates to simulation technical field, refer in particular to a kind of real-time semi-physical simulation system and collecting method thereof.
Background technology
A typical semi-matter simulating system is made up of main frame 1, goal systems 2 and hardware in kind 3; Structured flowchart is shown in accompanying drawing 1.Main frame 1 is created various prototypes, and generation and the code of downloading-running on goal systems.Goal systems 2 can be another PC, also can be an embedded system; Be used to move real time algorithm.Hardware in kind 3 is the objects in the real world, and by goal systems 2 controls, the target of emulation is exactly the correctness of verification algorithm on hardware in kind 3.
Said system, although can be through the IO mouth measurement data of goal systems, the data measured amount tends in the time of very big take a large amount of system resource, has influence on the real-time of analogue system.For the user, the quality of regulating effect often can only be reflected on the subjective observed result, the measurement data of deficiency in objective; Therefore be only applicable to not too complicated application or teaching demonstration occasion; The system of, complex algorithm big for data volumes such as real time signal processings is like application scenarios such as Aero-Space, radar emulation; Then can't realize real-time simulation.
Summary of the invention
One of technical matters that the present invention solves is to provide a kind of real-time semi-matter simulating system.
Two of the technical matters that the present invention solves is to provide a kind of collecting method of semi-matter simulating system.
The technical scheme that the present invention one of solves the problems of the technologies described above is: it is in kind to include main frame, goal systems and hardware; Main frame, goal systems and hardware material object link to each other in regular turn, also include the DAQ equipment that a pair of hardware material object carries out data acquisition and are connected with the hardware material object; Flow to main frame after the data of described DAQ equipment acquisition hardware material object as emulation platform; Described main frame includes the prototype that mainly is made up of Simulink software and creates module and mainly constitute online accent moduli piece by LabVIEW software; Described online accent moduli piece is to be used to read the ASAP2 file, to connect, read and write the functional module of goal systems specified memory address data with goal systems; Described DAQ equipment links to each other with online accent moduli piece.
The technical scheme that the present invention solves another technical matters is: hardware data in kind are gathered by DAQ equipment, are transported to mainly to carry out online accent ginseng by what LabVIEW software constituted as the main frame of emulation platform again.
The parameter regulation of analogue system of the present invention and data acquisition have formed complete loop; Under this system, algorithm accuracy can access fully effectively checking, and in conjunction with the user interface that LabVIEW sets up down, the user can be according to the measurement result real-time regulating system parameter of DAQ equipment.The effect of emulation can feed back to the user intuitively, helps the user to carry out proof of algorithm apace.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further specified:
Accompanying drawing 1 is existing analogue system block diagram;
Accompanying drawing 2 is analogue system block diagrams of the present invention.
Embodiment
See accompanying drawing 2; Imitative main frame 1, goal systems 2 hardware in kind 3 and the DAQ equipment 4 of including of real-time semi-physical simulation system of the present invention; Main frame 1, goal systems 2 and hardware in kind 3 links to each other in regular turn, and described main frame 1 includes the prototype that mainly is made up of Simulink software and creates module 11 and mainly constitute online accent moduli piece 12 by LabVIEW software; DAQ equipment 4 is one type of equipment that is used for data acquisition.Aforementioned DAQ equipment 4 links to each other with hardware in kind 3 with online accent moduli piece 12.The data of hardware in kind 3 are gathered by DAQ equipment 4, and the online accent moduli piece 11 that is transported to again as the main frame 1 of emulation platform carries out online accent ginseng.
The prototype of said main frame 1 is created module 11 can create various dummy models by the hardware controlled device of controlling in kind.Simulink also provides ASAP2 file Core Generator, and the ASAP2 description document comprises the full detail of relevant data object in the goal systems 2, like eigenwert (parameter, curve, MAP figure etc.), truly reaches the virtual measurement value, and the variable dependence etc.Under the Simulink environment, revise configuration, can be so that the user have set up system model in Simulink, and carry out generating an ASAP2 file simultaneously after automatic code generates.Online accent moduli piece 12 adopts LabVIEW (virtual instrument software of NI company exploitation) to set up graphical interfaces to carry out on-line proving.Utilize LabVIEW, the user is the user interface of design and simulation platform easily, realizes automatic measurement fast.LabVIEW also provides the kit of Long-distance Control, and the user can realize the Long-distance Control to VI through this kit.The tool storage room that utilizes LabVIEW to provide can connect with goal systems and measurement hardware easily.
Utilize the ASAP2 file can obtain the memory address of each parameter in the goal systems, data type, information such as span very easily.In order to realize read-write, under LabVIEW, developed and transferred the ginseng tool model to be used to read the ASAP2 file and communicate with goal systems to goal systems 2 specified memory address.This tool model has comprised and reads ASAP2, connects, reads and writes the functional modules such as data of goal systems specified memory address with goal systems.Utilize this tool model, can develop very easily and transfer the ginseng interface.Basic procedure is: create the ASAP2 file that module 11 establishments one comprise the full detail of relevant data object in the goal systems 2 by the prototype of main frame 1 earlier; Then, online accent moduli piece 12 is transferred the ASAP2 file, and reads the address information in the ASAP2 file; Again the data of goal systems specified memory address are read and write.
