Description
Technical field
The utility model relates to a kind of diesel engine main frame analogue system of skill upgrading.
Background technology
Diesel engine main frame analogue system is as crewman's training and the senior shipping management talent's cultivation as the important component part of marine engine room simulator, and half material object of the real ship operating effect from the sense organ visual effect to the rational faculty is at one of ring teaching and scientific research equipment.At present, such analogue system generally adopts PC and industrial computer as simulation computer, by data processing, IO interface and A/D, D/A data collecting card, go to control the operation of diesel engine main frame gas control screen, real ship control handwheel platform, Displaying Meter, warning device and diesel engine host driven propeller system and the simulation of the operation of real ship, fault setting and eliminating.Above-mentioned diesel engine main frame analogue system is when deduction diesel engine main frame actual condition, because PC and industrial computer are lower as the treatment effeciency of simulation computer, application program is subjected to the restriction of multitask non-real time operating system, so this system real time is relatively poor, and real ship effect of the manipulation verisimilitude is low.Just must simplify simulation mathematical model and will improve real-time, reduce the degree of accuracy of mathematical operation, thereby cause the decline of the control ability and the response speed of physical simulation equipment.Like this, the degree of accuracy and the real-time of diesel engine main frame analogue system can't be satisfactory to both parties, influenced the raising of the verisimilitude of emulation to a great extent.
Summary of the invention
The purpose of this utility model is to adopt the diesel engine main frame analogue system (based on the embedded emulation computing machine of ARM+DSP double-core integrated processor) of high speed more by skill upgrading, reach and improve emulation degree of accuracy and real-time, and the purpose of physical simulation device control ability, thereby more ideally set up the diesel engine main frame analogue system of one and half material objects at ring.
The utility model is achieved in that in order to improve the real-time and the degree of accuracy of diesel engine main frame analogue system, the simulation computer that must select for use simulation computer more at a high speed to replace PC and industrial computer to make up, adopt and directly control information and parameter are fed in the high-speed simulation computing machine by external input device (keyboard, switch etc.), and, deliver to LCD liquid crystal display and host computer by field bus control system (CAN bus) and carry out parameter, family curve and multimedia mode and show the result of high-speed simulation computer-solution.
Description of drawings
Fig. 1 is the diesel engine main frame embedded emulation system architecture composition frame chart based on ARM+DSP double-core integrated processor embedded emulation computing machine.
Embodiment
Describe in further detail below in conjunction with the structure composition of accompanying drawing the utility model diesel engine main frame embedded emulation system.
Referring to Fig. 1,1 is the mathematical model of pre-designed diesel engine main frame, it is implanted in the embedded emulation computing machine 2 that the ARM+DSP double-core integrated processor (model is TMS320VC5470) that is made of 32 single-chip microcomputers and digital signal processor forms, this simulation computer 2 as primary processor, is responsible for task management, input and output, the control of external unit and the operation of embedded OS by ARM nuclear (senior reduced instruction set computer microprocessor); DSP nuclear (digital signal microprocessor) is responsible for the fast data calculation process as from processor.Undertaken alternately by shared a part of storer and communication interface between two processors.Substitute the simulation computer that PC and industrial computer are formed thus.3 is external input device, as keyboard, switch etc., directly control information and parameter are fed to the ARM side of embedded emulation computing machine 2,4 is the LCD liquid crystal display, present the result that DSP resolves in the embedded emulation computing machine 2, as the family curve of diesel engine main frame and the setting of model parameter.5 are input and output (I/O) interface circuit, and embedded emulation computing machine 2 is through I/O interface circuit 5 control physical simulation equipment, as diesel engine main frame gas control screen 10 and real ship control handwheel platform, Displaying Meter and warning device 9.6 is synchronous serial interface, 7 are digital signal processor (model is TMS320LF2407), embedded emulation computing machine 2 is through synchronous serial interface 6 control figure signal microprocessors 7, again by thruster and the propeller system 11 of digital signal microprocessor 7 controls by the simulation of simulating electric machine.8 is field bus control system (CAN bus), digital signal microprocessor 7 is through field bus control system 8, be sent to host computer (industry control PC) 12 when DSP resolves fructufy in the embedded emulation computing machine 2, the artificial intelligence that obtains is carried out various multimedia modes and is shown, both realize the mathematical physics emulation of diesel engine host characteristics, built perfectly half simulated effect on the spot in person at ring in kind of a comparison again.
The release of the utility model diesel engine main frame embedded emulation system owing to adopted based on ARM+DSP embedded high-speed emulation platform, solved traditional PC and industrial computer as the degree of accuracy and the real-time of emulation platform can't be satisfactory to both parties deficiency.The control ability of the mathematical physics emulator of while elevator system, thus the perfectly half emulation atmosphere on the spot in person at ring in kind of a comparison built, be that the electromechanical properties of diesel engine main frame is studied, created the workbench of easy operating.
