Below in conjunction with embodiment and accompanying drawing the present invention is described in further detail.
Embodiment 1
As shown in Figure 1, the emulation built-in digital control system based on Windows operating system comprises:
The external unit that embedded type C NC software is connected is transplanted to Windows user's interface program that Windows operating system is generated;
The computing machine that contains Windows operating system;
The CNC analogue system that embedded type C NC software transplanting is generated to Windows operating system;
Driver in the embedded type C NC software is transplanted to the virtual Drive Layer that Windows operating system generates;
The virtual uC/OS-II operating system of using the uC/OS-II operating system in the virtual embedded type C NC of the Windows thread software to be generated.
One, virtual Drive Layer
Driver accordant interface function in virtual driving realization and the former CNC software for application layer software provides and the mutual essential interface of hardware, mainly comprises file system; Display driver; Keyboard drive, nonvolatile random access memory (NVRAM), input/output end port etc.
1.1, file system
Virtual driving uses the normative document IO interface of Windows to redefine the original file system interface, makes CNC software use the file system of Windows, and direct computed disk is as storer.
1.2, display driver
Display driver is that the drawing interface of CNC software provides a contiguous memory storage video data, and the size of data field is by display resolution and quality of colour decision.Windows user's interface program transfers bitmap to from display driver reading displayed data and shows, the liquid crystal display of simulation CNC.
1.3, keyboard drive
Keyboard drive provides the interface of keyboard scan status data visit for CNC software.Windows user's interface program is notified CNC software with the keyboard state of software simulation through keyboard drive.
1.4, nonvolatile random access memory (NVRAM)
In virtual driving, use a disk file storage NVRAM variate-value, when emulation CNC starts, read variate-value to ram space from file, supply CNC software to use; When emulation CNC closes, storage of variable values is arrived disk file.When making emulation CNC startup next time, the NVRAM variable remains the value of close moment last time.
1.5, input/output end port
Input/output end port drives and mainly comprises:
1.5.1 axis servomotor amount of movement output.When CNC running software generation axis servomotor moves, through virtual driving output amount of movement.In CNC software, the frequency of amount of movement output is very high, twice output be spaced apart Millisecond.Adopt the formation of going in ring to store the amount of movement of the each output of each axis servomotor in the virtual driving, offer Windows user's interface program and use, with the motion of emulation axis servomotor.
1.5.2 the input/output signal of embedded PLC.
1.5.3 carry out the aanalogvoltage output of speed of mainshaft control.
1.5.4 spindle encoder and the input of handwheel scrambler.
Two, virtual uC/OS-II operating system layer
Use a Windows thread to realize virtual uC/OS-II operating system, make CNC software directly run on Windows, reduce the work relevant in the migration process with operating system through virtual uC/OS-II operating system.This virtual level is that uC/OS-II is carried out the transplanting based on the Windows thread in fact, and its all tasks are all moved in the thread of Windows.
The transplanting of uC/OS-II mainly comprises three contents: the acquisition of clock TICK, and the generation that clock interrupts, task context switches.
2.1, the acquisition of clock TICK
Simulation softward itself is to operate under the Windows, does not need hard real-time, therefore adopts the software timer of Windows, produces simulated clock simulation clock TICK through the timeSetEvent () function that uses timing accuracy ms level.Its function prototype: MMRESULT timeSetEvent (UINT uDelay; UINT uResolution; LPTIMECALLBACK lpTimeProc, WORD dwUser, UINT fuEvent); The task definition that needs are periodically carried out in the lpTimeProc call back function, thereby accomplish the incident of required processing.Can increase a thread after calling this function, the time one is to then in this thread, calling call back function.
2.2, the generation interrupted of clock
TimeSetEvent () function call timing call back function and main thread do not play the effect of interruption simultaneously by the Windows operating system scheduling.So when calling regularly call back function lpTimeProc, must stop the operation of main thread; Withdraw from the operation that call back function then recovers main thread; These things all are placed on regularly call back function, just accomplish in the clock Interrupt Process function of uC/OS-II, and are as shown in Figure 2.
2.3 task context switches
The difference that task context here and uC/OS-II transplant on x86 is that segment register need not be preserved; Because the uC/OS-II task under Windows is just switched in same thread in fact; And under protected mode segment register, its value can not become in same thread.
Three, the CNC system software is transplanted
The CNC system software is externally regularly to carry out the interpolation processing in the interrupt response.The CNC system of simulation operates in on the virtual uC/OS-II system of Windows Thread, and all tasks of CNC all operate in the thread, and has only simulated clock TICK interruption.Simulation softward does not have the real-time requirement, carries out in the highest task of priority so can interpolation be handled, and periodically calls former break in service function, again the task process is carried out few modifications and gets final product.Like the flow process of Fig. 3 for the interpolation Processing tasks.
The foregoing description is a preferred implementation of the present invention; But embodiment of the present invention is not restricted to the described embodiments; Other any do not deviate from change, the modification done under spirit of the present invention and the principle, substitutes, combination, simplify; All should be the substitute mode of equivalence, be included within protection scope of the present invention.
