The invention patent is further described with reference to the accompanying drawing.
It is the composition block diagram of present system as shown in Figure 1:, it is characterized in that: ARM chip 1 is the control core of curve assessment
The heart, the chip are connected with liquid crystal touch screen 1 and FLASH chip 3, carry out curve using tool graphical user interface emWin and comment
The display design for estimating interface, handles the setting information that sends from liquid crystal touch screen 2, and by the assessment combined method set and
The parameter of each assessment content is sent to FLASH chip 3 and is stored.
As shown in Fig. 2, the present invention controls touch screen using TSC2046 chip, the chip and ARM chip are logical by SPI
Letter mode swaps data, is carried out with ARM chip PF6, PF7, PF8, PF9 pin multiplexing at SPI mode in the present invention
The control of TSC2046 chip；The principle that TSC2046 chip reads coordinate is as follows: when X-coordinate to be measured, first by writing control
To touch screen controller, so that applying a determining voltage on X+ and X-, and voltage is not added in word processed on Y+ and Y-, then X+ and
It just will form the parallel voltage field of uniformly continuous between X-.When touching touch screen surface with finger or felt pen, at contact
Voltage reflects position of the contact on X working face.The voltage is drawn out to touch screen controller by Y+ or Y- electrode,
It is converted using wherein A/D, the digital quantity of contact voltage, i.e. X-coordinate can be obtained.Y-coordinate is also measured with same principle.
Controller only needs the reading digital quantity by timer timing.The present invention uses emWin for interface instrument, first
After beginningization is completed liquid crystal and is touched, so that it may the application interface function in the library emwin be called to carry out interface.
As shown in figure 3, ARM core of the invention is attached by SPI port and external FLASH chip, of the invention is outer
Portion's FLASH chip uses W25Q64BVSSIG, and capacity is 8M byte, the SPI clock frequency of up to 80MHz, initialization completion
After it can be written and read.
It is as shown in Figure 4: to be liquid crystal touch screen curve assessment set interface schematic diagram of the invention.The set interface includes:
Four parts are arranged by the setting of window window, the setting of block window window, envelope window in the setting of thread window window.Wherein: if clicking thread
Window button, then the button is highlighted, and indicates to include thread window appraisal procedure in curve assessment content, and thread window is arranged in window 1
The longitudinal length of thread window window is arranged in lateral length, the window 2 of window, after being provided with, the frame of emWin is called to draw application
Interface function GUI_DrawRect (int x0, int y0, int x1, int y1), x0, y0 are thread window the preview window
Left apex coordinate, x1 are the lateral length that x0 adds thread frame, and y1 is the longitudinal length that y0 adds thread frame, the then thread being arranged
Window window carries out real-time display as unit of pixel in preview 1；If clicking through window button by the button is highlighted, table
Show in curve assessment content comprising by window appraisal procedure, the setting of window 3 passes through curve approaching side (upside, downside, the left side of window
And right side), the setting of window 4 is left side (upside, downside, left and right side) by the curve of window, and the window by window is arranged in window 5
The lateral length of mouth, the setting of window 6 after being provided with, also call the identical frame of emWin to draw by the longitudinal length of the window of window
Function processed fills out corresponding parameter, then what is be arranged carries out real-time display by window window as unit of pixel in preview 2；If point
Block window button is hit, then the button is highlighted, and indicates to include block window appraisal procedure in curve assessment content, and block window is arranged in window 7
The longitudinal length of block window window is arranged in lateral length, the window 8 of window, after being provided with, after being provided with, also calls emWin
Identical frame drafting function fills out corresponding parameter, then the block window window being arranged is carried out in preview 3 real-time as unit of pixel
Display；If clicking envelope button, which is highlighted, and indicates to include envelope appraisal procedure, window 9 in curve assessment content
The width for playing/stopping abscissa, the setting envelope of window 10 of envelope is set, after being provided with, on the basis of primary standard curve, with window
What mouth 9 was arranged plays/stops the lateral length section that abscissa is envelope, the data being arranged using window 10 as the width of envelope, passes through
Function depicts one group of polygon array, then application interface function GUI_DrawGraph () is called to draw out standard curve letter
Number recalls the filling that application interface function GUI_FillPolygon () carries out region setpoint color in corresponding position, draws
Envelope shade out.
As shown in figure 5, the curve assessment setting method main program flow chart of ARM controller in the present invention is given, at this
In main program, I/O port, initialization liquid crystal display, initialization touch setting, initialization timer, initialization are initialized respectively
EmWin, emWin interface function design interface is called, Open Timer device interrupts.
As shown in fig. 6, giving timer interrupt service program flow diagram of the invention.In timer interrupt service program
In, call the touch scan interface function GUI_TOUCH_Exec () inside emWin to be scanned touch screen, when there is outside
When touch information, immediately enters and handle corresponding touch information in the call back function of emWin.Due to each control of emWin
Different ID is all distributed, is pressed so different controls can be differentiated according to different ID in call back function, then does
Corresponding processing.
As shown in fig. 7, giving emWin call back function program flow diagram of the invention.Returning according to interface function first
Replying, it is determined whether to enable window settings for number, and successively judge whether it is thread window, by four kinds of window, block window and envelope assessment sides
