Display part 3, computer or palm PC.Utilize computer or palm PC to show the result who tests out.
Wherein translation interface module 2 workflows are made up of following steps:
(1) digital of digital video data conversion.From the digital implementation front-end collection to data use hardware conversion to be internal image.
A. at first, the picture size according to the output of PC setting UVC interface defines onesize internal virtual figure image width high parameter;
The scanning sequency of B.UVC image output is to begin from top-left coordinates, and first puts last point of right side according to the first row left side, then the second row repetition ... the order of delegation scans to the end.Construct two circulations according to this rule: first circulation is used for inner delegation mid point and from left to right circulates, and second loop nesting is used for vertical first row circulation of delegation to the end on first circulation.Capable refresh rate and row refresh rate that two round-robin cycle frequencys and UVC set are consistent.
C. judge above-mentioned two position attributions that recirculate a little, wherein interior loop is put corresponding X axial coordinate, the corresponding Y axial coordinate of outer circulation:
A. if grid position, the color of output grid;
B. if literal/scale position, the color of output character/scale;
If part of detecting 1 obtains the corresponding position of data, the color of output measurement point;
C. above-mentioned condition does not all meet, the output background color.
D. after outermost loop finished, the output of the video data of a two field picture finished, and two-layer circulation returns 0, and the frame rate of setting according to UVC begins circulation next time.
(2) SRAM frame data memory module.The image stream that (1) is generated is stored in the SRAM frame data memory module.In storage, information such as the measurement point that example dissolves from step (1) circulation, grid, literal can be by storage one by one.
(3) USBUVC device controller.Be used for data according to the standard format SRAM frame data memory module of UVC.The every two field picture of UVC standard-required is additional when transmission to comprise the image rise time, speed, the frame head of frame information.According to this requirement each parametric synthesis is become frame head, be added on the image starting position, send from USB port with image.On PC or PDA, the image that generates in the step (1) shows in the system software of computer or palm PC, supplies the user to watch.Utilize the corresponding systemic-function of UVC agreement, the user can store single image or continuous video recording on computers, further these data of analyzing and processing.
The UVC transmission is the virtual image that hardware produces at the internal simulation videoscanning among the present invention, and no longer is real video flowing, has broken through the application category of original UVC host-host protocol.
According to above-mentioned flow process, the non-visualized data that digital implementation is gathered becomes the video data that meets the UVC standard, and intuitively shows on computers according to the UVC agreement, has reached the object of the invention.
Concrete, be further described with regard to transmission, storage and the demonstration that how to realize test data in conjunction with Fig. 3 and Fig. 4.
Introduce the whole system operation flow process below.

Here with the digital oscilloscope example.Suppose from the digital implementation front-end collection to data be:
d(1)＝0.841，d(2)＝0.909，d(3)＝0.141，d(4)＝-0.756，d(5)＝-0.958，d(6)＝-0.279......
Subscript in the bracket is represented the order of sampled data.Numerical value is the data that A/D quantizes.Data volume and precision are by the setting decision of digital implementation.
In USB UVC modular converter, the parameter of in store UVC virtual image, and the current setting of digital oscilloscope, like X axle unit precision and indication range, Y axle unit precision and indication range etc.
According to the unit precision and the indication range of X axle, choose and extract the data block that needs from the test data memory module by precision by indication range.When display precision and storage precision are inconsistent, do suitable approaching or the feasible precision unanimity of finally sending the USBUVC modular converter to of sampling algorithm.Then with data according to the X axle, Y axle unit precision is converted into pixel coordinates.
In USB UVC module, construct line scanning and column scan that two circulations are respectively applied for virtual image.Wherein line scanning is nested in the column scan.Line scanning is that current line begins from left to right, and column scan is that first row of every frame begins delegation's end to the end.
The current point of scanning is carried out matching check to following message:
A. whether be the coordinate axis net point;
B. whether be words identification points such as numeral, letter;
C. whether exist the detection data to match.
For example above-mentioned d (1)=0.841 supposes that X axle precision is 1: 1, and starting point is 0, and Y axle precision is 1: 100, is (Y=84, X=1) point of coordinate points in the virtual image through transforming the back.(Y=84 in the time of X=1), detects this point for detecting the Data Matching point to point when rank scanning.
When running into above-mentioned each condition and setting up, the corresponding point example is turned to the color value of respective settings.Do not meet any condition, example turns to background colour.As shown in Figure 5 after using hardware conversion as internal image.
These pixels are converted into the pixel format that UVC supports according to the requirement of UVC standard, output in the UVC frame memory and store.Information such as the grid that example dissolves in the said process, literal constitute a complete image with the detection data and are stored.For example, image shown in Figure 5 is stored in the video buffer.
