The embodiment of the present invention is because adopt the initial point value of display of acquisition frequency hopping pattern and often shield displayable N frequency points; With the initial point value of described display for starting point, obtain N number of value of frequency point altogether successively, and obtain serial number corresponding to described N number of value of frequency point; Show the technological means of frequency hopping pattern corresponding to described N number of frequency according to described serial number, so reach at display resolution limited, still can show larger frequency hopping pattern, and enable naked eyes accurately identify the technique effect of frequency hopping pattern.
Application example is a DDS (Direct Digital Synthesizer with frequency hopping function below, Direct Digital Synthesizer) signal generator, the front panel of this instrument is 480 × 272 resolution for the LCD screen shown, if show frequency hopping pattern by traditional chessboard mode, when inevitably there is the larger frequency hopping pattern of above-mentioned display screen display, occur that naked eyes accurately cannot identify the problem of frequency hopping pattern.In order to show frequency hopping pattern as much as possible and tone hopping information on limited screen, and do not affect display effect with the increase of frequency, the display mode of application example of the present invention to frequency hopping pattern has made some improvements, and details are as follows:
As shown in Figure 4, for showing the interface layout schematic diagram of frequency hopping pattern in application example of the present invention.The argument section on the left side shows the optimum configurations relevant with frequency hopping, and the first row parameter is the frequency hopping pattern of current use; Second line parameter is the on off state of current frequency hopping; The third line parameter is the display type that current frequency hopping pattern uses; Fourth line parameter is the starting point numbering of current display; Fifth line is the stepped-frequency interval of current use; The frequency hopping pattern of the current use of the 6th behavior is counted.The frequency hopping pattern region on the right is for showing the frequency hopping pattern of current use, and can have two kinds of display formats, one is traditional checkerboard pattern, but has done simple change, to support that multifrequency point shows, and expresses more frequency hopping pattern information; Two is adopt the mode of form to show actual frequency values; Introduce respectively below and how to realize this two kinds of display modes.
1, frequency hopping pattern chessboard shows
When frequency hopping pattern chessboard shows, remain horizontal axis plots time, the longitudinal axis represents frequency, and gridiron pattern represents the frequency that frequency hopping pattern uses.
As shown in Figure 5, be the frequency hopping pattern schematic diagram of application example checkerboard pattern display of the present invention, wherein MapN is sequence valve, and SN is sequential value, and the sequential value that SN here represents can be unordered or orderly.Frequency hopping pattern chessboard totally 8 row 8 arranges, and forms 64 checker-wise, represents the frequency of the frequency hopping pattern of current use with dash area.What represent the time here is not with real chronomere, but numbers in order in frequency hopping pattern with each frequency and realize.Owing to being frequency hopping at equal intervals, a sequence number is multiplied by stepped-frequency interval can obtain corresponding frequency hopping point in hop period when.Stepped-frequency interval longer for width is placed on parameter region display, avoids time scale long, the problem of on-screen display (osd) area anxiety.Meanwhile, show the frequency hop sequences value that each point is corresponding at the top of frequency hopping pattern, this value indicates current point in frequency hopping pattern and is in which position in frequency hopping table, and this just allows frequency hopping pattern show more frequency parameter information.Here represent that the frequency of the longitudinal axis also does scale without actual frequency values, when the frequency difference distribution that will show is larger simultaneously, cannot represent at all.So, use the mode display frequency value of relative size here: first the Frequency point that will show is sorted from small to large, and on gridiron pattern often row represent the frequency that varies in size.
As shown in Figure 6, be application example frequency hopping pattern frequency axis flow for displaying figure of the present invention, comprise the steps:
601, find out frequency values not identical in the frequency hopping pattern that will show, leave in as64FreqTemp, and record different Frequency point number;
602, the Frequency point in as64FreqTemp array is sorted from small to large;
603, take out frequency successively, and the frequency in as64FreqTemp compares, write down the position that frequency is equal;
604, use position obtained in the previous step successively, the base coordinate of frequency hopping pattern chessboard calculates the position of each point on chessboard, and shows.
Now still there is two problems: one, chessboard can only show 8 frequencies, how frequency hopping pattern more than 8 frequencies is shown? two, the width of checker-wise just enough shows 4 characters, namely a four figures, and the frequency hop sequences of current display may be all 4 figure places, then often the viewing area of row sequential value all can occupy fuller, looking also can very unsightly, as shown in Figure 7, for application example 4 figure place of the present invention shows schematic diagram successively.
For first problem---show the pattern more than 8 points, introduce " display starting point " parameter and solve, the starting point of the frequency hopping pattern that this optimum configurations will show, user can carry out segmentation display frequency hopping pattern by arranging this value.For Second Problem---when the sequential value of frequency hopping point that will show or the numbering in frequency hopping pattern are 4 figure place simultaneously, can seem that interface is very crowded, substantially string, as shown in Figure 7, adopt following rule: no matter be that a few figure place first point shows all the time, 2nd point is if 4 figure places, and the 1st point is also four figures, then the 2nd point does not show, otherwise display, the like, as shown in Figure 8, be display schematic diagram in application example 4 figure place interval of the present invention.
As shown in Figure 9, be application example frequency hop sequences value of the present invention and frequency hopping pattern numbering flow for displaying figure, comprise the steps:
901, start;
902, a bit whether show before judging: if then go to step 904; If not, then 903 are gone to step;
903, judge whether current point is 4 figure places: if then go to step 905; If not, then 904 are gone to step;
904, current point is shown;
905, judge that a little whether institute all shows: if then go to step 906; If not, then 902 are gone to step;
906, terminate.
2, frequency hopping pattern form shows
As previously mentioned, the frequency axis of frequency hopping pattern shows by relative rule, the relative size of each Frequency point then can only be found out from pattern, and do not know concrete size, for addressing this problem, the implementation case is that the display of frequency hopping pattern introduces another one display format---form, user switches between form and chessboard by switching " display type " parameter.Frequency hopping table has 3 row, the numbering of the 1st row display frequency hopping point in frequency hopping pattern; The frequency hopping point value that 2nd row display is actual, unit is accurate to uHz, and length is maximum can reach 23 characters in display; 3rd row display frequency hop sequences value, the current point namely showing in frequency hopping pattern is which point in frequency hopping table.As shown in Figure 10, be the form display format schematic diagram of application example frequency hopping pattern of the present invention.Often shield and only show 6 frequencies, if more multifrequency point will be checked, regulate by display starting point.
The beneficial effect of the technical scheme of application example of the present invention: 1, shows the mode of the frequency display relative size on frequency hopping pattern chessboard, can solve frequency values spacing uneven and spacing is larger time frequency hopping pattern display problem; 2, frequency hopping pattern shows frequency hop sequences value simultaneously, can know frequency hopping point comes from which point in frequency hopping table easily, if when wanting to change certain point on frequency hopping pattern like this, directly can enter table editing interface frequently and carry out an editor, input puts sequence number, Modification Frequency accordingly; 3, by the mode of segmentation display frequency hopping pattern, can screen size be solved too small, cannot the problem of the whole frequency hopping pattern of complete display; 4, show frequency hopping pattern with forms mode, enable user clearly know the actual size of each Frequency point.
