Example 1
Fig. 2 shows a dynamic scanning method for an LED nixie tube provided in thisembodiment 1, where the method includes:
s101: and identifying the brightness display gear of the LED nixie tube, and acquiring the standard segment display quantity and the standard scanning frequency of the brightness display gear.
In this embodiment, according to different brightness display requirements, the LED nixie tube may have a plurality of different brightness display positions, and according to the plurality of different brightness display positions, the scanning frequency of the LED nixie tube may be in a range, and the range may use fL～fHIs defined wherein fHThe scanning frequency, f, of the gear for maximum brightnessLThe scanning frequency of the gear is displayed for the darkest brightness.
The switching period of a COM port can be obtained corresponding to different scanning frequencies, that is, the opening time of the COM port corresponds to fHCOM port opening time t of a highest brightness display gear can be obtainedHCorresponds to fLThe COM port opening time t of the darkest brightness display gear can be obtainedLFurther, the opening time of a COM port between the highest brightness display gear and the darkest brightness display gear can be obtainedRange tH～tL。
For example, the scanning frequency of the LED nixie tube can be between 80Hz and 500Hz, wherein the scanning frequency f of the darkest brightness display gear positionLAt 80Hz, the scanning frequency f of the highest brightness display gearHIs 500 Hz. Therefore, the on-time (namely the switching period of each COM port) of each COM port ranges from 3.125ms to 0.5ms, wherein the on-time t of the COM port of the darkest brightness display gear positionLThe COM port opening time t is 3.125ms and the highest brightness display gearHIs 0.5 ms.
If the number of the brightness display gears of the LED nixie tube is X, and it is assumed that the scanning frequency interval between the two display brightness gears is uniformly set, the set scanning frequency of the ith display brightness is defined as the scanning frequency when 8 segments are all displayed under the ith gear, and then the set scanning frequency (Hz) of the ith display brightness is:
fi.set＝fL+(fH-fL)/(X-1)*(i-1)；

ti.set＝1/fi.set/4*1000。
for example, in the frequency range of 80Hz to 500Hz, if the brightness display position of the LED nixie tube is 5 positions and the scanning frequency intervals of the 5 positions are uniformly arranged, the set scanning frequencies of the 1-5 positions display brightness are 80Hz, 185Hz, 290Hz, 395Hz and 500Hz in sequence, and the COM port set opening times of the 1-5 positions display brightness are 3.125ms, 1.351ms, 0.862ms, 0.633ms and 0.5ms in sequence.
Setting the display quantity of the standard segments as Y, wherein Y can be any number from 1 to 8, and the standard scanning frequency (Hz) of the display brightness of the ith gear is as follows:
fi.sta＝fi.set*(8/Y)；

ti.sta＝1/fi.sta/4*1000。
for example, if the number of brightness display steps of the LED nixie tube includes 5 steps, the brightness display step of the LED nixie tube is set to 3 steps, and the standard segment display number is set to 8, the standard scanning frequency (Hz) of the LED nixie tube is:
fsta＝f3.set*(Y/X)＝290*(8/8)＝290Hz；
the standard COM port opening time (ms) of the LED nixie tube is as follows:

If the actual segment display quantity of the LED nixie tube is Z, the standard segment display quantity is Y, and the brightness display gear of the LED nixie tube is i gear, as mentioned above, the actual scanning frequency (Hz) of the LED nixie tube can be adjusted as follows:
f＝fi.sta*(Y/Z)＝fi.set*(8/Y)*(Y/Z)＝[fL+(fH-fL)/(X-1)*(i-1)]*(8/Y)*(Y/Z)；
the COM port opening time (ms) of the LED nixie tube can be adjusted as follows:
t＝1/f/4*1000。
for example, as shown in fig. 1c, if the LED nixie tube display is 1200, and the number of brightness display steps of the LED nixie tube includes 5 steps, the brightness display step of the LED nixie tube is set to 3 steps, and the standard segment display number is set to 8.
The font displayed by the first LED nixie tube is 1, the actual segment display number is 2, and the actual scanning frequency (Hz) of the first LED nixie tube is:
f1＝f3.sta*(Y/Z)＝[fL+(fH-fL)/(X-1)*(i-1)]*(8/Y)*(Y/Z)＝1160Hz；
the actual COM port on-time (ms) of the first LED nixie tube is:
t1＝1/f1/4*1000＝0.216ms。
the second LED nixie tube displays a font of 2, the actual segment display number is 5, and the actual scanning frequency (Hz) of the second LED nixie tube is:
f2＝f3.sta*(Y/Z)＝[fL+(fH-fL)/(X-1)*(i-1)]*(8/Y)*(Y/Z)＝464Hz；

t3＝1/f3/4*1000＝0.647ms。
the font displayed by the fourth LED nixie tube is 0, the actual segment display number is 6, and the actual scanning frequency (Hz) of the third LED nixie tube is:
f4＝f3.sta*(Y/Z)＝[fL+(fH-fL)/(X-1)*(i-1)]*(8/Y)*(Y/Z)＝386.67Hz；
the actual COM port on-time (ms) of the second LED nixie tube is:
t4＝1/f3/4*1000＝0.647ms。
s104: and scanning the LED nixie tube according to the adjusted actual scanning frequency.
As described in step S103, 4 adjusted actual scanning frequencies f are obtained for the LED nixie tubes with 4 COM ports respectively1、f2、f3、f4Then the step is executed with 4 actual scanning frequencies f1、f2、f3、f4The corresponding 4 COM ports are scanned.
