Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
The embodiment of the invention provides a nixie tube circuit which can be applied to but not limited to a countdown nixie tube in a traffic signal lamp. In the embodiment of the present invention, a seven-segment digital tube in a traffic signal lamp is taken as an example for explanation.
Fig. 1 is a schematic diagram of a digital tube provided in an embodiment of the present invention, and as shown in fig. 1, a seven-segment digital tube is composed of A, B, C, D, E, F, G seven segments, each segment being a light emitting diode (also called a digital tube segment). Each light emitting diode in the nixie tube has the same service life in the factory design process, but in the working process of the nixie tube, the effective working time of each light emitting diode is unbalanced, and the light emitting diode with the longest effective working time generally reaches the service life in advance, so that the whole nixie tube cannot work normally.
Fig. 2 is a schematic diagram of digital display of a nixie tube according to an embodiment of the present invention, as shown in fig. 2, when the nixie tube works, ten numbers of "0", "1", "2", "3", "4", "5", "6", "7", "8" and "9" are usually displayed; in the case of displaying different numbers, the lighted digital pipe segments are different, and the lighted digital pipe segments are represented as '1'; if the digital pipe section which is not lighted is represented as "0", the lighting condition of each digital pipe section when 0-9 figures are displayed is shown in table 1.
Table 1 shows the lighting condition of each digital pipe section in 0-9 figures
| Displaying content | A | B | C | D | E | F | G |
| 0 | 1 | 1 | 1 | 1 | 1 | 1 | 0 |
| 1 | 0 | 1 | 1 | 0 | 0 | 0 | 0 |
| 2 | 1 | 1 | 0 | 1 | 1 | 0 | 1 |
| 3 | 1 | 1 | 1 | 0 | 0 | 1 | 1 |
| 4 | 0 | 1 | 1 | 0 | 0 | 1 | 1 |
| 5 | 1 | 0 | 1 | 1 | 0 | 1 | 1 |
| 6 | 1 | 0 | 1 | 1 | 1 | 1 | 1 |
| 7 | 1 | 1 | 1 | 0 | 0 | 0 | 0 |
| 8 | 1 | 1 | 1 | 1 | 1 | 1 | 1 |
| 9 | 1 | 1 | 1 | 1 | 0 | 1 | 1 |
When the numbers 0-9 are displayed (i.e. one display period of the nixie tubes), the actual lighting times of each nixie tube section are shown in table 2.
TABLE 2 actual number of times each nixie tube segment in nixie tube is lit up in one display period
| A | B | C | D | E | F | G |
| 8 | 8 | 9 | 6 | 4 | 7 | 7 |
Through calculation, the average lighting times of each digital pipe section in the digital pipe in one display period is 7; as can be seen from table 2, the actual lighting times of some nixie tubes exceed the average lighting times, and the actual lighting times of some nixie tubes are lower than the average lighting times, as shown in table 2, the leds in the nixie tube C segment are used 9 times, while the leds in the nixie tube E segment are used only 4 times.
In the traffic signal lamp, the count-down nixie tube is used when the signal lamps with different colors are switched, and the number "0" is often the last number to be displayed and is accompanied with the switching of the signal lamps with different colors, so the count-down nixie tube in the traffic signal lamp usually does not display the number "0". When the numbers 1 to 9 are displayed (i.e., one display period of the nixie tube is counted down), the actual lighting times of each nixie tube section are shown in table 3.
TABLE 3 countdown of the actual number of times each of the digittube sections is lit during a display period
| A | B | C | D | E | F | G |
| 7 | 7 | 8 | 5 | 3 | 6 | 7 |
Through calculation, the average lighting times of each nixie tube section in the countdown nixie tube in the traffic signal lamp in one display period is 6.142857. The inventor finds that if the C section and the D section of the nixie tube are interchanged every preset time, and the A section, the B section, the E section and the G section of the nixie tube are rearranged, combined and interchanged, the lighting times of all the nixie tube sections can be optimized to be larger than the average lighting times.
For example, the following switching operation is performed for a seven-segment nixie tube for countdown in a traffic signal:
switching for the first time: the number tubes of the C section and the D section are interchanged, the use frequency of the C section is reduced, the use frequency of the D section is increased, and the average level is basically reached; the A and E section digital tubes are interchanged, the use frequency of A is greatly reduced, and the use frequency of E is greatly increased;
and (3) second switching: exchanging the digital tubes of the C section and the D section; exchanging the A and B sections of digital tubes;
and (3) switching for the third time: exchanging the digital tubes of the C section and the D section; exchanging the digital tubes of the B and G sections;
and after replacement, repeating the switching operation for three times from the first replacement.
Through the long-term continuous exchange of the driving parts of different nixie tube sections in the nixie tube, the actual use times of each nixie tube section in the nixie tube can reach the average use times, so that the utilization rate of each light-emitting diode in the nixie tube is improved, the whole service life of the nixie tube is prolonged, and the service life of various electronic equipment (such as a traffic signal lamp) adopting the nixie tube is reasonably prolonged.
Fig. 3 shows a process of switching between a segment C of the nixie tube and a segment D of the nixie tube, and fig. 4 is a schematic circuit diagram of the nixie tube before switching; FIG. 5 is a schematic diagram of a switched nixie tube circuit; as shown in fig. 4 and 5, the nixie tube circuit provided in the embodiment of the present invention may include: a nixie tube 10, a first switching circuit 20, a second switching circuit 30, a plurality of driving plates 40 and a plurality of signal terminals 50; the nixie tube 10 includes: a plurality of light emitting diodes 101;
