Description

Multifunctional table-type light-emitting nixie tube clock

The utility model relates to Time of Day indication articles for use, specifically multifunctional table-type light-emitting nixie tube clock.

The product that the clock of present employing singlechip technology combines with perpetual calendar occurs, and has multiple.But, take an overall view of these products at present, find that still there are the following problems: (many not enough) that function is more slightly, complex structure, the use element is many, cost an arm and a leg, style also difficulty do attractive in appearancely, be difficult to be accepted by vast family.And use the few less product of structure of element, and function is abundant inadequately again, and purposes is too single.

The purpose of this utility model is the problem at above-mentioned existence, provides a kind of structure small and exquisite, and circuit is simple, and cost is low, but the many multifunctional table-type light-emitting nixie tube clocks of function.

The purpose of this utility model is achieved in that and adopts the display of five light-emitting nixie tubes as the single-chip microcomputer of band internal memory, is the sound recording/displaying device with the integrated playback circuitry of voice.Under the concrete scheme:

Constitute the constituting of its circuit by the electrical equipment in support, clock shell and the shell: the P1 mouth of single-chip microprocessor MCU (P1～P17) be the field data mouth, output word segment encode, P1 mouth connect field driving circuit (2); The P3 mouth of single-chip microprocessor MCU is scanning mouthful, and output shows a position control signal, and connects with bit driver circuit (1), and (the common anode of LED1～LED5) links to each other for bit driver circuit and light-emitting nixie tube; The P23 of MCUP2 mouth links to each other with the continuous playback end PL1 of language integrated circuit HFC-L, the P24 of MCUP2 mouth links to each other with the base stage of the triode VT27 of the driving circuit of hummer, hummer one termination+6V, the other end is pressed the collector of the triode VT28 in the driving circuit, the grounded emitter of VT28, base stage connect the collector of VT27.

Five charactrons of the utility model employing are the time-division of read clock both, shows Gregorian calendar year, month, day, week and moon month, the day of perpetual calendar again.Clock adopts stable state to show for this reason, and perpetual calendar adopts transient state to show.Just time-division of read clock generally speaking, promptly so-called stable state shows; After pressing related key, the transient state that changes perpetual calendar at once over to shows, just shows a year several seconds earlier, when turning back to read clock again at last, branch and stable state show state.Adopt the method that is similar to " menu " between the various adjustment preparatory functions as for clock, perpetual calendar, playback, switch by class, reached and made things convenient for use, minimizing behaviour to use, and the purpose that can between numerous functions, switch fast, solved the contradiction between multi-functional and simple to operate.Single-chip microcomputer is also controlled integrated playback circuitry by burning program therein, realizes can presetting in one day automatic playbacks of automatic playback-automatic stop type for several times, two kinds of patterns (stopping automatically after the playback for several times) and non-automatic stop type (hand stops formula) playback automatically.

The utility model is luminous digital clock, luminous digital perpetual calendar, speech recording and reproducing three's combination, not only have three's function and purposes separately, because three's combination makes original some function of three and purposes have new technical characteristic again, and its structure is small and exquisite, circuit is simple, uses element few, with low cost, with the material consumption of much less, create I many use value.
