Description

Digital 60 minutes timing language informers

Affiliated technical field: the utility model relates to a kind of digital 60 minutes timers, relates in particular to a kind of digital 60 minutes timing language informers that preset timing time.

Technical background: at present, various timers are arranged on the market, be industrial used, the part even civil goods also comes with some shortcomings, timing time can not preset setting usually, and does not possess language and inform.Its function ratio is more single, needs the special occasions of timing to seem unable to do what one wishes to some, for example: gymnasium, massage parlor and chess and card room etc., as according to 60 minutes metered, must be by the clock manually-operated, extremely inconvenient.

Summary of the invention: in order to overcome above-mentioned deficiency and to impel the timer product up-gradation, the utility model provides a kind of setting timing time that presets, and timing finishes to be sent by the language circuit that " you are good, and welcome or thank you for coming! " novel timer, can satisfy the demand of many special occasions.

Way that the utility model solves and the technical scheme of being taked are: base divides the pulse signal when being produced by time-base signal generation circuit, send into the decade counter timing then, show between institute's timing by decoding scheme driving LED charactron simultaneously, and then produce a cut-off signals by the timing initialization circuit preceding circuit is locked, pass through Q simultaneously ₁And Q ₂The pronunciation of electron linkage switch triggering language circuit stops with the bulletin timing.

Electronic clock time-base generator, timing initialization circuit and three new technologies of " welcome or thank you for coming " language circuit have been adopted in the utility model such scheme, all adopt the newly developed or import integrated circuit in market, make product structure integrated, circuit is also simple, thereby reliability, accuracy improve greatly, have novelty, flexibly, advantage such as practicality.

Below in conjunction with drawings and Examples the utility model is further specified.

Description of drawings: Fig. 1 is the electrical schematic diagram of digital 60 minutes timing language informers of the utility model.

Comprise by IC referring to digital 60 minutes timing language informers of Fig. 1 the utility model ₁The time-base generator circuit, the IC that form ₂And IC ₃Decimal system counting/seven-segment decoder circuit and output terminal are by LED ₁And LED ₂The display circuit, the IC that form ₄With the time preset switch S ₂The timing initialization circuit of forming is at last by IC ₅And Q ₁And Q ₂The interlock electronic switch set becomes language to inform circuit.Below each part mentioned above is described one by one:

Embodiment: power supply V _Cc+ 5V and time-base generator IC ₁The 1st pin, decimal system counting, code translator IC ₂And IC ₃The 3rd, 14,16 pin, decimal system count splitter IC ₄The 16th pin, electronic switch Q ₁The 1st pin and diode D ₂Anode connects.Ground wire respectively with IC ₁The 4th pin, IC ₂And IC ₃The 8th pin, IC ₄The 8th pin, IC ₅The 6th pin connect.Reset switch S ₁One termination power V _CC, another termination pull down resistor R ₁, simultaneously respectively with IC ₁The 3rd pin, IC ₂And IC ₃The 15th pin, IC ₄The 14th pin connect R ₁Other end ground connection.IC ₂The 5th pin and IC ₃The 1st pin, IC ₄The 14th pin connects.IC ₂And IC ₃Decoding output terminal a, b, c, d, e, f, g respectively with LED ₁, LED ₂The corresponding seven sections pins of charactron connect.The time preset switch S ₂" position " respectively with IC ₄The 2nd, 4,7,10,1,5 pin connect S ₁" cutter " meet diode D ₁Anode.Diode D ₁Negative electrode and IC ₂And IC ₃The 2nd pin, and IC ₄The 13rd pin connect connecting resistance R simultaneously ₂One end, R ₃One end, R ₂Another termination capacitor C ₁Negative pole and electronic switch Q ₁The 3rd pin, R ₃Other end ground connection.Electronic switch Q ₁The 2nd pin and Q ₂The 6th pin be connected to each other Q ₂The 4th, 5 pin and language IC circuit ₅1st, 2 pin connect.The language IC circuit ₅The 3rd pin meet diode D ₂Negative electrode and capacitor C ₂An end, the 4th, 5 pin meet loudspeaker Y, C ₂Other end ground connection.

Described time-base generator circuit for example can adopt, and electronic clock chip 830A periphery converts the sub-signal circuit to by 60 frequency dividers.

Described decimal system counting, decoder circuit can adopt for example CD4026 decimal system counting, code translator.

Described decimal system timing initialization circuit can adopt for example CD4017 decimal system counting, divider.

Described language circuit could adopt for example TS087 music label, and built-in: " hello! Welcome ".

Described electronic switch Q ₁And Q ₂For example can adopt triode 9014 and 9015 etc.

Next the course of work of digital 60 minutes timing language informers of the utility model is described:

Energized, loudspeaker send promptly that " hello! Welcome " expression meets the guest.Click S then ₁Reset switch, timing formally begins, by IC ₁IC is sent in the sub-signal pulse of output ₂And IC ₃Timing, and by LED ₁And LED ₂Show between institute's timing.Meanwhile, timing initialization circuit IC ₄With S ₂Initialize switch connects, establish 10,20,30,40,50,60 minutes six grades, for example dial at the 1st grade, the expression time of day time is 10 minutes.Along with timing signal then, by IC ₄Output terminal on diode D ₁Export a high level " cut-off signals " with IC ₂, IC ₃, IC ₄All lockings are at LED ₁And LED ₂Upward shown is the actual timing time, and the language circuit is by interlock electronic switch Q simultaneously ₁And Q ₂Trigger, loudspeaker Y sends again that loud and clear " hello! Welcome " represent that relevant activity leaves it at that.

The above only is an example of digital 60 minutes timing language informers of the utility model, also can change over 120 minutes or 300 minutes etc. all belong to scope of the present utility model according to above design concept.
