Effect.
It is described below in conjunction with working principle of Fig. 1-Fig. 3 to a kind of above-mentioned electronic watch and its driving chip:
For short pulse processing module 102, when push button signalling, which becomes high level from low level, to be inputted, and high electricity is inputted
When ordinary mail number is greater than key time delayed signal, the output end X31_Y of decoding chip U1 will become high level, X31_Y letter from low level
Number mainly from key-press input push button signalling be high level when and when detecting that NG_8 signal becomes high level from low level,
X31_Y signal will begin to change into high level output, and X31_Y is continuously high level, at the end of key-press input signal,
Push button signalling becomes low level from high level, and X31_Y will become low level from high level, and X31_Y signal is mainly defeated by key
Enter when push button signalling is low level and when detecting that NG_8 signal becomes high level from low level, X31_Y signal will start to become
For low level output.
When push button signalling, which becomes high level from low level, to be inputted, and input high level signal is greater than key time delayed signal
When, the output end X31_Y3 of decoding chip U1 will become high level from low level, and X31_Y3 signal is mainly pressed by key-press input
When key signals are high level and when detecting that X47_Y signal becomes high level from low level, X31_Y3 signal will be begun to change into
High level output, and X31_Y3 is continuously high level, and at the end of key-press input signal, push button signalling becomes from high level
Low level, X31_Y3 will become low level from high level, and X31_Y3 signal is mainly low level by key-press input push button signalling
When and when detecting that X47_Y signal becomes high level from low level, X31_Y3 signal will begin to change into low level output.
In key decoder module 101, N20_G is power-on reset signal, wherein in key decoder module 101 NG_8 and
X47_Y is time delayed signal, and low and high level duty ratio is 1/3 waveform, and NG_8 and X47_Y occur high level time it is different
Sample so causing X31_Y3 and X31_Y output signal different, and exports YYY signal after NAND gate combines, makes every time
Can all generate the YYY signal of fixed low level time when push button signalling end of input, YYY signal again with YYY2 signal nor gate group
It closes, wherein YYY2 signal is the long short pulse of key by the signal come out, and when push button signalling is long pulse, YYY2 is high level
Output, is otherwise low level output, and reaches the output of control YYY signal, and YYY just has letter when only key-press input is short pulse
Number output, and pass through two NOT gate final output OUT1 signals, reach the control effect of key short pulse, X31_Y2 is key
The output end of signal.
For long pulse processing module 103, when key decoder module 101 has signal to enter, and push button signalling is inputted
Greater than key delay time, X32_Y2 will have pulse output in key decoder module 101, and with long pulse processing module 103
It is connected, wherein N20_G is electrification reset circuit, and X99_Y is fractional frequency signal, and the period is 1 second.Wherein F is to reset in d type flip flop
Signal, and be connected with 101 output signal X32_Y2 of key decoder module, when inputting push button signalling has input, D triggering
The end F will be low level in device, and d type flip flop is enable to work normally, and when being greater than one second the key-press input time, X90_D signal will be by
Low level becomes high level, and output X91_Y signal is combined with X92_D signal NAND gate, and connects with the end G of d type flip flop
It connects, when being greater than X91_Y signal high level time 1 second, the end D and E of d type flip flop will have low pulse to export, d type flip flop output
End X92_E signal is connect with d type flip flop input terminal G, and finally exporting YYY2 is that X92_E signal is delayed by d type flip flop
A cycle time (X111_E signal is fractional frequency signal) of X111_E signal, final output YYY2 signal control long short pulse
The output of carry signal.
YYY signal is connect with the end A and B of d type flip flop behind the door by non-, and wherein X94_Y signal is when long pulse signal is defeated
D type flip flop carry reset will be given after entering, makes d type flip flop timing since new, and X92_E is that long pulse was produced greater than processing in 2 seconds
Raw high pulse signal, and with X94_Y signal by D trigger processing after generate X95_E reset signal, with signal
X92_E carries out logical combination, resets output final signal X94_Y to d type flip flop.
To sum up, a kind of electronic watch and its driving chip provided by the embodiment of the utility model, pass through key decoder module pair
Pulse signal is judged, when being less than the period of reference frequency signal in the period of pulse signal, by pulse signal transmission to short
The first carry signal, which is exported, after pulse processing module progress signal processing gives carry chip；It is greater than benchmark when the period of pulse signal
When the period of frequency signal, the second carry signal is exported after pulse signal transmission is carried out signal processing to long pulse processing module
Give carry chip.The D key of electronic watch is distinguished according to the length in key-press input burst length from there through key decoder module
With S key, realizing a key has the function of controlling two kinds of different key functions, is that a key carries out diversified control
System reduces production cost, solves existing electronic watch there is the control time is carried out using three keys, leads to driving chip
Area increase, increased costs, and cause using problem inconvenient for operation.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
