After receiving this accurate time-code, Jing data processor processes, you can from the walking time error of dynamic(al) correction quartz analog clock, make per only
The accurate time-code of unification of all receiving when walking of radio wave clock is controlled, it is achieved thereby that the high-precision Dose times of all radio wave clocks and display
The concordance of time.
The structure of existing DCF radio wave clocks generally comprises shell, the movement for being placed in inside the shell and other conventional fitments, its
The control circuit of movement generally comprises governor circuit and motor drive circuit, and governor circuit needs to be provided with several behaviour according to function
Make button.Motor drive circuit is connected to the outfan of governor circuit, is operated by governor circuit control motor drive circuit,
By motor drive circuit coordinate corresponding drive mechanism drive second hand, minute hand and when needle movement, and then function when realizing.
But the movement control circuit of existing DCF radio wave clocks, typically without illuminating lamp, will see that the time is very inconvenient at night.
Utility model content
The purpose of this utility model is to provide the movement control circuit for seeing time more conveniently DCF radio wave clocks a kind of night.
To achieve these goals, this utility model is adopted the following technical scheme that：
A kind of movement control circuit of DCF radio wave clocks, including battery, governor circuit, motor drive circuit and phonation circuit,
Working power is provided for whole movement control circuit by battery, the governor circuit includes main control chip and its peripheral circuit, with
And several buttons, the motor drive circuit and the phonation circuit are connected to the corresponding output end of the main control chip；
Also include acoustic control triggers circuit and lighting circuit, the outfan of the acoustic control triggers circuit is connected to the input of the main control chip
End, the lighting circuit are connected to the corresponding output end of the main control chip.
The power end of the main control chip connects the positive pole of the battery, the minus earth of the battery, the master control core
Piece has battery low pressure second hand stop signal output part, and this battery low pressure second hand stop signal output part is connected to the motor drive circuit
The control end of second hand drive motor.
A kind of movement control circuit of DCF radio wave clocks of the present utility model, is provided with acoustic control triggers circuit and lighting circuit, when
When acoustic control triggers circuit detects the decibel value of the sound (sound of such as clapping one's hands) in the external world more than setting value (such as 90dB), acoustic control triggering electricity
Road is started working, and output control signal sends control signal to lighting circuit by main control chip to main control chip, and lighting circuit is just
Light is sent, conveniently can be seen the time at night.
A kind of movement control circuit of DCF radio wave clocks of the present utility model, the electricity of main control chip real-time detection battery, when
When the electricity of battery is less than setting value, main control chip sends battery low pressure second hand stop signal and drives horse to the second hand of motor drive circuit
Reach, control second hand drive motor quits work, and reminds user more to renew battery as early as possible in the way of second hand stop pin.
Description of the drawings
