Abstract
The utility model discloses the quarts wall clock structure of automatic mute at a kind of night, comprise crystal clock body and power supply thereof, a display alphanumeric data and time isoparametric liquid crystal indicator is provided with in the display dial of crystal clock body, liquid crystal indicator connects a MCU controller, MCU controller connects the stepper motor driving circuit of a light luminance testing circuit and a driving crystal clock body pointer running again, stepper motor driving circuit connects stepper motor, and driving stepper motor connects the hour hands of crystal clock body, minute hand and second hand; When the utility model crystal clock enters automatic mute mode of operation night, MCU controller control step motor shuts down, does not send mechanicalness noise, and send corresponding quiet instruction, when recovering on crystal clock daytime to run well, pointer is by can with time calibration of showing in liquid crystal indicator and synchronous operation, night can be completely quiet, can reply again pointer that people are accustomed to checking daytime when walking.
Description
Technical field
The utility model relates to quarts wall clock technical field, particularly relates to the quarts wall clock structure of automatic mute at a kind of night.
Background technology
Quarts wall clock is people's timing tools used in everyday, checks time intuitive and convenient, but its exists a larger defect: during the electronic clock running of mechanical running gear relatively, machinery noise ratio is larger; Even be the quarts wall clock of very high-grade precision, mechanical drive sound ticking, ticking during running is also larger, and particularly at night, under environment in the dead of night, its mechanicalness noise is relatively outstanding, is unfavorable for that consumer uses.In order to improve the shortcoming of prior art quarts wall clock, need to develop the Novel quartz wall clock that can not send operating sound night.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides a kind of night can automatic mute, quarts wall clock structure that daytime, pointer normally indicated.
The utility model for the technical scheme reaching above-mentioned technical purpose and adopt is: a kind of night automatic mute quarts wall clock structure, comprise crystal clock body and power supply thereof, a display alphanumeric data and time isoparametric liquid crystal indicator is provided with in the display dial of described crystal clock body, described liquid crystal indicator connects a MCU controller, described MCU controller connects a light luminance testing circuit again, the stepper motor driving circuit of a described MCU controller control linkage driving crystal clock body pointer running, described stepper motor driving circuit connects stepper motor, described driving stepper motor connects the hour hands of crystal clock body, minute hand and second hand, light luminance testing circuit is utilized to detect crystal clock current whether evening or daytime, when detecting that crystal clock runs at night, enter automatic mute mode of operation at night, MCU controller control step motor shuts down, does not send mechanicalness noise, the time simultaneously shown in liquid crystal indicator is normal operation, and a quiet mark is increased on liquid crystal indicator interface, remind user whether to start automatic mute state at night, when detecting that crystal clock runs by day, MCU controller control step motor starts to recover to run well, when recovering to run well, pointer is controlled by MCU controller, according to the time data of MCU controller storage inside memory, can with time calibration of showing in liquid crystal indicator and synchronous operation.
Described crystal clock body is also provided with a quiet LED light, described quiet LED light is connected with MCU controller.
Described light luminance testing circuit is photoresistance testing circuit.
Described stepper motor comprises three stepper motors driving hour hands, minute hand and second hand respectively.
The beneficial effects of the utility model are: adopt said structure, in conjunction with MCU microprocessing, the technology such as photoresistance detection technique and step motor transmission, directly utilize storer data storage time in MCU controller, control the stepper motor running and the liquid crystal indicator display word time that drive the running of quartz clock movement pointer, when crystal clock enters automatic mute mode of operation night, MCU controller control step motor shuts down, do not send mechanicalness noise, and send corresponding quiet instruction, during crystal clock recovery on daytime normal operation, pointer is controlled by MCU controller, can with time calibration of showing in liquid crystal indicator and synchronous operation, can can be completely quiet when people need peace and quiet, pointer that people are accustomed to checking can be replied again when walking during normal operation, be particularly suitable for having the timing in night of requirement to use to noise.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.Wherein:
Fig. 1 is the theory diagram of the quarts wall clock structure of the utility model automatic mute at night;
