Abstract
The utility model discloses an electronic clock multistage sets up formula alarm clock, including MCU, emitting diode L, resistance R and loudspeaker S, MCU connects emitting diode L's negative pole, key switch SET, key switch UP, key switch DOWN, key switch STSP, loudspeaker S and LCD display screen respectively, emitting diode L's positive pole connecting resistance R, and key switch SET's the other end, key switch UP's the other end, key switch DOWN's the other end, key switch STSP's the other end and power VDD are connected to resistance R's the other end. The utility model discloses electronic clock multistage sets up formula alarm clock has following advantage: 1, the realization can every day, singly stop, twoly stop, saturday, sunday are independently rung a bell. 2, set up opening and closing of a plurality of time points of ringing a bell. 3, ring a bell workday and ring a bell inoperative day if any setting up. 3, the time quantum can switch in the quick closedown, and when ringing a bell, also the accessible button stops at once. 4, set up time, high efficiency, quick are practiced thrift in disposable adjustment.
Description
Technical field
This practical quarter-bell relating to liquid crystal clock and watch class working day and nonworkdays is arranged.Simultaneously multiple time point of ringing a bell can be set, realize every day, singly to stop, twoly to stop, Saturday, Sunday independently ring a bell.Arrange rear multiple time point of ringing a bell to open and close by button.By microprocessor detect alarm time.Output is rung a bell signal.The electronic technology field that realization is repeatedly rung a bell and the quarter-bell technological improvement to existing alarm clock.
Background technology
Owing to having now the electronic clock arranging the time of ringing a bell on the market, all have the function regulating the time of ringing a bell, what can arrange is generally three groups of quarter-bells.When people arrange the good quarter-bell of quarter-bell.It is actually bell of all quarrelling and fighting noisily every day, or MONDAY to FRIDAY is rung a bell, or Monday rang a bell to Saturday.But actual people live, requirement is multifarious, and everyone is except while reminding between operationally.Also to remind in the time period of inoperative.For an existing electronic clock being provided with quarter-bell on the market, it can ring once in (as front 7 points of the going to work) set time every day, or at the fixing sound of MONDAY to FRIDAY (as front 7 points of going to work), or fix sound Monday to Saturday (as front 7 points of going to work).If want independent on Saturday or Sun., (as at 10 points) will remind time, can only the time be reset.After having reminded, again the working time is before arranged again.Affect the use of user to product.
Existing electronic clock, all not to arranging separately on Saturday or Sunday, makes user can be very inconvenient when nonworkdays will be reminded, when not having above-mentioned setting.User can only change over the nonworkdays time period the time period on working day arranged before, then readjusts the time.After completing quarter-bell Deng this time point.The original working time is set back again.
Utility model content
The purpose of this utility model is to provide a kind of electronic clock multistage to arrange formula alarm clock, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of electronic clock multistage arranges formula alarm clock, comprise MCU, light emitting diode L, resistance R and loudspeaker S, described MCU is the negative electrode of connecting luminous diode L, keyswitch SET, keyswitch UP, keyswitch DOWN, keyswitch ST/SP, loudspeaker S and LCD display respectively, the other end of the other end connection keyswitch SET of the anode contact resistance R of light emitting diode L, resistance R, the other end of keyswitch UP, the other end of keyswitch DOWN, the other end of keyswitch ST/SP and power vd D.
As preferred version of the present utility model: described power vd D is 3V-4.5V battery.
Compared with prior art, the beneficial effects of the utility model are: the utility model electronic clock multistage arranges formula alarm clock and has the following advantages: 1, realize can every day, single to stop, twoly to stop, Saturday, Sunday independently ring a bell.2, the opening and closing of multiple time point of ringing a bell are set.3, to ring a bell working day and nonworkdays is rung a bell if any arranging.3, the time period can switch in quick closedown, when ringing a bell, also stops at once by button.4, disposable adjustment, saves setup times, efficient, fast.
Accompanying drawing explanation
Fig. 1 is the circuit diagram that electronic clock multistage arranges formula alarm clock.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of electronic clock multistage arranges formula alarm clock, comprise MCU, light emitting diode L, resistance R and loudspeaker S, described MCU is the negative electrode of connecting luminous diode L, keyswitch SET, keyswitch UP, keyswitch DOWN, keyswitch ST/SP, loudspeaker S and LCD display respectively, the other end of the other end connection keyswitch SET of the anode contact resistance R of light emitting diode L, resistance R, the other end of keyswitch UP, the other end of keyswitch DOWN, the other end of keyswitch ST/SP and power vd D.
Power vd D is 3V-4.5V battery.
Principle of work of the present utility model is: being and having and can arrange multiple time point of ringing a bell described by the utility model, realizes every day, singly to stop, twoly to stop, Saturday, Sunday independently ring a bell.The opening and closing of multiple time point of ringing a bell are set.By microprocessor detect alarm time.Output is rung a bell signal.The electronic technology field that realization is repeatedly rung a bell and the device to alarm clock quarter-bell.Comprise single-chip microcomputer, liquid crystal display, detected electrons clock export the circuit of signal of ringing a bell, and wherein liquid crystal display adopts LCD display, by the connection of single-chip microcomputer and circuit.Make it have multiple time point of ringing a bell, realize every day, single to stop, twoly to stop, Saturday, Sunday independently ring a bell and can open and close fast and often organize quarter-bell.Single-chip microcomputer, to LCD display output display signal, can detect the time of ringing a bell simultaneously.By the time point set, judge whether to ring a bell.Thus output signal controls loudspeaker B jingle bell, can see the time at night; In the process of ringing a bell, there is a key only noisy function, press next key only noisy key, the stopping of bright light can ring a bell, within the 2nd day simultaneously, normally can ring noisy according to the setting same time.
Claims (2)
