Abstract

The utility model aims at providing a single-chip-based electronic clock with a jowing function. The circuit is composed of a liquid crystal display module, a buzzer module, a single chip module and a control button module. The single-chip-based electronic clock with the jowing function is characterized in that the liquid crystal display module, the buzzer module and the control button module are respectively connected with a single chip; the model number of the liquid crystal display module is SMC1602a; the model number of the buzzer module is AD16; and the single chip selects 51 series AT89c51. The control button module comprises at least six buttons; and the time can be accurately measured, the circuit is simple and the electronic clock is easy to popularize in a large scale.

Description

The electronic clock that has the function of ringing a bell based on single-chip microcomputer

Technical field

The utility model relates to the single-chip microcomputer application, more particularly relates to the field that the Single-chip Controlling electronic clock is rung a bell.

Background technology

At present, the bell-ringing device that sell in market mainly has the function of ringing a bell, and without time showing, can not allow teacher student more can see when hearing, is after class in bell or the bell for class situation in case do not hear or do not know, brings unnecessary trouble.Present electronic clock just has the alarm clock timing function, the effect of can not continuous control going to school and leaving school and ringing a bell.In addition, the bell-ringing device on the market is expensive now, is not easy to the utilization and extention of remote school.

Summary of the invention

The purpose of this utility model provides a kind of electronic clock that has the function of ringing a bell based on single-chip microcomputer, can the precisive time, and circuit is simple, is easy to promote on a large scale.

The purpose of this utility model is achieved in that circuit by LCD MODULE, the hummer module, and one-chip computer module and control knob module form, and it is characterized in that: LCD MODULE, the hummer module links to each other with single-chip microcomputer respectively with the control knob module.The LCD MODULE model is: SMC1602A, hummer module model is: AD16, single-chip microcomputer select 51 series as: AT89c51.The control knob module is comprised of 6 buttons at least.The self-editing software program that meets the demands is embedded in the single-chip microcomputer.

Because adopt technique scheme, advantage and good effect that the utility model has are: accuracy of timekeeping is high, and circuit is simple, and price is low.

Description of drawings

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

Fig. 1 is schematic block circuit diagram of the present utility model.

Embodiment

With reference to figure 1, the utility model has the electronic clock 200 of the function of ringing a bell based on single-chip microcomputer, comprise LCD MODULE 2, hummer module 3, one-chip computer module 1 and control knob module 4, it is characterized in that: LCD MODULE 2, hummer module 3 links to each other with one-chip computer module 1 respectively with control knob module 4.Wherein control knob module 4 is provided with 5,6, and 10,11,12,13 buttons such as grade after button 5 is pressed, can pass through button 10,11,12,13 setup times, after button 6 is pressed, can be by 10,11,12,13 arrange one group rings a bell the time, again by a button 6, next group is set rings a bell the time, by that analogy, many groups can be set ring a bell the time.
