Description
Technical field
This utility model relates to a kind of classroom lectern, particularly to a kind of classroom lectern with timing automatic prompting function.
Background technology
School goes to school and leaves school at present, purchase special timer to ring a bell, and general teaching building installs one, what teaching building was bigger is probably one layer of installation one, but loudspeaker go wrong sometimes, sound is less or does not has the tinkle of bells etc. weekend, affects normal order in education, the such as play time arrives, the tinkle of bells is little or does not has the tinkle of bells, causes teacher to prolong a class, and causes being discontented with of student；In four or six grades of examinations, arrangement of time is compact, and the time somewhat arranges unreasonable, and exercise question just cannot not do completely, but supervisor can not remind in the moment, and also simply examination starts the tinkle of bells and examination terminates to ring.
Utility model content
In order to overcome some problems of above-mentioned existence, the purpose of this utility model is to provide a kind of classroom lectern with timing automatic prompting function, facilitates the normal order in education of specification and reminds examinee's time on time.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that
A kind of classroom of this utility model lectern with timing automatic prompting function, including lectern body, power module and main control module, described power module and main control module may be contained within lectern, and this is internal, the intrinsic left side of described lectern is provided with at least one supply socket, described supply socket and power module electrical connection, described power module and main control module electrical connection, described main control module includes singlechip controller, described singlechip controller respectively with loudspeaker, display screen and function button electrical connection, described singlechip controller includes timer, loudspeaker can be controlled by the described singlechip controller of setting at the appointed time to work.
Further, described singlechip controller is AT89C51 chip.
Further, loudspeaker are electrically connected with singlechip controller by drive circuit, and described drive circuit includes being sequentially connected in series the audion of electrical connection, fly-wheel diode, filter circuit.
Further, described supply socket, display screen and function button are positioned at the left side outer wall of described lectern body, and described power module and main control module are respectively positioned on the inner left wall of described lectern body.
Further, described power module includes that 5V direct-current voltage reducing circuit drops in the alternating voltage 220V fall 36V step-down rectifying circuit being connected in series and 36V, wherein 220V fall 36V step-down rectifying circuit includes that transformator and the rectifier bridge stack being connected in series, 36V fall 5V direct-current voltage reducing circuit include LM7805 chip.
Compared with prior art, Advantageous Effects of the present utility model:
Can send prompting in the time of going to school and leaving school, in large-scale examination, time segment is automatically reminded to examinee, in order to the normal order in education of specification and on time prompting examinee's time energy-conserving and environment-protective；Simple in construction, easy to use, it is easy to promote.
Accompanying drawing explanation
The utility model is described in further detail in explanation below in conjunction with the accompanying drawings.
Fig. 1 is a kind of classroom of this utility model structural representation with the lectern with timing automatic prompting function；
Fig. 2 is this utility model power module schematic diagram.
Description of reference numerals: 1-lectern body；2-supply socket；3-power module；4-main control module；41-singlechip controller；42-loudspeaker；43-display screen；44-function button.
Detailed description of the invention
As it is shown in figure 1, a kind of classroom lectern with timing automatic prompting function includes lectern body 1, power module 3 and main control module 4；Left side in described lectern body 1 is provided with at least one supply socket 2, can be 2,3 or 4；Supply socket 2 can be used to mobile phone charging, supply socket 2 and power module 3 electrically connect, power module 3 and main control module 4 electrically connect, main control module 4 includes singlechip controller 41, singlechip controller 41 electrically connects with loudspeaker 42, display screen 43 and function button 44 the most respectively, singlechip controller 41 includes AT89C51 chip, inside has timer；Loudspeaker 42 connect singlechip controller 41 by drive circuit, audion that drive circuit includes being connected in series, fly-wheel diode, filter circuit；Supply socket 2, display screen 43 and function button 44 are positioned at the left side outer wall of lectern body 1, power module 3 and main control module 4 and are respectively positioned on the inner left wall of lectern body 1.
Referring to the drawings shown in 2, described power module includes that 5V direct-current voltage reducing circuit drops in the alternating voltage 220V fall 36V step-down rectifying circuit being connected in series and 36V, wherein 220V fall 36V step-down rectifying circuit includes that transformator and the rectifier bridge stack being connected in series, 36V fall 5V direct-current voltage reducing circuit include LM7805 chip.
Power module 3 is that singlechip controller 41, loudspeaker 42, display screen 43 and function button 44 are powered.
During use, by keypress function on singlechip controller 41, function button 44 is used for setting the time, and display screen 43 is for showing the time of setting, so after the time after class arrives the time that timer sets, singlechip controller 41 output signal will drive loudspeaker 42 to send sound；Or in examination process, arranging the time (such as half an hour) again by function button 44, so after it's half an hour has past the time, singlechip controller 41 output signal will drive loudspeaker 42 send sound afterwards.
This utility model can send prompting in the time of going to school and leaving school, and in large-scale examination, time segment is automatically reminded to examinee, in order to the normal order in education of specification and on time prompting examinee's time；The left surface outer wall of lectern, equipped with supply socket 2, can facilitate mobile phone to charge.Simple in construction, easy to use, it is easy to promote.
