Description
Technical field
The utility model relates to Intelligent housing fields, and in particular to a kind of intelligence shutdown warning device.
Background technique
It is constantly progressive with the continuous development of society with scientific and technical, the especially featured intelligence control of electronic information technology
System, intelligence start to carry out popularizing in people's lives every aspect to come, and smart home is intelligently controlled as a modernization
System starts to popularize in people's lives household theory with the new concept that daily life is organically combined, the intelligence of household,
Hommization is increasingly significant.
The door of office, students' dormitory and family etc. is generally in closed state, and most of people are unwilling to open wide
Door, because not only dangerous but also be unfavorable for protecting individual privacy, many people paste the prompt poster of " shutting the door after you " on door, but
This method can not play the role of too big, and furthermore forgetting to shut the door after you causes the thing of some property losses to have in school dormitory
Occur, in addition doorbell controls, the control usually switched using manual switch, concrete operations are as follows: when needing to knock at the door
It waits, to find the position of doorbell on doorway, after finding doorbell, after pressing doorbell, doorbell is alarmed, and the people in room comes out and door is beaten
It opens；If it is night, doorway does not have electric light, and doorbell is not easily found, and cannot achieve comes out the people in room by doorbell
Door is opened；It if it is the people of a unhealthy obsession with cleanliness, does not like and is knocked at the door using doorbell, also cannot achieve is made in room by doorbell
People comes out and door is opened.Therefore, how to carry out more humanized design to door bell device is worth the problem of thinking deeply.
Summary of the invention
The purpose of the utility model is to provide a kind of structure is simple, intelligence shutdown warning device easy to use.
Purpose of the utility model is realized as follows:
A kind of intelligence shutdown warning device including door and positioned at the door and window of the header further includes buzzer, the door
The inside of window is equipped with the first photoelectric sensor, and the outside and inside of the door are respectively equipped with the second photoelectric sensor and fishing without hook, institute
State the top that fishing without hook is located at the inside of the door, the buzzer, first photoelectric sensor and second photoelectric sensing
Device is connect with single-chip microcontroller.
The single-chip microcontroller includes operational amplifier U1.
It is white at the top of the fishing without hook.
First photoelectric sensor includes infrared tube P1, is set on the infrared tube P1 there are four foot, and respectively the
One pin, second pin, third pin and the 4th pin.
First pin is connected by resistance R1 and switch S1 with positive pole, and the second pin and third pin connect
Power cathode is connect, the 4th pin is connected with the third output pin of operational amplifier U1, and the 4th foot passes through simultaneously
Two resistance R2 are connected with positive pole, and the first output pin of operational amplifier U1 is connected with the cathode of buzzer BZ1.
The side of second photoelectric sensor is equipped with the LED light for illumination.
The beneficial effects of the utility model are: the utility model structure is simple, the first photoelectric sensor and buzzer are set
It sets, can remind and shut the door after you in time, improve the working environment of people, the comfort level of living environment, satisfaction and safety, second
Photoelectric sensor is used as contactless doorbell, and convenient for reminding owner to open the door, the setting of LED light facilitates user at night
Find contactless doorbell.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the circuit diagram of the utility model；
In figure: door 1, door and window 2, the first photoelectric sensor 3, fishing without hook 4, the second photoelectric sensor 5.
Specific embodiment
Below in conjunction with attached drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of intelligent shutdown warning device, the door and window 2 including door 1 and positioned at 1 top of door,
It further include buzzer, the inside of the door and window 2 is equipped with the first photoelectric sensor 3, and the outside and inside of the door 1 are respectively equipped with the
Two photoelectric sensors 5, buzzer and fishing without hook 4, the fishing without hook 4 are located at the top of the inside of the door 1, are white at the top of the fishing without hook
Color, the buzzer, first photoelectric sensor 3 and second photoelectric sensor 5 are connect with single-chip microcontroller, and described second
The side of photoelectric sensor 5 is equipped with the LED light for illumination, and the single-chip microcontroller includes operational amplifier U1.
First photoelectric sensor 3 includes infrared tube P1, is set on the infrared tube P1 there are four foot, and respectively the
One pin, second pin, third pin and the 4th pin, first pin pass through resistance R1 and switch S1 and positive pole phase
Even, the second pin connects power cathode with third pin, and the third output of the 4th pin and operational amplifier U1 is drawn
Foot is connected, and the 4th foot passes through second resistance R2 simultaneously and is connected with positive pole, the first output pin of operational amplifier U1
It is connected with the cathode of buzzer BZ1.
When door 1 is closed, it is infrared that infrared tube P1 detects that the plate by 4 top white of fishing without hook of own transmission is reflected back
Light exports high level through the first output pin of operational amplifier U1, then buzzer is not rung；After door 1 is opened, due to there is no object
Product block the infrared light of infrared tube P1 sending, and infrared tube P1 can not receive the infrared light of own transmission, through operation
The first output pin of amplifier U1 exports low level, then buzzer rings, while the period being arranged on single-chip microcontroller, on daytime
6:00-23:00 this period, when input is that high level just starts to drive buzzer sending prompting sound after lasting enabling 20s；Such as
Fruit is late-late this period 23:00- next day 6:00, and when buzzer receives high level, just the sending duration 3 divides at once
The emergency alarm of clock.When interior needs to divulge information, the buzzer of system is closed by switch S1.
It is no longer superfluous herein since the circuit diagram of the second photoelectric sensor 5 is identical as the circuit diagram of the first photoelectric sensor 3
It states, the second photoelectric sensor 5 is fixed on the outside of door 1, when the second photoelectric sensor 5 detection someone is closely close, just sends out
Doorbell voice prompt out, the side of second photoelectric sensor 5 are equipped with the LED light for illumination, user are facilitated to look at night
To the position of contactless doorbell.
The utility model structure is simple, and the setting of the first photoelectric sensor and buzzer can be reminded in time and be shut the door after you, mention
Working environment, the comfort level of living environment, satisfaction and the safety of high people, the second photoelectric sensor is as contactless doorbell
It uses, convenient for reminding owner to open the door, the setting of LED light facilitates user to find contactless doorbell at night.
