Abstract

The invention discloses an intelligent household door based on a 51 single-chip microcomputer. A photoresistor is installed above a door frame to detect intensity of light so as to judge it is day or night. A reed switch is installed on one side surface of the door frame. One side surface of the door, opposite to the reed switch, is provided with a permanent magnet. Whether the door is opened or not is detected. By the use of the non-contact switch, abrasion is avoided when the door is opened or closed. High-brightness LED lights are mounted on the upward side of the door frame. The single-chip microcomputer controls the lights to be turned on at night when the door is opened and be automatically turned off after 30 seconds. A buzzer is mounted on the door frame and will give an alarm if the householder forgets to close the door at night. Thus, the purpose of energy conservation and intelligentization is achieved.

Description

Smart Home door

Technical field:

The present invention relates to a kind of Smart Home door based on 51 single-chip microcomputers, in the time that darkness door is opened, on doorframe, can automatically light LED lamp, facilitate owner to find the switch of family lamp, and LED lamp can automatic distinguishing, not closing for a long time visits also can send warning reminding owner and shut the door.

Background technology:

Current existing Household door adopts light-operated switch with the photosensitive-member of illumination functions, this type of switch hardware circuit complexity, and part category used is many; What the switch whether detection opens the door adopted is travel switch, and this switch belongs to touch switch, opens the door at every turn, all can contact with door at closing time, and the time has been grown and just there will be wearing and tearing, has reduced useful life; After gate light is bright, need manual-lock, and without the prompting function of forgetting to close the door, energy saving and intelligent degree are all inadequate.

Summary of the invention:

In order to overcome existing Household door gate light light-operated circuit complexity, switch is easy to wear, problem and defect that energy saving and intelligent degree are not high, the object of the invention is openly a kind of Smart Home door based on 51 single-chip microcomputers, it is characterized in that adopting simple photo-sensitive cell photo resistance and non-contact switch tongue tube, on opening the door rear door frame night, can automatically light LED lamp, and can automatic distinguishing, owner forgets to close the door also can remind it evening.

The technical solution adopted for the present invention to solve the technical problems is: it is daytime or evening with judgement that photo resistance is contained in doorframe top detection light intensity, the common emitter transistor switching circuit of its composition is very simple, and transistor collector connects an input port of single-chip microcomputer; Tongue tube is contained in the side of doorframe, with tongue tube just right door side mounting permanent magnet, this non-contact switch can not produce wearing and tearing in the time of door switch, dry-reed tube switch circuit connects another input port of single-chip microcomputer; High-brightness LED lamp is arranged on the top of doorframe, and circuit connects a delivery outlet of single-chip microcomputer.In the time that single-chip microcomputer detects that two input ports are all high level, just can send low level to delivery outlet, make high-brightness LED lamp light, Single-chip Controlling high-brightness LED lamp is automatic distinguishing after 30 seconds.Now whether detecting gate is still opened again, and if so, buzzer sends warning, reminds owner to shut the door, and reaches energy-conservation and intelligentized object.

The invention has the beneficial effects as follows: photographic department parallel circuit is simple, the switch whether detecting gate is opened is contactless, can be because the switch of door weares and teares, and meeting automatic distinguishing after bright a period of time of gate light, and owner forgets close the door and can also remind evening, energy saving and intelligent degree are high.

Embodiment:

Below in conjunction with embodiment, the invention will be further described:

As shown in Figure 1, a kind of Smart Home door based on 51 single-chip microcomputers, comprises core control section, the test section of opening the door, darkness test section, illumination section and warning part.

Core control section comprises: 51 single-chip microcomputers [1] and its hardware circuit [8] around.Two input ports of 51 single-chip microcomputers [1] receive the signal of being sent by open the door test section and darkness test section, determine whether to have opened at dark door, and if so, 51 single-chip microcomputers [1] light by the high-brightness LED lamp [7] of one delivery outlet control illumination section.

The test section of opening the door comprises: be fixed on tongue tube [4] on doorframe [6], be fixed on it just to the permanent magnet [3] on the door body [5] of position and hardware circuit [8] around.In the time that door body [5] is opened, permanent magnet [3] is removed thereupon, and tongue tube [4] is thrown off magnetic field range, just can conducting, signal is delivered to an input port of 51 single-chip microcomputers [1].

Darkness test section comprises: photo resistance [2] and around hardware circuit [8].Daytime with evening intensity of illumination different, photo resistance [2] resistance also can become light resistance (daytime, less) and dark resistance (evening, larger) thereupon, make triode conducting or shutoff in hardware circuit [8], signal is delivered to another input port of 51 single-chip microcomputers [1].

Illumination section comprises: be fixed on high-brightness LED lamp [7] and hardware circuit [8] on doorframe [6].In the time that 51 single-chip microcomputers [1] detect that darkness is opened the door, light by a delivery outlet control high-brightness LED lamp [7].51 single-chip microcomputers [1] are controlled high-brightness LED lamp [7] automatic distinguishing after 30 seconds.

The part of reporting to the police comprises: the buzzer [9] and the hardware circuit [8] that are fixed on [6] on doorframe.In the time that high-brightness LED lamp [7] extinguishes, whether the input-signal judging door of 51 single-chip microcomputers [1] detection tongue tubes [4] is shut, if do not shut, buzzer [9] sends warning.

Claims

1. the Smart Home door based on 51 single-chip microcomputers, is characterized in that: by 51 single-chip microcomputers [1], and photo resistance [2], permanent magnet [3], tongue tube [4], door body [5], doorframe [6], high-brightness LED lamp [7], hardware circuit [8], buzzer [9] forms, control whole gate light system by single-chip microcomputer [1], according to the resistance value size of photo resistance [2] and the conducting situation of tongue tube [4], 51 single-chip microcomputers [1] determine whether to beat at dark opening door body [5] by the low and high level that detects input port, if 51 single-chip microcomputers [1] are controlled opening of high-brightness LED lamp [7] by controlling its delivery outlet, and the time delay subroutine control high-brightness LED lamp [7] that passes through 51 single-chip microcomputers [1] was at 30 seconds automatic distinguishings, now 51 single-chip microcomputers [1] detect the signal that tongue tube [4] is sent here again, if decision gate body [5] does not shut, 51 single-chip microcomputers [1] are controlled buzzer [9] warning reminding owner and are closed the door by controlling its delivery outlet, thereby realize Based Intelligent Control and energy-conservation effect.
