Abstract

Disclosed is an intelligent household door based on a 51 single-chip microcomputer. A photoresistor is installed on the top of a door frame and detects the intensity of light, so as to judge that it is daytime or nighttime. A reed pipe is installed at a side of the door frame. A side, opposite to the reed pipe, of a door is equipped with a permanent magnet, so as to detect whether the door is open or not. The non-contact opening-closing mode cannot generate abrasion during the opening/closing of the door. High-brightness LED lamps are installed on the top of the door frame. The single-chip microcomputer controls the LED lamps to light during the opening of the door in nighttime, and the LED lamps automatically turn off after 30 seconds. A buzzer is installed on the door frame, and gives an alarm to remind a master if the master forgets to close the door in nighttime, thereby achieving the purposes of energy saving and intelligentization.

Description

A kind of Smart Home door based on 51 single-chip microcomputers

Technical field:

The utility model relates to a kind of Smart Home door based on 51 single-chip microcomputers, when the darkness door is opened, can automatically light the LED lamp on doorframe, facilitate owner to find the switch of family lamp, but and LED lamp automatic distinguishing, long-time do not close to visit also can send the 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; Need manual-lock after gate light is bright, 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 purpose of this utility model is to disclose a kind of Smart Home door based on 51 single-chip microcomputers, it is characterized in that adopting photo resistance, triode, single-chip microcomputers etc. form hardware circuit, and tongue tube and magnet coordinate as the non-contact detection switch, can automatically light the LED lamp on opening the door rear door frame night, and can automatic distinguishing, owner forgets to close the door also can be reminded 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 over against the door the side mounting permanent magnet, this non-contact switch can not produce wearing and tearing when door switch, the 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.When single-chip microcomputer detects two input ports and all is high level, just can send low level to delivery outlet, make high-brightness LED lamp light, the Single-chip Controlling high-brightness LED lamp is automatic distinguishing after 30 seconds.Now whether detecting gate is still opened again, if buzzer sends warning, reminds owner to shut the door, and reaches energy-conservation and intelligentized purpose.

The invention has the beneficial effects as follows: the photographic department parallel circuit is simple, the switch whether detecting gate is opened is contactless, can not wear and tear because of the switch of door, and gate light is the meeting automatic distinguishing after bright a period of time, 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, comprise the core control section, the test section of opening the door, darkness test section, illumination section and warning part.

The core control section comprises: 51 single-chip microcomputers [1] and the hardware circuit [8] around it.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, if the high-brightness LED lamp [7] that 51 single-chip microcomputers [1] are controlled illumination section by the one delivery outlet lights.

The test section of opening the door comprises: be fixed on tongue tube [4] on doorframe [6], be fixed on it over against the permanent magnet [3] on the door body [5] of position and hardware circuit [8] on every side.When door body [5], while being 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].

The darkness test section comprises: photo resistance [2] and hardware circuit [8] on every side.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].When 51 single-chip microcomputers [1] detect darkness and open the door, control high-brightness LED lamp [7] by a delivery outlet and light.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.Whether when the input-signal judging door of high-brightness LED lamp [7] 51 single-chip microcomputers [1] detection tongue tubes [4] while extinguishing, 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 51 single-chip microcomputers [1], determine whether to beat at dark opening door body [5] according to the resistance value size of photo resistance [2] and the conducting situation of tongue tube [4], if 51 single-chip microcomputers [1] are controlled opening of high-brightness LED lamp [7] by controlling its delivery outlet, and after 30 seconds automatic distinguishing, 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 energy-conservation and effect Based Intelligent Control.
