Abstract
The utility model discloses a kind of burglar alarm, including door, handle mounted on a door and lock core, also include being arranged on the light sensor below outer side of door, lock core, it is arranged on power supply and the switch of an inner side, and infrared ray sensor, voice guard and the microcontroller being arranged in door on passageway；Described switch electrically connects with power supply, and described switch, infrared ray sensor, light sensor, voice guard electrically connect with microcontroller respectively.This utility model is provided with alarm device, at night, if there being stranger to make a forcible entry into or to come within doors, alarm device will be triggered, thus sends alarm sound, has effectively reminded owner within doors, it is to avoid the loss of house owner.
Description
Technical field
Specifically a kind of burglar alarm of this utility model, belongs to electronic technology field.
Background technology
Along with the development of society, present residential quarter is substantially all equipped with security personnel and monitor and control facility, and public security is relatively good a lot, but still cannot stop the appearance of thief.Owing to there is security personnel's handle on doorway, community on daytime, and monitoring on daytime is more clear, so thief can commit a crime morning, people sleep soundly when, and major part is to be directly entered indoor theft by unblanking, and people, when sleeping soundly, are difficult to discovery indoor stolen.
Summary of the invention
The purpose of this utility model is to provide a kind of burglar alarm, it is possible to effectively reminds house owner indoor to have stranger will to make a forcible entry into or come into, thus avoids loss for house owner.
For achieving the above object, this utility model one burglar alarm, including door, handle mounted on a door and lock core, also include being arranged on the light sensor below outer side of door, lock core, it is arranged on power supply and the switch of an inner side, and infrared ray sensor, voice guard and the microcontroller being arranged in door on passageway；Described switch electrically connects with power supply, and described switch, infrared ray sensor, light sensor, voice guard electrically connect with microcontroller respectively.
Preferably, described light sensor is photoconductive resistance.
Preferably, described voice guard is buzzer or music player.
Further, also include that visual alarm, described visual alarm are LED flashing lamp.
Compared with prior art, this utility model is provided with alarm device, at night, if there being stranger to make a forcible entry into or to come within doors, alarm device will be triggered, thus sends alarm sound, has effectively reminded owner within doors, it is to avoid the loss of house owner.
Accompanying drawing explanation
Fig. 1 is this utility model overall structure schematic diagram；
Fig. 2 is this utility model electricity block diagram.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, this utility model one burglar alarm, including door 6, the handle 7 being arranged on door 6 and lock core 8, also include the light sensor 9 being arranged on outside door 6, below lock core 8, it is arranged on power supply inside door 64 and switch 5, and infrared ray sensor 1, voice guard 2 and the microcontroller 3 being arranged in door 6 on passageway；Described switch 5 electrically connects with power supply 4, and described switch 5, infrared ray sensor 1, light sensor 9, voice guard 2 electrically connect with microcontroller 3 respectively.
As this utility model optimal way to technique scheme, described light sensor 9 is photoconductive resistance, simple in construction, and low cost.
As this utility model optimal way to technique scheme, described voice guard 2 is buzzer or music player.
As this utility model improvement to technique scheme, also including visual alarm 10, described visual alarm 10 is LED flashing lamp, can be while chimes of doom sends, and LED flashes, the most eye-catching at night.
Work process: open switch 5, power supply 4 is connected, at night, when having thief to need to be entered within doors by door, owing to light is dark, need to observe lock core 8 by the light of pocket lamp, thus carry out technology unlocking, owing to being provided with light sensor 9 below lock core 8, while thief illuminates lock core 8 with pocket lamp, light sensor 9 feels high light, high light signal is sent to microcontroller 3, after microcontroller 3 receives signal, control voice guard 2 and send chimes of doom, remind in time and have thief to unblank by force outside owner's door 6 within doors, house owner can select to check in time or report to the police.If door 6 is opened by thief, then thief enters within doors, and the infrared ray sensor 1 installed on passageway in door 6 senses that someone enters after in induction range, transmits a signal to microcontroller 3, after microcontroller 3 receives signal, controlling visual alarm 10 to light, voice guard 2 does not release simultaneously, continuously sends out chimes of doom, again remind house owner, thief has been enter within doors, makes house owner find thief in time, thus avoids or reduce loss.
When daytime family have people, it is not necessary to enable this utility model, will switch 5 closedown, deenergization 4.The antitheft coefficient of this utility model is higher, and simple in construction, it is easy to manufacture, low cost of manufacture.
