Abstract

The utility model relates to an intelligent alarm device, comprising a strong-vibration sensor, a micro-vibration sensor, a touch sensor, a switch sensor which is arranged at the side of a door, a single-chip computer (a CPU processor) which receives, analyzes and processes information from all sensors, a logic-control unit which locks and unlocks alarm output signals from the single-chip computer and the strong-vibration sensor, an alarm-signal output device which sends alarm signals from the logic-control unit to a control center, and an on-site alarm device which directly receives results which are analyzed and processed by the single-chip computer. The device has the functions of automatic guard arrangement, guard withdraw, normal door opening, and automatic guard arrangement in thirty seconds after automatic guard withdraw and door closing. All functions are very convenient for users.

Description

The intelligence alarm device

The utility model relates to a kind of intelligent alarm device, and particularly a kind of Intelligent Recognition is normally opened the alarm device of door and unauthorised broken door.

It is one of a kind of effective ways of taking for the safety precaution that strengthens resident family in the safe protection engineering that the dwelling house door installs the electronic alerts device additional.The door dress alarm device of domestic production at present or use has installation, changes inconvenience, needs and the lock interlock; Use inconveniently, deploying troops on garrison duty and withdrawing a garrison needs use code keypad, or cipher remote control device or magnetic card, and this is very inconvenient to the family that old man, child are arranged, and easily generation is forgotten to deploy troops on garrison duty and failed to report the police, or forgets the generation false alarm of withdrawing a garrison.Adopt the simple vibration transducer rate of false alarm can be very high.

The purpose of this utility model provides a kind of intelligent alarm device that can lock interlock to human body sensing information, little vibration information of unblanking, the identification of impact damage information intelligent and independent installation discord.

The utility model comprises strong vibration sensor, vibrative sensor, touch sensor and Men Bian switch sensor, reception and analyzing and processing are from the single-chip microcomputer (CPU processor) of each sensor information, to the logic control element of report to the police from the alarm output signal of single-chip microcomputer and strong vibration sensor locking and unlatching, will send the alerting signal output unit and the direct onsite alarming device that receives the single-chip microcomputer analysis processing result of control center from the alerting signal of logic control element.Strong vibration sensor (1), vibrative sensor (2), touch sensor (3) and door limit switch sensor (4) link to each other with the input end of single-chip microcomputer (5), the output terminal of single-chip microcomputer (5) is leaded up to logic control element (6) signal output apparatus taking alarm (7), and another road connects onsite alarming device (8).

Described strong vibration sensor (1) also directly links to each other with logic control element (6).

Described logic control element (6) is by two inputs and door IC ₃, IC ₅With two inputs or door IC ₄Form.

Described onsite alarming device (8) is by power amplifier IC ₉Form with loudspeaker; Triode N ₁Constitute alerting signal output unit (7) with relay J.

The utlity model has the function of very deploying troops on garrison duty automatically easily, withdraw a garrison, and normal door, withdraw a garrison automatically and close the function of deploying troops on garrison duty automatically for 30 seconds behind the door the user.

Below in conjunction with accompanying drawing the utility model is specifically described.

Fig. 1 is circuit theory diagrams of the present utility model.Fig. 2 is the physical circuit figure of Fig. 1.

Referring to Fig. 1, the utility model comprises the identification collision or destroys the strong vibration sensor 1 of door, the vibrative sensor 2 of the vibration signal that identification is sent when unblanking, the door limit switch sensor 4 of identification human-induced signal's touch sensor 3 and identification enabling signal, single-chip microcomputer (CPU processor) 5 receptions and analyzing and processing are from the information of four sensors, report to the police locking and open to handle of 6 pairs of alarm output signals of logic control element from single-chip microcomputer 5 and strong vibration sensor 1, be sent to alerting signal output unit 7 for the alerting signal logic control element, the alerting signal output unit send control center with it again.The utility model also comprises an onsite alarming device 8 that directly receives the single-chip microcomputer analysis processing result.This intelligence alarm device is installed discord lock interlock separately.

IC ₁Single-chip microcomputer 87C51 is the core of circuit, finishes computing and control function.IC2 double operational LM3558.IC2A and resistance R ₁, R ₂, R ₃, R ₄, R ₅, R ₆, capacitor C ₃, C ₅Diode D ₁Form the vibrating sensing circuit.R ₄, R ₅, D ₁, C ₃Be integrating circuit, the about 1S of integration constant realizes that the strong vibration signal amplifies.R ₆, C ₅The about 0.1S of integration constant realizes that micro-vibration signal amplifies, and two signals send A/D converter IC respectively ₆IC ₆Be 8 road A/D converter ADC0809.IC2B and resistance R ₇, R ₈, R ₉Constitute the human body sensing amplifier, amplifying signal send A/D conversion.IC ₇, IC ₈Be frequency divider, provide ADC0809 sampling clock to 640KHZ and 4KHZ the 8MHZ oscillation signal frequency dividing.IC ₃, IC ₅Be two inputs and door, IC ₄Be two inputs or door, IC ₃, IC ₄, IC ₅Constitute the simple logic control module, logic control is carried out in alarm output signal, warning locking, unlatching.IC ₉Be power amplifier, IC ₉And loudspeaker, constitute the onsite alarming device, N ₁With relay J, constitute the warning output unit, the alert control center of delivering newspaper.

Principle of work of the present utility model is as follows:

When normal unlatching door, the human-induced signal is arranged, after single-chip microcomputer receives this signal, next step judges vibration signal, can produce little vibration when opening the lock with the key, and single-chip microcomputer judges it is the vibration signal of unblanking through computing, pick up counting, send out the ticking prompting behind the 15S, after 30 seconds, open as door and to be considered as normal door, otherwise think unauthorised broken, send out the alert signal that shakes, when door is met strong bump, judge it is when destroying the bump signal of door behind the 2S through the single-chip microcomputer computing, the alert signal of transmitting messages.

The normal door of opening spreads anti-ly automatically, closes 30 seconds behind the door, sets up defences automatically.
