Description

Silencing alarming device

The mute type alarm device relates to a kind of burglar alarm, belongs to antitheft equipment field.

Present anti-theft device normally is installed in to be needed on the antitheft article or near it, in case the burglar touches article or enters antitheft zone, anti-theft device promptly sends the high-decibel alarm song, the shortcoming of this burglar alarm is, the people who is strayed into antitheft zone or involuntary touch article there is not warning, the same warning, concentrate as present unban population, vehicle often takies the walkway and parks, after the pedestrian runs into automobile because of carelessness, alarms and security systems for automobiles is promptly reported to the police, cause unnecessary noise to disturb, when this external operation car alarm or indoor alarm, because unavoidable misoperation or external interference also can produce wrong report, the noise that these wrong reports produce causes user and neighbours' puzzlement, also is the new environmental issue that occurs in recent years.In addition, the burglar deliberately triggers alarm device sometimes and reports to the police, harassing and wrecking user and neighbours' peacefulness, being confused about alarm device is under wrong report or true thief's the situation on earth, user's warning system of most likely dismantling so just produced antitheft leak, so that the burglar commits theft.

The purpose of this utility model provides a kind of can repeatedly the warning, can prevent ruined mute type alarm device itself again.

The utility model realizes that as follows it comprises microcomputer controller and parts such as counter, phonetic memory device, voltage stabilizer, voice expander and hummer thereof.Voltage stabilizer provides operating voltage for microcomputer controller and phonetic memory device.Counter is arranged in the microcomputer controller, three input pins are respectively IN, KEY and SIN, internal counter output behind 5 volts of voltages of input pin IN input, behind 5 volts of voltages of input pin KEY input, start then whether inner detecting input pin SIN is positive voltage, if positive voltage, then internal counter output, one microswitch is installed between input pin SIN and positive voltage, microcomputer controller has the output of three parts, and output pin NO is connected with relay after transistor amplifies, and relay is controlled another warning or control device, output pin OUT is connected with hummer after transistor amplifies, and output pin A0-A14 reaches Be connected with the phonetic memory device, the broadcast of control voice, the phonetic memory device is connected with the voice expander, connects the loudspeaker playback behind the expander.

During use, the input pin IN and the voltage stabilizer input of microcomputerized control are connected with alarm, alarm is found promptly automatically 5 volts of positive voltages to be imported input pin IN behind the robber, microcomputer controller work, control phonetic memory device is play first of warning voice content, voice amplify the back by the loudspeaker playback, at interval after 15 seconds, when if input pin IN still imports positive voltage, microcomputer controller control phonetic memory device is play second, after at interval 30 seconds, if when input pin IN still imports positive voltage, microcomputer controller control phonetic memory device play the 3rd three times, microcomputer controller output pin OUT exports a pulsating wave driven high-decibel hummer and sends and drink resistance sound then, the positive voltage of output pin NO output simultaneously promotes relay work, and relay is controlled other device work.The another kind of mode of using is that the input pin KEY with microcomputer controller connects 5 volts of positive voltages, whether the input pin of the inner detecting of microcomputer controller at this moment SIN is positive voltage, promptly enter the antitheft state of alert, if there is the burglar to vibrate this alarm device, microswitch between input pin SIN and 5 volts of voltage sources can produce of short duration closure, input pin SIN can import 5 volts of voltages, microcomputer controller work, counter output, and control phonetic memory device work, play continuously the 3rd of voice content three times, output pin OUT exports a pulse wave electric voltage and drives hummer and send and drink resistance sound then, and output pin NO also exports positive voltage and promotes relay work.Relay can Control Engine stop working, or promotes radio paging system, also may command flash unit or the like.This device can repeatedly give a warning, and the noise of having avoided wrong report to produce has reduced user and neighbours' puzzlement, can also prevent that this equipment is destroyed, has characteristics such as easy to use, practical.

This device is when indoor application, if touched by the burglar, promptly can " please leave my house at once " with language is warned, if do not manage in 15 seconds, to turn off device, it also use rapid intonation " please leave my house at once " once more the warning, if do not turn off device yet in 30 seconds, it uses " everybody catches a thief " playback three times at once, and the high-decibel hummer sends the huge resistance sound of drinking then.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a circuit diagram of the present utility model.

Fig. 2 is another embodiment of the present utility model.
