Description

Redio set with burglar, theft or intruder alarm

The utility model relates to alarm technique, is a kind of device that burglar alarm and two kinds of functions of radio reception are united two into one, and belongs to the alarm class.

Along with Socialist Market Economy Development, the people who is a commercial traveler that out engages in trade gets more and more at present, and they often carry some cashes or commodity inhabitation hotel, in order to prevent the stolen of money and goods going along with.When sleep, burglar alarm is opened, often needed to listen to the radio programme the understanding economic information in the daytime again.

Therefore but the purpose of this utility model is a kind of device that burglar alarm and two kinds of functions of radio reception are combined of development to satisfy the needs that people not only can listen to information but also burglar alarm.

The technical scheme that realizes the utility model purpose is:

Burglar alarm radio reception two-purpose machine comprises common seven pipe radio part and burglar alarm parts, the shared loudspeakers of two parts (3), middle by a switch connection, it is characterized in that: burglar alarm partly comprises Fresnel Lenses (1), pyroelectric sensor (2), four high guaily unit integrated package (4), time base circuit (5), human infrared radiation is after Fresnel Lenses (1) focuses on, receive by pyroelectric sensor (2), convert electric signal to and trigger promotion loudspeaker (3) work after be transported to time base circuit (5) after the processing by four high guaily unit integrated package (4), the annexation of its circuit component is:

The D point that pyroelectric sensor (2) comes out connects C ₁, C ₂₃, R ₈, C ₁₀, R ₁₃, R ₁₅, IC ₆9, C ₁, C ₂₃Other end ground connection in parallel, the E point that pyroelectric sensor (2) comes out connects R ₂, C ₂, C ₄, C ₇, R ₁₁, BG ₃Emitter, C ₈Negative pole, IC ₅5, C ₉, IC ₆5, the end of loudspeaker SP, the S point that pyroelectric sensor (2) comes out connects R ₁₀And R ₂, C ₂The other end, R ₁The other end connects C ₃And IC ₁Positive pole, C ₃Another utmost point connects IC ₁Negative pole and R ₃, R ₃The other end connects R ₄, R ₅, C ₅, R ₄The other end connects C ₄Positive pole, R ₅Another termination C ₅Another utmost point and and IC ₁F point and C ₆Negative pole links to each other, C ₆The anodal R that connects ₆, R ₆The other end connects R ₇And IC ₂Positive pole, IC ₂Negative pole connects C ₇Anodal, R ₉, R ₁₀, R ₇The other end connect IC ₃Positive pole, IC ₂G point, IC ₄Negative pole, R ₈Another termination IC ₃Negative pole, R ₉The other end, R ₁₀Another termination IC ₄Anodal, R ₁₁The other end, IC ₃The H point connect BG ₁Positive pole, BG ₁Negative pole and R ₁₂And BG ₂Negative pole links to each other, BG ₂Positive pole meets IC ₄The K point, C ₁₀Minus earth, R ₁₂Another termination BG ₃Base stage, BG ₃Collector connects R ₁₄, R ₁₃The other end, R ₁₄Another termination IC ₅2, R ₁₅The other end connects C ₈Anodal, IC ₅6,7, C ₉Meet IC ₅1, IC ₅3 connect IC ₆1, IC ₆3 connect loudspeaker SP one end.

Fig. 1 is a principle of work block diagram of the present utility model, wherein: radio partly is that the normally used seven pipe radios in general market are formed, and (1) of burglar alarm part is that Fresnel Lenses, (2) are the LC1 of loudspeaker, (4) for pyroelectric sensor, (3) ... LC4 is that a LM324 four high guaily unit integrated package, (5) LC5 are time base circuit NE555.

Fig. 2 is circuit component wiring diagram of the present utility model, wherein Gear-shift switch S ₁Circuit is divided into top reports to the police partly and bottom radio reception part.

Now further narrate principle of the present utility model and structure by embodiment in conjunction with the accompanying drawings.

Embodiment: the utility model is made up of radio part and burglar alarm part, the shared loudspeaker of two parts, can fix on radio reception mode or burglar alarm mode to working method by a Gear-shift switch contact, partly be to act on the pyroelectric sensor (2) after the infrared radiation that sends according to human body focuses on by Fresnel Lenses (1) at burglar alarm, by it the infrared radiation signal of human body is transformed into electric signal, be input to then on the four high guaily unit integrated package of forming by four operational amplifiers (LM324), receiving time base circuit (5) LC5 then is on the NE555, triggers and reports to the police.

The utility model has the advantages that:

1, both can do radio reception and use receive fresh information, but burglar alarm again, a machine dual-purpose, easy to carry;

2, functional reliability is good, and is disguised strong, is difficult for being identified by stealer;

3, the unit cost is low, is convenient to promote the use of.
