Abstract

The utility model relates to a theft-proof alarm for yards, belonging to a theft-proof alarm device for the yards. The utility model is mainly composed of an antenna arranged on the front side of a sheet iron box, a printed circuit board arranged in the sheet iron box, integration blocks arranged on the printed circuit board and an alarm box (5) which is that a battery is arranged in a resistance and capacitance probe (2) and a buzzer, a light emitting diode and a switch are arranged on a resistance panel. The utility model has the advantages of simple structure and easy installation. The alarm of walk in 10 m is timely, and the dynamic state of committing a crime can be effectively pre-alarmed.

Description

Thief alarm in courtyard
The utility model belongs to the garden burglar alarm.
China generally adopts in vast rural area house not sharing an entrance with others inhabitation mode, night, antitheft problem never was well solved, and supported the special mode of protecting institute of dog even if adopt, and the robber still has the way that tackles, caused when night, people slept soundly, theft, assassination event happen occasionally.Safety case is not good enough.Still there is not reliable method and apparatus at present.
The purpose of this utility model provides a kind of burglar alarm that is exclusively used in rural area courtyard and the only institute of simple gate, to reducing the generation of theft, assassination event, maintains public order, and has important practical significance.
Figure of description 3 is electrical schematic diagrams of the present utility model, introduces structure of the present utility model and working condition according to Figure of description below.
A kind of garden burglar alarm of being made up of electronic component and circuit thereof, its circuit connection features are doppler effect sensors module I C 1(RD627) (1) (2) pin is T-Ring type antenna W ［ 1 ］ respectively, IC 1(3) (5) pin connect capacitor C respectively 1, IC 1(7) pin ground connection, and and capacitor C 2, resistance R 5, R 7The negative pole of hummer HA, light emitting diode VD 4Negative pole, power cathode link to each other IC 1(4) pin connecting resistance R respectively 4, R 6, controllable silicon VD 3Positive pole, resistance R 9, power switch K, IC 1(6) pin pass through resistance R 1Meet IC 2-1(LM324) (1) pin; IC 2-1(2) pin pass through resistance R 2Meet IC 2-1(3) pin, pass through R again 3Connect capacitor C respectively 2, integrated circuit (IC) 2-2(LM324) (2) pin, integrated circuit (IC) 2-3(LM324) (1) pin, IC 2-2(1) pin connecting resistance R respectively 6, R 7, IC 2-2(3) pin by diode VD 1, resistance R 8Meet controllable silicon VD 3The control utmost point; Integrated circuit (IC) 2-3(2) pin connecting resistance R respectively 4, R 5, IC 2-3(3) pin by diode VD 2, resistance R 8Meet controllable silicon VD 3The control utmost point; Controllable silicon VD 3Negative electrode connect the positive pole of hummer HA; Resistance R 9Sending and receiving optical diode VD 4Anodal.
When switch closes, by doppler effect sensors module I C 1The microwave signal that produces is radiated the space through its (1) (2) external tours antenna W of pin, and forming with the doppler sensor is the center of circle, with 10 meters be the three-dimensional police region of the semisphere territory of radius, this moment, circuit was in stand-by state, hummer is not reported to the police; When the robber walks about in alert army district, will be produced frequency displacement by the microwave signal of human body reflected back tours antenna and former transmitting, this frequency shift signal is through IC 1After inner detection was amplified, from (6) pin output ultra-low frequency signal, this signal was through R 1Deliver to by IC 2-1The amplifier of forming amplifies the back by IC 2-1(3) pin output, again through R 3Deliver to by operational amplifier IC 2-2, IC 2-3The window voltage comparator of forming, output HIGH voltage after relatively differentiating, this voltage is by diode VD 1, VD 2, current-limiting resistance R 8Trigger controllable silicon VD 3Conducting, buzzer warning, as long as probe is installed in the shelter of garden, reporting to the police is box-packedly got final product by the lead connection in indoor during use.
According to the described garden burglar alarm of above-mentioned situation, it is characterized in that by around with iron sheet only the front be plastic plate, have on the plate on the front plate of probe ［ 2 ］ that tours antenna ［ 1 ］ formed and box hummer hole ［ 3 ］ light emitting diode VD arranged 4［ 4 ］ and the warning box ［ 5 ］ of K switch ［ 6 ］ constitute.
According to the described garden burglar alarm of above-mentioned situation, the element arrangements on the wiring board on the base in it is characterized in that popping one's head in is that left end is a capacitor C 1［ 2 ］, sensor assembly IC 1［ 3 ］, resistance R 1［ 4 ］, right-hand member is controllable silicon VD 3［ 12 ］, resistance R 8［ 11 ］, diode VD 1［ 9 ］, VD 2［ 10 ］, the centre is an ic chip 2［ 6 ］, IC 2The left side is a resistance R 3［ 16 ］, R 2［ 15 ］ and capacitor C 2［ 5 ］, the right side is a resistance R 7［ 7 ］, R 6［ 8 ］, R 5［ 13 ］, R 4［ 14 ］.
