The utility model has the advantages of small volume, simple circuit, multifunction, portability and low cost and is a popular personal alarming device for the outgoing people.
Description
A kind of Small alarm, it belongs to small alarming device.
Existing warning system product category is various, though the small-sized thing alarm of taking also once had, volume is bigger, and the components and parts of usefulness are more, and purposes is single, carries very inconveniently, and price is more expensive.The Small alarm that certain is external, the physical dimension of transmitter are 105 * 40 * 17mm, and the physical dimension of receiver is 88 * 62 * 20mm, wherein adopt three of integrated packages, three of transistors, five of diodes, three of telefaults, one in transformer, one of piezoelectric patches, one of luminous indicating lamp, two on switch, 18 in capacitor, 16 of resistance, No.5 cell five joints.
The purpose of this utility model is, develops a kind of small-sized Small alarm, and it is little that it should have a volume, and circuit is simple, function is many, and is easy to carry, lower-price characteristic, and this device is made up of transmitter and receiver two parts, the use of working in coordination, and answer reliable operation, response is sensitive.
Technical solution of the present utility model is: a kind of Small alarm, it is made up of a transmitter and a receiver, the signal that transmitter sends is received machine and receives, both work of working in coordination, special character of the present utility model is, transmitter is made up of pulse oscillator, high frequency oscillator, power supply and emitting antenna, and receiver is made up of receiving antenna, superregenrative reception, detuner, power supply Homeway.com Chinese percussion instrument.
Emitting antenna and receiving antenna adopt the loop configuration that is printed on the circuit board.
The detuner of receiver only adopts an integrated package.
The profile of transmitter housing is a password bag shape, and is provided with the bag handle that can be used to take the extension object, and a side is equipped with a micro lighting lamp.
The housing of receiver is provided with the hook that hangs on the waistband.
The guiding theory of above-mentioned technical solution is: the work of working in coordination of the transmitter and receiver of Small alarm, when the transmitter energized, pulse oscillator produces pulse signal, and this signal is modulated the high frequency constant-amplitude signal after entering high frequency oscillator, is launched by antenna then.When the receiver energized, antenna is received high-frequency signal through ovennodulation behind superregenrative reception and detuner, output be low level, the sound does not take place in the news Chinese percussion instrument.Just in case the transmitter distance receiver is about more than 10 meters when far away, because receiver can not receive the signal that the antenna of transmitter sends, the detuner of receiver will be exported high level, and the news Chinese percussion instrument sends the sound, the beginning of promptly reporting to the police, and reminds people notes meeting accident thing.If transmitter-off, alarm sound can take place in receiver immediately.As seen, if when going on business, transmitter is placed in the bag, or when going out, transmitter is placed on one's body the child, walk when far away packet loss or child, the receiver of carrying will be reported to the police to you immediately.
Effect of the present utility model is, by a transmitter and the Small alarm that receiver is formed, owing on circuit, profile, structure, all carried out bigger improvement, the components and parts that this device is adopted are less, thereby simplified circuit, reduced volume, the physical dimension of existing apparatus transmitter is 50 * 58 * 17mm, the physical dimension of receiver is 56 * 76 * 17mm, and therefore, manufacturing cost reduces.Transmitter has takes the function of hanging key and night illumination.When transmitter-off; or the transmitter distance receiver is about more than 10 meters when far away, and receiver can send audible alarm immediately, and reliable operation, response sensitivity; so be to go out to protect valuables, the indispensable small alarming device of carrying such as prevent that child wanders away.
Description of drawings:
Accompanying drawing 1 is a kind of ultimate principle block diagram of Small alarm;
