Abstract
The utility model relates to a theft-proof alarm for a motorcycle, which is provided with a vibration type sensor, an impedance conversion circuit, an amplification driving circuit, a photo-electrically coupled integrated block IC1, a language integrated block IC2, a power amplifier IC3 and a loudspeaker. The utility model can detect motorcycle-theft signals through the vibration type sensor, and the motorcycle-theft signals can be converted into sound signals through the language integrated block IC2 to send out alarm. The utility model has the advantages of simple structure, convenient installation, convenient operation and safety use.
Description
The relevant a kind of motorcycle anti-theft warning device of the utility model.
Existing distance type motor annunciator line construction complexity, install loaded down with trivial detailsly, performance is understable, and does not have linguistic function, and remote controller need carry at one's side for a long time, enters or removes warning and all need button, troublesome poeration.
The purpose of this utility model is to overcome the defective of prior art, provide a kind of line construction simple, have linguistic function, installation and a motorcycle anti-theft warning device easy and simple to handle.
The utility model is provided with a vibration-type inductor, impedance inverter circuit, amplification driving circuit, photoelectricity coupling ic chip 1, language integrated package IC2, amplifirer IC3 and loudspeaker, impedance inverter circuit adopts field effect transistor BG1, its trigger end connection inductor, mouth is through the input end of amplification driving circuit connection photoelectricity coupling ic chip 1, two output pins of photoelectricity coupling ic chip 1 connect two input ends of language integrated package IC2 respectively, the output pin of language integrated package IC2 connects the input end of amplifirer IC3, loudspeaker are connected in the output of amplifirer IC3, the working power of above-mentioned each components and parts provides by the motor bike storage battery, and is provided with source switch K.
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Accompanying drawing is the line assumption diagram of present embodiment.
Present embodiment is provided with vibration-type inductor 1, impedance inverter circuit, amplification driving circuit, photoelectricity coupling ic chip 1, language integrated package IC2, amplifirer IC3 and loudspeaker, impedance inverter circuit adopts field effect transistor BG1, its trigger end connection inductor 1, mouth is through the input end 2 of amplification driving circuit connection photoelectricity coupling ic chip 1, the output pin 3 of photoelectricity coupling ic chip 1,4 connect the input end 5 of language integrated package IC2 respectively, 2, the output pin 4 of language integrated package IC2 connects the input end of amplifirer IC3, loudspeaker are connected in the output of amplifirer IC3, the working power of above-mentioned each components and parts provides by the motor bike storage battery, and be provided with source switch K, above-mentioned amplification driving circuit is by aerotron BG2, the second amplifying circuit that BG3 forms, K switch can be replaced by motor bike storage battery lock in this example, when opening motor bike storage battery lock, K switch is cut off (interlock), remove alarm condition, otherwise, be on the alert.
After present embodiment is installed and used, in case there is the people to steal car, the generation vehicle rocks, vibration-type tablet 1 produces an impulse singla, trigger field effect transistor BG1 and become electric signal by BG1, this electric signal is through aerotron BG2, the amplification driving circuit direct drive photoelectricity coupling ic chip 1 that BG3 forms, be coupled by 5 through the IC1 interior lights, the output of 4 pin, pass to language integrated package IC2, IC2 is triggered owing to obtaining a pulse electrical signal, from 4 pin output language signals, speech signal through the enough speech frequency speech signals of amplifirer IC3 processing and amplifying output, converts aud. snl. by loudspeaker through capacitive coupling.
The utility model makes that owing to having adopted vibration-type inductor and language integrated package to report to the police as detection of stealing the car signal and transmission this apparatus structure is simple, and is easy for installation, easy and simple to handle, uses more safe and reliable.
