Abstract
A music car locator comprises a main control chip, an alarm circuit and a wireless receiver are connected with the main control chip, a wireless transmitter is matched with the wireless receiver, the alarm circuit is connected with an MP3 (moving picture experts group audio layer-3) decoder via a signal detecting circuit, and the MP3 decoder is connected with a horn. The MP3 decoder comprises an MP3 decoding chip, and the MP3 decoding chip is connected with a digital amplifier chip and transmits a decoded and amplified signal to the horn. By adding an MP3 music playing function on an original alarm device of a car, original alarming voice is changed into MP3 music, so that unique and individual alarming voice can be owned by each car, misjudging of other car owners is avoided, a user can change an SD card or a music file in a USB (universal serial bus) disk can be changed according to personal favors, and the music car locator is strong in pertinence and capable of realizing fast exclusive location of the car.
Description
Technical field
The present invention relates to a kind of car finding device, be specifically related to a kind of by the music car finding device of different music with vehicle location.
Background technology
Car more and more becomes the main vehicles of people.Yet the people of fast pace life often forget the accurate position that own vehicle is parked when stopping.When car is sought in the parking lot, only be difficult to find the vehicle of oneself sometimes with the normal remote control in the hand, particularly in the peak period of picking up the car, the akin tweeting sound that rises one after another is difficult to tell the particular location that oneself vehicle is parked.In addition, no matter we are the rests of being in, or the work hours, and car is all concentrated relatively and parked, in case when hearing the car alarm call, whether a lot of drivers can worry is oneself vehicle is damaged, and makes troubles to the car owner.
Summary of the invention
At the deficiencies in the prior art, the purpose of this invention is to provide a kind of music vehicle tracking device that can accurately judge own vehicle location.
The object of the present invention is achieved like this: a kind of music vehicle tracking device, comprise a main control chip, warning circuit, wireless receiver are connected with the main control chip, radio transmitters and wireless receiver coupling, warning circuit connects by signal deteching circuit MP3 decoding device, and the MP3 decoding device is connected with loudspeaker.
Described MP3 decoding device comprises a MP3 decoding chip, and the MP3 decoding chip is connected with the digital power amplifier chip, and the signal after decoding and the amplification is passed to loudspeaker.
The MP3 decoding chip links to each other with the exterior storage interface.
The MP3 decoding chip is ATS2300.The digital power amplifier chip is PAM 8610 digital power amplifier chips.
Described exterior storage interface is SD clamping mouth or USB interface.
The invention provides the music vehicle tracking device, increase broadcast MP3 music function by the warning device at former car, original alarm sound is replaced with the MP3 music, make every vehicle that unique alarm sound all can be arranged, can not cause erroneous judgement, and the user can change music file in SD card or the USB flash disk according to the personal preference, and is with strong points, the quick location that can realize vehicle.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the former figure block diagram of circuit of the present invention.
Fig. 2 is MP3 decoding device theory diagram of the present invention.
Fig. 3 is testing circuit figure of the present invention.
CON1 connects warning circuit among Fig. 3, and CON2 connects the MP3 decoding device.
Embodiment
Structure of the present invention is referring to Fig. 1-3: a kind of music vehicle tracking device, involving vibrations sensor 10, infrared sensor 11, vibration transducer 10, infrared sensor 11 all is connected with main control chip 1, and warning circuit 2, wireless receiver 3 are connected with main control chip 1, radio transmitters 4 and wireless receiver 3 couplings, warning circuit 2 is connected with MP3 decoding device 5 by signal deteching circuit 6, and MP3 decoding device 5 is connected with loudspeaker 12.Described MP3 decoding device 5 comprises a MP3 decoding chip 7, and MP3 decoding chip 7 is connected with digital power amplifier chip 8, and the signal after decoding and the amplification is passed to loudspeaker 12.
Principle of work of the present invention is as follows:
During warning, experience body vibrations by vibration transducer 10, infrared sensor 11 is experienced the stranger and is entered, and signal all sends MCU main control chip 1 to after amplifying; Finishing car door by main control chip 1 control car door electromagnet 13 opens and closes;
When seeking car, the car owner sends order by radio transmitters 4, after wireless receiver 3 receives the signal of radio transmitters 4, sends MCU main control chip 1 to;
After main control chip 1 receives signal, by the relay adhesive, make MP3 decoding device 5 work, play and deposit the SD card that links to each other with outside storage interface 9 or the mp3 file in the USB flash disk, through digital power amplifier chip 8 go into after, exported by loudspeaker 12.The present invention only needs the wiring of former car (warning) loudspeaker is extracted when making, and inserts the MP3 module, single alarm sound can be changed into personalized MP3 music.
The course of work of signal deteching circuit 5 is as follows:
Pulse 2.28S wave period of long sound, about 1.8S of the time of high level, low level time 0.5S, short sound is 2 short period waveforms in the time of end, cycle 0.2S, high level and low level be each 100ms approximately.
According to the following testing circuit of Waveform Design: after resistance R 1 current limliting, connect the triode ground level during former car audible warning high level, triode Q1 conducting, relay R ELAY adhesive is powered to MP3, and former car audible warning input just is full of capacitor C 1 in a flash.
When former car loudspeaker no signal, capacitor C 1 storage is that electric weight passes through resistance R 1 discharge, makes triode Q1 conducting, and the relay adhesive is powered to MP3, about 8 seconds of the duration (can determine delay time as required).
When long the warning, about 13 seconds of former car audible warning T.T., add 8 seconds of time-delay, and MP3 prepares to need 3 seconds, and music is 18 seconds (13+8-3=18), and low level time is very short in the signal of 13 second time of loudspeaker, much smaller than time-delay 8 seconds, can not interrupt MP3 and play.
When lock and unlock, 1 second loudspeaker output signal duration, delayed time music 6 seconds 8 seconds.
The MP3 decoding device: the MP3 decoding device is by ATS2300 MP3 decoding chip, and PAM 8610 digital power amplifier chips adopt the 12V power supply, and band 15W power amplifier is supported SD card and USB flash disk, powers on and plays music file in SD or the USB flash disk automatically.
