Specific implementation
With reference to Fig. 1, a kind of voice recognition automotive theft proof system comprises sound collection unit, control unit, performance element and voice alerting unit, and sound collection unit, control unit, performance element link to each other successively, and control unit also links to each other with voice alerting unit; Described sound collection unit adopts acoustic pickup, is used to gather the sound that chaufeur sends, and sends the sound that it collects to control unit; Described control unit comprises computing machine, micro controller system and amplifying circuit, be used for the sound of chaufeur is analyzed by the sound that calculator memory stores up, then the legal signal after the comparative analysis is passed to micro controller system, at last the signal after the processing of micro controller system is passed to performance element by amplifying circuit; Described performance element adopts relay, and links to each other with amplifying circuit in the control unit; Described voice alerting unit is a loudspeaker device, gives the output signal of control unit extraneous by voice delivery.When aud. snl. comparison nonconformity, send " Fei Benche driver, refusal starts " and carry out voice suggestion.Compare when qualified when aud. snl., send " please start vehicle " and carry out voice suggestion.The electric power system of this device is provided by automobile batteries, and voltage is 12V.
With reference to Fig. 2, the automotive theft proof system of voice recognition of the present utility model obtains the sound of chaufeur by acoustic pickup, send to behind the computing machine and the sound of its storage inside is analyzed, if signal is illegal, after the voice sound equipment received the signal of "No", the voice sound equipment sent the suggestion voice of refusal vehicle launch.If signal is legal, after then the voice sound equipment received the signal of "Yes", the voice sound equipment sent the suggestion voice that starts vehicle.Simultaneously legal signal is sent to micro controller system, the control signal of micro controller system output control relay closure after amplifying circuit amplifies realizes the conducting of ignition circuit.
With reference to Fig. 3, because the power supply that the utility model uses is an automobile batteries, could supply micro controller system work so will drop to 5V to the voltage of 12V, the utility model adopts 7805 stabilivolts to reach the effect of step-down, realizes the conversion of voltage.The filter capacitor of noting respectively connecting on the input and output pin when using 7805 reaches the heat-dissipation purpose.Micro controller system of the present utility model adopts STC11F02, and this micro controller system is the 5V micro controller system, can realize the closure of relay by programming.Because the output signal of micro controller system is strong inadequately, can not drive the relay contacts closure, therefore adopts the ULN2003 enlarging function that control signal is amplified and drove relay afterwards.
