Embodiment Construction

[0033] Next, the method and device for directly starting a car and preventing theft by voice based on an embedded system of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] The method for directly starting the car and anti-theft based on the voice of the embedded system, the steps are:

[0035] 1), the central control unit sends the voice prompt command to the voice prompt unit, and the voice prompt unit plays the prompt voice through the speaker after receiving the command;

[0036] 2) After the user hears the prompt voice, he speaks the voice command that was originally entered. The voice acquisition unit converts the voice command into an analog electrical signal and sends it to the voice codec. to the central control unit;

[0037] 3), the central control unit calculates and processes the input voice digital signal, and compares and recognizes it with the voice model in the storage unit;

[0038]4) After the id...

Abstract

The invention discloses a method and a device for directly starting an automobile by voice and preventing thievery on the basis of an embedded system. The method includes that a voice prompting command is transmitted from a central control unit to a voice prompting unit, and prompting voice is played via a loudspeaker after the voice prompting unit receives the command; a user says a voice command recorded in advance after hearing the prompting voice, a voice acquisition unit converts the voice command into analog electric signals and transmits the analog electric signal to a voice codec, and the voice codec samples and encodes the analog electric signals, then converts the analog electric signals into digital signals and transmits the digital signals to the central control unit; the central control unit computes the inputted voice digital signals, compares the voice digital signals with a voice model in a storage unit and identifies the voice digital signals; and an automobile starting command is transmitted to an automobile starting control unit after the voice digital signals are identified, and the automobile is started after the automobile starting unit receives the automobile starting command. A thievery prevention function of the automobile is realized according to uniqueness of acoustic features of the voice, identity of the speaker is analyzed and identified by mode recognition technology, and whether to directly start the automobile or not is judged.

Description

technical field [0001] The invention relates to the starting and anti-theft of automobiles, in particular to a method and device for directly starting the automobile and anti-theft based on the voice of an embedded system. Background technique [0002] Embedded system is application-centric, based on computer technology, software and hardware can be tailored, suitable for application systems, special-purpose computer systems that have strict requirements on function, reliability, cost, volume, and power consumption. It has the advantages of small size, strong specificity, high reliability, strong real-time performance, fast execution speed, and good scalability. It generally consists of microprocessors (MPUs) or microcontrollers (MCUs), peripheral hardware devices, embedded operating systems, and specific application programs. Pattern recognition can be better realized by using embedded system. [0003] Pattern recognition technology is the basic technology of artificial i...
