Abstract
The invention discloses a voice door lock system of an antitheft door. The voice door lock system includes a voice chip recognizing voice input and controlling voice output, a DSP module, a programmable logic device, a random access memory, a flash memory module, a status indicating lamp and a DIP button. A voice data acquisition module converts an analogue voice signal into a digital signal. Data process mainly includes extraction of parameters of the voice of a speaker. A memory module includes two parts: the SDRAM part and the FLASH part, wherein the SDRAM is used for storing data during DSP processing and the FLASH is used for storing program codes and a template library of training. By means of CPLD, the DIP button, a liquid crystal display and a status indicator lamp can be controlled, wherein the DIP button sends a control command motion (recognition, training and template erasing) to the DSP board. An operation status and a recognition result of a program can be displayed on the liquid crystal display.
Description
Technical field
The present invention relates to a kind of door-locking system, particularly a kind of voice door lock system of antitheft door.
Background technology
In today of information networking and economic globalization, the problems such as traditional identity identifying method carrying inconvenience as used I.D., key, smart card, password etc. to exist, easily losing, being forged, password is easily cracked, its security is low, poor reliability.And based on the authentication of biological characteristic compared with conventional authentication mode, there is the advantage such as uniqueness, unchangeability, not easily imitation, become many countries and paid much attention to and the gordian technique greatly developed.In biometrics identification technology field, Speaker Identification (Speaker Recognition) is subject to people with advantages such as the convenience of its uniqueness, economy and accuracys and more and more pays close attention to.
Summary of the invention
The object of the invention is the voice door lock system designing a kind of antitheft door, speaker Recognition Technology is applied on the door lock of antitheft door, substantially increase the security performance of antitheft door.
For achieving the above object, the technical solution used in the present invention is:
A voice door lock system for antitheft door, it comprises: sound chip identification phonetic entry and control voice output, DSP module, programmable logic device (PLD), random access memory, flash memory module, status indicator lamp, DIP button.Audio data collecting module.It is characterized in that: audio data collecting module completes and converts simulated audio signal to digital signal.Data processing mainly completes the extraction to speaker's speech parameter.Storer is used for storing the template base of data in DSP processing procedure, program code and training.Utilize CPLD can control DIP button, liquid crystal display (LCD) and status indicator lamp (LHI).Wherein DIP button can send control command action (identify, train and template erasing) to dsp board, and the running status of program and recognition result can be presented on LCD.
Above-mentioned audio data collecting module is completed by audio coding decoding chip, completes the configuration to its internal register by I2C control circuit.I2C bus is the universal serial bus be made up of data line SDA and clock SCL, can transmit and receive data.
The present invention has following Advantageous Effects:
Antitheft door voice door lock system of the present invention is exactly one of application of speaker Recognition Technology, when voice door lock starts to identify, first the voice signal collected specifically is processed, then pattern match is carried out to the proper vector in template base, then export recognition result and determine whether unblanking.Fundamentally can solve the safety problem of antitheft door, and bring many convenience to household.
Accompanying drawing explanation
Fig. 1 is present system hardware structure diagram.
Fig. 2 is I2C inside modules figure.
Embodiment
This invention is set forth further below in conjunction with accompanying drawing.
In FIG, a kind of voice door lock system of antitheft door, it comprises: sound chip is known the other phonetic entry of module 1 and controlled voice output, DSP module 2, programmable logic device (PLD) 3, random access memory 4, flash memory module 5, status indicator lamp 6, DIP button 7, LCD MODULE 8.It is characterized in that: when voice door lock starts to identify, by audio data collecting module acquires voice messaging, send sound chip 1 to specifically to process, complete and convert simulated audio signal to digital signal, the extraction to speaker's speech parameter is completed again by the data processor of DSP module 2, and parameter is stored into flash memory module 5, programmable logic device module 3 is extracted the parameter that stored and the proper vector in itself and template base is carried out pattern match from flash memory 5, if parameter is consistent, then status indicator lamp 6 shows green, DIP button 7 comes into force, then the running status of program and recognition result can be presented in LCD module 8.
Described audio data collecting module 1 is completed by audio coding decoding chip, completes the configuration to its internal register by I2C control circuit.
In fig. 2, data transmitter register ICDXR, send shift register ICXSR, receive shift register ICRSR and data receive register I (3) RR be responsible for transmission and the reception of serial data on SDA; Clock synchronizer, the clock be used on synchronous I2C input clock (from DSP clock generator) and SCL pin, also wants the data transmission of synchronous different frequency main equipment; The principle that arbitration unit detects according to competition, all data of I2C module are all connected with DSP by 16 inner peripheral bus.
Claims (4)
