Abstract

The invention discloses a combination lock with a voice recognition function, comprising a first singlechip, a manual cipher input device, an LED (Light Emitting Diode) liquid crystal display screen, a controlled electronic lock body and a driver, wherein the driver is connected with the first singlechip for driving the controlled electronic lock body. The combination lock is characterized by also comprising a second singlechip, wherein the second singlechip is connected with a microphone used for inputting voice information; the output end of the second singlechip is connected with a loudspeaker; and the second singlechip and the first singlechip are subjected to communicating junction by a serial port protocol. In the combination lock, a voice cipher and manually input cipher are combined to improve system safety.

Description

Coded lock with speech identifying function

Technical field

The present invention relates to a kind of coded lock.

Background technology

At present, known lock is by pure frame for movement or common keyboard password control.For mechanical lock, the person of unblanking all heads into all pellets shot from a slingshot, topmost with key or special tool(s), by means of torsion; By means of the terrace between the inside and outside lock core marble hole; Under the effect of spring force, pellet shot from a slingshot falling, outer pellet shot from a slingshot hinder outside internal cylinder in making, thereby open lock.Some lawless persons can carry out according to specific frame for movement and unblank, and form theft easily.For the keyboard password lock, some lawless persons can utilize programming, with password cracking, thereby also form theft easily.

Summary of the invention

In order to overcome the shortcoming that above-mentioned prior art exists; The object of the present invention is to provide a kind of coded lock with speech identifying function; It combines speech cipher with manual input password, can not only improve the safety of system, and speech cipher and touch-screen have embodied the hommization of system.

In order to address the above problem; The present invention adopts following technical scheme: the coded lock that this has speech identifying function comprises first single-chip microcomputer, password manual input device, LCD LCDs, controlled electronic lock body and is connected the driver that is used to drive controlled electronic lock body with first single-chip microcomputer; Also comprise second singlechip, connection one is used to import the microphone of voice messaging on the second singlechip; The output of second singlechip connects a loudspeaker; Said second singlechip is connected through the serial port protocol communication with first single-chip microcomputer.

As further technical scheme of the present invention:

Have in the coded lock of speech identifying function at this, said password manual input device is touch-screen/keyboard.

The invention has the beneficial effects as follows: it combines speech cipher with manual input password, can not only improve the safety of system, and speech cipher and touch-screen have embodied the hommization of system.Can be widely used in the entrance guard management in confidential places such as the weapons storehouse of automobile, army or public security department, the storehouse of depositing explosive, archive.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is done further explanation:

Fig. 1 is the circuit principle structure figure of the embodiment of the invention.

The specific embodiment

Coded lock as shown in Figure 1, that this has speech identifying function comprises first single-chip microcomputer, second singlechip; First single-chip microcomputer is selected the C8051F020 single-chip microcomputer for use, and second singlechip is selected the SPCE061A single-chip microcomputer for use.

This coded lock with speech identifying function also comprises controlled electronic lock body and is connected the driver that is used to drive controlled electronic lock body with the C8051F020 single-chip microcomputer.Connect password manual input device, LCD LCDs, DS1302 clock on the C8051F020 single-chip microcomputer.This password manual input device is touch-screen/keyboard.

Connection one is used to import the microphone of voice messaging on the SPCE061A single-chip microcomputer; The output of second singlechip connects a loudspeaker.

Said SPCE061A single-chip microcomputer is connected through the communication of RS232 serial port protocol with the C8051F020 single-chip microcomputer.

Its principle is following:

Before the use; Earlier the SPCE061A single-chip microcomputer is instructed sound; Promptly the sound that is allowed to unlocking person is got into the SPCE061A single-chip microcomputer through microphone, speaker's personal characteristics parameter is stored, machine forms the speaker characteristic parameter database in the SPCE061A single-chip microcomputer.

When identification, voice to be identified and speaker characteristic parameter database are mated, accomplish speech recognition.After the speech recognition success; SPCE061A single-chip microcomputer and c8051f020 single-chip microcomputer are set up communication protocol through the RS232 serial ports; The LCD LCDs can show printed words, for example " asks the input keyboard password ", and the prompting speaker passes through touch-screen/keyboard input keyboard password for example " 123456 ".After voice and keyboard password were all discerned success, c8051f020 Single-chip Controlling driver acted on controlled electronic lock body, realizes unblanking.Simultaneously, the LCD LCDs shows date, the time, and this function is realized by the DS1302 clock.

The SPCE061A single-chip microcomputer has 10 D/A converters of binary channels of audio output function, can accomplish the voice suggestion of various operations such as user's training, identification.The audio frequency way of output that SPCE061A provides is a binary channels DAC mode; Under this mode; The analog quantity current signal of DAC1 and DAC2 conversion output is exported with the AUD2 pin through AUD1 respectively, and the word amount of input writes P-DAC1 (writing) respectively (0x7017) and (0x7016) unit of P-DAC2 (writing).Touch-screen/key input section has 16 buttons such as numerical key, password setting key, password display key, acknowledgement key and clearing password key, is used for the realization of password input and function button.

Claims

1. the coded lock that has speech identifying function comprises first single-chip microcomputer, password manual input device, LCD LCDs, controlled electronic lock body and is connected the driver that is used to drive controlled electronic lock body with first single-chip microcomputer; It is characterized in that: also comprise second singlechip, connection one is used to import the microphone of voice messaging on the second singlechip; The output of second singlechip connects a loudspeaker; Said second singlechip is connected through the serial port protocol communication with first single-chip microcomputer.

2. the coded lock with speech identifying function according to claim 1 is characterized in that: said password manual input device is touch-screen/keyboard.
