Abstract
The utility model discloses an acoustic control password anti -theft system, including pronunciation crypto module, digital crypto module and transmission module, the transmission module is connected respectively to pronunciation crypto module and digital crypto module, the pronunciation crypto module includes speech recognition chip and master control MCU, the digit crypto module includes keyboard and singlechip, the transmission module includes motor control unit and motor, the singlechip of digit crypto module and the master control MCU of pronunciation crypto module connect motor control unit respectively. The system is based on the processing and the recognition technology of voice signal, but the trick lock through recognition voice password and digital password can be based on the difference of the circumstances when opening the door, the different password of alternative use to the two all can independent control switch, can be by the extensive in all its aspects who is applied to life production.
Description
Technical field
The utility model relates to safe antitheft technical field, particularly a kind of acoustic control code anti-theft system that can be used on door, case etc.
Background technology
People, because leave behind key or key loss causes having to force open the door or prize case, bring numerous inconvenience to life.For the archiving district that security classification is high, traditional mechanical lock is also to meet security needs.Although a lot of speech cipher lock or digital cipher lock have appearred in market now, function singleness, has applied extensive not.
Utility model content
Technical problem to be solved in the utility model there is provided a kind of capable of speech password and numerical ciphers, by the acoustic control code anti-theft system that sound and numerical ciphers control or both independently control.
For solving the problems of the technologies described above, the utility model have employed a kind of acoustic control code anti-theft system, comprise speech cipher module, numerical ciphers module and transmission module, described speech cipher module and numerical ciphers module connection for transmission module respectively, described speech cipher module comprises voice recognition chip and main control MCU, described numerical ciphers module comprises keyboard and single-chip microcomputer, described transmission module comprises motor control unit and motor, and the single-chip microcomputer of described numerical ciphers module is connected motor control unit respectively with the main control MCU of speech cipher module.
Further, in the utility model, described voice recognition chip adopts LD3320 chip.
Further, in the utility model, described main control MCU adopts STC10L08XE single-chip microcomputer.
The beneficial effect that the utility model has: system based on the process of voice signal and recognition technology, by the coded lock of capable of speech password and numerical ciphers, the switch control rule of realizing circuit; Meanwhile, can according to the difference of situation when opening the door, the password that choice for use is different, and the two all can independent gauge tap, except can be used for archiving district, can also be widely used in the various aspects that life is produced.
Accompanying drawing explanation
Fig. 1 is system architecture diagram of the present utility model.
Embodiment
With reference to Fig. 1, for a kind of acoustic control code anti-theft system, comprise speech cipher module, numerical ciphers module and transmission module, described speech cipher module and numerical ciphers module connection for transmission module respectively, described speech cipher module comprises voice recognition chip and main control MCU, described numerical ciphers module comprises keyboard and single-chip microcomputer, and described transmission module comprises motor control unit and motor, and the single-chip microcomputer of described numerical ciphers module is connected motor control unit respectively with the main control MCU of speech cipher module.
Acoustic control code anti-theft system described in the utility model primarily of speech cipher module, numerical ciphers module, single-chip microcomputer and transmission module etc. four part composition, system global structure figure as shown in Figure 1, wherein speech cipher module, adopts with the LD3320 chip speech recognition evaluation board that is core to realize the recognition function of speech cipher.If speech cipher input is correct, then by single-chip microcomputer, instruction is sent to control system, realize controlling the enabling of this password door by kinematic train.Numerical ciphers module is then the keyboard password lock adopting matrix nonencoded keyboard and be designed to, and after input numerical ciphers, single-chip microcomputer is by this password and arrange password and compare, by transmission module again opposite house carry out corresponding operation.
Described speech cipher module adopts LD3320 voice recognition chip, LD3320 inside is integrated with the optimized algorithm of fast and stable, therefore the memory devices such as external Flash and RAM are not needed, user is not needed to realize training and the speech recognition of unspecified person of recording with LD3320 yet, therefore the phonetic recognization rate of LD3320 is more stable, and accuracy rate is also higher.The hardware circuit of speech cipher module is primarily of control panel and M-LD3320 module composition, and M-LD3320 is used for speech recognition, and that main control MCU adopts is single-chip microcomputer STC10L08XE.Software program is all stored in the built-in Flash of MCU, and main control MCU directly control M-LD3320 module completes all work relevant with speech recognition.
Described numerical ciphers module with STC89C51 single-chip microcomputer for core control part, in conjunction with key scanning circuit, LCD digital pipe display circuit, monolithic processor resetting and crystal oscillating circuit, utilize single-chip microcomputer Programming and abundant I/O port flexibly, and the accuracy controlled controls by software program the basic function that whole system realizes electronic password lock.
Described input through keyboard module is divided into Password Input button and several function button, for completing coded lock input function; Described buzzer alarm circuit is for completing alarm function when inputing password by mistake; Described crystal oscillating circuit is used for the starting of oscillation of single-chip microcomputer; Described reset circuit is used for the reset of completion system; Described LCD display module has been used for system state display and operation indicating function.
Described transmission module module core parts are 51 monolithic processor controlled motors, when correct by the voice of voice or input through keyboard, by transmission module, door are opened; Described transmission module is connected with sound identification module and keyboard password module, utilizes the master slave communication mode in multi-computer communication, the information that two crypto modules send is processed, thus complete the switching manipulation of opposite house.
System adopts 2 LED light to carry out input instruction, it is correct that one of them lamp is used to indicate speech cipher, and it is correct that another lamp is used to indicate keyboard password keyboard, when voice and keyboard password all input correct, by two bright displays of pilot lamp, door just can be opened.
