The design Sunplus Technology, Inc., SPR4096 as a memory expansion, bined with SPCE061A broadcast voice. SPR4096 in use, the use of SPR4096 Rewriter to read and write operation, used to store the speaker39。s personality parameters reference template.SCM SPCE061A plete identification and display, the drive to realize the implementation of the electromagnetic lock function, and to detect its drive current value, to receive alarm signals sent by sensors, such as sending data. SCM receive the type code, and stored in FLASH in the password, if the correct password, the drive for the implementation of the electromagnetic lock, if your password is not correct, allowing operators to reenter your password, can enter up to three If the three are not correct, the MCU through intelligent munication lines to monitor the police. SCM will unlock operation and each time the electromagnetic actuator drive current value as a status information sent to the smart monitor, will receive the report from the sensor interface information is also sent to the intelligent monitoring, as smart Analysis of the basis. In the transmitter, electronic locks through the pulse transformer T will modulation good boost after data signals sent out in the receiver, pulse transformer T will receive the data signal demodulator buck evacuation to reduce the carrier signal transmission In the process of wear and tear. In order to reduce munication and mutual interference between the power supply, chokes L, the choice of coupling capacitance C to prehensive considerations, shown in Figure 4, a carrier frequency f0400kHz, in order to ensure that most of the energy transmission signal to the receiver Duan, L for a H, ~ surveillance function is to prevent the destruction of munication lines and electromagnetic actuator, for some reason the flow of electromagnetic coil currents too large burning coil. Current Monitor by MAXIM pany39。s current / voltage converter chip MAX471. The chip can be measured current I into pairs to the output voltage U, and is measured Wai, high precision, and U output voltage proportional to the measured current I characteristics. Current monitor output voltage service A / D converter, read through the single A / D converter results in the current line was informed of the situation, through the timely detection of abnormal, issued its report.SPCE061A the developments of online debugger PROBE To achieve. It uses a builtin online SPCE061 Circuit Simulation ICE (InCircuit Emulator) and Sunplus39。s online series Line programming. PROBE can work in Sunplus IDE Integrated Development Environmental software NSP (tm), with editing, pile, and link, debug and simulation capabilities. Use IDE friendly interface, the dropdown menu, shortcuts and quick access to the list can be ordered so that the user39。s programming and missioning work more convenient and efficient. In addition, IDE software simulation can not connect the simulation board under the simulated conditions of the various functions to the hardware debugger. When the system work, the main function of the call to plete a specific function of the human voice training, training for the future success of voice recognition, according to the order to identify the implementation of the keyboard control operation, according to the different function keys, the implementation of the corresponding procedures, to plete Password changes settings, contrast, shows, and other functions.The system uses a SPCE061A 16bit microcontrollers embedded voice processing and control system, easy to use, easy to use, but the speech recognition capabilities have yet to be improved. Electronic password lock technology development so far, has been widely used in higher property security areas as information technology and puter technology and the constant development, voice, electronic password lock technology will have greater development and, ultimately, achieving efficiency, safety and reliable Voiceprint control of the voice of electronic locks.外文文獻的譯文語音電子密碼鎖的設計本課題是采用語音識別技術加鍵盤控制輸入，在凌陽SPCE061A單片機上實現(xiàn)的一種語音電子密碼鎖認證系統(tǒng)。語音識別并配合電子密碼鎖的普通鎖具功能，實現(xiàn)雙重安全保障作用。該密碼鎖安全、有效、可靠，而且具有語音識別、密碼預置、保密性強誤碼提示等特點。 隨著人們生活水平的提高和安全意識的加強，鎖具系統(tǒng)的安全性變得至關重要，于是出現(xiàn)了密碼鎖磁性鎖、電子鎖、激光鎖、聲控鎖等鎖具，它們是在傳統(tǒng)鑰匙的基礎上，利用一或多組密碼，不同聲音不同磁場，不同聲波，不同光束光波，不同圖像(如指紋、眼底視網(wǎng)膜等)等來控制鎖的開啟。本文采用語音識別技術和鍵盤控制輸入相結合，在凌陽SPCE061A單片機上實現(xiàn)一種語音電子密碼鎖認證系統(tǒng)。系統(tǒng)主要由凌陽SPCE061A單片機、MIC輸入電路、語音輸出電路、44鍵盤、6位七段LED顯示、輸出控制及FLASH存儲器組成。系統(tǒng)主要的功能是：在訓練時，說話人的聲音通過麥克風進入說話人語音信號采集前端電路，由語音信號處理電路對采集的語音信號進行特征化和語音處理，提取說話人的個性特征參數(shù)并進行存儲，形成說話人特征參數(shù)數(shù)據(jù)庫。在識別時，將待識別語音與說話人特征參數(shù)數(shù)據(jù)庫進行匹配，完成語音識別以及鍵盤的控制，實現(xiàn)激活或解除鎖具，最終完成開鎖。系統(tǒng)是依靠硬件和軟件地密切配合，由凌陽SPCE061A單片機的靈活控制實現(xiàn)的。語音輸入由于受到外部環(huán)境的干擾，有可能出現(xiàn)錯誤，但通過多次的訓練可以使語音對比和識別有很大的提高。系統(tǒng)采用具有內(nèi)核的凌陽SPCE061A單片機，該芯片內(nèi)有ADC、DAC、定時器／計數(shù)器、RAM、FLASH等器件，加上適當?shù)耐鈬娐放c配套的凌陽公司的集成開發(fā)環(huán)境，可以很方便地完成硬件設計和軟件編程，從而實現(xiàn)上述功能。語音電子密碼鎖系統(tǒng)的核心是說話人識別模塊。SPCE061A是凌陽公司開發(fā)的一種性價比非常高的16位單片機，內(nèi)嵌2K字的SRAM和32K字的FLASH，具有32位可編程的多功能I／O端口；包含有7通道1O位通用A／D轉(zhuǎn)換器、內(nèi)置麥克風放大器、自動增益控制AGC功能的單通道聲音A／D轉(zhuǎn)換器，以及具有音頻輸出功能的雙通道1O位D／A轉(zhuǎn)換器；在2．6V~3．6V工作電壓范圍內(nèi)，工作頻率范圍為0．32MHz~49．152Mhz，較高的處理速度使其能夠非常容易、快速地處理復雜的數(shù)字信號；中斷系統(tǒng)支持IO個中斷向量以及l(fā)4個可來自系統(tǒng)時鐘、定時器／計數(shù)器、時間基準發(fā)生器、外部中斷、鍵喚醒、通用異步串行通信及軟件中斷的中斷源，非常適合實時應用領域；U’nSPTM的指令系統(tǒng)還提供具有較高運算速度的16位16位的乘法運算指令和內(nèi)積運算指令，為其應用增添了DSP功能，在復雜的數(shù)字信號處理方面既非常便利，又比專用的DSP芯片便宜得多。SPCE061A內(nèi)置8通道1O位模／數(shù)轉(zhuǎn)換器，其中7個通道用于將模擬信號(例如電壓信號)轉(zhuǎn)換為數(shù)字量信號，1個通道只用于語音輸入，即通過內(nèi)置自動增益控制放大器的麥克風通道(MIC—IN)輸入。因此，可以直接將語音信號送給此輸入通道，完成8kHz語音信號的采集、編碼并存儲到片外FLASH中，簡化了電路設計。凌陽SPCE061A單片機具有音頻輸出功能的雙通道IO位D／A轉(zhuǎn)換器可 以完成用戶訓練、識別等各種操作的語音提示。SPCE061A提供的音頻輸出方式為雙通道DAC方式，在此方式下，DAC1和DAC2轉(zhuǎn)換輸出的模擬量電流信號分別通過AUD1和AUD2引腳輸出，輸入的字分別寫入P—DAC1(寫)(0x7017)和P—DAC2(寫)(0x7016)單元。LED顯示器中每個發(fā)光二極管要通過5～20mA電流才能達到正常亮度，而SPCEO61A的IO口輸出電流可達到5mA，不用驅(qū)動電路即可達到正常亮度。系統(tǒng)為了滿足可靠性設計，采用晶體管構成驅(qū)動電路。整個顯示過
