【正文】 hrough 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, ~ F. Current surveillance function is to prevent the destruction of munication lines and electromagic actuator, for some reason the flow of electromagic coil currents too large burning coil. Current Monitor by MAXIM pany39。 u39。s integrated development environment, Can easily plete the design of hardware and software programming, thus achieving the abovementioned functions. Voice electronic code lock system is the core of speech recognition module. SPCE061A is Sunplus has developed a very high price of the 16bit microcontroller, embedded 2 K word of SRAM and 32 K word FLASH, with 32 programmable multipurpose I / O ports include 7 Channel 1 OGeneral A / D converter, builtin microphone amplifier, AGC AGC function of the single voice of A / D converter, and the audio output of the dualchannel 1 Obit D / A converter in the V ~ operating range of frequency range of MHz ~ , high processing speed enable it to easily and quickly handle plex digital signal。s voice through a microphone into the speaker voice signal acquisition frontend circuit, by voice signal processing circuit on the acquisition of the characteristics of voice signals and voice processing, from the speaker39。 FLASH 1 Introduction As people39。 1 畢業(yè)設(shè)計外文翻譯 Voice of Electronic Passwordlock Design 語音電子密碼鎖的設(shè)計 ： ***** ： 本科 ： 電氣與信息學(xué)院 ： ***** ***** ： ***** ： 副教授 學(xué)生姓名 學(xué)歷層次 所在院系 所學(xué)專業(yè) 指導(dǎo)教師 教師職稱 2 Voice of Electronic Passwordlock Design ( / JUN E 200 6 ) Abstract: The design is the use of voice recognition technology and keyboard input, Sunplus SPCE061A SCM in achieving a voice electronic password lock authentication recognition and electronic password lock function of the ordinary locks, and dual role of security. The password lock safe, effective, reliable, but also has voice recognition, password Preferences, confidentiality strong, tips and other features of error. Key words: SPCE061A。 voice recognition, electronic password lock。s living standards improve and strengthen the sense of sec urity, safety locks system bees essential, therefore a password lock, magic locks, electronic locks, laser lock, voiceactivated lock locks, etc., they are On the basis of trad
