摘要:随着现在生活的日益提高，市场上出现了各种各样的防盗器材。但是很多都难以满足人们对防盗的需求。且人机界面不够完善，防盗设施不够智能等问题慢慢的浮现了出来。人们想需要更加完善更加智能的防盗设备。密码锁是日常防盗中常用到的工具或产品。目前的市场上已经出现了各种密码锁，但是由于其的可靠性和使用局限性等问题的存在使其不是很理想，且单一的密码防盗已经有些不切实际，故开发一种基于单片机SPCE061A与AT89S52相结合的语音识别与语音控制密码锁系统。

　　　它有很强的智能性和可靠的密码和语音识别双重防盗的功能。还有智能性很高的语音控制功能，它可以说主要由4个模块构成，分别是语音控制与识别模块，密码锁模块，声控灯模块，和人体热释电红外传感器模块构成。他的原理是首先进行语音训练，通过语音训练提取语音样本，随后整个系统开始运行。首先可以通过语音控制开启密码锁，并可以通过语音控制开启路灯。还可以通过语音开启或关闭人体热释电红外线传感器。可用语音开启路灯不是有声音就可以开启要发出相应的控制命令。语音开启密码锁后只有输入密码才能将开启门。密码错误进行报警，密码锁正确后可进行密码修改。而如果热释电红外传感器开启有人靠近感应区域同样产生报警。如果语音识别未成功无法对所有模块进行控制。

Abstract:Along with present life day by day, a variety of anti-theft equipment appeared on the market. But many are difficult to satisfy the people to the security needs. And the man-machine interface is not perfect ,security facility is not intelligent enough problems slowly emerged . People need more perfect more intelligent anti-theft device. The cipher lock is a daily alarm used in the instruments or products. The current market has seen a cipher lock, but due to its reliability and limitations of issues such as the existence of which is not very ideal, and a single password anti-theft has some unrealistic. Therefore developers based SCM SPCE061A and AT89S52 combination of voice recognition and voice control of the cipher lock.

     It can realize the speech recognition function to improve the reliability of the cipher lock system. It has very strong intelligence and secure password and speech recognition dual anti-theft function. There are intelligent and very high voice control function. It can be said that mainly consists of 4 modules, Are the voice control and identification module, password lock module, Lamp module, And human body pyroelectric infrared sensor module. His principle is the first voice training, speech training speech samples by extraction, then the whole system running. Firstly, through the voice control to open a combination lock, and can be opened by voice control lamp, also through the speech to open or close the human body pyroelectric infrared sensor. Available speech opening lamp not having sound can begin to issue the corresponding control commands. Voice open the locks only after entering the password to open the door, password error alarm, the cipher lock can modify your password correct . And if the pyroelectric infrared sensor open someone close to also generate alarm. If speech recognition without success to all control module.
