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.
