The design of electronic music doorbell based on Single Chip Microprocessor
Abstract
With the progress of the times and development of intelligent control,small machines, micro-power consumption get a wide concern. In these areas,Single chip microprocessor played a pivotal role,which the MCU applications important to enhance the status of Single Chip Microprocessor applications designed to become the new hot technology.
In recent years,with intelligent buildings on the market has been heating up,the doorbell system has been as intelligent office and intelligent residential quarters of an important component of the traders and users to accept. People have begun to use doorbell system used to replace the traditional iron keys to manage the access door, rang the doorbell so that this system has been leap of development. With the rapid development of Single Chip Microprocessor technology,people will increasingly become an important future development direction, through the material life of the meet.
It is introduced by the AT89C51 chip to a system of electronic music doorbell process. This system is mainly to complete the electronic doorbell rang the doorbell not only a common electronic features, but also has some extensions. Its work by the state to set its own users, such as conventional capabilities, and visitors to provide the necessary response to the voice and text information, in addition, users can also visit a wide range of information enquiries.
