Design of Intelligent Switch Based on the AT89C51 MCU
ABSTRACT
People can more easily control devices with the occurrence of the emergence of
intelligent switches which has brought great convenience to people’s lives. The
microcontroller is constantly been used, and it is more extensive, the reason lies in its
low power consumption, easy to use, small size, some features. This design aims to do a
systematic study of the emergence of intelligent switch which based on the AT89C51
MCU of design theory and method.
the AT89C51 MCU play the core role in this design, and combined with peripheral
components the buzzer, relays, the DS18B20, digital tube, etc. by which design the
switch of control of the work and rest time and the air-conditioning temperature
monitoring and alarm function of the intelligent. the design using Protel software design
temperature data acquisition circuit alarm circuit, display circuit, the use of the Keil
software programming, Proteus simulation to achieve its function. this design is flexible,
simple to modify, and more secure in the process of using energy-saving
microcontroller to monitor real-time temperature. To a certain extent, not only improve
the function of the air conditioner, but also simplified the air conditioning control and
operation of the air conditioning .
Key words: MCU; Intelligent switch; DS18B20
