Abstract In recent years, with the computer is used rather widely in our daily life, the application of SCM is going deeper and deeper, and controlling SCM is becoming more important.
In this thesis, the system hardware consists of power supply circuit、temperature acquisition circuit (DS18B20)、key board control system、LCD display circuit、control circuit and other auxiliary circuits. A detailed analysis which is about the applying of Microcontrollers and the applying of different parts made by different hardware and software in the system. This system can complete the temperature display, temperature settings, air-conditioning control,temperature alarm limits and remote control and many other functions. SCM system will receive the digital signal decoding processing, the temperature displayed by LCD1602, the SCM system will complete the keyboard scan button temperature setting, over-temperature alarm program processing, in order to achieve the air-conditioning intelligent.
