Air Conditioner Controller Based On SCM

ABSTRACT

Air conditioner is an electrical type air conditioning apparatus,and is the abbreviation of air conditioner.It has conditioned air temperature and humidity, and air filtration, air circulation, ventilation and other functions, so that people can live and work in a clean and comfortable environment.In recent years, with the air-conditioning function of improving people's living standards and the increasingly high demand for air conditioning has a lot of different styles into the home. Feature-rich, full range, high degree of automation become the new target for the development of air conditioning.

The design of AT89C52 micro-controller as the core, to achieve the air-conditioned indoor temperature controller detection and adjustment, the ultimate goal is to have a stable work performance and functional requirements. The hardware of the system is pided into an input module, display module, stepper motor control module, the temperature sampling module.Software part is pided into the main program module, a temperature controller interrupt subroutine modules,  digital display subroutine modules, the cycle timer interrupt subroutine modules, stepper motor control subroutine module. Through the micro-controller of  the  data acquisition, conversion, operation, output, completion temperature display, temperature setting, air-conditioning compressor start and stop functions. ADC0809 the analog signal from the temperature  sensor (voltage  signal) into a digital  signal into the micro-controller port P0, the micro-controller will receive the input data is compared with the external temperature to determine the work status of the AC motor. Controller for overall system design argument further described SCM application process in the actual system.a comprehensive analysis of the various parts of the hardware and software system implementation.
