Abstract
Along with the progress of science and technology in China and the
improvement of people's living standard, in recent years, various industries are
developing rapidly, also including air conditioning industry. Air conditioning has been
widely used in public places, special field and ordinary families and so on. The main
task of this thesis is the design of air conditioning controller based on FPGA, the
controller part adopts Verilog HDL language. Main program state machine is adopted
as the main control mode, hardware module mainly has buttons, 50 MHz
semiconductor vibration module, digital tube display module, temperature sensor,
humidity sensor module, air conditioning actuator module. Finally, taking FPGA as
the core control device, set by comparing the acquisition of temperature and the
temperature to make users send cooling or heating control signal to air conditioner.
Set by comparing the acquisition humidity and humidity to make user control signal
humidification or dehumidification for air conditioner. At the same time through the
FPGA chip can achieve timing and control the use of digital tube display, temperature,
humidity sensor, the set temperature, time, displayed, finally timing simulation using
Quartus II software.
The subject of the research will contribute to adopting FPGA series product
development, at the same time can shorten the development time of FPGA. In
addition, due to the ease of modules, will make more designers using FPGA products
applied in the field, temperature control for the industry and bring new changes in our
lives.
