基于FPGA的控制器设计 学生专业： 电子信息科学与技术 Abstract Along with the progress of science and technology in China and the improvement of peoples 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.
