However, with the increasing number of airconditioning , the corresponding negative issues appeared, increasing energy consumption has bee one of the energy and electricity supply and demand in some areas of the main reasons , it is imperative to take effective measures to reduce the energy consumption of air conditioning . How to reduce air conditioning energy consumption for air conditioning automatic control , the use of air conditioning to improve the indoor temperature and prolong the life of air conditioning has bee a priority issue. This paper describes the design of air conditioning controller presents a method using field programmable gate array device FPGA controller for air conditioning , which is designed using Altera39。s high cost FPGA, CycloneIV series EP4CE6E22C8 master controller, using highprecision temperature collecting the ambient temperature sensor DS18B20 , LCD1602 display control for temperature conditions , with the temperature and timing adjustment control buttons , LED lights simulate airconditioned motor state , this design gives the Verilog HDL language used to achieve high efficiency air conditioning controller design , Finally its implementation in FPGA hardware Keywords: air conditioning controller， FPGA， CycloneIV， Verilog HDL 《優(yōu)秀畢業(yè)論文》 基于 FPGA 的空調(diào)控制系統(tǒng)設(shè)計 IV 目錄 摘要 .....................................................................................................
