Household Air Conditioning Temperature Controller Design And Simulation Based On Verilog HDL
Abstract:Air conditioning temperature control has broad application prospects for industrial and daily life.This paper based on the hardware programming language, Verilog HDL design of household air conditioning temperature control system, It consists by temperature module, mode selection module and cross-border alarm module .Firstly,it introduces development tools such as Verilog HDL, Quartus II and Modelssim, that the subject involves, Secondly , it analysis the overall design of the whole system framework, and then points module introduces design idea. Then, it uses the Quartus II input simulation test to test the correctness of the function of each module, and uses the hardware circuit board to testwhole system. Finally, through the pinout .We use the system hardware circuit to simulate, and use the keyboard to settemperature and choose the work mode, to make the system workautomatically. we make the temperature over upper and lower bounds and alarm indicator.
