Abstract

The ideal energy-saving building should meet the environmental quality of living space in different seasons with the least energy consumption. The indoor temperature of the building is an important consideration. However, most temperature control systems have certain problems. In order to improve the stability and accuracy of the temperature control system, a system based on FPGA+Verilog HDL for intelligent adjustment of indoor temperature is designed. The purpose of the system design is to achieve the dual effect of comfortable and energy-saving living environment. The system uses an integrated temperature sensor DS18B20 as a temperature sensing element. FPGA as the master control center to process data. The system is programmed with the hardware description language Verilog HDL. The temperature control system uses a digital PID control algorithm. The simulation results verify the correctness of the design.

Summary

Introduction

The ideal energy-efficient buildings should meet the environmental quality of living spaces in different seasons with minimal energy consumption. The main ways of building energy conservation include: reducing the energy loss of building envelopes; reducing the energy consumption of building facilities; minimizing the consumption of non-renewable energy and improving the efficiency of energy use. In these aspects, high technology plays a decisive role. This paper designs a system based on FPGA that uses the serial port to transmit data, which can intelligently adjust the indoor temperature It maintains the comfort of living, and saves energy, achieving the dual effects of comfort and energy saving. Using FPGA to realize the design of temperature control system can improve the computing speed of the system, reduce the volume of the system, and enhance the reliability of the system, and has a strong application prospect
