摘要：随着人民生活水平的提高和社会生产技术的发展，空调越来越普及。空调是一种大功率电器。在如今这个倡导节能环保的社会里，空调也需要采取相应的节能措施。主要是夜间人休息后空调的自动调节功能。这是我们设计酒店空调系统方案及系统优化时必须要考虑的问题。

酒店空调节能系统涉及了多方面的设计，包括单片机系统，温度的采集系统，红外线遥控系统以及液晶显示系统等。本文硬件部分主要包括电源电路，STM32单片机内部电路，DS18B20温度采集电路，红外遥控电路，液晶显示电路以及背光控制电路等。软件部分主要在keil下进行C语言程序的编写、调试以及后续仿真工作。在此基础上完成节能控制的设计目的。

Title  Hotel air conditioning energy saving system design

Abstract：With the the improvement of living standards and development of production technology, air conditioning is becoming more and more popular. Air conditioning is a high-power electrical appliances, in this vigorously advocate environmental protection and energy conservation society, for air conditioning, but also need to take the appropriate energy-saving measures. The main function is the automatic adjustment of the air conditioner after the night rest. This is the problem that the hotel air conditioning system design and optimization must be considered.

Hotel air conditioning energy-saving system involves a wide range of design, including SCM system, temperature acquisition system, infrared remote control system and liquid crystal display system.In this paper, the hardware part mainly includes power supply circuit, STM32 microcontroller internal circuit, DS18B20 temperature acquisition circuit, infrared control circuit, liquid crystal display circuit and backlight control circuit The software part mainly carries on the C language programming in the KEIL, the debugging as well as the following simulation work. On this basis, the design goal of energy saving control is completed.

Keywords: Air conditioning energy saving; STM32; DS18B20; infrared remote control; keil
