基于ARM的嵌入式智能家居远程监控系统设计.

摘要

科技改变生活，科技为人类带来了更舒适更方便的解决方案，智能家居是现代化科技的体现，智能家居也正是在应人们需求下而产生的。

本设计的内容是设计一个基于ARM的智能家居远程监控系统。整个硬件控制系统有以下模块：控制主机STM32F103VET6、无线短信收发模块GPRS(远程监控的主要模块)、用于显示的LCD1602液晶显示屏(显示测量出来的温湿度值)、测量外部环境温湿度的温湿度传感器DHT11，异步电机28BYJ-48(模拟控制窗帘收放用到的控制器)、蜂鸣器(报警用)、LED灯(模拟室内各种灯)、继电器(模拟室内各种电器的控制开关)。

温湿度传感器测量出来的温湿度数值通过LCD1602来显示，当超过设定的阈值将通过GPRS模块发送警报短信到指定的手机上，同时也可以由手机发送特定短信到GPRS上控制LED灯的亮灭、控制28BJY-48步进电机的正反转、读取当前室内的温湿度并发送回手机上，实现远程监控的。

Abstract

Technology has changed life, science and technology has brought to mankind more comfortable and more convenient solution, smart home is a manifestation of modern technology, smart home is also in demand should be generated by people.

The content of this thesis is to design a remote monitoring system of smart home based on ARM. The entire hardware control system has the following modules: the host controller STM32F103VET6, wireless SMS transceiver module GPRS (the main module of the remote monitoring), LCD display (to display the temperature and humidity measured values), temperature and humidity sensor,DHT11, be used to measure the external environment temperature and humidity, asynchronous motor

28BYJ-48 (analog controller curtain used), a buzzer (alarm), LED light (simulated indoor lamps), a relay (control switch simulation of indoor each kind of electric appliance).

The temperature and humidity value measured by the temperature and humidity sensor and displayed by LCD1602, when more than a set threshold an alarm SMS will be sent by GPRS module to the designated mobile phone, but also can be caused by the mobile phone to send a specific message to the GPRS to control LED light, 28BJY-48 stepper motor reversible, read the current indoor temperature and humidity and sent back to the mobile phone.
