摘 要

近些年来, 新兴物联网技术的飞速发展，很大程度上改变了人们的工作方式，同时也改变了人们的生活方式。众所周知，在许多生产生活场合中,温度都是一个具有重要意义的参数，而在很多场合中对温度进行实时监测是很有必要的。但是由于我们采用的多种对温度测量的方式方法存在安装困难、无法实现实时测温、准确性差、效率低等问题,所以我们迫切需要一种新的技术来代替传统测量。

本设计中选用WiFi技术作为各个采集结点无线通信方式，完成和无线路由器的通信，并可通过无线路由器实现和电脑（服务器）及智能云平台进行通信。上传采集到的温度数据（可以到达智智能云平台），以及接受设定的采集间隔时间（如：每秒采集次数等）。主要采用TI CC3200 LaunchPad开发板作为数据采集及控制端的微控制器，通过其芯片内置WiFi模块把数据上传至服务器，并从服务器返回控制信息。

Design of IoT system based on cloud platform-temperature acquisition and WiFi module programming

Abstract

In recent years, the rapid development of emerging IoT technologies has largely changed the way people work, as well as the way people live. It is well known that temperature is a significant parameter in many production and living situations, and it is necessary to monitor temperature in real time in many occasions. However, we urgently need a new technology to replace the traditional measurement because of the difficulties in installing the various ways and means of temperature measurement, the inability to achieve real-time temperature measurement, poor accuracy and low efficiency.

In this design, WiFi technology is selected as the wireless communication mode of each acquisition node, which completes the communication with the wireless router, and can communicate with the computer (server) and the intelligent cloud platform through the wireless router. Upload the collected temperature data (which can reach the smart Cloud platform) and accept the set acquisition intervals (e.g., number of collections per second, etc.). The TI CC3200 LaunchPad is mainly used as the microcontroller for data acquisition and control, and the data is uploaded to the server through the built-in WiFi module of the chip, and the control information is returned from the server.

Key words: Internet of things; temperature; WiFi Technology; CC3200 ;
