摘　　要：针对物联网硬件设备多样性、差异化、开发环境部署繁琐过于复杂的问题,本文设计并实现了面向云环境的敏捷物联网应用开发平台.该平台包括应用层、服务层以及设备层,具有在线编程、远程下载、自动运行等功能.并且针对远程下载功能,设计并实现了一套基于MQTT协议的代码在线推送方案及配套实验套件;针对用户及设备安全性问题,设计了一种基于TEA加密算法的动态口令认证方案.实测表明,平台实现了预期功能,达到了降低用户学习门槛以及提高开发效率的目的.Beginners have been facing challenges in IoT development and applications due to the existing hardware diversity and complexity.The deployment under current circumstances proves to be inefficient and error-prone.To address this issue,an agile development platform for IoT in cloud environment is proposed.The platform is designed to achieve functions including the cross-device,interpretive execution,online running,etc.To implement the online code downloading,a fine-tuned MQTT protocol is adopted.In addition,a set of experiment kits are designed as a supporting system,all of which serve the functions of online coding and the real-time running on devices.To reduce risk of the access of unauthorized devices and the leak of user information,an authentication method based on the TEA encryption algorithm is presented.Compared with existing schemes,the platform has the advantages of simplicity,friendliness,and can improve the efficiency of IoT development.
