Research And Implementation Of ARM-Linux-based IoT M2M Middleware

With the rapid development of the Internet of Things industry,especially the establishment of Narrowband Internet of things(NB-IOT)standard,society is entering the era of interconnection of all things.The industries,such as vehicle monitoring,intelligent meter reading,intelligent tracking,will involve the problems of transmission and processing of terminal data,which is becoming the industry's hot spots.M2 M business management platform provides a unified management for terminal access,control,business processing.Due to the heterogeneity of terminal equipment and the diversity of data acquisition,the data interaction between M2 M platform and terminal equipment becomes extremely difficult,and M2 M middleware can effectively solve the problems of communication and data processing between management platform and acquisition terminal.Based on the ARM-Linux system,this thesis studies M2 M,and then designs and implements the related modules of M2 M Middleware.The main research and development is as follows:1.This thesis first introduces the concept of Internet of things and analyzes the development of M2 M middleware and the main problems,and then studies the ARM-Linux system and introduces the relevant technical background.2.Based on the analysis of system function and performance,this thesis puts forward the overall design scheme of M2 M middleware based on ARM-Linux,and then designs and implements terminal access management module,protocol analysis module,business processing module and application program interface module.Among them,the terminal access management module is to achieve the seamless access of heterogeneous terminal,long connection and other functions;protocol analysis module is to achieve a unified analysis of the original data;business processing module is to achieve a unified data classification processing with chain hash table method and send the instruction package for M2 M management platform;application program interface module is to achive a variety of interfaces for the M2 M management platform application layer.3.Combined with the logistics vehicle monitoring system,the M2 M middleware designed and implemented is tested and verified.The results show that the M2 M middleware designed in this thesis can effectively realize the remote monitoring of logistics vehicles,and it can provide a stable,flexible and convenient solution for the terminal access of enterprise M2 M business management platform.Finally,the work done in this thesis is summarized,and the shortcomings are pointed out.The work of the next step is forecasted.
