Design And Implementation Of Communication Protocol For Micro-environment Monitoring Platform

By using wireless sensor network technology and Internet of Things technology to monitor multiple specific small-area micro-environments,regional environmental data can be derived to provide decision-making for life production.In order to solve the problem of micro-environment monitoring,the business application is different but the same sensing layer and network layer are repeatedly constructed,and the data collection and transmission difficulties caused by the inconsistency of a large number of heterogeneous data formats,the following work is carried out.1)The three-layer architecture for the Internet of Things is designed to design a general micro-environment monitoring platform that unifies the sensing layer and the network layer,and can perform different business applications on this platform.After expounding its overall structure and various key parts,this paper draws on the research work of data acquisition and transmission,and at the end of the paper,the prototype system is designed and implemented for the data acquisition and transmission part of the micro-environment monitoring platform.2)For the data collection research work in the platform,this paper designs and develops a general micro-environment monitor from both hardware and software.Through the selection and design of various hardware components,unified communication protocol design and the design of heterogeneous information-aware middleware,the instrument can automatically collect heterogeneous data and unify heterogeneous data formats with lower power consumption,improving the efficiency of environmental monitoring.3)After the data collection is completed,the communication quality of the sensor network,the mobile network,and the Internet for data transmission is ensured by designing the communication protocol and the communication negotiation process.Complete the software development of the host computer,complete the transition from the sensor network to the Internet through the gateway and the host computer,and finally complete the entire communication transmission process from the micro-environment monitor to the gateway to the host computer and finally to the server.By testing the system prototype in the real environment of the campus,the results show that the research work provides a unified data acquisition device for the micro-environment monitoring platform,a unified communication protocol,a unified data expression and transmission scheme is stable and feasible,and can be more Timely,accurate,effective and safe integration and uploading of source,multi-class and multi-type massive data.It can be further upgraded and improved to make the program form a practical micro-environment monitoring platform,which has a good application prospect.
