Design And Implementation Of Monitoring System For IOT Based On Restful Web Services

With the rapid development of computer technology and sensor network technology,the Internet of things has become an indispensable technology in people's lives.The application of smart home and digital home based on Internet of things technology is booming.In these application scenarios,the data collected by the sensing device come from different devices,different platforms,and the data are very different.The traditional centralized device monitoring and control method has the disadvantages of low efficiency and high maintenance cost in real-time data acquisition and distributed deployment.Web Services technology has the characteristics that do not depend on the hardware environment,distributed,cross operating system,and cross programming language,so it solves the problem of distributed data storage well.The Web Services technology based on REST architecture is suitable for massive real-time data distributed processing because of its stateless characteristics.This paper takes Restful WebServices as the technical basis,and takes the data of the perceived equipment in the enterprise Internet of things laboratory as the research object,and takes the enterprise Internet of things monitoring system as the research target.The monitoring system of the Internet of things laboratory is analyzed,and the monitoring and management system of the Internet of things based on Restful Web Services is designed.This paper proposes an approach to encapsulate device heterogeneity by means of REST Web Service and regard the device as a stateless resource access method.The functions of data acquisition,historical data query,equipment status monitoring and equipment data display are realized.Through this system,the cost of data management of the IOT monitoring system can be greatly reduced,and the efficiency of equipment management in the IOT environment is also improved.At the same time,the automation of equipment management of IOT is realized.
