Applied Research On Cyber-Physical Systems Based On Internet Of Things Technology

At present,China is in a critical period of economic transformation and upgrading,characterized by the convergence and interchange of old and new industries.With a new generation of information technology to promote the upgrading of traditional industries,nurturing new industries is the key to the success of the transformation.The concept of Cyber-Physical Systems has been proposed for the first time since 2006,which is expected to become the third wave of the world information technology after computer and Internet.The Cyber-Physical Systems(referred to as CPS)as a unified body of computation and physical processes integrating computing,communication and control,are the next generation of intelligent systems which in the future can be widely used in industrial production,logistics,aerospace,traffic,health care,environmental monitoring,national grid and home life,etc.Based on the Internet of Things technology,this thesis studies the application of Cyber-Physical Systems from three aspects.(1)Taking the advantage of Cyber-Physical Systems,this thesis focuses on how to improve the operation efficiency of container yard and the automation level of the yard from the aspects of mechanical equipments and yard management.A smart container yard based on visual sensing has been designed.To improve the operation efficiency,a yard storage optimization model has been established.And the PSO algorithm has been used to solve the model.(2)A typical application of Cyber-Physical Systems is the field of smart home.This thesis,aiming at the demands of general public,studies a smart home system,which is low cost,multifunctional,modular,extensible and easy to install.A multi-mode perception-control module based on wireless sensor has been designed and to improve the efficiency,multi-equipment integration based on custom protocol has been proposed.The studied system,monitoring the indoor environmental parameters,establishes the interconnection among audio-video equipment,computer,lighting,security equipments and other common equipments,to enhance the safety and comfort of home.(3)Considering the background of the current environmental problems,the application of Cyber-Physical Systems in air quality monitoring is studied.In this thesis,a distributed air quality monitoring network model based on Hadoop is designed,which can effectively eliminate the vulnerabilities and monitoring information island easy to be caused by the traditional monitoring methods by unifying the monitoring data collection,storage and analysis,to make "valuable data"better serve the environmental monitoring work.
