Design Of New Internet Of Things Architecture Based On Intelligent Potted System

With the rapid development of the Internet of Things(IOT),the concept of intelligent home,intelligent building and intelligent agriculture based on the IOT gradually into people's lives.But the current IOT architecture usually exist some shortcomings about difficulties of deployment and high cost of equipment,and the practical application ability is weak.In this paper,a new IOT architecture is designed for the shortcomings of current IOT architecture.The biggest innovation of the system is the addition of WSN on the basis of the traditional IOT,which connect objects within a certain area to a LAN.And an new Internet interface is designed,which connect the WSN and the Internet closely by Single Chip Microcomputer(SCM),.The part of the WSN uses the CC2530 as the transmitting node,and build on the basic of the Z-Stack protocol stack under the ZigBee protocol.This paper optimizes the mode of creating net of WSN,and has improved greatly in terms of practicality.And for the terminal node,through the design of sleep system and the optimization of transmission power,the power consumption has been greatly improved.The raspberry is used to connect the WSN and the Internet.On the one hand,the raspberry is connected to the CC2530 of the central node via the serial port to obtain the data of entire WSN.On the other hand,the raspberry is equipped with LAMP's web server and database architecture to provide Internet services and saving data.Through the design of intelligent potted system,this IOT architecture is applied to the actual smart home system.The part of sensors uses a variety of sensors to collect soil moisture data,soil temperature data,air temperature data and humidity data.In this paper,the method of measuring the soil moisture by measuring the soil resistance with temperature compensation is put forward.This method reconstructs the relationship between soil temperature,soil voltage measurement and relative humidity of soil on the basis of previous studies.It is proved that the method has good robustness,and its accuracy and application range of temperature and humidity have been improved remarkably compared with the results of previous studies.And then an App is designed for testing whole intelligence potting system.The new IOT architecture designed in this paper is innovative in the connection program between the IOT and the Internet.At the same time,it has also the character of low cost,low power consumption,accurate data measurement and so on.The architecture of the system can also be used in other things networking system,and provides a new form of operational and practical development for the future application of the Internet of Things system.
