Design Of Kitchen Environment Monitoring System

The development of science and technology often brings new technologies.In the context of the global Internet,the Internet of Things technology is developing most rapidly among the emerging technologies in the 21 st century.It is more and more applied in all walks of life in the society,along with its development,there is also the smart home industry.As the pace of life is faster and faster,the pressure that people bear is bigger and bigger,the desire to body and mind comfortable is stronger and stronger,intelligent household also walked into the life of more and more people.Of course,not only do people want their homes to be comfortable and smart,but they also want them to be more secure.As a part of the smart home,the smart kitchen environment monitoring and control system is also one of the standards to measure the comfort of the house.Based on Zigbee wireless communication technology in the Internet of Things and combined with raspberry PI hardware,this paper designs a kitchen environment monitoring system to complete the real-time collection and view of the residential kitchen environment.The main tasks are as follows:(1)Put all kinds of sensors on the Zigbee module whose main control chip is CC2530 as the terminal child node of the kitchen environment monitoring system,and be responsible for the collection of kitchen environment data.The control device on the terminal child node will act immediately when the data collected by the sensor is abnormal to achieve the purpose of controlling the kitchen environment.The data on the terminal node will use Zigbee wireless communication technology to send the collected environmental data wirelessly to the Zigbee coordinator with CC2530 as the main chip through Zigbee internal protocol.(2)Select raspberry PI as the gateway of the whole monitoring system.The gateway is responsible for collecting data when connected with the coordinator,and for building a Web server to realize data uploading and storage.This system uses the way of USB port to serial port to realize Zigbee coordinator and raspberry PI gateway hardware connection.(3)Based on the open source Linux operating system of Raspberry PI,the software combination of Nginx as a Web server,My SQL as a database and PHP as a scripting language,the system builds a lightweight and open source Web server based on the basic architecture of LNMP on the raspberry PI hardware.When the Raspberry PI receives the environmental data sent by the Zigbee coordinator,the data is uploaded to the Web server through the Raspberry PI for storage.Users can also check these data at any time through raspberry PI’s network IP address to achieve the monitoring of the kitchen environment.The kitchen environment monitoring system designed in this paper can not only have an accurate,real-time grasp of the kitchen situation,but also can prevent the occurrence of kitchen accidents to a certain extent.Fig [64] Table [4] Reference [61]...
