Research And Design Of Intelligent Kitchen Based On Internet Of Things

With the development of economy,the Internet of things(IOT)technology has developed rapidly,and the intelligent kitchen system has been more and more used in people's life.According to the background significance of intelligent kitchen research and its present situation at home and abroad,the paper makes a brief description for content of the innovation,Internet of things technology and each layers functions of the Internet of things.On the one hand,contrast to the study of a variety of wireless transmission technology and their characteristics,paper selects ZigBee wireless transmission technology as Sensor Networks finally.On the other hand,the paper use star network as ZigBee wireless networking topology based on the overall function of the system,the function of ZigBee technology layers and Protocol standards.First,according to the previous analysis of the home gateway for the hardware and software design,Using STM32F407 chip as the main chip of home gateway to complete the home gateway peripheral circuit design,Using RS485 bus way to communicate with the coordinator,Using Wi-Fi way to connect with the external network,Using color screen for human-computer interaction.Second,according to the previous analysis of the ZigBee network for the hardware and software design,Using CC2530 chip as its main chip both network coordinator and node control chip.Third,according to the previous analysis of sensor modules at the node for hardware and software design,including camera module,wireless infrared temperature measurement module,temperature and humidity acquisition module,pyroelectric module and so on.In the course of the experiment,to begin with,dealing with debugging the process of the various problems,and then tested the performance of the module,and finally tested the overall function of the experiment.Experimental results show that the system can achieve the expected purpose.It solves the defects of traditional kitchen monitoring system which the user can achieve monitoring of children,gas stove monitoring,intelligent kitchen mouse detection,locker temperature and humidity monitoring by the intelligent kitchen remote terminal.This article designed based on the Internet of things intelligent kitchen more advantages,not only eliminates the cumbersome wiring,increases the degree of intelligence and improves the kitchen safety performance,but also increases the protection function for the children.
