Wireless Temperature Measuring System Base On Blue Tooth Technology

This project analyse the pain point of the induction cooker product from the view of the users,figure out an common bottle-neck problem in the induction cooker field:the temperature detection of the pan is not in time and not accurate lead to the unsatisfactory cooking performance,so that the use of the induction cooker is limited enormously?In order to end this problem,this project design a wireless temperature detective system which is based on the blooth technology.This system adopt a new method to detective the temperature,enhancing the accuracy,and also,the most important,using the blue tooth technology as the way of transmitting the temperature dates.In the meantime,the system design the cell phone APP which can down load the recipes to cook automatically.This project is very meaningful,it will be the foundation of revolution in the future Induction cooker industry.As the core of this system,bluetooth is an open wireless local network protocol.It provides the possibility for RF connection of speech sound and data transmission of information equipments in limited distance.This technology replaces the dependency of equipment on cable.At the same time,it can make connection equipments into network model and thus work properly.The most important reason for the widespread attention on bluetooth is that it is the global standard for wireless connection.Its formulation is based on its replacement of cable,simple operation,and stability.These requirements not only impose new many challenges,but also supply a good number of opportunities.This technique employs FHSS,and its design demands minimum assumption,lowest cost and superior property of anti-interference.It includes RF unit,baseband CCU,connection software,and some respective super functional software.This System based on the NXP-developed DXYBT021 Bluetooth module QN9021,which is produce by Shenzhen Dingxin Infinity Technology Co.,Ltd,and finally design and develope the hardware circuit,according to relevant information,using Bluetooth technology to achieve The Induction Cooker wireless temperature measurement system,basically achieved instant temperature measurement and Bluetooth wireless data transmission functions,and achieved quite good experimental results.This system will be bringed put into the market,it will Realize accurate temperature measurement and temperature control of Induction Cooker products,safe and reliable transmission of wireless data,and expand the application of Induction Cooker.The article including five parts.the first part is introduction,mainly about the background of the project.The second part is about the basic Bluetooth theories,including the characteristic of the Bluetooth technology,and the Bluetooth wireless protocol and baseband protocol,as well as the network control,information channel and so on.the third part introduce the total framework of the system design,including the design of the hardware and software.the fifth part is the summary about the project and some plan about the future research work.
