Application Of Multi Sensor Data Fusion Technology In Internet Of Things

With the development of sensor technology and networking technology,the tendency which minify the sensor impels it includes more sensors in the Internet,the data fusion and conversion between these sensors has become particularly important,so as to promote the development of multi sensor data fusion technology.This paper will explain the important role of the sensor in the Internet of things and multi-sensor data fusion technology in detail with the background of the Internet of things,and design a data fusion system based on least square method.In order to solve the problem of intelligent conversion between sensor readings and real physical quantities in the system of Multi sensorfusion,The way of using keyboard input to simulate sensor data to send several forms to simulate different sensor data after A/D conversion,and scale transformation model is established.In order to adapt to different requirements,we divide our model into Zero starting point scale transformation and Nonzero starting point scale transformation,then redact program which is accord with the above function in assembly programs.then using assembly to write programs to achieve the above functions.After the completion of the program,we use the download tools write the program to our core processor-AT89C52.When the functions of data transmission and data conversion have completed,we will use the 12864 LCD as the display device to show the result.
