The Software Design And Implementation Of Internet Of Things Experiment System

With the continuous development of information technology,The Internet of Things(IoT)is predicted to be another wave of technology and economy of the global information industry after the Internet,It has received the attention of governments,enterprises and academics.Rely on the Internet of Things human beings can be more sophisticated and dynamic way to manage production and life,to achieve "wisdom" to improve resource utilization and productivity levels.The research and development of core technology and typical application of Internet of Things has become a new direction of teaching and scientific research.In order to make the students understand the principles of the Internet of Things and how to realize it,this paper realizes an experiment system of things.In this paper,the experiment system of the Internet of Things is designed with temperature and humidity,distance and other sensor module experiments;RFID experiment;Bluetooth,ZigBee,WiFi and other modules of data transmission experiments;Through the research of device driver and Qt/Embedded under Linux system,the software part of experiment system is designed and realized.(1)This paper introduces the design of Linux device driver.According to the basic principle,we design the driver of each module of the experiment system,including RFID module,sensor module and wireless transmission module.It realizes the recognition of the module.(2)Including interface design and function realization,such as temperature and humidity experiment,WiFi,Bluetooth transmission,and so on.At the same time,this paper introduces the design of embedded GUI and Qt technology,according to the experimental requirements.(3)Test the experimental system of various experimental functions,including temperature and humidity testing,Bluetooth,voice intercom and other experiments,are all to achieve the desired results.After being put into use for a period of time,through the experimental system to carry out a variety of basic experiments,comprehensive experiments and students of independent innovation experiments.
