Design And Implementation Of Wireless Sensor System Based On CC3200

With the continuous development of electronic technology,wireless communication is undergoing rapid changes.In modern social life,wireless communication has become an indispensable part of people.Compared with traditional wired transmission,wireless communication has broken the constraints of cable and weight,overcoming the high cost,inflexibility and walking of traditional communication methods.Various shortcomings such as complicated lines and poor mobility.At the same time,with the continuous updating of wireless communication technology,wireless communication has been applied to all walks of life and people's daily life,gradually improving people's living standards and accelerating the rapid development of society.This thesis first analyzes the research background and research significance of the subject,and introduces the development trend of wireless communication at home and abroad,and explains the future development trend and research significance of wireless communication.By comparing the advantages and disadvantages of various wireless communications,Wi-Fi technology is selected as the communication method of the wireless system.The wireless sensing system designed in this thesis is CC3200 as the wireless data interaction module,and STM32 as the acquisition module of sensor signal.The router is used as the "relay" for data and command transmission,and the microstrip antenna is used as the transmission medium for wireless communication.The sensor signal acquisition and transmission is realized,and a complete wireless sensing system is built.The main contents of this thesis are wireless networking,microstrip antenna design,system hardware circuit design,system software design and testing of system functions.The wireless networking analyzes the fat and thin AP,selects the fat AP as the networking mode of the wireless sensing system,and assigns 1,6,11 as the channel for wireless communication.The system hardware circuit design mainly includes design acquisition,conditioning,power supply hardware circuit,and detailed analysis of the requirements and precautions of the wireless sensor circuit board layout.The microstrip antenna obtains the basic parameters through simple calculation,through the software ANSYS18.0 Optimize the design of each parameter.The system software design includes analysis of TCP/IP protocol analysis and research,UART data interaction program writing in CC3200 wireless communication module,call and design of wireless network configuration program,design and writing of STM32 sensor signal acquisition and data processing program,and wireless router system function.Configuration and modification of Ser2 net programs and downloads,as well as program design for receiving and sending instructions.Finally,this thesis tests each module in the wireless sensor system,including antenna functional test;CC3200 sensor circuit board communication,acquisition,limit speed and other functional tests;the network mode uses three routers,test three The function of the route and the test of the limit speed;the verification test of the entire system.The test results show,the wireless sensing system designed in this thesis can not only realize real-time transmission,but also realize the accuracy of data interaction.The whole system has fast transmission speed,long transmission distance and high stability,which meets the requirements of project indicators.
