The Design And Implementation Of Data Acquisition And Wireless Transmission System Based On CC3200

Data acquisition technology is widely applied in areas such as medical,military,remote sensing,telemetering and other fields.The development of sensor technology and wireless communication technology is to promote the development of data acquisition technique.The parameter information collected by the data acquisition system in the measurement and control system of an aircraft is very important to the development of aircraft and flight test.However,with the development of the aircraft,the type and quantity of the parameter data gathered by data acquisition system have become more and more serious.In addition,in order to collect these parameter information large amounts of sensors need to be distributed in every position of the aircraft to sense these parameters.In these conditions,the traditional cable data transmission methods cannot meet the requirements,in order to solve this problem,we design a data acquisition system based on WIFI wireless transmission.The design of the data acquisition wireless transmission system can collect the parameter information which is perceived by those sensors distributed in every position of the aircraft,and then the system transmits the data to the upstream center program for subsequent data processing.The system based on wireless sensor networks(WSN)technology and Wireless Local Area Networks(WLAN)technology to realize data acquisition and wireless transmission.The sensor node in the system takes CC3200 as the control core to obtain the parameter information sensed by the sensor,also the parameter data are framed and wireless transmitted by CC3200.In order to verify the correctness of the data in the wireless transmission process,we use PC to receive and analyze the parameter data.In this paper we first briefly describe the background and significance of the research,and then we make a simple exposition of related research status and development trend,then we briefly introduced the theory basis of the system,and then we put forward the overall design scheme of the data acquisition and wireless transmission system on the basis of the relevant theories,and then we introduce the structure of the system,hardware circuit,software programming and system testing in detail.Experimental results show that the design of data acquisition and wireless transmission system can realize the wireless access to the parameter information data perceived by those sensors distributed in the region to be monitored,and there is no data loss in the wireless transmission process.The system has high flexibility,good reliability of wireless data transmission,saving space and other characteristics.Also,the system meets the demand of practical application.
