Based On Embedded Wireless Data Acquisition System Design And Implementation

With the deposit of the continuous development of wireless data acquisition system, thescope of its application more widely, the performance requirements become more and morestringent. Wireless data acquisition system prevalent in the current transfer rate is slow,coverage, power consumption and other shortcomings, the paper put forward on the basis ofembedded wireless data acquisition system design and implementation.In wireless data acquisition system on the basis of the research status by analysis of thetechnical indicators and function test system, the design of embedded wireless dataacquisition system, and completed the modules in the system software and hardware design.The paper first analyzes the status of wireless data acquisition system at home and abroad, theprinciples and theories of design data acquisition system, linux-based system based on the useof C language completed within the ARM design for each driver, and completed the entiredata stream transmitted application development, including WIFI drivers, the EBI bus thedriver, socket communication program, the data encryption program, USB communication.The paper describes the hardware implementation of the embedded wireless data acquisitionsystem, the analysis of the data collected by the test system, confirmed the indicators havereached the expected demand in the system, the system design process ARM9and FPGA usedin conjunction with future development projects, the communication circuit design, greatlyshorten the development cycle of the project.The end of the article on the inadequacies of the test system is described in detail, and theapplication prospects of the test system were discussed, the system ARM9and FPGAcombination wireless data acquisition system has been successfully applied to a development.
