[Abstract]:With the development of storage wireless data acquisition system, its application scope is more and more extensive, and the requirements of each performance index are more and more strict. The current wireless data acquisition system generally has the disadvantages of low transmission rate, small coverage range and large power consumption. Based on this, this paper proposes the design and implementation of embedded wireless data acquisition system. Based on the research status of wireless data acquisition system at home and abroad, this paper puts forward the design scheme of embedded wireless data acquisition system by analyzing the technical indexes and functions of the test system. The software and hardware of the module are designed. Firstly, this paper analyzes the current situation of wireless data acquisition system at home and abroad, introduces the principle and theory of designing data acquisition system. Based on the linux system, the driver is designed in ARM by C language. And completed the development of the application program of the whole data stream transmission, including WIFI driver, EBI bus driver, socket communication program, data encryption program, USB communication and so on. This paper introduces the hardware realization process of embedded wireless data acquisition system. Through the analysis of the data collected by the test system, it is proved that all the indexes in the system have reached the expected requirements. Using ARM9 and FPGA together, the communication circuit can be used directly in the future project development, which greatly shortens the period of project development. At the end of the paper, the shortcomings of the test system are explained in detail, and the application prospect of the test system is prospected. The wireless data acquisition system combined with ARM9 and FPGA has been successfully applied in the development of a project.
