Software Radio-based Data Acquisition and Transmission System

Aiming at the problems of insufficient flexibility and limited scalability of traditional telemetry devices, this paper designs and realizes a data acquisition and transmission system based on software radio. The system adopts a modular architecture design, integrating three major modules of multi-source data acquisition, data processing transmission, and reception reduction. Experimental results show that the system can realize accurate data transmission. Through the customized frame structure and UDP/IP protocol encapsulation, the system can accurately restore multi-channel acquisition data. This system provides a reconfigurable platform for wireless communication, and its modular design can be expanded to telemetry, sensing, and other engineering fields, which has significant potential for engineering applications.
