Low-Power Modular UAV Data Acquisition and Transmission System Based on Advanced Compression and 4G Communication

Audio extraction systems have important applications in the field of uncrewed aerial vehicles (UAVs), especially in the areas of disaster emergency response, environmental monitoring and precision agriculture. However, the large size and high power consumption of existing systems limit their widespread use. In this study, a UAV information acquisition and transmission method based on low-power sensing and 4G remote transmission technology is proposed, aiming to achieve efficient processing and transmission of audio data while meeting the requirements of miniaturization and low power consumption. The system adopts a modular design and achieves low power consumption and efficient data transmission by optimizing the collaborative work between the front-end hardware and the back-end cloud platform. Experimental results show that the system exhibits high stability and significant low power consumption in complex environments (the lowest power consumption is 0.1 mW), while the transmission efficiency is significantly improved over traditional methods (the average rate reaches 4.5 Mb/s). This study provides reliable technical support for the application of UAVs in complex missions.
