本文设计一种模型自由飞低时延无线传输系统。该系统以FPGA为主控制器,采用A7196与ESP32C3进行数据的无线传输。根据系统数据传输要求,采用短帧的方式发送数据,降低了传输的时延,基于李雅普诺夫方法设计了无线传输程序,保障了传输的稳定性。测试结果表明:传输系统可靠性可达99.907%,上行传输时延小于1 ms,有效实现了对自由飞模型的无线控制,代替了原有的有线电缆连接方式,简化了实验准备过程。

A model free flight low-latency wireless transmission system is designed.The system uses FPGA as the main controller,and uses A7196 and ESP32C3 for wireless transmission of data.According to the system data transmission requirements,data is sent by short frames,which reduces the transmission latency.A wireless transmission program is designed based on the Lyapunov method.And the stability of transmission is guaranteed.Test results show that the reliability of the transmission system can reach 99.907 %,and the uplink transmission latency is less than 1ms,which effectively realizes the wireless control of the free-flying model.It replaces the original wired cable connection mode,and simplifies the experimental preparation process.
