基于包分集的短程无线遥测系统

Long-range Monitoring System Based on Packet Diversity

在短程无线遥测系统中,需要对被测物体的运动情况进行测量。但无线通信场合下,要进行数据接收就会遇到信号丢失的问题。本研究在无线信道衰落以及丢包的情况下,利用分集接收技术显著改善了信号丢失问题。然后,在分集接收模型的基础上,搭建了分集接收的应用系统,并进行了实验。实验结果表明,基于包分集接收的模型可以有效改善短程无线遥测系统的丢包率,在需要进行无线动态测量场景中有良好的应用前景。

In the short-range wireless telemetry system, the need for accurate measurement of the movement of the object to be measured, in the wireless communication occasions to receive data will encounter the problem of signal loss, the decline in the research of wireless channel and packet loss under the condition of re- ceiving technology can effectively improve the signal-to-noise ratio by using diversity. Based on the research of diversity reception model, the application system of diversity reception is set up and the experiment is carried out. The experimental results show that the model can effectively improve the packet loss rate of the shortrange wireless telemetry system, and has a good application prospect in the wireless dynamic measurement scenarios.
