基于LoRa的数据传输技术研究

Research on Data Transmission Technology Based on LoRa

受通信环境的影响,在传统的数据传输技术下,丢包率会随着通信距离的增加而升高,直接导致数据传输效率低下,为此提出基于LoRa的数据传输技术研究。首先,在确保LoRa技术覆盖范围全面的基础上,设置TDMA组网协议;其次,为促使数据传输在低功耗下正常工作,选择基于芯片SX1276的LoRa调制解调器,并确定相关参数;最后,通过运用程序函数实现LoRa技术下数据的高效传输。根据模拟实验的对比结果可知,在传输距离为5000m以及发包个数为2000的前提下,基于LoRa的数据传输技术丢包率最低,仅为4.7%。

Affected by the communication environment,under the traditional data transmission technology,the packet loss rate will increase with the increase of the communication distance,which directly leads to low data transmission efficiency.For this reason,research on data transmission technology based on LoRa is proposed.First of all,on the basis of ensuring the comprehensive coverage of LoRa technology,set up the TDMA networking protocol;secondly,in order to promote the normal operation of data transmission under low power consumption,choose the LoRa modem based on the chip SX1276 and determine the relevant parameters;Finally,through the application program The function realizes the efficient transmission of data under LoRa technology.According to the comparison results of the simulation experiment,under the premise that the transmission distance is 5000 and the number of packets sent is 2000,the data transmission technology based on LoRa has the lowest packet loss rate,which is only 4.7%.
