Abstract In order to solve the problem of low data reporting rate of single GPRS data upload channel of unmanned island automatic weather station in Nansha District of Hainan Province,this paper makes use of the advantages of Beidou satellite communication.Firstly,the communication terminal based on Beidou satellite and the supporting power supply system are added to the hardware to realize the dual channel parallel operation of GPRS and Beidou communication at island station.Secondly,each channel is defined as a logical site,two logical sites form an observation system,upload a data packet,and realize the localization application of the observation data through the local terminal.This paper also analyzes the data arrival rate before and after the transformation,and the conclusions can further improve the level of disaster prevention and mitigation on the island.

Key words： Beidou communication island automatic weather station logical site data arrival rate
