Research on the application of Beidou-3 short satellite message in hydrological automatic measurement and reporting systems
To ensure reliable data transmission through Beidou-3 short messages in hydrological automatic measurement and reporting systems under extreme natural disaster conditions,this study investigates the technical characteristics and transmission and reception methods of Beidou-3 short messages.Combining the application requirements of hydrological automatic measurement and reporting systems,a technical scheme for data transmission and reception using Beidou-3 short messages within the automatic measurement and reporting system is proposed.Analyzing the application features of Beidou-3 short messages,it takes commonly used hydrometeorological telemetry stations as examples to summarize the integration method of Beidou-3 communication terminals,field application environmental conditions,compliance communication protocols,and control processes,selects suitable link transmission modes and message compilation methods,and proposes a scheme using Front-end Interface Units(FIUs)to receive short messages.Additionally,it analyzes the characteristics of other data reception methods for Beidou-3 short messages.The application of Beidou-3 short messages ensures stable and reliable data transmission and reception for telemetry stations and can be widely applied in various types of hydrological automatic measurement and reporting systems as a communication channel.
