Abstract:

To ensure reliable data transmission through Beidou-3 short messages in hydrological automaticmeasurement and reporting systems under extreme natural disaster conditions，this study investigates the technicalcharacteristics and transmission and reception methods of Beidou-3 short messages. Combining the applicationrequirements of hydrological automatic measurement and reporting systems，a technical scheme for data transmissionand 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 hydrometeorologicaltelemetry stations as examples to summarize the integration method of Beidou-3 communication terminals，fieldapplication environmental conditions，compliance communication protocols，and control processes，selects suitablelink 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 forBeidou-3 short messages. The application of Beidou-3 short messages ensures stable and reliable data transmissionand reception for telemetry stations and can be widely applied in various types of hydrological automatic measurementand reporting systems as a communication channel.
