Faced with challenges such as single water conservancy supervision methods and inadequate mobile public network coverage in ecological water areas in China, the integration of Beidou short message communication technology and digital information collection technology enables automatic hydrological measurement and reporting. This significantly enhances the capabilities of water conservancy and hydrological monitoring, query, early warning, and emergency response.
In severe weather or special disaster environments, Beidou satellites provide 24/7 seamless automatic monitoring, including real-time deformation monitoring and hydrological regime monitoring. This allows for early warnings and personnel evacuation, gaining valuable time for rescue operations. The backup communication channel of Beidou satellites ensures the timely transmission of hydrological information, providing a solid guarantee for the reliability of hydrological data during critical flood control periods. It effectively addresses the monitoring blind spots caused by the inability to conduct manual monitoring under special disaster weather conditions.
The Beidou-3 Short Message Terminal, integrated into hydrological and rainfall monitoring systems, enables unmanned and autonomous monitoring of ecological water conservancy. By real-time collecting, transmitting, and processing water conservancy monitoring data, it effectively enhances the emergency response capability for sudden incidents such as special disasters.
Additionally, it supports real-time monitoring and query of critical data including rainfall, water levels, and information technology parameters of reservoirs. During flood control periods, it assists in scientific and precise command. Increasing investment in technological innovation and development, as well as the promotion and application of scientific and technological achievements, will boost the rapid development of large-scale Beidou applications.
Advanced equipment is utilized to monitor dynamic changes at various hydrological/rainfall monitoring points of reservoirs and flash flood disaster prevention points, deriving relevant parameters for analysis and early warning. Among the key devices, Beidou-3 data transmission terminals, Beidou communication command receivers, and integrated communication RTUs are widely adopted in water conservancy and hydrological monitoring.
There are two data collection methods: one is the combination of remote terminal units (RTUs) and Beidou data transmission terminals; the other is the use of integrated communication terminals. Equipped with two data transmission links—Beidou short message service (SMS) and mobile communication networks—these integrated communication terminals are managed through the intelligent water conservancy platform system, enabling the collection of diverse ecological and water conservancy data.
The Beidou short message function supports two-way communication. As long as within the service coverage, "short messages" can be sent to Beidou satellites.
The Beidou-3 Short Message Terminal is a short-message communication technology based on the Beidou Satellite System, featuring advantages such as fast information transmission, wide coverage, and high reliability. In water conservancy and hydrological monitoring, the Beidou-3 Short Message Terminal can be applied in the following aspects:
Water Level Monitoring: By transmitting water level data via Beidou short message service, real-time monitoring of water level changes in reservoirs, rivers, and other water bodies can be achieved. This enables timely early warnings for excessive water levels, safeguarding people's lives and property.
Beidou short message service can be used to transmit rainfall data, enabling real-time monitoring and early warning of rainfall amounts. This provides a scientific basis for flood control and drought relief.
By transmitting water storage data via Beidou short message service, real-time monitoring of water storage facilities such as reservoirs and sluices can be achieved. This offers a scientific basis for water resources management.
