Caltta Helps Yongding River Build Emergency Communication Network

Project Background

In July 2023, affected by Typhoons "Doksuri" and "Kanun," the Beijing-Tianjin-Hebei region experienced an unprecedented heavy rainfall, resulting in severe flooding. The Ministry of Water Resources classified this flood as a "23·7" regional flood in the Haihe River Basin, the largest flood in the Yongding River since 1956.

The disaster caused "disrupted roads, power outages, and network interruptions," with traditional communication systems down. An emergency communication network was urgently needed to ensure rescue command and personnel safety. The emergency communication private network needed to be strong, durable, secure, reliable, and controllable, usable in both peacetime and wartime. Leveraging its narrowband self-organizing network's rapid deployment, stable communication, and efficient coordination capabilities, Caltta quickly built an emergency communication private network for the Yongding River.

Solution: Building a New Model for Water Conservancy Emergency Communication

Dispatch Platform Construction

Deploying a self-organizing network dispatch platform in the Yongding River Basin operational management company to enable daily communication and flood season command and dispatch.

Key Area Coverage

Deploy narrowband self-organizing network devices at hydropower stations, dams, and mountaintop locations to provide wide-area relay coverage, ensuring real-time communication and tracking during inspections.

Multi-Link Interconnection

Integrating self-organizing network + satellite + public network to ensure stable and reliable communication.

Equipment Setup

Station personnel are equipped with handheld radios for timely information exchange; self-organizing network devices are equipped with high-throughput satellite communication and mobile SIM cards to enable backup for return-link connections.

Intelligent Dispatch Management

Supports voice dispatch, location tracking, route playback, SMS sending and receiving, as well as management of terminals, groups, and network devices.

Solution Highlights: Narrowband Self-Organizing Network Solves Disaster Relief Communication Challenges

No Fear of Network Outage, Autonomous Networking

No need to rely on fixed infrastructure, multi-node self-organizing networking, quickly building an emergency communication network covering the entire area, ensuring "network down, but connection never breaks."

Ultra-Low Power Consumption, Wide Area Coverage

Narrowband transmission technology has low power consumption, with a single node covering a radius of 10-30 kilometers, achieving seamless signal extension in complex terrains, ensuring real-time interconnection between the frontline and the command center.

Strong Anti-Interference, Stable and Reliable

In harsh weather and complex electromagnetic environments, key information such as voice and location is transmitted stably, providing real-time support for disaster monitoring and personnel dispatch.

Flexible Deployment, Quick Response

The equipment is lightweight, plug-and-play, and can be delivered by drones or carried by rescue personnel, quickly establishing a network to seize the "golden rescue time."

Solution Value: Guarding Water Conservancy Safety, Supporting Smart Prevention and Control

Multi-Level Command Coordination

Breaking the information chain for reservoirs, power stations, and management companies, with commands issued in seconds, ensuring precise allocation of rescue resources.

Personnel Safety Guarantee

Providing location tracking and emergency communication, reducing the risk of secondary disasters, and protecting the safety of rescue teams and the public.

Water Conservancy Disaster Prevention Upgraded

Dual-use for peacetime and wartime, improving the resilience of water emergency communication, helping the transformation of water conservancy disaster prevention from "passive emergency response" to "active prevention and control."

As global climate change accelerates and extreme weather events occur more frequently, water conservancy safety has become a major issue concerning national and public interests. Caltta's narrowband self-organizing network technology, with its low cost, high reliability, and ease of expansion, provides an innovative solution for building an "air-ground-space integration" water monitoring network.

In the future, as a leading and professional dmr supplier, Caltta will continue to deepen the integration of narrowband self-organizing networks with artificial intelligence, BeiDou navigation, and other technologies, promoting their large-scale application in flood early warning, river and lake supervision, and ecological protection, helping the water conservancy industry achieve "forecast, early warning, simulation, and plans" full-chain intelligent management, contributing technological power to safeguard the peace of rivers and ensure the safety of people's lives and property!
