Coastal Radio Station Emergency Communication System Plan
Release date:
2026-05-19
As global climate change intensifies and extreme weather events become more frequent, the risk of natural disasters in coastal regions is steadily increasing, making maritime operational safety and emergency communications a growing societal priority. Coastal radio stations, serving as the central hub of maritime communications, perform critical functions such as distress alerting, dissemination of safety information, and routine communication coordination; their emergency communication capabilities directly impact the safety of lives at sea and the protection of property. However, traditional coastal radio systems often experience communication disruptions during large-scale disasters due to aging equipment, limited coverage, and insufficient disaster‑resilience, leaving them unable to meet the demands of modern emergency management. Consequently, developing an efficient, reliable, intelligent, and multi‑modal integrated coastal radio emergency communication system has become an urgent task for enhancing maritime emergency response capabilities. This paper systematically outlines the design rationale, technical architecture, and implementation roadmap of this solution, offering guidance for building robust emergency communication infrastructure in coastal areas.
Plan Description:
To ensure the smooth and reliable operation of communication services, coastal radio stations employ 2 Mbit/s digital transmission channels—such as digital microwave systems and optical transceivers—and utilize PCM access equipment to multiplex services onto these 2 Mbit/s channels. Coupled with 2 Mbit/s channel automatic switchover devices that operate without signal degradation, this approach significantly enhances the security and reliability of channel transmission.
The entire system ensures that all critical services remain uninterrupted over the 2M digital channel, with seamless automatic switchover to the backup transmission path in the event of a primary route failure. The proposed solution leverages PCM equipment to interface with various types of service data, and, to guarantee the security and reliability of the E1 (2M) lines, Guangzhou YinXun also deploys E1 protection‑switching devices to implement primary‑backup protection for these circuits.
When the primary E1 line fails, the system seamlessly and without any service interruption automatically switches over to the backup E1 line. Once the primary E1 line is restored, the system automatically switches back to it, fully meeting the customer’s requirements for critical departments.
1. Link Channel: The customer must provide one primary and one backup E1 (2M) channel.
2. Recommended equipment: Central Office: ZMUX-3300
Remote: ZMUX-122, ZMUX-30
