Port
Paging, Intercom, and Emergency Communication System for Ningbo Zhenhai Port
| Requirement Category | Specific Requirement |
|---|---|
| Full-Area Coverage | Enable blind-spot-free voice coverage across terminals, yards, tank farms, waterways, and all other areas, while supporting interconnection among handheld terminals, fixed telephones, and paging loudspeakers, with multiple teams online at the same time |
| Emergency Linkage | Deeply integrate with fire alarms, environmental monitoring systems (gas / liquid level / temperature), video surveillance, and emergency shutdown systems in tank farm areas, so that emergency procedures can be automatically initiated after an alarm is triggered |
| Multi-Network Integration | Compatible with maritime VHF, carrier 4G/5G, and industrial ring networks, supporting cross-system communication among port authorities, maritime agencies, fire services, emergency management departments, and other parties |
| Environmental Adaptability | Equipment must meet a protection rating of IP66 or above, with resistance to salt spray, vibration, and interference, and support 72 hours of emergency power supply after power failure |
| Audio and Video Dispatching | The command center can view live on-site video in real time and achieve linked voice + video dispatching, with commands delivered to the operation site within 3 seconds |
| Precise Positioning | Support real-time positioning of personnel / vehicles / key equipment, quickly identifying incident points and trapped personnel to reduce rescue time |
| Layer | Core Equipment | Function Description |
|---|---|---|
| Control Center Layer | Becke IP paging intercom core server (BK-RCS-U4000), touchscreen dispatch console (DSC-BD215S-IP), integrated video platform (BK-DVG108032P) | Acts as the system control hub, enabling unified command, device management, multi-system linkage, and audio-video dispatching |
| Transmission Network Layer | Industrial-grade fiber optic ring network, 5G private network base stations, Mesh self-organizing network gateways | Builds dual-redundant transmission links (fiber as the primary network, 5G/Mesh as backup), with short self-healing time to ensure uninterrupted signals |
| Field Terminal Layer | Explosion-proof emergency help phones (EX-BT27/EX-BH621), SIP paging loudspeakers (SK Series), audio-video alarm devices (AL-200), handheld intercom terminals | Deployed across all areas to perform one-touch alarms, two-way intercom, and zoned broadcasting commands, enabling real-time communication between the field and the center |
| Linked Control Layer | Fire interface modules, environmental monitoring terminals, tank farm control units, video access gateways | Automatically triggers emergency events and links equipment such as fans, lighting, and isolation doors, reducing manual intervention and improving response efficiency |
The backbone network uses an industrial fiber optic ring network with a dual-ring redundant design and short self-healing time to ensure stable terminal transmission;
Private network base stations are deployed in operation areas, and full-area coverage is achieved through a distributed antenna system (DAS), solving signal attenuation in open areas;
Mesh self-organizing network gateways are deployed in key areas such as tank farms and waterways, enabling one-touch networking and automatic switchover in the event of a primary network failure to ensure 72 hours of uninterrupted emergency communication.
Environmental monitoring / fire alarms automatically trigger a full emergency response process:
The center pushes alarm information (location + type);
On-site audio-video alarms + emergency broadcasting guide personnel evacuation;
Fans, emergency shut-off valves, and emergency lighting are activated in linkage, while isolation doors are closed;
Information is simultaneously shared with maritime authorities, fire services, and other departments to support cross-department coordinated response.
