Communication Solutions for Tunnels

Key Features & Capabilities

• Integrated Emergency Systems: The J&R broadcasting system can be organically combined with the emergency telephone system, using the same console, signaling system, and communication cable to achieve unified control of both systems for enhanced operational efficiency.
• Near-End Amplification Technology: The power amplification of this broadcast system uses near-end amplification, which is a significant feature that enables transmission and control through the access network, truly realizing remote operation of the broadcast system.
• Intelligent Caller Control: The system adopts caller control functionality. After the console broadcast is released, the system can automatically enter the standby working state to reduce energy consumption and optimize power efficiency.
• Program-Controlled Broadcasting: The broadcasting system can program-control fixed-point, fixed-film, and full-line calls with clear and loud voice during broadcasting, ensuring no feedback howling for optimal audio quality.
• Simple Operation Interface: This broadcasting system is simple to operate with the system host and emergency telephone system integrated into a main control machine. When the broadcast system needs to work, only simple operations are required on the main control machine.
• Flexible Broadcasting Options: A microphone or a duty telephone can be used for broadcasting, providing operational flexibility for different emergency scenarios and routine communication needs.
• Emergency Response Integration: Seamless integration between emergency telephone calls and broadcasting capabilities allows for immediate response and evacuation coordination during tunnel emergencies.
• Cost-Effective Design: The unified system approach simplifies infrastructure requirements and saves investment costs while maintaining high performance and reliability standards.
• Enhanced Monitoring Efficiency: Unified control systems effectively improve the work efficiency of tunnel monitoring rooms and management offices through streamlined operations and centralized control.
• Underground Environment Optimization: All communication equipment specifically designed for underground tunnel environments with considerations for humidity, limited ventilation, and unique acoustic challenges.
• Real-Time Emergency Communication: Instant communication capabilities between tunnel users and management centers, enabling rapid response to incidents, breakdowns, and emergency situations.
• Multi-Zone Broadcasting: Capability to broadcast to specific tunnel zones, entire tunnel sections, or multiple tunnels simultaneously depending on the nature and scope of the emergency or information being communicated.
• Backup Power Systems: Comprehensive backup power solutions to ensure communication systems remain operational during power outages or emergency situations when reliable communication is most critical.
• Integration with Traffic Management: Seamless integration with tunnel traffic management systems, ventilation controls, and fire safety systems for comprehensive tunnel safety management.
• Maintenance and Monitoring: Built-in diagnostic and monitoring capabilities for proactive maintenance scheduling and real-time system health monitoring to ensure continuous reliable operation.
