These solutions are deeply integrated and optimized for technical performance, enhancing system reliability, reducing energy consumption, and improving operational efficiency. Below is a detailed overview of each solution.

Matrix Public Addressing Solution

The Matrix Public Addressing System is designed specifically for public transportation environments, providing integrated broadcasting services including safety announcements, emergency alerts, train information, service updates, and entertainment content. This system aims to enhance the efficiency and accuracy of information delivery, offering comprehensive service to passengers.

System Features:

Safety Alerts and Warnings

The system can broadcast various safety tips and emergency warnings in real time. For example, during a fire or other emergencies, it can quickly issue alarms and provide clear evacuation instructions, significantly improving passenger safety and reducing confusion during incidents.

Train and Service Information

The system provides up-to-date train schedules and service information, ensuring passengers receive accurate arrival and departure times. This helps passengers plan their journeys better and avoids issues caused by outdated information.

Entertainment Content

To improve the travel experience, the system also offers a range of entertainment content, including music, news, and weather updates. This content helps passengers pass the time and enhances their overall travel experience.

System Highlights:

High Integration

The Matrix Broadcasting System integrates fire alarm voice announcements, digital amplifiers, paging, and alarm systems into a single device. This integrated design simplifies equipment setup and management, reducing the number of devices and maintenance efforts.

High Reliability

The system uses a decentralized architecture without a central server, avoiding single points of failure. It includes multiple reliability measures such as amplifier detection, backup amplifiers, circuit checks, power and network backups, and CPU off features to ensure stable operation under all conditions.

Distributed Architecture with Flexible Configuration

The system uses a TCP/IP network-based distributed deployment, allowing flexible expansion according to actual needs. This flexibility makes the system adaptable to various scenarios, from small stations to large transportation hubs.

Eco-Friendly and Efficient

The system uses low-loss Class D power amplifiers, reducing device count and space usage while lowering energy consumption, achieving both environmental and efficiency goals.

Surveillance Microphone (Audio Monitoring) Solution

The Surveillance Microphone (Audio Monitoring) System plays a crucial role in public transportation environments by enhancing monitoring effectiveness and response capabilities through high-definition audio capture and intelligent management. It is particularly useful for precise audio capture and analysis, boosting safety.

System Features:

High-Definition Audio Capture

The system supports high-definition audio collection, ensuring clear and complete sound quality. This is essential for accurate information retrieval and processing.

Network-Based Management

The system enables remote monitoring and management through a network platform, allowing administrators to track audio status and operate the system remotely. This approach increases monitoring efficiency and reduces reliance on manual intervention, lowering operational costs.

Key Sound Detection and Alerts

The system can detect and alert specific keywords or sounds, such as "help," "Call the Police," or other preset noises (e.g., coughing, gunshots). This feature is crucial for triggering alarms and notifying relevant personnel during emergencies, improving response capabilities.

IP Emergency Intercom Solution

The Emergency Intercom System is designed to improve the efficiency of passenger assistance in emergencies, providing two-way intercom and video call functions, and supporting command and control and safety guidance. This system plays a vital role in emergency response and daily communication.

System Features:

One-Button Emergency Call

The system supports a one-button emergency call feature, allowing passengers to quickly request help with a single press. This reduces waiting times in emergencies and speeds up assistance.

Two-Way Intercom

The system enables real-time two-way voice communication between passengers and staff, ensuring accurate information exchange and timely response, improving service quality.

Video Calling

The system supports video calls, allowing face-to-face communication between passengers and staff. Video calls help resolve issues that traditional voice intercom might struggle with, such as identifying passengers or conveying complex information.

Command and Control with Safety Guidance

The system includes command and control and safety guidance functions, effectively managing and responding to emergencies. The command function coordinates staff actions, while the safety guidance function ensures passengers evacuate safely and orderly.

System Highlights:

Advanced Audio Processing Technology

The system features advanced audio processing technology with adaptive sound field capabilities. This technology automatically adjusts volume based on the environment and suppresses background noise, ensuring clear communication.

High-Speed DSP and Low Latency

The system uses high-speed digital signal processors (DSP) for fast audio processing and near-zero latency transmission, ensuring smooth and natural voice communication, enhancing conversation quality.

Window Intercom Solution

The Window Intercom System addresses communication challenges between station staff and passengers and supports remote authorization needs. The system improves communication effectiveness and operational efficiency with its advanced design.

System Features:

High-Definition Full-Duplex Intercom

The system uses single DSP multi-channel voice technology and dynamic pickup technology to ensure clear voice reproduction. It supports calls and intercom with networked monitoring centers, facilitating remote communication.

Quick Switching of Conversation Modes

The system offers three conversation modes—quiet, standard, and noisy—allowing quick adjustment based on environmental conditions. This feature ensures effective communication in various noise levels.

Single-Terminal Line Connection Design

All connections use a single-terminal line with hidden interfaces under the desk. This design reduces the risk of wire tampering, avoids loose connections, and keeps workstation surfaces tidy and aesthetically pleasing.

System Highlights:

Single DSP Multi-Channel Voice Technology

This technology achieves true digital full-duplex communication, ensuring interference-free conversation.

Dynamic Pickup Technology

The system uses dynamic pickup technology to intelligently eliminate environmental noise, ensuring accurate voice reproduction and enhancing conversation clarity and understanding.
