Underground pipe gallery emergency intercom telephone and broadcasting system

I. Solution Introduction

1, system architecture

Combined with the current technological development and management requirements of underground corridors, a set of professional multimedia intercom broadcasts are designed for underground corridors that integrates wired emergency intercom, radio shouting, emergency broadcasting, dispatch management, video linkage, office communication, and external network interworking. Scheduling management system, the system can be deeply integrated with other systems for application management, improve the information management level of the corridor, effectively reduce the cost of enterprise operation and management, and improve daily work efficiency and emergency handling capabilities.

The system is mainly composed of a monitoring center part, a communication transmission part, a front-end emergency intercom part, and a front-end emergency broadcast part. The system equipment and function modular design can be flexibly selected to increase, decrease, or expand.

The front-end communication hosts are connected by 1-core optical fiber before and after. Each tube gallery, such as the integrated warehouse and power warehouse, forms a communication transmission ring network. It is recommended that one communication ring network be set for each 32 front-end communication hosts, and one for every three corridor rooms. Front-end communication host, a single communication ring network can cover the transmission of 96 warehouses

The front-end communication host and the front-end communication extension can be connected with a 2-core telephone line, and the distance can be transmitted up to 400 meters. The front-end communication host and the horn speaker can be connected with a 2-core cable, and the distance can be transmitted up to 300 meters.

- Emergency talk section

A front-end communication host is installed in every 3 corridors. Each front-end communication host has a built-in emergency intercom access module, which can support the access of up to 8 front-end communication extensions.

The communication line is directly powered, and the installation is simple and convenient. The front-end communication host can automatically call the monitoring center after 3 seconds of off-hook, and can manually dial out to achieve selective calling within 3 seconds. Calls between front-end communication extensions or dialing outside numbers, etc.

- Emergency broadcast part

A front-end communication host is installed in every 3 corridors. Each front-end communication host can be equipped with a built-in emergency broadcast power amplifier module, which can support the access of 10 10W horn speakers. Two can be installed in each warehouse, which can cover 3 Emergency broadcasts in warehouses or aisles. The communication line is directly powered, and the installation is simple and convenient. You can set timed broadcasts, temporary broadcasts, safety reminders, broadcast shouts, district shouts, etc. through the center.
