Highway Tunnel IP Network Broadcast Intercom System Solution

High-speed Road and Tunnel IP Network Broadcast Intercom System Solution

1. Introduction of IP network broadcast intercom system for highways and tunnels

The IP broadcast command and dispatch system for expressways and tunnels is an integrated solution for IP network voice transmissions that we need to design according to the needs of modern highway management centers to command and manage highway toll stations and service areas.

Highway and tunnel IP broadcast command and dispatch system, based on TCP/IP network communication protocol and digital audio technology, digitizes and samples the audio signal of the initiator of the communication, and then transmits it to the receiver in LAN and WAN in the form of data packets. End-to-end decoding into audio signals. According to the application requirements and usage scenarios of the expressway, the system implements information broadcasting, two-way calling, multi-party calls, and forced call paging for the service of each toll station in the management center, and can perform emergency broadcasting in emergency situations (such as fire). Notice, can play background music, etc. when idle.

2, system characteristics

● The use of the original computer network, without rewiring, only need to set up an audio line inside the broadcasting point, and use digital transmission between each point for several hundred kilometers to realize remote broadcasting;

● Realize fixed-point, partition, and broadcast speeches through program control;

● The background music is played in a regular time zone and is unattended. The system automatically sets the power point of the power amplifier.
