Project Overview:
Tunnel emergency network broadcasting system: There are multiple tunnel points, each of which needs to achieve independent broadcasting and paging, and can also communicate with the management center or receive paging and broadcasting from the management center< Br/> The intercom terminal can have two-way intercom with the control room or other intercom terminals. The network audio column can be controlled by the control room to broadcast or page. When there is an emergency, the button can be pressed to give an emergency sound and light alarm (the sound and light alarm flashes and alarms)< Br/> Design this broadcasting system according to the needs of modern highway section management center for commanding and managing highway tunnel points. This broadcasting system is a digital broadcasting system that operates on an Ethernet system as a platform to achieve full digital audio lossless transmission. In an environment with network conditions, it is easy and fast to establish an advanced digital broadcasting system without the need for dedicated audio and control buses. This system has strong scalability, saves construction costs for system installation, protects the aesthetics of existing buildings, and provides convenience for future maintenance and management< Br/> This system is mainly applied to highways, and the management center conducts business information broadcasting, full duplex two-way calls, multi-party calls, and mandatory answering and paging for various tunnel points. In case of emergency situations (such as fires), emergency broadcasting notifications can be provided, and background music can be played during idle time. To improve the service quality of highways and facilitate work management, we provide high-tech digital equipment solutions< Br/> Project requirements:
The design of the public address system is mainly aimed at providing emergency voice information to vehicles in the tunnel through the network broadcast system in case of emergency situations. At the same time, modern audio transmission, promotion, and activities are improved to carry out digital information dissemination. At the same time, clear and stable background music system support is also provided for the activities. The specific requirements are as follows:
The intercom terminal can have two-way intercom with the control room or other intercom terminals, the network audio column can be controlled by the control room for broadcasting or paging, and when there is an emergency, the button can be pressed to give an emergency sound and light alarm (the sound and light alarm flashes and alarms). By using the IP network, the broadcast audio terminals, network paging stations, and sub control software operating systems in various regions are connected to form a digital network broadcasting system for unified management< Br/> Equipped with functions such as manual broadcasting, scheduled broadcasting, temporary insertion, terminal configuration, terminal status viewing, terminal work monitoring, and program library establishment, as well as supporting external functions such as fire linkage broadcasting and wireless remote control broadcasting; The system supports terminal remote on-demand, paging terminal intercom and broadcasting functions< Br/> The audio is diversified, and various self-made voice programs (such as promotions, introductions, notifications, etc.) can also be uploaded to the server and automatically played on time or for terminal demand. The control points can submit scheduled playback tasks through workstation software, and arrange voice playback plans and promotional themes for areas within their jurisdiction, creating a good atmosphere< Br/> Leaders do not need to go to the computer room to publish broadcast management information for each point in their own office< Br/> Broadcasting equipment
