WEP5500 Cloud Broadcast Solution for Emergency System

Cloud Broadcast Solution for Emergency System

Solution Overview

The Emergency Broadcast System is an important part of the construction of the radio, film and television public service system, and plays an important role in public opinion guidance, instruction transmission, information release and emergency broadcasting. In order to meet the needs of the National Public Emergency Warning Information and the construction of the National Emergency Broadcast System, it is necessary to improve the corresponding functions. And the Emergency Broadcast System should carry the information release and dissemination capabilities of the people's governments at all levels in the response to natural disasters, accidents, public health and social security and other public emergencies, so as to ensure the safety of the people's property to the greatest extent.

Design Target

● Improve Broadcast Coverage: Ensure that large areas such as parks and villages can achieve stable broadcast coverage without dead ends.

● Real-time Broadcasting: Through the Cloud Broadcast System, broadcast information can be released at any time, especially when emergencies or activities are scheduled, and information can be quickly conveyed.

● Multi-function Integration: Support voice broadcasting, background music, emergency notifications and other functions.

● Convenient management and scheduling: Through centralized management of the cloud platform, administrators can remotely control broadcast content, schedule broadcast time, monitor device status, etc.

● Cost Saving and Efficiency Improvement: Reduce the hardware investment and maintenance of the traditional cable broadcasting system, and use the existing 4G network, FM and other equipment to build and operate the system.

Demand Analysis

System Introduction:

DSPPA Cloud Broadcast System adopts full B/S architecture, and at the same time uses advanced concepts such as digital coding technology, digital decoding technology, addressable management technology, IP/RDS/4G communication technology as the technical guidance, makes full use of the existing radio and television network and IP Internet for transmission coverage, and realizes multi-level security emergency broadcasting, timing broadcasting, mobile APP mobile platform insertion, terminal addressing and volume control, GIS map monitoring and other basic functions. DSPPA Cloud Broadcast System is widely used in broadcasting systems that need to be built across regions in a unified manner, such as village response emergency broadcasting.

Demand Analysis：

Information Dissemination in Remote Areas

● In remote areas, wiring and power supply are challenging, making it difficult to reliably transmit information such as policy announcements and technological services.

Broadcast Warnings in Sensitive Zones

● Sensitive sites such as reservoirs and power stations require high security, necessitating the integration of surveillance, infrared body detection, and broadcast systems for real-time alert notifications, a capability that traditional public address systems cannot provide.

Audiovisual Distribution in Large Industrial Parks and Chain Stores

● Large industrial parks and expansive chain store networks require a unified system for managing audiovisual and multimedia content distribution, a task that traditional network PA systems often cannot handle efficiently.

FM Cloud Broadcast System for Scenic Spot

Solution Configuration Description:

● DSPPA FM Cloud Broadcast System sends the audio signal to the scenic spot in the form of data packets, and the RDS codec function of the broadcast control host can convert the broadcast signal into RDS signal, modulate and amplify it through the FM transmitter, and send it to each broadcast point in a wireless way to solve the coverage problem of the last kilometer of broadcasting

● Emergency Audio Decoder WEP5528TS：Integrating a variety of broadcasting, control, communication and security functions, scenic staff can upload, edit and schedule broadcast content according to their needs, and issue announcements in real time.

● 200W Wireless PA System Transmitter WEP9200T: Make sure the FM signal covers the entire scenic area. It can be selected and laid out according to the scale and actual situation of the scenic spot to ensure that the FM signal has no dead ends.

Note: The terminal can be adjusted according to the actual application scenarios. This system solution is for reference only. Please contact us if needed.

4G/IP Cloud Broadcast System for Park

Self-built server: Purchasing the platform software includes one server with a capacity of up to 100 devices. If exceeding 100 devices, it is recommended that customers purchase a standard server (such as DELL R740).

Solution Configuration Description:

● It adopts DSPPA 4G Cloud Broadcast System, including WEP5528TS Emergency Audio Decoder, WEP5500 Wireless Public Address Platform, WEP5530 Emergency Paging Station, WEP253RPG Emergency Receiving Multi-Mode Terminal, WEP6026RPG Emergency Receiving Multi-Mode Column Speaker.

● With the WEP5500 Wireless Public Address platform as the core, it supports remote management of B/S architecture and realizes unified cross-regional management and control through 4G/5G networks. The platform integrates GIS map function, which can view the distribution and status of broadcasting terminals in real time, and supports multi-level authority allocation (such as general control center, sub-control station, and patrol personnel);

● The 4G/5G network is used as the main transmission channel, combined with optical fiber or Wi-Fi to cover key areas (such as visitor centers and main roads), and the IP wired terminal is configured to transmit audio signals in the form of data packets on the LAN or WAN. The configuration of 4G wireless terminal uses 4G mobile phone traffic card for networking, which is easy to maintain and saves a lot of wiring

● The terminal WEP253RPG and WEP6026RPG are powered by solar energy, which eliminates redundant wiring, saves energy, and realizes green and sustainable development.

Note: The terminal can be adjusted according to the actual application scenarios. This system solution is for reference only. Please contact us if needed.
