Hilly and mountainous areas in China cover an extremely vast area with complex and changeable terrain, leading to frequent flash flood disasters. This situation poses an extremely serious threat to the lives and property safety of the general public.
To effectively address this severe challenge, improve the transmission speed and coverage of flash flood disaster early warning information, and ensure that early warning information can be transmitted to every potentially affected area and individual in a timely and accurate manner, it is noted that most of the early-stage broadcast equipment relies on 2G networks. The 2G network mainly supports voice calls and short messages, with a low data transmission rate.
The 14th Five-Year Plan for the Development of the Information and Communications Industry clearly requires accelerating the decommissioning of 2G/3G networks and optimizing the allocation of spectrum resources. Therefore, it is decided to fully upgrade the existing 2G wireless early warning broadcast system. The plan is to update it to a more advanced 4G/5G network broadcast system with faster transmission speed and wider coverage, so as to minimize losses and protect the lives and property of the people when flash flood disasters occur.
II. Upgrade Objectives
The iteration of 2G technology has rendered the earlier early warning broadcast equipment unable to connect to the network and function normally. However, the upgrade from 2G to 4G/5G is an inevitable choice driven by technological iteration and policies. Through spectrum refarming, user migration and infrastructure upgrading, outdated capacity will be phased out, and resources will be released to support the development of the digital economy.
Improve the transmission speed and stability of early warning information to ensure that it is delivered to affected areas in a timely and accurate manner.
Expand the coverage of early warning information to achieve the release of such information within a wider range.
Enhance the reliability and usability of the system, and reduce maintenance costs.
The upgrade from 2G to 4G/5G is driven by technological iteration and policies, but it also brings challenges such as broadcast equipment costs, coverage, and user adaptation. Against this background, Chenmai Wisdom has customized and developed an intelligent broadcast terminal to address the issues of cost, coverage, and adaptability faced by users.
The intelligent broadcast terminal achieves voice connection with the audio port of the old broadcast equipment via its own audio port. This enables the network upgrade of on-site broadcasts without changing the existing environment, realizing the technical transition from 2G network to 4G/5G network.
█ Text is sent through the Chenmai Intelligent Operation and Maintenance Platform/App. The terminal converts the text to speech and outputs it through the audio port to realize broadcasting;
█ Make a call to the terminal. The call voice is output through the audio port to realize broadcasting;
█ Send the broadcast content to the terminal via SMS. The terminal converts the broadcast content to speech and outputs it through the audio port to realize broadcasting.
The Intelligent Telemetry Terminal is a customized device developed by Chenmai Wisdom for the technological iteration and upgrade of early warning broadcast equipment from 2G networks to 4G/5G networks. It features simple and convenient installation, and can solve the problems of cost, coverage and adaptability faced by users.
Its main functions are as follows:
█ Equipped with an audio port; it can realize voice connection with the audio port of existing broadcast equipment to achieve broadcasting;
█ Supports answering calls and outputs the call through the audio port to achieve broadcasting;
█ Supports SMS reception, converts SMS content into voice, and outputs it through the audio port to achieve broadcasting;
█ Supports receiving text sent by Chenmai Wisdom's operation and maintenance platform, converts the text to voice, and outputs it through the audio port to achieve broadcasting;
█ Supports remote setting and remote upgrade;
█ Supports reporting working condition information to the operation and maintenance platform;
█ Supports the networks of the three major telecom operators.
Chenmai Wisdom Integrated IoT Platform is a comprehensive Internet of Things (IoT) platform that integrates device management, data monitoring, operation and maintenance management, and alarm management. This platform aims to help enterprises efficiently manage IoT devices, monitor device status in real time, optimize operation and maintenance processes, improve device management efficiency, and reduce operating costs.
The intelligent broadcast terminal can be managed and maintained on the intelligent operation and maintenance platform through the following functions:
█ Supervision of terminal working condition information and upgrade maintenance of devices;
█ Distribution of early warning broadcast content, enabling group-based distribution;
█ Voice capture via mobile app, conversion to text, and distribution of broadcast content.
Through the specific implementation and advancement of the above-mentioned plan, we will be able to smoothly and effectively carry out a comprehensive upgrade of the 2G wireless early warning broadcast systems currently still in use, transforming them into more advanced and efficient 4G/5G network broadcast systems.
This upgrade measure will not only significantly improve the transmission speed and timeliness of flash flood disaster early warning information, ensuring that the early warning information can be quickly delivered to relevant areas in the first place, but also greatly expand the coverage of early warning information, enabling more residents to receive key disaster prevention and mitigation information in a timely manner.
In this way, we can provide more solid and powerful protection for the life safety and property safety of the general public, effectively reduce the potential risks and losses caused by flash flood disasters, and further enhance the overall disaster prevention and resistance capacity of society.
