Sichuan: AI "magic mirror" helps intelligent flood control "second response"

"The water depth is dangerous, please do not approach!" Recently, two fishing enthusiasts entered the waters of the Yangma River without authorization. The intelligent flood control monitoring platform in Chongzhou City, Sichuan responded "in seconds" and persuaded the fishing enthusiasts to leave in time. This was thanks to the newly invested The “magic weapon” used is the China Telecom Magic Mirror Platform. Currently, nearly 300 video sensing sources with algorithmic capabilities have been installed at important flood and drought control points in Chongzhou City, Chengdu, Sichuan, to facilitate real-time observation of river water levels and to promptly dissuade people who have entered the river to stay. More than 2,000 people have been successfully persuaded to return.

It is understood that the Magic Mirror Platform is a video capability cloud platform created by China Telecom Sichuan Company to adapt to the new characteristics of intelligent and big data-based video services. It integrates video access, transcoding, co-transfer, storage, and streaming. Core capabilities such as media and AI intelligent analysis adopt unified and open technical standards to achieve open capabilities and open applications, and can achieve functions such as safe and independent control, extensive access and convergence, strong compatibility, convenient management and maintenance, and rich solutions.

In the smart water and comprehensive management application scenarios such as "Smart Flood Control" and "Smart Rivers and Lakes" created by the Chongzhou Water Affairs Bureau, all front-end sensing source devices of the Telecom Magic Mirror Platform have intelligent functions and will collect the collected data. Uploaded to the back-end platform, AI-based video analysis technology can analyze video scenes in real time, identify personnel violations and dangerous events in important places, and issue alarms in a timely manner, turning the traditional manual monitoring system into an unattended one. The real-time early warning system greatly improves the efficiency of video surveillance and effectively ensures the safety of supervision sites.

The relevant person in charge of the Chongzhou Municipal Water Affairs Bureau said that building a "safety embankment" for flood control often requires "human defense, physical defense and technical defense". In flood control and drought relief scenarios, corresponding cameras need to be installed for real-time monitoring by staff. However, in order to achieve a response speed of seconds when an abnormality occurs, the effect of ordinary surveillance cameras and manpower is not very satisfactory. After the introduction of the Magic Mirror platform, the bottleneck was broken in terms of response speed. When a moving target enters the boundary management range of the dangerous area, the platform will start to automatically broadcast voice prompts. If the moving target ignores the cloud voice warning, the intelligent system will quickly push this prompt to the Chongzhou Water Conservancy Bureau, and the duty officer will be the first to respond. time to respond.

In addition to playing a role in flood prevention work, China Telecom's Magic Mirror platform uses functions such as photography, storage, and AI analysis to achieve all-weather, intelligent, unattended early warning in real-time intelligent monitoring of key points and monitoring of personnel violations. It can also monitor dangerous areas in various scenarios through face recognition, smoking monitoring, helmet reflective clothing monitoring, smoke and open flame monitoring, license plate recognition, real-time on-duty monitoring, etc., and respond immediately when abnormalities occur. It is reported that China Telecom has deployed and installed nearly 20,000 front-end sensing devices with AI functional analysis in Chongzhou City, and actively participates in the construction of "Smart Chengdu", including "Smart Security Community" and "Police City Linkage" pilots, etc., involving urban management and law enforcement , water affairs supervision, forest fire prevention, community management, health, fire safety and other scenarios, effectively forming a perception analysis and early warning network for urban grassroots governance.
