Before the end of next year, Chengdu will create a virtual "arteries"

recently

Xiaobu learned from Chengdu Water Affairs Bureau

Relying on "Smart Rongcheng" digital base

Before the end of 2023

Chengdu will build the Jinjiang River Basin and Minjiang River Basin

Digital twin base

What role will its completion play?

May wish to learn from Xiaobu

In layman's terms, the digital virtual version of the Jinjiang River Basin and the Minjiang River Basin, just like outside the human body, a holographic projection generally creates a virtual "arteries". This virtual "arteries" can not only show the situation of Jinjiang in real time, but also dynamically simulate the situation after the flood situation, help the daily supervision of the river and the flood prevention.

Smart Water Comprehensive Management Platform

Behind the virtual "arteries"

More than 140,000 pairs of "eyes"

In the office of the flood and drought resistance command of the Chengdu Water Affairs Bureau in Shujin Road, Chengdu, you can see a large screen covered with the entire wall. Through this large screen, you can know that there are various types of information related to the water related to the water without walking out of the office, including real -time rain, rivers floods, urban waterlogging points, flood disasters, river reservoirs, etc. Behind this screen is one of the eight major scenes of "Smart Rongcheng". The staff of the Chengdu Water Affairs Bureau light up the screen. It can be seen that the integrated smart water management platform includes 12 functional modules such as water resources management, river length system, water supply management, drainage management, flood prevention and disaster reduction, and Tianfu Blue Network.

Real -time rain

Click on flood prevention and disaster reduction to enter the Chengdu Flood Control Command System. Not only can you see the distribution of rainfall here, the situation of reservoir, river channels, and piercing tunnels is also clear at a glance: Under the framework of Smart Rongcheng, the flood prevention safety situation in Chengdu has a clear outline. The relevant person in charge of the Chengdu Water Affairs Bureau said: "If you only rely on the staff to go to the scene to understand and deal with the situation, the workload is large and the efficiency is not high, especially the extreme weather in the flood season."

The goal of smart water construction is first of all "one -screen view." All this is inseparable from a unified data resource system. "Relying on the digital base of Smart Rongcheng, the system brings together the water -related data from various departments such as the ecological environment, public security, hydrology, and meteorology. Key data of water resources. For example, there are 137 water quality monitoring stations, more than 140,000 video stations, 180 water level flow stations, 253 reservoir water level stations, 938 rainfall stations, 43 underneath tunnel monitoring stations, and 222 pipeline monitoring stations.

Forecasting

It is worth mentioning that it is precisely that with these data support that the digital twin Twin River Chengdu Jinjiang section has been included in the Ministry of Water Resources to trial construction first. The "Digital Twenty -Di River Basin Chengdu Jinjiang Section first trial implementation plan" has passed the review of the Ministry of Water Resources and the Yangtze River Commission experts. It will focus on the construction of the digital twin application scenarios in the basin. By the end of 2023, Chengdu will build a digital twin base in the Jinjiang River Basin and the Minjiang River Basin. "Not only can restore the Jinjiang River, but more importantly, based on a large number of outer perception equipment, which can simulate the flowing water in real time." The relevant person in charge of the Chengdu Water Affairs Bureau said that if the river in the city is compared to the human arteries, the digital twin base Just like a "virtual artery" outside the human body. The river channels thousands of miles away seemed to be in front of them, including the rise of the river water clearly, and even predict the future trend.

The system is in the learning stage

It is expected to predict the waterlogging point in the future

Flood prevention work is "prevention". "With the continuous improvement of the digital base of Smart Rongcheng, Chengdu's flood control system is becoming more and more intelligent, accurate, and efficient." The relevant person in charge of the Chengdu Water Affairs Bureau said that the flood control command system has integrated the monitoring data of hydrology, weather, public security and other departments. And the monitoring site information of the Provincial Water Resources Department, Aba Prefecture in the upper reaches of the Minjiang River, and Deyang City, the upper reaches of Minjiang River.

Once more than 50 millimeters of heavy rainfall or super police water level occur, the system will be warned in different colors in the list. The flashing data here is the limited water level in the water level of the reservoir. At present, the system can monitor online 237 reservoirs in real time in real time. The video on both sides shows the real -time monitoring of the reservoir. At the same time, the system will launch a flood prevention emergency plan in a timely manner according to the warning situation and weather trends and send SMS notifications such as emergency and urban management through the system.

Sunde Meiyu and River Long System E Platform

In response to the main types of flood disasters, the system builds a picture of rivers and rivers, a picture of urban waterlogging, and a picture of a flood disaster. Monitoring, rainfall and other more than 10 thematic layers, meteorological radar, real -time rain, reservoir water conditions, and river water conditions. The system has digitized all engineering information and responsible persons to provide data support for command scheduling. At the same time, the system can automatically associate the surrounding videos according to the site location, and master the situation at the first time. "In order to achieve disaster forecasting and forecast, we have initially built a hydrological model, Nanhe hydrological model, 1 × 1 km grid -based rainfall forecast model, a waterlogging model in the central city, and put into trial operation." The person in charge said that the system is currently still the system. In the learning stage, such as the waterlogging model in the central city.
