It also enables machines to take on high-risk, highly-repetitive, high-precision tasks, massively improving overall productivity and safety. The system's all-encompassing perspective allows us to exceed the limits of space, time, and representation. It equips us with new capabilities and permits us to see higher, further, and with greater accuracy.

Battling the pandemic with technology

During the coronavirus outbreak, Shenzhen harnessed AI for early detection, early reporting, early diagnosis, early isolation, and early treatment.

Experts from Peng Cheng Laboratory and Shenzhen's Center for Disease Control and Prevention built a virtual doctor for COVID-19 using a deep matching model for medical knowledge. The virtual doctor not only assisted medical staff with inquiries, but also provided clinical recommendations for medical care or diagnosis and treatment guidelines compliance. 

Shenzhen University General Hospital and Bao'an People's Hospital used AI in a range of tasks, including to identify and label pneumonia lesions in images, visually display the size and proportion of patients' lesions, generate the anatomical positioning of the lesions, distinguish the left and right lungs, and automatically output a 3D reconstruction. AI was also used to compare patients' initial diagnosis and re-examination. The visual presentation of results allowed doctors to quickly conduct qualitative analysis and give diagnoses in seconds, considerably improving diagnosis efficiency.

Digital airport delivers first-class experience

To transition from paper boarding passes to a facial recognition system, Shenzhen Airport collaborated with Huawei and the Shenzhen Civil Aviation Administration to plan and roll out nearly 100 smart projects. The new system has reduced the number of delays and improved flight punctuality.

The intelligent large-scale operations and control system based on airport collaborative operations (A-CDM) and an intelligent operations center (IOC) built by Shenzhen Airport has helped it implement global situational awareness, prediction and early warnings, coordinated operations, and intelligent decision-making, greatly shortening flight transit time. 

Shenzhen Airport also launched a high-intelligence guaranteed flight phases acquisition system that uses IoT and intelligent video analysis to collect data on on-the-ground assured critical flight phases, with an accuracy rate of 95 percent. By monitoring the whole flight guarantee process, anomalous conditions in guaranteed phases that may affect clearance delivery can be rapidly discovered and solutions coordinated, which has improved on-time performance. 

Shenzhen Airport is also the first airport in China to introduce AI algorithms into its intelligent terminal stands allocation system enabling automatic and intelligent allocation of terminal stands. Now the airport can complete the allocation process for the more than 1,000 daily flights in a minute; before it used to take four hours. The system can also be refreshed every 10 minutes. The new solution has improved contact stand rate and passenger boarding bridge turnaround time at the airport.

Intelligent transportation guarantees a smooth ride around the city

Shenzhen has 3.35 million motor vehicles, equivalent to 510 cars per kilometer, the highest vehicle density in the country. This used to be the cause of significant conflict between pedestrians, cars, and roads. To solve the issue, Shenzhen Traffic Police (STP) adopted AI and 5G technology in various aspects of traffic law enforcement, congestion reduction measures, and control and command.

Working with Huawei Cloud, STP constructed a unified, citywide intelligent traffic lights control network. The traffic light timing solution powered by AI, big data, and other technologies has slashed average wait time at key intersections by 17.7 percent and boosted traffic capacity by 10 percent. The system also allows emergency vehicles such as ambulances to encounter only green lights on the way to their destination. 

AI is also used to assist law enforcement. A decision-making platform can respond in seconds to data from automatic vehicle identification checkpoints, while a secondary AI-based recognition system is used to identify unique features of vehicles, increasing the recognition efficiency of traffic infringement images by 10 times, ensuring closed-loop processing of these images.

Weather predictions are spot on with intelligent detection

The Shenzhen Meteorological Bureau (SMB) and Huawei inked a cooperation framework agreement to build a comprehensive Weather + Cloud + AI + 5G cooperation model, leveraging cloud computing, AI, 5G, and IoT. The model has helped SMB launch an intelligent grid-based precise forecasting service for the mega city and realize the cross-generational upgrade of weather services. 

The solution uses advanced technologies, such as 5G and edge computing, to improve the frequency and accuracy of meteorological observation collection. Images collected by cameras are pieced together to generate a complete picture of clouds in the sky, which can be used for grid-based accurate weather prediction.

Machine vision is used for the automatic observation of clouds and rain.  The solution can observe just 0.2 mm of light rain, which offers faster, more accurate, and more frequent observation compared to manual methods.

Finally, the solution leverages AI for the precise short-range prediction of rainfall. AI algorithms build a spatio-temporal convolutional recursive network to capture the dynamics of cloud clusters and then predicts future trends in radar echoes based on mass historical data. It provides powerful assistance for manual forecasting and can significantly improve forecasting for short-range rainfall compared with conventional optical flow.

Intelligent inspection safeguards reliable power consumption

In partnership with Huawei, Shenzhen Power Supply Bureau set up a joint innovation lab to build an intelligent power inspection solution. The solution uses machine vision with Internet-connected monitoring cameras on power transmission towers and drones to identify five typical potentially hazardous scenarios and seven major defects in transmission lines. The solution has increased inspection efficiency by dozens of times, and can also quickly discover hidden hazards that are not easy to detect using conventional manual ground inspections. The solution can detect faults and hazards in real time and perform predictive maintenance, dramatically improving the reliability of the power grid and guaranteeing the power demands of Shenzhen residents.

Intelligence speeds up government administration

The management services command center built by Shenzhen Government and Huawei is the operational and command hub of the smart city. Opening up massive amounts of data and systems, it forms a three-level subdistrict-district-city command system. Full visualization of relevant information and coordinated operations across a single network makes data-driven city management services more precise, scientific, and intelligent. This has helped Shenzhen continue to top the tables in terms of online government services in China.

In Longgang District, Shenzhen, Huawei and its partners helped the government integrate the service systems of 89 departments. In total, the government aggregated a dataset of more than 3.7 billion rows. The city's IOC has five capabilities: data center, operations center, monitoring center, distribution center, and command center. So far, 2,534 items of structured service data have been fed into Longgang District's big data platform. The total volume of data exceeds 3.7 billion rows and measures 2.7 TB. This will serve as a solid and powerful "foundation" for government data. AI-powered intelligent customer service, pre-check, and form-filling has cut down user wait time by 50 percent by increasing the handling rate by 29 percent and the pre-registration rate by 22 percent.

Smart policing ensures the city's safety

Through fund planning, platform construction, data management, and application integration, the Technology and Information Committee and Intelligence Committee of Shenzhen Municipal Public Security Bureau (SMPSB) has integrated more than 100 of their systems into six core platforms, cleaned and added 150 billion rows of data to the database, and standardized the acquisition standards. 

This has helped SMPSB achieved its goals to acquire data through police work and apply that data and share data across the entire police force. A network of cameras with AI-powered facial/license plate recognition, intelligent video retrieval, trajectory analysis, and gesture recognition form a system that incorporates multiple investigation technologies in one, helping support crime fighting and a grassroots governance model with Shenzhen characteristics.

In Bao'an District, China Telecom and the district's public security sub-bureau conducted a smart police station application scenario test at Tangtou Police Station. The solution comprised 5G, intelligent law enforcement devices, real-time HD video backhaul, and AI intelligent recognition. It enabled multi-dimensional police patrols consisting of automatic police drone patrols, police motorcycle patrols, an officer-based intelligent law enforcement system (with AR glasses and law enforcement recording device), and visualized emergency command. The technologies have helped continuously improve the effectiveness of policing and are being used to build a multi-dimensional law enforcement system for 5G scenarios and a 5G multi-dimensional police station.

Smart risk control supports worry-free spending

To become a financial center, ensuring a safe financial environment is key. To guard against financial risks, China Merchants Bank, which was established in Shekou, Shenzhen in 1987, has for many years used a smart risk control system built on big data risk control and AI for its credit cards to keep the rate of non-performing debt low.

China Merchants Bank recently upgraded its credit card smart risk control system with a transaction + behavior risk management solution that leverages AI for during-event risk management intervention. It boasts millisecond-level calculation of more than 100 million data points every day, and has cumulatively prevented billions of yuan in risk losses.

Intelligence makes the water safer

Huawei, Shenzhen Ecology and Environment Bureau, Guangming Administration Bureau, and Guangming District Water Affairs Bureau collaborated to build an intelligent water integrated management and control platform. The solution adopts big data, cloud computing, and other ICT to support decision-making for environmental water affairs. The platform's functions include comprehensive data perception, information interconnection, situation prediction and early warning, disaster prevention and control, scientific and efficient decision-making, and visible and available results. 

The system also links with the district-level Guangming Management Service Command Center and the Guangming Emergency Management Center, enabling comprehensive perception of the whole network, full system graph visualization, and one-click decision making – a new concept in environmental water management.

The system can comprehensively perceive and aggregate network-wide indicator data on the environment and water supply. Users can check various aspects and the overall situation of the environment and water supply across the whole district with the one-graph service. They can view an entire event and remotely monitor the on-site situation using the intelligent environment and water monitoring and early warning services, and then implement unified command and resource deployment through an emergency response system. Results data provided by the system data service can support decision-making.
