Smart rail transit empowers urban development, Guangdong-Hong Kong-Macao Greater Bay Area extends to the future
On Line 18 and Line 22 of the "Fastest Metro in the Greater Bay Area" with speeds of up to 160 kilometers per hour, passengers only need to register their personal information on the Guangzhou Metro App with their real names, bind to WeChat Pay, and use the face-scanning device to "reveal". "A face", you can pass the turnstile "without feeling", eliminating the trouble of rushing to find and swipe your card.
When the passenger flow is congested during peak hours, mobile apps, station broadcasts, electronic guidance screens, escalators and other equipment will be automatically linked and controlled to display the congestion degree of each car in real time, and guide passengers to cars with lower crowd density.
Station staff at the station can use the full HD digital video system to perform intelligent video patrols, smart security checks, one-key switch stations, one-key start of emergency plans and other automated operations.
Behind the intelligent function is the Suiteng OS system jointly launched by Guangzhou Metro and Tencent.
It is understood that Suiteng OS is a rail transit operating system based on emerging technologies such as the Industrial Internet and the Internet of Things.
On September 23, Suiteng OS system was fully renewed, and version 2.0 was released to help Guangzhou Metro to re-enable its "smart" upgrade, empowering the construction of smart city clusters in the Guangdong-Hong Kong-Macao Greater Bay Area and extending it into the future.

Guangzhou Metro fully "upgrades" its digital system and "escorts" rail transit in all directions
In September 2019, Suiteng OS1.0 version of the Smart Metro Demonstration Station was launched at Guangzhou Tower Station on the APM Line of Guangzhou Metro.
On September 23, 2021, Guangzhou Metro and Tencent jointly released the Suiteng OS2.0 version, further strengthening the capabilities of the Internet of Things and integrated data processing capabilities.
The demonstration operation of Guangzhou Metro Line 18 and Line 22, which will be opened soon.
Suiteng OS has realized the cross-border integration of Internet technology and rail transit. By establishing a unified IoT standard, it has truly realized the interconnection and intercommunication of rail transit equipment and systems.
It can support intelligent rail transit services such as intelligent passenger flow guidance, intelligent station services, intelligent security, intelligent dispatch, and vehicle automation operation and maintenance, and realize unified intelligent dispatch management.
Use the rail transit smart operating system as the extension medium to accelerate the digital transformation, smart upgrade, and smart extension of the rail transit industry.
Zhong Xiangping, vice president of Tencent and president of Tencent Smart Transportation and Mobility, said that Suiteng OS2.0 helps to open up the "data islands" of each subsystem of rail transit, and realize the unified dispatch of industrial resources and full life cycle management.
This will profoundly change the construction and operation mode of rail transit, from the original "rebuild" to "growable and evolve", and drive the industry to further reduce costs and increase efficiency, transform and upgrade.
For example, incidents of items caught in subway doors have occasionally occurred in the past, but the foreign object detection function on platform doors of smart stations can effectively solve this problem.
This function is based on the time-of-flight principle (TOF), using a top-mounted, transceiver integrated lidar sensor to monitor the gap between the train door and the platform door, with no intrusion limit, programmable, low false alarm rate, and reliability The high characteristic greatly reduces the probability and risk of accidents and ensures the safety of passengers getting on and off the bus.
In addition, in the fields of security inspection, lighting, station management, video monitoring, and escalator monitoring, Suiteng OS has also realized the "all-round escort" of rail transit.
The degree of congestion in the carriages is “visible”, and the flood prevention monitoring guards the passengers' “lifeline”
A few days ago, the first pass of Guangzhou Metro Line 18 (Xiancun-Wanqingsha) ushered in the first batch of passengers.
It is estimated that by taking Line 18, passengers can reach Panyu Square from Xian Village in 15 minutes, and "fly" from Tianhe to Wanqingsha Station in Nansha in 29 minutes.
The first section of Guangzhou Metro Line 18 will be put into operation within this year. By then, the time and space goal of a 30-minute drive from Nansha Sub-center to Guangzhou Central City will be achieved.
The opening of the first section of Line 18 is a microcosm of the continuous expansion of the Guangzhou Metro network in recent years.
At the same time, the passenger flow of Guangzhou Metro is also showing a trend of rapid growth.
The data shows that Guangzhou Metro has undertaken more than 44% of the bus passenger transport tasks in Guangzhou. In 2020, the passenger traffic intensity of China's subway will be 5,700 passengers/day kilometers, of which the passenger traffic intensity of Guangzhou Metro will be 12,400 passengers/day kilometers, which is the highest level in the country. The highest single-day passenger flow reached 11.13 million.
High-intensity passenger flow pressure, as well as citizens' needs for subway travel time, transfer convenience, and operating service time, make it imperative for Guangzhou Metro to improve its dispatch and command capabilities.
In the past, in traditional subway stations, the slogan "Please pay attention to scattered rides" can be seen everywhere, but passengers cannot judge for themselves which car has a smaller traffic volume.
According to the developers of the Suiteng OS system, sensors are installed in the subway cars to calculate the congestion degree of each car. If this set of data can be filled into the broadcast system and smart screen display, it can effectively remind passengers of the number of cars. The degree of congestion is low, and passengers are guided to ride in less crowded carriages.
This seemingly simple function, but involves multiple business system units, may cost tens of millions of yuan for linkage upgrade and debugging, which is not only time-consuming and labor-intensive, but also difficult to get through data barriers.
However, after connecting to the Suiteng OS2.0 system, it is possible to realize the interconnection and intercommunication of the subway's sensing equipment, monitoring system, gates, elevators, broadcasting, APP and other equipment, and use the video intelligent analysis algorithm to analyze the platform area in real time. Based on the platform-train passenger flow balance algorithm, it automatically guides passengers to queue up in areas with few people through radio broadcasting, large information screens, mobile apps, etc.
In addition, in response to the increasingly important problem of subway flood control, station operators can also use liquid level sensors installed at flood control risk points to grasp the flooding position and water volume of the station in real time. Once the water level reaches the early warning threshold, they can use Suiteng OS2.0 one. Press the key to start the emergency plan for flood prevention at the station, realize automatic push of early warning information, and quickly link station broadcasting, escalators, turnstiles and other equipment to guide the evacuation of passengers in an orderly manner.
Based on Suiteng OS Internet of Things, big data, algorithms and other platforms, it creates a comprehensive map of flood control information for stations and sections to provide assistance for emergency response and rescue decision-making, and build the "underground lifeline" of millions of citizens.
In terms of station management, based on the strategy engine platform of Suiteng OS, a scene mode control including one-key switch station, video patrol inspection, one-key start of station emergency plan and full-process tracking has been constructed, realizing mobile station affairs management. , Reduce operation and management costs.
At the same time, combined with Tencent Cloud's small and micro intelligent voice, knowledge map and other AI technologies, it significantly improves the level of automated office and improves the efficiency of station management.
Relaying the integration of transportation in the Guangdong-Hong Kong-Macao Greater Bay Area "Smart Metro" is promising
In September of this year, Guangdong Province issued the "Fourteenth Five-Year Development Plan for the Comprehensive Transportation System of Guangdong Province" (hereinafter referred to as the "Plan"), which clarified the long-term and short-term construction and development plan for promoting a strong transportation province.
The "Plan" clearly stated that by 2025, a comprehensive three-dimensional transportation network layout will be basically formed, passenger and cargo transportation service quality will be significantly improved, comprehensive transportation management capabilities will be further enhanced, and a modern comprehensive transportation system that runs through the whole province, smoothly domestically, and connects the world will be established. , The high-quality development of transportation is at the forefront of the country.
The layout of the comprehensive three-dimensional transportation network is inseparable from the construction of urban rail transit. In the Guangdong-Hong Kong-Macao Greater Bay Area, the integrated layout of "intercity + subway" rail transit has been in place for more than ten years.
As early as 2010, China's first inter-city subway Guangfo Line started operation.
In 2017, the west extension to Shunde section of Guangzhou Metro Line 7 was launched. At the same time, the Guangzhou-Foshan urban rail transit interconnection plan was approved by the two municipal governments, and a total of 11 subway interconnections of "9+2" were proposed.
In addition to Guangzhou and Foshan, in 2018, Dongguan, Zhongshan, Zhuhai, Qingyuan and Guangzhou will start to link up their rail links.
In February 2019, the "Guangdong-Hong Kong-Macao Greater Bay Area Development Plan Outline" was officially issued, putting forward the overall requirements for "building a rapid transit network in the Greater Bay Area", "accelerating the construction of intercity railways, and orderly planning urban rail transit projects in major cities in the Pearl River Delta" .
So far, the construction of urban rail transit in the Guangdong-Hong Kong-Macao Greater Bay Area has once again reached a new level, and the role of Guangzhou Metro has become increasingly important.
Guangzhou Metro prepares or undertakes the Guangqing Intercity Railway (Guangzhou North-Qingyuan), New Baiguang Intercity Railway (Xintang-Guangzhou North), Zhuhai-Jiangsu Intercity Railway (Gongbei-Hengqin), Guangzhou-Foshan Ring Line (Guangzhou South-Foshan West) ) The operation and management of the four inter-city railways is designed to have a speed of 160 to 200 kilometers per hour, thus constructing the Guangdong-Hong Kong-Macao Greater Bay Area rail transit operation mode of "one network, one ticket, one city".
Ma Huateng, representative of the National People’s Congress and Chairman and CEO of Tencent’s Board of Directors, said in an interview that Tencent is discussing with Guangzhou Metro that it can also use the Internet to further improve the intelligent construction of rail transit in the Greater Bay Area and promote Guangzhou to play its role as a comprehensive transportation hub. .
Ma Huateng said that the Greater Bay Area is one of the busiest traffic areas in China. If the next step is to improve the intelligent transportation standards in the Greater Bay Area, it will definitely give full play to the regional advantages and have a lot to do.
Building a world-class rail transit brand An important boost to the integration of Guangzhou Metro into the Greater Bay Area
Since its official opening in 1997, Guangzhou Metro has become a super system with 16 lines and an operating mileage of 553 kilometers.
In the context of the national transportation power strategy and the construction of the Guangdong-Hong Kong-Macao Greater Bay Area, the goal of building a world-class large-scale integrated transportation hub has been clarified, and a number of policy guidelines have been issued, requiring the acceleration of the intelligent construction of rail transit and boosting the "hard connectivity of infrastructure" ", technological innovation "intelligent connectivity", to create a world-class rail transit brand.
In 2019, Guangzhou Metro Group Co., Ltd. released the "New Era Urban Rail Transit Innovation and Development" white paper. The white paper described the blueprint of "Intelligent Rail Transit": the new era of urban rail transit should be user-centric and a new generation of artificial intelligence technology. As the core, taking passengers and equipment as the object, build a data-driven new era advanced urban rail transit information integration system architecture system to meet the diversified needs of the government, enterprises, society, and passengers for urban rail transit.
In this context, Guangzhou Metro and Tencent jointly established a Suiteng Joint Laboratory, dedicated to the research and development of a new generation of rail transit operating systems.
Suiteng OS 2.0 version builds Suiteng OS's component development capabilities, strategy orchestration capabilities, microservice capabilities, big data capabilities, algorithm hosting and intelligent dispatch capabilities, focusing on supporting the development of intelligent integrated management and control of rail transit lines, and line network dispatching and commanding services , To provide a solid foundation for the digital upgrade of the entire life cycle of the rail transit industry.
After a small amount of adaptive customized research and development, Suiteng OS can also be widely used in more complex industrial fields such as smart transportation and smart cities in the future.
Tang Daosheng, Senior Executive Vice President of Tencent and CEO of Cloud and Smart Industry Group, said at the Suiteng OS2.0 press conference that Tencent, as an assistant of digital upgrades in various industries, will continue to work with Guangzhou Metro to promote emerging technologies and rail transit business The cross-border integration of the industry will help build the Greater Bay Area on the track and help the digital upgrade of the transportation field.
Ding Jianlong, chairman of Guangzhou Metro Group, said that the launch of Suiteng OS2.0 has reconstructed the design concept of traditional industrial control systems, and will further assist the digital transformation and upgrading and high-quality development of my country's rail transit industry, and boost the foundation of the Guangdong-Hong Kong-Macao Greater Bay Area. The interconnection of facilities contributes wisdom and strength to building a strong transportation country.
As the highlight of a smart city, smart transportation is promising.
In July 2019, the "Implementation Opinions on the Implementation of the Outline of the Development Plan for the Guangdong-Hong Kong-Macao Greater Bay Area" issued in July 2019 stated that by 2035, the Guangdong-Hong Kong-Macao Greater Bay Area will be fully integrated, integrated, three-dimensional, open and integrated. The comprehensive transportation network has promoted the Greater Bay Area to become a world-class bay area that is livable, workable and travelable.
