2 Wisdom Tracks
Guide: Urban rail vehicle trackside comprehensive intelligent detection system , consists of five subsystems of vehicle body 360° detection, wheel set detection, pantograph detection, power shoe detection, temperature detection of key components of the running part and an intelligent detection system for trackside vehicles Platform composition. The system uses advanced artificial intelligence detection and identification technologies to conduct real-time intelligent and digital detection of key components of the train, including running gear, traction, current collector, brake air supply, pantograph and other devices. Effectively improve detection efficiency and quality, reduce operation and maintenance costs, and open a new model of vehicle intelligent operation and maintenance.
(2) Changzhou subway intelligent inspection robot family has added new members
Guide: A new member of the Changzhou subway intelligent inspection robot family - "Tie Shuai", uses 2 line array cameras and 3 3D cameras to simultaneously collect two-dimensional images and The three-dimensional data can realize the qualitative identification and quantitative measurement of visible defects on the track, automatically give key information such as the location, type, and size of the disease, realize the diagnosis and early warning of track equipment failures, and then realize its intelligent maintenance decision-making support function.
(3) Comprehensive detection system for subway tunnels, escorting the safety of urban rail
Guide: The subway tunnel comprehensive detection system is composed of 8 subsystems, tunnel convergence deformation detection subsystem, tunnel appearance detection subsystem, ballast bed appearance detection subsystem, rail detection subsystem, fastener detection subsystem, evacuation platform detection subsystem , The drainage ditch detection subsystem and the positioning subsystem can be selectively configured according to user needs. The system can also be integrated and installed on road-rail vehicles or power vehicles. The dynamic detection speed can reach 35 km/h, and the massive data detected are processed by computer and artificial intelligence deep learning to give the tunnel disease index and the precise position relative to the 100-meter mark.
Guide: During the 2023 Beijing-Qingdao International Urban Transportation Expo, Huawei released the white paper "Ten Trends of Smart Urban Rail ICT Technology" (hereinafter referred to as the white paper). The white paper covers the development of smart urban rail and future technology forecasts. Introduced the development trend of ICT technology that needs to be paid attention to in the process of upgrading urban rail transit to smart urban rail, and pointed out that artificial intelligence, cloud native technology, storage and computing integration, interconnection, cloud-edge collaboration, all-optical network, 5G, and cloud-network security collaboration The top ten ICT technologies represented by , digital twins, etc. will have an important impact on the informatization and digitalization of the urban rail industry in the next three to five years. It is expected to provide reference and reference for the intelligent and autonomous construction of urban rail transit in the future. The official account "Zongeryanzhi" replies "Huawei Smart Urban Rail" to download the white paper.
Guide: What breakthroughs and progress has Guangzhou Metro Design and Research Institute made in terms of intelligent and green rail transit? What is the future plan? Survey and design play a leading role in engineering construction, how to achieve the integrated development of design-construction-operation-city? How do you view the difficulties and challenges facing the development of the industry? In response to these problems, "World Rail Transit" magazine interviewed Nong Xingzhong, a master of engineering survey and design in Guangdong Province, chairman and executive chief engineer of Guangzhou Metro Design and Research Institute Co., Ltd.
3 track knowledge
(1) Science Popularization - Train Virtual Marshalling Technology
Introduction: What is train virtual marshalling technology? What is the background, advantages and operation mode of virtual marshalling technology? Where is the application currently available?
(2) What is the use of these "rods" for railway power supply...
Guide: Friends, do you know that poles can also become a sharp weapon to ensure the safety of railway power supply. You must be curious about what these "poles" are used for. Today, follow the editor to understand.
(3) The first in China! Officially put into use!
Guide: On April 20, the first integrated machine for changing and transporting racks in China completed the replacement of masonry beams on the No. 149 Bridge of Shuohuang Railway of the National Energy Group and was officially put into use. The all-in-one machine for changing and transporting is the first in the world to adopt the folding design concept, and the whole machine has the function of changing and transporting postures.
(4) [Information] Rusty steel rails are still in service, are they safe?
Guide: When you see the rusty rails, you will inevitably have doubts in your mind. Can you still guarantee the safety of operation? Take it easy, the editor will take you to explain the reason.
(5) Why do subway drivers have to get off at every stop to "gesture"?
Guide: If you are on the way to work, if you happen to take the subway, you can see if the subway driver makes any gestures. Then, "Why does the subway driver get out of the car and sign ahead with his hand every time he arrives at a station?" "Look behind the glass door, is the subway driver greeting me?" What exactly did the subway driver do to make passengers have such questions and concerns? misunderstanding? Let me give you an answer.
