2 Wisdom Tracks
Guide: At the 2022 (Sixth) China Urban Rail Transit Smart Operation and Maintenance Conference, Wang Jianwen, director of the Mechanical and Electrical Department of the Xi'an Branch of Guangzhou Metro Design and Research Institute Co., Ltd., published the "Integrity and Innovation: Summary and Future Development of Xi'an Metro Smart Station Design" The report summarizes the current development of smart stations and the development ideas of smart stations on the new line.
Guide: The "Metro Safety Emergency Guarantee Application" created by Ningbo Rail Transit Group was selected for the 2022 Ningbo City Digital Reform Best Application Award, using digital twin technology to realize the integration of "emergency scenarios, panoramic monitoring, monitoring and early warning, command and dispatch, and air defense research and judgment" , information maintenance, and mobile emergency” equal to an integrated digital and intelligent emergency command platform.
(3) AxxonSoft: The world's leading AI video management platform manufacturer
Guide: Axxon One VMS products are characterized by openness and AI intelligence. Compared with traditional video security, the application of AI artificial intelligence technology in its products can help users realize many new capabilities. It includes functions such as intelligent video retrieval, video concentration, human anomaly detection, fence intrusion detection, smoke and flame detection, and image quality detection.
Guide: Creating a comfortable riding environment is inseparable from the control and adjustment of the intelligent system. Today, I will introduce to you the highly efficient intelligent environmental control system innovatively used in the fourth phase of the Shenzhen Metro project, and see its "magic" "Let's go~
3 track knowledge
(1) "Black technology" blessing! All the track switching tasks on this line have been completed
Guide: The Beijing-Shanghai railway track change construction operation has been fully upgraded in terms of digitization, automation, and intelligence. For the first time, the HGCZ-2000 mechanical track change vehicle integrating many "black technologies" has been applied. The 4 rails are replaced synchronously, with functions such as self-propelled rail replacement, automatic rail entry into the groove, automatic recovery of fasteners, etc., stepless speed regulation, and strong controllability. It can also be used in special rail replacement areas such as bridges, tunnels, and small radius curves. Perform rail changing operations safely and efficiently.
(2) Small science popularization of railway knowledge | Do you know the rail telescopic regulator?
Introduction: The rail expansion regulator, also known as the temperature regulator, is a kind of track equipment that adjusts the expansion and contraction of the rail. A rail telescopic adjuster is installed on the rail, and the expansion and contraction of the rail can be adjusted by using the relative displacement of the tip rail or the basic rail. It is commonly used on long-span steel girder bridges, bridge heads and seamless lines where the amount of expansion and contraction of the steel rail needs to be adjusted. So, do you know how a regulator works? How is the application in our country?
Guide: Recently, the China Urban Rail Transit Association released the "Urban Rail Transit 2022 Statistics and Analysis Report". The data shows that by the end of 2022, a total of 55 cities in mainland China (excluding Hong Kong, Macao and Taiwan) have opened 308 urban rail transit lines. , the total length of operating lines exceeds 10,000 kilometers.

Introduction: Meta releases the first image segmentation basic model in history, SAM, which introduces the prompt paradigm in the NLP field to CV, allowing the model to cut out images with one click through the prompt. Netizens shouted: CV no longer exists!
(2) The time for general vision GPT is coming? Zhiyuan launched a general segmentation model SegGPT
Introduction: A few days ago, Meta released the SAM model, and as far as we know, almost at the same time, the vision team of Zhiyuan Research Institute also launched a general segmentation model SegGPT (Segment Everything In Context) - using visual prompts (prompt) to complete arbitrary segmentation A generic visual model for tasks. So, what is the difference between the two models?
Guide: Always short of words when facing paintings? Now, Midjourney has launched a new image tool that works in reverse, as long as you enter an image, it will output a prompt for you. In front of this AI painting tool, the gap between people may be reflected in the prompt. Many times now, a line of perfect and professional prompts is already worth thousands of dollars. And Midjourney seems to know our needs very well. Recently, it launched a new function - /describe, which can help us deduce the prompt from the image.
