2 Wisdom Tracks
Introduction: Technology is the primary productive force, and smart technology has long been used in all walks of life. Today, I will take you to know about this "special" new colleague of Nanning Metro Line 4. It is the 360° intelligent comprehensive detection system for urban rail vehicles , a new type of intelligent detection system for electric passenger cars. Here are a few Q&As to unveil the mystery of the 360° intelligent comprehensive detection system for urban rail vehicles.
(2) Sharing | Thinking and prospect of intelligent operation and maintenance construction
Guide: In order to improve the efficiency of subway maintenance and reduce the maintenance cost of the whole life cycle, in response to the "Outline for Building a Powerful Transportation Country", various majors in the subway industry have carried out research and preliminary construction of intelligent operation and maintenance equipment, and achieved a series of results, but intelligent operation Maintenance construction is still in its infancy, and there is still a lot of room for improvement. Through the analysis of the current situation and thinking about the problems existing in intelligent operation and maintenance, we will explore the future development direction of intelligent operation and maintenance construction.
(3) The digital twin screen of the Shenzhen Metro was officially launched
Guide: Recently, the Shenzhen Railway Group’s digital twin large screen, undertaken by Shenzhen Municipal Design and Research Institute Co., Ltd., was officially launched. The system uses the BIM technology application comprehensive platform self-developed by Shenzhen Railway Group as the carrier. With the help of NOCC phase II management cloud data center computing power resources, high rendering engine, big data platform, and integration platform capabilities, it integrates business data of each unit of the group, and through digital twin The technology focuses on the BIM/CIM application in each stage of the full life cycle of Shenzhen Railway Group, including planning, survey and design, civil construction, post-station construction, completion and handover, and operation and maintenance.
Guide: The Wuhan High-speed Rail Works Section took the lead in developing an integrated high-speed rail inspection platform that integrates "line inspection, fastener inspection, track plate inspection, bridge culvert inspection, and flaw detection" with Wuhan University and Hanning Rail Company . The use of this testing platform will save more than 3 times the human resources. After the high-speed rail centralized inspection becomes normal, it will greatly solve the situation of personnel shortage and scattered safety card control points.
(5) Take the lead in China! This "line" is super high energy
Guide: Recently, the train bogie for the first C-level repair of Chengdu Rail Transit Line 18 was successfully accepted and delivered at Chengdu Rail Equipment Smart Factory, marking the official completion and commissioning of the cross-platform vehicle bogie repair production line of Chengdu Rail Equipment Smart Factory. The commissioning of the bogie inspection and repair production line means that the layout of the core capability of Chengdu rail equipment smart factory "vehicle + bogie + large parts" vehicle inspection and repair has been basically completed, which will effectively promote the upgrading of Chengdu's rail transit vehicle equipment industry chain and provide Chengdu with The industry's "building a circle and strengthening the chain" has added new momentum.
(6) Railway science class | What drones can do in the field of railway engineering
Introduction: As a multi-purpose product transitioning from high-end military equipment to civilian consumer grade, drones have gradually penetrated into our lives. So in the field of railway engineering, what are the applications of drones? The following will combine the typical application cases of various stages of railway engineering to tell you about the technological changes brought about by drones in the field of railway engineering.
3 track knowledge
(1) How many types of "doctors" are there in this high-speed rail exclusive "hospital"?
Guide: As the only transportation production unit of Beijing Bureau Group Corporation that integrates the operation and maintenance of bullet trains and passenger cars, Tianjin Railway Passenger Depot is the exclusive "hospital" for railway passenger vehicles. There are a large number of professional maintenance "doctors" here to ensure that railway passenger vehicles are maintained all year round. Maintain a good operating condition and escort the safe travel of passengers. Let's see what "doctors" are there!
(2) Why does the railway lady have to look at the "electrocardiogram" at work?
Introduction: You must be familiar with the electrocardiogram. Doctors can judge whether our heart is beating healthy through the electrocardiogram. In the Beijing Bureau Group Company, some railway ladies stared at the "electrocardiogram" on the screen like a doctor when they went to work. what are they doing Come and take a look with me!
(3) Railway science class | Why can the subway be aimed at the screen door when it stops?
Guide: The subway now has two operating modes, one is driven by a driver, called manual driving, and the other is unmanned, called automatic driving. So how do they aim at the screen door?
Guide: Foreign matter invasion refers to the event that foreign matter outside the railway invades into the railway boundary. Generally speaking, geological disasters such as collapses, landslides, and mudslides, domestic waste such as plastic cloth films, hydrogen balloons, vehicles, and construction waste belong to railways. Invasion of foreign bodies. If foreign matter invades the railway and is not detected in time, it often leads to train delays and even traffic accidents. So, what detection methods are currently available?
(5) The "partner" of the railway signalman
Guide: Most of the tools used by railway signal workers are not big but useful. These tools are the "close partners" of signal workers, helping them complete every task. Today, let's take a look at the "partners" of the signal workers of the Kunming South Electricity Section of the Kunming Bureau Group Company.
4 Extended reading
Guide: The Ministry of Transport, the National Railway Administration, the Civil Aviation Administration of China, the State Post Bureau, and China State Railway Group Co., Ltd. jointly issued the "Five-Year Action Plan for Accelerating the Construction of a Powerful Transportation Country (2023-2027)". Let's see what are there focus direction.
(2) Unlock productivity with large models, SenseTime is serious
Guide: On April 10, SenseTime shared the strategic layout of promoting the development of AGI (General Artificial Intelligence) with "big model + big computing power", and announced the "Daily New SenseNova" large model system of SenseTime under this strategy , So, is it reliable and what can it do for us?
(3) AIGC's next stop: expect and be wary of a world full of AI editors
Introduction: Like other AIGC technologies, Text2Video is rapidly entering our lives. This paper summarizes the development process of this technology, and can have a systematic understanding.
(4) Meta latest | After splitting everything, Segment Anything can distinguish categories again!
Guide: A few days ago, Meta launched the "segment everything" AI model Segment Anything, making netizens call CV no longer exist? ! In another paper included in CVPR 2023, Meta and UTAustin jointly proposed a new open language style model (open-vocabulary segmentation, OVSeg), which allows the Segment Anything model to know the category to be segmented.
