(1) Consolidate the foundation of smart transportation and create a "smart transportation brain"
Introduction: Recently, the “Beijing Transportation Development and Construction Plan during the 14th Five-Year Plan Period” (hereinafter referred to as the “Plan”) was released. The "Plan" clarifies that during the "14th Five-Year Plan" period, a comprehensive, green, safe, and intelligent three-dimensional modern urban transportation system will be initially built, and transportation development will reach a new level. The "Plan" points out to improve the level of transportation intelligence and create "smart subway", "smart bus", "smart parking" and "smart road" demonstration projects. By 2025, the total mileage of smart roads will exceed 300 kilometers.
Introduction: On August 11, Chengdu Rail Group released the "Action Plan for Green Urban Rail Development" and "Top-level Plan for Digital and Intelligent Development", marking the start of a new journey for Chengdu Rail Transit to be led by technology and empowered by green intelligence. Chengdu Rail Group has always closely adhered to the urban development strategy and bravely shouldered the mission of rail city development. It was the first in China to quantitatively propose a green transportation structure model for central urban areas, achieving a rail transit bus travel sharing rate of more than 60%, and actively focused on the eight construction systems of smart urban rail. We will make every effort to promote the construction of a number of projects such as smart transportation, smart equipment, and smart networks, and promote the transformation of urban rail transit into green, low-carbon, and smart.
Introduction: The railway comprehensive video surveillance system (referred to as the video surveillance system) is to meet the needs of railway traffic command, production organization, passenger transport services, operation monitoring, rescue and public security, etc., applying video and audio surveillance, communications, computer networks, and cloud computing , cloud storage and other technologies, combined with intelligent analysis technology, a monitoring system with video and audio line-of-sight collection, transmission, control, display, storage, processing and other functions. With the increasing development of high-speed railways in my country, video surveillance systems have gradually expanded their application in the fields of high-speed railway transportation command, production operations, operation management, and security maintenance. They have become a key scientific and technological guarantee for safe production, improved efficiency, and strengthened management of high-speed railways.
(4) [Information] New technologies for heavy-duty railway vehicles
Introduction: In addition to using high-power locomotives for traction, heavy-haul railways also need special vehicles to match them. These railway vehicles should have different structural properties from ordinary freight cars and have many unique technologies. Come and see what technologies are available. Bar.

(1) Dimensions of common railway containers and meanings of container marks
Introduction: Railway container transportation is an important part of the modern logistics industry. As China's economic development enters the new normal and the implementation of the "One Belt, One Road" strategy, especially the separation of railway construction and development and railway reform between government and enterprises, railway container transportation faces important challenges. The development opportunities will become an important strategic direction for the development of China's railway freight and an important symbol of the market-oriented transformation of China's railways.
(2) What is the "closed car" that railway people often say
Introduction: In this issue, we learn about the "closing truck" from the following three aspects: 1. What is a closing truck; 2. How to determine the closing truck; 3. The relevant regulations on the arrangement and hanging of closing trucks.
(3) What is the difference between the trains with this sign on 12306?
Introduction: During the summer, if you are traveling by high-speed rail, when purchasing tickets on the Railway 12306 APP, have you noticed that in addition to the "Fuxing" logo, there are also the words "Smart EMU" on the top of some trains ? Yes, this is the Fuxing smart EMU train! Today, the editor will take you to take a closer look at the differences between the Fuxing smart EMUs!
(4) Force the car to stop! The verdict was to award more than 30,000 yuan in compensation!
Introduction: Do you know what the consequences will be if a dustproof net worth dozens of dollars "flys" onto a high-speed rail ? Earlier, the dust-proof net in a building materials factory in Shenyang City, Liaoning Province was not reinforced in time , and was blown by strong winds to the catenary between Shenyang South Station and Benxi New City of the Shenyang-Danzhou High-speed Railway, causing six EMUs to be delayed by 1 hour and 5 minutes . Later, the court ruled that the building materials factory should compensate the railway department for the loss of transportation capacity, emergency rescue fees and appraisal fees in accordance with the law, a total of 32,636 yuan .
Introduction: This year’s Chinese patent award-winning projects, CRRC Zhuzhou Institute’s “Frequency conversion device and its power expansion method” won the gold medal; CRRC Research and Design Institute’s “An online detection method and device for track circuit cable faults”, CASCO Signal Company’s “A Method for Implementing Flexible Grouping Operations of Urban Rail Transit”, Guangzhou Metro Design Institute’s “A Station-Tunnel Co-constructed Column-free Subway Station Transfer Node Structure and Construction Method”, China Railway Fifth Institute’s “Full Casing and Fully "Rotary Drilling Rig Equipment" won the silver award.
4 AI industry
Introduction: With the emergence and maturation of large models, the dependence of large-scale language models (LLMs) on larger-scale training data and the issues of data privacy and business competition have given rise to a new problem, how to do it without violating the legal provisions of data privacy On the basis of jointly training a large-scale language model using isolated data in the private domain of various commercial entities ? This article may give you the answer.
Introduction: Recently, Wisdom has released the most powerful open source commercially available Chinese and English semantic vector model BGE (BAAI General Embedding). Its Chinese and English semantic retrieval accuracy and overall semantic representation capabilities have surpassed all similar models in the community, such as OpenAI's text embedding 002, etc. . Zhiyuan Research Institute will continue to open source more complete large-model full-stack technologies to the academic and industrial circles.
(3) The working principle of the popular deconstructed language model
Introduction: How does the large language model work internally? This article explains with minimal math and terminology.
Introduction: This article systematically introduces the development process and technical principles of large visual models, which has great reference value!
(5) Use ChatGPT to hire a McKinsey consultant
Introduction: I believe many people know McKinsey. About 70% of the top 100 companies in the world are its clients. It gathers the smartest brains in the world and cultivates many top management thinkers and business leaders. Today we use chatgpt to create a McKinsey industry research assistant.
