In the final assembly plant of CRRC Chengdu Company, located in the modern transportation industry functional area of Xindu District, a subway train
is operated by him and his colleagues, from the frame to the whole vehicle, from the “empty shell” to the entire core. The electronic torque wrench in
the hand of the operator Xue Tiankai has its own measurement and wireless transmission function, the bolt is not tight, it used to need manual
confirmation, and now look at the working system on the computer beside it, efficient and accurate. Based on the construction of a strong chain,
Chengdu rail transit industry goals are clear: by 2025, the advantages of the whole industry chain of “survey and design – engineering
construction – equipment manufacturing – intelligent operation and maintenance and value-added services” are further highlighted, and strive to
reach 280 billion yuan in the main business income of the whole industry chain.

Here, through the system industrial design and completion of the vehicle, doors, gear boxes, bogies, air conditioning and other production lines, make the
vehicle maintenance process more compact connection, vehicle maintenance efficiency increased by 8%. The smart factory took the lead in introducing
CRRC’s MRO (urban rail maintenance system), IOT system (production line digital system) and other production management systems, opening up the data
link of all links of production and manufacturing, realizing the information sharing of vehicle maintenance process, procurement, production, quality and
other links, and comprehensively improving the level of production intelligence. “For traditional maintenance, workers have to go to the site to collect data,
measure, analyze, and then carry out ‘replacement surgery’ and ‘post-operative detection’.” The MRO urban rail maintenance system will collect the data of
the whole life cycle of the train and integrate it to form a simulation interface similar to the ‘meta-universe’ to make the maintenance more efficient.”
there are bolt torque operation “electronic supervisor”, the end of this year will also introduce automatic robot production line…

The 14th Five-Year Plan for the Development of Chengdu Rail Transit Industry (Draft for Comments) proposes that by 2025, the advantages of the whole
industry chain of “survey and design – engineering construction – equipment manufacturing – intelligent operation and maintenance and value-added services”
will be further highlighted, and the main business income of the whole industry chain will reach 280 billion yuan. In terms of the development of rail transit
equipment industry, strive to 2025, Chengdu rail transit equipment manufacturing main business income reached 55 billion yuan, accounting for more than
20% of the whole industry chain, vehicle equipment supporting capacity reached more than 70%, mechanical and electrical system supporting capacity reached
more than 30%. Chengdu rail transit ecological circle will be further improved and expanded.
