With the popularization of new infrastructure, digital technology is becoming a hot word at this stage. High-speed EMU is the heavy weapon of the country. What about now? Revival? Running on the vast land of the motherland, leading the world at a speed of 350 kilometers. Revival? From car body welding, bogie installation to overall calibration and operation and maintenance, digital technology plays a particularly important role in the whole manufacturing process of EMU trains.

Bogies are equivalent to trains? Hands and legs? , is an important key component of EMU trains. Yao Di, a bogie process engineer, said that a bogie has more than 400 kinds of spare parts, which will cause nearly 10,000 pieces of manufacturing data information from shelf installation to completion of manufacturing. These people use the intelligent assembly line of bogies, rely on the Internet of Things, intelligent sensors and other technologies, take intelligent products led by CNC lathes, collect torque and assist in installation, carry out online centralized control, and complete automatic collection, automatic judgment and automatic collection of bogie manufacturing data and information.

The traceability of the whole manufacturing process can scientifically and reasonably ensure the installation quality of bogies. In addition, relying on the installation of cloud computing technology, we can deeply analyze the first-time inspection compliance rate, process capability index value and quality reliability of enterprise products, so as to guide the improvement of production technology and manufacturing process and improve production efficiency and product quality.

Relying on cloud computing technology, the company built an intelligent operation and maintenance service platform for EMU trains. Here, cloud computing technology has been applied to the operation and maintenance management of EMU trains, which has become a reliable new way to escort EMU trains. Artifact? . ? This operation and maintenance management mode based on cloud computing technology changes the traditional passive problem into active predictive maintenance, which can reduce the failure rate of train equipment, scientifically and reasonably ensure traffic safety and improve the efficiency of operation and maintenance management. ? At present, the intelligent operation and maintenance service platform for EMU trains has been put on the shelves, with nearly 100 problem prediction models and cloud computing technology, which can successfully prevent hundreds of security risks every year.
