He listened to an introduction about the world's largest high-speed rail network, praised its safe and environmentally friendly design, and regarded the earthquake early warning system as a miracle of modern engineering."

Earthquakes pose the greatest threat to the safe operation of high-speed trains among natural disasters, as they can directly damage railway infrastructure and lead to serious consequences such as train derailments and overturnings.
The earthquake early warning system utilizes the speed difference between P-waves and S-waves to issue early warning information before the arrival of destructive S-waves during an earthquake. When an earthquake occurs, the monitoring unit calculates real-time early warning information for a single unit, transmits it to the front-end early warning server, and uses a regional early warning algorithm to generate early warning information for multiple units. It calculates the scope of emergency response and sends it to the traction power supply system, train control system, and on-board devices to achieve emergency braking of the train.

The high-speed railway earthquake early warning system independently developed by the company has successfully passed the first round of technical review by the China Railway Group and obtained CRCC certification from the China Railway Inspection and Certification Center. It has been widely applied to key lines such as the Beijing-Zhangjiakou High-Speed Railway, Beijing-Xiongdu High-Speed Railway, Chengdu-Chongqing High-Speed Railway, Chengdu-Guiyang High-Speed Railway, and Zhengzhou-Jinan High-Speed Railway, effectively enhancing the disaster prevention and mitigation capabilities of the national intelligent high-speed rail. It continues to contribute to the high-quality, intelligent, and digital development of national rail transit.
