On December 26, Changsha West EMU station was officially opened. The digital, visual and intelligent safety interlock operation maintenance and control information system is firstly applied in the domestic high-speed and EMU stations, marking a new step towards digital maintenance and intelligent management and control of high-speed rail.

Since the beginning of this year, the work of EMU repair system reform, independent maintenance and supporting capacity building has been advanced in an orderly manner, and the construction of digital EMU trains with information maintenance, standardized operation, intelligent equipment, and integrated safety and quality control has been put on the agenda.

We cooperated with Huazhong University of Science and Technology to focus on key safety and quality core issues of high-speed and EMU trains , maintenance personnel, maintenance process and maintenance equipment, based on the safety application experience of high-speed EMU train safety interlock monitoring system and relying on advanced technologies such as intelligent manufacturing, digital equipment and industrial fieldbus. Using reliable industrial fieldbus control technology, intelligent image recognition technology, edge computing and big data analysis and other advanced technical means,and finally developed the digital safety interlock operation maintenance and control information system for EMU stations.

The system dynamically associates the vehicle, person and maintenance process with tools and equipment in real time, reducing the labor intensity of the operation: real-time monitoring of the operation status, automatic voice reminder of the operation steps, intelligent monitoring of the operation process, and further ensure the safety of the maintenance operation of EMU: Real-time analysis and early warning of the health status of key components involved in high-voltage electricity, timely fault diagnosis, and realize the whole process of operation data, image recording information management.

BRI began to develop the safety interlock control information system in 2007, the product has passed the technical review and scientific and technological achievements appraisal organized by the former Ministry of Railways. It achieved key technology innovation in the field of high-speed rail maintenance safety , and won 43 national patents, provincial and ministerial science and 2 technology achievement awards .
