Beijing-zhangjia high-speed railway
The Beijing-Zhangjiakou High-Speed Railway, along with the Zhangjiakou-Dalian High-Speed Railway and the Zhangjiakou-Hohhot High-Speed Railway, was opened simultaneously. These three high-speed railway lines, centered around Zhangjiakou, radiate to Beijing, Shanxi, Hebei and Inner Mongolia provinces and municipalities, unblocking the high-speed passenger transport channels in North China.
A number of products provided by Liujie Company, such as circuit domain, packet domain, Signaling System No. 7, BMS (Base Station Air Interface Monitoring System), ATO interface monitoring system and GRIS system, are applied in it, providing a strong guarantee for the intelligent diagnosis and analysis of GSM-R network faults and the transmission of business data such as dispatching commands of the Beijing-Zhangjiakou High-Speed Railway.
Create an intelligent Beijing-Zhangjiakou
As a demonstration project of intelligent high-speed rail, the Beijing-Zhangjiakou High-Speed Railway was the first to adopt the C3+ATO train control mode and achieved the first autonomous driving of the Fuxing intelligent EMU at a speed of 350 kilometers per hour. In the autonomous driving mode, high-speed rail trains can achieve automatic control functions such as automatic departure from stations, automatic operation in sections, automatic stopping at stations, automatic door opening, and interlocking control of doors and platform doors.
In response to the new demands of C3+ATO, the management of Liujie Company selected technical experts to form a technical breakthrough team. They delved deeply into the study and research of new technologies, widely collected customer demands, and within a short period of time, achieved the monitoring of ATO data in the packet domain interface monitoring system and BMS, providing a powerful analysis tool for core network maintenance personnel in a timely manner.
The research team was working on-site and discussing solutions
At present, Gb, Gn, Gi and Um air ports have been monitored, achieving the monitoring of the two-way communication process between the on-board ATO equipment and the ground TSRS (Temporary Speed Limit Server). The interaction processes such as the on-board status, ATO operation plan and door opening and closing commands can be analyzed in detail.
Members of the technical research and development team of Liujie Company have always adhered to the concept of "creating an intelligent Beijing-Zhangjiakou Railway" during the product's research and development process. They have developed the C3 timeout intelligent analysis system, which has been successfully applied to the Beijing-Zhangjiakou High-Speed Railway. Based on years of experience in analyzing C3 timeout faults, the research team, in combination with cloud computing and big data processing technologies, has achieved automatic discovery of C3 timeout events, automatic collection of monitoring data, intelligent analysis of fault causes, precise judgment of fault types, and one-click generation of analysis reports. At present, the fault case library has covered more than 40 causes of timeout, and both the success rate of fault discovery and the accuracy rate of analysis have reached over 98%. The application of the C3 timeout intelligent analysis system has greatly reduced the workload of on-site maintenance personnel, improved the level of C3 timeout fault analysis and handling efficiency, and has received unanimous praise from on-site maintenance personnel.
Quality project
The Beijing-Zhangjiakou, Zhangjiakou-Hohhot and Zhangjiakou-Dalian high-speed railway projects lasted for more than three years. Members of the project implementation team of Liujie Company adhered to the construction concept of "building quality projects". The project leader carried out overall planning and unified management, overcoming difficulties such as the wide geographical area, large time span and high technical requirements of the projects.
During the construction process, all members of the project team adhered to the principle of "striving for excellence and pursuing perfection" of Liujie. From the very beginning of the project implementation, they maintained "high standards and strict requirements", not only demanding that the product functions meet the standards, but also that the construction quality and technological level reach a new height. Through unremitting efforts, they finally delivered a product with good performance and complete functions to the customer.
