Beidou Application丨These railway "black technologies" are actually related to Beidou?

Escort smart high-speed rail

The Beijing-Zhangjiakou High-speed Railway is the world’s first smart high-speed railway.Beidou satellite navigation systemWith other cutting-edge technologies, the 350 kilometers per hour intelligent Fuxing EMU has achieved autonomous driving for the first time in the world. The trains can automatically run between sections, automatically stop at the station, and automatically open the door when stopped.

Based on Beidou satellite and GIS technology, the Beijing-Zhangjiakou High-speed Railway has deployed a large "positioning" network that can provide intelligent services for the entire process of construction, operation, dispatch, maintenance, and emergency response.

Accurate positioning of China-Europe freight trains

Currently, China-Europe trains connect 72 cities in 21 countries. Beidou satellites can track the trajectory of China-Europe trains and their positioning is accurate to within 10 meters. Cargo owners can check the operation status of China-Europe trains at any time on the mobile client.

The distance of China-Europe trains is more than 10,000 kilometers, and they often pass through uninhabited areas. There are no mobile communication signals in those areas. When trains passed through these areas in the past, the signals were lost and there was no way to save them. Now that the Beidou positioning system is installed, the train's operating data can be recorded in real time. After the train reaches a place with mobile communication signals, it is then sent back to the China-Europe train operation service center, ensuring the integrity of the information.

Real-time monitoring of cold chain logistics

The cold storage cold chain equipment system of railway cold chain logistics adopts the Beidou positioning and data platform to realize real-time monitoring of transportation locations. The transportation data can be traced later, which greatly improves the user experience and improves transportation quality.

Issue early warning information around the clock

At the same time, Beidou helps realize all-weather, real-time monitoring of railway equipment and facilities and the environment along the line, improving railway disaster prevention and control capabilities.

Beidou infrastructure monitoring applications and single-line CTC systems based on Beidou can carry out automated high-precision monitoring of on-site work points, collect original monitoring data, and preprocess the data to achieve functions such as analysis and analysis of monitoring data and the release of early warning information.

Five key bridges and six key slopes along the Haoji Railway adopt high-precision displacement and deformation monitoring technology based on Beidou to conduct long-term monitoring of infrastructure. This can not only ensure real-time and continuity of monitoring, effectively obtain trend information, but also ensure high precision and automation, adding guarantee to line safety.

Real-time control of locomotive status

The China Locomotive Remote Monitoring and Diagnosis System (CMD System) can transmit locomotive faults, alarm information, locomotive position information and locomotive status change information to the ground system in real time through the Beidou satellite navigation system, completing the collection, processing and transmission of vehicle-to-ground and ground-to-train data.

Functional departments can promptly grasp locomotive faults, alarm information, locomotive location information and locomotive work quality status. The convenience and effectiveness of locomotive quality control by locomotive crews have been greatly improved.

Unify the clocks of all railway systems

During railway operation, if the clocks of the train equipment dispatching system and multiple signal subsystems are not synchronized, it will bring safety risks to the train operations. With the development and application of my country's Beidou system, the railway department has gradually promoted the use of the Beidou satellite navigation system as a clock synchronization source to ensure unified and accurate time.

Assisting the construction of key railway projects

The Beidou satellite positioning system has played a role that cannot be ignored in the construction of many key railway projects.

During the construction of the Wufengshan Yangtze River Bridge, the world's first high-speed railway suspension bridge, a real-time monitoring system for large-scale caisson foundation construction based on Beidou positioning technology was established to monitor caisson geometry, structural stress, mud surface elevation and other data in real time, and statistically analyze data changes and trends to provide technical support for scientific decision-making.
