System Overview
The vehicle-to-ground wireless transmission system transmits the operational status information and fault information of rail transit vehicles (moving cars, subways, trams, etc.) to the operation monitoring center in real time, and analyzes and processes the information in real time to achieve full tracking of vehicle operating conditions. Fault alarm warning. Through the accumulation of data, a complete vehicle operation, maintenance, and fault history data center is gradually established. Through statistical analysis and data mining, decision support for vehicle maintenance and quick service is provided, and vehicle maintenance informationization and modernization are effectively realized.

Ground subsystem
[Based on B/S architecture]
By accessing the application software through WEB, there is no need to install the client, and users with permission can log in to the system through the browser on any computer. In an emergency, many experts consult the fault, and the information obtained by each person is consistent through the background to avoid the wrong transmission of information.
[Friendly User Experience]
The application software is simple to operate, supports multiple visual views, real-time graphical display, supports a variety of statistical analysis functions, and visualizes in the form of charts and the like.
[Powerful background processing capability]
It can receive multiple concurrent data transmissions from multiple vehicle terminals and distribute them in time. Based on Hadoop's big data storage and analysis platform, seamless expansion, automatic backup, and parallel computing of multiple computer nodes.
