In the information age, rail transit equipment is constantly innovative, and high-speed trains have better performance. Advanced network operation technology, such as automatic train control and real-time monitoring system, needs supporting information visualization technology to transform a large amount of information generated during train operation into easy-to-understand visual information, so as to improve the safety and efficiency of train operation and improve the level of passenger service. Information visualization technology is very important in the rail transit equipment system. Therefore, this paper makes a comprehensive analysis of the visualization technology that can be applied in the rail transit equipment, puts forward the visualization elements applicable to the rail transit field, prepares the visualization chart library of the information of rail transit equipment and carries out the information visualization design of the rail transit equipment system. Hope enough for the relevant personnel to provide basic reference suggestions.
