| Abstract: | Aiming at the problems of poor browser drawing performance and high resource requirements under large amount of data, this paper proposed a train diagram drawing scheme based on Web technology stack. The solution covered the server operating environment, server technical architecture and front-end optimization measures. Among them, the server used microservice architecture and multithreading concurrency technology to improve the processing efficiency of operation diagram data; The front end used HTML5 Canvas graphics rendering technology to improve the rendering performance and response efficiency. The feasibility and effectiveness of the scheme are verified by the running time of key tasks such as test data loading and graphics rendering, which can provide technical reference for the optimization and improvement of railway related information systems. |
