Abstract: The high-speed railway network in China is becoming increasingly perfect, and the railway department's requirements for the efficiency and quality of high-speed railway dispatching plan compilation are increasing. In order to adapt to the development needs of high-speed railway network operation and solve the current problems of decentralized compilation of high-speed railway dispatching plans, independent operation of each position, and data dispersion between systems, this paper proposed to build a high-speed railway plan compilation application system suitable for intelligent comprehensive dispatching. The paper analyzed the business process of high-speed railway plan compilation, and based on this, designed the overall architecture, network architecture, data architecture, and functions of the system, implemented a high-speed railway plan compilation mode of centralized data deployment, collaborative office work, and timely response to passenger flow needs. This system provides technical support for refined command and intelligent decision-making of high-speed railway dispatching.
