Abstract: Aiming at common problems in railway logistics yards, including difficult site addressing, low vehicle positioning efficiency, and disconnection between navigation and on-site operation management, this paper took improving the quality and efficiency of logistics services as the core objective, designed a navigation system for railway logistics yards, and described the system architecture, operation flow and key technologies. The system achieves functions such as navigation management, precise vehicle guidance, operation path optimization, and yard resource coordination. The research results effectively improve the operation efficiency, traffic safety and standardization level of logistics services in railway logistics yards, and provide support for the digital and intelligent upgrading of railway logistics yards.
