In response to the lack of design standards and insufficient research on digital infrastructure for automated container terminals,this study adopts an engineering case analysis method to systematically summarize the design principles and implementation strategies of data centers,5G private networks,and F5G optical networks.It is concluded that data centers should follow the principles of safety,reliability,greenness and energy efficiency.5G private networks need to meet high reliability requirements to ensure key applications such as autonomous driving,while F5G optical networks need to meet high bandwidth and stability requirements.The design scheme and principles proposed in this article can provide theoretical support and technical guidance for the construction of smart ports,which is of great significance for promoting the digital transformation of the port industry.
