To solve the problems existing in global ports such as the poor connection of multimodal transport and conflict of port city development，we adopt the multi-system integration method based on terminal production scheduling platform to deal with the multi-source information fusion，such as multi-software architecture，multi-interface，and multi-data format. For the precise positioning of various equipment in the intelligent overhead rail system under the complex wharf environment，we adopt the method of multi-positioning technology integration in complex scenes. Combining the air rail transport technology with the terminal business demand，we open the last kilometer of sea-railway intermodal transport through three-dimensional transportation mode，which provides a solution for the poor connection of multimodal transport and the traffic conflict between ports and cities，and provides a reference for the application of air-rail in other ports and industries to deal with the ground traffic congestion.
