港口货运空轨列车防护地面超高集卡系统设计OA

In port freight collection and distribution systems,suspended monorail trains operating in fully automatic mode and ground container trucks with a height of more than 6 meters(referred to as"over-height container truck")use shared-space areas on their running paths,causing frequent conflicts.To address this,this paper proposes an over-height container truck protection system for sky trains.An initial analysis was conducted,investigating timing and characteristics of shared-space area occupations by both fully automated sky trains and operating over-height container trucks.Based on detection of their operating positions,an automatic protection system was designed.It enables time division multiplexed access to these shared-space areas,ensuring operational safety for trains and trucks.Field tests and applications indicate that in scenarios where the shared-space areas are unoccupied by monorail trains,this automatic protection system reduces the average passage time of over-height container trucks through the restricted areas by about 32.8%,compared with manual protection operations.The system effectively improves operational safety and transport efficiency for both trains and trucks and contributes to a higher utilization rate of port resources.
