Description

Efficient operation container port land area system and operation method thereof

Technical Field

The invention belongs to the technical field of container port logistics, and particularly relates to a container port land area system with high operation efficiency and an operation method thereof.

Background

The container port is a junction station of the amphibious transportation, is a buffer ground for the container cargo when the transportation mode is switched, and is also a junction point of the cargo. Thus, container ports play an important role in the overall container transportation process. The container port is generally composed of a harbor pool, an anchor ground, a harbor channel, a berth and other water area parts, a freight station, a yard, a wharf front edge, an office living area and other land area parts.

The front edge of the wharf refers to the area from the quay line to the yard, and a plurality of quay container loading bridges (called quay bridges for short) are generally arranged. In the case of container port land area arrangements, there are generally two arrangements in the prior art for the quay front area below the quay bridge.

First, for conventional quays, especially small quays, a truck aisle is typically provided below the quay, for the passage of container trucks (simply called pallets). The quay crane operator operates the quay crane to discharge the container from the ship, drop it onto the pallet, and transport the container by the pallet to a rear yard or directly out to the customer.

Secondly, for modern docks, especially large docks, which operate automatically or semi-automatically, a container tractor channel is generally arranged below the quay bridge, on which a horizontal transport vehicle, such as an automatic guided transport vehicle (AGV), an artificial intelligent transport robot (ART), an unmanned container transport vehicle (AIGT), an intelligent mobile transport flatbed (IMV), etc., is operated, for transporting the container unloaded from the quay bridge to a rear yard.

However, for small wharfs, on the one hand, the wharf space is small, and the area requirements of the collector card on the operation site are high, so that the availability of wharf space is greatly reduced due to the existence of a truck passage. On the other hand, when there are multiple cards on the truck aisle, the cards need to be avoided and waited for, which also greatly reduces the loading and unloading efficiency of the container. For modern wharfs of automatic or semi-automatic operation, the congestion problem among a plurality of transport vehicles easily occurs when the horizontal transport vehicle is transported, and the more the transport vehicles are, the greater the congestion probability is, which greatly influences the loading and unloading efficiency of containers; on the other hand, in order to reduce the occurrence of congestion and the waiting time caused by the congestion, the container tractor channel needs to be widened, the number and the precision of positioning sensors of the transport vehicle are increased, and an algorithm for optimizing the automatic navigation driving is optimized, so that the cost of the automatic operation system of the whole horizontal transport vehicle is greatly increased.
