The traditional container terminal is increasingly labored to deal with the upsizing of ships, the rising of labor cost, complex weather factors and the like. The difference between the automatic container terminal and the traditional container terminal lies in that the automatic terminal comprehensively applies automatic equipment and an automatic control technology, the manual operation of the traditional container terminal is replaced to realize the autonomous operation and the intelligent control of the quayside loading and unloading, the horizontal transportation and the yard loading and unloading of the container terminal, the application of the automatic loading and unloading equipment and the intelligent control technology can obviously improve the loading and unloading efficiency of each link of the terminal, and the operation time of the quayside loading and unloading, the horizontal transportation and the yard loading and unloading of the terminal is reduced. The automatic wharf can improve the handling capacity of a port, shorten the service time of ships in the port and reduce the operation cost, and has become a necessary trend for the development of container wharfs.
The automatic wharf is a large-scale complex logistics system composed of ships, berths, shore bridges, storage yards, Automatic Guided Vehicles (AGV), track cranes and other resources, reasonably schedules and optimizes the existing loading and unloading resources of the wharf, and can effectively improve the wharf operation efficiency.
The automated dock vessel loading and unloading operation can be roughly divided into three stages. Taking an import container as an example, the first stage is that after a ship arrives at a wharf, a shore bridge starts unloading the import container from the ship; the second stage is that the AGV transports the container between the front edge of the wharf and the storage yard; the third stage is the completion of the trolley unloading and stacking of the bins from the AGV.
In the whole process, the actual loading and unloading time of the shore bridge is short, but the AGV randomly arrives under the shore bridge to wait, so that traffic jam is caused, the whole operation field area is disordered, and most of time is wasted in the waiting and queuing process. Therefore, how to ensure the smoothness and the order of the operation field area, shorten the queuing waiting time and then improve the whole operation efficiency is the key point of attention.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
The embodiment of the invention provides an automatic wharf quay crane operation method based on a double-buffer model.
When the operation is performed under the shore bridge, the AGV firstly stops to the driving buffer area available for the shore bridge, and when the horizontal buffer area of the shore bridge is idle, the AGV driving into the buffer area is allowed to drive to the idle horizontal buffer area.
After the loading and unloading operation is finally completed under the shore bridge, and the AGV is allowed to run out of the horizontal buffer area to the idle running-out buffer area when the running-out buffer area is idle.
The embodiment can ensure the smoothness and the order of the operation field area, shorten the queuing waiting time and further improve the whole operation efficiency.
Example 2
In a specific implementation level, the embodiment provides a double-buffer model, as can be seen from fig. 1, each shore bridge has its vertical buffer and horizontal buffer, and the horizontal buffer is owned by each shore bridge individually, and is essentially a piece of physical space on the working lane under the shore bridge. As shown in fig. 3, one rectangular physical parking space on 2, 3, 5, 6 lanes directly below each quay crane can be used as a horizontal buffer area of the quay crane.
The horizontal buffer area of this embodiment has a plurality ofly, has also formed redundancy mutually, has four horizontal buffer areas to mean four AGV that can berth under the bank bridge, and the bank bridge selects a certain AGV as required to carry out the loading and unloading operation.
The vertical buffer area of the embodiment is composed of a plurality of parking spaces which are well divided and located at the far sea side of the shore bridge, and the parking spaces in each vertical buffer area can be allocated to one shore bridge or a plurality of shore bridges for use.
The shore bridge is movable, and what of the vertical buffer areas can be used as an entering buffer area or an exiting buffer area of a certain shore bridge is changed along with the change of the position of the shore bridge and is also related to the operation circulation direction of the shore bridge.
Example 3
In this embodiment, on the basis of embodiment 2, taking fig. 2 as an example, if the circulation direction of the shore bridge is clockwise, all the vertical buffers on the left side of the shore bridge can be used as their driving buffers; all the vertical buffer areas on the right side of the shore bridge can be used as outgoing buffer areas.
In the embodiment, if the shore bridge works anticlockwise, all the vertical buffer areas on the right side of the shore bridge can be used as the driving buffer areas; all vertical buffers on the left side of the shore bridge can be used as outgoing buffers.
The vertical buffer and the horizontal buffer form a double buffer model in this embodiment, and the operation mode is as shown in fig. 3: an AGV that needs to work below the shore bridge needs to first drive to some empty drive buffer of the shore bridge and ask the shore bridge whether it can enter the horizontal buffer. The condition that the quay crane can enter the horizontal buffer area is that the horizontal buffer area of the quay crane has free parking spaces.
According to the method, once the horizontal buffer area of the shore bridge has the empty parking space, the AGV can drive to the horizontal buffer area of the shore bridge from the driving buffer area. And after the AGV reaches the horizontal buffer area, the shore bridge carries out corresponding ship loading and unloading operation.
After the loading and unloading operation of the shore bridge is completed, the AGV needs to run out of the horizontal buffer area to vacate positions for other AGVs. And the AGV can only exit from the horizontal buffer area when the exit buffer area of the shore bridge has a free parking space, and the AGV travels to the exit buffer area, so that the whole operation process of the double-buffer model is completed.
In conclusion, the method and the device have been verified in practical application, the method and the device can ensure the orderly operation of the AGVs, and the model of the double buffer areas ensures that the AGVs in operation can stop at the buffer parking spaces in the whole loading and unloading process of the shore bridge, thereby ensuring the continuous operation of the shore bridge, reducing congestion and providing more efficient ship loading and unloading service.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
