Problems solved by technology

[0004] In the application of the existing QCTP lane planning method, it is found that the workload of lane 6 is less than that of the other three lanes, and the idle time is the most among the four lanes of 2 / 3 / 5 / 6. Especially in the case of fewer loading and unloading operations at the terminal, the idle state of the No. 6 lane is particularly obvious, which causes a waste of resources to a certain extent and indirectly affects the operating efficiency of the AGV

Embodiment Construction

[0022] The specific implementation manners of the present application will be described in further detail below in conjunction with the accompanying drawings.

[0023] The AGV path optimization method in the automatic terminal QCTP operation proposed by this application, such as figure 2 shown, including the following steps:

[0024] Step S11: Determine the busyness of the loading and unloading ships at the automated terminal.

[0025] The busyness of loading and unloading ships represents the current workload of the automated terminal, and is defined to a set condition, such as the container loading and unloading volume per hour, or the utilization rate of bridge cranes or field cranes within a set time period, etc., in this application In the embodiment, for the QCTP lane, it is possible to determine the frequency of the AGV entering and leaving the QCTP lane.

[0026] Step S12: When the busyness of the loading and unloading ship is lower than the set condition, control t...

Abstract

The invention discloses an automated guided vehicle AGV path optimization method and system in an automated container terminal quay crane transpoint QCTP operation. The busyness degree of loading andunloading a ship of the automated container terminal is judged; when the busyness degree of loading and unloading a ship is lower than a set condition, a set lane of the QCTP lane is controlled to beswitched from an AGV interaction lane to an AGV passing lane so that the AGV can pass on the set lane; when the busyness degree of loading and unloading a ship is higher than a set condition, the setlane is kept as the AGV interaction lane. According to the automated guided vehicle AGV path optimization method and system in an automated container terminal quay crane transpoint QCTP operation in the application, a set lane is set; when the ship loading and unloading operation is busy, the set lane is used as the AGV interaction lane; when the ship loading and unloading operation is not busy, the set lane is used as the AGV interaction lane; when the ship loading and unloading operation is not busy, the set lane is switched into the AGV passing lane for use, thereby reducing the AGV operation path, improving the AGV driving degree of freedom, thereby improving the AGV operation efficiency.

Description

technical field [0001] The invention belongs to the technical field of automated wharves, and in particular relates to an AGV path optimization method and system in QCTP operations of automated wharves. Background technique [0002] The working belt in front of the container terminal refers to the area between the front line of the yard and the front line of the terminal. Its function is to serve the loading and unloading operations of the quay bridge and the operation of containers entering and leaving the yard. In the design of the container terminal, the layout of the working belt in front of the terminal is very important. The key is to determine the operating efficiency of the terminal. On the sea side of the yard of the fully automated container terminal, the automatic operation handover between the terminal and the yard is realized through the AGV (Automated Guided Vehicle, automatic guided vehicle). [0003] Existing automated container terminals usually configure s...
