Embodiment 1

[0049] The process of loading and unloading goods at the container terminal is: firstly, the container is transferred from the freighter to the AGV by the bridge crane, then the AGV transports the container to the yard, and then the container is stacked to the designated location of the yard by the rail crane, which is limited by the number of AGVs. If Unreasonable scheduling arrangement will lead to long waiting time of AGV and low transportation efficiency. In order to solve the above problems, this embodiment proposes an AGV scheduling method based on a time estimation model, such as figure 1 shown, including the following steps:

[0050]The static estimation step is to estimate the static estimation value of the operation efficiency of the bridge crane and the rail crane respectively; respectively estimate the static estimation time of the container in each operation stage, including: the static estimation time of the interaction phase between the AGV and the bridge crane a...

Abstract

The invention discloses an AGV scheduling method based on a time estimation model, and the method comprises the following steps: a static estimation step: respectively estimating the static estimation values of the operation efficiency of a bridge crane and a rail crane; respectively estimating static estimation time of the container in each operation stage; a dynamic estimation step: respectively estimating dynamic estimation values of the operation efficiency of the bridge crane and the rail crane; respectively estimating the dynamic estimation time of the container in each operation stage; according to the static estimation time and the dynamic estimation time of each operation stage, calculating the final estimation time and the total operation estimation time of the container in each operation stage; and generating an AGV operation scheduling instruction according to the final estimation time of the container in each operation stage and the total operation estimation time. According to the AGV scheduling method based on the time estimation model, the AGV scheduling is more reasonable in combination with the estimated time, the AGV waiting time is reduced, the AGV no-load operation time and distance are shortened, and the AGV transportation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of automatic wharf transportation, and in particular relates to an AGV scheduling method based on a time prediction model. 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 quayside bridge and the operation of containers entering and leaving the yard. Manual driving is usually used in manual terminals and semi-automatic terminals. Inner set card. In recent years, with the continuous increase of labor costs, more and more terminals have changed their horizontal transportation equipment from internal collection trucks to AGV (Automated Guided Vehicle, automatic guided vehicle). The use of AGV has greatly improved production efficiency and saved costs. . [0003] On the sea side of the fully automated container terminal, ...
