Embodiment Construction

[0033] see Figure 2 to Figure 8 , the present invention realizes the control method of the AGV path without signal lights, is to process the entire terminal automation area into a traffic area without signal lights control, so as to realize the command of vehicles without signal lights. Such as figure 2 As shown, there are many routes for the AGV from the starting point O1 to the ending point O2, but if signal lights are set at nodes 1, 2, and 3 to force the AGV to travel in a fixed direction, then the route of the AGV from the starting point O1 to the ending point O2 There is only one, that is, the setting of the signal indicator light directly affects the generation of the final driving route of the AGV. But in the AGV control algorithm of the present invention, these signal indicator lights can be processed as environmental conditions (that is, there is no signal light command). by figure 2 Taking node 1 as an example, the coordinates of node 1 can be used as a constr...

Abstract

The invention provides a method for realizing signal-lamp-free AGV path control. A traffic area is divided into a driving area and a loading and unloading area, and the traffic lanes of the driving area and the traffic lanes of the loading and unloading area are one-way lanes. The traffic lanes of the driving area comprise a lane to a shore bridge, a lane to a storage yard and a lane back to a repair area, wherein the directions of the lane to the storage yard and the lane back to the repair area are opposite to the direction of the lane to the shore bridge. The loading and unloading area comprises working lanes and crossing lanes, wherein there is one crossing lane on one side of any working lane, and there is one adjacent working lane on the other side of any working lane. According to the method, through the setting of the one-way trip lane, the return lane, the working lanes, the crossing lanes and the like, the complexity of the AGV path network is greatly reduced, transport AGVsgoing into or out of the storage yard are not prone to collision, congestion and jam, and the working efficiency is improved.

Description

technical field [0001] The invention relates to an AGV (Automated Guided Vehicle, automatic guided vehicle) path realization method, which is suitable for storage yards, docks and other places. Background technique [0002] The traditional traffic jam is mainly due to the complex road conditions and concentrated traffic flow at the intersection of the yard. [0003] The storage yard is a place for storing containers, responsible for the handover and storage of import and export containers. As a buffer zone for the import and export of containers, the yard ensures the continuity and efficiency of container loading and unloading operations. According to the current domestic container terminal operation method, when an imported ship docks at the berth, in order to shorten the unloading time, the idle quay cranes are moved together through the rails, and only a certain safety distance between the quay cranes is required. That's it. Although this improves the loading and unloa...
