Embodiment 1

[0025] see figure 1 , the AGV traffic control scheduling method of the present invention includes a central control center and several AGVs, the central control center is preferably a PC terminal, the central control center is connected to the AGV through wireless communication, and several route points are arranged on the route network of the AGV, Several path points are connected by set one-way or two-way edges to establish a path map model. Select the starting point and target point of AGV driving from several path points, and the AGV can reach the target point via other path points from the starting point. Or directly arrive at the target point. When the central control center detects in the route map that more than two AGVs form a circular wait in the network route map, the central control center uses the following steps to unlock the circular wait.

[0026] a. The central control center judges each AGV. If two or more AGVs are waiting for each other, they are judged to b...

Embodiment 2

[0038] In the storage device of the present invention, the storage device stores multiple execution instructions, and when the central control center detects that more than two AGVs are waiting in a loop in the network path diagram, the execution instructions are used for the central control center to load and perform the following operations:

[0039] a. The central control center judges each AGV. If two or more AGVs are waiting for each other, they are judged to be AGVs in a deadlock cycle. The AGVs blocked by the AGVs in the deadlock cycle are AGVs outside the deadlock cycle. Specifically, this step includes, a1. The central control center searches for the AGVs waiting in front of each AGV in the waiting cycle; a2. Continues to search for the AGVs waiting in front of them; a3. Repeats step a2 until the repeated AGVs are found Or when the searched target is its own AGV, stop the search. If the searched target is its own AGV, it is judged that the AGV in the cycle waiting is t...

Abstract

The invention discloses a scheduling method for AGV traffic control and a storage device. According to the application of the scheduling method, when AGVs have traffic jam, a center control center detects that two or more AGVs form a cycle in a network path diagram for waiting, by planning a driving path of the AGVs in the deadlock cycle or AGVs waiting beyond the deadlock cycle again, deadlock cycle leading to traffic jam is unlocked, and more AGVs are prevented from being jammed.

Description

technical field [0001] The invention belongs to the technical field of AGV traffic control, and in particular relates to an AGV traffic control scheduling method and a storage device. Background technique [0002] With the increase of labor costs and the demand for industrial automation transportation, AGV has gradually become an important transportation tool in enterprises. For AGVs that can operate in multiple directions, they have high flexibility and high operation and transportation efficiency, and they have also been compared in storage systems. A wide range of applications, by introducing multiple AGVs to move materials or goods in the storage space, abandoning the traditional manual cargo transportation, realizing unmanned automatic storage and handling, and easy to use. However, the introduction of multiple AGVs into the storage space also increases the complexity of traffic control and traffic jams. When there is a traffic jam between multiple AGVs, AGV deadlock wi...
