Example Embodiment

[0050] Example

[0051] Such as figure 1 As shown, a multi-AGV dispatch system based on a single and two-way hybrid path includes a main control system, multiple guide tracks, and multiple AGV carts. The connection point between the guide track and the guide track is the path node, figure 1 The middle guide track is a tape track, and the main control system includes a wireless receiving module, a scheduling module, and a wireless sending module.

[0052] Set an RFID tag at both ends of each guide track as the identification card, and set a different number to write into the main control system. According to the AGV driving direction, confirm that the first RFID tag on the guide track is the start identification card, and the second RFID The label is the end identification card;

[0053] The connection point between the guide track and the guide track is called the path node. Each path node is provided with an RFID tag and has the same number, which must be different from the number o...

Abstract

The invention discloses a multi-AGV dispatching system based on a unidirectional and bidirectional mixed path. Each guide track is provided with two identification cards, each path node is provided with an identification card as an execution card, RFID readers installed on AGVs read identification card information and upload the information to a master control system, the positions of the AGVs are determined according to electronic tag information, then according to task allocation, an offline path is obtained through an A* algorithm and is sent to the AGVs, the positions of the AGCs are monitored on line in real time, and conflicts among the multiple AGVs are prevented through a point-side anti-conflict algorithm.

Description

technical field [0001] The invention relates to the field of automatic conveying equipment and scheduling of industrial automation, in particular to a multi-AGV scheduling system based on a single-bidirectional mixed path. Background technique [0002] Automated Guided Vehicle (Automated Guided Vehicle) refers to a transport vehicle equipped with an automatic guidance device, capable of driving along a prescribed path, and equipped with automatic material handling functions. It is the key equipment for realizing smart workshops and promoting Industry 4.0. The AGVs system consists of multiple AGVs and the main control system scheduling software. It is a material handling system that can change the path according to the task, improving the flexibility and production efficiency of production. It is widely used in material handling places such as automobile manufacturing, airport handling, and lithium battery production. [0003] In the actual production system, the AGV schedul...
