Embodiment Construction

[0032] A time-window-based AGV intelligent scheduling method realizes automatic avoidance when multiple AGVs are running simultaneously in the same area by pre-judging the status of running path nodes, pre-occupying idle nodes based on time windows and automatically avoiding occupied nodes. Improve operational efficiency and operational safety, such as figure 1 As shown, the specific steps are:

[0033] (1) According to the characteristics of the site environment and the requirements of dispatching tasks, establish a laser navigation coordinate system, construct a site map, and plan to construct the operating path nodes of the automatic guided transport vehicle AGV, and calculate the coordinates and types of each operating path node in the laser navigation coordinate system , positioning mode and path direction are determined, and the site map file is generated according to the above-mentioned site map information; a matrix code is set at the position where visual navigation a...

Abstract

The invention discloses an AGV intelligent scheduling method based on a time window. Path pre-occupation is carried out by adopting a time window calculation method under a high priority and time priority principle; time-sharing use and automatic avoidance of multiple AGVs on the same road section are realized; flexible setting of each path node and priority classification and sorting of tasks arecarried out according to virtual mapping of a field operation environment. The method is advantaged in that problems that multiple AGVs on a production site are difficult to operate at the same time,and the conditions of insufficient path capacity, multi-vehicle conflict, path intersection, loop deadlock and the like are likely to occur are solved, and operation efficiency and operation safety are effectively improved.

Description

technical field [0001] The invention relates to an AGV intelligent scheduling method based on a time window, and belongs to the technical field of intelligent scheduling. Background technique [0002] AGV is an important part of the flexible manufacturing system. It plays an indispensable and important role in the automation and intelligence of the production process, especially in discrete manufacturing enterprises. Manufacturing automation, processing, assembly, etc. AGV is an important tool to improve production and manufacturing efficiency. It is conducive to the realization of intelligent and modern manufacturing of factories, workshops, production lines, etc., especially in industrial technologies such as processing and transportation. The AGV scheduling system completes the management of multiple AGVs, path planning, task allocation, status monitoring, etc. The performance of the scheduling system directly affects the transfer efficiency, thereby affecting production...
