Problems solved by technology

However, since WCS dispatches tasks in sequence from early to late in the scheduling of AGV tasks, there will be the following problems: the priority is uncontrollable, and the task priority cannot be intervened in special production needs; task priority and The actual business priority does not match, and the post-priority tasks may be executed first, resulting in material outages and waiting materials; too many WCS tasks are delegated to the AGV control system, and a large number of tasks are queued in the AGV control system. WCS can control the AGV tasks Low sex

Embodiment Construction

[0025] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.

[0026] The WMS warehouse management system integrates batch management, material correspondence, inventory counting, quality inspection management, virtual warehouse management, and real-time inventory management through functions such as inbound business, outbound business, warehouse allocation, inventory allocation, and virtual warehouse management. The integrated management system can effectively control and track the whole process of warehouse business logistics and cost management, and realize perfect enterprise warehouse information management. The system can perform inventory operations independently, and can be used in combination with documents and vouchers from other systems to provide more complete and comprehensive business process and financial management information. The WMS system ca...

Abstract

The invention discloses a task scheduling method, a device and a system. The method comprises steps: during a predetermined scheduling cycle, the number K of unexecuted tasks in a task buffer pool is determined; whether the number K of the unexecuted tasks is zero is judged; if the number K of the unexecuted tasks is not zero, the first M unexecuted tasks with the highest priority are selected in the task buffer pool, wherein priorities of the unexecuted tasks are updated according to the predetermined scheduling cycle, and M is associated with the number of automated guided vehicles (AGV) currently in the idle state; and the selected M unexecuted tasks are issued to an AGV control system so as to enable the AGV control system to process the received tasks. According to the method, the device and the system provided by the invention, priorities of the AGV tasks can be flexibly controlled, the AGV control system executes tasks according to priorities of the AGV tasks specified by a WCS (Warehouse Control System), and AGV tasks of each service can be ensured to be executed at the right time.

Description

technical field [0001] The invention relates to the field of automation, in particular to a task scheduling method, device and system. Background technique [0002] AGV (Automated Guided Vehicle, automatic guided vehicle) has been widely used in the field of tobacco automated logistics and warehousing at home and abroad. Among them, the AGV control system is responsible for vehicle task scheduling, intelligent obstacle avoidance, path planning, etc. It plays an important role in the tobacco automated warehousing and logistics system The application is generally a relatively independent system, and the logistics system can only send tasks to the AGV control system and obtain task status feedback information through a dedicated interface. [0003] In the prior art, the generation and scheduling methods of AGV tasks are: automatically or manually triggered by equipment to generate AGV handling tasks in WMS (Warehouse Management System, Warehouse Management System); WMS sends un...
