Charging method and system of four-way shuttle vehicle and control device

Abstract

The invention provides a charging method and system for a four-way shuttle vehicle and a control device. The emergency degree of charging is judged according to the electric quantity of the four-way shuttle vehicle, so that on the premise of not influencing completion of a current task, charging is conducted in a more flexible mode at a proper time, and the overall working efficiency of the three-dimensional goods shelf system is guaranteed. When the charging task is executed, the proper charging pile is locked in advance in a data interaction mode, and therefore the time consumed by the four-way shuttle vehicle for searching for the charging pile is shortened as much as possible. In order to further meet the charging requirement of the four-way shuttle vehicle needing emergency charging, the method can further request the four-way shuttle vehicle which has completed more than half of the charging task and can work normally first in the system to avoid the four-way shuttle vehicle so as to dynamically coordinate the occupation condition and the charging efficiency of the charging pile. The charging efficiency and the working efficiency of the four-way shuttle vehicle in the three-dimensional goods shelf system can be more intelligently and flexibly improved, the number of charging piles needed in a warehouse is reduced, and the cost is saved.

Description

technical field [0001] The present application relates to the field of intelligent warehouses, in particular to a charging method, system and control device for a four-way shuttle. Background technique [0002] The three-dimensional shelves of intelligent warehouses usually use four-way shuttle vehicles to realize the handling and storage of goods. The existing four-way shuttle is powered by an independent power source and needs to be recharged regularly during operation. [0003] The four-way shuttle vehicles in existing smart warehouses basically use lithium batteries, and their charge and discharge performance is greatly affected by the ambient temperature. Frequent charging is required to maintain equipment operation in harsh environments such as low temperatures. And the existing four-way shuttle vehicles are often designed to correspond one-to-one with the charging piles. When each four-way vehicle needs to be charged, it needs to return to its corresponding charging...

AI Technical Summary

Problems solved by technology

When the four-way vehicles need to be charged, they need to return to their corresponding charging piles to trigger charging. The charging process is cumbersome and difficult to schedule, so it will easily affect the turnover efficiency of the entire warehouse to retrieve and receive goods.
