Laser container finding method, hoisting system, controller and storage medium

Abstract

The embodiment of the invention relates to the technical field of operation and maintenance control, and discloses a laser container finding method, a hoisting system, a controller and a storage medium. The laser container finding method provided by the invention is applied to the controller in the hoisting system. The hoisting system comprises a hoisting device and the controller; eight laser devices are arranged on the periphery of the hoisting device; four laser devices in the eight laser devices are distributed on four end points of a pair of opposite sides of the hoisting device; the other four laser devices are distributed on the other pair of opposite sides of the hoisting device in pairs; and the eight laser devices are respectively in communication connection with the controller.The method comprises the following steps of obtaining laser emission distance values measured by the eight laser devices; and controlling the lifting device to move according to the laser emission distance values reported by the eight laser devices until the reported laser emission distance values conform to the preset conditions. The high-precision container finding can be realized at low cost.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of operation and maintenance control, in particular to a laser box finding method, a lifting system, a controller and a storage medium. Background technique [0002] With the development of automation technology, the stand-alone functions of dock cranes are becoming more and more intelligent, and unmanned and automated cranes are being used more and more widely. Most of the common cranes travel to a fixed position, and then the master driver carries out the container handling operation. The container stacking operation at the wharf requires that the relative position error between the two boxes and the overall position error of the stacked container must be within the specified range. The process of container grabbing and stacking requires a high degree of proficiency in the driver’s control. It is also a difficulty in realizing terminal automation. In order to solve this problem,...
