Abstract

The invention discloses a positioning algorithm of a lifting appliance precise positioning system. At the moment T, a laser distance measuring sensor measures the vertical distance between a lifting appliance body and the top surface of a container needing lifting at the moment T, namely the length of a line segment EF, and the length of the line segment EF is the distance that the lifting appliance body needs to move downwards and vertically at the moment T; four ultrasonic receiving modules receive ultrasonic wave transmitted by an ultrasonic transmitting module before correspondingly, the respective received time intervals tA, tB, tC and tD of the four ultrasonic receiving modules are calculated, the length of a line segment EA, the length of a line segment EB, the length of a line segment EC and the length of a line segment ED are calculated, the length of a line segment OF is calculated, and the length of the line segment OF is the distance that the lifting appliance body needs tomove horizontally at the moment T. According to the above process, continuity and rapidness of automatically performing crude positioning, fine positioning and precise positioning by the lifting appliance are realized, and the lifting precision and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of logistics transportation, in particular to a positioning algorithm of a spreader precise positioning system. Background technique [0002] The greatest success of the container lies in the standardization of its products and the entire transportation system established thereby. It is indeed worthy of the standardization of a behemoth with a load of tens of tons, and based on this, the gradual realization of a global logistics system for ships, ports, routes, highways, transfer stations, bridges, tunnels, and multimodal transport. It is called one of the great miracles created by human beings in history. [0003] With the increasing role of containers in logistics. There are cranes for containers at the wharf for lifting and transporting containers. The hook of the crane is hung with a container special spreader that can quickly lift the container, that is, the fixed spreader (also called the integral s...
