Crane operation assistance system

摘要

A crane operation assistance system includes: a scanning-type distance meter capable of measuring a distance and an angle between the distance meter and an object under a range of movement of a movable body that can hoist a container and move in a horizontal direction; and object height distribution data making means for making, based on the information measured by the distance meter, object height distribution data that is data indicating a distribution of heights of objects under the range of movement of the movable body. If a blind spot for the distance meter has occurred, the object height distribution data making means revises data of object heights in the zone of the blind spot based on data of an object height at a point that is farthest from the distance meter in a imaginary containers presence zone having an overlap with the zone of the blind spot.

1. A crane operation assistance system for assisting operation of a crane including a movable body capable of hoisting a container and moving in a horizontal direction, the system comprising:
a scanning-type distance meter mounted on the movable body, the scanning-type distance meter being capable of measuring a distance and an angle between the scanning-type distance meter and an object under a range of movement of the movable body; and a controller that is programmed to: lower the container into an imaginary containers presence zone that includes a container storage space able to accommodate the container; make, based on information measured by the scanning-type distance meter, object height distribution data that is data indicating a distribution of heights of objects under the range of movement of the movable body; and revise, if a blind spot for the scanning-type distance meter has occurred in the made object height distribution data, data of object heights in a zone of the blind spot, wherein the revised data of the object heights is based on data of an object height at a point that is farthest from the scanning-type distance meter in the imaginary containers presence zone having an overlap with the zone of the blind spot.
