Embodiment Construction

[0038] The bulk cargo automatic loading detection device and method of the present invention are used to measure the positional relationship between the loading mechanism and the ship and the feeding situation, that is, the relative positional relationship between the chute of the shiploading machine and the cabin and the height of the material during feeding. The ship system provides these data to complete the automatic shipment.

[0039] The present invention will be described below in combination with specific embodiments.

[0040] Install the device on the telescopic mechanism of the bulk cargo ship loader so that it can move to the top of the cabin to detect the cabin and materials. It is a more suitable choice to install it on the front end of the fixed arm. figure 2 . Define the 0-degree position of the scanning plane rotation angle of the scanner, and make the vertical axis of rotation coplanar with the scanning plane of the scanner and the axis pass through the optic...

Abstract

The present invention is a divisional application for "automatic bulk cargo shipment detection device and method", and mainly relates to a method for detecting the position of a chute by a bulk cargo automatic shipment detection device, comprising the following steps: installing the detection device on a fixed arm Rotate to the top of the cabin to be detected, determine the rotation angle of the rotating device according to the angle of the fixed arm so that the scanning plane of the scanner is perpendicular to the straight line along the shore, take the scanned data, preprocess the data, take the scanned data points within the scope of the cabin, and extract them according to the straight line The algorithm extracts the straight line formed by the scanning points on the two facades of the cabin obtained by scanning, and calculates the distance from the optical center to the two facades. The sum of the two distances is the width of the cabin, which is compared with the actual width of the cabin. The position relationship of the instrument determines the position of the chute. The invention adopts a three-dimensional detection device composed of a two-dimensional scanner and a motion control system thereof, which can effectively determine the position of the chute and detect the whole process in real time with high detection accuracy.

Description

[0001] The application of the present invention is a divisional application with an application date of June 22, 2007, an application number of 200710042453.0, and an invention title of "Automatic Shipment Detection Device and Method for Bulk Cargo". technical field [0002] The invention relates to an automatic detection device and method during the loading process of a bulk cargo terminal, which detects the positional relationship between the loading system and the ship and the material addition situation, and provides detection data for the automatic loading system. Background technique [0003] Due to the different characteristics of the goods loaded and unloaded at the dry bulk terminal, and there are many types of ships, coupled with the influence of bulk cargo dust, the operating environment is relatively harsh, and there are strict requirements for testing equipment and technology. Therefore, the current bulk cargo The degree of automation of the ship system is low, a...
