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 invention belongs to the divisional application of a bulk cargo automatic ship loading detector and a method, and mainly relates to a method for detecting the height of materials by the bulk cargo automatic ship loading detector. The method comprises the following steps: measuring the position of the materials through a straight line extraction algorithm according to the position relationship between a chute tube and a scanner; scanning the ship cabin wall through rotating the scanner for measuring the position of the upper edge of the ship cabin through the upper end point of a straight line formed by extracted scanning points on the vertical surfaces of the cabin walls of the ship cabin; and obtaining the height of the materials through subtracting the value of the distance from the materials to the ship cabin from the depth value of the ship cabin. The invention adopts data obtained by a three-dimensional detector formed by a multiple scanner and a movement control system thereof, and effectively detects the position relationship between the materials and the upper edge of the ship cabin, so the height of the materials is calculated. The operation method is simple and effective, and can be easily realized.

Description

[0001] The application of the present invention is a divisional application with an application date of June 22, 2007, an application number of 200710042455.0, and an invention title of "Automatic Bulk Cargo Shipment Detection Device and Method". 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, and i...
