Abstract

The invention provides a truck loading automatic alignment system and method based on a multi-dimensional identification and positioning technology, and the system comprises a camera and a radar device which are disposed on a ceiling above a loading position, and are respectively used for collecting video information and radar signals after a tank car stops stably; and a central computer which is used for acquiring the video information and the radar signal, performing visual positioning based on the video information, establishing a three-dimensional model based on the radar signal, acquiring a spatial distance between a tank opening and a crane nozzle through the visual positioning and the three-dimensional model, and on the basis of the spatial distance, controlling the crane nozzle to carry out position adjustment to realize automatic alignment. The visual positioning and radar technology is used for positioning, the visual positioning is mainly used for positioning the position of a tank opening and tracking the positions of the tank opening, a loading arm and a loading nozzle of a tank car in real time, the alignment precision and the alignment efficiency are improved, and unmanned automatic alignment is achieved.

Description

technical field

[0001] The invention relates to the technical field of equipment related to liquid hazardous chemicals, in particular to an automatic alignment system and method for loading vehicles based on multi-dimensional identification and positioning technology. Background technique

[0002] At present, in the liquid dangerous chemical train loading industry, the most used is the cantilever lifting type loading crane tube. At present, most of the industry is manually operated.

[0003] The automatic alignment of the crane tube is mainly achieved by automatically moving multiple shafts of the cantilever lifting crane tube to realize the positioning of the crane mouth. The loading port of the train is open, and the crane mouth is inserted into the tank car port. The cap seal can buckle, without other complicated sealing links, has the conditions for automatic alignment. Currently, there are two main methods of positioning.

[0004] The first is the infrared sensor and ...
