Bulldozer automatic control system based on Beidou rtk technology

Abstract

The invention discloses an automatic bulldozer control system based on the Beidou RTK technology. The automatic bulldozer control system based on the Beidou RTK technology comprises a bulldozer control unit and a positioning and orienting unit, wherein the bulldozer control unit comprises a scraper knife and a scraper frame, the scraper frame is fixedly connected to the lower part of the scraper knife, a cross slope sensor is fixedly connected to the left side of the surface of the upper end of the scraper knife, a longitudinal slope sensor is fixedly connected to the right side of the scraperknife, a tilt angle sensor is fixedly connected to the middle position of the interior of the scraper frame, and a bulldozer controller is arranged in the positioning and orienting unit and connectedwith the bulldozer control unit through signal transmission. According to the bulldozer automatic control system based on the Beidou RTK technology, the Beidou RTK technology in the positioning and orienting unit is utilized, observation data of a plurality of continuously-operating Beidou base stations are utilized, gridding differential correction data are generated in real time through calculation and processing and fed back to an operator, and an automatic leveling function of a bulldozer is achieved.

Description

technical field [0001] The invention relates to the field of bulldozer control, in particular to an automatic control system for bulldozers based on Beidou RTK technology. Background technique [0002] Bulldozer is a kind of earthwork machinery that can excavate, transport and discharge rock and soil, and has a wide range of uses in open-pit mines. For example, it is used for building dumps, leveling automobile dumps, stacking scattered ore rocks, leveling work flats and construction sites, etc. It is not only used for auxiliary work, but also for main mining work. For example: stripping and mining of placer deposits, traction and boosting of scrapers and rock plows, and cooperation with other earthmoving machinery to reduce the height of stripping steps in non-transport mining methods. [0003] The most widely used automatic leveling system for bulldozers is the laser controlled mechanical automatic leveling system. It is an important means to support and improve its aut...

Problems solved by technology

[0004] When the bulldozers currently on the market are working, the height of the bulldozer is mainly recognized by the driver’s naked eyes. It is difficult to combine it with the design data. There is a high probability that the ground being pushed is too high or too low, which will affect the construction efficiency and The quality has adverse effects, and most of the currently disclosed technical solutions use laser-assisted positioning, which has poor reliability, is interfered by factors such as the environment and dust, and has poor practicability, and the bulldozer cannot automatically adjust the upper and lower positions of the scraper according to the elevation of different positions in the design, reducing the its applicability
