AUTOMATIC BULLDOZER BLADE CONTROL SYSTEM AND CONTROL METHOD

WIPO Patent Application WO/2020/119334

A1

Provided in the present invention are an automatic bulldozer blade control system and control method. The control system comprises a RTK dual-antenna module, a data receiving and resolving module, an algorithm calculating module, a display module, and a bulldozer blade control module. The RTK dual-antenna module comprises a three-axis sensor and a positioning system; the data receiving and resolving module is configured to receive and resolve data acquired by the RTK dual-antenna module; the algorithm calculating module is configured to analyze the received and resolved data; said data is then displayed by means of the display module; the bulldozer blade control module controls a bulldozer blade according to the analyzing and resolving results. The present invention is of user-centered design, and achieves accurate control to upper and lower amplitudes of a bulldozer blade during a working process of a bulldozer, thereby reducing errors in human judgment, improving the project construction quality, and improving the construction technology level.
