Embodiment Construction

[0081] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0082] Such as figure 1 As shown, a GNSS-based ground shovel intelligent control system, the system includes a GNSS positioning unit 100 and a height adjustment unit 200, wherein the GNSS positioning unit 100 utilizes GNSS positioning technology to monitor the three-dimensional information of the ground in real time, and is similar to the GNSS positioning unit 100 The connected height adjustment unit 200 compares this information with the preset ground leveling requirements, and generates an action command accordingly, and then the height adjustment unit 200 drives the shovel body mechanism 300 to execute the action command, and adjusts the height of the shovel body mechan...

Abstract

The invention relates to the field of fine flattening of lands, in particular to a GNSS (global navigation satellite system) based intelligent flat shovel control system and method and a flat shovel device applying the control system. The system comprises a GNSS positioning unit and a height adjusting unit, wherein the GNSS positioning unit comprises a GNSS base station and a GNSS moving station. The GNSS base station is used for receiving GNSS signals and calculating and transmitting differential signals. The GNSS moving station is used for receiving the differential signals from the GNSS base station and calculating and transmitting spatial information. The height adjusting unit comprises a controller, an electro-hydraulic directional control valve and a hydraulic cylinder. The controller is used for receiving the spatial information output by the GNSS moving station and transmitting action commands to the electro-hydraulic directional control valve connected with the hydraulic cylinder. By the GNSS based intelligent flat shovel control system and method, the problems about limited operation range, low operation efficiency, failure in accurate operation on slopes, large error in large-range operation, poor environmental adaptability and the like of laser control on the flat shovel device are solved.

Description

technical field [0001] The invention relates to the field of fine leveling of land, in particular to a GNSS-based intelligent control system for a ground shovel, a control method and a leveling shovel device using the control system. Background technique [0002] With the development of modern agriculture, higher requirements have been put forward for farmland land consolidation. Land consolidation and construction should be developed towards refinement. Guided by the overall planning of land use, overall consideration should be given to the comprehensive benefits of economy, society and ecology to improve the quality of farmland. In terms of land consolidation quality planning, it promotes a virtuous cycle of the ecosystem. Realizing fine land consolidation is the premise and key to realizing water-saving irrigation, and it is also a necessary means to organize high-quality cultivated land. [0003] Land leveling is the final link of land consolidation, and the quality of ...
