GNSS (global navigation satellite system) based intelligent flat shovel control system and method and flat shovel device

基于gnss的平地铲智能控制系统和方法及平地铲设备

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.
本发明涉及土地精细平整领域,尤其涉及一种基于GNSS的平地铲智能控制系统、控制方法及其应用该控制系统的平地铲设备;该系统包括GNSS定位单元和高度调整单元,GNSS定位单元包括GNSS基站和GNSS流动站,GNSS基站用于接收GNSS信号并计算发送差分信号,GNSS流动站用于接收来自GNSS基站的差分信号并计算发送空间信息;高度调整单元包括控制器、电液换向阀和液压缸,控制器用于接收GNSS流动站输出的空间信息并发送动作指令至电液换向阀,电液换向阀与液压缸相连接;本发明解决了激光控制平地设备存在作业范围有限、作业效率低、倾斜地面无法精确作业、大范围作业误差大、环境适应性差等问题。
