Automatic operation monitoring method and system for unmanned bulldozer
The invention discloses an automatic operation monitoring method for an unmanned bulldozer, and the method comprises the steps: installing an oil cylinder pressure sensor and a stroke sensor at a pressure measurement point of each oil cylinder of a bulldozer scraper knife, installing a pin shaft force measurement device at a proper position of each stress rod piece of the bulldozer scraper knife, and installing a receiving device of a satellite navigation device on the bulldozer. The engine rotating speed sensor collects engine rotating speed information to serve as real-time input data of engine information, a logical algorithm process is edited through the data, and automatic operation control over the unmanned bulldozer is achieved according to the logical algorithm process. The system can automatically judge whether the unmanned bulldozer is in an overload range or not according to a logical algorithm, if not, the rotating speed of an engine of the bulldozer under large-load full-load operation can be automatically adjusted, the operation efficiency of the bulldozer is improved, and the working efficiency of the bulldozer is improved. The problems of insufficient load, overload operation identification and logic control adjustment in overload application of an unmanned bulldozer at present can be solved.
本发明公开了一种无人驾驶推土机自动作业监控方法，在推土机铲刀的各油缸的压力测点安装油缸压力传感器及行程传感器，在推土机铲刀的各受力杆件的合适位置安装销轴力测量装置，推土机上安装卫星导航装置的接收装置，发动机转速传感器采集发动机转速信息，作为发动机信息的实时输入数据，通过上述数据编辑逻辑算法流程，根据逻辑算法流程，实现无人驾驶推土机自动化作业控制。本发明系统可根据逻辑算法，自动判定无人驾驶推土机是否处于过载范围，如未过载，则可自动调节至推土机发动机大负荷满载作业下的转速，提高推土机作业效率，能够解决目前无人驾驶推土机应用过载中的负载不足及过载作业的识别及逻辑控制调整的问题。
