摘要
基于GNSS卫星定位和姿态传感技术,研制了推土机车载推平控制装置,可实时显示推土高程、铲刀姿态以及与设计平面的高程差,以辅助引导司机调整铲刀作业;提出了参建各方远程协同的路基土石方填筑推平一体化实时监控技术,并开发了相应软件系统,可实现路基土石方填筑过程中摊铺厚度和平整性的全过程在线监控,实现“司机-管理人员-监理-业主”的一体化协同监控模式。实际工程应用表明:系统测量误差在3 cm以内,工作面平均铺筑厚度为76.5 cm,小于设计厚度,且铺筑平整性达到控制要求,有效提高了路基工程的铺筑质量,使摊铺厚度和平整性始终处于真实受控状态。
In this paper,based on the technologies of global navigation satellite system(GNSS)positioning and attitude sensing technology,a vehicle-mounted leveling control device of bulldozer was developed.The device in the driver’s cab displays the bulldozing elevation,blade attitude and elevation difference compared with the designed paving plane in real time,which can effectively guide the driver to adjust the blade operation.An integrated real-time monitoring technology was proposed for the earthwork filling and leveling of embankment with remote coordination of all parties involved in the project construction.Accordingly,the corresponding software system was also developed,which can realize the remote monitoring of pavement thickness and flatness during the whole process of embankment earthwork filling and realize the monitoring mode of“driver-manager-supervisor-owner collaboration”.The application in an actual project shows that the absolute error of system accuracy is within 3 cm,the monitored pavement thickness is 76.5 cm and less than the design thickness,and the paving flatness meets the control requirements.The system can effectively improve the quality of earthwork filling and paving of embankment,and ensure that the pavement thickness and flatness are always under real control.
