摘　　要：为保障钻井工作科学有效进行,研究了一套基于LabVIEW大钩高程监控系统。该系统能准确测量大钩高程,实时显示孔深、大钩高程、机上余尺、机械钻速和钻具长度等参数。大钩移动过程中可以实现参数超限自动声光报警功能,防止游动滑车上升时与天车撞顶事故发生,并能显示大钩与二层台的相对位置,便于挂卸提引器。在天车的定滑轮上安装磁钢,大钩移动时,与磁钢对应位置的双通道霍尔传感器产生脉冲信号,经过数显表微处理转换,再通过RS485串口通信连接PC机,利用LabVIEW平台实现数据的采集、分析、显示和存储等工作。实践证明,该系统安装简便,测试精度高,实用性强,可广泛应用于立轴钻机、转盘钻机、全液压钻机等不同类型钻机。To ensure the scientific and effective drilling operation, a hook position monitoring system is designed based on LabVIEW.It can measure the hook position, provide real time display of hole depth, remanent distance of drilling rig, penetration rate and drill length.Meanwhile, a double channel hall sensors is installed on the crown block to detect the pulse signals, through the transformation of micro programming conversion by the digital display meter, serial port commu-nication connecting PC and Labview platform, the data acquisition, analysis, presentation and storage are realized.The practice proves that this system has the advantages of convenient installation, high test precision and strong practicability and can be widely applied to the vertical drilling machine, rotary drilling rig and hydraulic drilling rig.
