摘　　要：该仪器通过单片机和电子罗盘、旋转编码器等,实时检测非开挖竣工管道各测点的方位角、俯仰角和测点间距,应用上位机和LabVIEW开发平台,按最小曲率法的轨迹计算模型,实时重构管道轨迹,并显示、存储。从而为管道的竣工验收提供质量评判的量化指标。仪器的地面模拟实验表明:在有地磁异常影响时,长度方向误差为0.5%,深度方向误差为1.0%,水平方向误差为1.9%。仪器的现场实验表明:在无地磁异常影响时,其各向最大偏差小于20 cm,有实用价值。To survey trenchless completion pipeline trajectory,this paper developed an instrument to get the azimuth,pitch and point spacing in real-time through electronic compass,rotary encoder and microcontroller unit,and realized the trajectory reconstruction,point＇s coordinate displaying and storage by processing the signal successively on supervisory computer and LabVIEW8.5 platform. Simulation experiment in ground indicated that if magnetic anomaly existing,the detector＇ accuracy in pipe length direction was 0.5%,in depth direction＇s was 1.0%,in horizontal direction＇s was 1.9%.Field experiment indicated that its maximum deviation in any direction is within 20 cm,if no magnetic anomaly existing,it has practical usevalue.
