摘要旋挖钻机是一种取土打孔作业的施工机械，在城市高层建筑、公路、桥梁、高速铁路等的桩基工程中广泛使用。经过几十年的研发改进，目前功能日益完善。越来越多的大型、高型建筑的出现，传统的施工方式和施工机械不能够满足当今钻孔施工的条件和要求。于是，旋挖钻机这种高效、低成本、污染少的钻孔施工作业机械得到了广泛的应用，发展前景可观。
如今，与国外旋挖钻机相比，我国自主研发的旋挖钻机还有很大差距。钻杆牙嵌啮合状态检测系统也是其中一项。我国现在还没有比较好的解决方案。所以，设计出一套合理的检测系统有重要的意义。26831
本设计主要通过分析传感器接收到的信号，以此来进行判断钻杆牙嵌的啮合情况，使用单片机实现对啮合状态的检测和控制。

Rotating drill pipe embedded teeth meshing state detection system hardware design
Abstract
Rotary drilling rig is a kind of soil drilling construction machinery, widely used in pile foundation engineering of high-rise buildings, bridges, city highway, high-speed railway in the city. After several decades of research and development, the current functions are becoming more perfect. More and more large and high buildings are coming, the traditional construction methods and construction machinery can not satisfy the conditions and needs of today's construction. As a result, the drilling machine with high efficiency, low cost and less pollution, has been widely used and has considerable development prospects..
Today, compared with the foreign rotary drilling rig, China's self-developed drilling rig has a big gap comparing with other countries. The testing system for the engagement of the drill pipe teeth is one of the systems. My country has not yet better solution to solve. So it is important to design a reasonable detection system..
Through the analysis of the signal received by the sensor in this design, judging the engagement of the drill pipe teeth, the use of single-chip microcomputer to achieve the meshing state detection and control.
Keywords: rotary drilling rig; drill pipe; sensor; SCM
