旋挖钻机钻杆牙嵌啮合状态检测系统硬件设计
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
