Mainly suitable for sandy soil and cohesive soil, powder soil, soil layer construction, such as in piles, continuous wall, and so on the many kinds of foundation of foundation reinforcement is widely used in construction. Internal and overseas of the rotating drill there is still a big gap between the rotating drill, including domestic rotating drill rod tooth meshing state detection system and abroad there is a gap of the problem. For this problem, there is no good solution to solve. So design a rotating drill pipe embedded teeth meshing state detection system has great practical significance. Decided to adopt the design of vibration and noise measurement for rotating drill pipe embedded teeth meshing state detection. In this paper, we mainly analyze rotating drill pipe under the working condition, through the sensor measurement of vibration and noise signal, using PLC control to realize the rotating drill pipe embedded teeth meshing state detection. In this paper, the main research results are as follows: 1. The overall system design, to determine a kind of design scheme can meet the requirements of the subject. 2. The measuring element selection, select
