Specifically, if the rotational speed value of the drill bit drops suddenly and the pressure value between the drill bit and the formation rises suddenly and the real-time depth value of the borehole stagnates, it is determined that one or more of the following faults occur: drill bit tooth wear, encountering hard rock or foreign objects, insufficient hydraulic motor torque. If the inclination angle value of the drill pipe changes suddenly and the real-time depth value of the borehole is abnormal and the pressure value at the concrete pouring site is zero, it is determined that one or more of the following faults occur: drill pipe fatigue fracture, torque overrun. If the volume value of the poured concrete increases abnormally and the pressure value at the concrete pouring site fluctuates and the real-time depth value of the borehole rebounds, it is determined that one or more of the following faults occur: too fast drilling speed, failure to timely protect the wall of the loose formation. If the pressure value at the concrete pouring site rises suddenly and the volume value of the poured concrete is insufficient, it is determined that one or more of the following faults occur: blockage of the concrete pouring conduit, damage to the concrete pouring conduit seal ring. If the pressure value between the drill bit and the formation is unstable and the rotational speed value of the drill bit fluctuates and the inclination angle value of the drill pipe drifts, it is determined that one or more of the following faults occur: hydraulic oil pollution or leakage, pump / valve group failure, and the fault determination result is output to the display terminal 130. The display terminal 130 receives the fault determination result and displays it.

[0054] As Figure 15As shown in the figure, the present application also provides a data recording system, including the above data recorder 100 and a host computer 200; the host computer 200 is connected to the second end of the data recorder 110 of the data recorder 100; the host computer 200 is configured to obtain and output a monitoring report based on the rotational speed value of the drill bit, the inclination angle value of the drill pipe, the pressure value between the drill bit and the formation, the real-time depth value of the borehole, the volume value of the concrete already poured, and the pressure value of the concrete pouring site stored in the data recorder 110 within a preset time period.

[0055] In this embodiment, the preset time period is a pre-set time period. The host computer 200 obtains and outputs a monitoring report (such as in the form of a document or a table) based on the rotational speed value of the drill bit, the inclination angle value of the drill pipe, the pressure value between the drill bit and the formation, the real-time depth value of the borehole, the volume value of the concrete already poured, and the pressure value of the concrete pouring site stored in the data recorder 110 within the preset time period, enabling the user to understand the working conditions of the auger drill within the preset time period. In this embodiment, the host computer 200 can train a fault analysis model (such as a neural network model) with a large amount of historical data of the rotational speed value of the drill bit, the inclination angle value of the drill pipe, the pressure value between the drill bit and the formation, the real-time depth value of the borehole, the volume value of the concrete already poured, and the pressure value of the concrete pouring site to obtain a trained fault analysis model. When the auger drill fails, the real-time data collected by each sensor is input into the fault analysis model to obtain and display the fault analysis result of the auger drill. The host computer 200 can also train a fault prediction model (such as a neural network model) with a large amount of historical data of the rotational speed value of the drill bit, the inclination angle value of the drill pipe, the pressure value between the drill bit and the formation, the real-time depth value of the borehole, the volume value of the concrete already poured, and the pressure value of the concrete pouring site to obtain a trained fault prediction model, and then input the real-time data collected by each sensor during the operation of the auger drill into the fault prediction model to obtain and display the fault prediction result of the auger drill.
