Under this background, using drilling speed to represent the properties of rock (rock mass) has become a hot topic today. There is a relationship between the drilling speed of the drilling machine and the properties of the rock as follows: good lithology quality, slow drilling speed; poor lithology quality, fast drilling speed; at places where the rock quality has obvious differences, the drilling speed will change abruptly.

[0005] However, when using the above-mentioned patent, in the external environment, there are a large number of light sources containing infrared light such as strong sunlight, and these interference sources will affect the accuracy of the detection result. In addition, the ground or drill pipe at the test site is often a black object, which has a strong absorption effect on infrared, resulting in insufficient infrared reflection, which causes a large error in the measurement result and seriously affects the accurate analysis and judgment of the shallow surface rock.
