Description

technical field [0001] The invention relates to the technical field of signal transmission, and relates to a data multi-stage processing device for cutting data. Background technique [0002] The in-situ rock drilling shearing instrument is a test device for measuring the internal friction angle φ and cohesion c of the rock on site. It belongs to a kind of rock in-situ test test; It is lowered to a certain depth, and oil pressure is applied to press the rock drilling shear head into the wall of the drilling hole to form a normal stress, and then the steel rod connected with the shear plate is pulled to apply shear stress, so that the embedded rock drilling is sheared. The rock mass of the head has direct shear failure, and the shear strength of the rock mass is calculated by reading the normal stress corresponding to the maximum shear stress at the time of failure of the instrument panel. [0003] The test data of the measurement system is transmitted to the shearing instru...
