Abstract: A dynamic monitoring method for a rebound rate of wet spraying shotcrete includes converting a set of laser points obtained from scanning to a rock wall scanning surface relative coordinate system to form an initial geometric model of the rock face, calculating the initial rock wall volume, coarse spraying and fine spraying the shotcrete and performing the three-dimensional modeling calculations, and calculating the coarse spray rebound rate and the fine spray rebound rate, thereby solving the problem that at present, the estimated idealized data does not match the actual usage data, not only it is insufficient in quantification, but also the dynamic rebound rate of the wet spraying process is not understood, in which the rebound rate is inaccurately estimated, making it difficult to guide the adjustment of the shotcrete formula and the adjustment of the spray posture and speed, and thus the goal of process optimization cannot be achieved.

Abstract: A switching converter includes a power circuit, a control circuit, and a regulation circuit. The power circuit regulates an output current through the load with at least one main switching transistor. The control circuit couples to the power circuit and controls on and off states of the at least one main switching transistor in accordance with a reference voltage received to control a minimum peak inductor current through an inductor. The regulation circuit provides the reference voltage to the control circuit and adaptively regulates the reference voltage in accordance with the input voltage and the output voltage. An effect of a duty ratio on an inductor current can be canceled out when the duty cycle changes due to fluctuations in the input and output voltages. An output current is kept approximately constant in a burst mode, thereby effectively reducing output ripple and noise.
