A method of determining the average slope of the elementary area in the field and for its implementation profiler

1. A method for determining the mean deviation of the elementary area in field conditions, comprising measuring the surface profile using a profiler, characterized in that, in order to simplify the process and improve the accuracy of determining the average elementary area slope determined profile profilograph surface circumferentially delimiting elementary area, build scan of this profile and polynomial trendline fourth power under this scan, determine the value of the top point of the polynomial, which conventionally corresponds to 1 80 ° position of the roller relative to the zero mark, on which you can analytically calculate the average slope of the elementary area in the field usloviyah.2. Profiler to determine the average elementary area bias field, comprising a frame with three legs, characterized in that, in order to simplify the process and improve the accuracy of determining the average elementary area bias field pivotally-Lockable axle is provided with roller bearing, on which the telescopic shoulder with fixed perpendicularly on the end of the bar, in the bottom of which is attached to the leash in the form of a parallelogram, the roller mechanism and the vertical movement sensing roller, with toyaschy of the displacement transducer, a rigid tape with a longitudinal frame disposed horizontally to transmit only the vertical movement of the roller guide fixed to the bracket and displacement sensor slide on the disk surface is rigidly fixed to the hinged-lockable axle, and the information from position sensors is transmitted to the computer through radio frequency
