Novel diamond wire tension calibration method

The invention discloses a novel diamond wire tension calibration method. The method comprises the following steps: S1, adjusting actual tension parameters of a production line; s2, measuring a main vibration frequency by using a visual module; s3, according to the line body tension data set obtained in the step S1 and the vibration frequency data set obtained in the step S2, calculating a proportional parameter of tension and vibration frequency square in each set; s4, performing weighted average on the proportional parameters of the n groups of data to obtain calibration parameters; and S5, calculating an actual tension value through the calibration parameters. The physical relation formula of the vibration frequency, the length, the mass density and the tension of the string is utilized, the parameters of the length and the mass density are calibrated and cured in advance, so that the actual line body tension is mapped under the condition that the vibration frequency is detected, the tension detection preci
