The initial value of every layer of average winding circle number.For example, l/d indicates two calibrations of adjacent previous calibration signal He this calibration signal
Cable winding layer number between device, then by calculating CKIt obtains after being corrected between two calibrating installations of calibration signal at adjacent two
The average winding circle number of every layer of cable.Before the calibration signal that calibrating installation next time collects cable winding radius, utilize
CKTo estimate the cable winding layer number between this calibration signal and next time two calibrating installations of calibration signal.
Step S312, controller is according to the calculating benchmark value of revised cable winding radius, twisted and released of the cable state, amendment
Electricity is calculated in every layer of reel actual rotation circle number, the revised cable detected afterwards average winding circle number and cable size
Cable winding radius.
For example, cable winding radius can be calculated by the following formula:
Wherein, R is calculated cable winding radius, RkFor the calculating benchmark value of revised cable winding radius, ZKFor
The reel actual rotation circle number detected after amendment, CKFor every layer of revised cable average winding circle number, d is cable size.
When twisted and released of the cable state is take-up, used in formula+number；When twisted and released of the cable state is cable laying, used in formula-number.
It, can be with return step S304, to carry out continuing meter to cable winding radius after cable winding radius is calculated
It calculates and calibrates.
