Encoder for detecting the rotating cycle of wire spool, and then obtains remaining cable ring number on wire spool；
PLC controller adjusts frequency control for receiving encoder information and control parameter information, and to frequency converter output torque
Signal and reception frequency conversion feedback signal.
The variable-frequency motor drives wire spool by reduction gearbox.
The output par, c of the PLC controller is additionally coupled to the control circuit of brake, and brake is for brake variable-frequency electricity
Machine.
Cable lifting system constant-tension control method of the invention promotes constant tension control device based on above-mentioned cable, in ship
Oceangoing ship powering phase or power supply terminate the winding cable stage, and PLC controller is joined according to the encoder information of acquisition and the control of input
Number information is calculated, and adjusts frequency change control signal to frequency converter output torque, specific to count to control wire spool rotating torque
Calculating step is:
A. diameter and remaining cable length locating for cable on cable drum are calculated, on the detected wire spool of encoder
The circle number of remaining cable is n, and cable linear diameter is d, and wire spool inside barrel diameter is D, then diameter locating for cable on wire spool
D1=D+ (2n-1) d, and remaining cable line length L=(nD+n2d) π；
B. torque calculation, tension needed for cable are power needed for overcoming the weight of the cable of pull-out, drawn out cable line be around
Remaining cable line length L on wire spool is subtracted around cable total length h on drum, then is h-L, cable unit weight is
M, then torque M needed for overcoming drawn out cable line weight=(h-L) (D+ (2n-1) d)；Because there is intrinsic static torque characteristics in equipment
M0, therefore actually required torque is (M+M0), the torque for being converted to frequency converter output signal is (M+M0)/N, and wherein N is reduction gearbox
Speed ratio.
Further, in ship powering phase, during carrying out above-mentioned direct torque, for avoid cable for a long time by
Compared with the influence of hightension, in the time t1 of setting when wire spool motionless (i.e. without take-up also without cable laying), reduce tension to overcoming
Tension needed for drawn out cable line weight；It is such as delayed after a period of time t2, wire spool is still acted without cable laying or take-up, is restored original
Tension；It is such as delayed after a period of time t2, generates cable laying, then recalculate tension and torque according to the above method；And so on.
The present invention sends control signal to PLC controller by the monitoring to cable real-time status, can be to marine vessel power
The running cable stretch of system cable lifting system carries out stable control, improves equipment operational reliability.
