The invention provides a multi-point
mooring and positioning constant-tension self-
adaptive control system and method for a ship. The multi-point
mooring and positioning constant-tension self-
adaptive control system comprises m
mooring winches, a detection
system and a monitoring
station. Each mooring
winch is provided with the following detection equipment including an
encoder, a tension sensor, a mooring cable angle sensor, a
brake position proximity switch, a
clutch position proximity switch and a
ratchet wheel and pawl position proximity switch, wherein the
encoder is used for detecting the length value and the speed value of a mooring cable; the tension sensor is used for detecting the real-time tension value of the mooring cable; the mooring cable angle sensor is used for detecting the
vertical angle and the
horizontal angle of an anchor cable; the
brake position proximity switch is used for detecting the on-off state of a
brake; the
clutch position proximity switch is used for detecting the on-off state of a
clutch; and the
ratchet wheel and pawl position proximity switch is used for detecting the on-off state of a
ratchet wheel and pawl stopping device. The monitoring
station is connected with all
servo drivers and all the pieces of detection equipment. The multi-point mooring and positioning constant-tension self-
adaptive control system and method for the ship have the advantages of being simple in structure, economical, reliable, accurate in positioning, low in positioning cost and low in
energy consumption.
