Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0022] like figure 1 As shown, the control system of the present invention includes a hot standby redundant controller 1, a frequency converter group 4, an AC variable frequency motor 8, a transmission planetary gear train, an armored umbilical cable 11, a reel 12 and a signal detection sensor, and the signal detection The sensor collects the rotational speed of the reel 12 and the heave acceleration of the mother ship. The signal detection sensor includes an angle encoder 13 and an acceleration sensor 14. The angle encoder 13 is installed on the main shaft of the reel 12, and the acceleration sensor 14 is installed on the mother ship. 13 and the signal output end of the acceleration sensor 14 are connected with the hot standby redundant controller 1, and the collected signal is sent to the hot standby redundant controller 1, and the hot standby redunda...
