Abstract[English]
, fitting is performed to obtain a submarine cable profile; and the fitted submarine cable profile is compared with a preset allowable submarine cable profile, and accordingly, the angular velocity ω at which the carrier turntable rotates is adjusted, such that a plotted submarine cable profile matches the allowable submarine cable profile. The control method provided in the present invention can achieve the effect of controlling the tension of submarine cables, thereby preventing the submarine cables from being broken by the tension or damaged by compression; the matching accuracy between a submarine cable output speed of a carrier turntable and a submarine cable output speed of a cable-laying machine can also be improved; and when the submarine cable output speed is abnormal, warning information is sent, thereby improving the safety of submarine cable laying.[French]
, un ajustement est effectué pour obtenir un profil de câble sous-marin ; et le profil de câble sous-marin ajusté est comparé à un profil de câble sous-marin admissible prédéfini, et la vitesse angulaire ω à laquelle le plateau tournant de support tourne est ajustée en conséquence, de sorte qu'un profil de câble sous-marin tracé correspond au profil de câble sous-marin admissible. Le procédé de commande proposé dans la présente invention peut garantir l'effet de commande de la tension de câbles sous-marins, empêchant ainsi les câbles sous-marins d'être rompus par la tension ou endommagés par compression ; la précision de correspondance entre une vitesse de sortie de câble sous-marin d'un plateau tournant de support et une vitesse de sortie de câble sous-marin d'une machine de pose de câble peut également être améliorée ; et lorsque la vitesse de sortie de câble sous-marin est anormale, des informations d'avertissement sont envoyées, améliorant ainsi la sécurité de la pose de câble sous-marin.[Chinese]
，拟合出海缆线形，将拟合的海缆线形与预设的海缆允许线形进行比对，据此调整承载转盘转动的角速度ω，使绘制的海缆线形与海缆允许线形相匹配。本发明提供的控制方法能够达到控制海缆拉力的效果，避免海缆被拉力拉坏或被挤压致损，还能够提高承载转盘的海缆输出速度与布缆机的海缆输出速度匹配的精度，并在海缆输出速度出现异常时发出警示信息，提升海缆敷设的安全性。
