Winch rotation detection device and method

Abstract

The invention discloses a winch rotation detection device and method and belongs the field of deck machinery. The detection device comprises sensing blocks, three proximity sensors and a processing module, wherein the sensing blocks are arranged at equal intervals along the circumference direction of a winch with a winch rotating shaft being as the center; the three proximity sensors are arranged opposite to the plane, where the sensing blocks locate; and the processing module receives pulse signals output by the three proximity sensors. Through reasonable setting of size and position relation of parts of the detection device, the three paths of pulse signals output by the three proximity sensors are allowed to have appropriate phase difference; then, the processing module carries out analysis on the three paths of pulse signals to obtain winch rotation direction and angle; and when the detection device works, the proximity sensors do not make direct contact with the winch, thereby preventing vibration obtained when the winch works from influencing the detection device.

Description

technical field [0001] The invention relates to the field of deck machinery, in particular to a winch rotation detection device and method. Background technique [0002] The winch is used as an anchor handling device. When working, the winch is driven by power to rotate to retract and release the anchor chain, thereby completing the anchor handling action. In order to realize automatic control, it is usually necessary to detect the direction and angle of rotation. Rotary encoders are usually used for rotation detection, and the input shaft of the rotary encoder is coaxially connected with the rotating shaft of the winch under test. The pulse signal sent out to obtain the rotation direction and rotation angle of the winch. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] The winch often vibrates violently in actual work, and the violent axial and radial jumps caused by th...
