Description
technical field [0001] The invention belongs to the technical field of automatic control of engineering ships, in particular to a device for measuring the angle of a bucket arm of a backhoe dredger by using an encoder. Background technique [0002] At present, the tracking accuracy of the bucket attitude plays an important role in the dredging efficiency of the backhoe dredger. Therefore, the measurement accuracy and reliability of the bucket angle as the angle signal acquisition device directly affects the tracking accuracy of the bucket attitude. Due to the complex working conditions of dredging ships, large vibrations and seawater corrosion, the measuring device is often a vulnerable device on board due to unreasonable design. [0003] With the increasing complexity of working conditions and the improvement of the dredging efficiency of dredgers, the accuracy requirements for bucket attitude tracking are becoming higher and higher. As for the angle measuring device, it c...
