Abstract

The invention discloses an automatic control method and device for a horizontal bird. The method comprises the following steps: reading real-time navigation data of a target horizontal bird to be adjusted; according to the navigation data, calculating to obtain a distance deviation and an integral term of the target horizontal bird; according to the distance deviation and the integral term, the to-be-adjusted angle of the target horizontal bird is calculated through the angle adjustment parameters, and the horizontal bird is automatically controlled to conduct wing plate angle adjustment according to the to-be-adjusted angle; wherein the angle adjustment parameter is obtained based on training of historical angle change data of the horizontal bird. By means of the method, the angle of the horizontal bird can be automatically adjusted, automatic control over the horizontal bird is achieved in time according to the real-time navigation data of the horizontal bird on the cable, the method is simple and efficient, the processing speed is high, the processing precision is high, manual intervention is little, and the quality of data collected based on the cable can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of offshore oil seismic exploration, in particular to an automatic control method and device for a horizontal bird. Background technique [0002] In the field of offshore oil seismic exploration, the towline geophysical exploration ship tows multiple cables. After the source is excited, the reflected wave from the seabed is collected through the cable, and the positioning data collected by the navigation and positioning system carried by the towline geophysical exploration vessel is combined to complete the acquisition of seismic data. . In the actual production process, the cable length can reach thousands of meters, and the cable spacing is between 50 and 200 meters. It is easily affected by factors such as ocean currents and towed fishing nets, resulting in inconsistent distribution of cable spacing and affecting the quality of seismic data acquisition. The horizontal bird is a cable horizont...
