The large-scale equipment in ocean engineering basically needs to be subjected to a pool model test before launching, and motion data, structural stress conditions and the like of a reliable ship body are obtained through the test, so that a reliable basis is provided for the design of ocean equipment.
When the model wave test is carried out in the ship model test pool, the model object in the water generally needs to be shot synchronously, and the state of the model object in the wave during the test can be observed again at the later stage, so that the test scheme can be adjusted or the model object can be provided for the first party. The shooting and recording requirements of the test working conditions are complete, shooting is started before the waves generated by the wave generator reach the model, the shooting cannot be stopped immediately after the wave generator stops shooting, and the shooting is stopped after the waves naturally attenuate to a certain degree. Therefore, a tester needs to repeatedly operate the camera, start shooting when the wave generation of one test working condition starts, and stop shooting when the wave generation is finished. Sometimes, the tester forgets to start the camera in time, so that the test working condition is not shot, sometimes, the tester forgets to stop the camera, so that a plurality of garbage video files are recorded, and in addition, the operation of camera shooting and recording belongs to the repetitive labor with lower technical content, so that the resource of the tester is wasted.
Whether wave making is started or not is judged by the detection instrument, then the camera system is synchronously started, the scheme is feasible, but the method is more complicated and is easy to misjudge. If the wave making machine control system can have the function of synchronous shooting, the scheme is more direct and efficient.
