Problems solved by technology

[0003] Most domestic and foreign shipyards use speed measurement methods that rely on manual command, manual counting, and manual data input and calculation. In the process of measurement experiments, experimental data errors are often caused by reasons such as personnel counting time inconsistencies, data omissions, and clerical errors. This led to the failure of the experiment, which seriously affected the accuracy of the experiment and wasted the trial voyage time. Secondly, before the data calculation, the data needs to be screened and filtered to filter the bad points in the measurement data to prevent the accuracy of the calculation results from being affected. At present, The common basis for data screening is the Chauvier criterion, but this criterion only screens each type of measurement data separately. When a certain data is found to be unqualified during the screening, it will not be delayed to other data collected at the same time. The problem of missing unqualified data

Description

technical field [0001] The invention belongs to the field of ship design and construction, and in particular relates to a correction method of a ship trial performance index, a correction system storage medium and an electronic terminal. Background technique [0002] Currently, the vigorous development of international trade and economic globalization has brought prosperity to the shipbuilding industry. In the process of ship design and construction, ship speed, power, and rotational speed are important indicators for evaluating ship performance. How to measure the ship's speed more accurately and conveniently is a problem that designers and builders have been concerned about. [0003] Most domestic and foreign shipyards use speed measurement methods that rely on manual command, manual counting, and manual data input and calculation. In the process of measurement experiments, experimental data errors are often caused by reasons such as personnel counting time inconsistencie...
