Abstract

The invention discloses a ship operation man-hour measuring and calculating method, system and device and a medium, and belongs to the technical field of ship measuring and calculating. According to the method, the problem of low precision of existing working hour measurement and calculation is solved, the operation time data and the original signal are collected and processed respectively, the three-axis acceleration information is obtained through the original signal, the standard deviation is calculated to obtain the three-axis acceleration standard deviation signal, the vibration frequency information is obtained and extracted, and the accuracy of working hour measurement and calculation is improved. A neural network is used to establish a model, and the model is trained through vibration frequency information and operation time data, so that the vibration frequency information can be predicted through the model, and the operation time of multiple engines or generators of a ship can be measured and calculated by comparing the time interval between the actual vibration frequency and the predicted vibration frequency. The problems of false reporting and missing reporting caused by manual reporting are avoided, and accurate measurement and calculation of ship operation working hours are ensured.
