METHOD TO CONTROL SHIP STRENGTH AND VIBRATION AND DEVICE TO THIS END Russian patent published in 2009 - IPC G01M7/02 

FIELD: measurements.

SUBSTANCE: proposed method and device relate to control instrumentation and can be used for continuous non-destructive testing, estimation and forecasting of technical state of ship hull during entire service life. Proposed method comprises the steps that follow. Signals from measurement units mounted on hull structures are recorded and compared with pre-recorded magnitudes. Given unpredictable, especially, abnormal and extreme conditions, control methods incorporate data processing neuron network algorithms and decision-making methods built around onboard digital computer representing a multi-processor complex, neurocomputer and fuzzy logic processor. Proposed device comprises control board, measurement units arranged at the ship hull points to be tested, transducers, controller, modem and transmission line. Note that measurement units are arranged at points most susceptible to outer dynamic loads and vibration. There structural components are connected to appropriate transducers that are, in their turn, connected to controller input. The controller is connected to modem, in its turn connected to control board that comprises operator monitor. Aforesaid monitor is connected, via appropriate interfaces, with onboard computer, neurocomputer and fuzzy logic processor. The three later devices allow operation of intellectual system and neurocontroller that exercise control over data processing logical units under extreme and abnormal conditions related with intolerable deviation of strength and vibration parameters and faults of measurement units.

EFFECT: simple, reliable and efficient method of control and gaining accurate and valid data.
