摘要
The detection of stray bodies uses the signals supplied by mechanical pulse sensors, such as accelerometers supported by separate structures of the vessel. The detection installation comprises means for detecting the coincidences between pulse signals supplied by the different sensors and having a peak factor higher than a given level, fixed by an external reference. An alarm is triggered off when the coincidence rate provided by a counter associated with a threshold circuit exceeds a given value.
