A WIRELESS BALLAST WATER MONITORING AND REPORTING SYSTEM ANDMARINE VOYAGE DATA RECORDER SYSTEM

摘要

A ballast water monitoring and reporting system for seagoing vessels includes a sensor for monitoring a selected parameter of a ballast water system component and transmitting an electronic signal indicative of a condition of the parameter, a distal acoustic modem for receiving the signal from the sensor and for transmitting an acoustic signal equivalent to the electronic signal received, a shipboard metal structure extending substantially throughout the vessel and adapted to carry the acoustic signal, a proximal acoustic modem adapted to receive the acoustic signal from the metal structure and to transmit an electronic equivalent thereof, and a shipboard data acquisition computer adapted to receive the electronic signal from the proximal acoustic modem and to generate at least one of a display, a report relative to the selected parameter, and a recording of data relative to the selected parameter.
