Abstract:

      This paper presents a design method for an automatic marine dumping monitoring system. It employs a high-speed single chip processor C8051F020 and a 943-series ultrasonic sensor made by Honywell Corporation. It elimininates the negative impact of ship sway and waves through a high-performance filtering algorithm. We therefore can obtain the exact ship waterline height. Such measurement data as GPS and vessel status are processed by a special encryption algorithm before sent to a database server through a DTU module. These data can serve as the legal basis for a dumping administration department.
