HARDENED VOYAGE DATA RECORDER

摘要

PURPOSE: A hardened voyage data recorder is provided to protect data obtained by a voyage data recorder, thereby using the data during accidents or investigation. CONSTITUTION: A hardened voyage data recorder includes two sub-systems, which are a removable non-volatile memory module and a base containing electronics and firmware for communicating with data sensing systems and for accessing a memory(56). The memory is a stacked BGA(Ball Grid Array) memory protected in a boiler(58) which is designed to tolerate a low temperature fire environment for a relatively long term. The boiler and the memory module sub-systems are designed to withstand penetration forces associated with marine accidents. Cables from the memory are arranged not to damage the structural integrity of the boiler.
