Abstract

USB flash disk recorder is a new type paperless data recorder, which gathers the USB flash disk technology, micro-processing technology, and digital sensor technology together, taking the lead in applying USB flash disk technology. Massive data storage demand is met by adopting FatFS file system to manage storage media. The entire data will be stored in the form of file so that it is convenient for data storage and transmission. Moreover, the system concerned with the bad block management problems in NandFlash will be optimized and thus the reliability of the system will also improve. System test is performed by the accelerometer sensor. It is able to make long-term monitoring on the shock intensity and record the shock peak and waveform.
