Abstract

We develop hardware and software for a long-term storage telemetry digital system. The system can be used for storing digitally in PCMCIA ATA flash memory card 33 analog channel data during several hours at low sample rate. The system is a portable unit powered by battery and contains 33 analog to digital converter, C/C++ programmable micro controller and PCMCIA memory. The proposed system could be reinstalled for up to 66 channels. The implemented unit is lightweight (about 1 pound). The unit records, converts, and stores the electric signals from sensors during the equipment operation. Some time after the flash memory will be downloaded at a commercial PC or a portable computer in a laboratory for diagnostic purposes. Data are stored in blocks of 512 bytes in PCMCIA memory (one sector). To optimize the memory available we used the compression technique based in wavelet functions.
