Abstract
Abstract The disclosure relates to a microprocessor based telemetry apparatus and method utilizing a commercially available IBM PC-AT or compatible CPU. Three hardware cards fit in existing slots within the computer chassis. Software is provided to accomplish, in combination with the cards, what has essentially required a main frame computer heretofore. The microcomputer is equipped with novel hardware and software to provide PCM bit synchronizer/decoder, decommutator, time code reader and digital-to-analog converter functions. Data is stored in real time using interleaved buffers, novel software and a hard disk. Data can be archived on digital tape. Data logging can be carried out at sustained rates approaching 2 million bits per second, up to six times faster than with MS-DOS yet files are accessible with MS-DOS. Real-time data scaling and display of up to 128 separate parameters are accomplished.
