| Summary: | International Telemetering Conference Proceedings / November 04-07, 1991 / Riviera Hotel and Convention Center, Las Vegas, Nevada === This paper introduces a multifunctional data acquisition system which has been developed. This system contains micro-computer and electronic memory, it adopts the method of hardware and software cooperation to control data acquisition, encoding, handling, storage and sending. It can acquire analog signal and digital signal, then output PCM data, and send data to transmitter after PSK modulation. It can real-time execute clock switching, changing of bit rate, writing data into memory or reading data from memory etc., according to the external command. The major handling function is data compression to reduce delayed data capacity. Basic characteristic of system, design consideration, data compression means and experiment result is represented in the paper, and emphasises on the handling means of independent subframe data inserted in digit form, and different design means of two electronic memory ( RAM and E PROM ) . |
