Study on Communication Automation with Embedded Real Time Signal Acquisition and Process System Based on PC104

摘要

To meet the demand of communication automation for outfield equipment test module, special embedded system was proposed by combing host computer control board and signal acquisition board, taking advantage of high data transmission efficiency on PC104 bus. Multichannel switch, signal recuperation circuit and Analog to Digital Converter (ADC) were controlled by FPGA logic on signal acquisition board. Signal data acquired were transmitted to host computer control board to display for user in real time. Application shows that the system was easy to operate. It performs well on real time ability and stability.
