Research and Development of Signal Acquisition Unit Model

摘要

With core device 8051 Micro-controller and expanding IO-port through Intel 8255A to gather multi-channel signal, and the final results of data processing are sent out through serial ports. The paper, based on the characteristic of bit operation of 51-serie single-chip and by means of analysis method of mathematical statistics, develops a low-cost, simple-structure, reliable- function and highly efficient-algorithm signal acquisition unit model, which supplies parallel or serial communication interface and Can be further developed.
