Research on Distributed Status Monitoring System Based on Mixed-signal SOC

摘要

This paper uses C8051F020 and related signal conditioning circuits to build a front-end data acquisition system of some large-scale missile equipment status monitor system. By using the RS-485 interface, the data share between each front-end acquisition module and the main computer and the distributed status monitoring system are realized. The paper introduces the structure and data share mechanism of the monitoring system and discusses the solution methods to design the SOC-based data acquisition and signal conditioning circuits.
