基于STC12C5A60S2单片机的静态应变采集器设计

摘要

A static strain acquisition based on STC12LE5A60S2 and ARINC429 bus data output is introduced.The static strain has multi-channels sampling,hardware offset voltage,PGA and communication with the host computer and other functions.It is simple,stability,reliability and has good performance.It is used in much the aircraft tests.%介绍了一种基于STC12C5A60S2单片机和ARINC429总线输出的机载静态应变采集器.该采集器具有多通道循环选通采集,单通道硬件调零,程控增益放大和与PC机串行接口通信等功能.其结构简单,性能稳定,采集精度高,已应用于多个型号飞机的飞行试验中.
