数据采集系统中温度数据的数字滤波算法分析

THE ANALYSIS OF DIGITAL FILTER FOR EMPERATURE DATA IN THE SYSTEM OF DATA COLLECTION

摘要: 数据采集系统已获得广泛应用,在工业生产和科学试验现场的电磁环境比较恶劣、干扰源较多时,一般要对采样数据进行数字滤波。结合数据采集系统中温度数据的特点,选择合理的数字滤波方式。针对具体的数据采集系统,通过试验确定温度数据的滤波参数。实践表明,利用复合数字滤波方法能够有效的提高温度数据的稳定性与准确性。

Abstract: The system of data collection obtain abroad application.We can use digital filter in this system,because there is a lot of electromagnetism which cause interference in the field of industry and science experiment.We can use the rational digital filter parameter by experiment and proper digital filter fashion to deal with the temperature data in the system of data collection.This method can improve the stability and the veracity of the temperature data.
