摘要
单片机数据采集系统在单片机自动测量、自动控制等领域具有广泛的应用,在数据采集环境,不可避免地将要产生各种各样的干扰和破坏,造成信号突变或中断,进而影响采集数据的正确性和精确性,造成控制错误等严重后果。因此研究单片机采集系统的抗干扰技术,是单片机应用技术的重要一环。文中采用数字滤波实现单片机的抗干扰技术,结合使用多种滤波算法,达到既消除高频干扰,又避免脉冲干扰的目的。
The data acquisition systems on MCU are used widely in the fields of automatic measurement, automatic control and others. On the special environment, a variety of interference and damage produces inevitably,then resuks in mutations or interruption of the signal, and then affects the accuracy of the data, sometimes results in the serious consequences of the control error. Therefore, the research on the microcontroUer collection system anti-jamming technology is an important part of the MCU application. This paper used the digital filter to achieve MCU＇ s anti-jamming technology, combined with a variety of filtering algorithms, can eliminate the high frefltlencv intorforonro ,rid fh ]~o ;~.4＂
