摘　　要：为提高基于双端固定音叉式称重传感器的电子天平测量精度以及不同场景下抗干扰的性能,设计了一个数据采集系统并通过串口将称重数据传送至上位计算机进行滤波分析处理,根据分析结果选择相应的滤波算法,并进行了嵌入式系统实现,该滤波能达到提高测量精度与抗多种环境干扰的目的。For the requirement of measuring accuracy and anti-inference in different scenes of electronic balance based on Double-Ended Tuning Fork（DETF）, a data collecting system is designed and the weighing data are transmitted to host computer by serial ports. By data analyzing, a corresponding filtering algorithm is chosen and realized in embedded sys- tems. The results show that the filtering algorithm could improve the measuring accuracy and resistance to interference in various environments.
