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。 In order to improve the measurement accuracy of electronic balance based on double-end fixed tuning-fork load cell and the anti-interference performance in different scenarios, a data acquisition system is designed and the weighing data is transmitted to the host computer through the serial port for filtering analysis. According to the analysis results Select the corresponding filtering algorithm, and carry out the embedded system implementation, the filtering can achieve the purpose of improving measurement accuracy and resistance to a variety of environmental disturbances.
