The implementation of traditional sensors is a drawback when investigating mass transfer phenomena within microstructured devices, since they disturb the flow and reactor characteristics. An Arduino based slider setup is developed, which is equipped with a computer-vision system to track gas–liquid slug flow. This setup is combined with an optical analytical method allowing to compare experimental results against CFD simulations and investigate the entire lifetime of a single liquid slug with high spatial and temporal resolution. Volumetric mass transfer coefficients are measured and compared with data from literature and the mass transfer contribution of the liquid film is discussed. 相似文献

为了实现对假手的智能控制,文中提出一种基于语音控制的设计方案。语音识别系统接收发音人的语音命令,并将语音命令转换成主控系统能识别的数字信号。主控系统接收数字信号,同时根据命令向指关节发送数据驱动指关节伺服电机正向或反向转动。指关节转动的角度被指关节电位器转换成相应的电信号。主控系统将角度电信号转换成数字信号,并将此数字信号和命令初始数据比较,从而发出修正命令数据,驱动指关节伺服电机走到指定的位置。在抓握不同物品时,本系统中在每个指尖安装有高灵敏度的压力传感器以检测指尖的受力,确保物品既被抓牢又不被压坏,从而实现对假手的智能控制。 相似文献

This paper presents a novel distributed data analytic architecture, and corresponding algorithms that apply to infrastructure anomaly detection. The proposed method mainly focuses on smart water networks, demonstrating that the highest possible sensor rate analytic performs at on-edge nodes without requiring the whole date to send back to the server. This approach saves communication costs and lengthens the lifetime of the battery-powered nodes. A complex set of tasks is developed on a single-core Intel Curie processor, Arduino101 and the raw sensor data is compressed using a customized Lempel–Ziv compression algorithm tailored to resource-constrained embedded systems. The compression rate figures are then analyzed but only the compressed data which is associated with the anomalous condition is sent back to the server by means of a LoRa platform. The developed system is evaluated experimentally and the results verify the high resource utilization. 相似文献

监控是安防系统中应用最多的系统之一,视频监控现在是主流.现有的视频监控方式采用固定式摄像装置对图像进行捕捉并上传,但是这种固定式摄像装置的图像捕捉区域小,若是针对大范围或是复杂空间时,就需要通过广设摄像装置去实现针对该空间的监控,这样不论是在监控建设方面、还是成本方面,都是件不合理、不经济的工程.本设计采用Arduino为中心器件来设计控制主板,系统使用灵活、操作简单、监控范围广,可有效弥补传统监控方式中的不足. 相似文献
