With the development of data monitoring system for industrial equipment, the convenience of data monitoring is paid more and more attention. Traditional data monitoring mostly uses specialized software or visual interface on the device to achieve the purpose of monitoring data, the workflow will be more complex. Even if there is a unified device to receive the data, it is not realistic to monitor all the time. In addition, for the load problem of the micro device, mounting the OPC UA client by itself is heavy. Therefore, in order to improve the visibility of field device data, reduce the load of micro devices and simplify the complex workflow, this paper studies the cross-platform device monitoring system based on OPC UA. The local OPC UA server is used to collect data from industrial devices, and the collected data is processed and transferred to the cloud storage system. The stateless RESTful HTTP request style simplifies the complexity of implementing data transfer between a generic client (browser or other HTTP client) and a Web server, and truly enables users to monitor data anytime and anywhere without consuming too many resources.
随着工业设备数据监控系统的发展,数据监控的便利性越来越受到人们的重视。传统的数据监控大多采用专门的软件或设备上的可视化界面来达到监控数据的目的,工作流程会比较复杂。即使有一个统一的设备来接收数据,也不可能一直监控。另外,对于微设备的负载问题,单独挂载OPC UA客户端是很繁重的。因此,为了提高现场设备数据的可视性,减轻微型设备的负载,简化复杂的工作流程,本文研究了基于OPC UA的跨平台设备监控系统。本地OPC UA服务器用于采集工业设备的数据,并将采集到的数据处理后传输到云存储系统。无状态RESTful HTTP请求样式简化了在通用客户端(浏览器或其他HTTP客户端)和Web服务器之间实现数据传输的复杂性,使用户能够在不消耗太多资源的情况下随时随地监控数据。

In recent years, real-time 3D reconstruction has gained popularity among many researchers due to its increasing applications. 3D reconstruction methods based on depth estimation have a large number of invalid areas for reconstruction in autonomous driving. To further improve the real-time performance of 3D reconstruction, we propose a novel approach to reduce the consumption of computational resources by extracting significant regions of depth maps. First, binary masks that extract significant regions are generated by a 2D object detection model. Then, we design the TRDE module to extract target regions in generated depth maps. Finally, qualitative and quantitative results on KITTI dataset demonstrate that our approach can perform depth maps optimization and reduce computational resources consumed during the 3D reconstruction. As a result, our method achieves faster 3D reconstruction by fusing 2D object detection and self-supervised monocular depth estimation.
近年来,实时三维重建由于其越来越多的应用而受到许多研究人员的欢迎。基于深度估计的三维重建方法在自动驾驶中存在大量重构无效区域。为了进一步提高三维重建的实时性,我们提出了一种新的方法,通过提取深度图的重要区域来减少计算资源的消耗。首先,通过二维目标检测模型生成提取重要区域的二值掩码。然后,设计TRDE模块,在生成的深度图中提取目标区域。最后,在KITTI数据集上的定性和定量结果表明,我们的方法可以进行深度图优化,减少三维重建过程中的计算资源消耗。因此,我们的方法通过融合二维目标检测和自监督单目深度估计实现了更快的三维重建。

When a disaster strikes, we evacuate to a shelter. We abandon evacuation or wander aimlessly toward an unknown shelter if we do not remember shelter locations; in the worst-case scenario, we may lose lives before or during evacuation. Residents should remember not only shelter locations in their local community but also shelter capacities and features. In many cases, every resident evacuates to the nearest shelter. If many residents rush into the nearest but small-capacity shelter, some will be unable to enter and will have to go to another shelter. This time-consuming situation must be resolved to help residents evacuate successfully. Furthermore, residents with special needs may end up in an inappropriate shelter if they are unfamiliar with the features of the shelter. We believe that by visiting and observing shelters in advance, residents will be able to recall not only shelter locations and capacities but also shelter features. However, it is difficult to maintain motivation to visit shelters, especially when the shelters are located in remote areas. As a result, we created a prototyped location-based game (a mobile application) that used a geofencing framework similar to Pokémon GO and encouraged players (residents) to visit shelters through a game element. In this game, players visit a shelter to earn a point equal to the shelter's capacity and visit an informative spot about disaster management to collect a digital character by paying a required point from their earned points. The character collection can encourage players to visit numerous shelters, which can lead to remembering numerous shelter locations, capacities and features. We conducted a preliminary comparative experiment, in which the participants were given the task to remember shelter locations and capacities by playing a game or staring at a hazard map. The results of the experiment indicated that our game prototype was effective in helping the participants remember shelter locations and capacities.
当灾难来袭时,我们疏散到避难所。如果我们不记得避难所的位置,我们就会放弃撤离,或者漫无目的地向一个未知的避难所走去;在最坏的情况下,我们可能在撤离前或撤离过程中丧生。居民不仅要记住当地社区的庇护所位置,还要记住庇护所的容量和特征。在许多情况下,每个居民都疏散到最近的避难所。如果许多居民涌入最近但容量较小的避难所,一些人将无法进入,不得不前往另一个避难所。这一耗时的情况必须得到解决,以帮助居民顺利撤离。此外,有特殊需要的居民如果不熟悉收容所的特点,可能会被安置在不合适的收容所。我们相信,通过提前参观和观察避难所,居民不仅可以回忆起避难所的位置和容量,还可以回忆起避难所的特征。然而,很难保持访问避难所的动力,特别是当避难所位于偏远地区时。因此,我们创造了一款基于地理位置的游戏原型(一款手机应用),它使用了类似于《pokemon GO》的地理围栏框架,并鼓励玩家(居民)通过游戏元素访问庇护所。在这款游戏中,玩家访问一个避难所可以获得与避难所容量相等的点数,访问一个关于灾难管理的信息点,通过从他们获得的点数中支付所需点数来收集一个数字角色。角色收集可以鼓励玩家访问许多避难所,这可以让他们记住许多避难所的位置、容量和功能。我们进行了一个初步的比较实验,在这个实验中,参与者被要求通过玩游戏或盯着危险地图来记住避难所的位置和容量。实验结果表明,我们的游戏原型能够有效地帮助参与者记住庇护所的位置和容量。

In this game, players visit a shelter to earn a point equal to the shelter's capacity and visit an informative spot about disaster management to collect a digital character by paying a required point from their earned points. The character collection can encourage players to visit numerous shelters, which can lead to remembering numerous shelter locations, capacities and features. We conducted a preliminary comparative experiment, in which the participants were given the task to remember shelter locations and capacities by playing a game or staring at a hazard map. The results of the experiment indicated that our game prototype was effective in helping the participants remember shelter locations and capacities.","PeriodicalId":290836,"journal":{"name":"2022 11th International Conference of Information and Communication Technology (ICTech))","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122909443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We propose an improved YOLOv4 small target detection method for small target foreign object (FOD) recognition that requires as few detection accuracy, speed, and model volume parameters as possible so that it can be easily ported to other mobile devices such as video surveillance or UAVs in the future. Firstly, the backbone feature extraction network of YOLOv4 is replaced by the MobileNetV2 model, which aims to reduce the number of model parameters. Secondly, the three enhanced feature extraction layers of the original YOLOv4 are increased to four, and a new shallow-scale enhanced feature extraction layer is added, which enhances the characterization capability of the model without increasing the model complexity, making the improved YOLOv3 network structure better for small target detection.
我们提出了一种改进的YOLOv4小目标检测方法,用于小目标异物(FOD)识别,该方法对检测精度、速度和模型体积参数的要求尽可能低,以便将来可以很容易地移植到视频监控或无人机等其他移动设备上。首先,将YOLOv4的主干特征提取网络替换为MobileNetV2模型,以减少模型参数的数量;其次,将原YOLOv4的3个增强特征提取层增加到4个,并增加了一个新的浅尺度增强特征提取层,在不增加模型复杂度的情况下增强了模型的表征能力,使改进后的YOLOv3网络结构更适合小目标检测。
