2019新冠肺炎病毒(COVID-19)如何影响物联网

由  Wiren Perera 发布  - 10-06-2020 

不可否认,我们正活在非凡的时代。目前的流行病继续迫使分析家们重新审视关于未来几个月各领域将如何增长或下降的预测。2020年以后,期望复苏将完成,甚至会超过之前预测的某些领域的增长。一个可能会出现显著上升的领域是物联网(IoT),更具体地说,是远程监控和自动化。

COVID-19对IoT方案需求的积极、短期影响的证据已经存在。互联医疗设备的销售和使用增加了,一家制造商报告说,其智能体温计现在在美国使用了近200万个。这是否预示着一种长期的趋势,甚至是永久性的行为变化还有待观察,但它是一个更广泛趋势的表征。

远程会议和虚拟咨询

其他例子包括利用在线服务进行远程会议,包括与卫生专业人员进行磋商。视频咨询的实施相对简单,但也有联接诊断站的例子,使病人在医疗专业人员的监督下使用联接到互联网的医疗设备,以便进行更彻底的远程检查。如果人们接受了这一种可行的替代方式,而不是亲自去看医生,那么完全可以期待使用该方式会增加。

人员监控

人员监控是另一个几乎是全新的应用领域,正在由智能技术来实现。这可能包括使用摄像头来检测公共场所形成的未经授权的群体,但它也被用于跟踪人们及其相互之间的接近程度。这提供了一种相对不显眼的方式,在我们接近回归更正常的生活时,通过跟踪和追踪来确保社交距离。

自主移动机器人

以一种不太直接的方式,我们也可以预期像COVID-19这样的大流行病的后果会加速当前趋势的步伐,比如转向自动车辆。送货的最后一段通常涉及将包裹从送货车辆上送到建筑物。它几乎总是由送货员步行和人手进行。在不久的将来,我们可以预期,最后一段路程将由自主移动机器人来完成,在这个过程中消除了人手,并提高了包裹交付等日常活动的社交距离程度。一些技术是这些场景的基础。它们并不是新的技术,几年来它们一直在使IoT及其许多现有的应用成为可能,但它们也将是实现新常态的关键。这些技术可以大致归纳为感知、理解和通信三个标题。

COVID-19期间和之后的赋能技术

从感知的角度来看,许多新的应用将使用图像传感器作为它们的眼睛。与图像传感器相辅相成的是激光雷达、超声波和雷达,它们有助于深度感知、避免碰撞和物体识别。图像传感器传统上是用来捕捉人使用的信息,但机器使用图像传感器数据而不需要人参与的情况越来越普遍。这将支持COVID-19后的一些应用,例如通过面部识别技术实现免触摸的建筑物访问,甚至是自动服务,如洗手或分配消毒凝胶。

智能设备对环境的理解能力将在很大程度上依赖于它们能够提供的数据质量。像AR0237IR这样的传感器能够同时获得可见光和红外图像,同时即使在低光照条件下也能提供良好的灵敏度。这有几个积极的好处,它提供了更快的可操作数据的时间,并减少了对云服务的高带宽联接的依赖。

借用一句话,在边缘处理数据无疑不仅仅是一种温和的趋势,它将成为 "新常态"。安森美半导体如何赋能这一点的一个例子是集成蓝牙低功耗联接的RSL10系统级单芯片。这款微型器件能提供一个智能传感器节点所需的绝大部分功能,包括与更广泛的IoT通信的传输机制。

RSL10这样的方案非常重要,因为带宽是IoT所消耗的贪得无厌的宝贵商品。业界正在不断开发新的方法,以更好地使用带宽并扩大其可用性。RSL10是其中一个例子,但另一个例子是Wi-Fi的持续发展。最新一代的Wi-Fi 6和Wi-Fi 6E就完美地诠释了这一点。安森美半导体的Quantenna联接方案分部走在Wi-Fi技术的前沿,其QCS-AX2芯片组提供双频和三频联接,使Wi-Fi 5向Wi-Fi 6/6E无缝迁移。Wi-Fi 6/6E所提供的更高带宽和功能将变得更加重要,因为我们实现另一层联接的设备,以帮助我们在家庭、办公室和公共场所保持安全。

我们可以确信,世界将从COVID-19中恢复过来,并为接下来不可避免的事情做好更好的准备。
