解决方案
Litum 设计了一个使用 UWB RFID 技术开发的 RTLS 系统，该系统利用在网状网络结构上运行的 RTLS 标签（发射器）和 RTLS 锚点（接收器）。
Litum 制造了该系统，包括 RTLS UWB 锚 [阅读器]、标签、固件和软件，此外还提供安装和持续支持。在隧道本身中，安装了 48 个锚（阅读器）来捕获来自徽章的传输。每个锚点的读取距离为地上 150 米（492 英尺），在隧道中的读取距离约为 100 米（328 英尺）。
工人的标签与他们的身份证相匹配，并通过戴上他们的头盔来佩戴。系统通过网状网络结构将每个标签 ID 及其位置无线转发到网关锚点。然后网关将数据转发到 Litum 基于云的软件，以更新个人的位置和运动。标签的精确位置由 Litum 的定位引擎软件使用专有算法计算得出。该位置的计算精度约为 50 厘米（19.7 英寸）。因此，当每个工人在工地周围移动并穿过隧道时，他或她的位置会在仪表板地图上显示为一个点。这样，管理层可以实时查看所有人员的位置，并收集和存储历史数据。
如果发生事件，例如未经授权的个人进入禁区，则会直接向现场经理或主管发出警报，然后他们可以快速解决问题。对于现场可能发生的紧急情况，系统管理员可以单独或集体向员工胸牌发出警报，以进行预警。此外，RTLS UWB 节点安装在整个隧道中，每 100 米（656 英尺）。这些节点带有一个按钮，可以按下该按钮来激活警报系统，这使工作人员能够在需要时激活警报系统。通信的双向特性使紧急警报管理更容易。当警报激活时，通过显示每个工人位置的软件，疏散更加安全和安全。

Airport SCADA Systems Improve Service Levels
Modern airports are one of the busiest environments on Earth and rely on process automation equipment to ensure service operators achieve their KPIs. Increasingly airport SCADA systems are being used to control all aspects of the operation and associated facilities. This is because unplanned system downtime can cost dearly, both in terms of reduced revenues and the associated loss of customer satisfaction due to inevitable travel inconvenience and disruption.

Vehicle Fleet Analytics
Organizations frequently implement a maintenance strategy for their fleets of vehicles using a combination of time and usage based maintenance schedules. While effective as a whole, time and usage based schedules do not take into account driving patterns, environmental factors, and sensors currently deployed within the vehicle measuring crank voltage, ignition voltage, and acceleration, all of which have a significant influence on the overall health of the vehicle.In a typical fleet, a large percentage of road calls are related to electrical failure, with battery failure being a common cause. Battery failures result in unmet service agreement levels and costly re-adjustment of scheduled to provide replacement vehicles. To reduce the impact of unplanned maintenance, the transportation logistics company was interested in a trial of C3 Vehicle Fleet Analytics.

3M Gains Real-Time Insight with Cloud Solution
The company has a long track record of innovative technology solutions. For example, 3M helps its customers optimize parking operations by automating fee collection and other processes. To improve support for this rapidly expanding segment, 3M needed to automate its own data collection and reporting. The company had recently purchased the assets of parking, tolling, and automatic license plate reader businesses, and required better insight into these acquisitions. Chad Reed, Global Business Manager for 3M Parking Systems, says, “With thousands of installations across the world, we couldn’t keep track of our software and hardware deployments, which made it difficult to understand our market penetration.” 3M wanted a tracking application that sales staff could use to get real-time information about the type and location of 3M products in parking lots and garages. So that it could be used on-site with potential customers, the solution would have to provide access to data anytime, anywhere, and from an array of mobile devices. Jason Fox, Mobile Application Architect at 3M, upped the ante by volunteering to deliver the new app in one weekend. For Fox and his team, these requirements meant turning to the cloud instead of an on-premises datacenter. “My first thought was to go directly to the cloud because we needed to provide access not only to our salespeople, but to resellers who didn’t have access to our internal network,” says Fox. “The cloud just seemed like a logical choice.”
