挑战
当您每天 23 小时有多达 200 辆公共汽车在街上行驶时，必须不断监控您的车辆，以确保最高水平的准时性能和安全性。对于快速交通郊区交通管理局 (SMART) 而言，随着其自动车辆定位 (AVL) 系统的老化，这一挑战变得越来越困难。 AVL 使用无线电网络在每辆车和 SMART 的运营中心之间创建双向通信链路，调度员可以在其中监控车辆位置、调度性能和其他指标。 “我们的 AVL 已有 20 年历史，”SMART 的 IT 经理 Mel Evans 解释道。 “我们依赖于一个传统的模拟无线电网络，该网络使用三个租用的发射塔和一个正在退役的频率。虽然这个基础设施在 20 年前是令人满意的，但它并没有跟上 SMART 的步伐。我们想要更多的报告，我们想要可以与我们的公众乘客分享的实时信息。”一种选择是从模拟信号升级到数字信号并增加信号塔的数量。埃文斯指出，这将是成本高昂的。 “每台大约 100 万美元，升级策略对我们的机构来说太昂贵了，”他说。 “很明显，我们需要考虑一种涉及全新 AVL 解决方案的不同策略。”

为了提高监控车队、降低成本和摆脱模拟频率的能力，SMART 开始评估转向使用 IP 语音 (VoIP) 的蜂窝通信。该机构聘请了一名顾问来领导严格的评估/采购流程，这使 SMART 选择了 Clever Devices 的 AVL 解决方案，Clever Devices 是一家为有远见的交通机构提供通信和技术解决方案的领先供应商。 “Clever Devices 拥有丰富的经验，”Evans 说，“他们已经为其他交通机构实施了带有 VoIP 的 AVL。他们提出的蜂窝解决方案的核心是 Digi TransPort WR44 R 蜂窝路由器，我们对此印象深刻。” Digi TransPort WR44 R 是一款坚固耐用的企业级移动接入路由器。它专为需要为车载系统（例如安全视频、收费、CAD/AVL、VoIP 调度和乘客 Wi-Fi）提供可靠通信的交通机构和当局而设计。使用 IETF 互联网差分服务标准实现优先访问，确保 VoIP 呼叫和 CAD/AVL 功能在受限的蜂窝 LTE 链路上具有足够的带宽。收费和移动票务系统通常需要 PCI 合规性，WR44 R 通过其状态防火墙、IPSec VPN、网络分段和身份验证来提供。 Digi 远程管理器支持高效和有效的网络运营，提供关键功能，例如大规模更新、配置分析和车队监控以及性能指标报告和警报。

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.”
