关于客户
科罗拉多大学博尔德分校的天线研究小组 (ARG) 是一个领先的研究中心,位于电气、计算机和能源工程系。 ARG致力于天线理论和设计的研究,重点是电子小型天线、同步发射和接收技术以及用于电子攻击、电子支持和通信的宽带微波和毫米波天线的应用。在 Dejan Filipovic 博士的指导下,ARG 团队设计并交付了许多工作频率低至 2 MHz 和高至 220 THz 的宽带和窄带天线系统。科罗拉多大学博尔德分校的 ARG 致力于天线研究和设计已有 15 年的历史。研究组现有博士后研究员8人,博士生14人,本科生研究生2人,研究管理人员2人。迄今为止,该小组已发表超过 225 篇经过同行评审的期刊出版物、会议论文、短期课程和教程。
挑战
科罗拉多大学博尔德分校的天线研究小组 (ARG) 的任务是评估车辆底部,作为安装高频 VHF 天线系统的更传统天线放置位置的替代方案。面临的挑战是开发一种程序来评估军用车辆底部放置 HF-VHF 天线的可行性。许多军用和商用车辆平台的各种应用通常需要薄型隐藏式天线。然而,这些高天线增加了车辆的垂直间隙并构成易于识别的视觉特征,这是不期望的。车辆底部可以被认为是一个可行的隐藏替代场所,因为它提供了足够的空间来避免天线极端小型化。面临的挑战是评估和比较不同车辆位置的天线的传播损耗。
解决方案
解决方案是应用 FEKO 电磁场仿真方法来评估底部放置天线的性能。数值研究是用车辆模型进行的。假设全金属结构是完美的电导体,而天线源近似为放置在距离车辆表面 0.05 m 处的顶部和底部位置的赫兹电偶极子。 FEKO 通过代码中实现的索末菲积分来计算接地损耗。考虑了三种类型的地面,包括干沙、沥青和湿土。 ARG 项目团队严重依赖 FEKO 结果来验证其传播损耗计算的分析程序,然后使用开发的 FEKO 模型准确确定各种天线/平台系统的影响范围。从全向性、效率和传播损耗方面评估了不同位置的车载天线的性能。

Case Study
Integral Plant Maintenance
Mercedes-Benz and his partner GAZ chose Siemens to be its maintenance partner at a new engine plant in Yaroslavl, Russia. The new plant offers a capacity to manufacture diesel engines for the Russian market, for locally produced Sprinter Classic. In addition to engines for the local market, the Yaroslavl plant will also produce spare parts. Mercedes-Benz Russia and his partner needed a service partner in order to ensure the operation of these lines in a maintenance partnership arrangement. The challenges included coordinating the entire maintenance management operation, in particular inspections, corrective and predictive maintenance activities, and the optimizing spare parts management. Siemens developed a customized maintenance solution that includes all electronic and mechanical maintenance activities (Integral Plant Maintenance).

Hydro One Leads the Way In Smart Meter Development
In 2010, Ontario’s energy board mandated that time-of-use (TOU) pricing for consumers be available for all consumers on a regulated price plan. To meet this requirement, Hydro One needed to quickly deploy a smart meter and intelligent communications network solution to meet the provincial government’s requirement at a low cost. The network needed to cover Hydro One’s expansive service territory, which has a land mass twice the size of Texas, and its customers live in a mix of urban, rural, and remote areas, some places only accessible by air, rail, boat or snowmobile. Most importantly, the network needed to enable future enterprise-wide business efficiencies, modernization of distribution infrastructure and enhanced customer service. To meet these needs, Hydro One conceptualized an end-to-end solution leveraging open standards and Internet Protocols (IP) at all communication levels. The utility drew upon industry leaders like Trilliant to realize this vision.

Monitoring of Pressure Pumps in Automotive Industry
A large German/American producer of auto parts uses high-pressure pumps to deburr machined parts as a part of its production and quality check process. They decided to monitor these pumps to make sure they work properly and that they can see any indications leading to a potential failure before it affects their process.
