关于客户
韩国气象厅 (KMA) 是韩国环境部的一个组织,其使命是保护公民的生命和财产免受自然灾害的影响,并通过支持经济活动的方式改善公共福利。 KMA 观测并分析地面、海洋和大气中的气象现象,同时提供天气预报和警报,并提供气候统计数据和工业气象数据。 KMA 与国内外组织交换气象数据和信息,开展研究和技术开发活动,并促进国际合作。 KMA 拥有 1313 名公务员,共运营 97 个气象站,其中包括 11 个雷达、5 个高空观测站和 477 个自动气象站。
挑战
韩国气象局 (KMA) 面临着降低能耗的挑战,同时保持其新型超级计算机 4 单元(Cray® XC40™ 系统)的性能。该系统配备了超过十万个计算核心,每秒运行千万亿次计算作业,消耗大量能源并产生高热量。为了平衡运行,保持国家气象超级计算机中心 (NCMS) 处于凉爽和恒温状态至关重要。然而,超级计算机4号单元所需的能源消耗增加,给空调(A/C)系统的运行带来了巨大的负担。 KMA 需要确定处理额外能源消耗和冷却需求的要求。
解决方案
为了应对这一挑战,KMA 与 Cray 和 Altair 合作,模拟其 NCMS 中空调系统的预期工作条件。 KMA 选择 Altair 的 PBS Professional 作为其工作负载管理器,并选择 Altair 的 AcuSolve(计算流体动力学 (CFD) 求解器)用于 A/C 系统分析。该方法首先使用 AcuSolve 对 KMA 计算室地板的双重结构进行建模。该分析重点关注 KMA 计算室的气流状况和热点现象,以及操作可降低室温的恒温恒湿器可能产生的影响。 KMA 和 Altair 韩国公司设定了几种关闭一定数量恒温恒湿器的方案,以减少每个计算室的能源消耗。根据结果,他们确定了每个机房应运行的最少恒温恒湿器数量,并发现即使运行最少数量的恒温恒湿器,空调系统也能正常工作,不会对运行产生任何严重的不利影响。超级计算机。

IoT System for Tunnel Construction
The Zenitaka Corporation ('Zenitaka') has two major business areas: its architectural business focuses on structures such as government buildings, office buildings, and commercial facilities, while its civil engineering business is targeted at structures such as tunnels, bridges and dams. Within these areas, there presented two issues that have always persisted in regard to the construction of mountain tunnels. These issues are 'improving safety" and "reducing energy consumption". Mountain tunnels construction requires a massive amount of electricity. This is because there are many kinds of electrical equipment being used day and night, including construction machinery, construction lighting, and ventilating fan. Despite this, the amount of power consumption is generally not tightly managed. In many cases, the exact amount of power consumption is only ascertained when the bill from the power company becomes available. Sometimes, corporations install demand-monitoring equipment to help curb the maximum power demanded. However, even in these cases, the devices only allow the total volume of power consumption to be ascertained, or they may issue warnings to prevent the contracted volume of power from being exceeded. In order to tackle the issue of reducing power consumption, it was first necessary to obtain an accurate breakdown of how much power was being used in each particular area. In other words, we needed to be able to visualize the amount of power being consumed. Safety, was also not being managed very rigorously. Even now, tunnel construction sites often use a 'name label' system for managing entry into the work site. Specifically, red labels with white reverse sides that bear the workers' names on both sides are displayed at the tunnel work site entrance. The workers themselves then flip the name label to the appropriate side when entering or exiting from the work site to indicate whether or not they are working inside the tunnel at any given time. If a worker forgets to flip his or her name label when entering or exiting from the tunnel, management cannot be performed effectively. In order to tackle the challenges mentioned above, Zenitaka decided to build a system that could improve the safety of tunnel construction as well as reduce the amount of power consumed. In other words, this new system would facilitate a clear picture of which workers were working in each location at the mountain tunnel construction site, as well as which processes were being carried out at those respective locations at any given time. The system would maintain the safety of all workers while also carefully controlling the electrical equipment to reduce unnecessary power consumption. Having decided on the concept, our next concern was whether there existed any kind of robust hardware that would not break down at the construction work site, that could move freely in response to changes in the working environment, and that could accurately detect workers and vehicles using radio frequency identification (RFID). Given that this system would involve many components that were new to Zenitaka, we decided to enlist the cooperation of E.I.Sol Co., Ltd. ('E.I.Sol') as our joint development partner, as they had provided us with a highly practical proposal.

Splunk Partnership Ties Together Big Data & IoT Services
Splunk was faced with the need to meet emerging customer demands for interfacing IoT projects to its suite of services. The company required an IoT partner that would be able to easily and quickly integrate with its Splunk Enterprise platform, rather than allocating development resources and time to building out an IoT interface and application platform.

Bridge monitoring in Hamburg Port
Kattwyk Bridge is used for both rail and road transport, and it has played an important role in the Port of Hamburg since 1973. However, the increasing pressure from traffic requires a monitoring solution. The goal of the project is to assess in real-time the bridge's status and dynamic responses to traffic and lift processes.

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.

Selling more with Whirlpool
Whirlpool wanted to add connectivity to appliances and transform the company's relationship with customers. Traditionally, Whirlpool interaction with customers was limited to purchases made once every ten years. Connected washer and dryers provide exciting new features like remote management of start times and inter-machine communication.

SAS® Analytics for IoT: Smart Grid
Companies face falling revenues, rising infrastructure costs, and increasing risk of outages caused by inconsistent energy production from renewable sources. Less money is coming in as more people and organizations take steps to curb their energy use. Utilities are paying more to maintain and build infrastructure due to increasing complexity, resulting from the rising number of intermittent and variable renewable energy sources connected in the distribution grid.
