挑战
在美洲和欧洲，电力由分布在广大地区的许多私人发电厂提供。优化配电和输电以满足市场需求始终是一项挑战，特别是因为电力供应商需要监控数据使用情况并结合发电、配电和输电数据。部署远程无线自动抄表将使电力供应商能够更好地衡量和响应市场需求，并优化分配能源分配以控制不断上升的能源成本和服务中断。该应用程序中的客户是一家合作拥有的电力服务公司，截至 2007 年，其资产超过 8.16 亿美元，能源销售额接近 430 万兆瓦时。它在美国西部提供电力并提供其他管理服务。该公司提供电源选项的领导和管理，并继续实施日益复杂的电源管理技术和创新技术，使该地区的公用事业能够以稳定的价格提供低成本的电源选项。系统要求• 在广大地区进行远程无线传输（卫星、GPRS、WCDMA、微波等）。 • 需要在低带宽网络环境中传输数据。 • 自我监控连接状态，当连接失败时，系统会重新启动以恢复通讯。

解决方案
设计良好的通信结构对于有效监控配电非常重要。客户使用电流互感器和电表来测量已用电量。当电流流过电流互感器时，仪表会发出脉冲输出，而 Moxa 的 ioLogik E2212 用于跟踪已使用的能量。此外，ioLogik E2212 的主动报告功能有助于自动传递事件消息，并每隔几秒将计数器值发送回中央站点，以供生成和分发参考。这种远程监控系统通常安装在偏僻的地方，使得维护既困难又昂贵。为确保通信系统稳定，ioLogik 的看门狗定时器用于监控连接状态。如果通信失败，ioLogik E2212 将向外部继电器计时器发送输出，该计时器将系统关闭五分钟，然后重新启动系统。除了主动消息和看门狗定时器之外，Moxa 的另一个主要优势是简单直观的 IF-THEN-ELSE Click&Go 控制逻辑，它可以帮助用户将编程时间从几天缩短到几分钟，同时也有助于将维护成本降至最低。产品解决方案： ioLogik E2212 智能以太网远程 I/O，带 8 个 DI、8 个 DO、4 个 DIO

IoT Solutions for Smart City | Internet of Things Case Study
There were several challenges faced: It is challenging to build an appliance that can withstand a wide range of voltage fluctuations from as low at 90v to as high as 320v. Since the device would be installed in remote locations, its resilience was of paramount importance. The device would have to deal with poor network coverage and have the ability to store and re-transmit data if networks were not available, which is often the case in rural India. The device could store up to 30 days of data.

Automation of the Oguz-Gabala-Baku water pipeline, Azerbaijan
The Oguz-Gabala-Baku water pipeline project dates back to plans from the 1970’s. Baku’s growth was historically driven by the booming oil industry and required the import of drinking water from outside of the city. Before the construction of the pipeline, some 60 percent of the city’s households received water for only a few hours daily. After completion of the project, 75 percent of the two million Baku residents are now served around the clock with potable water, based on World Health Organization (WHO) standards. The 262-kilometer pipeline requires no pumping station, but uses the altitude differences between the Caucasian mountains and the capital to supply 432,000 m³/d to the Ceyranbatan water reservoir. To the people of Baku, the pipeline is “the most important project not only in 2010, but of the last 20 years.”

GPRS Mobile Network for Smart Metering
Around the world, the electricity supply industry is turning to ‘smart’ meters to lower costs, reduce emissions and improve the management of customer supplies. Smart meters collect detailed consumption information and using this feedback consumers can better understand their energy usage which in turn enables them to modify their consumption to save money and help to cut carbon emissions. A smart meter can be defined in many ways, but generally includes an element of two-way communication between the household meter and the utility provider to efficiently collect detailed energy usage data. Some implementations include consumer feedback beyond the energy bill to include online web data, SMS text messages or an information display in consumers’ premises. Providing a cost-effective, reliable communications mechanism is one of the most challenging aspects of a smart meter implementation. In New Zealand, the utilities have embraced smart metering and designed cost effective ways for it to be implemented. The New Zealand government has encouraged such a move to smart metering by ensuring the energy legislation is consistent with the delivery of benefits to the consumer while allowing innovation in this area. On the ground, AMS is a leader in the deployment of smart metering and associated services. Several of New Zealand’s energy retailers were looking for smart metering services for their residential and small business customers which will eventually account for over 500,000 meters when the multi-year national deployment program is concluded. To respond to these requirements, AMS needed to put together a solution that included data communications between each meter and the central data collection point and the solution proposed by Vodafone satisfied that requirement.

NB-IoT connected smart meters to improve gas metering in Shenzhen
Shenzhen Gas has a large fleet of existing gas meters, which are installed in a variety of hard to reach locations, such as indoors and underground, meaning that existing communications networks have struggled to maintain connectivity with all meters. The meter success rate is low, data transmissions are so far unstable and power consumption is too high. Against this background, Shenzhen Gas, China Telecom, Huawei, and Goldcard have jointly trialed NB-IoT gas meters to try and solve some of the challenges that the industry faces with today’s smart gas meters.

British Gas Modernizes its Operations with Innovative Smart Metering Deployment
The UK government has mandated that smart meters are rolled out as standard across Great Britain by end of 2020, and this roll-out is estimated to create £14 billion in net benefits to the UK in consumer energy savings and lower energy generation demand, according to the Oxford Economics report, “The Value of Smart Metering to Great Britain.” While smart-metering systems have been deployed in many countries, the roll-out in Great Britain is unique because it is led by energy retailers, who have responsibility for the Electricity and Gas meters. The decision to have a retailer-led roll out was made by DECC (Department of Energy and Climate Change) to improve customer experience and drive consumer benefits. It has also led to some unique system-level requirements to support the unique local regulatory model.
