挑战
深圳燃气现有大量燃气表，安装在各种难以到达的位置，例如室内和地下，这意味着现有的通信网络难以与所有仪表保持连接。电表成功率低，数据传输至今不稳定，功耗过高。在此背景下，深圳燃气、中国电信、华为、金卡等联合试用NB-IoT燃气表，试图解决行业在当今智能燃气表面临的一些挑战。
解决方案
2017年3月，金卡与深圳燃气、中国电信、华为合作部署了多款智能燃气表，在800MHz频谱的不同场景和地点进行NB-IoT通信试验。
通过使用NB-IoT，深圳燃气、中国电信、金卡和华为能够利用标准化的数据收集和物联网平台，网络运营的整个端到端管理可以由燃气公司集中进行或移动运营商。作为试验的一部分，合作伙伴实施了一个新的智能燃气计量框架，允许在网络上快速推出新的应用程序。它托管在中国电信和华为联合开发的eCloud上，具有专门为中国天然气行业制定的数据结构。这意味着中国的天然气供应商及其合作伙伴可以利用这些新技术。
合作伙伴希望测试成功完成多个不同场景，包括预付费和后付费计费和支付、阀门控制、各种仪表参数更改、不同的通信配置和数据完整性保护。因此，该试验旨在测试多种不同的场景，并确保即使在难以到达的位置（例如金属表柜内或大型建筑物内）也能连接燃气表。
要测量支持 NB-IoT 的燃气表的目标被设计为严格且符合燃气行业性能要求的预期。其中包括超过 99% 的抄表成功率、按需进行抄表的能力以及即使在抄表接收到的信号非常微弱的情况下也能成功抄表。

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.

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.

SCADA Cyber Security Vulnerability Assessment
A U.S. power company employed regularly-recurring audits of various controls, systems and programs. However, when it came to a SCADA-based cyber security vulnerability assessment, the in-house audit team did not possess the specific combination of process control experience and cyber security risks. They realized they required a third-party expert with a unique combination of knowledge of the two worlds.
