关于客户
湾区空气质量管理区（Air District）是加州立法机构于 1955 年创建的一个区域性空气污染控制机构。空气区监管旧金山湾周围 9 个县的固定空气污染源，目标是实现维持州和国家环境空气质量标准。空气区负责与环境正义社区合作，制定和实施“以社区为中心”的战略，以减少受空气污染影响最严重的社区的暴露。西奥克兰被航空区选为第一个根据 AB617 进行评估的社区，因为它靠近周围的高速公路、奥克兰港、主要铁路站和重工业。
挑战
湾区空气质量管理区（Air District）成立于 1955 年，是美国第一个区域性空气污染控制机构。尽管自实施以来区域空气质量显着改善，但旧金山湾区的一些社区由于靠近高速公路、繁忙的配送中心和大型工业设施等污染源，仍然面临较高的污染水平。 2017 年，加州议会通过了第 617 号议会法案 (AB617)，以减少受空气污染影响最严重的社区的暴露。西奥克兰被选为第一个根据 AB617 进行评估的社区，因为它靠近周围的高速公路、奥克兰港、主要铁路站和重工业。空气区与当地环境正义倡导者、社区成员、行业代表和其他利益相关者合作，成立了指导委员会来制定社区减排计划，称为西奥克兰行动计划。该行动计划的目标是通过采取有针对性的缓解策略，减少西奥克兰空气污染对健康的影响。
解决方案
Air District 与 Citilabs®（现属于 Bentley Systems）签订合同，获取阿拉米达县和康特拉科斯塔县的 Streetlytics 数据。 Streetlytics 是排放清单和建模分析所需的详细道路远程信息处理的唯一提供商。与其他来源结合使用的数据集用于制定详细的道路排放清单，包括准确的地理空间道路网络、每个道路段按季节、星期几和一天中的时间划分的平均车辆数、每个道路段每小时的平均车辆速度，以及巷道段特征。利用 Streetlytics 数据与 EMFAC2017 的排放因子和其他补充数据相结合，空气区能够制定详细的排放清单，其中包括沿西部每个道路连接的行驶废气、行驶损失、轮胎磨损、制动器磨损和重新悬浮的道路灰尘奥克兰。 2020 年，Air District 通过获取完整的旧金山湾区九县数据集扩大了 Streetlytics 数据的使用。这将使空气区能够在未来五年内根据 AB617 计划为湾区选定的其余社区制定详细的道路排放清单。

Turning A Stadium Into A Smart Building
Honeywell created what it called the “intelligent system” for the National Stadium in Beijing, China, turning the venue for the opening and closing events at the 2008 Summer Olympics into a “smart building.” Designed by highly controversial artist Ai Weiwei, the “Bird’s Nest” remains one of the most impressive feats of stadium architecture in the world. The 250,000 square meter structure housed more than 100,000 athletes and spectators at a time. To accommodate such capacity, China turned to Honeywell’s EBI Integrated Building Management System to create an integrated “intelligent system” for improved building security, safety and energy efficiency.

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.

IoT-based Fleet Intelligence Innovation
Speed to market is precious for DRVR, a rapidly growing start-up company. With a business model dependent on reliable mobile data, managers were spending their lives trying to negotiate data roaming deals with mobile network operators in different countries. And, even then, service quality was a constant concern.

Buoy Status Monitoring with LoRa
The Netherlands are well-known for their inland waterways, canals, sluices and of course port activities. The Dutch Ministry of Infrastructure indicates that there are thousands of buoys and fixed items in and near water environments that would profit from IoT monitoring. One of the problems with buoys for example, is that they get hit by ships and the anchor cable breaks. Without connectivity, it takes quite some time to find out that something has happened with that buoy. Not to mention the costs of renting a boat to go to the buoy to fix it. Another important issue, is that there is no real-time monitoring of the buoys at this moment. Only by physically visiting the object on the water, one gains insight in its status.
