挑战
Given its climate and geography, the Massachusetts coastline is particularly susceptible to massive snow storms and blizzards as well as the power outages that accompany them. When they lose power, the majority of the region’s signalized intersections remain offline until utility service is restored, which in some cases, can be days or weeks. The danger of icy and snow-covered intersections is compounded by dark signals, one of the most dangerous traffic scenarios. In March 2017, late winter storm Stella brought blizzard conditions to parts of Massachusetts, blanketing New England with 3 – 5 feet of snow, leaving 100,000 customers without power. As a result, every one of Newburyport’s conventional traffic cabinets failed when they lost utility power. New England is not alone. Extreme weather is causing a dramatic increase in major power outages, estimated to have increased tenfold since the mid-1980s.
关于客户
The Massachusetts Department of Transportation (MassDOT) is responsible for the transportation infrastructure in the state of Massachusetts, including highways, public transportation, and traffic management systems. In early 2017, at the request of McCain Distributor, Electric Light Company, Inc., MassDOT approved a solo intersection pilot to test McCain’s Low-Voltage ATC (Advanced Traffic Controller) Cabinet. The pilot was initially designed to test the low-voltage cabinet’s safety features for installers. MassDOT's role is crucial in ensuring the safety and efficiency of transportation systems, especially during extreme weather conditions that can lead to power outages and hazardous driving conditions.
解决方案
McCain’s 48VDC Low-Voltage ATC Cabinet was deployed at the intersection of Old Route 1 and Low Street in Newburyport, Massachusetts. This cabinet is designed to operate on low voltage, which dramatically extends the life of battery backups and improves safety for anyone with access to the cabinet, such as installers, technicians, and consultants. During the late winter storm Stella in March 2017, this intersection remained fully operational despite massive power outages throughout the region. The battery backup system of the McCain cabinet was still at 70% capacity ten hours after the storm, enough to run the intersection for two days fully actuated and an additional two weeks in flashing yellow mode. This solution not only ensured continuous operation of the traffic signals but also protected drivers, personnel, and the public from accidental contact with high-voltage wires in the event of a knockdown. The low-voltage operation also lowered personal protective equipment (PPE) requirements, making it safer for maintenance personnel.

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.

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.
