Digi mesh network connects island street lights and remote electric reclosures
MINNETONKA, Minn. (Oct. 11, 2011) - Digi International (NASDAQ: DGII) today announced that CIMCON Software, Inc. is using XBee-PRO® ZigBee modules to connect its LightingGale™ street light management system on St. John, U.S. Virgin Islands. The system will also be used by the Virgin Island Water and Power Authority (VIWAPA) to connect remote electric reclosures which transmit power to homes and businesses.
St. John Island street lights are connected to the LightingGale system via plug-and-play Street Light Controllers (SLCs) that easily replace a traditional photocell. The SLCs communicate with each other and to a gateway through a mesh network created by XBee-PRO ZigBee modules. The gateways then connect the mesh network to CIMCON’s LightingGale management software where customers can easily access street light energy consumption data and control individual lights.
“We needed something that was easy to use and could withstand the harsh elements,” said Anil Agrawal, Director, CIMCON. “We also needed a solution that could traverse great ranges and dense brush. Digi offers the industry’s leading ZigBee products, and we felt confident that its XBee® modules would prove reliable under the severe island conditions.”
There are more than 650 SLCs attached to street lights scattered across the island. Because of the ruggedness and range of Digi’s XBee-PRO ZigBee modules, CIMCON was able to establish full communication across the entire island by deploying only two gateways.
“We only have two gateways covering 28 square miles of land,” Agrawal said. “I was pleasantly surprised that the Digi modules could cover the entire island with only two gateways, especially given the difficult island terrain.”
“The mesh network will be used for more than street light control,” Agrawal adds. “For example, it will allow VIWAPA staff to easily monitor and control approximately 60 reclosures remotely. It will also enable users to set up alarms and notifications regarding energy consumption and faults on their smart phones, thereby improving customer satisfaction while reducing energy consumption.”
