The street lights at St. John Island are connected to the LightingGale system via plug-and-play Street Light Controllers (SLCs) that communicate with each other and to a gateway through a mesh network created by XBee PRO ZigBee modules.
When the gateways connect the mesh network to CIMCON’s LightingGale management software it allows customers to easily access street light energy consumption data and control individual lights.
According to a release, there are over 650 SLCs attached to street lights scattered across the island but thanks to the ruggedness and range of Digi's XBee PRO ZigBee modules, CIMCON could easily establish full communication across the entire island by deploying only two gateways.
“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.”
CIMCON is not the only one to use these modules and this 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.
“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.”
