A smart grid is an electrical grid which includes a variety of operation and energy measures ranging from meters to controllers for data collection. Operators rely heavily on the timely data report that collected from the dispersed controllers and the IP cameras to make the right decision during the remote monitoring of line status, threshold warning and fault location for smart grid operation. In this scenario, the UR32 cellular routers are widely used to minimize the cost of downtime and bring distributed sites online faster.

Hardware List

   UR32 Router (PoE /RS485)

  • Always-on M2M connectivity
  • Industrial-grade enclosure
  • Versatile and compact solution
  • Additional RS485 port, optional GPS and Wi-Fi support


Recently, Ursalink cooperated with The State Grid Corporation of China to fulfil a smart grid project successfully. The RS485 controllers, IP cameras and Ursalink cellular routers are working smoothly in smart grid.

From the below topology we can see, the additional RS485 serial port on UR32 cellular router connects with a controller through Modbus that allows for the conversion of the legacy protocol. Operators are able to receive alerts and make response expeditiously depending on the accurate data that transferred from router when abnormal situation arose from the lines. And through the PoE interface, the UR32 router provides an out-of-the-box, secure, managed LTE network for the connected IP camera.

Here, UR32 cellular router works as a data packet forwarder and delivers all information to the monitoring center via 4G LTE cellular network.
