Communication Mode

Communication Networking

The device supports professional power communication networking.
  • Uplink networking

    Networking between the device and a front-end processor is uplink networking.

    A DCU gateway can communicate with a front-end processor through 3G or FE/SFP. The front-end processor delivers a command to the DCU to obtain real-time data from the device for device monitoring.

  • Downlink networking

    Networking between the device and meters is downlink networking.

    A DCU gateway can communicate with meters through PLC, RS485, RF, and ZigBee channels.

    • PLC technology can use existing power lines as transmission lines, reducing network investment.
    • RS485 cabling applies to the areas where meters are deployed in a centralized manner. RS485 also supports the Device Language Message Specification (DLMS) protocol of IEC 62056 and the Modicon Communication Bus (Modbus) protocol.
    • ZigBee/RF technology applies to the areas where meters are sparsely deployed within 2 km.

Communication Data

The device can respond to communication requests sent by a front-end processor and initiate communication requests to a front-end processor.

The device can respond to the following types of communication requests sent by a front-end processor:

  • Device data query

    Device data includes the device status data, historical meter data, and event data stored in the device. When data to be queried does not exist, the device returns invalid data to the front-end processor.

  • Real-time meter data reading

    After receiving a real-time meter data reading instruction from the front-end processor, the device sends the instruction to a specified meter and sends the result obtained from the meter to the front-end processor.

  • Event reporting

    The device continuously detects events generated on itself and connected meters. When the device detects an event, it determines whether the event is a major event according to the configuration. If so, the device reports the event to the front-end processor, which then sends an acknowledgement packet to the device.

  • Data forwarding

    After receiving a data forwarding instruction from the front-end processor, the device sends the content to be forwarded to a specified meter and sends the result obtained from the meter to the front-end processor.
