Overview:

The communication of the system adopts a distributed architecture, which is divided into two layers:

The upper layer is between the power management center and the concentrator, and the data collection of the upper layer adopts a star structure, that is, one power management center manages the concentrators of N stations.

The bottom layer is between the concentrator and the power carrier meter, and the station area is used as the management unit. The data collection of the bottom layer uses the power line as the transmission medium. It has the advantages of convenient installation, high reliability, good safety and strong maintainability.

Main features:

• Reading data: The concentrator reads the meter data in the station area during the meter reading period.

• Setting parameters: can be set by the background system or PDA.

• Store data: The concentrator stores the read data.

• Relay function: The concentrator can automatically activate the relay according to the learning result to realize the relay meter reading

• Freeze function: The concentrator can freeze the meter reading of the meter in the station area according to the background settings.

• Remote monitoring: Support the background system to remotely monitor the meter in real time and analyze the situation of the meter.

• Timing function: system timing can be realized.

• Interactive commands: Support the background system to perform command-level interactive command operations.
