Abstract
An inverter communication system is provided. The system includes a plurality of inverters connected to each other through a communication line, and assigned with different original identifiers for mutual distinction, wherein each of the plurality of inverters: receives a data frame transmitted through a previous inverter; selectively transmits the received data frame to a subsequent inverter; generates a data frame to be transmitted when data to be transmitted to a specific inverter occur; and transmits the generated data frame to a subsequent inverter.
Claims10
An inverter communication system comprising:
- a plurality of inverters connected to each other through a communication line, and assigned with different original identifiers for mutual distinction,
- wherein each of the plurality of inverters is configured to:
- generate a data frame to be transmitted when data to be transmitted to a specific inverter occur;
- transmit the generated data frame to a subsequent inverter;
- determine whether a data frame is received via a first adjacent inverter,
- wherein the received data frame comprises destination information including an original identifier of an inverter where the data frame arrives finally and departure information including an original identifier of an inverter that generates and transmits the data frame initially;
- confirm the destination information included in the received data frame when the data frame is received;
- determine whether the confirmed destination information is identical to its own original identifier;
- drive a motor using data in the received data frame when the confirmed destination information is identical to its own original identifier;
- confirm the departure information included in the received data frame when the confirmed destination information is not identical to its own original identifier;
- determine whether the confirmed departure information is identical to its own original identifier;
- delete the received data frame when the confirmed departure information is identical to its own original identifier;
- and
- transmit the received data frame to a second adjacent inverter when the confirmed departure information is not identical to its own original identifier.

An inverter comprising:
- a data reception unit receiving a data frame transmitted via a previous inverter;
- a data transmission unit selectively transmitting the received data frame to a subsequent inverter;
- a data frame generation unit generating a data frame to be transmitted to a specific inverter when data to be transmitted to the specific inverter occur;
- and
- a control unit configured to:
- cause selective transmission of the data frame to a subsequent inverter;
- determine whether a data frame is received from a first adjacent inverter,
- wherein the received data frame comprises destination information including an original identifier of an inverter where the data frame arrives finally and departure information including an original identifier of an inverter that generates and transmits the data frame initially;
- confirm the destination information included in the received data frame when the data frame is received;
- determine whether the confirmed destination information is identical to its own original identifier;
- drive a motor using data in the received data frame when the confirmed destination information is identical to its own original identifier;
- confirm the departure information included in the received data frame when the confirmed destination information is not identical to its own original identifier;
- determine whether the confirmed departure information is identical to its own original identifier;
- delete the received data frame when the confirmed departure information is identical to its own original identifier;
- and
- cause transmission of the received data frame to a second adjacent inverter when the confirmed departure information is not identical to its own original identifier.

A communication method of an inverter, the method comprising:
- receiving a data frame transmitted from a first adjacent inverter, wherein the received data frame comprises destination information including an original identifier of an inverter where the data frame arrives finally and departure information including an original identifier of an inverter that generates and transmits the data frame initially;
- confirming the destination information included in the received data frame when the data frame is received;
- determining whether the confirmed destination information is identical to its own original identifier;
- driving a motor using data in the received data frame when the confirmed destination information is identical to its own original identifier;
- confirming the departure information included in the received data frame when the confirmed destination information is not identical to its own original identifier;
- determining whether the confirmed departure information is identical to its own original identifier;
- deleting the received data frame when the confirmed departure information is identical to its own original identifier;
- and
- transmitting the received data frame to a second adjacent inverter when the confirmed departure information is not identical to its own original identifier.
