Abstract:
1. A system for controlling a power line network, comprising: a control unit device, generating a first temporary identification (ID), and broadcasting a first query message in the power line network, wherein the first query message comprises the first temporary ID; when the control unit device does not receive a response/warning message corresponding to the first query message within a predetermined time, the control unit device sets a control network identification (CNID) of the control unit device to the first temporary ID; when the control unit device receives the response/warning message corresponding to the first query message within the predetermined time, the control unit device generates a second temporary ID, and broadcasts a second query message in the power line network, wherein the second query message comprises the second temporary ID, and the second temporary ID is different to the first temporary ID; an agent device, wherein the control unit device coordinates the agent device so that the agent device and the control unit device synchronously broadcast a plurality of discovery messages in the power line network, and each of the discovery messages comprises a CNID of the device sending the discovery message; and one or more network devices, receiving all of the discovery messages from the power line network, and setting the CNID of the discovery message with the strongest received signal strength as a CNID of the one or more network devices.
