Master-slave equipment self-adaption method of power line modem

Abstract

The invention provides a master-slave equipment self-adaption method of a power line modem, which comprises the following steps: a central processing unit sending an inquiry data packet, and if an acknowledgement data packet is received, judging the power line modem to be slave equipment; the central processing unit detecting the connectivity of the Ethernet interface through the Ethernet interface module, and if no Ethernet interface is connected with the home gateway / router, the central processing unit judging that the power line modem is slave equipment; the central processing unit sendinga preset message through the internet access communication module, and if a response message is received, judging the power line modem to be main equipment; and in any step, after the power line modemcompletes judgment of the master equipment and the slave equipment, correspondingly updating configuration information of the master equipment or the slave equipment and storing the configuration information in a memory. According to the master-slave equipment self-adaption method provided by the invention, the power line modem can be self-adapted to the node role of the master equipment or the slave equipment in the power line network, the use difficulty of a user is reduced, and the production process is simplified.

Description

technical field [0001] The invention relates to the technical field of communication and network, in particular to a master-slave device self-adaptation method of a power line modem. Background technique [0002] The power line modem is a broadband Internet access terminal device, which has the advantages of stable transmission, no need for wiring, plug and play, etc., and cooperates with dual-band WIFI and smart roaming to perfectly solve the pain point of home network instability. It is a very important basic network device for home networks . The power line modem has two roles of master device and slave device. When using it, the user needs to distinguish the master device and the slave device from the appearance of the product, that is, the user needs to make human judgments when using it, which increases the complexity of use. If the connection is wrong (such as connecting the Ethernet interface of the slave device to the router), it will cause network failure; at the ...

The power line modem has two roles of master device and slave device. When using it, the user needs to distinguish the master device and the slave device from the appearance of the product, that is, the user needs to make human judgments when using it, which increases the complexity of use. If the connection is wrong (such as connecting the Ethernet interface of the slave device to the router), it will cause network failure; at the same time, it is not convenient for the merchant to produce uniformly, which increases the production complexity and production cost
