Embodiment Construction

[0031] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] refer to figure 2 As shown, the present invention provides a power carrier communication method, which includes the following steps:

[0033] S1) The main site sends a beacon or message to each sub-site; and

[0034] S2) Each sub-site forwards the beacon or the message, and receives the beacon and the message forwarded by the adjacent sub-site, and the sub-site creates or The partnership table is updated, and the sub-site can send beacons or messages to the main site through other sub-sites in the partnership table.

[0035] That is, in the power carrier commu...

Abstract

The present invention provides a power carrier communication method, which is characterized in that it comprises the following steps: S1) the main site sends a beacon or a message to each sub-site; and S2) each sub-site forwards the beacon or the message, And receive the beacon and the message forwarded by the adjacent sub-site, the sub-site creates or updates the partnership table according to the received beacon or the message, and the sub-site can pass the partnership table Other sub-sites in the network send beacons or packets to the main site. According to the power carrier communication method provided by the present invention, the communication is reliable and the networking efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a power carrier communication method. Background technique [0002] Power line communication (PLC) is a unique communication method for power systems. Power line communication refers to the technology of using existing power lines to transmit analog or digital signals at high speed through carrier waves. [0003] In the existing power carrier scheme, the CCO (Central Coordinator) is mainly used to trigger the layer-by-layer STA (Station site ) network access request to complete the entire networking process, the CCO needs to allocate a TEI (Terminal Equipment Identifier) ​​to the STAs that have already joined the network. refer to figure 1 As shown, when a first-level site is connected to the network, the CCO can arrange a beacon time slot to allow the newly-connected first-level site (that is, to become a Proxy Coordinator, PCO, proxy coordinator) to send a d...
