Assume that the maximum number of hops in the network is 7 hops, and the average transmission hops of uplink meter reading messages is set to 4 hops. In this 5-minute period, the total amount of uplink business data transmission in the network is about 300×100×4= 1.2×10 5 byte ≈ 10 6 bits, so in the whole network meter reading process, the business throughput of the entire network is only about 10 6 bit / 5 minutes ≈ 3kbps level, the utilization efficiency of the physical layer rate is only 3kbps / 1Mbps=0.3%, obviously there is still a lot of room for improvement in the comprehensive utilization efficiency of network resources

Embodiment Construction
[0029] In order to make the above-mentioned and other objects, features and advantages of the present invention more obvious, the following specific embodiments of the present invention are given and described in detail in conjunction with the accompanying drawings.
[0030] like figure 1 As shown, the broadband high-speed carrier communication network of the power consumption information collection system will generally form a central coordinator (CCO) as the center and proxy coordinator (proxy node, PCO) as a relay agent, connecting all slave stations (STA) Multilevel associative tree network. As the central control node of the network operation, the central coordinator uses a superframe time slot structure based on the beacon period for network communication, and uses the beacon signal to maintain the synchronization and orderly operation of the entire network. In the "Technical Specification for Interconnection and Interconnection of Low-Voltage Power Line High-speed Carr...

A beacon signaling protocol design method for a broadband carrier communication network. On the basis of the original beacon signaling protocol, in the management message of the beacon signal, a multicast address definition message, the latest sequence number information of the multicast address and the group information are defined. When a node joins the network, the central coordinator assigns a short network address to each node and assigns a multicast address, and broadcasts the content of the multicast address to all nodes that have entered the network, and the node receives After the beacon signal is received, it will be parsed. If it contains the content of a multicast address, it will determine whether it already has the content of the multicast address. If not, it will save the content of the received multicast address, and if so, it will be received more recently. Sequence numbers of the received and saved multicast addresses. When the sequence number of the saved multicast address is lower than the sequence number of the newly received multicast address, the saved group is overwritten with the content of the new multicast address. The content of the broadcast address is updated to update the information content.
Description
technical field [0001] The invention belongs to the technical field of broadband carrier communication, and in particular relates to an improved method for a beacon signaling protocol of a broadband carrier communication network. Background technique [0002] After the 1990s, the low-voltage power line carrier communication technology was gradually applied in the automatic meter reading system of the electric energy meter. However, with the development of the collection business, the traditional narrowband power line communication technology has gradually been unable to meet the continuously increasing business needs of the power operating enterprises for data collection. [0003] In order to better meet the information collection business needs of the smart meter automatic carrier collection and reading system, China's two major power grid companies - China Power Grid Corporation (referred to as State Grid) and China Southern Power Grid Corporation (referred to as China Sou...
