Problems solved by technology
On the one hand, the anti-interference ability of G3-PLC technology is not unlimited. For example, the design of electrical equipment is not standardized, and the interference of power line noise is serious, which will affect the performance of carrier communication. Noise and other serious interference
On the other hand, the network layer of the G3-PLC protocol uses the LOADng protocol. As a responsive protocol, a large number of data packets such as RREQ\RREP\RERR will be generated to maintain the network when the network is abnormal. For example, the routing module may continuously generate RREQ packets and cause intermediate The forwarding node can only forward continuously, the receiving end receives a large number of RREQ messages and has to generate a large number of repeated RREP messages, and too many RERR messages are generated during path repair, resulting in more RREQ messages. Network congestion or even memory exhaustion
[0004] Power line noise and a large number of network control messages such as RREQ\RREP\RERR will adversely affect the efficiency and reliability of network communication, increase the maintenance difficulty and workload of staff, and consume a lot of manpower and material resources

Description
technical field [0001] The invention relates to the technical field of carrier communication, in particular to a concentrator-based G3-PLC network diagnosis and maintenance method. Background technique [0002] G3-PLC carrier technology is mainly used in power collection systems. It adopts OFDM modulation, which can automatically evaluate the quality of the channel, and select the sub-carrier channel with better channel for signal transmission. The more sub-carriers, the greater the bandwidth and the faster the transmission speed. G3-PLC technology has strong anti-interference ability, fast transmission speed, and can be interconnected. The equipment installation is simple and only needs to be connected to the power line environment. Therefore, G3-PLC technology is widely used in power collection systems. [0003] But the application of G3-PLC in the prior art has its limitations. On the one hand, the anti-interference ability of G3-PLC technology is not unlimited. For exam...
