[0077] Please refer to Figure 2 , Figure 2 This is a flowchart illustrating a network information construction method for an AMI network topology separation method according to some embodiments of this application. According to embodiments of the present invention, multiple communication methods are set, and network information is constructed based on combinations of these multiple communication methods, specifically including:

[0078] S201 selects multiple communication methods based on AMI, including wireless communication and wired communication. Wireless communication methods include LoRa, NB-IoT, G3, PRIME and 3G / 4G, and wired communication methods include RS485 bus and Ethernet.

[0082] It should be noted that different communication technologies can be used to eliminate signal blind spots. For example, wireless technology (LoRa / NB-IoT) covers wide areas, while wired technology (RS485 / Ethernet) solves the problem of deep indoor coverage.

[0083] Reliability redundancy: Data transmission backup is achieved through heterogeneous communication links. When a certain type of communication fails, it automatically switches to the backup link. For example, G3-PLC power line communication and LoRa wireless communication form a dual-link redundancy.
