NameDescription
Power gatewayThere are different types of gateways in different network structures. The HAN network includes HAN power gateway equipment and smart meter equipment; the LAN network includes the LAN power gateway equipment; and the WAN network includes the WAN power gateway equipment.
HAN networkDevices in a home area network (HAN) share resources through public communication networks (such as Ethernet) or wireless connections (such as WIFI, Bluetooth low energy, ZigBee, and IEEE 802.15.4). The smart meter of each home local area network is used as the entrance and exit of electric energy control, and the electricity consumption in the home network is collected and controlled through the smart meter.
LAN networkThe local area network (LAN) is larger than the HAN network communication range from the perspective of network information communication. The LAN network is an alliance blockchain composed of HAN power gateways, which can store data. In the LAN consortium blockchain network, the HAN power gateway node collects and stores information from the smart meters in HAN.
WAN networkFrom the perspective of network communication, the wide-area network (WAN) has a larger communication range than LAN. In the wide-area network, the power gateway in the LAN is used as a node to form an alliance blockchain. The LAN power gateway in the WAN consortium blockchain network completes data collection and storage in the LAN network.
