A network communication method for power consumption information collection system based on wia-pa technology

Abstract

The invention relates to a network communication method for a power consumption information collection system based on WIA-PA technology, and belongs to the technical field of power consumption information collection. The method includes the following steps: S1: the gateway device allocates a corresponding IPv6 address for the entire power consumption information collection network according to the device type of each node; S2: combining the networking method of WIA-PA technology and the power consumption information collection network communication architecture, Construct the backbone network and corresponding subnet of the electricity consumption information collection system that supports IPv6 message transmission; S3: The gateway device collects electricity consumption information of power users through the constructed electricity consumption information collection network. This method effectively combines the WIA-PA network with IPv6 message transmission capability with the power consumption information collection system, realizes the IPv6 addressing of user nodes in wireless meter reading, and uses the hierarchical routing search strategy to improve the wireless network in use. Problems such as data collection success rate and communication delay in the electricity information collection system have promoted the application demonstration of the domestic industrial wireless WIA‑PA standard in the field of electricity information collection.

Description

technical field [0001] The invention belongs to the technical field of electricity consumption information collection, and relates to a network communication method of a power consumption information collection system based on WIA-PA technology. Background technique [0002] The existing power consumption information collection system includes master station, substation, smart meter and communication network among them. The substations mainly include concentrators and collectors. In a layered system network, the local network (LAN) connects the smart meters and the concentrator, and the concentrator is connected to the main station through the wide area network (WAN). The master station is usually deployed in a centralized manner according to a province or a certain region. The master station system communicates with the concentrator to obtain the smart meter collection task, and the concentrator collects data during the collection process. In this process, both the uplink...

The Chinese patent application number is: 201210518304.8, and the name is: An optical wireless networking communication system and method suitable for electricity information collection. This invention uses optical wireless networking for communication, and separates the wireless base station into a baseband unit and a radio frequency unit. , to realize remote wireless signals, greatly improving the transmission efficiency of data information in the distribution network, but due to equipment cost factors, this technology is not applicable in the power grid

The Chinese patent application number is: 201410076180.1, and the name is: Networking method for self-organized network of wireless power consumption information collection. This method realizes the rapid establishment of a large tree-shaped power consumption collection network after the nodes in the network are powered on, and is effective in combination with the corresponding frequency modulation technology. It solves the problem of local interference in the network, but for the wireless power collection network, if the intermediate node in the constructed tree network fails, it will inevitably cause the successor nodes to be affected
