Networking communication method of electricity consumption information acquisition system based on WIA-PA technology

Abstract

The invention relates to a networking communication method of an electricity consumption information acquisition system based on WIA-PA technology, belonging to the technical field of electricity consumption information acquisition. The method comprises the following steps that: S1, a gateway device assign corresponding IPv6 address for the whole electricity consumption information acquisition network according to device type of each node; S2, in combination with a networking method of the WIA-PA technology and a communication architecture of the electricity consumption information acquisition network, a backbone network and corresponding sub-networks, supporting IPv6 message transmission, of the electricity information acquisition system are established; S3, the gateway device realizes acquisition of electricity consumption information of users through the established electricity consumption information acquisition network. By the method, the WIA-PA network with IPv6 message transmission capability and the electricity consumption information acquisition system are effectively combined together, IPv6 address property of user nodes in wireless meter reading is realized, meanwhile, by a hierarchical routing search strategy, data acquisition success rate of a wireless network in the electricity consumption acquisition system is improved, problems, such as communication delay, are solved, and application demonstration of domestic industrial wireless WIA-PA standard in the filed of electricity consumption information field is promoted.

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
