Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing.

[0017] To facilitate the description of the scheme, the table below explains some of the terms and definitions of the scheme.

[0018]

[0019]

[0020] HomePlugAV adopts a point-to-multipoint bidirectional tree network. "One point" refers to CCo, and "multipoint" refers to multiple STAs. CCo and multiple STAs can perform bidirectional and concurrent carrier communication. In general, STAs can communicate directly with CCo, but in some special cases, such as harsh power line noise environment or too far away from nodes, STAs cannot establish communication with CCo directly. These STAs are called HSTAs. It needs the relay function of PSTA to communicate with CCo indirectly. In addition, the establishment of communication between STAs is not allowed by default, unless the relationship between the two STAs is relaying and being relayed. Each registered STA is assigned ...

Abstract

The invention relates to a low-voltage grid meter reading data collecting method based on HomePlug AV. A system is powered on, carrier node ammeters send signals A for requiring to be endowed with terminal device identification to a broadband PLC chip of a concentrator, the broadband PLC chip sends terminal device identification information, the carrier node ammeters send signals B for requiring to obtain an encryption secret key to the broadband PLC chip, the broadband PLC chip sends member secret key information, the carrier node ammeters successfully log in and get online, a HomePlug AV local area network is formed, the concentrator uplinks through the HomePlug AV local area network to collect parallel meter reading data of the carrier node ammeters, and the concentrator uplinks through a GPRS or CDMA or Ethernet to convey parallel meter reading data to a master station. By means of an internet access and a broadband PLC, the uplink and downlink of an end module of the concentrator are enlarged, parallel meter reading becomes possible, and the meter reading speed is greatly increased.

Description

technical field [0001] The invention relates to a low-voltage power grid meter reading data acquisition method, in particular to a low-voltage power grid meter reading data acquisition method based on HomePlug AV, which belongs to the field of electric power monitoring. Background technique [0002] BPL (Broadband over power lines) is a technology that allows Internet data to be transmitted over power lines. People often refer to BPL as power line communication PLC. Broadband over Power Line communication (BPL), referred to as BPL, refers to power line carrier communication with a bandwidth limited between 2-30 MHz and a communication rate usually above 1 Mbps. Power line communication technology uses the existing solid and reliable power lines as the medium of information transmission, and transmits analog or digital signals through carrier waves. The power line can be used directly without rewiring, the networking is simple and fast, the cost is relatively low, the appli...
