Embodiment Construction

[0041] figure 1 Shows a schematic flow chart of a method 100 for controlling access to meter equipment according to an embodiment of the present application. The method 100 can be applied to a meter reading system deployed using AMI, involving the master station, the collector, and the meter equipment. Inter-communication, where the metering device can be a smart meter supporting PLC technology, or a smart water meter.

[0042] Optionally, the collector in this embodiment of the present application may be a data concentrator unit (Data Concentrator Unit, DCU for short). In the embodiment of the present application, a smart electric meter supporting PLC technology (hereinafter referred to as electric meter) is taken as an example to illustrate the technical solution of the present application, but it is not limited thereto. The electric meter and the collector are connected through the power line, and the PLC protocol is used for communication, and the data transmission is car...

Abstract

An embodiment o the invention provides a method of controlling meter equipment access. The method comprises the following steps that a first collector receives a first access network request message sent by first meter equipment, wherein the first access network request message does not include an identification of the collector; the first collector sends query information to a main station, wherein the query information includes the identification of the collector and an identification of the first meter equipment; the first collector receives response information sent by the main station according to the query information; and the first collector determines to receive or reject network access of the first meter equipment according to the response information so that the meter equipment accesses to an assigned collector. A probability for the meter equipment to generate crosstalk is effectively reduced, system installation disposition efficiency is increased and maintenance cost is reduced. Besides, broadcast network access messages sent by a DCU on a line can be effectively decreased and line interference is reduced.

Description

technical field [0001] The present application relates to the field of communications, and in particular to a method and device for controlling the access of meter equipment. Background technique [0002] In existing advanced metering infrastructure (Advanced Metering Infrastructure, AMI) systems at home and abroad, if the meter reading system wants to collect the data of the power line communication (Power Line Communication, PLC) meter, it needs the master station, the collector and the PLC meter. communication between each other. PLC ammeters and collectors transmit data through the existing power lines, using the PLC power line carrier protocol. In the power line network, the physical wiring is a tree topology structure, and the transformer is the supply source of a station area, which splits out multiple power lines, and the nodes on each power line share the medium. Based on the characteristics of the power line network, the topology structure of the entire network i...
