Embodiment Construction

[0050] 1. Preliminary conditions

[0051] The networking only considers concentrators, carrier ammeters and collectors, and collectors and carrier ammeters are collectively referred to as terminals. The concentrator has the functions of receiving and sending messages, and plays a leading role in communication; the collector and carrier meter have relay functions, and have the functions of receiving and forwarding messages; both concentrators and terminals have the ability to analyze electrical distances. The electrical distance is a parameter used to measure the reliability of communication in the power line communication network. The shorter the electrical distance, the higher the reliability of communication, and vice versa. The electrical distance can be measured by the signal-to-noise ratio of the communication signal. The higher the signal-to-noise ratio, the shorter the electrical distance, and vice versa.

Abstract

The invention discloses a low-voltage power line communication network constructing method for a power meter reading system. A constructed low-voltage power line communication network comprises a concentrator, a carrier power meter and a collector; wherein the collector and the carrier power meter are used as terminals for each level; the low-voltage power line communication network construction is completed in three steps: logical layering, communication topology construction and communication routing selection; the logical layering comprises establishing logical layers according to the length of the electrical distance between the terminals in each level, and respectively marking and attributing the collector and the carrier power meter into different levels; and the communication topology construction comprises storing the IP of the two terminals and the electrical distance into the concentrator under the condition that the electrical distance of the two terminals between the upperlevel and the lower level is less than or equal to L, thereby optimizing the network topology. In addition, the invention adopts a communication routing reconstruction method for the carrier power meter with failure, thereby realizing the timely updating and troubleshooting of the network topology.

Description

technical field [0001] The invention relates to a low-voltage power line communication networking method, in particular to a low-voltage power line communication networking method used in a power meter reading system. Background technique [0002] The construction of the electric meter reading system is the basis for the implementation of the ladder electric ladder, which can realize the effective management and rational utilization of electric energy, reduce the loss of electric energy, and reduce the trouble caused by manual meter reading. The power meter reading system that has been implemented in our country, from the actual effect point of view, mainly has the problem of low reading success rate, which is mainly due to the immaturity of the current low-voltage carrier communication networking technology. [0003] The current low-voltage power line networking methods that have been implemented have the following disadvantages: the networking method is complex, requiring ...
