Self-organized network collaborative meter reading method

Abstract

The invention discloses a self-organized network collaborative meter reading method. Concentrators in each system use cascade interconnection to realize mutual transmission of data information, thus solving the problem of limited coverage when micro-power wireless communication is adopted, and the problem of serious interference due to shielding of buildings; and when a collector in a system is out of the own micro-power wireless communication coverage of the system due to remote location or serious interference caused by shielding of the buildings, but the collector is positioned in the signal coverage of another system staggered with the system, information data of an electric energy meter can be transmitted in a data information self-network supplying manner among the concentrators, so that the collection rate of a meter reading system is improved.

Description

Technical field [0001] The invention relates to the field of meter reading systems, and in particular to an automatic networked collaborative meter reading method. Background technique [0002] The meter reading system is a system in which the smart grid transcribes the data on the user-side meter and feeds the data back to the power supply department; whether the meter reading system can timely and accurately transcribe the data and feed it back to the power supply department has a key to the safe operation of the entire power grid. Important impact; therefore, the meter reading system is an indispensable key component of the entire smart grid. [0003] One of the meter reading systems is to use collectors and concentrators with micro-power wireless communication; the concentrator, collectors and a certain number of electric energy meters form a data acquisition network, which automatically collects each electric energy meter at a certain collection period. Data, generally the nu...

Problems solved by technology

When the micro-power wireless communication method is adopted, the concentrator has a built-in micro-power wireless communication module, and communicates with the collector in compliance with certain regulations; however, this communication method has the disadvantage of limited coverage. When the micro-power wireless communication signal coverage of the station area is within the signal coverage area of ​​another station area, the original collection scheme cannot solve the problem of low meter reading collection rate at this time; for example, when two interleaved communities Each uses its own meter reading system, but due to a series of reasons such as the remote location of the collector, the blockage of buildings, and signal interference, the system in its own community may not be able to collect, but the system in another community intersected with itself However, it can be collected, and a collaborative system is needed to solve this problem
