Abstract

The invention provides a power line carrier-wave communication based remote meter reading device. An acquirer is used for acquiring data of an intelligent electric energy meter; a meter reading serveris used for reading the data acquired by the acquirer, and sending a meter reading instruction to the acquirer; and the acquirer communicates with the meter reading server through a secondary carrier-wave machine, a secondary coupler, a power line, a main coupler and a main carrier-wave machine in sequence. According to the scheme, communication between the meter reading server and the acquirer can be realized through the power line, and a communication network does not need to be independently erected while the remote meter reading function is realized, so that cost of remote meter reading is greatly reduced. A temperature sensor and a humidity sensor are arranged, so that the acquirer can acquire a working environment when the intelligent electric energy meter works, and therefore, theworking environment of the intelligent electric energy meter and related power distribution devices can be effectively monitored, maintenance of a power grid is facilitated, and stable performance inan operation process of the power grid is improved.

Description

technical field [0001] The invention relates to accessories for power grids, in particular to a remote meter reading device based on power line carrier communication. Background technique [0002] As the coverage area of ​​the grid increases, the maintenance of the grid becomes more and more difficult. For example, it is a very complicated job to read the electric energy meter connected to the power grid. Especially the meter reading personnel who have just entered the job may not know the actual location of the electric energy meter. Therefore, the meter reading personnel need to find someone to lead the way when reading the meter. [0003] In the prior art, the meter reading of the electric energy meter is generally done manually by the operator. On the one hand, this method of meter reading increases the labor intensity of the operator. Or other mistakes are easy to copy wrong data. For the various defects of manual meter reading, a smart electric energy meter has appea...
