Problems solved by technology
In this way, firstly, each concentrator is connected to the master station through GPRS, which increases the GPRS traffic cost and the GPRS network burden. Secondly, the master station needs to integrate and process the data of each associated concentrator to obtain the total data, which increases the processing complexity of the master station

Embodiment Construction
[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0032] As shown in Figure 1, a meter reading system based on a concentrator network includes:
[0033] More than one electric energy meter group 1 composed of more than one electric energy meter 11, slave concentrator 2, main concentrator 3 and master station 4 with the same number of electric energy meter groups.
[0034] A carrier communication module is embedded in the energy meter 11 for communicating with the slave concentrator 2 . The energy meter 11 is used to collect user electricity, measure electricity, measure demand and record events, and supports time-of-use metering, and communicates with a slave concentrator with an infrared communication interface through a power carrier.
[0035] The slave concentrator 2 is composed of a slave carrier communication module and a slave central processor connected to the slave carrier c...

The invention discloses a concentrator-network-based meter reading system and a concentrator-network-based meter reading method. The meter reading system comprises a master station, a master concentrator, a slave concentrator and an electric energy meter. The meter reading method comprises the following steps of: reading data in the electric energy meter from the concentrators; reading data in the slave concentrator by the master concentrator, and adding the data; and uploading the added data to the master station. By the system and the method, a plurality of concentrators can share one subscriber identity module (SIM) card, so general packet radio service (GPRS) network resources and GPRS flow are saved, the data in all concentrators is not needed to be integrated and processed by the master station, and the processing program of the master station is simplified.
Description
technical field [0001] The invention relates to a meter reading system and a meter reading method. Background technique [0002] In the power system, when collecting electric energy for a large user, the user may have multiple meters and install them in different areas. The previous method is mainly to install multiple concentrators according to the actual situation. The record data is reported to the master station, and the master station then summarizes and calculates these record data according to the existing user files. For example, a kind of intelligent meter reading system is disclosed in the patent document whose application date is 2007.2.1 and the publication date is 2008.8.6 in the patent No. ZL200710037071.9, which specifically discloses that it includes several electric meters and a concentrator connected with several electric meters. , and the system master station wirelessly connected to the concentrator, including: electricity meter, used to collect user ele...
