The invention relates to a meter reading system, particularly relating to a low-voltage resident centralized meter reading management system comprising four parts of an electric energy meter, a collector, a concentrator and a meter reading calculator; the concrete standard requirements of each part are as follows: an electric energy data transmission channel requires that a user electric energy meter needs to adopt a single-phase or three-phase four-line electronic type electric energy meter with a RS485 interface as required; a user check electric energy meter needs to adopt a three-phase four-line electronic type electric energy meter with the RS485 interface as required; each electric energy meter 485 transmission convention is required to satisfy the published 645 convention and the supplemented convention provided by our company; the requirements of a collector data transmission channel are as follows: the communication between the collector uplink and the concentrator needs to adopt a low-voltage electronic line as a data transmission channel; the communication between the collector downlink and the electric energy meter needs to adopt a RS485 line as the data transmission channel. The low-voltage resident centralized meter reading management system of the invention overcomes the above defects, thus having the following advantages of high meter reading efficiency, strong system operation reliability, strong anti-interference ability and accurate zero data storage and the like.
