Low voltage resident centralized meter reading management system

Abstract

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.

Description

technical field [0001] The invention relates to a meter reading system, in particular to a centralized reading management system for low-voltage residents. Background technique [0002] At present, the data collection work of electric meters is still completed by the traditional method of door-to-door door-to-door entry by over-standard personnel, which has many disadvantages. First, a large amount of manpower needs to be invested in meter reading work. The meter also reduces the safety of users. At the same time, there are also some inaccuracies in manual meter reading, which leads to corruption and bribery loopholes. With people's understanding of these disadvantages, some automatic overmeter systems have appeared, such as the automatic card-swiping type of the watt-hour meter. However, the above-mentioned method needs to be replaced with a new meter, and this card-swiping type of watt-hour meter is usually expensive.

[0002] At present, the data collection work of electric meters is still completed by the traditional method of door-to-door door-to-door entry by over-standard personnel, which has many disadvantages. First, a large amount of manpower needs to be invested in meter reading work. meter, which also reduces the safety of users. At the same time, there are also some inaccuracies in manual meter reading, which leads to loopholes in corruption and bribery

With people's understanding of these disadvantages, some automatic overmeter systems have appeared, such as the automatic card-swiping type of the watt-hour meter. However, the above-mentioned method needs to be replaced with a new meter, and this card-swiping type of watt-hour meter is usually expensive. For some older communities, or cities with relatively backward development levels, it cannot be effectively popularized

At the same time, with the increasing demand for electric energy and the rational use of electric energy in our country, there have been different pricing methods for high and low peak values, and neither the old-fashioned mechanical energy meter nor the electronic energy meter can be accurately measured.
