Communication converter for resident electric energy centralized meter reading system

Abstract

The invention discloses a communication converter for a resident electric energy centralized meter reading system. The communication converter comprises a pass-through unit, a conversion unit and a router unit; the pass-through unit is connected with the conversion unit, and further used for being connected with a router of an electric transformer district concentrator of the resident electric energy centralized meter reading system; the conversion unit is connected with the router unit; the route unit is further used for being connected with nodes of the resident electric energy centralized meter reading system. The communication converter is not designed for specific manufacturers, and is easy to achieve and suitable for all conditions under which node networking needs to be compatible with; if there are more than two schemes on the site, the number of converters can also be increased according to the condition, and thus the problem is solved that spare meters and electricity metersin an electric transformer district are incompatible with each other in communication on the condition that the collecting scheme of the original electric transformer district is unchanged; there is no need to reserve many communication modules anymore, the communication converter is particularly suitable for modification of former electric transformer districts, so that in one electric transformer district, different meter reading modes run simultaneously without mutual interference, and the instability problem of meter reading through a carrier wave or micropower wireless technology is solved; moreover, on-site construction installation is convenient, and the operation is simple.

Description

technical field [0001] This application relates to the technical field of communication in the residential electric energy centralized copying system, in particular to a communication converter used in the residential electric energy centralized copying system. Background technique [0002] Residential electricity consumption information collection system is a system that collects the readings of scattered residents' meters through various communication means, and finally uploads them to the marketing system for electricity bill settlement. The power consumption information collection system is mainly composed of the main station of the management system, concentrators, carrier energy meters / collectors, etc. Taking broadband carrier communication as an example, multiple broadband power line carrier signals are uploaded to the concentrator through the collector, and then transmitted remotely To the master station of the management system, where the energy meters include singl...

AI Technical Summary

Problems solved by technology

However, due to some technical reasons, it also brings some troubles to the meter reading work.

The main problem is that there are various communication solutions between the concentrator and the meter, mainly including: micro-power wireless, narrowband carrier, G3 carrier, broadband carrier, etc. The communication technology solutions of each communication module manufacturer are basically independent research and development, there is no unified This has resulted in the incompatibility of communication between various communication schemes. The spare meter is incompatible with the communication of the electric meter in the station area, and a variety of communication modules need to be spared, and the problem of the old station area transformation is particularly serious. For the operation and maintenance of the station area management caused great difficulty
