Abstract

The invention relates to an intelligent meter 485 port voltage stabilizing device and a work method thereof. The device comprises a first voltage stabilizing module, a first 485 signal conversion chip, a second 485 signal conversion chip and a second voltage stabilizing module which are sequentially connected. The intelligent meter 485 port voltage stabilizing device can effectively solve the problem that the voltage of an intelligent meter 485 port is unstable, maintenance content is reduced, work efficiency of field debugging and maintenance staff is improved, operation cost of power supply enterprises is reduced, and the device is simple, practical and convenient to install.

Description

[0001] Technical field: [0002] The invention relates to a 485 port voltage stabilizing device of a smart meter and a working method thereof, belonging to the technical field of smart meter communication and control. [0003] Background technique: [0004] Smart meters have developed rapidly in recent years, but due to the huge production quantity, the share of problematic meters is relatively high, the voltage of port 485 fluctuates greatly, and the voltage level is different, which leads to the installation of smart meters separately and the mixing of different types of meters. Data cannot be collected normally during installation. At present, smart meters are mainly used to increase the effectiveness of data collection by adding collection equipment, but this method not only increases production costs, reduces company benefits, causes waste of resources, but also causes data to be unable to be collected normally, directly affecting power supply The enterprise monitors the ...
