Abstract
Description
technical field
[0001] The invention relates to an electronic fee-controlled electric energy meter, in particular to a wireless centralized copy remote transmission fee-controlled electric energy meter. Background technique
[0002] The electronic energy meter reading methods commonly used now mainly include meter reading methods such as 485 communication, infrared communication, and carrier communication. These meter reading methods greatly shorten the time-consuming manual meter reading, but are limited by meter reading equipment and Table environment, low work efficiency.
[0003] Although the traditional meter reading mode has been widely recognized and vigorously promoted by the society, the work efficiency is low and difficult to achieve in special environments. For example, in the vast rural areas, electric energy meters are installed in meter boxes high It is almost impossible to install cumbersome communication lines for RS485 meter reading, and it is impossible to...
