What's the use of a collector on the meter?

Nowadays, most of the residential meters are smart meters. In addition to the functions of metering and cost control, they can also communicate upward and access to the power consumption information collection system. If the system operates normally, it can see all kinds of electricity data before the day of the meter. In many places, the intelligent meter generally does not need to read meters manually, and the purpose of reading meters can be achieved through the system.

In order to be able to upload this system, the intelligent single meter communicates with the upper layer in 485 or carrier, micro power wireless and other ways according to different types, and transmits information layer by layer, finally reaching the power consumption information collection system.

You said that this kind of intelligent meter should use the 485 port in the weak terminal, gather the 485 port of multiple meters into a collector, multiple collectors use the carrier or micro power mode to connect to a concentrator, the concentrator uploads the mobile or Unicom signal to the power consumption information collection system of the power company, to achieve the purpose of power consumption information collection.

The collector is not a necessary device in the whole system, because some meters can be directly uploaded to the concentrator by carrier or micro power wireless way, which is related to the degree of dispersion of meter users and communication conditions.
