How does Smart Meter Realize Remote Meter Reading?

As a Din Rail Meter Manufacturer, share with you.

Measuring Devices Meter is different from traditional electric meters, IC card electric meters are that it can be networked and can read meters remotely. Remote meter reading is the most basic meaning of smart meters. As for how to realize remote meter reading, there are many smart meter implementation patterns.

The power carrier table used by Guodian, the largest amount, is connected to the collector through a wire, and the collector uploads the reading to the remote copy server through GPRS, so the residents of the State Grid can basically check the daily electricity consumption of their homes through palm power. Most manufacturers that provide this solution and products work directly with Guodian.

Secondly, the second largest quantity is the smart meters that are connected to the 485 bus in large buildings. The collector is connected to the collector through the 485 bus, and the collector is converted into a TCP / IP network cable to directly go to the remote copy server. There are many manufacturers that provide this system, such as Tuoqiang, which directly integrates with buildings.

The third is the current youth apartments, white-collar apartments, hotel apartments use more WIFI meters, this meter is directly connected to the WIFI remote copy server in the apartment, of course, there are GPRS meters, which are used in smart meters. Big case. This amount of usage can be directly purchased online to install the meter, and then can be used directly through the app.

The fourth is the future true IoT smart meter, NB-IoT meter, which is the premature product that Huawei and operators are currently promoting. The smart meter directly connects to the remote server through the NB-IoT network.

The meter reading system can correctly identify the value displayed on the electricity meter and correctly transmit the value back. It is a product of technological development. Now with the continuous development of the economy, people have more demands on all aspects of life. High, it uses fixed-point communication of the antenna. After the installation is completed according to the technical requirements, it can communicate for 24 hours without being affected by the fluctuation of the power grid. In addition, it is also very fast. Due to the high rate of meter reading, it is possible to perform meter reading and billing in divided periods, which is very convenient. Now this meter reading system is also called wireless meter reading system, centralized meter reading system, Automatic meter reading system.

This remote meter reading system can directly realize the remote automatic meter reading function in the central control room, and can also form a regional meter reading network centered on the central control room. Its advanced technical means can identify the reading of the electric meter through the electronic eye, and keep the strict electronic reading consistent with the reading of the meter head.
