THE PRINCIPLE OF AUTOMATIC METER READING OF ELECTRIC ENERGY METER

Author: admin / 2022-07-25

Energy Meter Detection Bench is one of our products. Let us understand the principle of automatic meter reading of electric energy meters.

  The data read from each electric energy meter is first centralized, and then transmitted to the electric energy meter management center, and then managed in a unified manner. Our commonly used transmission methods are:

  1. Use the power line to implement the carrier communication to transmit the data.

  2. Use the telephone network for data transmission.

  3. Use wireless means to transmit data.

  4. Use optical fiber to transmit data.

  It can be seen in the picture below that it is a complete automatic meter reading system. The data collector reads out the data of the connected meter, and the station concentrator communicates with all the data collectors within the power supply range of the same transformer to collect and store the data of all the meters in the station. The communication method can be RS485 or power line carrier. Way. Then you can wake up the concentrators in each station area in turn to transmit data through the modulation and interpretation device (MODEM), wirelessly, or using the car radio. Of course, you can also directly use the handheld computer to communicate with the collector and the concentrator to collect data and transmit it to the power management center. Below we will explain in detail the principle of the transmission method.
