An accounting device is connected to the pulse output 10 of the recorder counter. Substation 11, for example, a transformer substation (Fig. 2), is connected with consumers of electricity 12, for example, residential buildings, garages, etc.

Intelligent energy metering system works as follows. In FIG. 1 shows the operation of the pulse counter-recorder "Pulse PLC" in the "Counter" mode. A voltage of 220 V is supplied to the power supply unit 1, it, in turn, supplies all the elements in the memory of the controller 4. A metering device is connected, the pulses from which are supplied to the microcontroller 4 and stored in memory module 3, for example, “EEPROM”. For detailed adjustment and viewing of readings using software, interface 2 is used, for example, “RS485”. The pulse counter-recorder "Pulse PLC" in the "Concentrator" mode is connected to one of the phases and a request is sent through matching module 7 to the pulse counter-recorders in the "Counter" mode located in the same phase. The signal reaches the matching module 7 in the pulse recorder "Pulse PLC", passes through the bandpass filter 6, filter out the excess frequencies, amplifies it in the input amplifier 5 and gets into the microcontroller 4. Using the microcontroller 4, they receive the signal, go to the memory module "EPROM" 3 and send the actual data back, through the output amplifier 9, the high-pass filter 8 and the matching module 7. The pulse counter-recorder "Pulse PLC" in the "Concentrator" mode uses the "PLC interface" to collect readings from pulse counters-recorder in a "counter" mode «Pulse PLC».

In each involved channel, it is necessary to install one pulse counter-recorder “Pulse PLC” in the “Hub” mode. In each pulse counter-recorder "Pulse PLC" in the "Concentrator" mode, the data from the pulse counter-recorders "Pulse PLC" in the "Counter" mode installed in the same channel (phase) as the pulse counter-recorder "are recorded in the form of a table Pulse PLC ”in the“ Hub ”mode. Based on the recorded data, the Pulse PLC pulse counter-recorder in the Hub mode automatically polls the Pulse PLC pulse counter-recorders in the Counter mode using the PLC interface. In the process of polling via the PLC interface, the readings read from the pulse counters-recorders “Pulse PLC” in the “Counter” mode are recorded in the table of the pulse counter-recorder “Pulse PLC” in the “Concentrator” mode. The readings stored in the memory of the pulse counter-recorder “Pulse PLC” in the “Concentrator” mode are read by the interface, for example, 2 EIA485 (RS-485) manually or automatically using software. If there is a signal with interference between the pulse counter-recorder "Pulse PLC" in the "Counter" mode and the pulse counter-recorder "Pulse PLC" in the "Concentrator" mode, the relay mode in the intermediate pulse counter-recorder "Pulse PLC" is set via the software.
