Automated system for registration and control of electric energy has central processor with bus of serial interface, N channels of count of disc revolutions by number of controlled electric energy meters, inputs of channels are connected to information inputs of central processor. Each channel has block for pulse formation and detector of revolutions of disc, pulse forming block includes bridge rectification circuit, pulse generator of optical modulator, pulse transmitter, pulse receiver, monostable univibrator, output amplifier, disc of electric meter and two-wire power supply bus. Detector od revolutions of disc consists of pulse former, pulse transformer and pulse counter. |
