FIELD: measurement equipment. ^ SUBSTANCE: optoelectronic metering system, comprising source and receiver of optical radiation, device for information decoding and display, fibre light guide with fibre splitter of Y-type at one end, photovoltaic diode, integrator, device for information reception and coding. Inlet of fibre splitter is optically joined to source, and outlet - to receiver of optical radiation, the second end of fibre light guide is optically joined to photovoltaic diode, which is connected to integrator. Outlet of optical radiation receiver is connected to the field of information decoding and display. System comprises modulator joined to source of optical radiation, electronic two-position switch, voltage converter, comparator and controlled source of voltage. Photovoltaic diode is arranged on the basis of material, having electroluminescent properties, besides anode of this diode is connected to inlet of integrator and common contact of two-position switch joined in one position to inlet of voltage converter, and in another position - to outlet of information reception and coding device. Outlet of comparator is connected to control inlets of electronic two-position switch and device of information reception and coding, one inlet of comparator is connected to outlet of integrator, and another one - to outlet of controlled source of voltage. ^ EFFECT: improved efficiency of metering system functioning, which consists in improved accuracy of metering system. ^ 2 dwg |
