MULTI-SENSOR FIBER-OPTIC DATA ACQUISITION DEVICE Russian patent published in 2021 - IPC G02F7/00 H03M1/12 

FIELD: automation and computer technology.

SUBSTANCE: invention relates to automation and computer technology and can be used in control systems of complex technological equipment, as well as in monitoring spatially distributed objects of industrial, transport and social infrastructure. The claimed multi-sensor fiber-optic information acquisition device contains a radiation source, a fiber-optic splitter, a set of optical switches, a set of optical attenuators, a fiber-optic adder, a photodetector, a photo amplifier, and the output of the radiation source is optically connected to the input of the fiber-optic splitter, the outputs of which are connected through optical switches to the inputs of the corresponding optical attenuators, the outputs of which are optically connected to the inputs of the fiber-optic adder, the output of which is connected to the input of the photo amplifier via a photodetector. At the same time, a microcontroller with a built-in two-position analog key and an analog-to-digital converter are additionally introduced into it, the inputs of the analog key are connected in parallel to the output of the photo amplifier, the output of the analog key is connected to the input of the analog-to-digital converter.

EFFECT: increase in the reliability of the conversion of the information acquisition device due to the microprocessor correction of the dynamic error of the conversion.
