PROTOTYPE OF MONITORING SYSTEM WITH POWER SUPPLY VIA OPTICAL FIBER

Annotation

The capabilities of ready-made units of power supply via optical fiber (PoF platforms) of low power up to a few watts for the development of systems for collecting information coming from a carbon monoxide sensor are investigated. The operability of the system is demonstrated, its shortcomings are noted: low efficiency, complexity of modernization, lack of a system for adjusting the power of a laser diode with computer control through a microcontroller. A power supply system via medium-power optical fiber (tens of watts) is developed, on the basis of which a prototype system for monitoring remote sensors of physical quantities is created. The prototype is tested in various operating modes. Recommendations are given for the use of the number of power supply channels depending on the peak electrical power consumed by individual sensors and the system as a whole. Recommendations have been developed for optimizing operating modes in order to increase the efficiency and reliability of the system by reducing the operating temperature of the laser diode and photoelectric converters.
