System for monitoring airport equipments utilizing power-line carrier

摘要

A power-line carrier airport facilities monitor system, comprising a host station and respective terminal for monitoring individually the object facilities via a rubber transformer are connected in series to a power line derived from a fixed current generator, wherein the host station and respective terminal create a control command for respective terminal/monitoring signal of the object facilities as text data and, on the other hand, injections said text data to the power line by FSK modulation based on the zero cross detection of the power line power source waveform.
