METHOD OF ELEVATORS REMOTE CONTROL AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC B66B1/00 

FIELD: control systems.

SUBSTANCE: invention relates to the field of elevator installation devices for remote monitoring of elevators. Device implementing the method of remote monitoring includes a cabin moving sensor, converter unit, processing unit, time counter with real-time clock, a computing element, a comparison node, trip counter, analog code converter, delay line, adder, a pseudorandom sequence generator, modems, master oscillator, source of the analog message, amplitude modulator, phase manipulator, power amplifier, transmitting antenna, receiving antenna, high frequency amplifier, heterodyne, a blending machine, intermediate frequency amplifier, amplitude limiter, a synchronous detector, registration unit, a demodulator of complex signals with combined amplitude modulation and phase manipulation, multipliers, narrow-band filter and low-pass filter.

EFFECT: increase in the efficiency of remote monitoring of elevators by using complex signals with combined amplitude modulation and phase manipulation is achieved.
