INTEGRATED MANAGEMENT AND CONTROL SYSTEM OF PARAMETERS AND OPERATING MODES OF MACHINES AND EQUIPMENT FARM PRODUCTION MACHINE Russian patent published in 2018 - IPC A01J5/07 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular, to equipment for milking and milk collection. Sensors (1) to (6) are connected to multi-channel digital meters (7) to (12), whose outputs are connected via data acquisition module (13) to the computer (14) of the truss. Video cameras (15) through visual control recorder (16) are connected to farm computer. Farm computer along the line (17) is connected to users' computers (18). Farm computer is made in form of a series-connected master oscillator, phase manipulator, the second input of which is connected via modulating code generator to outputs of data acquisition module and visual inspection recorder, power amplifier and transmit antenna (22.1). User's computer is made in form of series-connected receiving antenna (23), high-frequency amplifier, mixer, the second input of which is connected to the first output of local oscillator, the first low-pass filter, multiplier second input of which is connected to high-frequency amplifier output, narrowband filter, phase detector whose second input is connected to the second output of local oscillator and second low-pass filter whose output is connected to control input of local oscillator. First low-pass filter output is connected to registration unit input.

EFFECT: noise immunity of receiving complex signals with phase shifting and reliability of its demodulation increase.
