DEVICE FOR LUMINOUS TRACKING OF OBJECTS ON PERFORMANCE STAGES Russian patent published in 1997 - IPC

FIELD: equipment for performance stages. SUBSTANCE: device has floodlight and elevation electric drive mechanically coupled with it, azimuth electric drive, and focusing electric drive, transmitter placed on moving object; elevation antenna assembly, azimuth antenna assembly, and elevation sensor mounted on floodlight; dual-channel elevation receiving channel whose two inputs are connected to two outputs of elevation antenna assembly and dual-channel azimuth receiving channel whose two inputs are connected to two outputs of azimuth antenna system, computer provided with external input for entering setting parameters, four inputs connected to two outputs of dual-channel elevation receiving channel and to two outputs of dual-channel azimuth receiving channel, input connected to elevation sensor, and three outputs connected to three inputs of three-channel control signal shaper; three-channel electronic relay provided with control input, three pairs of inputs connected to three outputs of three-channel control signal shaper and to three outputs of manual control console, and three outputs connected to inputs of azimuth, elevation, and focusing drives. EFFECT: improved accuracy of luminous tracking of objects moving on performance stage due to automatic control of floodlight beam. 2 dwg
