SEISMIC VIBRATOR Russian patent published in 2003 - IPC

Abstract RU 2204846 C1

FIELD: seismic signal source. SUBSTANCE: newly introduced in seismic vibrator are hydraulic-cylinder vibration acceleration sensor and PID controller whose input is connected to output of vibration acceleration sensor and output, to one of inputs of control channel; PID controller incorporates provision for controlling operating frequency code. Seismic vibrator has remote-triggering channel, digital control signal generator, control channel, feedback channels, electrohydraulic converter, supporting slab vibration sensor, hydraulic cylinder casing, rod, supporting slab, vibration acceleration sensor, and PID controller. EFFECT: enhanced seismic efficiency due to high precision of follow-up of control signal with desired characteristics. 1 cl, 1 dwg
