Formation tester ground control system

The invention discloses a formation tester ground control system. The system is connected with an underground instrument through a logging cable and comprises a control panel used for carrying out underground instrument data collection and cable depth and tension signal collection, a high-voltage direct-current power supply used for achieving direct-current power supply for the underground instrument, a high-voltage alternating-current power supply used for achieving alternating current power supply for the underground instrument, and a signal processing module used for carrying out postprocessing on the underground instrument data and the cable depth and tension signals collected by the control panel. By means of the formation tester ground control system, the interface compatibility performance of the ground system can be improved, and the portable performance can also be improved.
