The acquisition control board (1) outputs the control bit to the relay switching board according to the switch state to switch the required main and auxiliary transformer winding output combination, thereby opening a communication channel between the ground DITS communication board (114) and the downhole instrument; The DITS communication board (14) cooperates with the rotary switch (4), the coupling board (5), the relay board (11) and the analog acquisition unit (6) to form a DITS instrument signal processing and control unit, which is managed by the PC (104) mainboard (9) and communicates with each other through the CAN bus; the analog acquisition unit (6) collects power supply parameters, and the PC (104) mainboard (9) outputs control instructions to the programmable power supply through the serial port board (8) based on the power supply parameters. The DITS communication (14) communicates data with the downhole instrument. The analog acquisition unit (6) samples the SP natural potential analog signal and the CCL analog signal, completes the high-speed remote communication function with the DITS series instruments, and completes the acquisition of analog signals and the monitoring of voltage and current signals.

10. The ground integrated acquisition method compatible with multiple logging instruments according to claim 7, It is characterized in that When the logging instrument is an INSITE series instrument, the rotary switch (4) is turned to the INSITE gear position, and the state information of the rotary switch (4) is recognized by the acquisition control board (1). The acquisition control board (1) outputs a control bit to the relay board (11) according to the switch state to switch the required main and auxiliary transformer winding output combination, thereby opening a channel for power supply and communication between the ground INSITE communication board (13) and the downhole instrument. The INSITE communication board (13) and the coupling board (5), the relay board (11) and the analog acquisition unit (6) constitute an INSITE instrument signal processing and control unit, which is managed by a PC (104) mainboard and communicates with each other through a CAN bus to complete a high-speed telemetry communication function with the INSITE series instrument, and complete the acquisition of analog signals and the monitoring of voltage and current signals.
