Electromagnetic wave CT data acquisition system

Abstract

The embodiment of the invention provides an electromagnetic wave CT data acquisition system. The electromagnetic wave CT data acquisition system comprises a winding and unwinding device, a cable, a probe, a positioning pulley, a visual detection device and a control module. The winding and unwinding device comprises a stranded wire disc and a motor, a rotating shaft of the motor is coaxially connected with a rotating shaft of the stranded wire disc, the motor rotates to drive the stranded wire disc rotate, and the motor is connected with the control module. One end of that cable is connected with the probe, the other end of the cable is connected with the stranded wire disc and wound at a preset position of the stranded wire disc, the cable enters a transmitting channel or a receiving channel after passing through the positioning pulley, and a depth mark is arranged on the outer surface of the cable. A vision inspection system comprises a camera, wherein a camera lens of the camera faces the outer surface of the cable between the stranded wire disc and the positioning pulley, and the camera is connected with the control module. The control module controls the winding and unwindingdevice to realize automatic wire winding and unwinding so as to avoid heavy workload of manual operation and instability of manual operation. The depth value is fed back by the visual inspection device to realize the accurate control of the probe depth.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of geological exploration, and more specifically, to an electromagnetic wave CT data acquisition system. Background technique [0002] Karst detection usually adopts electromagnetic wave CT method. The instruments and equipment used in this method include a main engine, a twisted reel, pulleys, probes and cables. During the field test, the probe and the cable are put into the hole through the pulley, and one end of the connecting line is connected to the host. The cable twisting reel is used for retracting and unwinding the connecting wires. [0003] At present, the twisting reel is manually operated, and there is a large error in the placement depth of the probe; the twisting is uneven, resulting in fast and slow speed when paying off the wire, which affects the safety of the probe; The degree of coordination is high, and once a deviation occurs, it is difficult to find it in time, ...

AI Technical Summary

Problems solved by technology

[0003] At present, the twisting reel is manually operated, and there is a large error in the placement depth of the probe; the uneven twisting causes the speed of the wire to be unwound from time to time, which affects the safety of the probe; The degree of coordination is high. Once a deviation occurs, it is difficult to find it in time, which has a great impact on the collection efficiency. Problems are more likely to occur when the project volume is too large
