Title:
DUAL-COIL COUPLED MULTI-WAVE EXPLORATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/126724
Kind Code:
A1
Abstract:
A dual-coil coupled multi-wave exploration system, comprising a transmission control system. A first set of pulse signal output ends of the transmission control system is connected with a master transmitting coil, and a second set of pulse signal output ends of the transmission control system is connected with a slave transmitting coil. The master transmitting coil and the slave transmitting coil are coupled coils and are overlapped in position. A receiving coil module is provided at the edge of the master transmitting coil, and is partially intersected with the master transmitting coil; and the partial orthographic projection of the master transmitting coil is coincide with the partial orthographic projection of the receiving coil module. The dual-coil coupled multi-wave exploration system can realize alternate detection of the deep part and the shallow part, is short in the current turn-off time for the shallow detection, low in loss, high in detection precision and work efficiency, simple in structure and high in mobility; the master transmitting coil and the receiving coil module are intersected partially and thus the mutual inductance influences between the master transmitting coil and the receiving coil are cancelled, so that the exploration precision is improved.
