Title: ELECTROMAGNETIC METHOD PROSPECTED PRIMARY FIELD LOOSE COUPLING RECEIVING DEVICE AND METHOD
Abstract:
An electromagnetic method prospected primary field loose coupling receiving device and method. The device comprises: a transmitter (1), a transmit coil (2), a signal conditioning module (4), and a receiver (5). Two transmit output ends of the transmitter (1) are connected to both ends of the transmit coil (2). The device further comprises n receive coils. The n receive coils constitute a receive coil module (3). The receive coil module (3) is connected to the signal conditioning module (4). The output end group of the signal conditioning module (4) is connected to the receiver (5). The receive coil module (3) is disposed at an edge of the transmit coil (2). The receive coil module (3) partially intersects the transmit coil (2). Part of the orthographic projection of the transmit coil (2) overlaps part of the orthographic projection of the receive coil module (3). Aliasing of a primary field and second field of a conventional receive coil is eliminated; the dynamic range of a receive signal is reduced, and the problem of being difficult to receive a signals of a weak second field is resolved; the application range is wide; an integrated system and convenient use are achieved; easy operation and accurate and reliable conditioning effect are achieved.
