摘要
A tunnel water inrush advance prediction device using nuclear magnetic resonance difference. A computer (1) connects to a transmission bridge circuit (5) through a high voltage power supply (4), to a main control unit (2) through a serial bus (15), to a first signal conditioning circuit (6) through a serial bus (16), to a second signal conditioning circuit (10) through a serial bus (18), and to a multi-channel collection circuit (7) through a serial bus (17); the main control unit (2) connects to a transmission drive circuit (3) through a control line (19), separately to a first protection switch (8) and a second protection switch (11) through a control line (20), and connects to the transmission bridge circuit (5) through the transmission drive circuit (3); two ends of a transmission and reception integrated multi-turn coil (12) connect to the multi-channel collection circuit (7) through the first protection switch (8) and the first signal conditioning circuit (6); two ends of a reception multi-turn coil (13) connects to the multi-channel collection circuit (7) through the second protection switch (11) and the second signal conditioning circuit (10); one end of the transmission and reception integrated multi-turn coil (12) connects to the transmission bridge circuit (5), and the other end connects to the transmission bridge circuit (5) through a harmonic capacitor (9). A tunnel water inrush advance prediction method using nuclear magnetic resonance difference. The device precisely determines the location, size, water content, and infiltration index of water bodies.
