Document Type and Number:
Japanese Patent JP3211179
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a ground displacement measuring system suitable for removing the noise components and capable of reducing the power consumption.
SOLUTION: In a signal transmitting section 10, power is fed to each part thereof at a time preset by a timer circuit 14 and a detection signal of clinometer 11 in the form of a magnetic signal is transmitted from the bottom of the water. At a signal receiving section 20, the magnetic signal received by a receiving coil 21 is converted through a conversion circuit 23 and recorded on a recorder 24. The content of record is then collected and reproduced before being demodulated to produce the detection signal from the clinometer 11.
