A magnetic communication system having a receiving unit that is received by a ground station is disclosed. That is, the measuring rod includes a sensor for detecting ground data such as rotation speed during boring rotary excavation, excavation speed, bit thrust, rotation torque, water pressure and load, and a modulation circuit for amplifying and modulating the ground data signal from the sensor. And a magnetic signal conversion circuit for converting the modulated signal into a magnetic signal, and this magnetic signal was transmitted to the receiving unit of the ground station via the boring rod which is a magnetic material.

る。However, in the above-mentioned conventional technique, the ground data is transmitted as a strong magnetic signal to the receiving unit of the ground station via the boring rod which is a magnetic material. The magnetic field signal causes the boring rod itself to be magnetized. Therefore, the next magnetic field signal is transmitted via the magnetized boring rod, and there is a problem that accurate ground data cannot be transmitted repeatedly. Then, the technical subject of this invention is providing the ground data transmission apparatus which can transmit ground data correctly and repeatedly in view of the said fault.
