PURPOSE: A management system for buried materials is provided to prevent damage under construction and to help a construction plan by getting information for buried materials in advance. CONSTITUTION: The management system for buried materials comprises: probing equipment(10) containing a power supply unit(11) supplying power sources by converting an alternating current and a direct current into an alternating current, an induced magnetic field generating unit(12) generating a magnetic field by taking the power sources from the power supply unit(11), a guide magnetic field controlling unit(14) attached to the front end of the guide magnetic field generating unit and an antenna(17) receiving signals transmitted from the outside, a signal amplifying unit(18) amplifying the received signals, an analog/digital converting unit(19) converting the amplified signals into digital signals, and a data processing unit(13) processing the digital signals to be movable; a buried chip module(20) containing a guide magnetic field receiving unit(21) generating an alternating voltage from the magnetic field generated from the guide magnetic field generating unit, a circuit protective switching unit(22) switching if the alternating voltage is higher than the appointed value, an alternating current/direct current converting unit(23) converting the alternating voltage into a direct voltage, a microprocessor(24) controlling a buried chip module(20) by taking the appointed direct voltage, a memory(25) outputting the information of the buried materials stored by the control of the microprocessor(24), and a transmitting unit(26) transmitting the outputted information from the memory.
