A communication module antenna for receiving a communication signal of the wireless communication module,
A secondary battery that supplies power to operate the GPS module and the wireless communication module,
A solar cell panel that is powered by solar light to charge the secondary battery,
A connection terminal to which the connector of the connection cable is connected, and
And a disconnection preventing unit for disconnecting the connector from the connection terminal to prevent disconnection of the connection cable when an external force acts on the connection cable in accordance with the change of the position of the water supply and drainage pipe or the change of the position of the ground unit. Verification of pipeline buried location and real time management system. The method according to claim 1,
And a earth pressure blocking pipe connecting the buried unit to the ground unit and preventing the earth pressure from being applied to the connection cable when the connection cable is received. The method according to claim 1,
The break-
A first rotating wheel and a second rotating wheel in which a pair of the connecting cables are spaced apart from each other so as to engage with each other in a zigzag form,
A wheel connecting rod connecting the first rotating wheel and the second rotating wheel,
The first rotating wheel and the second rotating wheel are formed between the first rotating wheel and the second rotating wheel at the wheel connecting rod so that the first rotating wheel and the second rotating wheel rotate about the wheel connecting rod when the connecting cable is pulled by an external force Rotation axis,
A support spring for supporting the wheel connecting rod by an elastic force so that the connecting cable is supported on the first rotating wheel and the second rotating wheel in a zigzag form,
And a separation lever installed at a portion adjacent to the wheel connecting rod and separated by the rotation of the wheel connecting rod to separate the connector from the connecting terminal. 3. The method of claim 2,
And a connector interlocking part installed at an end of the earth pressure shut-off pipe at which the ground unit is installed, for preventing the connector separated from the connection terminal from being inserted, thereby preventing the connector from being inserted into the earth pressure shut-off pipe. Verification of pipeline buried location and real time management system.
