The measurement sensor module 120 performs measurement on a desired seawater layer while rising from the submerged mooring equipment 110 during measurement, , Measurement object information, measurement target observation items, measurement time, and measurement interval, based on the measurement control information, and generates measurement information for the seawater layer.

The communication module 130 transmits the measurement information of the seawater layer generated by the measurement sensor module 120 to an external device, and performs wireless communication with the remote site in a state of reaching the sea level. Here, the external device may include a server managed by a remote location, and a portable terminal (e.g., smart phone, PDA, etc.) carried by the administrator.

Also, the communication module 130 can be manufactured in a negative shape by applying a structure that is raised by buoyancy.

For example, the measurement sensor module 120 may be configured in addition to the communication module 130 at the lower portion of the buoy.

The ascending and descending module 140 reciprocally moves the sub-type communication module 130 and the measurement sensor module 120 between the inside of the submersible mooring equipment 100 and the sea surface, In the case of moving, the buoyant force is raised, and when moving from the sea surface to the inside of the underwater mooring equipment 100, the power can be used.

For example, the ascending / descending module 140 applies a winch structure, and a strand type wire rope (W) is wound up when the sub-type communication module 130 and the measurement sensor module 120 are lifted. When the sub-type communication module 130 and the measurement sensor module 120 are lowered, the drum to which the wire rope is wound is rotated.

In this case, a separate buoy generator (buoy) and an up / down module 140 are configured in the measurement sensor module 120, Do.

When the measurement sensor module 120 reaches the set water depth (step S103), the control module 150 can control the measurement sensor module 120 to measure the set measurement object (step S104). In this case, various sensors may be constructed including a depth sensor for checking the depth of water in the measurement sensor module 120. The control module 150 may control the sensor module 120 based on the information required for each seawater layer, Only a part of them can be operated.

When the transmission of the measurement information for each seawater layer is completed, the control module 150 can wait for a predetermined time on the sea surface (step S204).

At this time, when new measurement control information is received from an external device at a remote place via the sub-type communication module 130 (step S205), the control module 150 can update the previously stored measurement control information with the received measurement control information (Step S206).

If the measurement control information is updated as described above (step S206), and the new measurement control information is not received for a predetermined time (waiting time) (step S208), the control module 150 controls the measurement sensor module 120 and the sub- The communication module 130 can be moved to the inside of the submarine mooring equipment 110 (step S207).
