DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a position-maintaining type oceanographic observation apparatus used for oceanographic observations such as oceanographic observations and oceanographic weather observations.

[0002]

2. Description of the Related Art Conventionally, there are two types of sea condition observation devices used for sea condition observation, such as ocean observation and ocean weather observation, of a mooring type and a drift type.

[0003]

However, since it is difficult to moor the oceanographic observation device in the deep sea area, the deep sea area relies on observation from a drifting buoy or an artificial satellite. In the case of artificial satellites, buoys are swept away by tidal currents and the like, and observation positions shift due to the rotation of the earth, so that long-term data collection in a predetermined sea area cannot be performed. Therefore,
At present, sufficient observation data cannot be obtained in the deep sea area.

SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem. It is an object of the present invention to facilitate installation in a predetermined sea area and enable long-term observation in the predetermined sea area. It is an object of the present invention to provide a position-maintaining type oceanographic observation device.

[0005]

According to the present invention, there is provided a position-maintaining type oceanographic observation apparatus, which can achieve the above object, by mooring a buoy equipped with an observation apparatus and a submerged buoy-holding boat capable of transmitting and transmitting signals. A control device for controlling the controller by connecting to the submersible buoy holding boat with a positioning device, comparing a self-position measured by the positioning device with a fixed point input in advance, and a command of the control device. And a controller for returning the submerged buoy holding boat to the observation sea area centered on the fixed point.

[0006] When a buoy and a submerged buoy holding boat connected by mooring lines capable of power transmission and signal transmission are thrown in the vicinity of the observation sea area, a control device mounted on the submerged buoy holding boat inputs in advance a signal. Controlling the controller of the submersible buoy holding boat by comparing a fixed point with the self-position measured by the positioning device, tow the buoy connected by mooring lines into the observation area around the fixed point, and observe Do.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, A is a position-maintaining marine observation apparatus, and the position-maintaining marine observation apparatus A connects a buoy 10, a submerged buoy holding boat 20, a buoy 10 and a submerged buoy holding boat 20. A mooring line 30 is provided.

The buoy 10 includes an observation device 11 for observing weather and the ocean, a transmission antenna 12, and a reception antenna 13.
And a relay 14. On the other hand, the submersible buoy holding boat 20 includes a sonar 21, a positioning device 22, and a positioning device 2.
The control device 23 controls the controller 24 by comparing the self-position measured by the control device 2 with a fixed point input in advance, and the rudder 2 provided on the submersible buoy holding boat 20 according to a command from the control device 23.
5 and a controller 24 for controlling the propulsion motor 26 and a ballast 27.

In FIG. 1, reference numeral 40 denotes an artificial satellite, 5
0 is a transponder installed on the sea floor 60. Now,
When the buoy 10 and the submerged buoy holding boat 20 connected by the mooring cable 30 are thrown in the vicinity of the observation sea area W of a fixed radius centered on the fixed point, the control device 23 mounted on the submerged buoy holding boat 20 The fixed point previously input into the control device 23 is compared with the self-position measured by the positioning device 22 based on the signal of the artificial satellite 40, and the controller 2 of the submersible buoy holding boat 20 is compared.
4 is controlled. Next, the controller 24 controls the rudder 25 and the propulsion motor 26 provided on the submerged buoy holding boat 20, and the buoy 10 connected via the mooring line 30 has a constant radius around the fixed point in the observation sea area. Tow and conduct oceanographic and meteorological observations. This observation data is transmitted from the transmitting antenna 12 directly or via the artificial satellite 40 to a ground base (not shown).

On the other hand, when the buoy 10 deviates from the observation sea area due to an external force such as a tidal current or a wind wave, the buoy 10 is again returned by the above method. In the above description, the case where the signal from the artificial satellite 40 is used for the self-position measurement has been described. However, the signal of the transponder 50 installed on the sea floor 60 may be used.

The replacement and charging of the battery of the submersible buoy holding boat 20 are performed by floating the submersible buoy holding boat 20, while when the mooring line 3 is cut, the ballast 27 is separated and floated. , Sends an alarm signal to the land base.

[0012]

As described above, according to the present invention, a buoy equipped with an observation device and a submerged buoy holding boat are connected via a mooring line capable of transmitting power and transmitting signals, and a submerged buoy holding is provided. The boat, a positioning device, a control device that compares the self-position measured by the positioning device with a fixed point input in advance, and controls the controller, and a submerged buoy holding boat centered on the fixed point based on a command from the control device. Since it is equipped with a controller that returns to the observation sea area, the installation at the observation point is easy regardless of day and night as long as the sea conditions are met.

Further, the observation buoy can be automatically moved into an observation sea area within a certain radius centered on a fixed point by the submerged buoy holding boat, and long-term observation data can be obtained.
In addition, it is also possible to perform moving observation in which observation is performed while automatically moving between a plurality of preset fixed points by applying the function of the present apparatus.
