The present invention relates to a marine facility monitoring system and method, and more particularly to a marine facility monitoring system and method for monitoring the condition of the marine facility using radio waves.

In general, marine facilities installed at sea are affected by waves and tidal currents, so there is a risk of loss or damage due to climate change. Nevertheless, in order to know whether these offshore facilities are lost or damaged, it is inconvenient for a manager to directly check the offshore facilities and check them visually.

In particular, the cage device is located on the surface of the water and is affected by a wave or tide, and when there is a strong wind or typhoon, there is a high possibility that the cage device is lost or damaged. However, since it is very difficult to install such a cage device to withstand severe waves or tides, considering the technical level and cost, it is very important to detect such loss or damage quickly and to recover it early.

The technical problem to be achieved by the present invention is to provide a marine facility monitoring system and method that allows the administrator to easily and quickly determine whether the marine facility is damaged or lost by monitoring the marine facilities, especially cage cages using satellites.

Marine facility monitoring system according to the present invention for achieving the above technical problem is a marine facility; A transceiver for generating location information on the marine facility using the received radio waves; And a monitoring device generating monitoring information on the state of the marine facility based on the generated location information.

According to an aspect of the present invention, there is provided a marine facility monitoring method comprising: generating location information of a transceiver using radio waves received by a transceiver installed in a marine facility; And generating monitoring information for the marine facility based on the generated location information.

As described above, according to the marine facility monitoring system and method according to the present invention, by using the satellite to monitor the location of the marine facility or the location of the transceiver installed in the farm, etc., the manager can quickly and easily damage or disappear of the marine facility or farm It has the effect of letting you know.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the configuration of a marine facility monitoring system according to an embodiment of the present invention. Referring to FIG. 1, the marine facility monitoring system according to the present embodiment includes a marine facility 100, GPS satellites 110, a transceiver 120, and a monitoring device 130.

The marine facility 100 is a facility installed on the sea to be monitored according to the present embodiment, and means any one of the facilities installed on the cage, a food supply device for feeding the fish and shellfish farmed in the cage, and other facilities installed on the sea. do. The marine facility 100 is provided with a transceiver 120 for receiving radio waves from the GPS satellites 110.

The GPS satellites 110 transmit a radio wave to the transceiver 120, each of which includes data about the position of the GPS satellite in orbit and the time at which the GPS satellite sent the radio wave.

The transceiver 120 is installed in the marine facility 100, receives radio waves from the GPS satellites 110, generates location information of the transceiver 120 using the received radio waves, and monitors the generated location information. Transmit to device 130. The transceiver 120 may be installed in the maritime facility 100 as many times as necessary to monitor the maritime facility 100.

An example in which the transceiver 120 generates location information of the transceiver 120 using radio waves received from four or five GPS satellites 110 will be described in detail. The satellites constituting the GPS satellites 110 at this time will be referred to as a first GPS satellite 111, a second GPS satellite 112, a third GPS satellite 113, and the like.

The transceiver 120 transmits the radio wave by using the position on the orbit of the first GPS satellite 111 included in the radio wave received from the first GPS satellite 111 and the time when the first GPS satellite 111 sent the radio wave. The position of the transmitted first GPS satellite 111 and the distance between the first GPS satellite 111 and the transceiver 120 are calculated. In the same way, the transceiver 120 may determine the location of the second GPS satellite 112 and the distance between the second GPS satellite 112 and the transceiver 120, the location of the third GPS satellite 113, and the third GPS satellite 113. ) And the distance between the transceiver 120.

In this case, the reference range refers to a range in which the transceiver 100 or the marine facility 100 in which the transceiver 120 is installed is to be located. For example, the reference range may be a range preset by the administrator. For example, the reference range may be a range set based on the received location information for several days to one month. And if the location information received as a result of the inspection does not meet the preset reference range, the monitoring device 130 generates an alarm or the like so that the administrator knows that the location of the marine facility 100 is significantly moved or lost.

In particular, the monitoring device 130 transmits a voice message or a text message indicating that the location of the marine facility 100 has been moved or lost by the manager's mobile phone, etc. so that the manager may know the situation regardless of the location. It may be.

In FIG. 1, the location information of marine facilities is collected using GPS satellites, but location information may be collected using the following method without using GPS satellites.

One method is an E-OTD in which two or more base stations send a radio wave to a transceiver, measure the time it takes for the radio wave to return from the transceiver, and collect location information of the marine facility 110 based on the measured time. (Enhanced Observed Time Difference) method may be used. In this case, the device that transmits and receives the radio wave to the transceiver is not limited to the base station, and may be a device capable of exchanging radio waves with the transceiver while being fixed at one point on the land or the sea floor.

Another method is to collect transceivers between two or more offshore installations by installing transceivers in two or more offshore installations, exchanging radio waves between the installed transceivers, and losing the offshore facility based on the collected mutual location.
