Description

  The present invention relates to an underwater mooring monitoring system for monitoring the state of underwater moorings such as floating fish reefs moored underwater or on the surface of water.

Floating fish reefs, which are underwater moorings, are a type of artificial reefs that are fixed to the seabed and are anchored to anchors by mooring lines and moored in a floating state in the surface layer or middle layer of the sea area. Known (see Patent Documents 1 and 2). Such floating fish reefs are intended for migratory fish and netted fish in the surface and middle layers of the sea area, and are effective in guiding and collecting fish schools.
However, such floating reefs, unlike subsidence type reefs that are submerged and fixed on the sea floor, may flow out due to mooring line cutting or the like.

Therefore, conventionally, a monitoring device has been proposed that issues an alarm or the like when underwater moorings such as floating fish reefs flow out.
For example, Japanese Patent No. 4634568 (Patent Document 3) discloses a middle-floor floating fish reef equipped with a radio wave transmitter that does not transmit at the mooring position but operates when the mooring is released and ascends.
Japanese Patent No. 4061577 (Patent Document 4) discloses a fish reef outflow alarm device with a GPS device in which a floating fish reef flows out and a pressure switch is activated in response to a change in seawater pressure to activate the alarm device.

However, the alarm means for underwater moorings described in the above document has the following problems. (1) A relatively expensive and precise device such as GPS must be provided on the underwater mooring object, and these devices must be housed in a special container with high water tightness.
(2) If there are many underwater moorings, one or more GPS devices must be provided for all of these underwater moorings.
(3) In the alarming means using the GPS device, the underwater mooring thing flows out and the GPS device does not operate unless the GPS device floats on the water surface. Therefore, the state of the underwater mooring object is not known until the outflow occurs. In addition, since the normal state is unknown, it is not known even if GPS devices may not work due to adhesion or failure of deposits such as shells, etc., and even when underwater moorings flow out There are things you can't do.
(4) Since it is not possible to easily inspect or replace equipment when a malfunction or other malfunction occurs, monitoring such an underwater mooring object becomes difficult.

Thus, the monitoring system for underwater moorings as described in the above literature is expensive, the state monitoring is unstable, and it is highly likely that it will be difficult to continue the state monitoring due to equipment failure, etc. There is a problem in that the reliability is low because a failure such as a failure occurs in the device and it is not known. And, for these reasons, the current situation is that the diffusion has not progressed easily.
The present invention has been made to solve the above-mentioned problems all at once, can monitor the state of underwater moorings at low cost, has a wide monitoring range, is accurate, and continues even if a failure occurs. It is an object of the present invention to provide an underwater mooring condition monitoring system having a simple configuration capable of monitoring conditions.

  In order to achieve the above object, the underwater mooring monitoring system according to claim 1 is an underwater mooring monitoring system for monitoring the state of mooring installed underwater or on the surface of water. Transmitting means for receiving the received signal, receiving means for receiving the signal transmitted from the transmitting means provided on the ship, position information generating means for generating position information of the ship, and signal received by the receiving means Transmitting means for transmitting the position information to the management center; receiving means provided in the management center for receiving the signal and the position information transmitted from the ship; and from the signal and the position information to the underwater And a state determining means for determining the state of the mooring object.

For example, as described in claim 2, the state determination unit compares the position information of the underwater mooring object set in advance with the position information of the ship received from the ship, And when the signal from the ship received by the receiving means of the management center includes the signal from the transmitting means, it is determined that the underwater moorings have not flowed out. It may be.
According to a third aspect of the present invention, the state determination means includes a plurality of determination results based on the signals received from a plurality of the ships and the position information, wherein at least one of the determination results is the other determination result. When it is different from the above, it may be determined that the underwater moorings have flowed out.

  According to the above configuration, when the ship enters the predetermined sea area where the underwater mooring object is moored, the receiving means of the ship receives the signal from the transmitting means. This signal is transmitted to the management center by the transmitting means together with the position information of the ship by GPS or the like. The state determination means of the management center that has received the signal and the position information determines the state of the underwater mooring object from the position information of the ship, the position information of the underwater mooring object set in advance, and the signal. For example, when an underwater mooring item flows out by cutting a mooring line and a signal is not received within the preset sea area of the underwater mooring item, an alarm is issued that the underwater mooring item has flowed out.

The position of the underwater mooring object can be specified by receiving the signal of the transmission means at three different positions. The three different positions can be obtained by three different ships or by moving one ship and changing its location. That is, as described in claim 4, the state determination means is included in the position information of the plurality of ships or the plurality of position information obtained by movement of the ship and the signal received from the ship. You may make it pinpoint the position of the said underwater mooring thing from the signal from a transmission means.
As described in claim 5, a plurality of the transmitting means may be arranged apart from each other in the water depth direction of the underwater mooring thing.
If it does in this way, when the underwater mooring thing is long in the depth direction, it can be known which part has flowed out. In addition, as described in claim 6, by using one or both of a water depth sensor and the water temperature sensor as the transmitting means, a water temperature distribution for each depth can be obtained.

The signal including the identification code for identifying the ship transmitted from the ship , the identification code for identifying the underwater mooring thing, the transmission means, and the ship attached thereto , respectively, You may enable it to identify the said underwater mooring thing, the said transmission means, and the said ship from the positional information on a ship.

As described in claim 8, the underwater mooring object may be a floating fish reef, and the boat may be a fishing boat that sails with the artificial fish reef as a target. In this case, as described in claim 9, the transmitter includes a water depth sensor that transmits a signal related to water depth information or a water temperature sensor that transmits a signal related to water temperature information. It becomes possible to form fish school distribution information by combining the detection information by the detection means and the water depth information from the water depth sensor or the water temperature information from the water temperature sensor .

Since the present invention is configured as described above, it is only necessary to provide an underwater mooring object with an inexpensive sensor for transmitting any signal, and a GPS device mounted on a ship can be used. Since the entire system configuration can be simplified, the state of the underwater moorings can be monitored at a low cost. In addition, since devices such as GPS are mounted on a ship, even if a failure or other problem occurs, inspection and replacement can be easily performed, and signals can be received by a plurality of ships. For example, the state of the underwater moorings can be continuously monitored through other ships. In addition, since the signal from the sensor provided in the underwater mooring is received by the ship's receiver, the operation status of the sensor can be confirmed regularly or irregularly on a daily basis. If the signal from the sensor cannot be normally received due to adhesion or failure, it is possible to quickly remove or replace the deposit. Furthermore, since the GPS device is provided on the ship floating on the water, a wide range of state monitoring can be ensured. In addition, by receiving signals from a plurality of ships, it is possible to monitor the state of the underwater moorings at short time intervals and to accurately monitor the state.
Furthermore, in the present invention, it is possible to distribute information on the state of underwater moorings created at the management center by WEB or e-mail over the Internet, etc., and grasp the position and state of underwater moorings even in remote locations. can do.

Hereinafter, preferred embodiments of the present invention will be described in detail.

The determining unit 32 determines that the floating fish reef 1 has been discharged. And a database 34 for storing data such as the installation position of the alarm unit 33 and payaos 1 alert the.

[Floating fish reef]
The floating fish reef 1 is known, for example, in Japanese Patent Application Laid-Open No. 2001-314135, Japanese Patent Application Laid-Open No. 2012-152178 and Japanese Patent No. 3335497 by the applicant of the present application, and floats on the reef body main body 10 having a fish collecting and attracting effect. As shown in FIG. 2, the reef body main body 10 is moored in a floating state at a predetermined water depth by being connected to a mooring anchor 13 fixed to the sea floor by a mooring line 12.
Although the transmission part 11 which transmits a signal with respect to the ship 2 may be arrange | positioned only in one place of the floating fish reef 1, you may arrange | position in multiple places. For example, as shown in FIG. 2, transmitters 11 a, 11 b, 11 c... May be arranged at the upper end of the reef body body 10, near the seabed of the mooring line 12, and between the seabed and the reef body body 10. .

When monitoring a plurality of floating fish reefs 1 or when a single floating fish reef 1 has a plurality of transmitters 11a, 11b, 11c,... It is preferable that one of the transmission units 11a, 11b, 11c,.

A distribution map can be created, and it becomes easy to predict the types of fish and fish catches collected in the floating fish reef 1.

[Ship]
The type of the ship 2 is not particularly limited, but when the underwater mooring is the floating fish reef 1, it is mainly a fishing boat.
In recent years, since fishing boats equipped with a fish finder equipped with a GPS function have become common, the GPS signal receiving unit 23 and the position information creating unit 24 can use those of an existing fish finder, Can use existing communication antennas. Therefore, it is only necessary to newly provide the ship 2 with a receiving unit 21 that receives signals transmitted from the transmitting units 11a, 11b, 11c.
It is preferable to attach an identification code for identifying each of the ships 2 to the signal transmitted from the transmission unit 22. In the database 34, the identification code and each ship 2 are associated with each other and registered in advance.

[Management Center]
The management center 3 is mainly installed on land. If the underwater mooring is the floating fish reef 1, it may be provided in a fishery cooperative or other facility that manages fishing using the floating fish reef 1.
In the database 34, an identification code for each floating fish reef 1, an identification code for each of the transmitters 11a, 11b, 11c... In each floating fish reef 1, and an identification code for each ship 2 are registered in association with each other. The location information of the sea area where the floating fish reef 1 is installed is registered in association with each floating fish reef 1.

  The “sea area” means an area where the receiving unit 21 can receive signals from the transmitting units 11a, 11b, 11c... When the floating fish reef 1 is normally moored. It refers to a circular area centered on the mooring position (area indicated by symbol R in FIG. 4). Although the width of the sea area depends on the output of the transmitting parts 11a, 11b, 11c,.

  The receiving unit 31 that receives a signal from the ship 2 can use an existing antenna provided for communication in these facilities. The determination unit 32, the database 34, and the alarm unit 33 can use a commercially available personal non-computer (PC). In this case, an application program for operating the underwater mooring monitoring system of the present invention is installed in the PC.

[Operation of underwater mooring monitoring system]
FIG. 3 is a flowchart for explaining a procedure executed by the application program. Any application program can be used as long as it can execute this procedure.
When the application program of the PC is activated after the ship 2 heads for the target sea area (step S1), the position information of the ship 2 is input to the PC via the receiving unit 31, and the transmitting unit 11a of the floating fish reef 1 , 11b, 11c... Starts receiving signals (step S2). The position of each ship 2 is specified by the position information of the ship 2 (step S3).

Further, the position information of the sea area where the floating fish reef 1 is installed is read from the database 34 (step S4), and is compared with the position information of each ship 2 specified in step S3 (step S5).
When the position information of the ship 2 coincides with the position information of a certain sea area, the determination unit 32 specifies the sea area R in which the ship 2 has been entered (step S6) and also specifies the floating fish reef 1 corresponding to the sea area R ( Step S7). If the received signal includes a signal related to the floating fish reef 1 (step S9), the process returns to step S2 and repeats the process as no outflow.

On the other hand, if the received signal does not include a signal related to the floating fish reef 1 (step S9), an alarm generation process is performed on the assumption that the floating fish reef 1 has flowed out (step S11).
Although not particularly shown in FIG. 3, when the received signal includes a signal related to the floating fish reef 1 different from the floating fish reef 1, the database 34 is referred to the other floating fish reef 1. It identifies and performs the alarm generation process that the other floating fish reef 1 has flowed out.
In this alarm generation process, it is possible to display on the PC screen that there is a possibility that it has flowed to which floating fish reef 1 in which sea area, or display it on the WEB via the Internet or a mobile phone designated in advance. It includes transmitting to a mobile terminal such as a telephone or a smartphone.

As a result of comparing the position information of the sea area read from the database 34 and the position information of each ship 2 (step S5), if they do not match, it is determined that the ship 2 has not entered any sea area. Next, it is determined whether or not a signal from the floating fish reef 1 has been received (step S8). If the signal from the floating fish reef 1 is included in the received signal, the floating fish reef 1 is specified from the signal (step S10), and an alarm generation process is performed on the assumption that outflow has occurred in the floating fish reef 1 (step S11).
If the signal from the floating fish reef 1 is not included in the received signal, the process returns to step S2 and is repeated.

FIG. 4 is several pattern diagrams showing the relationship between the position of the ship 2 and the sea area R.
(A) is a case where there is no outflow in the floating fish reef 1. In this case, the information regarding the specific sea area R when the ship 2 enters the specific sea area R and the signal receivable area S from the specific floating fish reef 1 installed at the center of the specific sea area R (FIG. 4 (c) and (d)) are substantially the same. At this time, since the signal regarding the specific floating fish reef 1 transmitted from the transmitting unit 11 is received, the determination unit 32 determines that there is no outflow (moored at a normal position) with respect to the floating fish reef 1 ( (See “match” in step S5 in FIG. 3, “Y” in S6, S7, and S9).

  (B) is a first pattern in the case where an outflow has occurred in the floating fish reef 1, in which the floating fish reef 1 has completely flowed out of the specific sea area R. Even if the ship 2 enters a specific sea area R, a signal from the floating fish reef 1 is not received (see “N” in step S9), and the determination unit 32 determines that the floating fish reef 1 has flowed out and issues an alarm. (See step S11).

  (C) is the second pattern when the outflow occurs in the floating fish reef 1. When the ship 2 receives a signal related to the floating fish reef 1 on the way to the specific sea area R (reception of the signal from the transmitting unit 11). In the possible area S). Since the position information of the ship 2 does not match the position information of any sea area R (see “mismatch” in step S5), a signal related to the floating fish reef 1 is received in this state (see “Y” in step S8). The determination unit 32 determines that the floating fish reef 1 has flowed out, identifies the floating fish reef 1 that has flowed out (see step S10), and issues an alarm (see step S11).

(D) is a third pattern in the case where an outflow occurs in the floating fish reef 1. The outflowing floating reef 1 is located in the vicinity of a specific sea area R, and the signal reception area S from the floating fish reef 1 This is a case where a specific sea area R partially overlaps. In such a case, if the ship 2A enters the overlapping portion of the sea area R and the receivable area S, “Y” in step S9 from “match” in step S5 in FIG. Can not judge outflow.
Therefore, in such a case, based on the information from the plurality of ships 2A, 2B, 2C..., At least one of the plurality of ships 2A, 2B, 2C. When a determination result different from that of the other ship (the ship 2A) is generated in 2C), it is determined that the floating fish reef 1 has flowed out, and an alarm may be issued (step S11).

  By the above procedure, the underwater mooring monitoring system of the present invention can determine whether or not the underwater mooring (floating fish reef 1) is not flowing out. Moreover, according to the underwater mooring thing monitoring system of this embodiment, the position of the floating fish reef 1 can be specified from the position information of the ship 2 and the signal from the floating fish reef 1. That is, the position of the floating fish reef 1 that is an underwater mooring object can be specified by receiving signals from the transmitter 11 at three different positions. Therefore, if at least three of the plurality of ships 2A, 2B, 2C... Are receiving the signal as described above, the position of the floating fish reef 1 can be specified from the three ships. It becomes easy to find and collect the spilled floating reef 1. The position of the floating fish reef 1 can also be specified by receiving signals at three different positions while one ship 2 moves.

The present invention is not limited to the above embodiment.
For example, in the above embodiment, a floating fish reef has been described as an example, but the present invention is not limited to a floating fish reef, and other than a floating fish reef, as long as it is an underwater mooring object moored in a floating state in the sea or fresh water. Applicable.
Further, when the ship 2 includes a fish finder, if the transmitters 11a, 11b, 11c,... Of the floating fish reef 1 are water depth / water temperature sensors, the fish finder detection information and the water depth / Information on fish school distribution can be formed from the water depth and water temperature information from the water temperature sensor. By providing a plurality of floating fish reefs 1 at predetermined intervals, it is also possible to form information regarding a three-dimensional fish school distribution. Such fish school distribution information forming means may be provided in the ship 2 or in the management center 3.
Moreover, when the reception results from the plurality of ships 2, 2... Entering the specific sea area R do not match, for example, all the ships 2, 2. The state of the underwater mooring thing may be determined based on the reception result from.

  The underwater mooring monitoring system of the present invention is not limited to being in the sea or fresh water, and can be widely applied in addition to floating fish reefs as long as they are underwater or moored underwater or suspended on the water surface. Is possible.
