Description

  The present disclosure relates to a technique for preventing poaching or theft by a suspicious ship at a fishing ground.

  In recent years, preventing poaching or theft by suspicious boats at fishing grounds has become a challenge. Here, it is conceivable for the manager to monitor the fishing ground, but because the manager is on land far from the fishing ground, it is difficult to find a suspicious ship and it is difficult to monitor the fishing ground for 24 hours. It is. Although it is conceivable for the camera to monitor the fishing ground, it is difficult for the camera to detect a suspicious ship depending on the performance of the monitoring range and the like, and it is difficult to monitor the fishing ground at night or in bad weather. Therefore, by monitoring the fishing ground with the radar, it is possible to solve the problem when the manager or the camera monitors the fishing ground (see, for example, Patent Document 1).

JP 2004-318561 A

  In Patent Literature 1, when a monitoring center detects a ship that has entered a fishing ground, the monitoring center transmits an ID confirmation signal and a polling signal to the ship. And if the said ship is a permission ship, it can transmit GPS positioning data with respect to an ID confirmation signal to a monitoring center using the apparatus which should be mounted in a permission ship, and a response signal with respect to a polling signal. It can be sent to the monitoring center. On the other hand, if the ship is a suspicious ship, it cannot have a device to be mounted on a permitted ship, and GPS positioning data cannot be transmitted to the monitoring center in response to the ID confirmation signal. The response signal cannot be transmitted to the monitoring center. Therefore, the monitoring center can determine whether the ship is a permitted ship or a suspicious ship.

  However, although warning a suspicious ship is important in order to prevent poaching or theft by a suspicious ship in a fishing ground, it is not described in Patent Document 1. In the first place, since the suspicious ship cannot have a device to be mounted on the permitted ship, the monitoring center cannot wirelessly communicate with the suspicious ship and cannot warn the suspicious ship. Here, if the suspicious ship is warned, the manager may go to the suspicious ship to warn, but the deterrence is high but the convenience is low.

  Therefore, in order to solve the above-described problem, an object of the present disclosure is to provide a method with high deterrence and simplicity in preventing poaching or theft by a suspicious ship on a fishing ground using a radar.

  In order to achieve the above-mentioned object, a warning is given to the ship detected as having entered the fishing ground with an optical signal or an audio signal. Thereby, it is possible to provide a highly convenient method for preventing poaching or theft by a suspicious ship at a fishing ground using a radar.

  When it is determined that the ship detected to have entered the fishing ground is a ship that has been permitted to operate in the fishing ground, the warning to the ship that has been detected to have entered the fishing ground is canceled, while the ship has been detected to have entered the fishing ground. If it was not found that the ship was authorized to operate at the fishing ground, it was decided to continue to warn the ship that was detected to have entered the fishing ground. Thus, a method having high deterrence can be provided in preventing poaching or theft by a suspicious ship at a fishing ground using a radar.

  Alternatively, when it has been found that a ship that has not yet entered the fishing ground is a ship that has been permitted to operate in the fishing ground, the warning to the ship that will enter the fishing ground is released. Thereby, it is possible to guarantee the operation without issuing a warning to a ship that is permitted to operate in the fishing ground.

  Specifically, the present disclosure includes a radar unit that detects a position of a ship that has entered a fishing ground using a radar, and an intrusion warning unit that warns the ship that has been detected to have entered the fishing ground with an optical signal or an audio signal. When a signal indicating that the ship detected to have entered the fishing ground is a ship that has been permitted to operate in the fishing ground, cancel the warning to the ship that has been detected to have entered the fishing ground, or A fishing ground monitoring, comprising: a warning canceling unit that cancels a warning to a ship that will enter the fishing ground when a signal indicating that a ship that has not yet entered is a ship that is permitted to operate in the fishing ground is received. System.

  In addition, the present disclosure uses a radar unit that detects the position of a ship that has entered a fishing ground using a radar, and warns the detected ship that has entered the fishing ground with an optical signal or an audio signal, and has entered the fishing ground. When it is found that the detected ship is a ship permitted to operate in the fishing ground, the warning to the detected ship is released, or a ship that has not yet entered the fishing ground is the fishing ground. And an intrusion warning unit that cancels a warning to a vessel that will enter the fishing ground when it is determined that the vessel is permitted to operate in the fishing ground monitoring device.

  According to this configuration, it is possible to provide a method having high deterrence and simplicity in preventing poaching or theft by a suspicious ship on a fishing ground using a radar.

  Further, the present disclosure is triggered by the detection that the ship has entered the fishing ground from the open sea across the boundary between the fishing ground and the outer sea, and tracking of the ship detected to have entered the fishing ground is started. The intrusion warning unit (1) detects that the ship has entered the fishing ground from the open sea across the boundary between the fishing ground and the open sea, and (2) the ship is within a predetermined distance to the skeins in the fishing ground. Warning that the ship corresponding to at least one of the fact that it was detected that approached, and (3) that the ship stayed in the fishing ground more than a predetermined time, warn the ship, When a signal indicating that a ship corresponding to at least one of the conditions from (1) to (3) is a ship permitted to operate at the fishing ground is received, among the conditions from (1) to (3) At least either A fishing ground surveillance system and cancels the warning to vessels.

  According to this configuration, it is possible to issue a warning to a suspicious ship that is suspected of (1) entering a fishing ground, (2) approaching a skein, or (3) staying at a fishing ground.

  In addition, the present disclosure detects that it has entered the open sea when it is detected that the fishery has entered the open sea from the open sea after it has been detected that the fishery has been entered from the open sea across the boundary between the fishery and the open sea. It is a fishing ground monitoring system characterized in that the tracking of the ship is continued.

  According to this structure, the escape route of a suspicious ship can be tracked continuously.

  In addition, the present disclosure relates to (4) that it is detected that the ship and the sardine in the fishing ground are indistinguishable, and (5) that the ship is detected to be untrackable in the fishing ground. The vessel or skein crosses the boundary between the fishing ground and the open sea from the fishing ground to the open sea in response to at least one of the ships, or the ike detected from the fishing ground to the open sea. It is a fishing ground monitoring system characterized in that tracking of a ship or a sacrificial vessel that has been detected to have entered the open sea is started, triggered by the fact that it has been detected that the vehicle has been released.

  According to this configuration, not only the suspicious ship that is continuously tracking the escape route, but also the tracking of the suspicious ship within the fishing ground, as in the conditions (4) and (5) above, However, the escape route of a suspicious ship can be tracked, or even if a problem occurs in mooring of a skewer due to a typhoon or the like, a spillout route of the skewer can be traced.

  Further, the present disclosure relates to a ship information processing / providing unit that obtains and processes information on the position of a ship and whether or not operation permission is provided for a ship detected to have entered the fishing ground and provides the information to the terminal of the manager of the fishing ground. , Further comprising a fishing ground monitoring system.

  According to this configuration, for a ship detected to have entered the fishing ground, or for a ship detected to have exited the fishing ground, the fishing ground manager should monitor the information on the position of the ship and the presence or absence of operation permission on the terminal. Can do.

  Thus, according to the present disclosure, it is possible to provide a method with high deterrence and convenience in preventing poaching or theft by a suspicious ship in a fishing ground using a radar.
