Description

Power management device and control system for monitoring power management device

Embodiments of the invention relate to control techniques for monitoring power management devices.

In order to lower the net from the ship, the seat is moved after the netting and netting by simply using a hydraulic drive device (seaming machine).

However, when the ship is moved while the netting and netting are not completely finished by mistake, accidents such as damage to the hydraulic pipe line and hydraulic pump of the netting machine and explosion of the drain pipe occur due to the weight of the net and the moving speed of the ship.

Such a seismic net accident is a type of accident that frequently occurs during operation when the net is inevitably thrown into the sea because the hydraulic pressure of the seismic net is not operated, or the hydraulic operating oil leaks and damages the sea environment.

Accordingly, there is a need for a technique for preventing a seismic trap accident caused by an operation mistake or an unintended movement of a ship. In addition, a technology is needed to solve the problem of accurate speed measurement due to waves and currents at sea.

Here, the ship movement information may be the ship speed, the ship's movement path, and the ship's traveling direction. Specifically, the vessel information estimator 120 may estimate the vessel speed, the vessel's movement path, and the vessel's traveling direction using the coordinates of the vessel 1 obtained from the received GPS information. Here, since the method of estimating the ship speed, the movement path of the ship, and the direction of the ship using GPS information (ship coordinates) is a known technique, a detailed description thereof will be omitted. In addition, the ship information estimator 120 may use a moving average filter to remove noise of GPS information.

When a warning signal is generated, the control unit 130 may generate a cut-off signal to cut off the power provided to the trap 2 through the power cut-off unit 140 in order to immediately stop the trap 2. That is, the nether power management system determines that the case where the ship 1 is formed to the left or the right than the case where the traveling direction is formed in the front is a more dangerous situation, so that when the ship 1 moves to the front, the nether 2 It is possible to generate a warning signal and a blocking signal at a speed lower than the speed set to stop (the second set speed).

The power cutoff unit 140 may cut off the power provided to the netting net 2 according to the cutoff signal received from the control unit 130 . For example, the power cutoff unit 140 may be inserted in the middle of a power supply line to cut off power. Meanwhile, the power cutoff unit 140 may further include a device capable of electrically connecting and disconnecting the power supply line manually by a worker.

The notification unit 150 may generate a notification according to at least one of a caution signal and a warning signal. The notification unit 150 may include at least one of a speaker capable of generating a notification sound and a lighting unit capable of displaying an alarm light. Here, the warning signal may mean that the degree of danger is higher than that of the warning signal, and for example, the warning signal may have a higher sound intensity than the warning signal.

The display unit 160 may provide the vessel movement information received from the vessel information estimation unit 120 on a screen that a worker can check. For example, as shown in FIG. 3 , the display unit 160 may display the location of the ship 1, ship speed, date and time on the screen. Also, the display unit 160 may display the first set speed and the second set speed set by the user on the screen.

The wireless communication unit 170 may perform wireless communication with the smart device 200 of the person in charge. For example, the wireless communication unit 170 may be communicatively connected to the worker's smart device 200 through Wi-Fi, Bluetooth, Near Field Communication (NFC), and the like. The wireless communication unit 170 may receive a stop signal from the smart device 200 . The stop signal may be a signal input to the smart device 200 by the operator to stop the sheep. In addition, the wireless communication unit 170 may receive the set speed from the smart device (200). The set speed may be a speed input by an operator for power management. In addition, the wireless communication unit 170 may transmit the vessel movement information estimated through the vessel information estimation unit 120 to the smart device 200 .
