(54) SHIPBOARD CONTROL DEVICE

one

The invention relates to shipbuilding, in particular, to shipboard control devices.

A control unit for ship gangway is known, comprising a mode setter associated with executive mechanisms for moving the gangway section and its stopper, and sensors for the positions of the gangway section and the stopper, connected to the corresponding signaling devices 1.

The disadvantage of the prior art device is insufficient reliability of its operation.

The purpose of the invention is to increase the reliability of the device.

The goal is achieved by the fact that the device is equipped with the first and second logical And elements, one of the inputs of which is made inverse, and the first and second logical elements of the BAN, the first direct input of the first And element connected to the first output of the work, the second direct input of the same element to the output of the first sensor of the position of the stopper, inverse 1IND to the output of the first sensor of the position of the gangway section, and the output to the actuator of the movement of the gangway section, the first BANNER element is connected with its direct input to the first output of the operating mode setter, the inverse input to the output of the first stopper position sensor, and the output to the actuator of the movement of the stopper, the second BANNER element is connected by its direct input to the second output of the setting mode, inverse input to the output of the second sensor of the gangway section, and the output to the first direct input of the second element I and to the executive mechanism for moving the section of the gangway, while the second direct input of the second element I is connected to the output of the second date The position of the gangway section, the inverse input of the same element - with the output of the second sensor of the stopper position, and the output - with the executive mechanism for moving the stopper.

The drawing shows a functional diagram of the ship control unit.

-The device contains a setting device I mode of operation, signaling devices 2-5 positions of the gangway section and stopper (signal lamps) AND 6 logic element, BAN 7 logic element, AND 8 logic element BAN 9 logic element, actuator 10 for moving the gangway section, actuator 11 movement of the stopper, sensors 12 and 13 of the positions of the stopper, sensors 14 and 15 of the positions of the gangway section and the power source 16, the first direct input of the element 6 and 6 is connected to the first output of the setpoint 1, the second direct input of the same element to the output of the sensor and 12, the inverse input to the output of the sensor 14, and the output to the executive mechanism 10, the BANE 9 element is connected by its direct input to the first output of the setting device 1, the inverse input to the output of the sensor 12, and the output to the executive mechanism 11, element BANCH 7 is connected by its direct input to the second output of setpoint 1, - the inverse input to the output of sensor 15, and the output to the first direct input of element And 8 and to the actuator 10, while the second direct input of element And 8 connected to the output of the sensor 15, the inverse input of the same element from the output m sensor 13, and the output with the actuator 11, In addition, the output of the sensor 12 is associated with the detector 2, the output of the sensor 13 with the detector 3 and the inverse input element And 8, the output of the sensor 14 with the alarm 4, and the output of the sensor 15 - with signaling congestion 5.

The control unit of the ship's gangway works as follows.

In the initial position, the gangway section is in a raised position and fixed (pulled in) by a stopper. Power off chains. The warning lamps are not hot. To lower the ganging, the mode dial is moved to the "Lowering. Next, the process of putting off the gangway occurs automatically. In this case, the signal from the output "Lowering the setting device 1 of the operation modes is fed to the first direct input of the logic element, AND 6 and to the direct input of the logical element BANGE 9. The signal generated at the output of the logical element BANGE 9 goes to the actuator 11 for moving the stopper (to the input “Recoil stopper). When the stopper is completely withdrawn, the signal from the sensor 12 is supplied to the second direct input of the logic element 6, the inverse input of the logic element BAN 9 to the signaling device 2. As a result, the signal from the actuator 11 for moving the stopper is removed and a signal is sent to the actuator 10 for moving (at the entrance "Lowering). With

When the gangway section is moved to the extreme position, the gangway position sensor 14 triggers, the signal from its output goes to the inverted input of the AND 6 logic element and to the signaling device 4. The signal from the gangway moving mechanism 10 is removed. The process of lowering the gangway ends. In order to raise the gangways, the setpoint adjuster 1 of the operation modes is set to the "Lift.

After this, the process of lifting the gangway occurs automatically. In this case, the sigal from the output “Lifting knob I is fed to the direct input of the logic element

BANGE 7. From the output of this element, the signal goes to the first direct input of the logic element AND 8 and to the additional mechanism 10 for moving the gangway section. As a result, the gangway moves to the upper position. At full

the lift of the gangway section triggers the sensor 15, the signal from its output goes to the second direct input of the logic element I 8, to the inverse input of the BAN 7 and to the alarm device 5. As a result, the signal

From the actuator 10-movement of the gangway section is removed, a signal is given to the actuator 11 to move the stopper. When the stopper is fully moved, the stopper position sensor 13 triggers, the signal from its output comes

to the inverted input of the logic element AND 8. As a result, the movement of the stopper stops and the detector 5 is triggered. This completes the process of raising the gangway. The device provides enhanced

the reliability of the ship's gangway and the safety of its operation by automating the processes of lowering and lifting.
