[0001] The invention relates to the technical field of marine engineering, and in particular to an integrated device for monitoring and predicting the motion state of a ship. Background Art

[0002] When a ship is sailing on the sea, due to the influence of sea waves and extreme weather, the ship often produces irregular movements, that is, it is difficult for the ship to sail along the predetermined course, which makes the ship's movement operation complicated and challenging.

[0003] In order to overcome the above problems, it is necessary to receive and monitor the motion data of the ship so that the operator can better and more timely grasp the navigation status of the ship, and make correct predictions and operations.

However, although this method can facilitate the ship operator to grasp the motion status of the ship, it requires the installation of various sensors, receivers and display terminals in advance, which is troublesome on the one hand and will increase the navigation cost of the ship on the other hand.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1 and Figure 2 , an integrated device for monitoring and forecasting the motion state of a ship, comprising a portable computer body 100, a data acquisition module 200, a central processing module 300 and a communication module 400, wherein the portable computer body 100 comprises a display screen 101, the display screen 101 and the portable computer body 100 are hingedly arranged, a keyboard 102 is also arranged on the top surface of the portable computer body 100, and a handle 103 is arranged on one side wall of the portable computer body 100. Therefore, the combined appearance of the portable computer body 100 and the display screen 101 is similar to that of a notebook computer, and has the advantages of being easy to carry and store.

[0035] Furthermore, the data acquisition module 200 includes an inclination sensor 201 model (PSD-S1) and an acceleration sensor 202 (model Dytran7705A1). The inclination sensor 201 and the acceleration sensor 202 are both arranged in the portable computer body 100, and there are six acceleration sensors 202 in total. Three acceleration sensors 202 are respectively arranged on the left and right sides of the portable computer body 100. The three acceleration sensors 202 located on the same side of the portable computer body 100 are respectively used to detect the acceleration in the X-axis, Y-axis and Z-axis directions; since the ship has six degrees of freedom in six directions, including up, down, left, right, front and back, during navigation, in order to more accurately monitor the movement state of the ship, it is necessary to monitor the acceleration of the ship in the X-axis, Y-axis and Z-axis directions.

[0036] In addition, the central processing module 300 is arranged inside the portable computer body 100, the inclination sensor 201 and the acceleration sensor 202 are both communicated with the central processing module 300, and the signal output end of the central processing module 300 is connected to the display screen 101; the communication module 400 is arranged inside the portable computer body 100, and the central processing module 300 is connected to the network through the communication module 400 to obtain weather information and ship route information.

[0037] In the specific application process of this embodiment, the inclination sensor 201 and the acceleration sensor 202 transmit the monitoring results to the central processing module 300 in real time, and the central processing module 300 also obtains weather information and ship route information through the communication module 400. Finally, the central processing module 300 predicts the acceleration and inclination data of the next few days or hours based on the historical acceleration, inclination data, weather information and route information, thereby playing the monitoring and forecasting functions.

[0038] Example 2: Please refer to Figure 1 - Fig. 9 The embodiment of the present application also proposes an integrated device for monitoring and predicting the motion state of a ship. The difference between this embodiment and the first embodiment is that: an embedded groove 104 is provided on both sides of the portable computer body 100, and a rotating part 500 is rotatably provided in the embedded groove 104; the three acceleration sensors 202 located on the same side of the portable computer body 100 are all arranged on the same rotating part 500. A main shaft 107 is provided at one end of the inner part of the embedded groove 104, and one end of the rotating part 500 is rotatably connected to the main shaft 107. When the rotating part 500 is parallel to the side wall of the portable computer body 100, the rotating part 500 is completely retracted into the embedded groove 104. That is, the rotating part 500 can be retracted into the embedded groove 104 or extended outward.

[0039] Furthermore, a torsion spring 108 is sleeved on the outer side of the top of the main shaft 107, and the two torsion arms of the torsion spring 108 are respectively in contact with the inner wall of the rotating part 500 and the inner groove 104; in the natural state, the torsion spring 108 is in a tightened state, and the torsion spring 108 has a tendency to push the rotating part 500 to flip outward. The left and right sides of the top surface of the portable computer body 100 are provided with strip openings 105 that communicate with the inner groove 104, and a blocking block 106 is slidably provided in the strip opening 105, and the bottom end of the blocking block 106 extends into the inner groove 104, and the outer surface of the rotating part 500 is provided with a bayonet 501 for the blocking block 106 to be embedded. When the blocking block 106 is embedded in the bayonet 501, since the torsion spring 108 has a tendency to push the rotating part 500 to flip outward, the blocking block 106 can fit tightly with the bayonet 501, thereby confining the rotating part 500 in the embedded groove 104; when the rotating part 500 needs to extend outward, the rotating part 500 is manually pressed inward to separate the blocking block 106 and the bayonet 501, and then the blocking block 106 is pushed to one side to make the blocking block 106 and the rotating part 500 misaligned, so that the rotating part 500 can automatically extend outward under the action of the torsion spring 108.

[0040] It is worth mentioning that when the rotating part 500 extends outward and there is no external force blocking it, the rotating part 500 can eventually rotate to be perpendicular to the side wall of the portable computer body 100. At this time, the outer surface of the rotating part 500 and the inner end of the embedded groove 104 are in contact with each other, and the position of the rotating part 500 remains fixed.

[0041] In addition, the rotating part 500 is a hollow rod-shaped structure, and a pull-out part 502 is movably provided inside the rotating part 500. A movable opening 503 is opened through the pull-out part 502, and a rotating shaft 504 is rotatably provided inside the movable opening 503. A mounting part 505 is provided at the top of the rotating shaft 504. The three acceleration sensors 202 located on the same side of the portable computer body 100 are arranged on the mounting part 505 at intervals along the length direction of the mounting part 505. A spring ball 506 is fixedly embedded at the inner end of the pull-out part 502, and a positioning groove 507 adapted to the spring ball 506 is opened on the inner wall of the rotating part 500 near the end. The outer end width of the pull-out part 502 is greater than the width of the opening end of the rotating part 500, so as to prevent the pull-out part 502 from being completely retracted into the rotating part 500.

[0042] The rotating shaft 504 is provided with a driven gear 508 fixedly sleeved outside, and a driving rack 509 is slidably connected in the movable opening 503, and the driving rack 509 meshes with the driven gear 508. A connecting block 510 is provided inside the rotating part 500 and at one end close to the main shaft 107, and the connecting block 510 and the driving rack 509 are connected by a traction rope 511; when the steel ball of the spring contact ball 506 is embedded in the positioning groove 507, the traction rope 511 is in a tightened state, and the length direction of the mounting part 505 is perpendicular to the length direction of the drawer 502. The driving rack 509 is elastically connected to the movable opening 503 through a reset spring 512. When the drawer 502 is completely retracted into the rotating part 500, the traction rope 511 is in a relaxed state, and the length direction of the mounting part 505 is consistent with the length direction of the drawer 502. That is, when the drawer 502 extends outward, the traction rope 511 is gradually straightened and tightened, and the traction rope 511 can pull the active rack 509, thereby driving the driven gear 508 to rotate 90 degrees, so that the mounting portion 505 is parallel to the side wall of the portable computer body 100.

[0043] In the specific application process of this embodiment, it should be noted that, since the ship has a tendency to sway left and right during navigation, if the acceleration sensor 202 is set on one side of the hull, then its detection result cannot represent the acceleration of the ship itself; if the acceleration sensor 202 is set at the center of the ship, then it cannot reflect the acceleration of the ship when it sways left and right. Therefore, in order to make the device more intuitive and accurate in monitoring the ship's motion status information, it is necessary to place the portable computer body 100 on the central axis of the ship, and then expand the two rotating parts 500 outward, and then pull out the pull-out part 502, so that the three acceleration sensors 202 located on both sides can respectively detect the acceleration information of both sides of the ship.

[0044] In addition, it should be noted that, due to the limited size of the device, although the acceleration sensor 202 can be closer to the edge of the ship by extending the rotating part 500 and the pulling part 502 outward, it is actually still far away from the edge of the ship. Therefore, in order to more accurately reflect the acceleration information of the edges of both sides of the ship, the detection information of the acceleration sensor 202 in this embodiment can be multiplied by the corresponding proportional coefficient, so as to simulate and infer the acceleration information of both sides of the ship.

[0045] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
