Description of the Invention: [Technical Field] The present invention relates to a ship test method and system thereof, and more particularly to a ship swing test method and system therefor. [Prior Art] In general, ships are tested for maneuverability by a number of tests, such as ship maneuvers or ship speed tests. Among them, the ship's maneuver test 9 is carried out at full speed under the sea conditions in accordance with the test, and the right full flight (or left full rudder) is ordered to test the required forward distance, gyroscopic distance and diameter of the ship. The traditional ship whirl test system allows the ship to drop wooden planks or other items at the tail of the ship during the spin process to record the point of travel of the ship. Then, the wooden planks or other items dropped from the stern were taken from the air to record the trajectory of the ship when it was swirling. Therefore, the gyroscopic trajectory can be analyzed to obtain the traverse distance of the forward distance and the diameter of the gyrotron required for the ship to revolve. However, after the plank or other items are dropped from the stern, they will be affected by the current. Drift' makes its position inaccurate to represent the point of travel of the ship. In addition, the traditional boat maneuver test needs to record the position of the ship in the air by means of aerial shooting, which not only costs labor but also costs money. SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a ship convolution test and system thereof, 5 201022085 using a bow to determine the angle of rotation of the ship, and calculating the ship's maneuver test according to the position of the ship at each of the swing angles.

[Embodiment] FIG. 1 is a flow chart of a ship swing test method 6 201022085 according to an embodiment of the present invention. The ship's maneuver test method calculates the value required for the ship's maneuver test by means of the position of the ship and the bow information. Figure 2 is an example of a method of ship maneuvering test. Where the ship is at the initial position of 200, it begins to revolve at 21 〇 with the initial bow. Then, when the ship is in the first position 220, its first bow angle 230 is at an angle of 90 degrees to the initial bow angle 210. When the ship is at the second position 260, its second bow direction 270 and the initial bow direction 210 The angle is 180 degrees. The information of the initial position 200, the first position 220, and the second position 260 is obtained by a Global Positioning System (GPS), a Differential Global Positioning System (DGPS), or other positioning methods. . The initialization bow 210, the first bow 230 and the second bow 270 are obtained by compass. Referring also to Figures 1 and 2, the ship swing test method 1 包含 includes the following steps: In step 110, an initial position of a ship 2 〇〇 and an initial ship direction 210 are obtained. After obtaining the initial position of the ship 2〇〇 and the initial ship's direction 210, the ship is caused to swing (Step 12:8, in detail, the ship can make the right full flight or the left full rudder to make a roundabout. Then 'interval one scheduled Obtaining the current ship's current direction of the ship (step 130), and judging one of the ship's swing angles according to the initial ship's direction and the current bow direction (step 140). The ship's swing angle is the initial ship's direction and current The angle between the ship's gift, that is, the angle at which the ship has been swirled. When the ship's swing angle is 90 degrees, according to a positioning signal, one of the ships is rotated 90 degrees (step 150). In other words, in the ship back 201022085 When the rotation angle is 90 degrees, a positioning device is triggered to obtain the position of the ship's 90-degree rotation by the positioning signal, that is, the position where the ship has been rotated 9 degrees, wherein the initial ship is 21 degrees and the first The angle between a ship and a ship is 90 degrees, so the first position 22 is the position of the ship's maneuver 9 degrees. Next, according to the initial position 200, the initial bow direction 210 and the 90 degree position Calculating one of the ship's forward distance and a convolutional distance (step 160), and continuing to obtain the current ship's heading direction (step 130) at a predetermined time interval, wherein the forward distance is when the ship's swing angle is 9 degrees, the ship is The distance that the initial bow advances toward 210. Therefore, in step 16〇, the forward distance is the first position 220 (the 90 degree position of the ship's swing) is projected at the projection point 220' of the initial bow direction 210 and the initial position 200. a first distance 240. In addition, the swinging lateral distance is the distance between the position of the ship and the initial ship borrowing direction 210 when the ship's turning angle is 9 degrees. Therefore, in step 16〇, the turning lateral distance is the first position 220 and The first ship's direction 210 is a second distance 250. When the swing angle is 180 degrees, according to the positioning signal, one of the ships is rotated 180 degrees (step 17〇> in other words, when the ship's swing angle is 180 degrees, Triggering the positioning device to obtain the 180 degree position of the ship by means of the positioning signal, that is, the position where the bow has been rotated by 18 degrees. [Because the initial bow is 210 and the second bow is 27 The angle between 0 is 180 degrees, so the second position 260 is the 180 degree position of the ship's maneuver. Next, one of the ship's convoluted diameters is calculated based on the initial position 200, the initial ship's direction 210, and the convoluted 180 degree position (step ι 80 > , 201022085 The diameter of the maneuver is the distance between the ship's position and the initial ship's gift to the ship when the ship's angle of rotation is 180 degrees. Therefore, in step 〇8〇, the diameter of the ship is the first position 260 and one of the initial ship's direction 210 The third distance 280. Further, when the swing angle is not 90 degrees or 180 degrees, it can be determined whether the swing angle is greater than 360 degrees (step 190). When the swing angle is greater than 36 degrees, the ship's maneuver test can be ended (step 191). However, when the swing angle is not more than 360 degrees, the ship's current ship's heading is continued (step 130). ® Fig. 3 is a functional block diagram of a ship swing test system in accordance with another embodiment of the present invention. The ship's maneuver test system is used to place the ship's position on the ship under test, and the ship's position information obtained by the electrical compass is used to calculate the value required for the ship's maneuver test. The test system 300 includes a positioning device 31, an electronic compass 320, and a processing device 330. The positioning device 31 and the processing device 330 are established by RS_232, Universal Serial Bus (USB) or other connection methods. link. In addition, the electronic compass 32 〇 and the processing device 330 can also be connected by RS_232, a universal serial bus or other connection method. The positioning device 310 receives a positioning signal by an antenna 34 and calculates the position of the ship based on the positioning signal. In detail, the positioning device 310 calculates the position of the vessel by means of a global positioning system, a differential global positioning system or other positioning method. The processing device 330 can be a computer, a personal digital assistant (or a (4) assistant' PDA) or other device with digital processing capabilities. Processing Device 9 201022085 330 includes an initial module 33A and a measurement module 332. The initial module 33 i acquires an initial position of the vessel by means of the clamping device 310 and uses the electronic compass 320 to obtain an initial bowing direction of the vessel. Then, after the initial module takes the initial position and the initial bow backwards, the ship begins to spin. The measuring module 332 uses the electronic compass 32 to obtain a current ship's heading interval for a predetermined time interval, and judges one of the ship's turning angles according to the initial ship's direction and the current ship's direction. When the swing angle of the ship survey is 90 degrees, the measuring module 332 obtains one of the ship's 9-turn position by using the positioning device 310, and calculates a forward distance of the ship according to the initial position, the initial bow direction and the 90-degree position of the swing. . In addition, the measurement module 332 can also calculate one of the ship's gyroscopic spans based on the initial position, the initial bow direction, and the 90 degree position. However, when the ship's swing angle is 180 degrees, the measurement module 332 uses the positioning device 310 to obtain a 180 degree position of the ship. Then, the measurement module 332 calculates one of the ship's convoluted diameters based on the initial position, the initial bow direction, and the swing 丨 8 位置 position.
