Description

Technical Field

[0001] The invention belongs to the technical field of ship positioning, and in particular relates to a nautical chart operation assessment comparison and recording device and method. Background Art

[0002] When a ship is sailing at sea, in order to ensure the safety and accuracy of navigation, it is necessary to continuously observe and determine the exact position of the ship in real time, and draw the position of the ship on the nautical chart according to certain specifications, so as to achieve continuous regular nautical chart operation. For a long time, the training and assessment of the observation and positioning, and nautical chart drawing and calculation capabilities of seafarers have mostly been carried out during the navigation of the ship in the form of regular nautical chart operations. It is necessary to complete the ship's position marking, route drawing, heading and time marking on the nautical chart in real time. After the operation is completed, the ship's positioning accuracy is tested, and the drawing and calculation standardization of the nautical chart operation is checked and corrected, so as to continuously promote the improvement of the nautical chart operation ability of seafarers. Therefore, the training and assessment of nautical chart operations have always been a key link in the training and evaluation of practical skills of navigation operations.

[0003] At present, training related to navigation practice needs to be carried out while the ship is sailing. In order to improve the training efficiency, the training and assessment of nautical chart operations are often carried out by multiple people at the same time during the navigation of the ship. There are many trainees. Since the drawing operation is carried out on the actual nautical chart, and the nautical chart is an important navigation book material and must be reused, the last drawing result must be erased on the nautical chart when conducting each nautical chart operation training. This means that when conducting current chart operation training, if the results of the chart operation need to be retained, either the charts of a specific sea area are specially purchased for assessment work, and the paper results are archived and retained after the assessment and correction are completed, or the chart operation results are manually photographed with a camera and manually photographed one by one for preservation. However, this method is easily affected by the size of the chart and the intensity of light, and the effect is often poor, and the recorded results are difficult to effectively retain. On the other hand, the current practice for checking the accuracy of ship positioning in chart operations is to manually draw the satellite positioning track of the ship on transparent paper, and then mark the allowable error range on the transparent paper, and finally overlap the marked transparent paper on the chart, compare the ship positioning position on the chart with the satellite positioning track on the transparent paper, and realize the inspection of the actual ship positioning accuracy of the navigators. Since the satellite positioning track needs to be manually marked on the transparent paper, the workload is large. At the same time, the manual secondary marking of the track as a comparison benchmark will introduce drawing errors, which will also have a certain impact on the assessment and evaluation.

[0004] Through the above analysis, the problems and defects of the prior art are as follows:

[0005] (1) When recording chart operation assessment, the use of paper charts is expensive and inflexible. Manual photography to preserve chart operation results is inefficient. It is also affected by the size of the chart and the intensity of light. The effect of manual photography of the chart surface is poor and the speed is slow. The record results are difficult to retain effectively and cannot meet the needs of digital correction and archiving management of chart operation assessment;

[0006] (2) Manually drawing on transparent paper as a reference for ship positioning accuracy assessment is labor-intensive. Using manual secondary marking as a reference for comparison increases the reference error, which, to a certain extent, affects the accuracy of ship positioning accuracy inspection and evaluation in nautical chart operations. Summary of the invention

[0007] In view of the problems existing in the prior art, the present invention provides a nautical chart operation assessment comparison and recording device.

[0008] The present invention is implemented in this way: a nautical chart operation assessment comparison and recording device comprises:

[0009] Fixed table, flat panel display, adjustable bracket, HD camera, fill light, computer host, satellite positioning receiving module;

[0010] Fixed table: used to fix and connect flat panel monitors and adjustable stands;

[0011] Two guide rails along the long side of the fixed table: the flat panel display can move along the two guide rails in the X-axis direction on the fixed table;

[0012] High Definition Camera: Used to record the ship’s track reference highlighted on the chart and flat panel display.

[0013] Furthermore, the fill light is used as a supplementary light source for high-definition camera shooting and recording.

[0014] Furthermore, the adjustable bracket: the high-definition camera and the fill light are installed on the fixed table through the adjustable bracket, and the high-definition camera can be moved in the height direction (Z axis) and the short side direction (Y axis). Combined with the guide rail (X axis) on the fixed table, the shooting range of the high-definition camera can be adjusted in three dimensions.

[0015] Furthermore, the flat panel display is used to highlight the satellite positioning track reference and the error tolerance curve of the ship, so as to facilitate the comparison between the chart drawing result and the track error tolerance curve.

[0016] Furthermore, the computer host: receives the track data of the satellite positioning module, calculates the track reference and the error allowable range curve, drives the flat panel display to display, and receives and records and saves the high-definition camera shooting data.

[0017] Furthermore, the Beidou satellite positioning receiving module receives Beidou positioning information and outputs real-time track data of the ship.

[0018] Furthermore, the flat-panel display has damping hinges at both ends, which can fix the nautical chart to be recorded tightly on the display screen of the flat-panel display. The high-definition camera simultaneously records the nautical chart operation results and the ship track benchmark and error tolerance range curve highlighted on the flat-panel display closely below.

[0019] In combination with the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solutions to be protected by the present invention are as follows:

[0020] First, the present invention designs a nautical chart operation assessment comparison and recording device, which highlights the Beidou satellite positioning track and the error tolerance range curve of the ship through a flat-panel display installed on a fixed table. A high-definition camera and a fill light are installed on the fixed table through an adjustable bracket. The display and the high-definition camera are connected to a computer host. The computer host can be externally connected to a Beidou satellite positioning receiving module to independently receive the ship's track position in real time as a comparison benchmark. The flat-panel display can move along two long-side directions (X-axis) on a fixed plane, and cooperate with the high-definition camera to move in the height direction (Z-axis) and the short-side direction (Y-axis) through an adjustable bracket. Through the above device, the nautical chart is closely fixed on the flat-panel display, and the nautical chart drawing result can be compared with the ship track benchmark and the error tolerance range curve highlighted on the flat-panel display. At the same time, the nautical chart drawing and track benchmark comparison results can be efficiently saved, thereby solving the problem that the nautical chart operation results are difficult to save and the comparison efficiency is low in the current nautical chart operation practical assessment.

[0021] 1. There is a flat-panel display on the fixed table, which can highlight the Beidou satellite positioning track of the ship and the error tolerance curve, which is used for positioning accuracy comparison in chart operation assessment;

[0022] 2. There are high-definition cameras and fill lights on the fixed table, which can be used to conveniently record the chart information of nautical chart operations and the comparison results between the ship positioning position on the chart and the satellite positioning benchmark.

[0023] The present invention uses a flat panel display installed on a fixed table, in conjunction with a high-definition camera and a fill light, to introduce the real-time track information of the ship output by the Beidou satellite positioning module, so that the flat panel display can highlight the ship's track reference and the error tolerance curve, which is convenient for comparing the ship positioning results of the navigators with the positioning reference during the nautical chart operation assessment, while completing the drawing record of the nautical chart operation. Through this device, the positioning reference comparison and preservation in the nautical chart drawing and assessment can be completed efficiently, and the nautical chart can be stored and erased immediately after comparison, meeting the actual needs of repeated use of nautical charts in actual operations, and also facilitating the subsequent digital correction and archiving of the saved nautical chart operation results, solving the problem of difficult preservation of nautical chart operation results and low comparison efficiency in the current nautical chart operation practical training assessment.

[0024] Second, as auxiliary evidence of the inventiveness of the claims of the present invention, it is also reflected in the following important aspects:

[0025] (1) The expected benefits and commercial value of the technical solution of the present invention after transformation are:

[0026] 1. It can improve the quality of training for maritime personnel. The present invention has good use value in maritime operation training, chart assessment correction and recording. After transformation, the technical solution can solve the problems of difficult preservation of chart operation results and cumbersome manual comparison in the current practical training and assessment of chart operations. It can significantly improve the efficiency of maritime operation assessment, further improve the training level of maritime operators, and provide strong technical support for the subsequent realization of digitalization and intelligent correction of chart assessment operations. It has good expected benefits for improving the quality of maritime personnel training.

[0027] 2. It can significantly reduce the cost of chart operation assessment. In traditional chart operation assessment, in order to meet the requirements of long-term archiving of assessment papers, special assessment charts must be printed for assessment and storage. At present, the purchase price of each ordinary copperplate printed marine chart is 60-100 yuan. Calculated based on the annual assessment of 2,000 people / times, the annual procurement cost of the chart is 120,000-200,000 yuan. Calculated based on the test paper storage period of 5 years, in order to meet the storage requirements, the chart assessment alone requires the purchase of 600,000-1 million yuan of assessment charts. After using the present invention, since the chart assessment results can be digitally stored and the assessment charts can be reused, the purchase of assessment charts can be greatly reduced in navigation operation training, which significantly reduces the cost of chart operation assessment and has good commercial value.

[0028] (2) The technical solution of the present invention fills the technical gap in the industry at home and abroad:

[0029] For a long time, the training and assessment of nautical chart operation has been carried out by manual secondary drawing comparison and manual photography and recording, which is inefficient. When the number of people involved in the nautical chart operation training is small, the conflict is relatively low, so there has been no special technical solution. However, with the continuous improvement of the learning requirements of navigation courses, the number of people involved in the nautical chart operation assessment and the number of records are increasing, and the traditional method has become increasingly difficult to meet the actual needs. Therefore, the solution of the present invention fills the technical gap in this application field. At the same time, the technical solution of the present invention can also provide technical support and prerequisites for the subsequent digital archiving management and intelligent correction of nautical chart operations.

[0038] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] like Figure 1 As shown, a nautical chart operation assessment comparison and recording device provided by an embodiment of the present invention includes:

[0040] Fixed table top 1, flat panel display 2, camera 3, fill light 4, adjustable bracket 5, data connection line between fixed table top and computer host 6, damping loose-leaf 7, guide rail 8, computer host 9, Beidou satellite positioning receiving module 10.

[0041] Fixed table 1: used for fixing and connecting the flat panel display 2 and the adjustable bracket 5;

[0042] Two guide rails 8 along the long side of the fixed table 1: the flat panel display 2 can move along the two guide rails 8 in the X-axis direction on the fixed table 1;

[0043] High-definition camera 3: used for photographing and recording the nautical chart and the ship track reference highlighted on the flat panel display 2.

[0044] The fill light 4 provided in the embodiment of the present invention is a supplementary light source used for shooting and recording by the high-definition camera 3 .

[0045] The adjustable bracket 5 provided in the embodiment of the present invention: the high-definition camera 3 and the fill light 4 are installed on the fixed table 1 through the adjustable bracket 5, and the high-definition camera 3 can be moved in the height direction (Z axis) and the short side direction (Y axis). Combined with the guide rail 8 (X axis) on the fixed table 1, the shooting range of the high-definition camera 3 can be adjusted in three-dimensional directions.

[0046] The flat panel display 2 provided in the embodiment of the present invention is used to highlight the satellite positioning track reference and the error tolerance curve of the ship, so as to facilitate the comparison between the chart drawing result and the track error tolerance curve.

[0047] The computer host 9 provided in the embodiment of the present invention receives the track data of the satellite positioning module, calculates the track reference and the error tolerance curve, drives the flat panel display 2 to display, and receives and records the shooting data of the high-definition camera 3.

[0048] The Beidou satellite positioning receiving module 10 provided in the embodiment of the present invention receives Beidou positioning information and outputs real-time track data of a ship.

[0049] The flat panel display 2 provided in the embodiment of the present invention has damping hinges 7 at both ends, which can fix the nautical chart to be recorded tightly on the display screen of the flat panel display 2. The high-definition camera 3 simultaneously records the nautical chart operation results and the ship track benchmark and error allowable range curve highlighted on the flat panel display 2 below.

[0050] like Figure 2As shown, in the nautical chart operation assessment comparison and recording device provided by the embodiment of the present invention, 11 is a display of the ship track reference, 12 is an error allowable range curve, and 13 is a nautical chart outline alignment reference line. After the computer host receives the data from the Beidou satellite positioning receiving module, the ship track reference 11, the error range curve 12 and the nautical chart outline alignment reference line 13 can be highlighted in real time on the flat panel display for comparison with the nautical chart.

[0051] The track reference and error range curves displayed by this device can be set to a display ratio that is consistent with the scale of the nautical chart. The position coordinate system of the Beidou satellite positioning module is the CGCS2000 coordinate system, which is consistent with the domestic ordinary nautical chart coordinate system CGCS2000. The Beidou dynamic positioning accuracy is generally 2-3m (RMS). In the nautical chart operation assessment, if the actual ship position point on the nautical chart is within the error curve range, the positioning accuracy of the positioning point can be considered qualified, and the allowable range of the error curve is generally less than 550 meters. At this time, the Beidou dynamic positioning position of the ship is used as the reference, and its error only accounts for 0.5% of the allowable range of the error curve, which can meet the positioning accuracy requirements of this device.

[0052] like Figure 3 As shown, in the nautical chart operation assessment, comparison and recording device provided by the embodiment of the present invention, 14 is a nautical chart that needs to be assessed, compared and recorded. The nautical chart 14 that needs to be assessed, compared and recorded is superimposed on the top of the flat-panel display, and the nautical chart is aligned with the plane of the flat-panel display according to the nautical chart outline alignment reference line 13 displayed on the flat-panel display. The ship track reference 11 and the error range curve 12 highlighted on the flat-panel display can be mapped on the nautical chart, and the high-definition camera above shoots in real time to complete the comparison and recording of the nautical chart operation results.

[0053] In the embodiment:

[0054] The X-axis refers to the long axis on the fixed table;

[0055] The Y axis refers to the short axis on the fixed table;

[0056] The Z axis refers to the height direction;

[0057] CGCS2000 refers to China's latest national geodetic coordinate system, which is called China Geodetic Coordinate System 2000 in English. The longitude and latitude coordinates given by the Beidou positioning module are the values ​​under the CGCS2000 coordinate system, which is different from the civil maritime coordinate system. Figure 1 To.

[0058] RMS refers to the root mean square value, which is a commonly used indicator to describe the size of the error.

[0059] Example 1: Nautical chart operation track recording and comparison based on flat panel display

[0060] 1. Device Preparation

[0061] Install a flat panel display, a high-definition camera, and a fill light on a fixed table, and adjust the position of the camera and fill light through an adjustable bracket. Make sure that the camera is aimed at the flat panel display and covers the entire display area on the flat panel display.

[0062] Start the computer host, connect the Beidou satellite positioning receiving module and the high-definition camera, and open the software interface.

[0063] 2. Operation steps

[0064] 1) The Beidou satellite positioning receiving module is started to receive the ship's satellite positioning data in real time and transmit the data to the computer host.

[0065] 2) The computer host calculates the ship's track reference based on the satellite positioning data and generates an error tolerance curve based on the set assessment standards.

[0066] 3) The flat panel display highlights the generated track reference curve, error tolerance curve and display outline alignment reference line.

[0067] 4) Place the chart close to the display screen of the flat panel display and fix it with loose-leaf pages; adjust the guide rail of the flat panel display to the appropriate position to ensure that all areas can be clearly photographed.

[0068] 5) Start the high-definition camera, automatically adjust the brightness of the fill light, and record the track drawing results on the nautical chart and the reference curve displayed on the flat panel display.

[0069] 6) The data captured by the high-definition camera is transmitted to the computer host in real time to save the captured data and the results of the nautical chart operation.

[0070] 3. Save the results

[0071] After the assessment is completed, all shooting data, analysis deviations and generated assessment report files are stored in the computer host, and the data is exported through the USB interface.

[0072] Example 2: Track shooting process of a three-dimensional adjustable high-definition camera

[0073] 1. Device Preparation

[0074] Install two parallel rails on the fixed table, install an adjustable bracket and a high-definition camera, and connect the fill light and the computer host.

[0075] Adjust the height (Z axis) and short side position (Y axis) of the high-definition camera on the bracket by means of bolts so that the camera faces the center of the flat panel display.

[0076] 2. Operation steps

[0077] 1) The flat panel display is adjusted along the guide rail on the fixed table (X axis) so that the position of the flat panel display is completely matched with the field of view of the high-definition camera.

[0078] 2) Use the bracket to adjust the position of the high-definition camera in three dimensions to ensure that the camera can cover the entire area of ​​the display screen. At the same time, adjust the position and brightness of the fill light to eliminate reflections and dark corners.

[0079] 3) After starting the system, the flat panel display shows the ship's track reference and error tolerance curve.

[0080] 4) Place a nautical chart in the camera field of view and fix it on the display screen with a damping hinge. Use a high-definition camera to capture the track drawing results of the nautical chart and the reference curve displayed on the flat panel display.

[0081] 5) Test the shooting area, adjust the camera focus to ensure the shooting picture is clear, and adjust the shooting parameters to complete the final recording.

[0082] 3. Data analysis and storage

[0083] The captured data is processed and analyzed by the host computer to generate the comparison results of the track reference and error. The final data is stored in the host computer and can be exported.

[0084] These two embodiments respectively explain in detail the actual operation process and application effect of the device from the perspectives of track recording and comparison and three-dimensional adjustment, fully demonstrating the practicality and advantages of the technical solution.

[0085] Figure 4 This is an example of the assessment of nautical chart operations. Based on the assessment observation data, the track operation and chart ship position positioning drawing results at different times from T0 to T6 are obtained respectively. Figure 5 Before the present invention is used, the current nautical chart drawing assessment adopts manual marking of transparent paper to compare and record the legend, and the comparison benchmark needs to be manually marked on the transparent paper, which has low work efficiency and poor effect. Figure 6 The present invention generates and highlights on a flat-panel display a track error range curve and an allowable range of ship position error at a certain moment based on the real-time positioning information of the ship from the Beidou satellite positioning receiving module; at the same time, generates and highlights on the flat-panel display a chart outline alignment reference line based on the longitude and latitude references of the chart for aligning the chart. Figure 7When using the present invention, the assessment chart is fixed closely on the flat-panel display, and the chart outline is aligned with the longitude and latitude datums of the chart, so that the chart drawing result can be compared with the ship track datum and error tolerance curve highlighted on the flat-panel display. In this way, the size, color and line type of various error tolerance thresholds can be adjusted, and the ship position assessment point at a specific time can also be arbitrarily displayed and adjusted according to the assessment or recording needs, thereby facilitating the completion of comparative records.

[0086] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any modifications, equivalent substitutions and improvements made by any technician familiar with the technical field within the technical scope disclosed by the present invention and within the spirit and principle of the present invention should be covered by the protection scope of the present invention.
