[0043] Specifically, the steps of sorting out all basic data involved in the ship position data management business and building a basic database for ship position data management include:

[0044] S11: sort out the engineering number data related to the ship position data management business during the ring segment docking process, and record the names, numbers and serial numbers of all engineering numbers in the basic database, as shown in Table 1 below.

[0045] Table 1

[0046] Serial number Project No. Project Name

[0047] S12: Sort out the operation area data related to the ship position data management business, and record the names and serial numbers of all operation areas in the basic database, as shown in Table 2 below.

[0048] Table 2

[0049] Serial number Working area

[0050] S13: sort out the operation object data related to the ship position data management business, and record the names and serial numbers of all operation objects in the basic database, as shown in Table 3 below.

[0051] Table 3

[0052] Serial number Job Object

[0053] S14: Sort out the operation phase data related to the ship position data management business, and record the names, serial numbers, and sequence numbers of all operation phases in the basic database, as shown in Table 4 below.

[0054] Table 4

[0055] Serial number Operation stage

[0056] S15: Sort out the operation instruction drawings related to the ship position data management business, upload and record all the operation instruction drawings in the basic database in the form of pictures.

[0057] S2: Enter the standard values ​​of the ship position data of the operation object during the operation phase. The standard values ​​of the ship position data include the standard value of the minimum deviation of the center line, the standard value of the maximum deviation of the center line, the standard value of the minimum deviation of the front and rear, and the standard value of the maximum deviation of the front and rear;

[0058] Specifically, when entering the standard value of the ship position data of the operation object in the operation phase, first read the project number, operation area, operation object, and operation phase data stored in the basic database, and then enter the standard value of the maintenance operation object in the operation phase. Among them, the standard value includes the standard value of the minimum deviation of the center line, the standard value of the maximum deviation of the center line, the standard value of the minimum deviation of the front and rear, and the standard value of the maximum deviation of the front and rear.

[0059] For example: set the project number to H9999; the operation area to 1# dock; the operation object to the middle section, and set the standard values ​​at different operation stages, as shown in Table 5 below.

[0060] Table 5

[0061]

[0062] S3: Enter the target point measurement value and the front and rear deviation measurement value of the operation object during the operation stage;

[0063] Specifically, when entering the standard value of the ship position data of the operation object in the operation phase, read the project number, operation area, operation object, and operation phase data stored in the basic database, and then enter and maintain the target measurement value and front and rear deviation measurement value of the operation object in the operation phase. The target measurement value includes target measurement value A, target measurement value B, target measurement value C, and target measurement value D. The front and rear deviation measurement value includes the front and rear deviation measurement value E.

[0064] For example: set the project number to H9999; the operation area to 1# dock; the operation object to the middle section, and enter the actual measured values ​​of the targets in different operation stages, as shown in Table 6 below.

[0065] Table 6

[0066]

[0067]

[0068] S4: Calculate the bow deviation value and the stern deviation value based on the target point measurement value;

[0069] Specifically, after entering the target point measurement value, the specific data of the target point measurement value is obtained, and then the bow deviation value and the stern deviation value are calculated according to the measurement data of the target point measurement value. When calculating the bow deviation value of the operation object, the calculation rule of the bow deviation value is: bow deviation value = target point measurement value A target point measurement value B.

[0070] For example: based on the entered project number H9999, the operation area is 1# dock, and the operation object is the actual measured value of the target in the middle section, the bow deviation value is calculated separately, as shown in Table 7 below.

[0071] Table 7

[0072]

[0073] When calculating the stern deviation value of the operation object, the stern deviation value calculation rule is: tail deviation value = target point measurement value C target point measurement value D.

[0074] For example: based on the entered project number H9999, the operation area is 1# dock, and the operation object is the actual measured value of the target in the middle section, the tail deviation value is calculated separately, as shown in Table 8 below.

[0075] Table 8

[0076]

[0077] S5: Determine whether the centerline deviation and fore-aft deviation are qualified based on the standard value of the ship position data, the bow deviation value, the stern deviation value and the fore-aft deviation measurement value.

[0078] Obtain the standard value of the ship position data entered in step S2, the measured value of the fore-aft deviation in step S3, and the bow deviation value and stern deviation value calculated in step S4. Determine whether the centerline deviation and fore-aft deviation are qualified based on the standard value of the ship position data, the bow deviation value, the stern deviation value, and the measured value of the fore-aft deviation.

[0079] Specifically, when judging whether the centerline deviation before and after the work object is qualified, the qualified judgment rule is:

[0080] The minimum deviation standard value of the center line ≤ the deviation value of the head ≤ the maximum deviation standard value of the center line

[0081] And the minimum deviation standard value of the center line ≤ the tail deviation value ≤ the maximum deviation standard value of the center line.

[0082] For example: Based on the entered project number H9999, the operation area is 1# dock, the operation object is the measured value of the target point in the middle section, and the calculated bow deviation value and stern deviation value, determine whether the centerline deviation of the ship position at different operation stages is qualified, as shown in Table 9 below.

[0083] Table 9

[0084]

[0085] When judging whether the front and rear deviations of the work object are qualified, the qualified judgment rules are:

[0086] The minimum standard value of the front-to-back deviation ≤ the actual measured value of the front-to-back deviation ≤ the maximum standard value of the front-to-back deviation.

[0087] For example: Based on the entered project number H9999, the operation area is 1# dock, the operation object is the target point measured value and the actual value of the front and rear deviations in the middle section, determine whether the centerline deviation of the ship position at different operation stages is qualified, as shown in Table 10 below.

[0088] Table 10

[0089]

[0090] This embodiment also provides a ship position data management and analysis system, which is applied to the above-mentioned ship position data management and analysis method. Figure 2As shown, the ship position data management and analysis system includes a basic data management module, a standard value data management module, a measurement value data management module and a ship position data analysis module. The basic data management module is used to realize the maintenance and management of the basic information required for the ship position data management, mainly including information such as engineering, operation area, operation stage, operation object, layout diagram, etc. The standard value data management module is used to realize the entry of standard value data of the operation object in the operation stage. The measurement value data management module is used to realize the entry of target point measurement value data of the operation object in the operation stage, as well as the front and rear deviation measurement values. The ship position data analysis module is used to realize the calculation of the ship position bow deviation value, the calculation of the ship position stern deviation value, the qualified judgment of the ship position centerline deviation, and the qualified judgment of the front and rear deviation of the ship position.

[0091] In summary, the ship position data management and analysis method of the present invention includes constructing a basic database, maintaining the standard value data of the operation object in the operation stage; performing actual target point measurement values ​​of the operation object in the operation stage, and entering the actual measurement values ​​of the front and rear deviations. By calculating the bow deviation value and the tail deviation value, the qualified judgment of the centerline deviation and the front and rear deviation of the ship position is performed. Furthermore, the present invention can realize the standard definition, actual measurement entry and analysis management of the ship position data during the ring segment floating docking process, thereby further improving the efficiency of ship construction and saving labor costs.
