It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1

[0020] like Figure 1-6As shown, a digital ship product online data measurement and verification system includes a data measurement module, which is used to collect hull data and perform online verification on the hull data. The data measurement module is connected to the data verification module through a data sharing platform, and the data measurement module interacts with the data verification module through the data sharing platform, and performs online verification on the hull data through the data verification module. The data measurement module is composed of a data acquisition module, a data processing module, a data storage module, and an interface calling module 1, and the data measurement module is connected to the data sharing platform through the interface calling module 1. The data acquisition module includes an assembly, which is divided into a first assembly 1 and a second assembly 2, and the second assembly 2 is hinged to one side of the first assembly 1. The data acquisition module also includes a main track component 3 slidably arranged on the inner side of the first assembly 1, a plurality of secondary track components 4 fixedly arranged on the inner side of the second assembly 2, a rangefinder 5 for collecting hull data, a position adjustment member 6 for installing the rangefinder 5, and a track adjustment member 7 arranged on the first assembly 1. The data metering module, under different states of the assembly parts, performs adaptive adjustment to various hull structures through the rangefinder 5 in cooperation with the position adjustment part 6, the track adjustment part 7, the main track assembly 3 and the auxiliary track assembly 4, collects and analyzes the hull data, obtains the test data, and performs online verification of the test data through the data verification module, thereby reducing the production activities required for the quality inspection of ship products, ensuring that the quality of ship products meets the design standards, and avoiding unnecessary energy loss during navigation due to substandard hull data.

[0021] The first assembly part 1 includes an outer arc plate 101 and a slide groove 102 provided on the inner side of the outer arc plate 101, and the slide groove 102 is used to connect the main track assembly 3. The second assembly part 2 includes an outer arc plate 201, and one side of the outer arc plate 201 is hinged to one side of the outer arc plate 101. The cross-sections of the outer arc plate 101 and the outer arc plate 201 are both semicircular. When the assembly part is in an open state, the first assembly part 1 and the second assembly part 2 are open, and the outer arc plate 101 and the outer arc plate 201 form a W-shaped structure; when the assembly part is in a closed state, the first assembly part 1 and the second assembly part 2 are closed, and the outer arc plate 101 and the outer arc plate 201 form a cylindrical structure, and the cylindrical structure has openings only at both ends.

[0022] When testing the pipeline in the hull, the first assembly 1 and the second assembly 2 are in a closed state, and the pipeline to be tested is surrounded by the above-mentioned cylindrical structure. The track adjustment member 7 is a linear driving component, through which the main track assembly 3 can be driven to move along the length direction of the first assembly 1, so that the main track assembly 3 can be docked with any auxiliary track assembly 4 to form a circular track, and the position adjustment member 6 can drive the distance meter 5 to move along the circular track. During the pipeline inspection test, the main track assembly 3 first docks with one of the auxiliary track assemblies 4 to form a circular track. Under the action of the position adjustment member 6, the distance meter 5 moves along the circular track and performs circular path multi-point distance measurement around the pipeline. After the distance meter 5 rotates around the pipeline once, the position adjustment member 6 returns from the auxiliary track assembly 4 to the main track assembly 3 and resets, and then the main track assembly 3 is docked with the next auxiliary track assembly 4 through the track adjustment member 7, and the circular path multi-point distance measurement is performed again. Repeating the above process can perform multiple circular path multi-point distance measurements at different length positions of the pipeline. The distance measurement results are analyzed by the data processing module to obtain the size detection test data of the pipeline. The distance meter 5 is preferably a laser distance meter. This detection method can also be applied to the detection of columnar hull structures such as columns, masts, cables, etc. in the hull.

[0023] When testing non-columnar structures in the hull, such as testing the bottom, hull, bow, stern, cabin passage, cargo hold passage and other structures, the first assembly 1 and the second assembly 2 are opened, the position adjustment member 6 remains stationary relative to the main track assembly 3, and the track adjustment member 7 drives the main track assembly 3 to move linearly, and the main track assembly 3 drives the position adjustment member 6 and the rangefinder 5 thereon to move linearly, and the linear path multi-point distance measurement can be performed on the structure to be measured, and the distance measurement results are analyzed by the data processing module to obtain the size detection test data of other structures to be measured. The data measurement module can adapt to various types of hull structures, improve the accuracy of test data, and make the hull structure detection process more convenient.

[0024] Specifically, Figure 2-5As shown, the main track assembly 3 includes an inner arc plate 301, and a plurality of protruding teeth 302 are fixedly arranged on one side of the inner arc plate 301, and the plurality of protruding teeth 302 are arranged in a semicircular arc shape on the inner side of the inner arc plate 301, and two semicircular arc tracks 303 are fixedly arranged on the other side of the inner arc plate 301. A slider S is fixedly arranged on the outer side of the inner arc plate 301, and the slider S is slidably matched with the slide groove 102 on the outer arc plate 101, and a groove 103 is provided in the middle of the outer arc plate 101 along its length direction. The track adjustment member 7 is preferably a screw motor, and the groove 103 is used to accommodate the screw of the screw motor. A nut pair P is also fixedly arranged on the outer side of the inner arc plate 301, and the nut pair P is embedded in the groove 103 and is threadedly connected with the screw of the screw motor. The structure of the auxiliary track assembly 4 is the same as that of the main track assembly 3, and no more details are given. The position adjusting member 6 comprises a mounting frame 601 slidably connected to the semicircular arc track 303 , a gear 602 rotatably arranged at one end of the mounting frame 601 , and a power source for driving the gear 602 to rotate, and the gear 602 is meshed with the convex tooth 302 .

[0025] The power source includes a motor 603 fixed on the mounting frame 601, and a worm gear transmission mechanism arranged between the motor 603 and the gear 602. The worm gear transmission mechanism can play a locking role and a deceleration role. A roller 1 604 is provided on one side of the bottom of the mounting frame 601, and a roller 2 605 is provided on the other side of the bottom of the mounting frame 601. The roller 1 604 is in rolling cooperation with the semicircular arc track 303, and the roller 2 605 is attached to the inner side of the inner arc plate 301. The mounting frame 601 is composed of an assembly plate 1, an assembly plate 2 and an assembly plate 3. The assembly plate 2 is fixed on the side wall of the assembly plate 1 in the width direction, and the assembly plate 3 is fixed on the side wall of the assembly plate 1 in the length direction. The assembly plate 1 is provided with a through mounting hole 606, and the mounting hole 606 is used to assemble the worm wheel of the worm gear transmission mechanism. The assembly plate 2 is used to fix the rangefinder 5, and the assembly plate 3 is used to fix the motor 603. Roller 1 604 is disposed on assembly plate 2 and is used to limit the mounting frame 601 so that the position adjustment member 6 is close to the main track assembly 3 . Roller 2 605 is disposed on assembly plate 3 and is used to support the mounting frame 601 .

[0026] When the first assembly 1 and the second assembly 2 are in the closed state, the two semicircular arc tracks 303 on the main track assembly 3 and the other two semicircular arc tracks on the auxiliary track assembly 4 form two annular tracks, and the inner arc plate 301 and a group of convex teeth 302 on the main track assembly 3 and another inner arc plate and another group of convex teeth on the auxiliary track assembly 4 form a gear ring structure. The motor 603 drives the gear 602 to rotate through the worm gear transmission mechanism, and through the meshing of the gear 602 and the gear ring structure, the mounting frame 601 and the rangefinder 5 thereon are driven to move in a circular motion, so that the rangefinder 5 can complete the multi-point distance measurement of the circular path.

[0027] Furthermore, if Figure 6 and Figure 7As shown, the data metering module also includes a walking component 8, a lifting component 9 fixed on the top of the walking component 8, a rotating driving member 10 arranged on the top of the lifting component 9, and a mounting plate 11 arranged at the output end of the rotating driving member 10, and the first assembly 1 is fixed on one side of the mounting plate 11. The walking component 8 is preferably a power trolley, the lifting component 9 is preferably a folding lifting platform with a top plate on the top, and the rotating driving member 10 is preferably a reduction motor with a locking function. A linear driving member 12 is provided on the top of the lifting component 9, and the linear driving member 12 is used to drive the rotating driving member 10 to slide on the lifting component 9. The linear driving member 12 is preferably an electric push rod. Specifically, the outer arc plate 101 of the first assembly 1 is fixed on the mounting plate 11 through a group of brackets, and a group of positioning plates 202 are provided on the outer side of the outer arc plate 201, and another group of brackets corresponding to the positioning plates 202 are provided on the mounting plate 11. When the assembly is opened, the positioning plates 202 are fixedly connected to the corresponding brackets by threaded fasteners to keep the assembly open. A slot is provided at the top of the lifting component 9 , which passes through one end of the top of the lifting component 9 , and a support plate 14 is embedded in the slot. The support plate 14 is used to provide support for the first assembly part 1 during non-detection tests.

[0028] Before conducting a formal inspection test on the pipeline, the data metering module can also adjust the angle of the cylindrical structure composed of the outer arc plate 101 and the outer arc plate 201 to improve the parallelism between the axis of the cylindrical structure and the axis of the pipeline. During the adjustment process, the track adjustment component 7 drives the main track component 3 to dock with the auxiliary track components 4 at both ends of the cylindrical structure in turn, and the distance meter 5 performs two circular path multi-point distance measurements accordingly. The data processing module calculates the position information of the center of both sides of the pipeline according to the test results of the distance meter 5, and obtains the axis angle and position information of the pipeline to be tested according to the position information. Afterwards, the walking component 8 adjusts the position and posture of the above-mentioned cylindrical structure according to the axis angle and position information of the pipeline to be tested, in cooperation with the lifting component 9 and the rotating drive component 10, so that the cylindrical structure has a good parallelism with the pipeline to be tested. Through the above adjustment, the verticality of the distance meter 5 and the pipeline to be tested is better, which can improve the distance measurement accuracy, thereby improving the accuracy of the test data. In addition, please refer to Figure 7 When the pipeline to be tested is inclined at a vertical or nearly vertical angle, the linear drive member 12 can be used to drive the mounting plate 11 to move toward the outside of the lifting assembly 9 to ensure that the pipeline to be tested can enter the cylindrical structure.

[0029] The data metering module also includes a linear track assembly 13, which includes two straight tracks 1301 corresponding to roller 1 604, two pads 1302 corresponding to roller 2 605, and a rack 1303 corresponding to the gear 602. The straight tracks 1301, the pads 1302 and the rack 1303 are all fixedly arranged on the top of the lifting assembly 9. When the structure to be measured is above the data metering module, the position adjustment member 6 can also be removed from the main track assembly 3 and installed on the linear track assembly 13. When removing the position adjustment member 6, the assembly is kept in the open state, and the motor 603 moves the mounting frame 601 to the lower end of the semicircular arc track 303 through the worm gear transmission mechanism and the gear 602. When the gear 602 is located at the lower end of the inner arc plate 301, the meshing state between it and the convex tooth 302 is released, and the position adjustment member 6 can be removed from the main track assembly 3. After that, roller 1 604 is placed in the straight track 1301, so that the gear 602 contacts and meshes with the end of the rack 1303, and the worm wheel of the worm gear transmission mechanism is between the two pads 1302. The motor 603 is started again, and the position adjustment member 6 can be installed on the linear track assembly 13. The motor 603 cooperates with the worm gear transmission mechanism to drive the gear 602 to rotate, and the gear 602 is meshed with the rack 1303, so that the position adjustment member 6 and the rangefinder 5 thereon can move linearly, so as to perform linear path multi-point distance measurement on the structure to be measured. In addition, in some other embodiments, the position adjustment member 6 can also be installed on other supporting structures to perform detection tests on other structures of the hull. In some other embodiments, the data acquisition module of the data metering module also includes a diesel engine emission data acquisition component, which is preferably a NOx sensor for detecting the nitrogen oxide content emitted by the diesel engine of the ship product. The nitrogen oxide content is analyzed by the data processing module in conjunction with the NOx sensor to obtain the diesel engine emission data. The data metering module sends the test data consisting of the diesel engine emission data and the hull data to the data metering module of the classification society through the data sharing platform for data verification.

[0030] In addition, a camera 15 is provided on the mounting frame 601, and the camera 15 is used to collect image information while the rangefinder 5 collects hull data. The camera 15 and the rangefinder 5 work synchronously, and the data processing module sends the test data and the image information collected by the camera 15 to the data verification module through the data sharing platform, and the surveyor can further analyze the hull data in combination with the test data and the image information. And because the data collection process of the camera 15 and the rangefinder 5 is synchronous, the image information is related to the test data, and the surveyor can compare the image information with the test data, which can avoid the test personnel from mistransmitting data.

[0031] The data sharing platform in this embodiment is preferably an SCBC platform, which is used to provide data services to manufacturers and classification societies. The platform is a data sharing platform for the ship and marine engineering industry based on blockchain. The data verification module includes a data review module, a data verification module, a certificate issuance module and an interface call module 2. The data metering module in the manufacturer calls the API interface of the data sharing platform through the interface call module 1, interacts with the data sharing platform, and sends data to the data verification module in the classification society; the data verification module in the classification society calls the API interface of the data sharing platform through the interface call module 2, interacts with the data sharing platform, and sends data to the data metering module in the manufacturer.

[0032] In the process of the manufacturer applying for verification and certification from the classification society, the data measurement module obtains the standard dictionary of ship products through the data sharing platform. The data sharing platform sends the standard dictionary to the classification society for dictionary review. The data review module reviews the standard dictionary. After the review is passed, the data sharing platform sends the standard dictionary of ship products to the data measurement module of the manufacturer. The manufacturer's personnel edit the standard dictionary to form configuration data, and send the configuration data to the data sharing platform, and initiate an inspection application. After receiving the inspection application, the data sharing platform sends the configuration data to the data verification module. The data verification module reviews the configuration data through the data review module. After the data review is completed, the test data verification stage and the certification stage are carried out. When there are omissions in the configuration data, manual acceptance is required, and the data review is terminated after the manual acceptance is passed; when there are no omissions in the configuration data, the certificate can be issued quickly, that is, the data review can be terminated directly without manual acceptance, and the subsequent test data verification stage and certification stage can be carried out.

[0033] During the verification phase of the test data, the data measurement module collects the hull data through the data acquisition module, and performs measurement and analysis on the data through the data processing module. After the analysis is completed, the test data is obtained. After the manufacturer obtains the test data, it sends the test data to the data verification module of the classification society through the data sharing platform. The test data is verified by the data verification module. After the verification is qualified, it enters the certification phase. Conversely, feedback information is provided to the data measurement module to enable the manufacturer to resubmit the test data until the verification is qualified.

[0034] The data storage module pre-stores the parts data and industrial data when producing parts. In the certification stage, the data measurement module sends the parts data and industrial data to the certificate issuance module of the data verification module through the data sharing platform. The certificate issuance module conducts a document review of the parts data and industrial data, and compiles the certificate after the review is passed. After the certificate review is passed, a visa is added to the certificate, and the certificate with the visa is stored in the blockchain and the data measurement module of the manufacturer through the data sharing platform. This enables online data measurement verification and certification of digital ship products. In addition, the manufacturer can also initiate a change request to the data sharing platform through the data measurement module. Changes can be made before the certificate is issued, but changes are not allowed after the certificate is issued.

[0035] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
