DETAILED DESCRIPTION

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] Figure 1 ,2 , 3, 4, 5, 6, 7 show three views of the intelligent monitoring system and related sectional enlarged views. The intelligent monitoring system used in the shipyard includes a longitudinal drive device 2 arranged on the longitudinal beam 1, a transverse drive device 4 arranged on the transverse beam 3, a top monitoring device, a plurality of bottom monitoring devices 7 and an underground navigation magnetic nail 8, and the longitudinal shells 2a of the two longitudinal drive devices 2 located on the longitudinal beam 1 are fixedly connected at both ends of the transverse beam 3.

[0028] The longitudinal beam 1 is provided with a longitudinal track 1a and a longitudinal rack 2d, the longitudinal drive gear 2c driven by the longitudinal motor 2g through the longitudinal reducer 2f and the longitudinal shaft 2e is meshed with the longitudinal rack 2d, and the longitudinal roller 2b is located in the slide groove of the longitudinal track 1a. The transverse beam 3 is provided with a transverse track 3a and a transverse rack 4d, the transverse drive gear 4c driven by the transverse motor 4g through the transverse reducer 4f and the transverse shaft 4e is meshed with the transverse rack 4d, and the transverse roller 4b is located in the slide groove of the transverse track 3a.

[0029] The top monitoring device includes an upper lifting device 5 and an upper industrial camera 6. The upper lead screw 5c of the upper lifting device 5 is connected to the upper industrial camera 6. The hollow connecting rod 5b is fixed to the end of the horizontal driving device 4 through the connecting plate 5a. The top monitoring device is connected to the computer processing terminal through network communication technology. The upper industrial camera 6 on the top monitoring device takes pictures and transmits them to the computer processing terminal through network communication technology. The image recognition technology is used to judge to achieve intelligent monitoring.

[0030] The lower end of the hollow connecting rod 5b of the upper lifting device 5 is connected to the upper screw 5e matched with the upper lead screw 5c through the rolling bearing 5d, and the outer periphery of the upper screw 5e is provided with teeth meshing with the upper gear 5f driven by the upper stepping motor 5h. The upper stepping motor 5h drives the upper screw 5e to rotate through the upper gear 5f. Because the hollow connecting rod 5b is a hollow tube, the upper lead screw 5c will extend into or out of the hollow tube under the drive of the upper screw nut 5e, so as to realize the lifting of the upper industrial camera 6.

[0031] The underground navigation magnetic nails 8 are laid in the ground foundation, and the bottom monitoring device 7 transmits the position information in real time through the magnetic navigation sensor 7n and controls the movement of the bottom monitoring device 7 through the computer processing terminal.

[0032] Figure 8 , 9 The bottom monitoring device 7 has a front view and a top view. The base of the bottom monitoring device 7 is connected to a lower platform plate 7b through a lower lifting device, and a lower industrial camera 7a and an infrared sensing device 7c are arranged on the lower platform plate 7b. The base is provided with a magnetic navigation sensor 7n and a Mecanum wheel 7k driven by a travel motor 7h.

[0033] A hollow vertical tube is provided on the base of the lower lifting device, and the upper end of the hollow vertical tube is connected to the lower screw 7e matched with the lower screw 7d through a rolling bearing, and the outer periphery of the lower screw 7e is provided with teeth meshing with the lower gear 7f driven by the lower stepping motor 7g. The lower stepping motor 7g drives the lower screw 7e to rotate through the lower gear 7f. Because the hollow vertical tube is a hollow tube, the lower screw 7d will extend into or out of the hollow tube under the drive of the lower screw nut 7e, so as to realize the lifting and lowering of the lower industrial camera 7a.

[0034] The four Mecanum wheels 7k on the bottom monitoring device 7 are controlled by a computer control terminal to drive the corresponding travel motor 7h to rotate forward, reverse and supply power, thereby realizing the omnidirectional movement of the bottom monitoring device 7.

[0035] The bottom monitoring device 7 is connected to the computer processing terminal through network communication technology. The lower industrial camera 7a on the bottom monitoring device 7 takes pictures and transmits them to the computer processing terminal through network communication technology. The image recognition technology is used to judge to achieve intelligent monitoring.

[0036] Fig.10 The work flow chart of this monitoring system is shown. In the working process of this system, the bottom monitoring equipment and the top monitoring equipment take pictures of the environment required by the workshop and collect images, and save them in the database of the computer processing terminal through network communication technology. The corresponding data processing is carried out through the preset program in the database to complete the relevant engineering projects and feed the data back to the database.

[0037] Fig.11 The schematic diagram of the database architecture of this monitoring system is shown. The data of the system during the working process and the completed engineering projects are stored in the database. The database presets the management end and the working end, and the permissions are determined by the account. The management end has the functions of modifying user permissions and information, engineering permissions and information, and log maintenance. The working end intends to use functions such as progress monitoring, weight estimation, and weld monitoring. Through data import, enter the corresponding function area according to certain permissions, and analyze and process the collected image data through the preset program to achieve the corresponding engineering purpose.

[0038] Example 1: Shipbuilding progress monitoring

[0039] During the shipbuilding process, the computer processing terminal controls multiple bottom detection equipment to move along the pre-laid underground magnetic nail route and controls the lower industrial camera to take photos of the bottom of the shipyard workshop according to the preset frequency. At the same time, the infrared sensing equipment is used for collision detection and collision avoidance during the movement. The Mecanum wheel is driven to move in all directions by controlling the forward and reverse rotation of the travel motor, and the lifting and lowering of the lower lifting device are controlled to adjust the image acquisition range of the lower industrial camera. At the same time, the computer control terminal controls the coordinated operation of the top detection equipment, controls the horizontal drive device and the longitudinal drive device to drive the corresponding crossbeam and longitudinal beam and control the operation of the upper lifting device, changes the position of the upper industrial camera in the monitoring system, and performs corresponding image acquisition. The upper and lower industrial cameras are used to record the construction progress of the intermediate products of the ship, such as assembly and segmentation, analyze the pictures taken, use image processing technology to determine the work progress, coordinate the communication between departments, and thus improve the transparency of the construction process.

[0040] Example 2: Estimation of Ship Steel Weight

[0041] In the process of shipbuilding, this monitoring system is preset in the steel material stacking workshop, and multiple bottom detection devices are used in the control box of the computer processing terminal to shoot the image of the stacked steel materials. The three-dimensional size of the regular steel plate is obtained by using image recognition technology, and the corresponding calculation is performed to solve the weight of the stacked steel materials. By presetting the top detection equipment in the processing workshop, the graphics of the steel plate residue after each processing procedure are photographed, and the weight of the steel plate residue is estimated by image processing technology. Through the storage of the computer processing terminal, the corresponding data is provided for the subsequent estimation of the weight center of gravity of the ship.
