Description

{Real-time Process Monitoring System using Block Image}

The present invention relates to a real-time process monitoring system using a block image, and more particularly, to a system and method for real-time process monitoring using a block image, more specifically, And to a system for monitoring a portion requiring correction of a layout plan or input of additional manpower by using the obtained result.

Generally, a large shipyard is equipped with several docks, and a plurality of blocks different in ship type and linear type are simultaneously being produced, and each ship is divided into blocks of a predetermined size. The divided blocks are enlarged by assembling process, design process, coating process, and mounting process, and each process area is scattered all over the yard because the required equipment is different.

In order to control the amount of goods to be shipped and the amount of goods to be delivered between distributed lines, the administrator must know the progress of the block production process in advance. In this case, external influences such as weather, It is a major factor in causing disruption to progress.

The general management method is to record the block production process of the field directly by the manager at least once a day, and the form to be used differs according to the management purpose. FIG. 1 is an example of a status table that displays and manages the position and progress of an assembly block in a turning factory.

Among the above-mentioned processes, the area where the arrangement of blocks and the production schedule are most strictly managed is the assembling process inside the factory (see FIG. 2). Since it is directly related to the productivity where the steel and the member that have been cut and machined in the limited working area are placed and how long to assemble the block, the placement plan is made about one month different from the other process and the progress is checked and managed. The design process and coating process are relatively less important because of the shorter working period than the assembly process.

The ship factory where the assembly process is performed is divided into a flat block area having a planar abacus and a curved block area having an angular abacus. In the case of a flat block, it moves sequentially along the conveyor, so it is possible to estimate the progress by grasping the relative position. However, in the case of the curved block, since the abacus is raised on the pin jig using a crane, There is no sex. In the assembling process, it is common to set the abacus of the block in accordance with a previously set layout plan, and when the block is completed, it is generally taken out through a passage and moved to a post-process using a transporter.

However, there are several problems here.

1. Visual Inspection and Handling Status Report

The schedule and the layout plan of the block to be put in accordance with the middle class are prepared by the manager in charge for the next two rounds (approx. 10-15 days for one round), and it changes organically according to the production results. As a result, the managers must check and adjust the progress of the block production process in the field from time to time. However, the on-site confirmation work that takes more than 5 hours per day to perform the production instruction and the layout plan is a burden to the managers.

Actually, each manager is responsible for 1 to 1.5 bases, and the progress of the block production process arranged on the whole bases is checked again, and the status table (see FIG. 1) is created and distributed by hand. Although there is a process of building a block repeatedly, there is a difference between the process of confirming the progress and the process of creating the status table. Thus, there is a time difference between the production time and the confirmation time of the block, It is difficult to do.

2. Schedule changes based on administrator experience

In the current management system, production scheduling, layout planning, and progress are delivered to the manager, but nothing is systematically related. It is difficult to expect a certain adjustment result because it is purely the responsibility of the manager to identify and adjust the associations among the elements that exist as separate data, and the calculations that accompany them depend on experience.

3. Deployment planning vs. block shape interlocking constraint

Although there is a block shape necessary to make the layout plan according to the production schedule, it is not linked with the production style, and the manager prepares the shape corresponding to the ratio directly and arranges it on the plaque of the plaid pattern 1). As the layout plan and management status are all produced in separate document format (EXCEL), excessive time is spent.

4. Limitations of analysis due to individual file management

In the case of a handwritten document, the document file is the minimum management unit because it does not use a specialized storage structure such as a database, and thus it is difficult to have an association between the produced status tables as a result. If a block list is required to be imported / exported on a monthly basis, it is necessary to take a considerable amount of time to obtain the required results because the management system as described above compiles each document file.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

The present invention relates to a real-time process monitoring system using a block image, more specifically, a process of automatically monitoring the progress of a block production process, In addition, it provides a system that monitors the parts needed to revise the layout plan or to input additional manpower using the obtained results.

The application of the present invention is mainly a block drying in a shipyard. The reason for this is that in the case of building blocks in the shipyard, different products have to be produced each time according to the shipowner's requirements, and the operation is continued for a long time in a fixed position. The longer the work period, the wider the work area, and the greater the number of products produced, the greater the impact of the layout plan and its utilization. Conversely, in the case of the line production system, since the same product is produced on the conveyor, the production amount becomes a main concern rather than the monitoring of the batch status or the progress, and thus it is not suitable to be applied to the present invention.

FIG. 3 shows the construction of a real-time process monitoring system using a block image according to the present invention.

The present invention comprises an image acquisition system 10, a video management system 20, a design support system 30, a data extraction system 40, a database 50, and a server system 60. Hereinafter, functions and functions of the constituent elements of the present invention will be described in detail.

Image acquisition system

The image collection system 10 collects the image of the block arranged on the surface of the table in real time and transmits it to the image management system 20.

More specifically, the image capturing system 10 includes an image capturing unit 11 that converts a video image of a block input in real time via a camera lens into a digital signal, An image storing unit 12 for temporarily storing a video image of a block converted into an image stored in the image storing unit 12 and an image storing unit 12 for storing the image of the block temporarily stored in the image storing unit 12, And a transfer unit 13.

Video management system

The image management system 20 receives and stores the image image transmitted from the image collection system 10 every time. Assuming that the image acquisition system 10 (more specifically, the image storage 12) is a small capacity storage, the image management system 20 may be referred to as a large capacity storage.

Since the image management system 20 has not only storage of image images but also management functions, it is possible to inquire, delete, and update image images through the image management system 20. Also, the block ID, the image image collection date and time may be managed through the image management system 20.

Meanwhile, the video management system 20 has a function of selectively transmitting a desired video image to a server system 60 that performs a main operation. The server system 60 compares the video image received from the video management system 20 with the design model transmitted from the data extraction system 40 to determine the progress of the block production process In this case, the closer the video image is to the design model, the higher the degree of progress, and vice versa.

Design Support System

The design support system 30 stores the design model of the block. Here, the design model refers to an object having shape information and attribute information of the completed block, and the design model is a structure model for the server system 60 to understand the progress of the block production process .

The design support system 30 is a part of a CAD system used in designing products in various industries, and in the present invention, indicates a shipyard CAD system as a target industry. The design support system 30 stores a plurality of model types / linear design models, and has its own database so that a plurality of users can simultaneously access and work on them. There are Tribon, Aveva Marine, and GS CAD as representative design support systems 30 used in the shipyard. Although there are various types and data types to be stored for each of these design support systems 30, It should be equipped with a function to retrieve data such as drawings and members.

Data extraction system

The data extraction system 40 selectively extracts only the shape information and attribute information of the design model necessary for grasping the progress in the server system 60 from the design support system 30 and transmits the extracted shape information and attribute information to the server system 60, In this case, the data extraction system 40 simplifies and processes the shape information of the design model as much as possible in order to increase the visualization and operation speed in the server system 60.

Generally, in order to increase the accuracy of the curved surface in the CAD system, the data capacity increases considerably. In general, since the design data processed by the server per operation is several tens per designation, the shape information of the design model is simplified, . On the other hand, in order to efficiently extract the data required by the server system 60 for performing the main operation, it is necessary to provide an interface type data extraction system 40.

Database

The database 50 stores and manages surface information, block information, and layout plan information. For this purpose, the database 50 stores the result data of the server system 60 and some of the data extracted by the design support system 30 . The database 50 is made up of four types of information tables such as a plan management table 51, a configuration management table 52, a progress management table 53, and an assembly member management table 54.

The plan management table 51 has attributes such as the block ID and the block name, the date of receipt, the date of the release, the placement position, and the placement angle of the block, and stores information for comparing the progress plan and the placement plan (See Fig. 4). The shape management table 52 stores the block ID, the file name including the shape information of the block, and the attributes such as the storage path, for the main purpose of storing the shape information of the block outputted in the form specified by the data extraction system 40 (See Fig. 5). The progress degree management table 53 stores information on which block is currently disposed and the progress thereof based on the progress degree obtained by the server system 60. The progress degree management table 53 includes a block ID, Location, placement planning progress, block building progress, update time, and the like (see FIG. 6). Finally, the assembly member management table 54 stores the block lower member information for generating the design model image used in the block progress comparison. The block member ID management table 54 includes a block ID and a lower member ID, a member level (Level) And the like (see FIG. 7).

Server system

The server system 60 in which the main operation is performed compares the image of the block received from the image management system 20 with the design model of the block received from the data extraction system 40 to calculate the progress of the block production process, Monitor the status of the deployment and coordinate the deployment plan. The server system 60 includes a progress degree inference unit 61, a base placement status monitoring unit 62, and a base placement plan adjustment unit 63.

The progress degree inference unit 61 calculates the progress of the block production process. For this, the progress inferring unit 61 compares the image image received from the image management system 20 with the design model transmitted from the data extraction system 40 (the design model is a 3D image while the image image is a projected 2D image (See FIG. 8), and the progress of the block manufacturing process that has been performed so far is calculated by dividing the members input into the block production into a predetermined unit (see FIG. 8) .

In this case, the progress inferring unit 61 calculates the progress of the image as the closer to the design model, and the lower the progress of the image, the more the progress image is calculated. More specifically, And the value calculated through the ratio of the members stored in the database 50 is updated to the progress degree.

The placement status monitoring unit 62 displays the position and progress of the block through the monitoring interface. As shown in FIG. 9, the block shape is automatically arranged on the base and the progress degree calculated by the progress degree inference unit 61 Display. The main function of the base placement monitoring unit 62 is to display a delayed or fluctuating operation as compared with the layout plan, which indicates a part where the user (manager) should adjust the schedule or the input staff. In the embodiment of FIG. 9, the layout layout is divided into three levels of normal, delay, and warning on the monitoring interface, and is displayed in different colors.

The layout layout plan adjustment unit 63 adjusts the layout plan of the blocks in operation, and this function of the layout layout plan adjustment unit 63 can also be utilized for creating a schedule before the user (manager) arranges the blocks . The base placement plan adjustment unit 63 generates schedule information to be compared with monitoring, and adjusts the schedule information when a problem occurs.

As described above, according to the present invention, it is possible to automatically grasp the progress of a block manufacturing process that is performed by a front end factory, and to modify a block layout plan or to monitor a portion requiring additional manpower in real time .

It will be apparent to those skilled in the art that various modifications, substitutions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. will be.
