Description

Transbay stanby steel plate management system for cutting}

The present invention relates to a transbay cutting standby steel management system, and more particularly, to the effective steel management of the transbay cutting standby steel management system interlocked with the steel loading management system, pretreatment system, cutting system, ERP system.

After pretreatment of steel, according to the cutting schedule, a waiting place, that is, a stockyard, that is stacked and managed to put steel in the cutting site is required. This space is commonly referred to as a transbay in a shipyard.

In general, as shown in Figure 1, the steel transported through the steel storage management system and pre-treatment plant of the steel storage is piled in the transbay as the impending cutting input is required for the filing operation to bind the steels of the same property, It is important to establish an efficient loading plan to place the steel close to the site where the steel is applied.

A technology related to such steel loading management system is disclosed in Korean Unexamined Patent Publication No. 2010-0131701 (A real-time steel management system and method using a magnetic crane and a conveyor).

2, the crane moving unit 110 for lifting and unloading the steel by using magnetic power; A conveyor moving part 120 for moving the steel material unloaded from the crane moving part 110 to a specific position by using a conveyor; An input device that receives the information of the steel from the outside and inputs or receives location information for moving the steel from the user; And storing the steel information received from the input device 130 in a steel database, or storing the steel moving position information received from the crane moving unit 110 in a file database, or transferring the information from the conveyor moving unit 110. Provides a configuration comprising a; integrated database (DB) server 140 for storing and managing the received steel moving position information in the conveyor database.

In addition, the movement of steel materials between piles in the transbay is very frequent due to the cutting and inputting of cutting stations (in-house cutting boards and external cutting boards), which can be changed from time to time according to the production process status.

In particular, a lot of worker hours are put into management to manage the steel history such as steel received through conveyors, steel pile piled up, and steel input to internal and external cutting sites.

In order to manage the steel piles in the transbay, the work manager establishes daily daily loading plans for the steel piles close to the cutting site to be put in accordance with the steel line, block, cutting series and cutting schedule. Exchange the necessary information by wire or mail to share the current steel file status.

The steel worker, along with the crane operator, manages all the steel entering and leaving the transbay and the residue after cutting to check the work history of the transbay steel pile and the temporary steel pile at the cutting site, and the efficient transbay steel management performed by these workers. Will greatly affect the cutting schedule.

The steel worker writes the transfer contents by hand every time the steel transfer works and updates the stock loading status at the same time before the work shift.

Therefore, the wrong steel loading information can be input by mistake of the operator, and the time required to update the steel loading status manually is excessively generated.

In addition, the post-department departments that require the cutting-waiting steel status of Transbay are inquiring by wire or e-mail every time to check the stock loading status.

Therefore, when the steel transfer is made incorrectly due to human error between workers, the task of finding and correcting the misplaced steel after a certain time inevitably occurs.

The work manager compares the pretreatment plan with the cutting schedule and the steel information of the ERP system to establish the transbay load plan, and determines the location of the pile pile of incoming steel, and also computerizes most of the time in preparing and delivering the established work plan. Is not happening.

Therefore, excessive judgment time for optimal placement is put into practice and practical inefficient work planning and management is being made.

In addition, the marking company marks the location of the pile pile previously planned for the steel by hand so that the crane worker can check it every time the pretreated steel is introduced into the transbay.

When the destination marking is completed, frequent human errors occur in moving the pile pile by the crane worker, causing problems such as steel damage and loss.

In addition, when the steel is shipped, the export worker manually writes the shipping information to the previously printed outing area, and checks the steel weight and quantity directly at the outgoing place by using the calculator to adjust the trailer capacity (about 25 tons). I am working.

In particular, in the case of wide (large) steels, if a single sheet is included, an extra amount must be paid when getting on the trailer. Due to limitations, the optimal placement of wide steels is not possible.

In addition, in order to effectively insert the steel to be cut into the cutting site, the steel inputted according to the ship's construction schedule needs to be stored in one transbay steel pile.

However, because the steel is loaded in transbay in the order of receiving the pretreated steel, it is often piled randomly in several steel piles.

In addition, even though the steel pile pile is managed by establishing a reasonable steel pile work plan, considerable judgment and working time are required in the process of collecting and arranging the steel due to the urgent steel request from the cutting site and the change of the cutting schedule.

And during the steel pile cleanup, the crane can not perform the receiving work at the same time can adversely affect the productivity of the associated post-process.

In general, steel load management system processes data through a wireless communication network in a series of processes, the crane does not directly process the state data received from the controller. In other words, if it is different from the system's wireless communication protocol TCP / IP, the access is directly restricted to the server-side local DB on the crane side.

Therefore, the data of all cranes are received and collected by the server through an arbitrary wireless communication network, and each steel event is calculated and driven by interlocking the data with the local DB of the server. As a result, the amount of communication handled by the wireless communication module increases, and wireless communication overload frequently occurs, causing a failure in server collecting crane data.

In addition, when the server side performs data processing operation that tracks the crane status using all the crane data, if the data throughput is large, system down occurs due to the system load.

Therefore, in order to solve the inefficiency of the transbay operation and the problems of the existing system, an integrated management system that can effectively plan and operate the transbay standby steel management process after pretreatment is required.

In order to solve the above problems, the steel loading management system, the pretreatment system, the cutting system, and the ERP system is connected to the transbay cutting steel management system equipped with a path calculation module for storing and arranging steels in the transbay storage yard. It provides a transbay cut-waiting steel management system that indicates the shortest working path that can efficiently and quickly reduce work time.

In addition, the TransBay server distributes the operation program that provides steel loading plan, steel file cleanup plan, transbay steel file inquiry function to related departments, and receives and receives steel deposit work and export steel reservation management function. A program is used to manage the steel entering and leaving Transbay.

In addition, the transbay cutting steel management system using a magnetic crane to move the exported steel to the trailer, grasp the starting signal of the trailer to extract the steel data and timing to be transported and the data of the transbay cutting steel management system Link and extract the extracted data with the base.

In addition, the access of the trailer is installed at least one of the image sensor, proximity sensor or weight sensor in the trailer area to check the access of the trailer.
