TECHNICAL FIELD [0001] The present invention relates to a steel material information management system,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel material information management technology, and more particularly to a crane position measuring device for measuring a moving distance to a crane for moving a steel plate by loading a steel plate. A steel plate movement information input device installed in the cabin of the crane and receiving movement information about the steel plate; And a steel material cumulative information generating device for generating cumulative information for the steel plate on the basis of the movement distance to the crane and the movement information about the steel plate so that the worker can generate reliable cumulative information through the position tracking of the crane The present invention relates to a steel material information management system.

Steels entering the loading dock are loaded and unloaded by the trailer. The operator sets the bays in the loading bay in consideration of various conditions such as the stocking condition of each bay and the daily work load, The steel material is stacked and managed. The worker divides the yard inside the yard into files, and manages the inventory, such as stacking / sorting the steel to a specified file number. The steel is put into sorting, stacking and pretreatment considering the same block used and the date of the assembly process. At this time, the sorting operation takes a great deal of weight. In the past, the overhead crane operator identifies and moves the file number of the destination to which the steel material should move using a paintbrush for each steel material to be sorted by the worker (signal number).

At this time, a dangerous situation may occur in which a serious accident may occur due to the crane magnet due to carelessness of the crane driver. In addition, the number of signals must be found in the file for the steel to be sorted, and details of the steel are marked on the upper side of the steel, which makes it difficult to sort the steel.

In addition, if the crane driver is visually restricted due to environmental influences such as weather (rain) and nighttime, the steel classification is repeated several times, or the file number display status is damaged due to rain, Are often occurring. In this case, the file number should be confirmed by another worker and informed to the magnetic crane operator through the radio, which causes problems such as increase of work time and manual sorting of steel.

The following prior art provides related technology.

Korean Patent Laid-Open Publication No. 10-2012-0133595 relates to a method of providing a steel material racking plan in real time, and more particularly, to a method of providing a steel material racking providing method, A work instruction information providing step (S10) of outputting work instruction information to a screen and providing work instruction information; The crane position information, the lifting weight information, the lifting and dropping state information are detected and output to the screen, and the work instruction sheet (S20) for judging the completion status of the job on the server; If the task indicated in the work instruction sheet is completed in the work state determination process (S20), completion of the task is indicated in the work instruction sheet, and the completion information on the completion of the task is transmitted to the management server (S30) of updating the steel material information to be updated by a program. The present invention also relates to a steel material information providing method for providing a steel material racking plan in real time.

In the prior art including the prior art, it is difficult for a worker to trust the position and order of the steel plate by determining the order and position of the steel plate based on the movement information of the steel plate itself. More specifically, steel plates for shipbuilding, which are generally shipped from a steel mill and arrived at a shipyard, are sorted and placed according to production schedule before being put into the site through pretreatment and cutting processes. Here, when a steel sheet having an average size of 4000 mm * 1500 mm * 80 mm is stacked, an average of 100 to 200 sheets are stacked per file, making it difficult to match the position and order. In other words, there is an urgent need for a technology that accurately grasps the position and order of the current steel sheet in terms of work efficiency.
