Description

RFID Tag Attaching Device, RFID Reader, and Transporter including the RFID Reader for Ship Block Management}

The present invention relates to an RFID tag attachment device, an RFID reader device for ship block management, and a transporter for ship block transport, wherein the identification number of a ship block is applied by applying RFID technology for efficient ship block management in a shipyard ship construction site. The present invention relates to an apparatus for attaching an RFID tag to a ship block for identification purposes.

The size of ship block is gradually increasing in order to limit the space of dock in shipyard yard and shorten the ship construction period. In order to perform a series of tasks such as assembly, painting, and design of a ship block in a drying process, a transporter is moved to a corresponding factory or branch by moving a ship block. At this time, the shape in which the ship block is placed in accordance with the operation can be loaded by changing the position up, down, left and right. In this case, the site operator may be placed in a location where the work schedule attached to the ship block is not easily visible.

Conventional ship block identification method was made by the operator directly checks the work management table attached to the lower end of the ship block with the naked eye at the yard site. This method requires the operator to go directly to the work management table attached to the ship block and check it, and there is a problem of misreading the contents of the written work management table, and if the top, bottom, left and right sides of the ship block change according to the immediately preceding work process. The problem is that the work order attached by tape or bond is removed and put back into the desired position (eg, bottom). The larger the size of the ship block, the greater the difficulty of the worker finding the work management table attached to the ship block.

In addition, when the RFID tag is directly attached to the ship block at the site performing the process, the transporter may enter the surface where the RFID tag is not attached according to the conditions of the ship block loading site. To prevent this, RFID tags must be attached to each of the four sides of the ship block, which can lead to an increase in process management costs. In addition, when the shape in which the ship block is placed is changed up, down, left, and right, the position of the RFID tag may be outside the RFID reader antenna coverage, so that the ship block identification number may not be confirmed.

The present invention is to solve the above problems, the ship block management for the ship block to ensure that the identification number of the ship block to easily read the RFID tag even if the transporter enters any direction on the site where the ship block is loaded It is an object of the present invention to provide an RFID tag attachment device.

The height of the support 11 may be such that the transporter 30 can travel therebetween, or the RFID tag attachment device 20 in which a portion of the RFID reader device 40 installed on the transporter 30 is attached to the lower surface of the ship block. ) Can be raised high enough to proceed to the lower part of the ship block.

Meanwhile, the RFID reader device 40 includes an RFID reader 41 and an RFID reader antenna 42 and is installed in a part of the transporter 30. As will be described in more detail later, the RFID reader 41 filters the data collected through the RFID reader antenna 42, processes it, and delivers the data to a remote server where the operator is located, or delivers the data to the driver's terminal server. To be able to view the management information of the ship block.

In addition, the RFID reader antenna 42 is formed to be rotatable so as to freely adjust the direction of orientation of the antenna to maintain a high recognition rate of the RFID at all times.

In addition, the RFID reader device 40 may further include a beep generation request device 43 to be described later in more detail. The beep generation request device 43 transmits a beep generation request signal to the beep generation unit 103 included in the RFID tag attachment device 20 attached to the selection block 10.

Meanwhile, the transporter 30 is formed to include a transporter upper plate 31 and a driver 32 including a power unit, a wheel unit, a driving unit (not shown), and the like, which allow the transporter to move. The transporter upper plate 31 may be formed in part or in all of iron so that the RFID reader antenna 42 may be attached by a magnet.

In addition, the RFID tag attaching device 20 includes an RFID tag and a beep generator 103.

The tag recognition rate can be increased.

In the RFID tag attachment device according to the embodiment of the present invention, at least one metal piece 106 may be attached to the lower end of the RFID tag holder 101, thereby preventing the holder from moving around in the wind. In addition, the RFID tag holder 101 may include a space for accommodating the ship block work management table, through which the operator can write or modify the work content to report the work management table with the naked eye at the shipyard site Conventional methods of identifying ship blocks can also be applied. Through this, the recognition of the RFID reader and the tag by various various environments can be prevented from malfunctioning due to a malfunction and the ship block identification becomes impossible.

On the other hand, the RFID tag holder 101 may be formed of a vinyl material of the luminous, through which it is not leaked by snow, rain, can be identified at night or at a distance. Further, the longitudinal length of the RFID tag holder 101 may be shorter than the height of the support 20 supporting the ship block 10, however long.

If the RFID reader device 40 of the transporter 30 fails to check management information of a ship block that is out of line of sight (LOS: Line of Sight), the beep generation request device of the RFID reader device 40 ( 43 transmits a beep sound generation request signal, and the beep sound generation unit 103 mounted in the RFID tag holder 101 receives the beep sound generation request signal and generates a beep sound. This beep makes it easy to locate the RFID tag on the ship block.

Hereinafter, a transporter 30 carrying a ship block according to another embodiment of the present invention will be described.
