RFID (Radio Frequency Identification) allows data to be exchanged using wireless communication in a certain frequency band, and stores various types of information in a tag and transmits the stored information to the reader by radio waves transmitted from a separate reader.

Accordingly, RFID tags storing various types of information are attached to various objects as shown in the following patent documents, and information stored in the RFID tags is read through a reader, etc. to manage various objects and obtain information.

On the other hand, in the construction site, the PC (Precast Concrete) method, in which pillars, beams, and slabs of the building are manufactured in advance at the factory and assembled at the site, is used. In the process, the need for management using RFID tags is increasing because they are not properly managed.

However, factories and sites where PC members are manufactured and installed can be easily exposed to contaminants such as dust, so even if RFID is installed, the recognition rate may be lowered. It is difficult to install RFID tags on PC members made of concrete. Cases can arise.

Hereinafter, exemplary embodiments of a waterproof and dustproof RFID tag, a PC member including the same, and a PC management system using the same according to the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, when it is determined that a detailed description of a known function or configuration may unnecessarily obscure the subject matter of the present invention, a detailed description thereof will be omitted. Throughout the specification, when a part "includes" a certain component, it means that other components may be further included, and other components are not excluded unless specifically stated to the contrary. Terms such as "... unit" and "... module" mean a unit that processes at least one function or operation, which may be implemented by hardware or software or a combination of hardware and software.

When a waterproof and dustproof RFID tag according to an embodiment of the present invention is described with reference to FIGS. 1 to 6, the RFID tag 1 is formed of a steel plate, and the lower bracket 11 on which the tag member 15 is mounted. )and; A cover housing 12 coupled to an upper portion of the lower bracket 11 to cover and seal the tag member 15; Fixed blades 14 protruding from both sides of the lower bracket 11 to couple the RFID tag 1 to another structure; A coupling part 13 for coupling the lower bracket 11 and the cover housing 12; And a tag member 15 that stores various types of information and is accommodated in a closed space between the lower bracket 11 and the cover housing 12.

The RFID tag 1 according to the present invention accommodates the tag member 15 in which various types of information are stored in an enclosed space to block contamination by dust, dust, water, etc. of the tag member 15. The RFID tag 1 may be used in various places such as factories and construction sites, but in particular, as described later, concrete is poured while being attached to the formwork P to be manufactured in a state accommodated in the PC member 3. And, through this, it is possible to manage the PC member 3, so that the information stored in the tag member 15 can be accurately read only when the tag member 15 is prevented from being contaminated. Accordingly, the RFID tag 1 is effectively waterproof and dustproof through a unique coupling structure and sealing structure.

The lower bracket 11 is formed of a steel plate having a certain area so that the tag member 15 is seated thereon. Further, the cover housing 12 is in close contact with and coupled to the upper portion of the lower bracket 11 to seal the tag member 15, and the coupling portion 13 at the edge of the lower bracket 11 is coupled. In addition, fixing blades 14 are formed on both sides of the lower bracket 11 so that the RFID tag 1 can be attached to a separate attachment. In particular, the lower bracket 11 includes a protruding end 111 protruding upward along the circumference as shown in FIG. 3, and the cover housing 12 is accommodated in the protruding end 111 do. Accordingly, the cover housing 12 accommodating the tag member 15 in the sealed space is accommodated inside the protruding end 111 to minimize contact with the outside, thereby reducing the inflow of contaminants such as dust.

The cover housing 12 is configured to accommodate the tag member 15 mounted on the lower bracket 11 by being coupled from the upper side of the lower bracket 11 in a sealed space. Make it close to the lower bracket 11 from the inside of (111). The cover housing 12 forms a certain space to accommodate the tag member 15 seated on the lower bracket 11, and the outer contact end 121 moves downward as shown in FIG. 3 along the circumference. It protrudes and makes it in close contact with the lower bracket 11. In addition, the recessed groove 123 is formed to be recessed upwardly inside the outer contact end 121 so that the sealing agent 124 is injected into the space between the lower bracket 11 and hardened. In particular, an inner separation end 122 spaced apart from the lower bracket 11 by a predetermined height may be formed inside the recessed groove 123. The sealing agent 124 flows through the space between the inner separation end 122 and the lower bracket 11. If only the outer contact end 121 is formed and the sealing agent 124 is applied to the inside thereof, the sealing agent 124 is not fixed and thus a portion that cannot block contaminants occurs, and depending on the use, the sealing agent 124 ) Is eliminated and pollutants are introduced. In addition, when only the recessed groove 123 is formed inside the outer contact end 121, it is difficult to insert the sealing agent into the recessed groove 123, and the recessed groove 123 will cause the sealing agent 124 to be excessively injected. In this case, rather, the sealing agent 124 flows between the cover housing 12 and the lower bracket 11, thereby causing a problem that the gap between the cover housing 12 and the lower bracket 11 is widened. Therefore, the present invention primarily prevents the inflow of contaminants by contacting the outer contact end 121 and the lower bracket 11, while the sealing agent 124 is hardened inside the cover housing 12 The space is blocked, and the sealing agent 124 introduced into the recessed groove 123 can flow through the space between the inner separating end 122 and the lower bracket 11, thereby sealing the recessed groove 123 It is possible to prevent the cover housing 12 and the lower bracket 11 from being separated by overflowing the sealing agent 124 of the recessed groove 123 while being faithfully filled by the 124. The sealing agent 124 may be formed of gel-like silicon, etc., and is introduced into the recessed groove 123 to harden.
