The present invention relates to a ceiling surface finishing material, and more particularly, to a ceiling surface finishing material having an interior lighting function as well as a built-in RFID for navigation of a mobile robot.

Recently, as part of building an automation system for a home, office, or factory, an RFID (Radio frequency ID) tag is embedded in a flooring material or a barcode is printed on the flooring material and the location information from the mobile robot is used. Techniques are being developed to enable this autonomous operation.

For example, as shown in Figure 1, when installing the flooring material 2 is installed on the floor of the home or office a plurality of RFID tags (1a, 1b, 1c) at regular intervals, the mobile robot 3 The installed RF reader 4 receives information about the absolute coordinates from the RFID tags 1a, 1b, and 1c, and calculates the relative coordinates, the moving direction, the moving distance, and the like from the absolute coordinates to autonomously move.

However, the above proposal to embed the RFID in the flooring has the following practical problems.

In other words, when embedding the RFID tag inside the flooring material, excessive force is applied to the flooring material when carrying or installing the flooring material with the built-in RFID, and the embedded RFID circuit may be damaged, especially rolled and sold. In case of cerium, the problem of RFID damage may be more serious.

In addition, while transporting a heavy object in the office or at home there is a problem that the corner portion of the object is severely exposed to the floor material is exposed to the risk of damaging the RFID. In the case of flooring, even if some of the RFID is damaged, the entire flooring material has to be removed and the damaged RFID needs to be replaced.

In addition, when the RFID is to be installed on a specific layer of the flooring having a multi-layer structure, the adhesiveness between the flooring material and the RFID tag may be inferior, and the thickness of the flooring material may be uneven due to the RFID.

The present invention has been proposed to solve the above problems, and an object of the present invention is to provide a ceiling finishing material so that an RFID tag that provides location information for autonomous movement of a mobile robot can be installed on the ceiling surface.

In addition, it aims to provide a convenience of life by adding a lighting function to the ceiling finish.

The ceiling surface finishing material according to the present invention for achieving the above object, the adhesive layer and the back layer is sequentially stacked on the back surface of the decorative sheet for the finish of the ceiling surface, the active RFID tag having its own power source is installed on the front surface of the decorative sheet. It is characterized by.

In this case, the RFID tag is adhered to the front surface of the decor sheet, and then coated with a transparent resin layer thereon, to be fixed to the front surface of the decor sheet.

On the other hand, the RFID tag is surrounded by a protective housing together with a human body sensor connected to a printed circuit board using the power of the RFID tag and a light emitting diode lit by a signal from the human body sensor. Can be installed on the front of the.

At this time, the protective housing is preferably to be detachably installed on the front of the decorative sheet for ease of installation and easy replacement during product defects.

In general, the RFID system can be classified into an inductively coupled method and an electromagnetic wave method according to a wireless connection method. The mutual induction method uses a coil antenna and all energy required to operate an IC chip of a tag is Passive type supplied from the reader and used for short distance (within 1m), and electromagnetic wave type is active for medium to long distance (3 ~ 10m) including additional battery for driving IC chip by wireless connection with each other using high frequency antenna. Used.

The RFID tag used in the present invention is installed on the ceiling surface finishing material, and the distance from the bottom surface is usually about 3 to 4M, it is preferable to use an active RFID tag of the electromagnetic wave type.

Deco sheet is a product in which polyvinyl chloride (Polyvinyl Chloride (PVC)) or polypropylene (Polypropylene: PP) is laminated with a printing layer and wear-resistant and scratch-resistant transparent film on general wood. It is glued directly or to other ceiling finishes such as wood and gypsum board.

Hereinafter, with reference to the accompanying drawings looks at with respect to the ceiling surface finish according to a preferred embodiment of the present invention.

As shown in FIG. 2, the finishing material 10 is constructed on the ceiling surface 1, and the front surface of the finishing material 10 includes a plurality of built-in RFID tags (not shown) for navigation of the mobile robot 3. Protective housing 20 is installed. The protective housings 20 are orthogonally arranged in the longitudinal direction along the ceiling surface, and the RFID tag embedded in each protective housing 20 provides absolute coordinates to the mobile robot that autonomously moves on the bottom surface 2.

Figure 3 shows an example of the ceiling surface finish bar, as can be seen in Figure 3, the ceiling surface finish material for the finishing of the ceiling surface 10 and the protective housing detachably coupled to the front of the finish material. It consists of 20.

Finishing material 10 has a structure in which the adhesive layer 12 and the back layer 13 are sequentially stacked on the back surface of the decorative sheet 11 for finishing the ceiling surface. As the decor sheet 11, an olefin decor sheet which has been recently increased in use can be used. At the time of construction of the finishing material 10, the surface layer 13 is peeled off and then attached to the ceiling surface or another ceiling surface finishing material using the adhesive layer 12. To facilitate peeling of the back layer 13, a handle portion 14 protrudes from the edge of the back layer 13.

The protective housing 20 is detachably installed on the front surface of the finishing material 10, that is, the decor sheet 11, and may be installed one per finishing material when the finishing material is a small size, and a plurality of protective housings when the finishing material is large. 20 may be installed.

At this time, the front surface of the decorative sheet 11 is fixed to the fixing member 30 having a side cross-sectional shape of '⊂' to detachably couple the protective housing 20 to the decorative sheet 11, the protective housing ( 20, the fitting groove 21 having a side cross-sectional shape of '⊃' is formed so that the front end of the fixing member 30 can be fitted. Protrusions 22 and 31 are formed at the distal end of the fixing member 30 and the distal end of the fitting groove 21, respectively. When the distal end of the fixing member is inserted into the fitting groove 21 of the protective housing, The protective housing 20 is fixed to the fixing member 30 by locking.

With reference to Figures 3 and 4 will be described with respect to the electrical device installed in the protective housing (20, 20a).

The protective housing 20 is connected to an active RFID tag 40 having its own power source 44 and a printed circuit board 50 which jointly uses the power source 44 of the RFID tag 40. A human body sensor 52 and a light emitting diode 51 which are lit by the signal from the human body sensor are provided.

The RFID tag 40 is composed of a microchip 41 for controlling the operation of the tag, a high frequency antenna 42 and a power source 44 connected thereto. At this time, the RFID tag is provided with an on / off switch 43 for forcibly stopping the operation of the RFID tag on the electric line. Furniture or desk is installed in the lower part of the RFID so that the navigation can be turned off when the navigation of the mobile robot is unnecessary.

The light emitting diode 51 and the human body monitoring sensor 52 connected to the printed circuit board 50 are configured to receive power for the operation from the power 44 of the RFID tag. The power consumption 44 needs to be installed to be replaceable since power consumption is greater than when only the RFID tag is operated. In addition, an electric line connecting the printed circuit board 50 and the power supply 44 is provided with an on / off switch 53 for forcibly stopping the operation of the light emitting diodes 51.

The human body sensor 52 typically uses a sensor installed in a staircase or a passage, and when the human body sensor 52 detects a person when lighting is dark, the light emitting diode 51 is turned on in the printed circuit board 50. Let's go.

Figure 5 shows another example of the ceiling surface finish bar, looking at this, the configuration of the finishing material in which the adhesive layer 12 and the back layer 13 are sequentially laminated on the back surface of the decor sheet 11, the protective housing 20a The configuration of the electrical devices 40, 51, and 52 installed therein is the same as the above example, but the method of coupling the protective housing 20a to the decor sheet 11 is different.

In this example, but the fixing member (30a) is installed on the decor sheet 11, the protective housing (20a) is screwed by a bolt (B) rather than being fitted to the fixing member. Of course, a hole for insertion of the bolt B is formed in the fixing member 30a, and a fixing member inserting groove 21a is formed in the protective housing 20a at which the fixing member 30a is fastened.

6 shows another example of the ceiling finish, as shown in FIG. 6, the RFID tag 60 is attached to the front surface of the decor sheet 11 and then covered with a transparent or opaque resin layer 61. Can be fixed. Of course, only the RFID tag 60 may be used in a state of being simply adhered to the front surface of the decor sheet 11.

At this time, since an electrical device such as a sensor or a light emitting diode is not installed together, the thickness of the resin layer 61 covering the RFID tag 60 is not so thick. The configuration of the back layer of the decor sheet 11 is the same as the previous case.

According to the ceiling surface finishing material having the structure as described above, the RFID tag providing the position information for autonomous movement of the mobile robot can be easily installed on the ceiling surface, the conventional problem by installing the RFID tag on the floor Can be solved.

In addition, the lighting function is added to the ceiling finish, so that the consumer can sense the location even in the dark. Such lighting may be used for mood lighting.
