DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, with reference to the drawings, specific details for implementing a parking position indicating tag according to the present invention will be described in detail with reference to embodiments.

The parking position indicating tag 1 according to the present invention displays the parking position information of the vehicle parked in the parking lot on the tag so that the user can easily confirm the parking position of the vehicle. Receives the parking position information from the parking terminal 2 installed at the same place as the wall surface and displays the parking position on the tag 1.

1, a tag 1 for indicating a parking position includes a tag main body 10, an NFC module 20, and an EPD film 30. As shown in Fig.

The tag main body 10 is small in size so that it can be carried by a user, and is small in size to be connected to a ring of a car key, for example.

The NFC module 20 is mounted inside the tag body 10 and performs near field wireless communication. That is, the parking position information transmitted from the parking terminal 2 installed in the parking area of the parking lot P and equipped with the transceiver module is wirelessly received, and the received parking position information is provided to the EPD 30.

Near Field Communication (NFC) is a non-contact communication technology that uses the frequency band of 13.56 MHz as one of the electronic tag technologies in short-range wireless communication. Because it is a technology for wireless communication with a short distance, it is attracting attention as a communication technology on the basis of the next generation because its communication is short and its security is relatively superior and its price is low. It can be used both reading and writing data. It is used for various services such as traffic and ticket fees, payment at shops, locks for access control, and everyday life.

For example, as shown in FIG. 2, if the tag 1 in which the NFC module 20 with the NFC technology applied is brought close to the column parking terminal 2 installed in the column of the parking area P, Without any connection procedure, they can be wirelessly connected to each other and receive signals from the transceiver module.

3, the NFC module 20 includes an NFC antenna 21 for receiving parking position information from the transceiver module of the parking terminal 2, An NFC chip 22 for controlling an EPD driver IC and an EPD film 30 for displaying an image such as a character or an image related to parking position information on the EPD film 30. [ And an EPD driving IC 23 for controlling the EPD driving IC 23.

The EPD film 30 is installed on the outer surface of the tag main body 10 and is formed in a film form and displays parking position information provided from the NFC module 20 to the outside to check parking position information do.

EPD is an electrophoretic display that realizes white and black particles on a substrate by moving them through an electrical principle. In recent years, EPD has been used as an electronic paper (e-paper) concept Lt; / RTI > Here, electrophoresis refers to a phenomenon in which colloidal particles move toward one of the electrodes when a DC voltage is applied by placing an electrode in a colloid solution. This technique is mainly applied to a display for protein or DNA separation in biochemistry . These EPDs are famous for E-ink and SiPix, and they are manufactured in capsule type (Microcapsules type) and cup type (Microcups type) respectively.

For example, referring to FIG. 4A, the operation principle of the EPD of the capsule type of E-ink will be described. A top transparent electrode is provided on the top, a bottom electrode is provided on the bottom, Microcapsules are located between the metal electrodes, and the inside of the microcapsule is filled with a clear fluid. Inside the transparent solution, white particles charged with positive charge (+) and minus -) There are many black particles charged by charge. When an electric field is applied to the upper transparent electrode and the lower metal electrode, the white particles and the black particles respectively move to the electrode having polarity opposite to the charged electric charge, thereby displaying an image such as a character or an image.

Although not shown separately, the cup type EPD of SiPix has the same basic components and operating principle as that of E-ink, but the particle is a single color and only the charge of one kind of positive (+) or negative (- And it is in the form of a cup, not a capsule, and it is characterized by being injected with R, G, B color liquid in the inside of the microcup to be colored.

As shown in FIG. 4B, in the EPD film 30, particles having respective charges are dispersed in a fluid, and when an electric field is applied to the transmission mode, particles are dispersed according to the direction and intensity of the applied electric field. And the characters related to the parking position information are displayed on the EPD film 30. After the voltage is shut off, the transmission mode is maintained for a maximum of several days due to the memory effect of the EPD material itself. The display can be continued without consuming the battery, and the parking position can be checked even in the case of short-term parking.

The NFC module 20 and the EPD film 30 may be made of a flexible material such as soft synthetic resin, synthetic rubber, silicone, or the like, The dead zone of the screen according to the viewing angle is eliminated and the viewing angle with respect to the parking position information displayed on the EPD film 30 is increased to facilitate the confirmation.

As a result, the parking position indicating tag 1 according to the present invention is easy to carry, has no power consumption, and always displays the parking position on the EPD film after communication at a close distance from the parking terminal, It is possible to confirm easily, and there is a residual image for a maximum of several days, so that it is possible to confirm the parking position even in the short-term parking.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
