The used slippers are recovered, undergone with the erasure of the display simultaneously with the disinfection and provided again. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention includes a non-contact IC that can exchange data in a wireless tag (RFID tag) communication system, and a rewrite card that can be written and erased, and an electronic paper display function, so that the user's name can be changed each time. It is automatically displayed on a display tag attached to the hooking portion so that the slipper user himself / herself can check the slipper being used. In addition, the display window relates to a system in which simple communication and advertisement can be made by entering from a personal computer at the same time as the room number and period of use. Especially in places where an unspecified number of people use slippers, such as inns, hotels, and hospitals, it is necessary to make the slipper display name and user name exactly match. The present invention relates to a system that automatically displays the name on the slipper after confirming the identity and the correspondence between the slipper and the use slipper through the IC card.

  There are many business establishments that prohibit slipping, replace them, and provide slippers, etc. at places where an unspecified number of visitors come and go, such as hotels, inns, hospitals (clinics), and offices. On the other hand, the importance of preventive measures has been screamed more than ever for hospital-acquired infections caused by tuberculosis and MRSA, imported infections such as AIDS and malaria, and new infections such as O157 and SARS. As a measure to prevent infection with bacteria and viruses, various guidelines such as guidelines for the actions of medical personnel and environmental maintenance standards for equipment and appliances have been set in hospitals, but almost all footwear and slippers are used for footwear and slippers. It can be said that ringworm bacteria are attached.

  As a Japanese custom, footwear is often used separately for outdoor use and indoor use. In ordinary households, the lifestyle is shifted from a life on a tatami mat with bare feet or socks and socks to a board between which a slipper is used as a footwear. And in each home, the footwear used by each individual is often specified. The outerwear is further divided and used for toilets and customers. On the other hand, in hotels, inns, hospitals, and business establishments that do not like dust, there are many places where people use shoes, and slippers, hooks, and sandals are generally used.

  The management of the outerwear used by such an unspecified large number of people is at most a number management by giving a number, or after passing through the UV irradiation box, it is provided to the customer. Users are rarely identified when used by an unspecified majority. For this reason, there are many cases where hygiene management is not easy. Many users use slippers provided with awareness of the dangers of athlete's foot infections, especially when they take off slippers once they are removed, especially in a large inn in a ryokan. It is only. Some terrible places offer deformed or damaged items, making visitors feel uncomfortable.

Recently, each person's awareness of the prevention of athlete's foot has been gradually improved, and the number of visitors has been increased by disinfecting his shoes and slippers and providing a service to fill in the name of the visitor on the disinfected slippers. It will also lead to improvement of business results at the office.

  The problem to be solved is that management of slippers used by a large number of unspecified people such as hotels, inns, hospitals (clinics), offices, etc. is in large quantities, especially in ryokan to banquet halls and bathhouses In most cases, footwear is used interchangeably. In many cases, the user is switched in this way, which complicates hygiene management and cannot escape from anxiety of infection such as ringworm.

  In order to solve this problem, it is possible to identify the user by identifying the footwear and thereby scatter, prevent the user from being replaced, and at the same time perform the sterilization treatment that is generally performed, After the disinfection by irradiating with sun rays or artificial ultraviolet rays, etc., the number of footwear and hygiene are managed by writing and providing the name of the new user. Develop sanitary footwear that can be managed by a combination of photocatalytic sterilization, RFID tag (wireless tag) communication technology, and rewrite card and electronic paper display technology so that facility managers are not bothered by these tasks as much as possible. did. That is, among various data-related technologies that support logistic, the RFID technology that can transmit / receive / read / write data provided to the IC chip wirelessly is applied.

  By restricting the number of footwear users by automatically writing their names and the bactericidal action of the photocatalyst, they can be freed from anxiety about infections such as ringworm and manage and provide sanitary footwear. As a result, the need to establish repeat customers and increase the number of visitors can be realized. In addition, since this technique can manage the number of slippers, the application can be expanded to the distribution management of various articles.

  The slippers and the like according to the present invention are used in places where an unspecified number of people come and go, such as hotels, inns, hospitals and offices. An RFID tag display window is provided on the hooked portion of the upper surface of the slipper or the like so that the user's name is written. Then, an IC chip for storing display erasure and rewriting data, an IC for receiving reader / writer, IC card key data and a microwave as a power source, and transmitting IC chip data are provided. A battery can be provided as necessary as a power source for transmission and reception and display.

  First, in order to identify slippers users, inns and hotels often make reservations, so make a list of names along with the date and time of stay, period, and room number, and store them on your computer. It can be kept. The same procedure is performed at the reception desk at the front desk. An IC card key to which this data is input is created and handed over to the visitors as a room key, one for each person after confirming the identity. Normally, guests are able to identify individuals because they carry their room IC card keys when they are out or on the move. Some people go out with the IC card key in the room when several people are in the same room, so this IC card key is brought in close proximity to the surface of the slipper tag worn by each person and personal data is read into the slipper. You can also. Since the closer the distance to be approached, the more accurate data can be exchanged. Normally, 1 meter or less is an appropriate distance. However, if the receivable distance is increased too much, there is a risk of interference in a crowded place. 5 to 0.1 meters is desirable. If the slipper is powered at this stage, the IC data of the card key can be read reliably and the name can be displayed on the RFID tag of the slipper. However, since the same name can be displayed on a number of slippers with a single card key and malfunctions due to battery consumption can be considered, it is desirable to have a battery-less structure that can use microwaves from the reader / writer as a power source. In other words, each person usually carries an IC card key one by one, and the reader / writer first reads the IC card key data and compares it with the data on the personal computer. A system is used in which waves are transmitted as a power source and writing is displayed. Simultaneously with the carrying of the IC card key, the data of the user himself / herself is taken into the IC chip of the slipper, and the slipper corresponds to each person 1: 1. In hospitals and the like, there are many cases in which a medical examination ticket is used in advance. Therefore, by holding an IC chip in the medical examination ticket, it is possible to identify the person himself and take correspondence between the person and the slipper. For visitors who do not have an examination ticket or room card key, a replacement card will be issued at the reception. By embedding an IC chip in a tag for carrying a user of a management tag such as changed shoes and assigning a unique symbol or number, it is possible to have a 1: 1 correspondence between individuals and slippers simultaneously with shoe management. . In this case, it is possible to manage sufficiently by displaying symbols and numbers instead of names. In this way, it is possible to identify slippers used by hospital visitors and short-time visitors.

  As a device necessary to display a name or the like without much trouble on the display window of such a slipper, first, a personal computer that manages the entire system is used as a transmitting device. Data such as a reservation list is created in advance on a personal computer. A reader / writer with an antenna for communicating with the slipper is connected to this personal computer by wire or wirelessly. When the reader / writer receives the user data stored in the IC of the slipper, the reader / writer transmits a command for displaying the name and the like on the RFID tag of the slipper when the data matches the data in the personal computer. At this time, if the slipper user carries the IC card key, the reader / writer can read the data of the IC card key and the IC data of the slipper at the same time, so that the write command radio wave can be transmitted more reliably. Since the completion of writing can be confirmed at the same time, the command radio wave can be transmitted each time until the completion of writing is confirmed. The slipper side includes an antenna for receiving radio waves, an IC chip for storing data, and an RFID tag for displaying the received data. As a display method, a leuco rewrite card or electronic paper is used. These display media can display the data of the IC chip without requiring a power source.

  As the radio wave conductive medium method, a microwave method capable of long-distance communication is desirable, and a readable / writable type is adopted as an access method for stored data. As for the power supply system, a battery may be attached to the slipper, but it is desirable that the battery be supplied without a microwave antenna. Since the distance from the reader / writer to the radio wave is about 5m, for example, inns and hotels often provide slippers for entrances or rooms, but when people send and receive data at such places, many people When it is crowded, there is a problem of causing interference and malfunction. In addition, installation of a reader / writer in each room and installation of an antenna network in the entire building increases the equipment cost. Therefore, the reader / writer must be installed in the hall with a passage, stairs or entrance to the bathing area where customers must pass, and when it passes through it, slipper data is read and when it matches the contents of the PC, a command radio wave for displaying the name is sent. To display. This display operation is set up so that it can be performed only once and the completion of the display can be confirmed, and the display is continued during the stay period.

  In other words, when a person carrying an IC card key with personal data read in advance or wearing a slipper with personal data read passes through the reader / writer's antenna signal range, the reader / writer queries the slipper data contents. Read the slipper data and issue a display command when the name is not displayed. The slipper once displayed is programmed so that it cannot be rewritten so as to maintain the display state until the use date and time ends. If the person carrying the IC card key uses a new pair of slippers, the name will be displayed, and it will be checked by displaying that it is the second pair, or it will not be displayed from the third pair It is also possible to do. In the case of a temporary user such as a one-day person, number management is simply performed. The slippers that have been used are cleared at the collection place, sterilization box, etc., and prepared for the next use after sterilization.

To clear the display automatically, there is a method to clear the display at the same time as the trial person's stay period ends by waiting for the clock function with the calendar on the slipper, but it is not preferable because the slipper becomes expensive and causes failure. . When the slipper collection place is the entrance, when the used slipper is once collected and stored in the sterilization box or the like, a deletion signal is transmitted from the reader / writer to erase the display of the plurality of slippers at once.
When slippers are changed in each room, if an antenna network is installed in each room or a reader / writer is installed in each room, erasing can be performed in each room, but the equipment cost may increase. In addition, the display can be erased at the time of room making with a remote controller capable of transmitting only an erasure signal. However, when erasing is performed indoors, a sterilization operation is separately performed. Therefore, when slippers are provided in each room, the slippers after use are collected and replaced with slippers that have been disinfected and cleared the display as part of room making. The collected slippers may be sterilized and the display erased by a sterilization box installed where the reader / writer can reach radio waves.

  By limiting the number of users by the above method, this slipper prevents the spread of infection by bacteria, etc., and pre-catalysts, antibacterial agents, etc. Using a slipper made of a treated antibacterial material, or using a product obtained by spraying a photocatalyst or the like on a ready-made slipper, washing is performed after use, or sterilization is performed by sunlight or ultraviolet irradiation treatment. Therefore, the user can use slippers and other tops without feeling uncomfortable. In the following, the structure and method of use of the slipper with tag according to the present invention will be described with reference to the drawings and the flow chart.

  FIG. 1 shows an RFID (Radio Frequency Identification) wireless identification tag 4 having an IC chip 10 and a radio wave receiving antenna 11 combined with a rewrite card 5-1 and electronic paper 5-2 (IC tag, IC label). The slipper 3 is attached to the upper surface of the hooking portion.

  The rewrite card of FIG. 1 is a non-contact IC rewrite, and there are a thermal rewrite card and a leuco rewrite card, but a leuco rewrite card having a larger display area and a black printing color is desirable than a thermal cloudy rewrite. The electronic paper is a non-contact IC card with a display and uses electronic paper technology (scattering / transmission type liquid crystal). Since it is driven by a signal (radio wave) from the reader / writer, a battery is unnecessary and control by a built-in driver IC is also possible.

  Compared to the consumption speed of slippers incorporating RFID tags and rewrite cards (or electronic paper), the RFID tags and rewrite cards and electronic paper can be used for a relatively long time. It is desirable to attach an insertion bag 15 made of transparent vinyl to the upper surface of the hook portion and insert it into this.

  A cross-sectional view of the name display part of the RFID tag is shown in the center right part of FIG. The RFID tag 4 that combines the antenna 11 and the IC chip 10 has a structure in which a rewrite card or electronic paper is attached to the upper surface of the RFID tag 4 with an adhesive. A PET film 12 is laid under the RFID tag main body, and the lower surface is peeled off with a pressure-sensitive adhesive and attached to a target location. When inserting the RFID tag into a plastic bag or the like attached to the target location, use it with the release paper attached.

This slipper is made of a material that has been antibacterial processed with chemicals or a photocatalyst, or a slipper that is photocatalyzed on the entire upper surface that touches light and skin. The fabric of the slipper is made of a material that is mixed with cotton linen that has been treated with an antibacterial agent in advance, or the catalyst is made of TiO ₂ that has a little catalytic activity in order to avoid degradation and degradation of the optical slipper body and resin binder part. Spray.

  FIG. 2 shows a basic configuration of a communication apparatus for displaying the name of the user on the display unit of the slipper. Reference numeral 6 denotes a management personal computer for inputting, storing, and processing data corresponding to the name of the customer in advance. A plurality of reader / writers 7 are connected to the personal computer in a wired or wireless manner. In order to prevent erroneous connection, it is desirable to connect with a cable. The reader / writer incorporates a controller and an antenna so that the stored data of the IC card key and the stored data of the slipper RFID tag can be read and the display command to the slipper can be transmitted. However, these communication means are: (1) When the antenna in the RFID tag receives radio waves from the reader / writer, (2) Electromagnetic induction occurs due to resonance action, and electromotive force is generated (3) IC chip in the RFID tag is activated Then, the data in the chip is converted into a signal. (4) When a signal is transmitted from the antenna from the card side, (5) The signal sent from the antenna of the reader / writer is caught (6) Data is sent to the personal computer (data processing device) via the controller (7 ) Data processing such as recognition is performed on the software side. In such verification, when the IC card key and the slipper are close to each other, that is, even if the person wearing the slipper carries the IC card key, the reader / writer can read the data of the IC card key. Therefore, it is possible to command writing more accurately.

  FIG. 3 shows a configuration diagram of a system necessary for writing / erasing to / from the RFID tag slipper in carrying out the present invention. In order to identify the person who uses the slippers of the present invention, a card key of a room used by each person who has visited or entered or a hospital or the like uses an examination ticket. An IC chip that stores data such as name, room number, stay date / time, and identification number is embedded in the card key and the examination ticket. There are personal computers that convert personal data into data and a plurality of reader / writers connected to the personal computer with cables. The reader / writer carries the IC card key, reads the IC card data of the customer wearing the slipper, compares it with the data in the personal computer, identifies the person, and writes the slipper to the IC chip and RFID of the slipper. Write command radio waves and power required for writing. However, multiple reader / writers will be installed at places where people in the vicinity of entrances and exits such as branch points, stairs, banquet halls, and bathhouses in the hallway. The user can use the same slippers for his / her name displayed in a place such as a banquet hall or a bathhouse where it is easy to change. The slipper display is maintained during the customer's stay, and when the customer leaves, the slipper is collected and sterilized, and for example, a reader / writer installed near the storage box while being stored in the ultraviolet irradiation box The display erase signal is sent from to clear the slipper display.

  Next, when using the slipper provided with the RFID tag, the flow of the slipper will be described, and the display method of the user's name and the like and the flow until erasure will be described. FIG. 4 is a flow chart of the use cycle of the slipper with RFID tag. First of all, those who wish to stay at a hotel inn, a doctor's office or a hospital, or those who wish to have a medical examination, apply for a reservation in advance by telephone. The receptionist judges whether or not to accept, and if it can be accepted, the application data is entered into the personal computer at the office or front desk with the name, room number, stay date and other data, and at the same time, the IC card key is issued. The key is used to unlock the key of the assigned guest room door. If you have a doctor's office or hospital, this is your examination ticket. When the customer enters the room, the IC card key is handed over after confirming the identity of the guest, and slippers that do not have their name written in the guest room are usually provided at the inn at the inn and at the hotel. The customer usually wears a card key when moving inside the building with slippers, so if the customer wears an IC card key and an unnamed slipper and enters the reader / writer installation location within 5 meters, the reader First, data is transmitted from the card key in response to the radio wave from the writer. The reader / writer collates the customer data with the data of the personal computer, transmits the data to the IC of the RFID tag of the slipper and simultaneously writes the data. The user's name, room number, etc. are displayed on the slipper while moving, so if you use the slipper again after taking it off, such as a bathhouse or banquet hall, the customer will continue to use the slipper with his name I can do it. When entering, customers take off slippers at each room or front door, change to shoes, return the IC card key, check out, and go out. The IC card key is used again after clearing. The slippers that remain on the display after use are collected, sterilized, and provided again to the next customer. However, when you return to the hall once again, if you have a system where you can change shoes and slippers in your room, or change to shoes at the front door and store shoes in place using shoe management tags Except for, slippers take off at the front door. In this case, it is necessary to collect once and provide a new non-display slipper to the re-entry person. However, since the customer carries the IC card key, the name can be displayed on the slipper when passing the place where the reader / writer is installed.

  FIG. 5 shows the flow of slipper recovery and sterilization treatment and display after use. First, all used slippers left in the storage place such as slippers removed at the front door and the predetermined shoe box at the front door are collected, checked for form, and stored in an ultraviolet irradiation box for sterilization. At the same time, a display erasure signal is transmitted by the reader / writer to clear the slipper display. On the other hand, the slippers provided in the room collect the slipper displaying the name of the previous customer at the time of room making and replace it with a new slipper.

  FIG. 6 shows a principle diagram of a slipper RFID tag writing method. This is an example of a microwave system that can take the longest transmission distance. The reader / writer is equipped with a controller and a transmitting / receiving antenna and is connected to a personal computer with a cable. The antenna is also used for supplying microwave power. First, the reader / writer reads the transmission signal from the IC card key in the room and compares it with the data of the personal computer via the controller. When the registered contents match and the name is not displayed on the RFID tag of the slipper, the reader / writer transmits a write signal to the RFID tag of the slipper. The IC chip of the slipper memorizes the contents of the IC card key, and at the same time, electromagnetic induction is caused by the resonant action of microwaves to generate an electromotive force. The slipper has a built-in battery and the name is displayed on the RFID tag. You can also capture user data and display your name on the display at the same time. However, depending on the battery life, communication accuracy decreases, or you can write to multiple slippers with a single IC card key. Usually, it is desirable not to use batteries. Since it is connected to a personal computer, the display condition can be set only once, or can be set up to twice.

  There are many business establishments that provide slippers for visitors, such as hotels, inns, hospitals (clinics), and offices. Everyone is experiencing the unpleasantness of hygiene due to the necessity of changing to slippers that they don't know who used them, and the potential demand for these slippers with a name display function is high. I think that the. Moreover, as a name display method, an RFID tag communication function and a rewrite card or electronic paper display function, such as creating a customer name card in advance and letting the customer insert it into the slipper or pulling out the finished slipper card, etc. The labor-saving effect due to the omission is great. In addition, there is an unforeseeable application to other technologies that can reliably identify the user himself / herself using an IC card key or a medical examination ticket. Regarding disinfection, slippers with photocatalyst processing are provided to users after UV irradiation or cleaning, so that hygiene can be managed reliably and can contribute to the prevention of infectious diseases and the spread of ringworms such as athlete's foot. Recently, each person's awareness of the prevention of athlete's foot has been gradually improving, and it is possible that the number of visitors will increase by putting on their shoes, disinfecting slippers, and providing a service to fill in the names of visitors to the disinfected slippers. , It will lead to improvement of business performance of the establishment that adopts this system.
