JP5896216B2 - Warmth with antenna and movement detection device using the same - Google Patents

Description

  The present invention relates to a cloth warming provided with an antenna for detecting a wireless ID tag such as an RFID and a movement detection device using the same.

  In recent years, wireless ID tags such as RFID have been miniaturized, and a system for identifying a wireless ID tag by attaching it to various mobile bodies has been developed. In order to recognize the wireless ID tag, an antenna for transmitting and receiving information to and from the wireless ID tag is required.

  Due to the miniaturization of the wireless ID tag, there are fewer restrictions on the mounting position with respect to the moving body. For example, even when attaching to a human being, the wireless ID tag is attached to an existing object to be worn such as clothes, personal belongings and personal belongings to identify and position the person. Recognition is possible. Therefore, the antenna that transmits and receives to / from the wireless ID tag is also attached to various existing items close to the wireless ID tag when the person moves, so that identification and position recognition can be performed in a natural operation without restricting human movement. It is desired to do.

  As a management method using a wireless ID tag, for example, in Patent Documents 1 and 2, an RFID receiving antenna and an infrared detection device are provided at an entrance for detecting entrance and exit, and the infrared detection device detects passage of a human body and possesses it. A management system is described in which a holder who has passed through an RFID tag is identified and the entrance / exit is grasped.

  In addition, as an article identification management method, for example, in Patent Documents 3 and 4, an ID tag is attached to an antenna by passing an article attached with an ID tag through a warm sheet-like sheet body provided with an antenna. The point to be read is described.

  Further, as a fabric provided with an antenna, for example, in Patent Document 5, a non-electrically conductive yarn made of polyester fiber or the like is used as a warp, and an electrically conductive yarn made of metal fiber or the like is used as a weft. A fabric antenna woven using is described. Further, in Patent Document 6, at least part or all of a conductive region and an insulation formed by an arrangement pattern of conductive portions are formed on a woven fabric composed of gold and silver threads having conductive portions and conductive silk yarns. An antenna comprising a slot having a characteristic is described.

JP 2001-028090 A JP 2003-021679 A JP-A-11-301843 JP 2009-290512 A JP 2008-546209 A JP 2009-044439 A

  As described in Patent Documents 1 and 2, in the conventional entrance / exit management system, it is necessary to detect the passage of the RFID tag holder with an infrared detection device, and the RFID attached to a position away from the holder. Since detection is performed by the receiving antenna, there is a possibility that the holder cannot be accurately identified when a plurality of holders pass in close proximity.

  As described in Patent Documents 3 and 4, when an article having an ID tag attached to a warm sheet-like sheet body is passed in one direction so as to contact, the article can be accurately contacted by sequentially contacting the article. Although it can be specified and read, it is not assumed that the owner of the ID tag passes at random.

  Moreover, although the metal fiber is used in patent document 5, when a metal fiber is scarcely stretchable and it combines with a synthetic fiber to make a woven fabric, it has the fault of being disconnected or bent without following the expansion and contraction of the synthetic fiber. Yes, it is difficult to use as an antenna material. In Patent Document 6, a gold-silver thread obtained by vapor-depositing aluminum on a base material made of PET is used as a conductive thread. However, the gold-silver thread has a drawback that it is easily disconnected and has a high electric resistance. When the gold and silver thread is used in a twisted state, there is a problem in that the antenna characteristics are not constant because the conductive part is not uniform in the twisted part when viewed from a predetermined direction. In any case, it cannot be said that the fabric has sufficient performance as an antenna for wireless communication such as RFID.

  Accordingly, the present invention provides a warmth provided with an antenna that can accurately read ID data when the owner of the wireless ID tag passes and can identify the passing direction, and a movement detection device using the same. It is intended.

  The warming according to the present invention includes a pair of antenna holders in which a plurality of antenna wires are arranged and held at a predetermined interval on a sheet-like base body made of an insulating material that has flexibility, and the antenna holder A conductive sheet body that is formed to have a size capable of covering the area where the antenna lines are arranged and shields radio waves, and the conductive sheet body arranged the antenna lines between a pair of the antenna holding bodies. It is arranged at a position facing the region, laminated and integrated, and an insulating material is provided between the conductive sheet body and the antenna wire so that they do not contact each other. Furthermore, the base body of the antenna holder is a cloth body composed of ground yarn made of insulating yarn having a relative dielectric constant of 4 or less, and the antenna wire of the antenna holder has the same core as the ground yarn. It consists of a conductive yarn having a resistance of 1 Ω / m to 15 Ω / m, which is obtained by covering the yarn with a metal fiber. Furthermore, the said insulating material consists of the said ground thread of the said cloth body. Further, the antenna line is held by a ground yarn that is inserted and intersected in the warp direction and / or the weft direction of the cloth body. Further, the antenna line is held by a sewing thread that is sewn into the cloth body so as to intersect the antenna line.

  The movement detection device according to the present invention reads ID data based on the above-described warmth and a signal from a wireless ID tag received by the antenna wire held by the antenna holding body and receives it by any of the antenna holding bodies. An information reading unit for identifying whether or not it has been performed, and a detection processing unit for detecting a moving direction based on identification data of the antenna holder.

  Since the warming according to the present invention has the above-described configuration, the conductive sheet body is disposed between the pair of antenna holding bodies that hold the antenna wires, and is integrated and stacked. When the tag touches warmly, the ID tag reading operation is performed only on the antenna line of the antenna holder on one side, and the antenna line of the antenna holder on the other side is shielded from radio waves by the conductive sheet body. The tag reading operation is not performed. For this reason, it is possible to detect from which side of the warmth the ID tag has arrived, and to detect the moving direction by identifying which antenna holding body of the pair of antenna holding bodies has performed the reading operation. be able to.

  Further, the substrate of the antenna holder is a cloth body composed of ground yarn having a relative dielectric constant of 4 or less, and an antenna wire made of conductive yarn having a resistance of 1Ω / m to 15Ω / m is held on the cloth body. Therefore, it can be used as a highly sensitive antenna using a low-resistance antenna wire for the ground structure of the insulator.

  In addition, since the conductive wire with metal fiber covering the core yarn is used as the antenna wire, the antenna wire is excellent in flexibility and stretchability, and the ground structure is curved in a state of being closely held on the cloth body. Even when it is deformed, it can follow the deformation of the cloth body. And since the metal wire is covered so as to be wound around the core yarn, it has the same mechanical characteristics as the yarn made of synthetic fiber, and even when the antenna wire is curved, it does not break, and The metal fiber does not bend.

  In addition, by using the same thread as the ground thread of the cloth body as the core thread of the conductive thread, the conductive thread can have the same flexibility and stretchability as the ground thread, and the antenna wire is held in close contact with the cloth body. In this state, both can be deformed in the same way without shifting.

  Hereinafter, embodiments according to the present invention will be described in detail. The embodiments described below are preferable specific examples for carrying out the present invention, and thus various technical limitations are made. However, the present invention is particularly limited in the following description. Unless otherwise specified, the present invention is not limited to these forms.

  FIG. 1 is a front view related to a warming that is an embodiment according to the present invention, and FIG. 2 is an exploded perspective view of the warming. The warm bath 1 is suspended with a slit S through which a person passes, and is laminated and integrated so as to sandwich a conductive sheet body 7 that shields radio waves between a pair of antenna holding bodies 2a and 2b. Yes. The antenna holding body 2a has a plurality of antenna wires 3a arranged at predetermined intervals on a flexible sheet-like base made of an insulating material, and the antenna holding body 2b is also a similar sheet-like base. A plurality of antenna wires 3b are arranged and held at predetermined intervals.

  The conductive sheet body 7 is formed in a size that can cover the area where the antenna wires 3a and 3b of the antenna holding bodies 2a and 2b are arranged. Therefore, although the radio wave transmitted from the antenna holding body 2a side can be received by the antenna wire 3a of the antenna holding body 2a, the radio wave is shielded by the conductive sheet 7, so that the antenna line of the antenna holding body 2b is used. It cannot be received with 3b. Moreover, although the electromagnetic wave transmitted from the antenna holding body 2b side can be received by the antenna line 3b, it cannot be received by the antenna line 3a. Therefore, by identifying which of the antenna line 3a of the antenna holding body 2a and the antenna line 3b of the antenna holding body 2b the radio wave is received, the radio wave is transmitted from the antenna holding body 2a side or the antenna holding body 2b side. It is possible to specify that the call has been sent. When a radio wave is transmitted from the antenna holding body 2a side, it is moved from the antenna holding body 2a side to the antenna holding body 2b side, and when a radio wave is transmitted from the antenna holding body 2b side. Is moving from the antenna holding body 2b side to the antenna holding body 2a side, so that the moving direction can be detected.

  Each antenna line 3a and 3b is connected to the reader 5 via wiring cords 4a and 4b, respectively. Then, when the wireless ID tag approaches the antenna line 3a or 3b, a signal received from the wireless ID tag to the antenna line 3a or 3b is input to the reading device 5, and the reading device 5 reads the received ID data. Which antenna line of the antenna holders 2a and 2b is used for reception is identified. Further, the antenna wires 3a and 3b are connected in parallel to the reader 5 via the wiring cords 4a and 4b, and a method of identifying the IC tag by switching them alternately in the reader 5 is suitable. ing. By using this identification method, radio wave interference between the antenna lines 3a and 3b is eliminated, and a good recognition process can be performed.

  The read ID data is transmitted from the reading device 5 to the detection processing device 6 by wireless communication together with the received identification data of the antenna holder. The detection processing device 6 stores the transmitted ID data and the identification data of the antenna holder, determines the movement direction based on the identification data, and creates movement information associated with the ID data. When the warm bath 1 is suspended from the doorway, the movement information can be created as the entrance / exit information. The data communication between the reading device 5 and the detection processing device 6 may be wired.

  The bases of the antenna holders 2a and 2b are preferably made of an insulating material having a relative dielectric constant of 4 or less, such as a cloth body made of ground yarn made of insulating yarn, a synthetic resin film having insulating properties, etc. A flexible sheet body can be used. In the case of a film, examples of the material include PET (polyethylene terephthalate), PP (polypropylene), and PE (polyethylene). In the case of using a fabric body, a fabric such as a woven fabric, a knitted fabric or a non-woven fabric used for normal warming may be used. As the ground yarn or fiber for organizing the fabric, PET, PTT (polytrimethylene terephthalate) or PBT ( Polyester fiber such as polybutylene terephthalate), nylon (polyamide fiber), aramid (aromatic polyamide fiber), polyolefin fiber such as polypropylene or polyethylene, synthetic fiber such as acrylic, chemical fiber such as rayon and acetate, cotton, hemp , Natural fibers such as wool or silk. Moreover, you may use the composite fiber which mixed multiple types of these fibers.

  The antenna line 3a is composed of a conductive line, and as shown in FIG. 3, a dipole antenna in which a pair of conductive lines 30 and 31 arranged in a straight line along a direction orthogonal to the formation direction of the slit S is combined. The shape is set. The ends of the conductive lines 30 and 31 facing each other are spaced apart from each other, and the frequency characteristics of the antenna are determined based on the distance between the ends of the conductive lines 30 and 31 opposite to the opposite ends. Is done. Note that the interval between the end portions of the conductive lines described above is set not by the actual length of the conductive lines but by the linear distance between the end portions in plan view. A plurality of antenna wires 3a are arranged along the slits S at a predetermined interval. The antenna wire 3b of the antenna holder 2b has the same configuration as the antenna wire 3a and is arranged along the direction in which the slits S are formed. In FIG. 3, an example of a dipole antenna is described as the shape of the antenna line, but other antenna shapes such as a loop antenna and a microstrip antenna can also be used.

  Conductive wires can be used for the antenna wires 3a and 3b. When a film-like substrate is used, a wiring pattern made of a conductive material such as copper or aluminum can be formed on the surface of the substrate, or the wiring pattern can be embedded in the substrate. When a cloth body is used for the substrate, a conductive thread can be used as the antenna wire. Examples of the conductive yarn include a yarn or braid obtained by twisting conductive fibers such as metal fibers and metal-plated fibers, or a yarn or braid obtained by twisting such conductive fibers together with fibers made of an insulating material. In particular, when a metal fiber such as copper fiber, tin-plated copper fiber, tin bronze fiber, or stainless steel is covered around the core yarn, it is excellent in followability when it is closely attached to the cloth body. As the core yarn, polyester fibers such as PET, PTT or PBT, nylon (polyamide fibers), aramid (aromatic polyamide fibers), polyolefin fibers such as polypropylene or polyethylene, synthetic fibers such as acrylic, rayon, acetate, etc. A yarn made of a natural fiber such as a chemical fiber, cotton, hemp, wool or silk may be used, and a yarn made of a composite fiber obtained by mixing a plurality of these fibers may be used.

  As the covering process, there are a single covering process and a double covering process. FIG. 4 shows a conductive thread that has been subjected to a double covering process in which metal fibers 34 are wound around the core thread 33 in a double manner. Yes.

  The electrically conductive yarn desirably has an electrically low resistance, and the electrical resistance is preferably set to 1 Ω / m to 15 Ω / m. When the electric resistance exceeds 15 Ω / m, the sensitivity as an antenna deteriorates.

  As for the mechanical properties of the conductive yarn, when the number of twists of the metal fiber to be covered is 3000 T / m or more, it has almost the same properties as the core yarn. By using a conductive yarn with metal fibers covering the core yarn for the antenna wire, a flexible and stretchable antenna wire can be obtained, and the fabric body is curved when the antenna wire is closely held on the fabric body. Or even if it expands and contracts, it becomes possible to follow the deformation of the cloth body without the antenna line being disconnected or displaced.

  FIG. 5 is an enlarged view of the fabric portion in the case where the antenna wire 3a or 3b is held tightly on a fabric body woven by double weaving. The antenna wire 3a or 3b is held in close contact with the fabric on the upper surface side of the double woven fabric. Conductive yarns, which are antenna wires, are arranged between the wefts 20, and warps 21 are alternately sandwiched between the upper and lower sides of the conductive yarns and are held in the same manner as the wefts 20. For this reason, the antenna wire is held tightly on the cloth body and does not fall off. Moreover, since the conductive yarn has flexibility and stretchability, even if the cloth body is deformed, it can be deformed following the deformation, and troubles such as disconnection do not occur. If the same weft 20 as the core yarn of the conductive yarn is used, the mechanical properties of the conductive yarn can be set almost the same as the warp yarn 21, and the conductive yarn follows the deformation of the fabric more smoothly. Is possible.

  Further, since the warp yarns 21 intersect with the conductive yarns at substantially equal intervals, it is possible to set the length of the conductive yarns to be closely held based on the number of warp yarns 21 that intersect. Therefore, when weaving the cloth body, weaving by inserting a predetermined number of warp yarns as weft, weaving the cloth body, leaving the portion retained by the warp after weaving the cloth body, cutting the conductive yarn, and as an antenna wire It can also be used. By forming the antenna line in this manner, the interval between the ends of the conductive yarn can be set with high accuracy, and the sensitivity of the antenna can be improved.

  In this example, since the cloth body is woven by double weaving, it has a configuration in which a woven fabric having electrical insulation is disposed on the lower surface of the antenna line, and the antenna line is formed of the conductive sheet body 7. It is designed to prevent touching.

  In the above-described example, the conductive yarns are arranged in the weft direction. However, the conductive yarns can be arranged and held in the warp direction. Also good.

  FIG. 6 is an enlarged view of the fabric portion when the antenna wire 3a or 3b is held tightly by the sewing thread 22 on a fabric woven by plain weaving. In this case, the conductive wire as the antenna wire is linearly arranged on the surface of the cloth body and fixed with an adhesive or the like, and is sewn alternately on both sides of the antenna wire with the sewing thread 22 using a sewing machine or the like. The antenna wire is kept in close contact with the cloth body. In addition to the conductive yarn, a material having an antenna pattern on the surface or inside of the film can be fixed to the cloth body in the same manner. When such a film material and a cloth body are used, the deformation behavior such as bending is different, and therefore, a method of fixing by sewing or fixing to an insertion portion formed on the cloth body without using an adhesive or the like is preferable.

  When the conductive yarn is fixed by sewing as the antenna wire, any of a woven fabric, a knitted fabric or a non-woven fabric may be used as the fabric body. In addition, since the conductive thread is attached to the cloth body later, it can be attached by checking whether the distance between the antenna lines is set while measuring the length of the conductive thread that has been sewn. On the other hand, it can be fixed with high accuracy. In addition, when the sewing interval of the sewing thread 22 can be set at an equal interval, the length of the conductive thread can be set based on the number of times of sewing with respect to the cloth body.

  The conductive sheet 7 is made of a material such as a metal foil that is flexible and has excellent followability when laminated with an antenna holder, and shields or absorbs radio waves in radio communication using RFID. Good. In addition, a material having deformation followability and bending durability when installed as a warm bath is preferable. For example, a synthetic resin film having a conductive layer, a thin fabric made of conductive fibers, a metal plating or a conductive material is coated. Examples include fabrics. Moreover, it is preferable that the thickness of the electroconductive sheet body 7 shall be 2 mm or less from a viewpoint of the deformability as a warmth or weight reduction.

  When the conductive sheet 7 and the antenna holders 2a and 2b are laminated, an insulating material is provided between the antenna wires 3a and 3b and the conductive sheet 7 so that they do not negotiate. In the above-described example, when the substrate of the antenna holding body is a film, it is possible to prevent contact by interposing a part of the substrate made of an insulating material between the antenna wire and the conductive sheet body. Even in the case where the substrate of the antenna holder is a cloth body, it is possible to prevent the ground yarn made of insulating yarn from contacting by being interposed between the antenna wire and the conductive sheet body. Even when the antenna wire is exposed to the outside, if the surface of the antenna wire or the conductive sheet is coated with an insulating material in advance, it is possible to prevent the two from coming into contact and electrically connected. Is possible.

  FIG. 7 is an explanatory diagram relating to a method for producing the warm bath 1. In this example, the antenna holder 2b is placed so that one side where the antenna wire 3b is held faces downward, and the conductive sheet 7 is stacked thereon. The conductive sheet 7 is disposed so as to cover the entire area where the antenna wires 3b are arranged. Then, the antenna holder 2 a is placed on the conductive sheet body 7, and the antenna holder 3 a is arranged so that the region where the antenna lines 3 a are arranged overlaps the conductive sheet body 7. Then, the three sheets are integrated in a stacked state. When the base of the antenna holder is a synthetic resin film, the antenna holders can be integrated by heat fusion. Further, when the base of the antenna holder is a cloth body, the antenna holders can be integrated by sewing or the like. When the sheets are laminated and integrated in the manufacturing method described above, the sheets can be integrated using a pressure-sensitive adhesive or an adhesive. When an adhesive or the like is used, it is preferable that the sheet is partially bonded and fixed in a dot shape or a line shape in order to maintain warmth flexibility.

  FIG. 8 is an explanatory diagram relating to another method for producing the warm bath 1. In this example, a sheet 23 having a size in which the antenna holding bodies 2a and 2b are combined is used, and antenna lines 3a and 3b and wiring cords 4a and 4b are respectively provided on one side of a half area defined by the center line T of the sheet 23. And the sheet 23 is set so that one side holding the antenna wires 3a and 3b faces downward (FIG. 8A). Next, the conductive sheet body 7 is overlaid on the half area of the sheet 23 and arranged so as to cover the entire area where the antenna wires 3b are arranged. Then, the sheet 23 is bent along the center line T (FIG. 8B) and stacked and integrated. In the case of integration, it can be performed by heat fusion or sewing, as in the example shown in FIG. In this case, half of the sheet 23 becomes the antenna holder 2a, and the other half becomes the antenna holder 2b.

  FIG. 9 is an explanatory diagram when the holder M of the wireless ID tag passes the warmth 1. As shown in FIG. 10, the holder M wears pads M1 and M2 with wireless ID tags attached to both shoulder portions. A plurality of strip-like RFID tags are arranged at predetermined intervals on the pads M1 and M2, and the longitudinal direction of the pads M1 and M2 is as horizontal as possible in a state where they are arranged along the shoulder line. Is set to The M1 and M2 RFID may be installed in any direction that can be detected by a warm antenna line, and at least one RFID may be installed in the pad. The mounting positions of M1 and M2 may be on either the left or right side, and may be set at a position that can be easily recognized when passing warmth such as the cuffs, back, and chest as well as the shoulders.

  In the state in which the warm bath 1 is suspended, the slit S is set in the vertical direction, so that the antenna lines 3a and 3b orthogonal to the slit S are set in the substantially horizontal direction (FIG. 9A). Then, when the holder M moves forward from the antenna holder 2b toward the slit S and passes through the warm bath 1 so as to scrape the fabric portions on both sides of the slit S, the antenna holders 2b on both sides are moved to both sides of the holder M. It will be in the state which contacted the shoulder part (FIG.9 (b)). Therefore, the RFID tag disposed on the pads M1 and M2 comes close to the antenna line 3b of the antenna holder 2b that comes into contact. Then, the antenna holding body 2b in contact with the pads M1 and M2 moves relative to slide so as to be in contact with the pads M1 and M2 as the holder M moves forward, and the antenna line 3b is sequentially moved to the pads M1 and M2. It is set in a state of being close to the RFID tag disposed in the.

  In this way, the radio wave transmitted from the RFID tag is received on the antenna line 3b of the antenna holder 2b. On the other hand, in the antenna holding body 2a, the radio wave transmitted from the RFID tag is shielded by the conductive sheet 7, so that the radio wave is not received. Similarly, when the holder M passes the warmth 1 from the antenna holder 2a side, only the antenna holder 2a receives radio waves transmitted from the RFID tag. In order to reliably determine that a plurality of bearers M have passed the warmth, it is better that the recognizable distance of the antenna line with respect to the RFID tag is short, and generally a pedestrian does not approach the previous pedestrian. When walking, it is preferable to set the recognition distance of the antenna line to 30 cm or less because it walks with an interval from 30 cm. Also, if the RFID tag cannot be recognized unless it is in contact with the antenna line, recognition failure is likely to occur. Therefore, it is necessary to be able to recognize even when the RFID tag does not contact the antenna line, and the antenna line can be recognized. It is desirable that the distance is set to 2 cm or more. In consideration of such a recognizable distance, the frequency of the RFID tag may be set to 2.45 GHz or the UHF band (860 MHz to 960 MHz), for example.

  The warmth according to the present invention is made of a flexible material like the normal warmth and holds the linear antenna wire in close contact with the antenna holder. In addition, the design can be realized, and it can be installed as an interior product without a sense of incongruity even when it is suspended from an entrance or hallway in a building.

  In addition, since the reading device and the warm bath can be easily attached as a set, it is possible to easily manage the movement information by wireless communication by attaching it to a necessary place in an existing building. For example, it is suitable for installing in a care facility and confirming movement information for a demented care recipient and managing entrance / exit.
