  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(First embodiment)
3A and 3B show an electronic lock according to the first embodiment of the present invention. The electronic lock 300 includes a case 301, a cylinder 302, a thumbturn 303 disposed at a position facing or substantially facing the cylinder 302 with respect to the case 301, and a case 301. The first transmitter 304 and the second transmitter 305 disposed in the interior of the antenna, and the electromagnetic shielding member disposed between the first transmitter 304 and the second transmitter 305. member) 306. As shown in FIG. 2, an electronic lock that electronically unlocks or unlocks and locks can be configured by attaching an unlocking assisting device (not shown) around the thumb turn 303, which is known to those skilled in the art. The details are not described here. In the illustrated example, a front 307, a deadbolt 308, a latch bolt 309, a handle 310, and the like are also shown. It is not limited. In addition, an electronic lock can be configured by providing a mechanism for electronically unlocking or unlocking and locking inside the case 301 as necessary by communicating with the outside. Will not be described here. In addition, all the components necessary for the electronic lock need not be provided in the vicinity of the case 301, and necessary operations may be performed by communicating with the outside.

  The first transmitter 304 transmits periodically or intermittently, and can be arranged using the space inside the case 301. From the radio wave emitted by the first transmitter 304, a first ID for identifying the first transmitter 304 and the radio field intensity of the radio wave can be determined. For example, the Bluetooth (registered trademark) standard, the Bluetooth Low Energy (BLE) standard, the Wi-Fi (registered trademark) standard, the ZigBee (registered trademark) standard, the Wi-SUN (registered trademark) standard, and the EnOcean (registered trademark) standard A compliant transmitter may be used.

  The second transmitter 305 also has a similar function, and from the radio wave, a second ID for identifying the second transmitter 305 and the radio wave intensity of the radio wave can be determined. Although it is good to arrange | position in the position which opposes the 1st transmitter 304 in the inside of case 301, or the position which opposes substantially (FIG. 4), it does not necessarily need to oppose. The second transmitter 305 is disposed on the indoor side of the electronic lock 300 with respect to the first transmitter 304.

  When the electronic lock 300 is provided at the entrance of the room, the electromagnetic wave shielding member 306 disposed between the first transmitter 304 and the second transmitter 305 is located outside the first transmitter 304 when the electronic lock 300 is provided at the entrance of the room. The radio wave of one transmitter is shielded according to the measurement position of the outdoor or indoor so that the radio wave intensity is stronger and the radio wave intensity of the second transmitter 305 is stronger on the indoor side. Alternatively, the difference obtained by subtracting the radio wave intensity of the second transmitter 305 from the radio wave intensity of the first transmitter 304 is set to be equal to or greater than a predetermined threshold. It can also be said that nonuniformity of intensity is given to the radio waves of each transmitter in the inside and outside of the room. If it does in this way, as will be described later, it becomes possible to specify the user position based on the electronic lock or the door on which the electronic lock is provided with high accuracy.

  As a specific example, the first transmitter 304 and the second transmitter 305 have the same or substantially the same radio wave intensity before attenuation, and the first transmitter 304 and the second transmitter 305 are placed between the first transmitter 304 and the second transmitter 305. The structure which arrange | positions a sheet-like metal is mentioned. Examples of the electromagnetic wave shielding member 306 include tapes, sprays, coating agents, paints, and the like in addition to metals.

  The electronic lock 300 can be used by being provided on any door, but depending on the material of the door, the radio waves of both transmitters may be shielded. A relatively low rate may be used at least in part.

(Second Embodiment)
In the first embodiment, the case where the first and second transmitters are fixed to the electronic lock has been described. However, the first and second transmitters may be fixed not to the inside of the lock case but to the opening / closing portion of the door provided with the electronic lock. it can.

  FIG. 5 shows the indoor side of the door according to the second embodiment of the present invention. The door 500 includes an opening / closing part 501, an electronic lock 502, a handle 503, a first transmitter 504 (not shown for the opposite side of the opening / closing part 501) and a second transmitter fixed inside the opening / closing part 501. A transmitter 505 and an electromagnetic wave shielding member 506 disposed between the first transmitter 504 and the second transmitter 505 are provided.

  The first transmitter 504, the second transmitter 505, and the electromagnetic wave shielding member 506 are not in the lock case, but are fixed inside the opening / closing part 501 at other positions. The form is the same. For example, it can be fixed in a space for accommodating the lock case in the opening / closing part 501.

  The electronic lock 502 can be any electronic lock. All the components necessary for the electronic lock 502 do not have to be provided in the vicinity of the opening / closing unit 501, and necessary operations may be performed by communicating with the outside.

  In addition, the first transmitter 504, the second transmitter 505, and the electromagnetic wave shielding member 506 may be fixed on the indoor outer surface of the opening / closing member 501. In this case, as shown in FIG. 2, an electronic lock 502 for electronically unlocking or unlocking and locking can be configured by attaching an unlocking assisting device around the thumb turn and accommodated inside the electronic lock 502. it can. In this way, the user can turn the conventional lock into an electronic lock simply by attaching the unlocking assist device around the thumb turn, and, as will be described later, the user position based on the electronic lock is highly accurate. Can be specified.

  Depending on the material of the opening / closing part of the door 500, the radio waves of both transmitters are shielded. For example, a wooden door or the like having a relatively low radio wave shielding rate may be used at least in part.

  The electromagnetic wave shielding member 506 is preferably provided in a sufficient size with respect to the first transmitter 504 and the second transmitter 505 in order to achieve the purpose of shielding, and has a circular shape, a rectangular shape, a square shape, or the like. Can do.

(Third embodiment)
In 2nd Embodiment, although the 1st transmitter, the 2nd transmitter, and the case where the electromagnetic shielding member was fixed to the indoor side outer surface of the opening / closing part of a door was demonstrated as one aspect, the 1st transmission It is also possible to fix the machine on the outdoor surface on the outside and the second transmitter on the outside surface on the indoor side.

  In FIG. 6, the side surface of the door concerning the 3rd Embodiment of this invention is shown. The door 600 is fixed to the opening / closing part 601, the electronic lock 602, the handle 603, the first transmitter 604 fixed to the outdoor side outer surface 601A of the opening / closing part 601, and the indoor side outer surface 601B of the opening / closing part 601. The second transmitter 605, the electromagnetic wave shielding member 606A disposed between the first transmitter 604 and the outdoor outer surface 601A, and the second transmitter 605 and the indoor outer surface 601B. An electromagnetic wave shielding member 606B. The first transmitter 604 and the second transmitter 605 may be opposed to or substantially opposed to the opening / closing unit 601, but are not necessarily opposed to each other. One of the electromagnetic wave shielding members 606A and 606B can be omitted. Further, the electromagnetic wave shielding member may be disposed at another position between the first transmitter 604 and the second transmitter 605 such as the inside of the opening / closing part 601. In any case, depending on the outdoor or indoor measurement position, the radio wave intensity of the first transmitter 604 is stronger on the outdoor side and the radio wave intensity of the second transmitter 605 is stronger on the indoor side. The radio wave of the transmitter is shielded. Alternatively, the difference obtained by subtracting the radio wave intensity of the second transmitter 605 from the radio wave intensity of the first transmitter 604 is set to be equal to or greater than a predetermined threshold. If it does in this way, as will be described later, it becomes possible to specify the user position based on the electronic lock or the door on which the electronic lock is provided with high accuracy.

  The electronic lock 600 can be used by being provided on an arbitrary door. However, depending on the material of the opening / closing part 601, even if one of the electromagnetic shielding members 606 is omitted or both are omitted, sufficient shielding can be obtained. Therefore, for example, a metal or the like having a relatively high radio wave shielding rate may be used at least in part.

  Further, as shown in FIG. 2, an electronic lock 602 that electronically unlocks or unlocks and locks is configured by attaching an unlocking assisting device around the thumb turn, and the second transmitter 605 (and the electromagnetic wave shielding member). 606B) can be accommodated inside the electronic lock 602.

(Fourth embodiment)
In the third embodiment, the case where the first transmitter on the outdoor side is fixed to the outer outer surface of the door has been described, but the first transmitter can also be provided near the outdoor side of the door.

  In FIG. 7, the side surface of the door concerning the 4th Embodiment of this invention is shown. The door 700 includes an opening / closing part 701, an electronic lock 702, a handle 703, a first transmitter 704 fixed near the outdoor side other than the outdoor side outer surface 701A of the opening / closing part 701, and the indoor side outer surface of the opening / closing part 701. A second transmitter 705 fixed to 701B, and an electromagnetic wave shielding member 706 disposed between the second transmitter 705 and the indoor side outer surface 701B. The electromagnetic wave shielding member can be omitted. Further, the electromagnetic wave shielding member 706 may be disposed inside the opening / closing part 701. For example, the first transmitter 704 can be fixed to the ceiling or the like outside the door 700 by being separated from the door 700. In addition to the ceiling, it can be fixed separately from the door 700 on a wall having an entrance provided with the door 700. In any case, depending on the outdoor or indoor measurement position, the radio wave intensity of the first transmitter 704 is stronger on the outdoor side and the radio wave intensity of the second transmitter 705 is stronger on the indoor side. The radio wave of the transmitter is shielded. Alternatively, the difference obtained by subtracting the radio wave intensity of the second transmitter 705 from the radio wave intensity of the first transmitter 704 is set to be equal to or greater than a predetermined threshold value. If it does in this way, as will be described later, it becomes possible to specify the user position based on the electronic lock or the door on which the electronic lock is provided with high accuracy.

  Although the electronic lock 700 can be used by being provided on an arbitrary door, depending on the material of the opening / closing portion 701, sufficient shielding can be obtained even if the electromagnetic wave shielding member 706 is omitted. It is preferable to use one having a relatively high shielding rate.

  Further, as shown in FIG. 2, an electronic lock 702 that electronically unlocks or unlocks and locks is configured by attaching an unlocking assisting device around the thumb turn, and the second transmitter 705 (and the electromagnetic wave shielding member). 706) can be accommodated inside the electronic lock 702.

  In addition, since the first transmitter 704 is separated from the door 700, it may be understood that the first transmitter 704 does not constitute the door 700. In that case, the door 700 and the first transmitter 704 It should be added that the door system includes the transmitter 704.

  In the present embodiment, the first transmitter 704 is separated from the door 700 and the second transmitter 705 is provided on the door 700. Conversely, the outdoor first transmitter 704 is connected to the door 700. It is also possible to separate the second transmitter 705 on the indoor side from the door 700.

(Fifth embodiment)
A method for specifying the user position based on the door having the electronic lock described in the first to fourth embodiments will be described.

  For simplicity, it is assumed that the radio wave intensity before attenuation of the first transmitter and the second transmitter is the same or substantially the same, and an electromagnetic wave shielding member is disposed between these transmitters.

  When there is a user who has a wireless terminal outside the room, the radio field intensity D1 of the first transmitter received by the radio terminal is greater than the radio field intensity D2 of the second transmitter attenuated by the electromagnetic shielding member. Become. On the contrary, D2 becomes larger than D1 when it is on the indoor side. Therefore, if D1-D2> 0, it can be specified that the wireless terminal exists not on the indoor side but on the outdoor side.

  Furthermore, when the magnitude of D1 is larger than the predetermined outdoor threshold, it means that the attenuation that proceeds according to the distance is not large, and the wireless terminal is within the distance corresponding to the outdoor threshold from the first transmitter. It can be specified that it exists. This range is referred to as a “first outdoor area” 801.

  When the magnitude of D1 is equal to or less than the predetermined outdoor threshold, it can be specified that the wireless terminal is outside the room and is outside the first outdoor area. This range is referred to as a “second outdoor area” 802.

  For example, the outdoor threshold value may be selected in a range of −80 dBm to −70 dBm. For example, the radio wave intensity corresponding to a position at a distance of about 2 to 3 m from the entrance of the room or a door provided there can be used.

  When the outdoor threshold value is a constant value, as shown in FIG. 8, the boundary between the first outdoor region 801 and the second outdoor region 802 is generally an arc shape, but depending on the environment such as the shape of the room, a plurality of It is also possible to select a different outdoor threshold at the point. Accuracy can be increased by adjusting the threshold according to such an environment.

  When the wireless terminal cannot receive the radio wave emitted by the first transmitter and cannot receive the radio wave emitted by the second transmitter, that is, when D1 and D2 are below a predetermined minimum threshold, the wireless terminal transmits the radio wave. It can be specified that the range of the receivable distance is exceeded. This range is called “out-of-service area”. Since D1-D2 cannot be calculated outside the service area, it cannot be distinguished whether it is the outside service area outside the room or the outside service area on the indoor side, but the radio waves of the first and second transmitters received by the wireless terminal By storing the history of intensity, it is possible to specify that the area is an outdoor area outside the area based on the transition from the second outdoor area to the outside area.

  For example, the minimum threshold may be −100 dBm. In the case of a mobile terminal smartphone, the minimum detectable radio wave intensity is determined by the OS specifications. For example, the radio wave intensity corresponding to a position at a distance of about 20 to 30 m from the entrance of a room or a door provided there may be set as the minimum threshold value.

  Although not shown in the drawing, the same applies to the indoor side. If D1−D2 <0, the wireless terminal is present on the indoor side instead of the outdoor side, and when the magnitude of D2 is greater than a predetermined indoor threshold, If the magnitude of D2 is equal to or smaller than the predetermined indoor threshold value, then “second indoor area”, when radio waves emitted by the first and second transmitters cannot be received, that is, D1 and D2 are predetermined. If it is less than or equal to the minimum threshold, it can be set as an “out-of-service area”. Similar to the outdoor side, when the transition from the second indoor area to the out-of-service area is made from the history of radio wave intensity, it is possible to specify that this out-of-service area is an out-of-service area in the room.

  According to the user position specifying method according to the present embodiment, the wireless terminal is moved from the door based on the difference between the radio field intensity of the first transmitter and the radio field intensity of the second transmitter and the magnitude of the radio field intensity. It is possible to specify with high accuracy which region is divided by the distance.

  Further, the correspondence between the radio wave intensity and the distance from the entrance of the room or the door provided there is determined, for example, by measuring in advance, and a correspondence table holding the correspondence is determined based on the received radio wave intensity. It is also possible to specify the distance from the entrance or door to the outside or the inside by referring to it.

(Sixth embodiment)
When the user position is specified with high accuracy by the user position specifying method described in the fifth embodiment, as described above, the following becomes possible.

  That is, in the wireless terminal possessed by the user, by executing a program for performing the above-described identification method and storing the history of the user position, the inside / outside from the first outdoor area to the first indoor area is stored. It is possible to acquire a history with high accuracy of movement (entrance) and internal / external movement (exit) from the first indoor area to the first outdoor area. It is difficult to distinguish between entering and leaving only by opening and closing records of the electronic lock, and when a plurality of people pass by opening and closing at once, it is not possible to obtain an accurate entry / exit history. The method of specifying the user position used by the two transmitters according to the present invention significantly improves the reliability of the entry / exit history.

  Instead of storing the history of the user position in the wireless terminal, it is also possible to acquire the entry / exit history similarly by storing the history of the radio field intensity of the first and second transmitters received by the wireless terminal. It is.

(Seventh embodiment)
When the user position is specified with high accuracy by the user position specifying method described in the fifth embodiment, as described above, the following becomes possible.

  That is, by storing the history of the user position, the movement from the second outdoor area to the first outdoor area, that is, the approach from the outdoor to the entrance of the room can be detected. Accordingly, the unlock signal can be transmitted to the wireless terminal.

  Specifically, when the movement is detected (S901), the mobile terminal starts detection of the electronic lock by a predetermined communication method according to the detection (S902). Examples of the predetermined communication method include Bluetooth standard, BLE standard, Wi-Fi standard, ZigBee standard, Wi-SUN standard, EnOcean standard, Z-Wave standard, and the like. Then, ZigBee, Wi-SUN, EnOcean, Z-Wave standards, etc. cannot receive radio waves. At this time, first and second IDs for identifying the first and second transmitters are determined based on radio waves from the first and second transmitters received by the wireless terminal, and the first and second IDs are determined. Since the ID of is associated with a specific electronic lock, the wireless terminal can specify the electronic lock to be detected. The association can be managed by a management server on the Internet with which each mobile terminal can communicate.

  When the mobile terminal reaches a position where it can be connected to the electronic lock, a connection is established with the electronic lock without requiring the operation of the user of the mobile terminal (S903). When the electronic lock emits radio waves periodically or intermittently, the mobile terminal can pick up the radio lock and connect. Although some user action may be required, the unlocking experience can be improved by making it unnecessary.

  After establishing the connection, the mobile terminal transmits an unlock signal to the electronic lock (S904). The unlocking signal can be acquired by requesting an unlocking signal for a specific electronic lock whose connection has been established to a management server on the Internet with which the wireless terminal can communicate. When the unlocking signal is requested, the management server can encrypt the unlocking signal and transmit it to the portable terminal. From the viewpoint of security, the unlocking signal can be configured not to unlock even if the unlocking signal is intercepted and the same signal is reproduced.

  The electronic lock receives an unlock signal. After receiving the unlocking signal, the user may be asked for the final input for unlocking, but this point can also be automated.

  The portable terminal includes a processing unit 1001 such as a CPU, a storage unit 1002, a wireless communication unit 1003, and a display unit (not shown) (FIG. 10), reads a program stored in the storage unit, and processes the processing unit. By executing the above, each function of the above transmission method can be realized, and a transmission device for an unlocking signal can be configured.

  In the above description, the detection of the electronic lock is started in response to detecting the movement from the second outdoor area to the first outdoor area, but the movement from the outdoor area outside the area to the second outdoor area is started. It is also possible to recognize the approach to the entrance from the outside, triggered by the movement from the outdoor area outside the area to the first outdoor area.

  The user position can also be specified when a predetermined time set for each region has elapsed in each region. For example, when the outdoor threshold value between the first outdoor area 801 and the second outdoor area 802 is set to −80 dBm, the user position is immediately set as soon as the radio wave intensity D1 of the first transmitter becomes higher than −80 dBm. One outdoor area 801 may be specified, and the position may be −80 dBm or less, and the user position may be specified as the second outdoor area 802 after a certain period of time has elapsed.

  When the wireless terminal is moved away from the entrance of the room and exits from the first outdoor area 801 to the second outdoor area 802, for example, the wireless terminal can send an unlocking signal again, so that high accuracy may be required. At this time, if a person stays at the entrance of the room and requests for a certain period of time for detection of entering the first outdoor area 801 from the second outdoor area 802, for example, it directly affects the hands-free opening / closing experience. Therefore, it is desirable to set the predetermined time to a short time so that detection can be performed immediately or promptly. By doing in this way, the approach from the outdoor to the entrance of the room called the 1st outdoor area 801 from the 2nd outdoor area 802 can be detected correctly.

  The predetermined time set for each region can be a fixed value for each region, or can be a variable value corresponding to the immediately preceding user position. For example, the predetermined time of the first outdoor area 801 when moving from the second outdoor area 802 to the first outdoor area 801 and the first time when moving from the first indoor area to the first outdoor area 801 The predetermined time of the outdoor area 801 can be distinguished. Accordingly, it is possible to appropriately set a predetermined time for improving the accuracy of the history according to the usage of the user location history.

(Eighth embodiment)
In the fourth embodiment, the case where one of the pair of transmitters is fixed apart from the door has been described, but the pair of transmitters may be provided separately from the door.

  FIG. 11 shows a top view of a wall according to the eighth embodiment of the present invention. The wall 1100 includes a fixed portion 1101, a first transmitter 1102 fixed to the outdoor outer surface 1101A of the fixed portion 1101, and a second transmitter 1103 fixed to the indoor outer surface 1101B of the fixed portion 1101. . An electromagnetic wave shielding member (not shown) may be arranged between both or one of the first transmitter 1102 and the outdoor outer surface 1101A and between the second transmitter 1103 and the indoor outer surface 1101B. Further, an electromagnetic wave shielding member may be disposed inside the fixed portion 1101.

  As a specific example, the first transmitter 1102 and the second transmitter 1103 have the same or substantially the same radio wave intensity before attenuation, and the first transmitter 1102 and the second transmitter 1103 are connected to the wall 1101. The structure arrange | positioned in the position which opposes or substantially opposes is mentioned.

  The user position specifying method described in the fifth embodiment can be similarly applied to a wall including a pair of transmitters according to this embodiment, and the pair of transmitters is fixed to the wall instead of the door. In particular, the accuracy of the entry / exit history can be improved. For example, when the user opens the door and the arrangement relationship between the mobile terminal and the door is as shown in the figure, if these transmitters are fixed to the door as described in the fourth embodiment, the user Even though the mobile terminal has not moved into the room, the radio wave intensity received by the mobile terminal is greater for the indoor transmitter than for the outdoor transmitter, or the difference between the two is predetermined. It becomes more than the threshold value of and it seems to exist in the room. On the other hand, by fixing a pair of transmitters to the wall 1100, such problems associated with the mobility of the door can be solved.

  In this case, the pair of transmitters are separated from the electronic lock provided at the entrance of the room or the door having the electronic lock, but the distance between the transmitters can be determined in advance. The user position can be specified with reference to the electronic lock provided at the entrance or the door having the electronic lock as in the case described above. When the predetermined position for fixing the pair of transmitters with the electronic lock or the door as a reference is determined, the state in which the door is closed can be used as a reference.

  This also has the advantage that when the transmitter needs to be fed, it is not necessary to perform wiring from the wall to the inside of the door.
