Description

  The present invention relates to an object movement confirmation system, an object movement confirmation method, and an object movement confirmation program for managing movement of an object to be moved with a person.

  There are many things that must be taken when moving from one area to another, such as when going out or attending a meeting held in a conference room. For example, a mobile phone or a wallet may be a must-have item when going out. When attending a meeting, there are cases where a pre-designated document or a personal computer storing data is a must-have item. These must-have items vary from person to person and from situation to situation. Even if the person is conscious about forgetfulness, it is not easy to improve, and it is especially likely to occur when the person is panicking. When you notice something left behind and return to your home or work, you waste valuable time. Also, if you notice that you have forgotten your wallet when paying for meals, delaying the time you notice a lost item can bother others and damage your trust. On business, forgetting the necessary documents not only delays the contract procedure but also destroys the contract itself.

  Therefore, as a first related technique of the present invention, a belonging list is created, and for example, when going out, indispensable items are inspected before going out. However, the inventory list itself may be missing or lost, which is often useless in critical cases. Also, when you are in a hurry or in the dark, you often read the inventory list incompletely and neglect to check the essential items.

  In addition to this, as a second related technique of the present invention, it is proposed to attach an RFID (Radio Frequency Identification) tag to a carried item and transmit it as necessary (see, for example, Patent Document 1). With this second related technology, a user attaches an RFID tag to an object to be carried when going out such as a mobile phone, a notebook, or a wallet. Then, ID information of each RFID tag is stored. When necessary, the user activates the RFID reader to transmit radio waves to the RFID tag, receives response radio waves from the RFID tag, and compares them with the stored ID information. Then, if the stored ID information and each ID information of the RFID tag completely match, it is determined that there is no forgotten thing. On the other hand, if there is an item whose ID information cannot be detected, it can be understood that the item to which the corresponding RFID tag is attached is a forgotten item.

Japanese Patent Laying-Open No. 2005-085186 (paragraphs 0017 to 0020, FIG. 1)

  However, in the second related technique, the place where the RFID reader is activated becomes a problem. For example, it is assumed that the user is installed on the entrance shoe box when going out of the house. Then, it is assumed that the RFID reader is activated while putting his belongings on the entrance floor and wearing shoes, confirming that all necessary items are available, turning off the RFID reader and going out. However, after wearing shoes, you may leave some of the objects placed on the entrance floor or forget to remove small items such as keys that have been dropped on the floor during the operation of wearing shoes. is there. Also, if you are in a hurry, you may forget to turn on the RFID reader and go out even though some of the essential items are missing. The RFID reader may be always turned on. However, in this case as well, an object existing within a predetermined distance range from the RFID reader is only checked, and no check is performed until the user goes out. Furthermore, it is complicated to frequently notify the user of confirmation.

  Considering the case where a user attends a meeting at a company, even if the RFID reader is placed in his / her seat, it is not suitable for detection of indispensable items that must be brought to the meeting. The RFID reader receives response radio waves not only from documents and articles put together for attending the meeting, but also from RFID tags attached to the meeting essentials hidden under the nearby documents. For this reason, if the user brings only the documents and articles that are put together for attending the meeting as if all necessary items have been prepared, forgotten items may occur. Of course, in this case as well, if the RFID reader is misunderstood as being turned on, and there is no error notification for the lost item, there is a risk that the lost item will be lost.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an object movement confirmation system, an object movement confirmation method, and an object movement confirmation program that can surely confirm the movement of a necessary object together with the movement of a person.

  In the present invention, (a) gate means for partitioning the entrance and exit of a person disposed between a first area as a predetermined space area and a second area connected to the first area; Radio signal shielding control means for preventing the passage of the radio signal between the first area and the second area when the gate means is closed and allowing the radio signal to pass between these areas when the gate means is open. And (c) on the side of the second region of the gate means described above, when the wireless signal shielding control means prevents passage of the wireless signal, the wireless signal from the first region does not reach, And a second area side radio signal receiving means arranged at a predetermined location where the radio signal from the first area reaches when the radio signal shielding control means passes the radio signal, and (d) a specific The above-mentioned game is performed from the first area described above. A radio signal transmitting means on a mobile indispensable object attached to a mobile indispensable object as a specific object that moves from the first area to the second area without fail when moving to the second area through the means; E) When the specific person moves from the first area to the second area through the gate means as described above, each object to be moved from the first area to the second area together with the second area. A wireless signal transmitting means on the moving object attached to each of the moving objects, (f) a gate means closing detecting means for detecting when the gate means is closed, and (g) a closing detection of the gate means. When the means detects that the gate means is closed, the radio signal transmitted from the radio signal transmitting means on the mobile must-have is received by the second area side radio signal receiving means. Under these conditions, the second area-side radio signal receiving means determines whether or not each of the moving objects has been described above by determining whether or not each of the wireless signals transmitted from the above-mentioned moving signal on the moving object is received. The object movement confirmation system includes a second area movement necessary movement confirmation unit that individually determines whether the second area has been moved.

  In the present invention, (a) the first area described above from the first area as the person who moves from the first area as the predetermined space area to the second area connected thereto moves. The status of the radio signal transmitting means attached to the object to be moved to the second area of the radio signal transmitting means attached to each of the objects that may move to the second area is A first region state setting step for setting a first region state indicating that the object is present in the first region; and (b) existing at the boundary between the first region and the second region, When a specific person moves from the first area to the second area by opening the gate means having an electromagnetic shielding function except in the open state, the time point when the gate means is closed after the movement is detected. Gate means closed when moving area 2 And (c) when it is detected that the gate means is closed in the second area movement gate means closing detection step, the first area state is set in the first area state. These objects have moved to the second area by determining whether the signal transmitted by the wireless signal transmitting means attached to the set object is received on the second area side. The object movement confirmation method comprises a second movement necessary object movement confirmation step during the movement of the region for individually determining whether or not.

  Further, according to the present invention, as the object movement confirmation program, (a) as described above in accordance with the movement of the person who is moving from the first area as the predetermined space area to the second area connected thereto.

A means closing detection means 16 and a second movement required object movement confirmation means 17 are provided. Here, the gate means 11 partitions the entrance and exit of a person arranged between the first area as a predetermined space area and the second area connected to the first area. The radio signal shielding control means 12 prevents the radio signal from passing between the first area and the second area when the gate means 11 is closed, and the radio signal between these areas when the gate means 11 is open. Pass through. The second area-side radio signal receiving means 13 is arranged at a predetermined location where the above-described radio signal from the first area reaches with the gate means 11 closed. In the state where the gate means 11 is closed, the above-mentioned radio signal from the above-mentioned first area does not reach at this place. When the specific person moves from the first area to the second area through the gate means 11, the radio signal transmitting means 14 on the movement-necessary object always moves from the first area to the second area. It is attached to a moveable item as a specific item that moves to the area. When the specific person moves from the first area to the second area through the gate means 11, the second signal is transmitted from the first area to the second area. Are attached to each of the moving objects as the respective objects to be moved to the region. The gate means closing detection means 16 detects when the gate means 11 is closed. When the second means moves, the necessary movement confirmation means 17 detects that the second means radio signal receiving means 13 described above when the gate means close detection means 16 detects that the gate means 11 is closed. By determining whether or not each of the wireless signals transmitted from the upper wireless signal transmitting means 15 can be received, it is determined individually whether or not these necessary moving objects have moved to the second area. At this time, it is a condition that the radio signal transmitted from the radio signal transmitting means 14 on the mobile must-have item is received by the second area side radio signal receiving means 13.

The setting is made on the object to be moved to the second area without fail from the radio signal transmitting means attached to each of the objects that may move from the first area to the second area. The status of the attached wireless signal transmission means is targeted. In the first region state setting step 21, the first region state indicating that these objects exist in the first region is set. In the second area moving gate means closing detection step 22, the gate means that exists at the boundary between the first area and the second area and has an electromagnetic shielding function other than the open state is set as a detection target. That is, when the gate means is opened and a specific person moves from the first area to the second area, the time point when the gate means is closed after the movement is detected. In the movement necessity confirmation step 23 when the second area is moved, the movement of the object is determined when it is detected in the second area movement gate means closing detection step 22 that the gate means is closed. That is, whether or not the signal transmitted by the wireless signal transmitting means attached to the object set in the first region state in the first region state setting step 21 is received can be determined on the second region side. By determining, it is individually determined whether or not these objects have moved to the second region.

Let it run. Here, in the first area state setting process 31, the status is set in accordance with the movement of the person who moves from the first area as the predetermined space area to the second area connected thereto. The setting is made on the object to be moved to the second area without fail from the radio signal transmitting means attached to each of the objects that may move from the first area to the second area. The status of the attached wireless signal transmission means is targeted. In the first area state setting process 31, the first area state indicating that these objects exist in the first area is set. In the second area moving gate means closing detection process 32, the gate means that exists at the boundary between the first area and the second area and has an electromagnetic shielding function other than the open state is set as a detection target. That is, when the gate means is opened and a specific person moves from the first area to the second area, the time point when the gate means is closed after the movement is detected. In the second area movement necessary movement confirmation process 33, the movement of the object is determined when it is detected in the second area movement gate means close detection process 32 that the gate means is closed. That is, whether or not the signal transmitted from the wireless signal transmitting means attached to the object set in the first region state in the first region state setting process 31 is received can be determined on the second region side. By determining, it is individually determined whether or not these objects have moved to the second region.

  <Embodiment of the Invention>

  Next, an embodiment of the present invention will be described.

  FIG. 4 shows a main part of the configuration of the object movement confirmation system according to the embodiment of the present invention. In the object movement confirmation system 100 of the present embodiment, the entrance door 103 for entering and exiting the house 102 where the user 101 resides has a special specification as will be described later. The entrance door 103 is connected to an object location notification determination device 104 installed inside the house 102 by a communication line 105. In this embodiment, the communication line 105 is wired, but may be wireless.

  FIG. 4 shows a state where the user 101 is inside the house 102. A user 101 carries the RFID tag to each of a plurality of predetermined objects that should be carried when going out and should be present inside the house 102 at home. Here, the active RFID tag is a wireless IC (Integrated Circuit) tag incorporating a battery. Unlike passive RFID tags that do not incorporate batteries, active RFID tags can communicate within a range of several tens of meters. “Attachment” may be attached to an object by any method, and includes not only attachment by an instrument but also attachment, embedding or mixing.

In this embodiment, the relationship between an object and an active RFID tag is shown as follows. A first active RFID tag 112 ₁ is attached to a key 111 ₁ for locking the entrance door 103 as a first object. A second active RFID tag 112 ₂ is attached to the wallet 111 ₂ as the second object. A third active RFID tag 112 ₃ is attached to a mobile phone 111 ₃ possessed by the user 101 as a third object. A fourth active RFID tag 112 ₄ is attached to a regular ticket 111 ₄ as a fourth object. A fifth active RFID tag 112 ₅ is attached to the watch 111 ₅ as the fifth object.

  FIG. 5 specifically shows the configuration of the entrance door and the object location notification determination device. This will be described with reference to FIG.

The entrance door 103 has an electromagnetic shielding plate 121 incorporated on the entire surface of the door so that the thickness direction of the entrance door is divided into two. Moreover, although not shown in figure, the same electromagnetic shielding board is embed | buried in the inside of the wall around the entrance door 103 in the house 102 as needed. This is also one in the state in which the front door 103 is closed in the first to fifth active RFID tag 112 _{1-112 5} is present in at least a house 102, and these just outside the front door 103 This is to ensure that communication is not possible. The electromagnetic shielding plate 121 is generally composed of a thin metal plate, but electromagnetic shielding glass can be used at a location corresponding to the transparent portion of the entrance door 103.

  Inside the entrance door 103, an inner RFID reader 122 is embedded inside the house 102 with an electromagnetic shielding plate 121 as a boundary, and an outer RFID reader 123 is embedded outside the house 102. The front door 103 has a structure in which a side portion of a plate material (not shown) is opened and closed by a hinge structure that rotates about a rotation axis perpendicular to the floor surface. The angle sensor 124 disposed inside the entrance door 103 determines the presence or absence of locking by detecting the rotation angle of the rotary lock 125 of the entrance door 103.

  The inner RFID reader 122 reads event information sent from the active RFID tag 112 when the active RFID tag 112 is present inside the house 102. The electromagnetic shielding plate 121 shields radio waves transmitted from the active RFID tag 112 even when the active RFID tag 112 exists inside the house 102 when the entrance door 103 is closed. Therefore, the outside RFID reader 123 cannot read event information sent from the active RFID tag 112 existing inside the house 102 when the entrance door 103 is closed. The outer RFID reader 123 reads event information transmitted from the active RFID tag 112 when the active RFID tag 112 exists outside the house 102.

  The object location notification determination device 104 receives event information read by the inner RFID reader 122 and the outer RFID reader 123 and information representing the rotation angle of the front door 103 output from the angle sensor 124 and processes them. ing. Specifically, the object location notification determination device 104 includes a CPU (Central Processing Unit) 131 and a main control unit 133 including a memory 132 that stores a program executed by the CPU 131. The main control unit 133 is connected to the status management unit 134, the read information storage unit 135, the error notification unit 136, and the door close / open determination unit 137.

Here, the status management unit 134 manages the states of the _first to fifth objects 111 _{1 to} 111 ₅ . For this reason, the status management unit 134 includes an input unit 138 that receives input from the user 101 and a status storage unit 139. Read information storage unit 135 temporarily stores information from the active RFID tag 112 _{1-112 5} of the first to fifth read the inner RFID reader 122 and an outer RFID reader 123. These pieces of information are overwritten on the status table 141 provided in the status storage unit 139 together with the input information from the user 101. The status table 141 will be described later.

  The error notification unit 136 has a function of performing necessary notification to the user 101 in a predetermined case such as when a forgotten thing occurs. The door closing / opening determining unit 137 has a function of determining whether the entrance door 103 is opened or closed. Each unit other than the main control unit 133 in the object location notification determination device 104 may be configured by hardware, and at least a part of these units is implemented by software by the CPU 131 executing a program stored in the memory 132. A function may be realized.

FIG. 6 shows the structure of the status table. The status table 141, for each of the active RFID tag 112 _{1-112 5} of the first to 5 shown in FIG. 4, and the tag ID as a signal pattern for identification, the object 111 became attached to the target The name and current status (States) are recorded. Here, the status “IN” refers to a state that is set when the object 111 that is the management target of the forgotten item exists inside the house 102. In addition, the status “OUT” indicates a state in which it is confirmed that the object 111 that is the management target of the forgotten item exists outside the house 102. Further, the status “Home” indicates that the corresponding object 111 is in an initial state. In the initial state, it is not yet determined whether or not the object 111 is a management target of forgotten items.

  FIG. 7 shows a series of flows from when the user initializes the object movement confirmation system according to the present embodiment inside the house to go out. This will be described with reference to FIGS.

User 101, before going out, by operating the input unit 138 of the object location notification determination unit 104, to initialize all active RFID tags 112 ₁ to 112 ₅ of the first to fifth, these Is set to “Home” (step S201). Next, the user 101 uses the input unit 138 to update the status of the object 111 to be carried when going out of the _first to fifth objects 111 _{1 to} 111 ₅ to “IN” (step S202). ). At this time, it is assumed that it is confirmed that the object 111 whose status is “IN” exists inside the house 102. The status is not set to “IN” except when the user takes out. For example, it is assumed that come out with the clock 111 ₅ as a fifth object, its status as shown in FIG. 6 remains "Home".

When the processing of step S202 is completed, the object location notification determination device 104 monitors the detection result of the angle sensor 124 and waits for the entrance door 103 to change from the unlocked state to the locked state (step S203). For example, it is assumed that the user 101 opens the entrance door 103 for going out, goes out of the entrance, and is locked using the key 111 ₁ as the first object (Y). At this time, the object location notification determination device 104 checks whether the outer RFID reader 123 has detected any of the active RFID tags 112 whose status is “IN” (step S204).

In this example, since the user 101 is locked from outside using the key 111 ₁ , the outer RFID reader 123 detects at least the first active RFID tag 112 ₁ corresponding to the key 111 ₁ . Therefore, the outer RFID reader 123 detects one of the active RFID tags 112 whose status is “IN” (step S204: Y). In this situation, it is confirmed whether or not the _first active RFID tag 112 ₁ corresponding to the key 111 ₁ exists in the active RFID tag 112 read by the outer RFID reader 123 (step S205). In this example, a situation that does not exist does not occur. In a case other than this example, if the first active RFID tag 112 ₁ does not exist (step S205: N), for example, the housemate locks, and the user 101 himself places the key 111 ₁ inside the house 102. You may have forgotten. Therefore, in this case, the error notification unit 136 notifies the user 101 that there is something left behind (step S206). Since it is confirmed that the active RFID tag 112 read by the outer RFID reader 123 is outside the house 102, these statuses are updated to “OUT” (step S207). Thereafter, the stored contents of the read information storage unit 135 are cleared (step S208), and the process is ended (END).

Of course, when the key 111 ₁ is forgotten inside the house 102 and the automatic lock mechanism is not used, the user 101 can open the front door 103 and return the forgotten item. When the front door 103 is locked (step S203: Y), if the outside RFID reader 123 does not detect any of the active RFID tags 112 (step S204: N), the read information storage unit 135 is read. Is stored (step S209), and the process returns to step S203. This is because the fact that the user 101 has locked the entrance door 103 without having any of the objects 111 whose status is set to “IN” corresponds to, for example, the following case and is not regarded as going out.

(1) When the user 101 is locked from the inside without opening the entrance door 103 without going out of the house 102 for security purposes.
(2) The entrance door 103 is temporarily opened to deal with an outpatient such as a postman or a courier, but is locked without going out.
(3) When the user temporarily goes out of the entrance door 103 due to requirements such as dealing with an outpatient or going to a nearby garbage collection site, but later returning to the interior and locking.

If the outside RFID reader 123 detects that the key 111 ₁ of the user 101 is outside the entrance door 103 in step S205 (Y), the status is set to “IN” in addition to the key 111 _{1 in} step S202. It is determined whether or not the object 111 exists (step S210). Assume that the user 101 has set the status to “IN” for only the key 111 _{1 in} step S202. In this case (N), all the objects 111 for going out are aligned and go out. Therefore, the object location notification determination device 104 does not operate the error notification unit 136 and updates the read status of the _first active RFID tag 1121 to “OUT” (step S207). Thereafter, the stored contents of the read information storage unit 135 are cleared (step S208), and the process is ended (END).

On the other hand, it is assumed in step S202 that there is an object 111 whose status is set to “IN” in addition to the key 111 ₁ . In this case (step S210: Y), it is checked whether the outer RFID reader 123 has detected all of the active RFID tags 112 whose status is set to “IN” in step S202 (step S211). It does not matter whether the object 111 whose status is not set to “IN” is also taken out.

If the user 101 possesses at least all the objects 111 whose status is “IN” (step S211: Y), the object location notification determination device 104 does not operate the error notification unit 136. Then, the statuses of all active RFID tags 112 detected by the outer RFID reader 123 are updated to “OUT” (step S207). For example, the user 101 outside the entrance door 103 in possession of clock 111 ₅ as a fifth object. If all objects 111 that this time the status is "IN" by the user 101 possesses (step S211: Y), the status is additional takeout watch 111 ₅ which has been a "Home" is possible It is. However, the timepiece 111 ₅ I did not set as an object to be carried on the go, located in this state may become unclear. Therefore, with the outer RFID reader 123 detects the active RFID tag 112 ₅ 5 in step S207, it will update the status to "OUT" also this tag.

In the other hand, the step S202 for example, the status as a lost wallet 111 ₂ as a second object that has been set as "IN", there is a case where the conditions shown in step S211 are not satisfied. In this case (N), the object location notification determination unit 104 activates the error notification unit 136 to notify that forgot wallet 111 ₂ (step S206). Since it is confirmed that the active RFID tag 112 read by the outer RFID reader 123 is outside the house 102, these statuses are updated to “OUT” (step S207). Thereafter, the stored contents of the read information storage unit 135 are cleared (step S208), and the process is ended (END). In this case, the user 101 can open the entrance door 103 and return to retrieve the lost item.

  8 to 10 show the state after the update of the status table in each case. This will be described with reference to FIGS. Here, it is assumed that the status table 141 is in the state shown in FIG. 6 when the process of step S202 is completed.

FIG. 8 shows a case where the user 101 goes out with a key 111 ₁ as a _first object, a wallet 111 ₂ as a _second object, and a mobile phone 111 ₃ as a third object as planned. . In this example, the timepiece 111 ₅ as a fifth object is not brought out to the outside of the planned house 102. In this case, since all the conditions for taking out are satisfied, the error notification unit 136 of the object location notification determination device 104 does not perform a warning notification in step S206.

Figure 9 shows a case where the clock 111 ₅ as a fifth object that did not carry the case of FIG. 8, was brought out key 111 _1, with wallet 111 ₂ and the portable telephone 111 ₃ out of the house 102. The fifth status of the active type RFID tag 112 ₅ corresponding to the cellular phone 111 ₃ is updated from "Home" to "OUT." Also in this example, all the conditions for taking out are satisfied. Therefore, the error notification unit 136 of the object location notification determination device 104 does not perform a warning notification in step S206.

10, the user 101 is a mobile phone 111 ₃ as the object of the key 111 ₁ and the third as the first object to go out to carry planned, not carrying a wallet 111 ₂ as a second object This is the case. In this example, the timepiece 111 ₅ as a fifth object is not brought out to the outside of the planned house 102. In this case, the condition for taking out is not satisfied. Therefore, the error notification unit 136 of the object location notification determining unit 104 performs warning notification that forgot wallet 111 ₂ in step S206. At this time, the user 101 selects one of the two correspondences.

The first response is that the user 111 returns to the house 102 for the purse 111 ₂ . If the wallet 111 ₂ is held outside the house 102 and locked, the status of the second active RFID tag 112 ₂ attached to the wallet 111 ₂ is updated from “IN” to “OUT”. As a result, the status table 141 changes to the state shown in FIG.

Second correspondence is to go out with a notice that you have forgotten your wallet 111 _2. For example, only go to buy a can of juice in the vicinity of the store, in the case such as leaves with a coin purse in the pocket, possession of the purse 111 ₂ is not required. If the user 101 accepts the notification from the error notification unit 136 as described above, the user 101 can go out as it is. In this case, the recorded contents of the status table 141 are in the state at the time of update in step S207.

  FIG. 11 shows a process of the object location notification determination apparatus when the user returns home. This will be described with reference to FIGS.

  The door close / open determination unit 137 of the object location notification determination device 104 waits for the entrance door 103 to open once and then close (step S231). When such an operation is detected for the entrance door 103 (Y), the object location notification determination device 104 detects the active RFID tag 112 whose inside RFID reader 122 is inside the entrance door 103 and whose status is “OUT”. It is determined whether or not it has been performed (step S232). When such a detection is not performed (N), a person other than the user 101 such as a family member returns to the house 102. This is an item that is not managed by the object location notification determination device 104. Therefore, the object location notification determination device 104 clears the stored content of the read information storage unit 135 (step S236) and ends the processing (end).

  In contrast, it is assumed that the inner RFID reader 122 detects the active RFID tag 112 whose status is “OUT” inside the front door 103 (step S232: Y). In this case, the object location notification determination device 104 refers to the status table 141 of the status storage unit 139. Then, it is determined whether or not the inner RFID reader 122 has detected all of the active RFID tags 112 whose status is “OUT” (step S233). When such a detection is not performed (N), there is a possibility that the user forgot to bring the object 111 corresponding to the active RFID tag 112 that was not detected. Therefore, in this case, the error notification unit 136 gives a warning notification indicating the object 111 (step S234). Then, all the statuses of the active RFID tag 112 read by the inner RFID reader 122 inside the front door 103 that are “OUT” are updated to “IN” (step S235). Thereafter, the stored contents of the read information storage unit 135 are cleared (step S236), and the process is ended (END).

  On the other hand, in step S233, it is determined that the inner RFID reader 122 has detected all of the active RFID tags 112 whose status is “OUT” (Y). In this case, the object 111 to which these active RFID tags 112 are attached has returned to the house 102. Therefore, the process proceeds to step S235.

As a result of the return processing described above, the status of the object 111 that does not need to be taken out together at the next outing may be “IN”. For example, when the user 101 is not scheduled to go out carrying the clock 111 ₅ as a fifth object is the case as to go out in possession of this. In this case, originally the contents of status table 141 should be the state shown in FIG. 8, a fifth status of the active RFID tag 112 ₅ as shown in FIG. 9 when coming home is changed to "OUT." As a result, the fifth active RFID tag 112 ₅ status is updated to "IN" in the processing in step S235. When the state of the status table 141 left untreated this state, if not carry a clock 111 ₅ as a fifth object of the error notification unit 136 notifies the things left behind to the user 101 when performing the next go (step S206) . In other words, clock 111 ₅ not essential baggage of change across essential baggage when going out, so that the error is signaled to be carried.

  In order to prevent such inconvenience, the status of the status table 141 that is “IN” is changed from “IN” to “Home” for items that are not essential items when going out next time. It needs to be changed. Of course, the status of the object 111 for which it is determined whether it is an essential carry-on item when going out is set to “IN”, and when the error notification (step S206) for not taking out is made, the user 101 determines whether or not he / she has it You may make it judge.

According to this embodiment of the present invention as described above, the key 111 ₁ to lock the entrance door 103 with that only the outer RFID reader 123 detects, and to determine that the user 101 goes out. Accordingly, an error notification is not erroneously performed for an operation for opening and closing the front door 103 other than going out. As a result, when the user is not locked, such as when talking outside the house or going to throw away trash, the object movement confirmation system 100 can be excluded from the management target, and the user 101 can easily use the system.

In the present embodiment, the first to fifth active RFID tags 112 _{1 to} 112 ₅ are attached to the first to _fifth objects 111 _{1 to} 111 ₅ in association with each other. Therefore, unlike the passive RFID tag does not incorporate a battery, the inner first to fifth active RFID tag 112 _{1-112 5} of which are arranged in the front door 103 side be present at the position of the house 102 throat It can be detected by the RFID reader 122 or the outer RFID reader 123.

Incidentally, if by incorporating a circuit that detects the first through fifth active RFID tag 112 _{1-112 5} for example, vibration or acceleration, limit the time for transmitting only the information prescribed time after performing these detection can do. Thus, depending on the capacity of the internal battery of active RFID tags 112 ₁ to 112 _5, it is possible a few years or more of long-term communication. Therefore, there is no need to provide a power switch, and there is no risk of missing detection of essential items due to forgetting to turn on the power switch.

Further, if error notification error notification unit 136 of the present embodiment was linked with alarm notification function of the mobile phone 111 _3, without noticing the error notification when a user 101 leaves the house 102, notified be able to. The notification may be performed by sound or a buzzer sounding, or by sending an e-mail.

  <First Modification of Invention>

  FIG. 12 shows a main part of the configuration of the object movement confirmation system according to the first modification of the present invention. In FIG. 12, the same parts as those in FIG. 4 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

In the object movement confirmation system 100A of the first modification, the first to fifth passive RFIDs are used instead of the first to _fifth active RFID tags 112 _{1 to} 1125 attached to the object 111 in the embodiment. Tags 312 _{1 to} 312 ₅ are used. First to fifth passive RFID tag 312 _{1-312 5} of this modification is to communicate using the frequency of the UHF (Ultra-High Frequency) band. The first to fifth passive RFID tags 312 _{1 to} 312 ₅ do not incorporate batteries. Therefore, communication with the inner RFID reader 122 and the outer RFID reader 123 shown in FIG. 5 is not possible unless the entrance door 103 is close to a distance of several tens of centimeters.

  However, even in the object movement confirmation system 100 </ b> A of the first modification, the user 101 exists at a location sufficiently close to the inner RFID reader 122 and the outer RFID reader 123 immediately after the entrance door 103 is locked. Therefore, the passive RFID tag 312 attached to the object 111 carried by the user 101 can be detected by the processes shown in FIGS. Therefore, in the object movement confirmation system 100A of the first modification, it is possible to determine whether the object 111 exists inside or outside the house 102 in exactly the same manner as the object movement confirmation system 100 of the embodiment. It is.

In the first variant of the object transfer confirmation system 100A, a passive RFID tag 312 _{1-312 5} of the first to fifth without integral battery. Therefore, there is no possibility that the detection error of the object 111 due to the battery running out occurs. Moreover, the battery replacement work is unnecessary. Furthermore, the object movement confirmation system 100A can be configured at a low cost by the amount that the passive RFID tag 312 does not require a battery.
<Second Modification of Invention>

  FIG. 13 shows a main part of the configuration of the object movement confirmation system according to the second modification of the present invention. In FIG. 13, the same parts as those in FIG. 4 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

In the object movement confirmation system 100B of the second modified example, the first active RFID tag 112 ₁ is attached to a shoe as the _first object 111B ₁ used by the user 101 for going out. The second to fifth objects 111 _{2 to} 111 ₅ are the same as in the previous embodiment.

The user 101 uses sandals and other shoes (not shown) to which the active RFID tag 112 is not attached when the user 101 is not going out, such as taking out garbage in the neighborhood. If the first active RFID tag 112 ₁ is attached to the insole of the shoe 111B ₁ , it can easily cope with changing to another shoe.

  FIG. 14 shows a series of flows from when the user initializes the object movement confirmation system according to the present embodiment inside the house to go out in the case of the second modification. In FIG. 14, the same steps as those in FIG. 7 are denoted by the same step numbers, and description thereof will be omitted as appropriate. This will be described with reference to FIGS.

In the second modification, after the initialization of the step S201, the user 101 status of the active RFID tag 112 of another object 111 to carry when going out and shoes 111B ₁ for out using the input unit 138 Is set to “IN” (step S202).

  When the processing of step S202 is completed, the object location notification determination device 104 monitors the detection result of the angle sensor 124 and waits for the entrance door 103 to change from the unlocked state to the locked state (step S203). For example, it is assumed that the user 101 opens the entrance door 103 for going out, goes out of the entrance and is locked (Y). At this time, the object location notification determination device 104 checks whether the outer RFID reader 123 has detected any of the active RFID tags 112 whose status is “IN” (step S204). If detected (Y), it is determined whether or not the object 111 whose status is set to “IN” has been detected by the outer RFID reader 123 without performing the process of step S205 in FIG. 7 (step S401).

  If the outer RFID reader 123 does not detect the object 111 whose status is set to “IN” (step S401: N), the process proceeds to step S207. When the outer RFID reader 123 detects the object 111 whose status is set to “IN” (step S401: Y), the process proceeds to step S211. The subsequent processing is the same as in the embodiment. Moreover, the process at the time of returning described in FIG. 11 is the same process in the second modified example.

Thus, according to the second modification of the present invention, unlike the key 111 ₁ of the embodiment, the shoe 111B ₁ is not forgotten when going out. Therefore, the process shown in FIG. 14 has an advantage of being simplified compared to the process shown in FIG. Further, in the embodiment, when a plurality of persons share the key 111 _{1 of the} house 102, the user 101's essential carry-on items are checked even when used by other than the user 101, and an error occurs. There is a fear. In the second modification, since each person uses shoes separately, such inconvenience does not occur. In addition, any chance, if the other person was wearing the wrong shoes 111B ₁ of the user 101 because the mistake at the time of going out is found, it is possible to prevent the wear mistake of shoes. Further, in the embodiment, since the active RFID tag 112 ₁ is attached to the key 111 ₁ , attachment is impossible depending on the type of the key. It does not occur.

  In the above description, the keys and shoes are positioned as objects deeply related to going out. However, if there is an object having a similar function, it is possible to associate the object with the lock. For example, if a blind person or a physically handicapped person goes out using his / her cane, a wireless IC tag such as an active RFID tag may be attached to the cane. Of course. In addition, various kinds of objects such as UV protection glasses for going out and wigs for going out can be associated with going out.

  Further, the door lock need not be detected by the angle sensor 124. It may be a door that can be locked without inserting the key into the keyhole. Whatever detection method is used, the locking and the data reading side such as the outer RFID reader 123 need only be linked.

  Furthermore, although embodiment and the modification demonstrated the entrance / exit of the house 102, it is not restricted to this. For example, the present invention can be applied to confirming personal belongings or carry-on items for entry / exit of offices, buildings, vehicles, ships, or specific areas that manage security. In accordance with this, it is natural that the name of the “entrance door” used in the embodiment and the modification also changes appropriately.

  In the embodiment, the entrance door 103 is opened and closed with a hinge structure, but other types of doors such as a sliding door may be used. That is, the name is not particularly limited as long as it is a place where people enter and exit.
