Description

The present invention relates to a vehicle license plate, a managed article such as a jewel, a parking space, a bedding, etc. as a monitored object existing in a monitored environmental part such as a vehicle, a storage place for managed articles, a parking lot, a bed, a safe, a structure, and a room. A device that monitors the condition of the care recipient, the opening and closing of the door of the safe, the soundness of the joint in the structure, the safety information and living condition of the care recipient living in the room, and the monitoring target using this device. It is a monitoring technology for. When the monitoring target is a person, the movement of the monitoring target person in the monitoring area, which is the monitoring target environment part where the target person is active, is measured by the communication noise pattern recognition technology due to the obstacle of the monitoring device (between the tag and the communication device). However, it relates to a monitoring system for monitoring the living conditions of the long-term care recipient by autonomously detecting the indoor activity and safety status of the long-term care recipient using AI technology.

There is a need for monitoring in various areas. For example, it is determined whether the license plate attached to the vehicle is legitimate or illegally attached, or whether information different from the legitimate one is recorded in the IC, and expensive items at the store. As a result, theft and parking lot management are monitored to see if jewelry and the like are displayed in the correct positions and places on the product shelves, and whether vehicles are parked in the parking space in the parking lot. In addition, whether or not the care recipient who is being cared for in a long-term care facility has left the bed, when the person who is permitted to open and close the door of the safe, etc. has opened the door of the safe, pillars, etc. in the structure. It monitors whether or not the joint has lost its soundness due to a natural disaster such as an earthquake, and whether or not an abnormality has occurred by checking the activity and safety status of an elderly person living alone in the living room.

Furthermore, as a monitoring system for checking the activity and safety status of an elderly person living alone and monitoring whether or not an abnormality has occurred, Patent Document 1 uses a wireless communication tag (RFID tag) to monitor the subject. A monitoring system for grasping (monitoring) behavior has been proposed. In this monitoring system, a wireless communication tag is attached to the ankle or the like of the person to be monitored, a signal from the wireless communication tag is received by the receiving device, and the signal received by the receiving device is processed by the information processing device. By processing the signal from the wireless communication tag with the information processing device, the behavior of the person being watched over in the monitoring area (room) is grasped.

Japanese Patent No. 6191163

However, monitoring systems using IC tags and monitoring devices in such various fields have various problems.
To check whether the license plate attached to the vehicle is legitimate or illegally attached, search the database on the PC to see if the vehicle number and the license plate number match. It is necessary to check and visually check whether there is any abnormality even when the lead-type seal that fixes the license plate to the vehicle body is cleverly disguised. For this reason, it is necessary to improve expertise and reliability in determining whether the license plate is legitimate or not.

To check whether jewelry etc. are correctly displayed on the product shelves as high-priced items in the store, the salesperson visually checks the condition of the shelves one by one, checks if there is any vacant space, and vacates it. Since the managed goods are replenished on the goods shelves, it is very troublesome in daily work to check whether the goods are displayed on the goods shelves. Further, even if the managed item is lost from the product shelf due to theft or shoplifting, it is difficult to find it instantly by visual confirmation, and it is difficult to find the theft or shoplifting.

To check whether a vehicle is parked in a parking space in a parking lot, it takes a lot of time and effort because a person looks around the parking lot to check the parked parking space and the vacant parking space. ing. In addition, since the entire parking lot is shot with a video camera, the shot video is checked on the monitor screen, and whether the parking space is vacant or parked is visually judged, misunderstandings and confirmation mistakes occur. easy.

It is very important for the management of the facility to confirm whether or not the care recipient who is being cared for in a long-term care facility has left the bed. The caregiver checks the bed to visually check whether the care recipient is on the bed, and installs an expensive load sensor on the bed for monitoring. Since the caregiver checks the bed one by one even when the care recipient is not away from the bed, the burden on the caregiver is heavy, and the labor and equipment purchase costs are high. In addition, if the caregiver is away from the place where the bed is placed, the caregiver must move to the place where the bed is located or install a monitoring monitor to check whether the care recipient has left the bed. Can't.

In order to confirm whether or not a person who is permitted to open and close the door of a safe, etc. has opened the door of the safe, it is necessary to confirm whether or not the person is authorized. It takes time and effort to present and verify the identity. Moreover, even if a robber who is familiar with the crime prevention system carelessly opens the safe door for the purpose of theft, he / she cannot quickly recognize the date and time when the safe door is opened and whether or not the safe door is opened.

To check whether a joint such as a pillar has lost its soundness due to aging or a natural disaster such as an earthquake in a structure, visually check the joint of the structure by an inspector or the like, or one of the joints. It takes time, money, and labor to confirm the soundness of the structure because the parts are destroyed and the state is grasped.

In addition, in the above-mentioned watching system, always wearing an IC tag on the clothes, ankles, etc. of the person being watched is discriminatory from other care recipients, and the person being watched feels discomfort or pain in the body, ankles, etc. In some cases. Therefore, it is not possible to obtain a good QOL of the person to be watched over.

In addition, the IC tag may be inadvertently dropped from the clothes, body, ankles, etc. of the person being watched over, or the IC tag may be removed from the clothes, body, ankles, etc. of the person being watched over. In such a case, there is a problem and danger that it is not possible to accurately grasp the behavior of the person being watched over in the room.

Furthermore, if the IC tag is once removed from clothing, body, ankles, etc. for some reason, it may be forgotten to attach the IC tag again.

Therefore, according to the present invention, in fields that require monitoring of vehicles, managed article storage areas, parking lots, beds, safes, structures, indoors, etc., it does not take time and effort to perform monitoring, and accurate monitoring is possible. When monitoring the behavior and safety of the watching target person with an RFID tag using a possible monitoring device and this, it is possible to prevent the behavior of the watching target person from becoming unrecognizable due to the non-attachment of the RFID tag, and the watching target person can The purpose is to provide a monitoring system that can autonomously determine situations where there is no pain or discomfort caused by attaching RFID tags.

Consists of. An embodiment in which the monitoring device of the present invention is used will be described below.
[First Embodiment]

In the first embodiment, the monitoring device is used for the portion where the license plate of the vehicle is sealed. In the license plate monitoring device 10 of the present embodiment, the monitoring environment part is the vehicle 11, the monitoring target body is the license plate 13 that is attached to the vehicle body 12 to identify the vehicle, and the license plate 13 is fixed to the vehicle body 12 and sealed. When the RFID tag 15 is attached to the fixture 14 and communication is not possible between the reader / writer 16 provided outside the vehicle 11 and the individually identifiable RFID tag 15 attached to the fixture 14, it is recorded in the IC. The discriminating device 17 determines that the license plate 13 is disguised or has an abnormality when it is different from the vehicle information provided.

As shown in FIG. 1, the license plate monitoring device 10 of the present embodiment is fixed to a fixture 14 mounted on the vehicle body 12 and an individually identifiable RFID tag 15 integrally incorporated in the fixture 14. It has a screw 19 that is screwed into a screw hole 18 provided in the tool 14 and screwed the license plate 13 to the vehicle body.

As shown in FIG. 5, the fixture 14 has a conical tubular shape having different diameters at both ends, and is provided with a screw hole 18 penetrating the central portion. As shown in FIGS. 1 and 2, the fixture 14 is inserted and fitted into the fixture insertion hole 20 provided in the vehicle body 12. The fixture insertion hole 20 has an opening on the mounting surface 21 side on which the license plate 13 is mounted having a smaller diameter than the opening on the vehicle body surface side 22 on the opposite side of the mounting surface 21. Then, by fitting the fixture 14 into the fixture insertion hole 20, the bottom portion of the fixture 14 expands and is fixed to the vehicle body 12 without the risk of falling off.

As shown in FIG. 5, a ring-shaped RFID tag 15 is integrally provided at an axially intermediate portion of the fixture 14. The screw 19 screwed into the screw hole 18 is made of plastic and is formed of a screw head 23 and a male screw portion 24. The screw head 23 is formed by a flange portion 25 formed continuously from the male screw portion 24 and a driver fitting portion 26 integrally provided with the flange portion 25 to fit the tip portion of the driver. .. The driver fitting portion 26 is broken and cut from the flange portion 25 when the driver is rotated with a predetermined torque. Further, the male screw portion 24 of the screw 19 is formed in a tapered shape in which the diameter gradually increases toward the tip side. Therefore, when the screw 19 is screwed into the screw hole 18 of the fixture 14, the diameter of the fixture 14 vehicle body surface side 22 is widened, the fixture 14 is securely fixed to the fixture insertion hole 20, and the RFID tag 15 is attached. It is attached to the vehicle body 12.

Then, in order to attach the license plate 13 to the vehicle body 12 and seal it, the fixture 14 is fitted in the fixture insertion hole 20 of the vehicle body 12, and the license plate 13 is positioned on the attachment surface 21 side. Next, as shown in FIG. 2, after the screw 19 is passed through the license plate 13, it is screwed into the screw hole 18 of the fixture 14. Further, when the screw 19 is tightened and rotated with a predetermined torque, the driver fitting portion 26 is broken from the flange portion 25 as shown in FIG. As a result, the RFID tag 15 is attached to the vehicle body 12 together with the license plate 13, and the license plate 13 is sealed.

When the RFID tag 15 receives a radio wave of a specific frequency from a reader / writer 16 installed near the vehicle 11, for example, in a home parking lot or a contract parking lot where the vehicle 11 is parked, or synchronized with a motion sensor arranged. , A radio wave of a specific frequency is transmitted to the reader / writer 16 toward the reader / writer 16. When the reader / writer 16 receives a radio wave from the individually identifiable RFID tag 15, a signal indicating the reception is sent to the discriminating device 17, and the radio wave from the RFID tag 15 is received on the license plate 13. Judge that there is no abnormality. This result is displayed on the display device 17a. Further, when the reader / writer 16 does not receive the radio wave from the RFID tag 15, the discriminator 17 performs matching comparison with the IC information of the RFID tag and communication between the reader / writer 16 and the individually identifiable RFID tag 15. It is determined that the number plate 13 cannot be (blocked), and that the license plate 13 has some kind of camouflage or abnormality.

For example, if the license plate 13 is carelessly removed from the vehicle body 12 due to theft or the like and the license plate 13 is taken away together with the fixture 14, the RFID tag 15 does not exist on the vehicle body 12 side, so that the license plate 13 is stolen. Can be detected.

Further, when an illegally obtained license plate other than the license plate that should be originally attached to the vehicle 11 is attached to the vehicle body 12, the fixture 14 is damaged when the license plate 13 that has already been attached is forcibly removed from the vehicle body 12. The RFID tag 15 is destroyed. Even if the license plate 13 illegally obtained in this state is attached to the vehicle body 12, communication cannot be performed between the RFID tag 15 and the reader / writer 16, so that the determination device 17 can easily determine that the license plate 13 is disguised or abnormal. You can judge.

Here, the communication state between the individually identifiable RFID tag 15 and the reader / writer 16 will be described. As shown in FIG. 3, the communication distance between the reader / writer 16 and the individually identifiable RFID tag 15 is usually about 2 to 3 m in the passive case, and the communication range is about 50 cm. However, the active RFID tag with power supply can have an effective distance in the range of 20 to 30 m. The transmitting / receiving antenna mounted on the reader / writer 16 can receive the RFID tag 15 which can be individually identified and within the applicable range. That is, even if the position of the RFID tag 15 that can be individually identified with respect to the reader / writer 16 is deviated from the position in front of the reader / writer 16, the angle between the antenna of the reader / writer 16 and the RFID tag 15 can be faced to each other. Then, the reader / writer 16 and the RFID tag 15 can communicate normally. The RFID tag 15 is fixed to the pedestal 15a. In addition, the reader / writer 16 is portable when a police vehicle is mounted or illegal parking is cracked down, and the integrated display device displays information on the target vehicle. In addition, when using a cloud system together, it has the feature that it can be linked to an outdoor WiFi system or another LAN system.

As described above, according to the present embodiment, since the monitoring device is used for the portion where the license plate of the vehicle is sealed, it does not take time and effort to monitor the license plate 13 of the vehicle 11. , Accurate monitoring is possible at a certain distance even from a moving vehicle.

That is, as shown in FIGS. 6 and 7, conventionally, when the license plate 13 is sealed, the screw 27 that attaches the license plate 13 to the vehicle body 12, the pedestal 28 that is attached to the neck portion of the screw 27, and the pedestal 28. It is done with a lead sealing cap 29 that is press-fitted into the screw 27 to seal the head of the screw 27. When replacing the license plate 13 with another illegally obtained license plate, the license plate already attached can be easily removed by breaking the pedestal 28 and the sealing cap 29 and loosening the screw 27. In addition, other illegally obtained license plates can be easily attached by the screw 27.

However, even if the license plate is replaced with another illegally obtained license plate, it is difficult to find that the license plate has been replaced from the appearance. However, in the sealing method of the present embodiment, the RFID tag 15 is attached. By using it to determine whether or not communication with the reader / writer 16 is possible, it is possible to determine the abnormality of the license plate 13, so it is possible to easily collate from the nationwide network linked to the cloud system, and it takes time and effort. Accurate management of the license plate 13 is possible without this.
[Second Embodiment]

In the second embodiment, the monitoring device of the present invention is used for article management for managing the inventory of articles such as precious metals and jewels. In the article management monitoring device 30 of the present embodiment, the monitoring environment part is the managed article storage space 32 for displaying the managed article 31, the monitoring target body is the managed article 31 exhibited at the managed article storage area 32, and the reader / writer 35 An exhibition space provided in the managed article storage area 32, in which an RFID tag 34 capable of individual identification is attached to an exhibition space 33 for displaying the managed article 31 of the managed article storage area 32, and the managed article 31 of the managed article storage area 32 is displayed. When communication is possible between the RFID tag 34 of 33 and the reader / writer 35 provided in the management article storage area 32, the determination device 36 determines that the management article 31 does not exist in the exhibition space 33. In addition, it is possible to link with the cloud system and manage the model number of lost items, image materials, final confirmation time, etc.

RFID tags 34 that can be individually identified are installed on the back plate 39 portion of these exhibition spaces 33. Precious metals, jewels, and the like are displayed in these exhibition spaces 33, and in a state where the precious metals, jewels, and the like are displayed, the individually identifiable RFID tags 34 are covered with the precious metals, jewels, and the like. These RFID tags 34 can be identified corresponding to the positions of the respective exhibition spaces 33, and communication noise is generated with the reader / writer 35, which makes it difficult to read the RFID tags. That is, when communication with the managed article becomes possible, it is determined that the target article is lost or stolen.

The reader / writer 35 is installed on the floor 40 portion of the exhibition corner 32, and is connected to the discrimination device 36 installed on the counter 41 of the exhibition corner 32. Then, a radio wave having a specific frequency is transmitted from the reader / writer 35 to the individually identifiable RFID tag 34 in each exhibition space 33. When precious metals, jewels, etc. are exhibited in all of the plurality of exhibition spaces 33, the individually identifiable RFID tags 34 installed in each exhibition space 33 are covered with precious metals, jewels, etc., and thus a reader. The radio wave from the writer 35 is blocked, and the communication between the RFID tag 34 and the reader / writer 35 is blocked. In this state, the discriminating device 42 determines that there is no abnormality in each exhibition space 33.

When there is no precious metal or jewel in the exhibition space 32, the radio wave from the reader / writer 35 is not blocked by the precious metal or jewel, so that the exhibition space 33 in which the precious metal or jewel does not exist can be individually identified. The RFID tag 34 receives radio waves from the reader / writer 35. The RFID tag 34 that has received the radio wave from the reader / writer 35 transmits a radio wave of a specific frequency to the reader / writer 35. When the reader / writer 35 receives the radio wave transmitted from the individually identifiable RFID tag 34 of the exhibition space 33 in which no precious metal or jewel is present, the reception result is transmitted to the discriminating device 36.

When the reception result from the reader / writer 35 is transmitted, the discriminator 36 identifies the individually identifiable RFID tag 34 to which the radio wave received by the reader / writer 35 is transmitted, and the display in which the RFID tag 34 is installed is installed. Identify the space 33. When the discriminating device 36 discriminates the exhibition space 33 in which the RFID tag 34 to which the radio wave is transmitted is installed, the discriminating device 36 determines the precious metal or jewel in the exhibition space 32 in which the received individually identifiable RFID tag 34 is installed. Etc. are recognized as nonexistent, and the inventory status of precious metals, jewels, etc. in the exhibition space 32 is displayed on the display device 42. By checking the display device 42a with the cloud system, the salesperson can know in detail that there are no precious metals, jewels, or the like in the exhibition space 33.

As described above, according to the article management monitoring device 30 in the present embodiment, it is possible to instantly determine the inventory status of precious metals, jewels, etc. in the exhibition space 33, and the precious metals, jewels, etc. can be placed in the exhibition space 33. It can be quickly replenished and exhibited. In addition, since it is not necessary for the sales staff to always visually check the exhibition space to check the inventory status as in the past, it does not take time and it is possible to accurately monitor the product inventory such as replacement of counterfeit products. It becomes.

That is, conventionally, in order to always confirm whether or not products such as precious metals and jewels, which are managed goods, are displayed in a plurality of exhibition spaces 33 provided on the display shelves 38 installed in stores and the like. , A salesperson was needed to watch over the display shelf 38. In addition, the salesperson must always visually check the exhibition space 33, which is troublesome. Further, it is also necessary to confirm whether or not precious metals, jewels and the like are correctly exhibited in the preset exhibition space 33.

On the other hand, in the article management monitoring device 30 of the present embodiment, the exhibition space 33 is filled with precious metals from the communication state between the individually identifiable RFID tags 34 and the reader / writer 35 provided in the exhibition spaces 33 at a plurality of locations. Since it is possible to instantly determine whether or not a jewel exists, the exhibition space 33 can be quickly replenished with precious metals and jewels. In addition, a salesperson for visually checking the exhibition space 33 becomes unnecessary. Further, by installing the individually identifiable RFID tags 34 that can be identified in each exhibition space 33, precious metals, jewels, and the like to be exhibited can be surely exhibited in the determined exhibition space 33.

Furthermore, if precious metals, jewels, etc. are stolen from the exhibition space 33, they can be found instantly by monitoring the communication status between the RFID tag 34 and the reader / writer 35. It is possible to know that a jewel or the like has been stolen. Detailed information and confirmation by linking the cloud system and reporting to related organizations and police can be carried out promptly.

As shown in FIG. 10, when transmitting and receiving radio waves from the reader / writer 35 to the individually identifiable RFID tags 34 installed in each exhibition space 33, a mirror 43 is provided to diffusely reflect the radio waves. It is also possible to extend the monitoring range within a certain range.

Then, when the reader / writer 49 moves on the moving rail 51, a radio wave having a specific frequency is transmitted to each RFID tag 48 of each parking space 47. When each RFID tag 48 of each parking space 47 receives a radio wave from the reader / writer 49, it transmits a radio wave of a specific frequency toward the reader / writer 49. When the reader / writer 49 receives the radio wave from the RFID tag 48, it transmits to the determination device 50 that the radio wave from the RFID tag 48 has been received. The discriminating device 50 displays this result on the display device 50a.

When the vehicle is not parked in the parking space 47, the RFID tag 48 and the reader / writer 49 communicate with each other, so that the parking space in which the RFID tag 48 communicated with the leader / writer 49 is installed. It is determined that the vehicle 46 does not exist in 47. Further, when the radio wave transmitted from the reader / writer 49 is not received and the reader / writer 49 and the RFID tag 48 do not communicate with each other, the vehicle exists in the parking space 47 in which the RFID tag 48 that does not communicate is installed, and the parking space 47 The determination device 50 determines that the state is not empty. In this case, when the vehicle 46 is parked in the parking space 47, the RFID tag 48 is covered by the vehicle and the radio wave from the reader / writer 49 cannot be received.

In this way, by providing RFID tags 48 in each of the plurality of parking spaces 47 and checking the communication status with the reader / writer 49, the vehicle 46 is parked in the parking space 47 or the parking space 47 is vacant. You can check what it is by using the cloud or network system.

Therefore, the vacancy state of the parking space 47 of the parking lot 45 can be easily confirmed. In addition, the vacancy state of the parking space 47 can be confirmed more accurately than the manager of the parking lot 45 visually confirms. Further, since the vacant state of the parking space 47 can be confirmed only by moving the reader / writer 49 on the moving rail 51, it is not necessary to check the vacant state of the parking space 47.

Next, another example shown in FIGS. 12 and 13 will be described. When checking the vacancy of the parking space 47 in the indoor parking lot 52, an identifiable RFID tag 48 is installed in each of the plurality of parking spaces 47. The reader / writer 49 is installed on the ceiling 53 of the indoor parking lot 52. Then, the reader / writer 49 transmits radio waves from the reader / writer 49 installed on the ceiling 53 toward each RFID tag 48 installed in each parking space 47. When the RFID tag 48, which can individually identify the radio waves from the reader / writer 49, receives the radio waves, the RFID tag 48 transmits the radio waves to the reader / writer 49.

In this case, when the reader / writer 49 receives the radio wave from the individually identifiable RFID tag 48, the discriminating device 50 determines that the parking space 47 in which the RFID tag 48 is installed is empty, and the reader / writer 49 individually determines that the parking space 47 is vacant. If the radio wave from the identifiable RFID tag 48 is not received, the determination device 50 determines that the vehicle exists in the parking space 47 in which the RFID tag 48 is installed. The discriminating device 50 displays this result on the display device 50a. This makes it possible to check the availability of the parking space 47.

When the vehicle 46 is parked in the parking space 47, the RFID tag 48 is covered by the vehicle 46, so that the radio wave from the reader / writer 49 is blocked. When the radio wave from the reader / writer 49 is blocked, the RFID tag 48 cannot receive the radio wave from the reader / writer 49, so that the radio wave cannot be transmitted to the reader / writer 49. Therefore, the reader / writer 49 cannot receive the radio wave from the RFID tag 48.

As described above, the parking lot monitoring device 44 of the present embodiment is provided with RFID tags 48 that can be identified in each of the plurality of parking spaces 47 of the parking lot 45, and is individually identified from the reader / writer 49 installed in the parking lot 45. Since the vacancy status of the parking space 47 of the parking lot 45 can be confirmed by confirming the communication status with the possible RFID tag 48, it is not troublesome and accurate to confirm the vacancy status of the parking space 47. It is possible to check the availability and provide prompt service.

By installing an individually identifiable RFID tag 48 in the parking space 47 and checking the communication status with the reader / writer 49, it is possible to quickly confirm the theft of the vehicle parked in the parking space 47. That is, the vehicle 46 exists in the parking space 47 when the communication state between the RFID tag 48 and the reader / writer 49 installed in the parking space 47 is blocked, but the RFID tag 48 and the reader / writer 49 In the communication state, it means that the vehicle does not exist in the parking space 47, and it can be easily determined that the vehicle 46 has been stolen. By linking with the cloud system, it is possible to report the damage situation to the police and security companies in real time.
[Fourth Embodiment]

In the bed monitoring device 54 of the present embodiment, the monitoring environment part is the bedding 55, the monitoring target body is the care recipient 56 who uses the bedding 55, and can be individually identified by the side plate 57 on the foot side of the bedding 55. When the RFID tag 58 is attached, the reader / writer 60 is attached to the side plate 59 on the head side of the bedding 55, and the care recipient 56 is lying down on the bedding 55, the space between the RFID tag 58 and the reader / writer 60 is When the communication between the RFID tag 58 and the reader / writer 60 is interrupted in the communication state, the discriminating device 61 determines that the care recipient 56 is leaving the bed or trying to get out of bed.

As shown in FIG. 14, the bedding 55 includes a bottom plate 63 on which the bed mat 62 is laid, a side plate 57 on the foot side of the care recipient 56, a side plate 59 on the head side of the care recipient 56, and a bottom plate 63. It is formed of a moving caster 64 provided on the floor surface side. Several RFID tags 58a, 58b, 58c, 58d, 58e are attached to the side plate 57 on the foot side. RFID tags 58a and 58e are arranged on both sides of the side plate 57, RFID tags 58c are arranged on the central portion and the upper side of the side plate 57, and RFID tags 58b and 58d are arranged on both sides of the RFID tag 58c, respectively.

Further, a reader / writer 60 is attached to the side plate 59 on the head side toward the side plate 57 on the foot side via an attachment jig 65. The reader / writer 60 is connected by WiFi to a discrimination device 61 provided in an office or the like where a caregiver who cares for the care recipient 56 is waiting. Then, the radio waves emitted from the reader / writer 60 are applied to several individually identifiable RFID tags 58a, 58b, 58c, 58d, 58e, and the individually identifiable RFID tags 58a, 58b, 58c, 58d, When a radio wave having a specific frequency is emitted from the 58e toward the reader / writer 60, the reader / writer 60 and the RFID tags 58a, 58b, 58c, 58d, and 58e are in a communication state.

When the care recipient 56 is lying on the bedding 55, the radio waves from the reader / writer 60 are applied to several RFID tags 58a, 58b, 58c, 58d, 58e, and several RFID tags 58a, 58b. , 58c, 58d, 58e irradiate the reader / writer 60 with radio waves of a specific frequency. When the reader / writer 60 receives the radio waves from the RFID tags 58a, 58b, 58c, 58d, 58e, it transmits to the discriminating device 61 that the radio waves are transmitted from the RFID tags 58a, 58b, 58c, 58d, 58e. The discriminating device 61 determines that the care recipient 56 is lying on the bedding 55 by transmitting radio waves from the three RFID tags 58a, 58b, 58c, 58d, and 58e. Further, the discriminating device 61 displays this result on the display device 61a.

When the care recipient 56 raises his upper body on the bedding 55, that is, when the care recipient 56 tries to get out of bed and takes an action to get out of bed, the radio waves from the reader / writer 60 are blocked by the care recipient 56, and several individuals Of the RFID tags 58a, 58b, 58c, 58d, 58e that can be identified in the above, the RFID 58c in the center of the side plate 57 and the RFID tags 58b, 58d located on both sides thereof are not irradiated (blocked) by the radio waves from the reader / writer 60. , Radio waves from RFID tags 58b, 58c, 58d are not transmitted to the reader / writer 60. The reader / writer 60 transmits to the determination device 61 that the radio waves from the RFID tags 58b, 58c, and 58d are not transmitted. The discriminating device 61 determines that the care recipient 56 has raised his / her upper body on the bedding 55 and has taken the action of getting out of bed because the radio waves from the individually identifiable RFID tags 58b, 58c, and 58d have not been transmitted.

Further, when the care recipient 56 positions his / her feet on the side of the bedding 55 from above the bedding 55, puts his / her feet on the floor, and sits sideways with respect to the bedding 55, the side plates 57 can be individually identified. The radio wave from the reader / writer 60 to the RFID tag 58a or the RFID tag 58e is blocked. When the radio wave from the reader / writer 60 to the RFID tag 58a or the RFID tag 58e is blocked, the radio wave from the RFID tag 58a or the RFID tag 58e is not transmitted to the reader / writer 60. The reader / writer 60 transmits to the determination device 61 that the radio waves from the RFID tag 58a or the RFID tag 58e have not been transmitted. The determination device 61 determines that the care recipient 56 is sitting on the bedding 55 and is about to get out of bed because the radio wave from the RFID tag 58a or the RFID tag 58e is not transmitted.

As described above, in the bed monitoring device 54 of the present embodiment, a plurality of individually identifiable RFID tags 58a, 58b, 58c, 58d, 58e are attached to the bedding 55, and the RFID tags 58a are attached according to the position of the care recipient 56. , 58b, 58c, 58d, 58e and the reader / writer 60 can be machine-learned in the same coding as the flag signal to determine the complete bed leaving or bed leaving prediction.

According to the bed monitoring device 54 of the present embodiment, the state of the care recipient 56 on the bedding 55 can be accurately monitored without the caregiver's time and effort. That is, conventionally, it has been difficult to grasp that the care recipient 56 leaves the bedding 55 at a caregiver station or the like away from the bedding 55, for example, a hospital room or the like. Therefore, it is conceivable to shoot and monitor the room where the bed is placed with a video camera or the like, but the caregiver has to look at the monitor screen of the shot video, which is troublesome. In addition, the privacy of the care recipient cannot be protected by the monitor using the video camera, and good QOL cannot be obtained.

However, in the bed monitoring device 54 of the present embodiment, the discriminating device 61 determines the behavior of the care recipient 56 on the bedding 55 based on the communication state between the RFID tags 58a, 58b, 58c, 58d, 58e and the reader / writer 60. Therefore, it does not take time and effort. Further, even if the communication state between the RFID tags 58a, 58b, 58c, 58d, 58e and the reader / writer 60 is temporarily interrupted due to the care recipient 56 turning over or the like, the time during which the communication state is interrupted is less than a predetermined time. Since it can be determined that the care recipient 56 has just turned over, the behavior of the care recipient 56 on the bedding 55 can be accurately monitored. In addition, by enabling links with cloud systems, etc., technologies such as AI can be introduced, and it is possible to construct an autonomous judgment system for multiple targets.
[Fifth Embodiment]

The discriminating device 72 determines that the doors 68a and 68b of the safe 67 have been opened by the reader / writer 71 receiving the radio waves from the individual identifiable RFID tags 69 and 69. The discriminating device 72 displays the result on the display device 72a or automatically enables a link to a cloud system or the like to report a crime to a related department or generate an alarm. The reader / writer 71 and the discriminating device 72 are hidden by a shield so as not to be visually inspected.

In this case, since the predetermined manager and the permitter who are permitted to open and close the safe 67 bring an ID tag that permits the opening of both doors 68a and 68b of the safe 67, the discriminating device 72 is a safe. Even if both doors 68a and 68b of 67 are opened, it is not judged to be a thief. If the discriminator 72 does not have the permitted ID tag, it cannot be recognized, and the reader / writer 71 and the individual identifiable RFID tags 69 and 69 communicate with each other to cause both the safe 67 and the safe 67 by the thief. It is determined that the doors 68a and 68b are inadvertently opened. Therefore, since the thief does not have an ID tag for recognition, the crime is found and information such as the date and time is recorded as soon as both doors 68a and 68b of the safe 67 are opened. By making it possible to link with cloud systems, even if the thief escapes, it will be recognized by the alibi verification. It should be noted that identification that enables tag encryption is performed, and tag information that is not intended is excluded. For these information analyzes, pattern analysis using AI, machine learning, etc. is performed.

Next, the monitoring procedure in the monitoring system 121 of the present embodiment, that is, the operation of the discriminating device 106 will be described with reference to the flowchart shown in FIG. In FIG. 26, when the monitoring system 121 is turned on in step S1, that is, the power of the reader / writer 105, the discriminator 106, and the motion sensor 1111 is turned on, the motion sensor 111 is set in step S2. It is determined whether or not the care recipient 122 is detected. When it is determined that the motion sensor 111 has detected the care recipient 122, the discriminating device 106 identifies in which location the motion sensor 111 has detected the care recipient 122 in step S3. When the motion sensor 111 that detected the care recipient 122 was specified in step S3, radio waves were transmitted from the reader / writer 105 corresponding to the motion sensor 111 identified in step S4, and individual identifiable RFID tags were arranged. Detecting the radio wave response transmitted to the area The received wave of each identifiable RFID tag 104 is confirmed from the radio wave transmitting unit 9.

In step S5, the determination device 106 determines whether or not the reader / writer 105 has received radio waves from the RFID tag 104. If the reader / writer 105 can receive the radio wave from the RFID tag 104 with respect to the radio wave transmitted from the reader / writer 105 within a predetermined time, the determination device 106 determines that the care recipient 122 has no abnormality in step S6. .. In step S5, when an abnormality occurs in the care recipient 122, for example, when the care recipient falls on the floor, the human body is prevented from receiving radio waves from the individually identifiable RFID tag 104 arranged on the floor with the reader / writer 105. It cannot be implemented due to radio interference.

It is determined in step S7 whether or not the predetermined time has elapsed in a state where the reader / writer 105 cannot receive the radio wave from the RFID tag 104, and if the transmitted radio wave from the RFID tag cannot be received even after the predetermined time has elapsed, the determination is made. The device 106 determines in step S8 that an abnormality has occurred in the care recipient 122, that is, an abnormality such as falling on the floor has occurred, and in step S9, the display screen 134 indicates that the abnormality has occurred. Display and report via network system, etc.

If the radio wave from the RFID tag 104 is received before the lapse of a predetermined time in step S7, step S2 and subsequent steps are repeatedly executed. Then, in step S10, it is determined whether or not the monitoring system 121 is in the OFF state, and if it is not in the OFF state, after confirming whether or not there is a response from the motion sensor, step S2 and the following are executed again. When the watching system 121 is turned off, the watching system ends.

In step S5, the care recipient 122 falls on the floor and does not receive radio waves from the identifiable RFID tag 104, that is, the care recipient 122 transmits radio waves between the reader / writer 105 and the RFID tag 104. The determination device 106 determines whether or not the care recipient 122 has an abnormality due to the blocking. Further, the presence or absence of the response of the motion sensor is confirmed. To explain another example, when the care recipient 122 moves to the entrance area 112, the radio wave of the reader / writer 105 to the RFID tag 104 provided on the door 120 for the response of the motion sensor is blocked, and the care recipient 122 enters the entrance. It is detected that the user has moved to the area 112.

Next, when the care recipient 122 approaches the entrance door 118 in order to open the entrance door 118, the motion sensor 111 detects this. When the motion sensor 111 detects the care recipient 122, the reader / writer 105 responds to radio waves toward the RFID tag 104 corresponding to the motion sensor 111.
